DETAILED DESCRIPTION
[0026] The gas accumulation and combustion control device is designed to prevent the accumulation of flammable and toxic gases in a residential, commercial, laboratory, or industrial setting.
[0027] As shown in
[0028] The sorption box is an enclosure, preferably made of metal, such as aluminum or steel, a hard plastic, or a combination thereof. As shown in
[0029] In one variation, as shown in
[0030] The sorption box may be configured to connect adaptably to tubing, piping, vents, or other HVAC components. The sorption box may be built into new HVAC systems or retrofitted into existing systems. It may be screwed or nailed in, or otherwise locked into place. The inlet and/or outlet walls may feature mechanisms, such as latch or screw-fit components, to adapt to the HVAC components. The sorption box may be positioned such that it is substantially or at least partly inside a building with the outlet wall positioned outside the building. Alternatively, the sorption box may be located inside a room in which filtering and adsorption is desired, or behind the wall of such a room but with access thereto. In one variation, the sorption box is independent of other HVAC components but is instead a stand-alone machine. As shown in
[0031] The chambers may feature hatches 408 which provide access to the sorption units from outside the sorption box, but are also capable of being closed in order to prevent access thereof. The hatches may be substantially continuous and in line with the passage walls 410, being hingedly or slidably attached and engaged to the stationary portion of the passage walls.
[0032] In one variation, the sorption chambers themselves may be removable from the sorption box. The chambers may be fitted into chamber openings 412 that are disposed in the passage walls of the sorption box. The chambers and chamber openings may be screw-fit, constructed so that the former fits tightly into the latter, or otherwise configured to prevent the chambers from falling out of the chamber openings due to gravity or other unintended forces without grossly impeding a user from removing them. The chambers themselves may be disposed on a track 414 disposed inside the cavity and slidably removable from the sorption box 416.
[0033] In one embodiment, the ventilation system may comprise an inlet fan and an outlet fan, with the inlet fan positioned close to the inlet wall and the outlet fan being positioned next to the outlet wall. The fans have a diameter approximating the sorption box diameter, so that all air entering the inlet wall may encounter and be handled by the inlet fan, and all air passing through the cavity may encounter and be handled by the outlet fan. As shown in
[0034] In the preferred embodiment described above, as shown in
[0035] The conversion between containment-type and pass-through type, as shown in
[0036] The compressor may be disposed between the inlet fan and/or door and the cavity, and configured to reduce the volume of the gas in order to facilitate sorption by the sorption units.
[0037] The gas collection container may be rigid or made of inflatable material. It is preferably in fluid communication with the cavity, thereby leeching densified and contaminated air from the sorption box. This gas collection container may, in one variation, be intermediated by a ventilation fan in order to accelerate gas collection.
[0038] Transport of contaminated or cleaned air may be facilitated by a series of valves intermediating the various components of the device. For example, a first set of valves may control flow from the compressor to the cavity, a second set of valves may control flow from the cavity to the gas collection container, and a third set of valves may control flow from the cavity to outlet fans or to the outlet wall.
[0039] The dust filter is (dust filters are) preferably disposed within or behind the inlet wall(s). The dust filter is configured to catch particles smaller than 1 mm in diameter which the inlet wall(s) otherwise might not catch, such as dust particles, which are between 2.5 and 10 microns.
[0040] As shown in
[0041] The sensor system may include a gas sensor configured to detect flammable or toxic gases. Examples of gas sensors include metal oxide based gas sensor, optical gas sensor, electrochemical gas sensor, capacitance-based gas sensor, calorimetric gas sensor, or acoustic based gas sensor. The gas sensor may consist of sensing elements such as a gas sensing layer, a heater coil, an electrode line, a tubular ceramic, or an electrode. Examples of gases which may be sensed include methane, butane, LPG, smoke, alcohol, ethanol, CNG gas, natural gas, carbon monoxide, carbon dioxide, nitrogen oxides, chlorine, hydrogen gas, ozone, hydrogen sulfide, ammonia, benzene, toluene, propane, formaldehyde, and other various toxic or flammable gases.
