Description

[0001] 1. Technical field: Automobile exhaust gas purification system is a new technical solution and equipment designed for automobile internal combustion engines (including gasoline engines and diesel engines) powered by fossil energy to eliminate exhaust gas generated by automobile combustion.

[0002] 2. Background technology: Automobile technology has brought great convenience and efficiency to people's lives and production. Oil and natural gas are still one of the main sources of power. In order to solve the contradiction between use and pollution, an exhaust gas purification system is designed. For many years, people have used a lot of methods to solve this contradiction: such as changing the carburetor to electronic injection technology, changing single-point injection to multi-point injection, improving the gas port injection to cylinder direct injection, changing the oxygen sensor single-loop control to closed-loop control, and using three-way catalytic technology at the same time, greatly reducing air pollution and achieving great results. But these are not enough. There are still many harmful substances such as sulfur dioxide, nitrogen dioxide, carbon particles, and other particles that cannot be effectively removed. These are the main pollutants that form haze and acid rain, and the particles they emit are the main source of PM2.5 particles in the air. We know that even a new car with the best technology can produce particulate matter, sulfur dioxide, nitrogen dioxide and other harmful substances due to fuel impurities. As the engine's function declines, more harmful substances will be discharged into the air. In response to these situations, methods and equipment to eliminate these substances have been invented and designed. Compared with the exhaust purification system of gasoline vehicles, the automobile exhaust purification system has added 4 layers of stainless steel wire mesh, an antifreeze water storage tank, a 5-degree water temperature control switch, a 100-degree muffler temperature control switch, a water level switch, a water level alarm, a water pipe and an electronic switch, a pressure balance pipe and an electronic switch, which increase the scope of application and filtering effect.

[0003] 3. Invention content: Automobile exhaust gas purification system, Figure 1 It is a device used to purify particulate matter, sulfur dioxide and nitrogen dioxide in automobile exhaust. Water is added to the exhaust pipe to vaporize the water through the high temperature of the exhaust gas. The water in the automobile exhaust gas is cooled and shrunk to make it drip out. Water molecules will adhere to the particulate matter, and gas molecules that can dissolve in water will dissolve in water. In view of the fact that most automobile exhaust pipes are very long, fins can be installed in the middle to cool them down naturally. The water in the exhaust gas and the added water form saturated water vapor at high temperature and mix with the particulate matter and gas in the exhaust gas. 4 layers of 18 mesh, 1 layer of 100 mesh and 1 layer of 150 mesh stainless steel wire mesh are installed at the tail of the exhaust pipe. The 150-mesh stainless steel wire mesh is directly in contact with the outside air, forming a hot and cold intersection surface inside and outside the stainless steel wire mesh, forming an intersection of hot and cold air currents, so that water vapor quickly condenses on the stainless steel wire mesh, forming a water curtain on the stainless steel wire mesh. The water curtain can stick to harmful substances such as particulate matter and gas molecules, and is also suitable for meshes of other materials. According to the above method, a set of automobile exhaust purification system is designed. Figure 1The following is a structural diagram of the installation position and connection relationship of each part.
