Description
AIR PURIFYING WATER FILTER
Crosβ'Reference to Related Applications
This application claims priority to Israel Application No. 195395 filed 20th November, 2008, incorporated herein by reference in its entirety.
Field of the Invention
The present invention relates to the field of air purifying. Specifically, this invention relates to air purifying water filter.
Background of the Invention
Air pollution has become one of the modern society biggest problems. As society has grown more mobile, the number of vehicles on the roads has dramatically increased, producing exhaust air containing harmful particulars to the atmosphere and living beings.
Numerous industries such as automotive, wood products, laundry dryers, furniture manufactures, copper manufactures, aluminum products, cement manufactures, foundries, plastic producers, PVC producers, chemical material producers, stationary diesel and turbine generators, power plants, tanning, inks and printing, paper products, paper mills, transatlantic vessels, trains, refiners, rubber producers, medical plants, incinerators plants, kitchen chimneys, odor creating industries, and other industrial plants produce harmful particulates, such as volatile organic compounds (V.O.C.s), nitrous oxide compounds (NOx), sulphur (Sox), mercury, phosphor, and Carbone oxide compound (CO), thus, increasing the damage to the atmosphere and living beings.
Legislative efforts have established emission standards to control emission wherein these standards identify how much of a certain particulate may
enter the atmosphere from an exhaust air stream. Current and future compliance with such standards places a continuing demand on industry and creates an ongoing need to reduce, degrade, and eventual destroy pollutants in exhaust air stream in a cost effective manner.
A current air filtration for both commercial and residential applications is accomplished by passing the air through a mesh material that traps a large percentage of the particulate matter in the air. However, as the filter becomes clogged with the captured materials, the flow of air through the filter becomes more restricted, while the fans used to circulate the air have to work harder. Periodically, either the filter must be replaced with a new filter or it must be removed, cleaned, and reinstalled. Many filters cannot be cleaned and reused. Throw away filters contribute to the ever-growing waste disposal problem, but cleaning and reusing the filters tends to degrade the filters over time to a point of ruin.
Many methods and systems are currently utilized to reduce particulates from entering the atmosphere. Such methods and systems include, but are not limited to, scrubbers, incineration techniques, exposure to ultra violate light, mechanical filtering, electrostatic filtering, condensing heat exchangers, and etc. Even though many approaches are currently utilized to reduce harmful particulates, a certain amount of these harmful particulates still are released to the atmosphere. Therefore, a need exists to overcome the aforementioned drawbacks of the prior art.
It is an object of the invention to provide a filter that will dramatically reduce the amount of pollutants in exhaust air stream, prior to the air being released into the atmosphere, in a cost effective manner.
It is another object of the invention to provide an inexpensive filter that will be easy to maintain.
It is a further object of the invention to provide a simple, yet, multi-purpose filter that will be easy to . accommodate to vehicles, industrial plants, and power plants.
It is still another object of the invention to provide vehicles with a simple, easy to maintain, cost effective filter that will provide a free exhaust air stream, prevent the pressure in the exhaust system from increasing, and maintain the engine efficiency.
Summary of the Invention
The present invention relates to an air purifying water filter, which comprises: A. a tank, filled with water up to a predefined water line! an intake port, located at the lower part of said tank, wherein bubbles of contaminated air enters the tank at said intake port and bubble upwards through the water toward said water line, and wherein contaminates are removed by contact of said bubbles with said water,' B. an output port, located at the upper part of said tank above said water line; C. means for splitting said bubbles of contaminated air into smaller bubbles, wherein said means are sunk in said water; D. means for scrubbing said bubbles of contaminated air against, wherein said means are sunk in said water; and E. means for bumping said bubbles of contaminated air into, wherein said means are sunk in said water.
Preferably, the means for splitting, bumping, and scrubbing said bubbles of contaminated air is a stainless steel net.

Detailed Description of Preferred Embodiments
Air filtration systems utilizing a liquid to aid in removal of particulate matter or toxic gases have been introduced for use in specific activities that generate high levels of polluted air.
FIG. 1 illustrates a current air filtration apparatus utilizing a liquid to aid in removal of harmful particulars. Contaminated air enters the apparatus at intake port 1, located at the lower part of tank 3, and bubbled 5 upwards through the water 6 toward water line 4. As the air bubbled 5 upward through the water 6, contaminates are removed by contact with the water 6. The purified air exits the apparatus at output port 2, located at the upper part of tank 3 above water line 4.
Harmful particulars are removed from the bubbles of contaminated air by contact with the water they are bubbling through. Therefore, increasing the bubbles surface area will provide a better contact with the water they are bubbling through and as a result much more harmful particulars will be removed from the bubbles.
