AGRICULTURAL PROACTIVE AIR/SURFACE DECONTAMINATION SYSTEM AND DEVICES

Abstract

A system for decontaminating/neutralizing breathable air and surfaces in an occupied enclosed space, i.e., agricultural greenhouse, includes mounting an atmospheric hydroxyl radical generator along an inside surface of the atmospheric hydroxyl radical generator having respective opposite air inlets and air outlets. The hydroxyl radical generator includes a polygonal housing supporting a plurality of spaced crystal-spliced UV optics, which are tubular, medical grade pure quartz optics to emit/irradiate ultraviolet in the nanometer wavelength/ultraviolet spectrum of between 100 and 400 nanometers for deactivating and neutralizing atmospheric chemicals and pathogens in breathable air and surfaces. The hydroxyl radicals contact the walls of the reaction chamber housing. The hydroxyl radicals become created and excited to react quickly with impurities including VOC, virus, bacteria and fungi, rendering them inactivated and neutral. The breathable air passes through the polygonal housing and is decontaminated and neutralized of impurities before entering the occupied enclosed space.

DETAILED DESCRIPTION OF THE DRAWINGS

[0040] FIG. 1 shows a hydroxyl generator 1, including a polygonal-shaped housing, including a bracket brace 14 for supporting crystal-spliced UV optics 12 and 13 within respective C-shaped spring clasps 12a and 13a, which are each respectively mounted on bracket brace 14, which are mounted parallel lengthwise to each other inside the clamshell hexagon housing, but staggered so that UV optic 12 is on a different side of the bracket 14 from the side on which UV optic 13 is located, wherein the crystal spliced UV optics 12 and 13 each have a length that runs substantially the entire length of the housing of the hydroxyl generator 1. A preferred example for the crystal-spliced UV optics 12 and 13 is the GPH457T5L/4P UV Optic 4-pin Base 18″ GPH457T5 of Light Spectrum Enterprises of Southampton these optics 12 and 13 are typically 18 inches long and are made of quartz. The tubular optics 12 and 13 are composed of pure Medical Grade quartz crystal in the portion of the optics which creates the hydroxyls. The present invention adds additional frequencies to the pure crystal optics. This tubular lamp optics 12 and 13 generate ‘Harmonic’ bio-mimicry nonchemical process of the present invention enables the production of desired atmospheric hydroxyls at a rate commensurate with the VOC/Bio loading in that particular space to be treated with the hydroxyls.

[0041] In contrast to the medical grade quartz tubular optics, it is noted that total glass tubes cannot be used when generating UV. The glass would simply be vaporized. Some companies use a fusion of glass and quartz crystal, which is not optimal as the glass portion creates a frequency that actually attracts contaminants. This problematic action neutralizes the desired UV action. Such a fusion lamp of glass and quartz crystal is cheaper to produce, however the poor performance of the lamp would be the end result.

[0042] Other similar Medical Grade quartz tubed UV optics can be used. The optic 12 and 13 are preferably symmetrically positioned in the housing of the hydroxyl generator 1, as shown in FIGS. 3 and 4 to operate most efficiently, but where in FIG. 3 the crystal spliced UV optics 12 and 13 are staggered so that UV optic 12 is on a different side of the bracket brace 14 from the side on which UV optic 13 is located. FIG. 4 shows an alternate embodiment where there are two pairs of UV optics, namely 112,113 and 112a, 113a. The UV optics 112, 113 are staggered to the right on one bottom side of the horizontal bracket brace 114, but are separated by upright bracket brace 114. Likewise, UV optics 112a and 113a are respectively staggered to the left on the opposite top side of the horizontal bracket brace 114, also separated from each other by upright bracket brace 114. Optics pairs 112, 113 and 112a, 113a are supported within pairs of respective C-shaped spring clasps 112c, 113c and 112d, 113d, which pairs of optics 112, 113 and 112a, 113a are each respectively mounted on bracket brace 114, and which pairs of optics 112, 113 and 112a, 113a are mounted parallel lengthwise to each other inside the clamshell hexagon housing 1.