[0042] Upon detecting a designated concentration level of an undesirable gas, the sensor system is configured to transmit a gas detection signal to a wireless receiver inside the control system. The designated concentration levels of undesirable gases may be based on lower flammability limits or on recognized toxicity levels, which are levels where the gas becomes dangerous to human or animal health. In one variation, as shown in
[0043] The sensor system may be configured to detect the concentration of a given gas, approximate that concentration numerically, and transmit the numerical concentration to the control system or directly to a visual display to enable users or operators to view and track the gas levels. The concentration levels may be captured and transmitted in real time, or captured at reoccurring intervals, such as once an hour, once a day, or once a week. The captured concentration levels may be saved in a database for future reference. In one variation, the concentration levels are transmitted to a dedicated module or mobile device, where they are converted into trending data, and the trending data may be saved on the module or device and displayed upon request by the user.
[0044] As shown in
[0045] The control system comprises a set of processors and wireless receivers disposed within a container. Upon receiving the wireless detection signal from the mobile device 906, the control system is configured to initiate or permit an electric flow to the ventilation system 908, thereby turning on the fans. In the variation described above, the control system may permit electric flow to the ventilation system upon receiving an upper threshold gas detection signal, but only turn on a warning signal upon receiving a lower threshold gas detection signal. The warning signal may be a light, such as a bulb, LED, or other illumination component, configured to illuminate in either a steady stream or flashing pattern, and which is signalled electrically or wirelessly by the control system. The warning signal may be a text message or other notification sent to a human user or operator's phone or a separate display screen. The warning signal may also be an audio transmission, such as a beeping sound, emitted from a speaker disposed on or in the sorption box or else positioned in the targeted room and wirelessly connected to the control system. An exemplary manifestation of the control system may be a SCADA (supervisory control and data acquisition) system, which includes software and hardware elements enabling the control of processes locally or remotely, the monitoring, gathering, and processing of real-time data, interaction with devices such as sensors, valves, pumps, and motors though a human-machine interface, and the recording of events into a log file.
[0046] In one variation, the user may communicate with the control system and/or sensor system using the dedicated module or mobile device via a dedicated user interface. The user may observe the concentration levels in real time and observe historical concentration data. The user may send a signal to the control system to turn on the fan system based on target concentration levels, which may be set by the user using the user interface, and/or manually.
[0047] The control system and/or the ventilation system may be mechanically, hydraulically, or battery operated, feature a plug for inserting into an electrical outlet, and/or hardwired into a building's electrical wiring. If the control system is battery operated, the battery may be contained in a battery box, with the battery box being disposed inside or adjacent to the control system. The battery box may be positioned so that it is accessible from outside the sorption box so that the battery may be easily removed and replaced. The battery box may feature a port which passes through the walls of the sorption box and configured to receive a battery charger.
[0048] The control system may impose various activity programs on the components of the device, principally by controlling the electrical flow to the one or more fans and the one or more motors, thereby turning the one or more fans on or off, increasing or decreasing rotations speeds of the one or more fans, or switching the directional orientation between the outlet orientation and the inlet orientation. The control system may also control the valves that permit or block fluid flow from entering the device, moving throughout the device, (such as between the compressor and the cavity, the cavity and the gas collection container, the cavity and the outlet fans), and exiting the device. The doors comprise a row of shutters, such that when the shutters are oriented perpendicular to a door, the door is in an open state, and when the shutters are oriented substantially in line with the door, the door is in a closed state. The shutters may be electrically and mechanically controlled by the control system as well.
[0049] In one program, the control system determines if the sorption units have reached capacity based on the internal contaminant gas signals, and if so, imposes a containment program on the ventilation system, with the containment program featuring either all of the one or more fans turned off or turned on and put into the inlet orientation. The containment program may be subceeded by a collection program, in which the valves connecting the cavity to the gas collection containers are opened for a span of time, ideally until the gas collection containers are filled to capacity, hereafter the valves are shut off. To assist in determining whether the gas collection containers are filled to capacity, a pressure sensor in signal communication with the control system may be disposed between the valve and the gas collection container. This gas collection container may be removably attached to the cavity such that once it is removed, it may be sealed up. In one variation, the valve is principally attached to the gas collection container and is removed with it. In another variation, the valve is principally attached to the cavity, and the gas collection container must be sealed by other means, such as via a cap or a separate valve.