Scrubbing the bubbles of contaminated air against rigid objects sunk in the water will further increase the removal of the harmful particulars from the bubbles.
Bumping the bubbles of contaminated air into obstacle will cause the harmful particulars trapped within the bubbles of contaminated air to move towards the bubbles surface area. Thus, more harmful particulars will have contact with the water they are bubbling through/will be scrubbed against rigid
objects sunk in the water. Thus, the removal of the harmful particulars from the bubbles will be further increased.
FIG. 2 illustrates an exemplary way of increasing the removal of the harmful particulars from bubble of contaminated aix 5 bubbling upward through hole 10 bored in a rigid body 9 sunk in water 6. First, a bubble of contaminated air 5 is scrubbed against the walls of hole 10, thus, increasing the release of harmful particulars to water 6. Wherein the diameter of hole 10 is Rl. Then, the bubble of contaminated air 5 is bumped into obstacle 11, causing the harmful particulars trapped within bubble 5 of contaminated air to move towards the bubbles surface area. Thus, more harmful particulars will have contact with water 6 they are bubbling through, and consequently the removal of the harmful particulars from the bubbles will be further increased. The bubble of contaminated air 5 is than squeezed into hole 8 having diameter R2, wherein R2 is smaller than Rl. Consequently the bubble of contaminated air 5 is divided into N smaller bubbles 7 of diameter R2.
Vl is the volume of a bubble having diameter of Rl, where
V2 is the volume of a bubble having diameter of R2, where
γ = π '^ 2 3
Dividing the volume of a bubble having diameter of Rl into the volume of a bubble having diameter of R2 produces the number N of smaller bubbles 7 having diameter R2, where N=VW2=CR1/2)Λ3/CR2/2)A3
C is the ratio between the comprehensive surface area of N bubbles 7 of diameter K2 and the surface area of a bubble having diameter of Rl, where
Q = R2 _ ^l π - R^ R2
Since Rl is bigger than R2 the comprehensive surface area of N bubbles 7 of diameter R2 is bigger than the surface area of bubble 5. Thus, more harmful particulars will have contact with water 6 they are bubbling through, and consequently the removal of the harmful particulars from the bubbles will be further increased.
The bubbles of contaminated air 7 are scrubbed against the walls of hole 8, releasing harmful particulars to water 6. The bubbles are than bubbled upwards through the water 6 toward water line 4.
FIG. 3 illustrates a cross-section illustration of an air purifying water filter comprising a split intake port. Contaminated air enters the air purifying water filter at intake port 1, which split into three identical, smaller pipes 12, 13, 14. The three identical pipes 12, 13, 14 enter the lower part of tank 3. As a result, the contaminated air bubbles 5 upwards in small bubbles having a big comprehensive surface area. As the air bubbled 5 upward through the water 6 toward water line 4, contaminates are removed by contact with the water 6. Since intake port 1 was split into pipes 12, 13, 14 the comprehensive surface area of bubbles 5 is bigger. Thus, more harmful particulars will have contact with water 6 they are bubbling through, and consequently the
removal of the harmful particulars from the bubbles 5 will be increased. The purified air exits the apparatus at output port 2. Corks 15 and 16 are used to empty the dirty water and refill fresh water respectively.
FIG. 4 illustrates a cross-section illustration of an air purifying water filter comprising a perforated surface for secondary purification. A bubble of contaminated air 5 enters the air purifying water filter at intake port 1. The contaminated air 5 bubbles upwards in the water 4 toward a perforated surface 17. As the bubble of contaminated air 5 bubbles upward through the water 6, contaminates are removed by contact with the water 6. The bubble of contaminated air 5 is than bumped into the perforated surface 17, causing the harmful particulars trapped within bubble 5 of contaminated air to move towards the bubbles surface area. Thus, more harmful particulars will have contact with water 6 they are bubbling through, and consequently the removal of the harmful particulars from the bubbles will be further increased. The bubble of contaminated aix 5 is than squeezed into hole 18, bored in perforated surface 17, having diameter R3, wherein R3 is bigger than the diameter of bubble of contaminated air 5. Consequently the bubble of contaminated air 5 is divided into smaller bubbles 7 of diameter R3 having comprehensive surface area which is bigger than the surface area of bubble 5. Thus, more harmful particulars will have contact with water 6 they are bubbling through, and consequently the removal of the harmful particulars from the bubbles will be further increased. The bubbles of contaminated air 7 are scrubbed against the walls of hole 18, releasing harmful particulars to water 6. The bubbles are than bubbled upwards through the water 6 toward water line 4. Corks 15 and 16 are used to empty the dirty water and refill fresh water respectively. Opening 19 is used to release extra water from tank 3.