[0043] The clamshell hexagon housing hydroxyl generator 1 has a clamshell configuration, including a clamshell top wall 2, upper side walls 7, 8, 9 and 10, a hinge 6 for opening the polygonal clamshell housing 1 and a bottom clamshell portion, including a bottom wall 4 and angle-oriented walls 11 and 11a, whereby the polygon housing opens hinge 6 to expose the inside of the hydroxyl generator 1 for maintenance and/or repair. In addition, the polygon hydroxyl generator enclosure can be removed from the air duct wall 40A for such maintenance and repair. The hydroxyl generator also includes an adjacent electronic control box 20, which is attachable to the clamshell housing of the hydroxyl generator 1. Alternatively, as shown in FIGS. 3 and 4, the electronic control box 20 is preferably located outside of the air path, which may be a duct or other conduit.it can alternatively be attached outside of the duct. It communicates with the UV optics wirelessly. The reason for the polygon shape is that the hydroxyl generators generated by the crystal-spliced UV optics 12 and 13 are scattered upon being generated by the optics 12 and 13, but they dissipate quickly if not activated by contact with reflective non-absorbent surfaces inside the respective walls of the polygon. The purpose of the polygon shape is that when the hydroxyl radicals are generated, they are emitted radially in all directions from the UV crystal-spliced optics 12 and 13 and normally would dissipate when scattered radially from the optics. In order to permit the hydroxyl radicals to maintain their desired electron charge and ability to contact and inactivate mold, volatile organic compounds, pathogens, bacteria, virus, etc., they need to reflect and refract off of the reflective non-absorbent walls continuously, within the reaction chamber confined space. As atmospheric hydroxyls are being activated by being created and excited in back-and-forth activity, the air inside the air duct/plenum 40a will contact the activated hydroxyl radicals with the end result of the neutralization of any impurities, such as VOCs, virus, bacteria, fungi, etc., in the air and surfaces.

[0044] Furthermore, once these radicals are emitted, they can penetrate any crevices in any area, such as between seats of mass transit vehicles, between the surfaces of desks; anywhere where ultraviolet light by itself would not be capable of eradicating the undesirable VOCs, fungi, virus, bacteria, etc. The polygon-shaped housing is strategically located within an air duct wall, which can be in a building which has sub walls extending to various rooms in the building.

[0045] As shown in the end view of FIG. 3, the inside of the polygon housing 1 is located below the field of vision within the sealed off plenum so that the ultraviolet (UV) crystal-spliced tubular optics 12 and 13 will not be exposed to the eyes of any observers. Therefore, while the hydroxyl radicals are being generated, the UV energy which create hydroxyl generation from optics 12 and 13 are completely sealed off so that when the optics 12 and 13 are operational, the UV light emanating therefrom will not penetrate outside of the polygonal housing. There is no restriction regarding the active flow of the hydroxyls inside the hydroxyl generator 1 and no interference with the excitement of the hydroxyls produced by the exposure of ambient water vapor within the polygon shaped housing with the UV optics 12 and 13 irradiating light that causes the —OH radicals to form.

[0046] FIG. 4 shows an alternate embodiment for a four optic version, where polygon hydroxyl generator enclosure 101, having top wall 102, side walls 107, 108, 109, 110 of an upper shell, as well as lower walls 105, 111a, 111b of the clamshell housing. FIG. 4 also shows the electronics control box 120. The respective pairs of optics 112, 113 are supported within respective pairs of C-shaped spring clasps 112a and 113a, which are each respectively mounted on bracket brace 114, which are mounted parallel lengthwise to each other inside the clamshell hexagon housing 101. Clamshell housing 101 is openable via hinge 106.

[0047] FIG. 5 is a block diagram showing the network and electronics of the control box 20. Initially AC power 23 of 110 VAC is converted by converter 22 to low voltage 12 VDC, or else a low voltage battery alternatively delivers 12 VDC to a secure Key Switch 22a, to provide power to the Master Events Controller 20, which may have a microprocessor 21. The Master Events Controller 20 also receives input from sensors, such as Air Flow Sensor 25, UV Light Sensor 26, Proximity Switch 27 (detecting opening of the enclosure), Timer 30 and Voltage Monitor Sensor 31. These sensors provide Sensor Input to the Master Events Controller 20. Power Switching in the Master Events Controller 20 sends 12V Pulse Width Modulation data to a PWM Speed Controlled Fan 34, to send air through the hydroxyl generator unit 1 or 101, or to stop the flow of air when needed for safety and maintenance situations. The Power Switching also sends data via a Large Serve Outlet (LSO) to a Relay, which controls the Ballast 32, providing power to the Crystal UV Optics 12, which creates the needed hydroxyls within the hydroxyl generators 1 or 101. The Master Events Controller 20 also has a Communications Output, which can send data via a Controller Area Network (CAN) to a Visual Display 29 for user feedback. The Communications Output of the Master Events Controller 20 also sends digital data wirelessly as output to Status Feedback Units. The Communications Output of the Master Events Controller 20 also sends Wi-Fi/Bluetooth Signal output to Wireless input devices 28 for Wireless user feedback during use.

