DESCRIPTION

(11) The present invention relates to a System and Method (FIG. 1) that uses only kinetic energy to clean the contamination present in the atmospheric air, in a passive manner, without using any other type of energy that would increase the contamination instead of diminishing it. The contamination floating in the air of any urban area is known as smog. This smog is a gray cloud composed of hundreds of toxic elements, particulate matter of different sizes, chemical elements which are the byproduct of human activity and gases which are naturally present in the atmospheric environment such as CO2 (Carbon Dioxide) and Ozone.

(12) In a preferred embodiment, the present invention uses the internal combustion vehicles (FIG. 2 and FIG. 3) which are one of the major contributors to the smog, to install air purifying means (FIG. 1) that use the kinetic energy derived from the movement of those vehicles as they travel their normal routes, to extract the pollutant elements from the air and to capture them, to be disposed of later and in a safe manner (FIG. 4).

(13) Advantageously, the System and Method described in this new invention eliminates the need of a filter element to clean the particulate matter from the environmental air, which is the solution used by most air cleaners. Those filter elements create air resistance, clog easily and require constant and expensive maintenance.

(14) Moreover, the present invention avoids the main issue found in other air cleaners, which require strong energy means to suck in the air and push it through filters that retain the particulate matter carried by the air. Furthermore, each of those commercial appliances clean only a certain quantity of dirty air found near its surroundings. Such devices are an ecological contradiction and paradox because the enormous amount of energy that is required to move large amounts of air would itself produce a contamination equal or worse than the amount of pollutants collected.

(15) In a preferred embodiment, at the center of the present invention, there is a kinetic purifier which works passively and has no moving parts. (FIGS. 4 and 5) The present invention described herein, works without requiring electricity to process and purify large amounts of dirty air. FIG. 4 describes a cross section view of a kinetic air purifier structure. The kinetic air purifier structure is a tubular structure that serves as an air conduit for air purification process. The kinetic air purifier includes an air intake port (4.1), a protector screen (4.2), a first particle collection chamber (4.11), a first convex element (4.3), a first trapping element (4.4), a second particle collection chamber (4.12), a second convex element (4.5), a second trapping element (4.6), a micro-porous trapping element (4.7), and an air outlet port (4.8). The air intake port allows ingress of polluted air inside the air conduit. The air flows through the protector screen for screen large particles or insects. The air then enters the first particle collection chamber. The first particle collection chamber includes the first convex element which, in one example, can be a spherical object. The convex element is placed at a center of the passageway to obstruct the flow of the air. Obstruction results in reduction of width and height of the passageway. Air flowing through the smaller passageway gain velocity and reduces the pressure.

(16) Once the air flow is passed through the convex element, the air flows through the passageway with original width and height which results in reduced velocity and increased pressure. Change in velocity and the pressure causes turbulence in the first particle collection chamber, which subsequently results into separation of particulate matter from the air flow. The separated particulate matter is trapped inside the first particle collection chamber. The air further flows through the first trapping element which, in one example, can be a cotton fabric. The first trapping element entraps particulate matter with particles of smaller size relative to the particles separated at the convex element. The first particle collection chamber further includes a first chamber orifice (4.9) that allows access to the first particle collection chamber for cleaning purpose. Particles entrapped inside the chambers can be cleaned and the first trapping element can be changed. The second particle collection chamber is provided to perform same functionality such as the first particle collection chamber. The second particle collection chamber entraps particles of smaller size relative to the size of particles entrapped inside the first particle collection chamber. A second chamber orifice (4.10) allows access to the second particle collection chamber for cleaning purpose.

(17) In the present invention the dirty air is not aspirated; it is forced to circulate inside the purifier walls by the kinetic energy transferred from the vehicles where the purifier is mounted and in such a manner that the air carrying the particulate matter must flow through a separator chamber means. As reference, the kinetic energy is the same that allows the planes to fly. The movement of the vehicle transfers energy from the air as it is guided through the particle matter separator means and the toxic gasses adsorber means.