FIG, 5 illustrates cross-section of an air purifying water filter comprising a split intake port and a perforated surface for secondary purification. Contaminated air enters the air purifying water filter at intake port 1, which split into three identical, smaller pipes 12, 13, 14. The three identical pipes 12, 13, 14 enter the lower part of tank 3. As a result, the contaminated air bubbles 5 upwards in small bubbles having a big comprehensive surface area. As the air bubbled 5 upward through the water 6, toward a perforated surface 17, contaminates are removed by contact with the water 6. Since intake port 1 was split into pipes 12, 13, 14 the comprehensive surface area of bubbles 5 is bigger. Thus, more harmful particulars will have contact with water 6 they are bubbling through, and consequently the removal of the harmful particulars from the bubbles 5 will be increased. The bubble of contaminated air 5 is than bumped into the perforated surface 17, causing the harmful particulars trapped within bubble 5 of contaminated air to move towards the bubbles surface area. Thus, more harmful particulars will have contact with water 6 they are bubbling through, and consequently the removal of the harmful particulars from the bubbles will be further increased. The bubble of contaminated air 5 is than squeezed into hole 18, bored in perforated surface 17, having diameter S3, wherein K,3 is bigger than the diameter of bubble of contaminated air 5. Consequently the bubble of contaminated air 5 is divided into smaller bubbles 7 of diameter R3 having comprehensive surface area which is bigger than the surface area of bubble 5. Thus, more harmful particulars will have contact with water 6 they are bubbling through, and consequently the removal of the harmful particulars from the bubbles will be further increased. The bubbles of contaminated air 7 are scrubbed against the walls of hole 18, releasing harmful particulars to water 6. The bubbles are than bubbled upwards through the water 6 toward water line 4. Corks 15 and 16 are used to empty the dirty water and refill fresh water respectively.
FIG. 6 illustrates a cross -section of an air purifying water filter comprising rigid geometric objects. A bubble of contaminated air 5 enters the air purifying water filter at intake port 1. The contaminated aix 5 bubbles upwards in the water 4 toward a net 21. As the bubble of contaminated air 5 bubbles upward through the water 6, contaminates are removed by contact with the water 6. The bubble of contaminated air 5 is than squeezed into hole 24 in net 21, having width which is bigger than the diameter of bubble of contaminated air 5. Consequently the bubble of contaminated air 5 is divided into smaller bubbles having comprehensive surface area which is bigger than the surface area of bubble 5. Thus, more harmful particulars will have contact with water 6 they are bubbling through, and consequently the removal of the harmful particulars from the bubbles will be further increased. The bubble of contaminated air 5 is than bumped into the rigid geometric objects 20, causing the harmful particulars trapped within the bubble of contaminated air to move towards the bubbles surface area. Thus, more harmful particulars will have contact with water 6 they are bubbling through, and consequently the removal of the harmful particulars from the bubbles will be further increased. Further, the bubbles of contaminated air are scrubbed against the rigid geometric objects 20, releasing harmful particulars to water 6. The bubbles are than bubbled upwards through the water 6 toward water line 4. Corks 15 and 16 are used to empty the dirty water and refill fresh water respectively. The contaminated water is being purified through water filter 22 by water pump 23.
FIG. 7 illustrates two possible ways of splitting a contaminated bubble of air.
FIG. 7(a) illustrates a cross -section of a turbine blade 25 comprising a brush 26 splitting a contaminated bubble of air 5. A bubble of contaminated air 5 is squeezed into hole 18, bored in perforated surface 17 while it is being
scrubbed by turbine blade 25 comprising a brush 26. Consequently the bubble of contaminated air 5 is divided into smaller bubbles having comprehensive surface area which is bigger than the surface area of bubble 5. Thus, more harmful particulars will have contact with water 6 they are bubbling through, and consequently the removal of the harmful particulars from the bubbles will be further increased.
FIG. 7(b) illustrates a cross-section of a rotating perforated surface 26 splitting a contaminated bubble of air 5. A bubble of contaminated air 5 is squeezed into hole 18, bored in perforated surface 17 while it is being scrubbed by a rotating perforated surface 26. Consequently the bubble of contaminated air 5 is divided into smaller bubbles having comprehensive surface area which is bigger than the surface area of bubble 5. Thus, more harmful particulars will have contact with water 6 they are bubbling through, and consequently the removal of the harmful particulars from the bubbles will be further increased. Thus, a perforated surface comprising large diameter holes can be used to produce small bubbles. Consequently, the probability of blocking the perforated surface holes will be lowered.
Although embodiments of the present invention have been described by way of illustration, it will be understood that the invention may be carried out with many variations, modifications, and adaptations, without departing from the scope of the claims.