[0048] FIG. 5A is a diagrammatic flow chart, showing the electronic control box 20 of FIGS. 1, 2 and 3, which is also equivalent to the electronic control box 120 of FIG. 4. Adjacent to the hydroxyl generator 1 or 101, which in FIGS. 1-3, the hydroxyl generators are attached by brackets 19 to the electronic control box 20. Similarly, the electronic control box 120 is attached by brackets 119 of FIG. 4.

[0049] In the diagrammatic flow chart of FIG. 5A, related to the electrical block diagram of FIG. 5, the control box 20 includes a microprocessor 21 for controlling the sensors and switches, which control the operation of the optics 12 and 13, or 112 and 113, of the hydroxyl generators 1 shown in FIGS. 1-3 and 4 respectively. There is also a power source being either a DC low-voltage battery 24, or an AC plug 23, to provide higher-voltage AC power. When the AC is used, a converter 22 can be provided to convert high-voltage AC to low-voltage DC power for operating any of the sensors and control elements within box 20. Box 25 of FIG. 5A discloses the detector 25 to detect whether airflow is on, so that the optics 12 and 13 will only be on after airflow is confirmed, so that they are not on when there is no airflow. Box 26 of the diagrammatic flow chart of FIG. 5A discloses the sensor 26 for detecting emitted light, and providing feedback to replace optics, including a secondary backup optic, which is also disclosed in box 26 of the flowchart of FIG. 5A. Box 27 of the diagrammatic flow chart of FIG. 5A discloses a detector with a proximity switch 27 detecting opening of the enclosure, and thereafter used to turn off the optics 12 and 13, to protect people from being exposed to the possible harmful UV light emitted from the optics 12 and 13. This detector with the proximity switch 27 shown in box 27 of the diagrammatic flow chart of FIG. 5A also includes a limit switch, a micro switch and sensors. Box 28 of the diagrammatic flow chart of FIG. 5A discloses the mobile phone application connection 28 for user feedback by wireless communication, such as Wi-Fi or Bluetooth® communications, between the operator, the control box 20 and hydroxyl generator 1 itself, together with a timer. The control box 20 also includes the LCD user feedback system 29, with a timer shown in box 29 of the diagrammatic flow chart of FIG. 5A with a timer, as well as a further timer 30 shown in box 30 of the diagrammatic flow chart of FIG. 5A, to provide feedback for regular maintenance. The voltage and frequency of AC main supply sensor 31 is shown in box 31 of the diagrammatic flow chart of FIG. 5A, Box 32 of the diagrammatic flow chart of FIG. 5A shows the voltage and frequency of the monitor of the ballast power outfit 32. Box 33 of the diagrammatic flow chart of FIG. 5A discloses a fire sensor 33, which detects excess heat in the system. Box 34 of the diagrammatic flow chart of FIG. 5A discloses a real time clock 34 which controls any fans providing and activating the airflow through the polygon hydroxyl generators 1.

[0050] In the alternate embodiment shown in block diagram FIG. 5B, tailored specifically for a hydroponic greenhouse, such as shown in FIGS. 6 and 6A. there are disclosed therein shown the following differences of block diagram FIG. 5B from block diagram FIG. 5, wherein in block diagram FIG. 5B the following features are shown: [0051] 1. The key switch (22a) can alternatively be positioned before the power supply (22); [0052] 2. The key switch (22a) can alternatively be a pushbutton; [0053] 3. The power supply (22) can alternatively be included in the Master Events Controller (MEC) 20; [0054] 4. The user feedback display (29) of FIG. 5 is not needed in FIG. 5B, because the WiFi/Bluetooth communication works with a mobile application; [0055] 5. The PWM Speed controlled fan (34) of FIG. 5 is not needed, because the hydroxyl generator 1 will be located in an existing duct with moving air; and, [0056] 6. The power to the relay (not numbered) in FIG. 5 can alternatively be provided by the Master Events Controller (MEC) 20 in FIG. 5B.