[0050] In another program, the control system determines if the contaminant gas levels in the atmosphere are too high (although this may also be the default assumption for the control system, and therefore a default program). If so, the control system imposes a concentration program on the ventilation system, with the concentration program set for increasing the speed of the one or more fans in an inlet orientation or switching one or more fans from an outlet orientation to an inlet orientation.
[0051] In yet another program, the control system determines if the sorption box pressure is too high, and if so, imposes a pass-through program on the ventilation system, with the pass-through program featuring at least one fan in an outlet orientation.
[0052] In one variation, as shown in
[0053] The pressure regulator features a pressure sensor designed to detect the measurement of gas pressure. Based on the degree of pressure imposed on the sensor, the pressure regulator generates an electrical signal to convey the pressure measurement to other components. As shown in
[0054] As shown in
[0055] The sorption box may be sized proportional to the space in which filtering and gas sorption is sought, and may be calculated according to the equations shown in
[0056] Additional examples of sorbents include catalytic sorbents, photocatalysts, polymerics, MOFS, Alkali metals such as carbonates and oxides, amine solid sorbents, carbonaceous materials such as carbon nanotubes and carbon molecular sieves, zeolites, mesoporous silica, alumina, hydrotalcite-like compounds (HTICs), metal-based oxides such as CaO based sorbents, porous MgO, Sodium Zirconate, Lithium compounds, and Na.sub.2O promoted alumina, activated carbons, sorbents. So-called photocatalysts, such as titanium dioxide, work to disinfect by, upon being disposed to light, generate hydroxyl radicals.
[0057] In one embodiment, one or more sorbents and/or the sorption box are coated with crystalline coating material, which is configured to generated hydroxyl radicals upon being exposed to light. Hydroxyl radicals are observed to denature viruses, such as SARS-Coronavirus, by damaging viral exterior features, such as the crown or spike proteins, puncturing the lipid membrane, and exposing the RNA contents. The crystalline coating material may include metal organic frameworks (MOF), which operate as desiccants by providing an enlarged, porous, surface area with external-facing molecules in a cage-like structure that are likely to bind and thereby capture free-floating molecules. The crystalline coating material may be added to traditional sorbents as an applied layer or may be used as sorbents by themselves. The use of crystalline coating material in conjunction with other sorbents and/or the sorption box may also provide disinfecting effects on bacterial and fungal growth. In another embodiment, the sorption box is coupled with an Ultra Violet (UV) emitting bulb or light source. The use of UV is an effective method of denaturing viruses, and acts to damage the exterior features of the virus, thereby exposing and further damaging the RNA contents. As shown in
[0058] In one embodiment, the sorption box features a heating mechanism, such as conventional heating elements found in portable heaters, and which are electrically connected to the control system. The control system may provide for manual control over heating, automatic control based on feedback provided by thermometrical sensors, or a combination of the two, such that a user can program the heating elements to activate upon the detection of a lower threshold temperature and deactivate upon the detection of a higher threshold temperature. The user may also program the control system to activate the heating elements based on sorbent activation requirements. The heating system may also be used for humidity control in order to maintain the efficacy of the sorption units. Dehumidification may be scheduled or programmed to occur upon the detection of a set humidity threshold. Finally, the control system may be configured to apply a desorption program upon detecting an adsorption saturation point has been reached or based on a schedule.
[0059] In one embodiment, the sorption units may feature a multi-sorbent complex, featuring multiple layers stacked together, with each layer comprising a different material, thickness, density, or configuration of sorbents. The layers may be stacked in a pile, or radially such that a first layer comprises a core which is then surrounded nearly entirely by a second layer, and so on.
[0060] In another embodiment as shown in
[0061] As previously discussed, the control system may transmit a communication to a user's mobile device or to a dedicated device conveying sorption system activity, including instructions to replace one or more sorption units. The control system may also be configured to transmit communications to third parties such as fire departments. The transmission may be wirelessly via Bluetooth, WiFi, or some other wireless protocol. In one embodiment, each sorption box and/or sorption unit is equipped with a scale or other weight measuring mechanism to determine when the sorption unit has reached its saturation point. The system may also make this determination based on measurements of inlet flowrate and/or concentration. The system may also include a user interface configured to inform the user as to the location of sorption unit disposal or recycling services. Such information may be displayed as pins on a map. The system may either itself comprise or be coupled to a GPS application.