(18) FIG. 5 depicts a cross-sectional view of the kinetic air purifier (5). In a preferred embodiment an air intake port (5.1) provides an intake passageway for surrounding polluted air to ingress. A protector screen (5.2) prevents largest particles and insects, entered into the purifier with the air flow, from flowing further. The air then enters the first particle collection chamber. At the first particle collection chamber, the air passes over surface of a first convex element, dropping the particulate matter inside the chamber. The air then flows through a first trapping element where further particulate matter is adsorbed. The air enters into a second particle collection chamber. At the second particle collection chamber (5.12), the air passes over the surface of a second convex element (5.5), dropping the particles inside the second particle collection chamber (5.12). The air further flows through a second trapping element (5.6) which adsorbs remaining dirt particles. At this stage, air is clean and dirt free. If micro size elements, such as toxic gases, are still present in the air, such elements are adsorbed by a micro-porous trapping element (5.7) when the air passes through the last element of the kinetic air purifier. The clean, dirt free, and toxic element free air exists the purifier through an air outlet port (5.8).

(19) As contaminated air enters the kinetic air purifier through the air intake port (4.1), the particles of matter floating on said air are separated from the gaseous elements through at least one means that apply three well-known physical effects.

(20) The first is the Bernoulli Principle which holds that the pressure in a stream of fluid is reduced as the speed of the flow is increased. This principle is applied in an advantageous manner in the new invention through the application of the Venturi effect which holds that the pressure in the air decreases as the velocity of the air increases as it passes through a smaller section area in the air passways.

(21) As the dirty air moves within a closed space passway and that space then decreases its width and height, the speed of the air increases and thus it reduces its pressure. FIG. 4, element 4.3

(22) The reduction of the passways is achieved by suspending at least one convex or spherical reducer element at the center of the air passways section (FIG. 4, elements 4.3 and 4.5). The spherical surface of the reducer triggers a third kinetic energy effect called Coanda which is the tendency of a fluid let to stay attached to a convex surface.

(23) The dirty air circulates around the convex surface of the convex element following closely its surface at the same time that the passway first reduces its width and then expands again. (FIG. 7). The volume of air is thus divided as it passes through the smaller spaces around the reducer means and the air accelerates its speed and loses pressure at the same time (FIG. 8).

(24) As the dirty air goes around the convex element, the air slows its speed again as the passways means expand and the particles of matter are carried by the fluid at different speeds from different angles around the convex element. At the center of the back of the convex element the crosscurrents cause turbulence. The turbulence is created in the central point of the rear part of the convex element because the air advances on all sides of the sphere except in the back central part of the convex element. This turbulence causes the air to disperse and separate the particles of matter from the gaseous elements. (FIG. 9)

(25) The particles of toxic matter, heavier than air, lose the support of the pressure-less air current and fall due to the force of gravity. They are deposited in the bed of the first and second particle collection chambers (FIG. 6).

(26) In a preferred embodiment, the kinetic air purifier repeats the same process in a second particle collection-chamber, to pick up the smaller particles that the first particle collection chamber may have missed. (FIG. 4 element 4.12)

(27) Furthermore, to insure the smaller particles which may have not fallen in the previous separation process, there is the second trapping element made out of multitude of individual fibers, such as cotton natural or synthetic, which allow the trapping of small particles without impending the flow of air. FIG. 4, element 4.6

(28) The cleaner, particle-less air continues its way to the micro-porous trapping element FIG. 4, element 4.7.

(29) The micro-porous trapping element is composed of at least one means of micro-porous element, either natural such as activated vegetal carbon from coconut shell, or a synthetic material composed of micro-porous where elements such as acidic toxic compounds, acetates, and organic chemicals are adsorbed. (FIG. 9)

(30) Thus, the present and original invention called Kinetic Air Purifier, is an economical and feasible option to implement in all urban areas to clean the smog out of the sky by purifying massive amounts of dirty air without using a penny of electricity and without having to use and change filters.

(31) The passive operation of the kinetic air purifier allows the accumulation and periodic collection of the toxic particles that accumulate in the first and second particle collection chamber. (FIG. 6) without filters to replace. The chamber(s) are opened periodically, and the particles are aspirated safely. The micro-porous trapping element are changed periodically as its micro-porous get saturated. The micro-porous trapping element are reconstituted and reused.