[0057] In the preferred agricultural hydroponic embodiment, as shown in FIGS. 6 and 6A, the hydroxyl generators can be used in greenhouses, for producing plants hydroponically, such as medicinal or other botanical plants, which are grown agriculturally inside a greenhouse. The plants are mounted in the greenhouse on troughs and tables, typically hydroponically, where the roots are held in place by media, such as coconut fibers, vermiculite, perlite, growstones, rockwool, pine shavings, rice hulls, peat moss, soil, sand or other mineral materials, so that a portion of the roots are soaked in hydroponic fluid, for irrigation and fertigation, and the upper part of the roots are exposed to air, which is brought through with hydroxyl radicals from the hydroxyl generators. For example, in FIG. 6, hydroxyl generator 310 (polygonal-shaped) is positioned in the greenhouse 300 in an air duct 330.

[0058] The greenhouse has a top roof area 300a, side walls 300b and 300c, and a base ground level 300d. The greenhouse 300 is adjacent to a utility room 350, which has utility controls 320 for controlling the electronics and mechanics of the system, as well as a hydroponic fluid source 390, which provides the hydroponic fluid through a pipe conduit 360. The pipe 360 has the lower parts of the roots and the media soaking in the fluid, with an upper portion of the roots and media being exposed to air of the plants 370, which have roots 370a held in place by media 370B. The hydroponic fluid 370e is provided through the hydroponic fluid pipe 360. The polygonal-shaped hydroxyl generators 310 are produced in an enclosed air duct, which is preferably a fan 351, and produces an airflow into an air duct 330, which emanates horizontally from the fan 351, or other air source, then makes an upward 90-degree turn, through an air duct portion 330a, which then turns at 90 degrees horizontally at an upper portion of the utility room 350 through a horizontal portion 330b, within which is located the hydroxyl generator, just before a further downward air duct portion 330c emanates downward to the level of trough 334 inside the greenhouse, so that the air from the downward portion 330c of the air duct is then sent horizontally through a flexible sock sleeve 340, having multiple upper apertures 341 to permit the radical hydroxyl flows below and then around the hydroponic fluid pipe, and then contacting the air and plant roots 370a of the plants 370, within the media, such as the coconut fiber 370b. Optionally, an overhead mister hose 365 may be provided in case the plants are not hydroponically bred. In any case, the hydroxyls, whether they are blown or pumped through the root system and media in the greenhouse trough in the hydroponic growing system in the greenhouse, the hydroxyl radicals are exposed to the portions of the roots 370a and growing media 370b, so that they can be misted exposed therein while being irrigated and/or fertigated, either hydroponically, or alternatively within conventional soil media. In this version, the greenhouse 300 is connected to the utility room 350. The hydroxyl generators are installed in a strategic position at the top of the air duct 330b, before the hydroxylated air is sent downward through portion 330c of undulating air duct 330 spanning from utility laboratory room 350 and greenhouse 300 and then the air filled with hydroxyls is sent to the flexible sock sleeve 340, having upper apertures 341 for release of the hydroxyls to intermingle with the plant roots 370a of the hydroponically grown plants 370 located above the parallel troughs 334 of greenhouse 300. Flexible sock sleeve 340 is tapered to decrease in diameter towards its distal end, to accommodate for air pressure loss, due to decreasing air flow through the length of the flexible sock sleeve 340.

[0059] FIG. 6A shows a detailed view of the hydroxyl flexible sleeve 340, with hydroxyls 302 therein and the arrows indicate the flow of the hydroxyls around the lower portion of the pipe with the fertigation and irrigation fluids for the hydroponics where the lower levels of the roots 370a are provided, but where the upper level of the roots exposed to air within the media 370b are then exposed to the hydroxyls of the plants 370. The trough 334 is shown below the flexible sock sleeve 340. The hydroxyls are introduced into air surrounding exposed roots, leaves, stems, vascular or phloem tissues of the plant.

[0060] In an alternate embodiment in a non-hydroponic system, as shown in FIG. 7, a greenhouse 400 includes hydroxyl generators 410 and 411, which are provided either adjacent to an intake fan 451 for airflow through and out the greenhouse 400 through exhaust fan 451 and/or motorized or pressurized shutter outlets 480, 481. A trough 434 is provided for the plants and there may be a drip irrigation hose 470 with apertures for irrigation of hydroponic growing media 470c of the roots 470a of plants 470, where the hydroxyls less generated by hydroxyl generator 411 will mingle within the air exposed portions of the roots and in the media 470b of the plants 470.
