DETAILED DESCRIPTION

A multipurpose air pollution and heat reducing device is herein described with numerous specific details so as to provide a complete understanding of the invention. However these specific details are exemplary details and should not be treated as the limitation to the scope of the invention. Throughout this specification the word “comprise” or variations such as “comprises or comprising”, will be understood to imply the inclusions of a stated element, integer or step, or group of elements, integers or steps, but not the exclusions of any other element, integer or step or group of elements, integers or steps.

Referring to the drawing, FIG. 1 shows a multipurpose air pollution & heat reducing device. The pollution reducing device comprises a tank 1 of any shape and size to suit the requirement and is adapted to be secured with a stand 2 provided for securing the device with the vehicle and/or any other pollution generating device, engine or chimney. Pollution reducing liquid 3 is provided in the tank 1 for filtration purposes. At least one layer of pebbles 4 is provided inside the tank 1 at its bottom. The layer of the pebbles 4 acts like a filter and is provided for filtering of the exhaust, having pollutants entrapped therein. At least one inlet tube 5 passing through the bottom of the tank is disposed in the tank 1 for allowing entry of the exhaust in the tank 1. The inlet tube 5 is disposed in the tank 1 such that the open end of the tube remains above liquid level in the tank 1. An inverted tube 6 is provided over the inlet tube 5 such that to discharge the exhaust with pollutants, received from a vehicle/industry and/or an engine or chimney near the bottom end of the tank 1 through the layer of pebbles 4. The inverted tube 6 is secured to the inner surface of the tank 1. The exhaust with pollutants is to pass through the filtering liquid 3 filled in the tank 1 and then it passes through a filter layers of pebbles 4 disposed in the tank 1. An outlet 7 is provided near the top end of the tank 1 for the exit of the filtered/purified exhaust/smoke/air.

The inverted tube 6 has perforation 8 near the lower end thereof such that to allow passage of the exhaust there through into the tank 1 having liquid 3 filled into the tank 1. The perforations 8 are provided in the inverted tube 6 at lower end and till the height up to which the pebbles 4 are filled in the tank 1. The perforations 8 are covered with a gauze filter 9. In one embodiment plurality of layers of the pebbles 4, of different sizes, may be provided in the lower portion of the tank 1. According to an embodiment, plurality of inlet tubes 5 with corresponding inverted tubes 6 provided over the inlet tube 5 are provided as per the requirement of the user and to suit the heavy automobiles, engine or chimney.

A liquid filling tube 10 is disposed into the tank 1 through its top end to fill the liquid 2 into the tank 1 up to a level such that all the filters 4, gauze filter 9 and other fitters are soaked with the liquid 3. The liquid filling tube 10 passes through the top end of the tank 1 and is submerged into the liquid 3 provided in the tank. A lid 11 is provided at the top end of the liquid filling tube 10 so as to cover it in an air tight manner.

A liquid level indicator 12 is provided with the tank so as to maintain the level of the liquid with in the tank 1 by filling the liquid 3 as and when required. A liquid drainage valve 13 is provided at the bottom of the liquid level indicator 12 to drain out the contaminated liquid 3 from the tank 1. A cover 14 is provided over the open top end of the level indicator 12. Fresh liquid 3 is filled in the tank 1 as and when required.

In one embodiment bottom end of the inlet tube 5 is connected to a manifold (not shown) such that to connect the inlet tube 5 with a hose pipe (not shown) being connected with the exhaust port (not shown) of a heavy vehicle, engine or chimney.

According to an embodiment, at least one layer of another gauze filter 15 is disposed in the tank 1 above the liquid 3 level. According to another embodiment, plurality of gauze filter 15 layers are provided above the liquid 3 level and supported on the supports 16.

The filter liquid comprises a liquid, for example, water or coolant capable to absorb the pollutants entrapped in the exhaust. Thus the liquid absorbs the suspended impurities present in the exhaust and also reduces the heat and the noise. The liquid also absorb dissolved harmful gases or particles, for example, Carbon monoxide or any other gases, present in the exhaust.

In one embodiment, a suction device, for example, an exhaust fan or blower (not shown) is provided with the inlet tube 5 or with the outlet 7 so as to create the pressure difference as the device works on the principal of pressure difference at the inlet tube 5 and the outlet 7 of the device.

The device is mounted at the exhaust outlet of the vehicle, automobile, chimney or anywhere where the pollution is required to be reduced. The exhaust with pollutants enter into the tank 1 of the device through the inlet tube 5, inverted tube 6 and then it passes through the gauze filter 9 to pass thorough the liquid 3 contained in the tank 1. Thus, the exhaust passes through a zig zag passage and through various filters i.e. pebble 4 filter, gauze filter 9, liquid 3 and again another gauze filters 15 and gets filtered. Thus the clean exhaust comes out of the device. In fact the exhaust first moves up in the inlet tube 5 and then moves down and passes through the liquid 3 in the inverted tube 6. The exhaust then enters into the filter layer of pebbles 4 through the perforation 8 provided at the bottom end of the inverted tube 6 and having a gauze filter 9 provided around the perforations 8. The exhaust then passes through liquid filter 3 and again through the gauze filters 15 to move upward before coming out as filtered/clean exhaust.

It has been noticed that by using this device pollution level reduces in the following manner;

• • Particles emitted from the burned fuel 70-80%
  • Air Pollution 60-90%
  • Green House Gases 60-70%
  • Noise Pollution 70-80%
  • Heat Reduction in Exhaust Gases 60-70%
