The present invention is a two-in-one invention of automobile noise reduction and exhaust gas purification. The automobile exhaust noise reduction purifier is divided into three parts. The first part is to cool down the high-temperature expansion body discharged from the car. The second part is the water cooling sand filter, the secondary filter chamber, and the third part is the water cooling carbon filter exhaust gas filtration.

The first part is divided into three cooling chambers

1. In the copper tube cooling room, because the copper tube dissipates heat quickly, straight tubes or coiled tubes with a diameter of 8 to 12 mm can be used for heat dissipation as required. 2. The copper straight tube spiral radiator is used for heat dissipation, and the temperature of the gas after heat dissipation is about 90°C. 3. In the water cooling room, put the copper straight tube spiral radiator into the water to cool down and then cool down again. After cooling through the water, the temperature is 70-80°C.

The second part of the water cooling sand filter

1. Water cooling After the first part of cooling 70 ~ 80 ℃, the temperature of the exhaust gas entering the water and sand net is below 50 ℃. 2. Filter out the harmful substances in the exhaust gas through water and multi-layer sand nets to make them precipitate in the water. 3. The secondary filtration is to pump the particulate matter deposited in the water into the second chamber for filtration, so that the first chamber maintains a certain degree of cleanliness, and the sediment in the second chamber can pass through the bottom outlet of the liquid filtration chamber 6-3 Take it out at any time to prolong the service life of the invention. The sand net of the present invention adopts the fine sand and gravel raw material of 60 meshes or more to press into a cuboid, cylinder or cylinder shape, and passes through the gaps between the sand grains to effectively block and filter the tiny particles in the exhaust gas.

The third part of water and activated carbon net absorbs the peculiar smell in the exhaust gas through water and then through activated carbon net to absorb carbon dioxide out of the sand net for filtration.

The above three parts, the first part is the cooling system, which makes the expansion gas discharged from the engine shrink, so that the metal and non-metal oxide particles in the gas gather, the second part is filtered by multi-layer water and sand net, after the first part is cooled After the aggregated particles enter the water, they are in a semi-dissolved state, which increases the specific gravity, which leads to an increase in the sedimentation rate and improves the filtration effect. Sand filter: 1. The air bubbles entering the exhaust gas of the multi-layer network are broken into small air bubbles, which increases the gas-liquid contact area. It is beneficial to improve the filtering effect. 2. The sand net filter can also slow down the rising speed of the bubbles and fully dissolve and absorb the soluble matter in the bubbles. 3. The sand net has strong air permeability and good filterability, and can filter out tiny particles. When the amount of water in the water-cooling cooling system 3, the dust removal system 4 and the odor filtering system 5 decreases during the operation of the present invention, water can be replenished through the water inlet pipelines at the top respectively.

Water and Activated Carbon Mesh

The unabsorbed peculiar smell coming out of the second part enters the third part to be dissolved by water, then adsorbed by the activated carbon net, and finally discharges the clean gas.

car muffler

The above-mentioned first part of the gas is lowered to 70-80°C, the second part is lowered to below 50°C, and then the third part is slowly lowered to 20-40°C, which is equivalent to the air temperature of the engine inlet, thereby effectively improving the noise reduction effect.
