Automobile tail gas purification system and purification method thereof

Abstract

The invention provides an automobile tail gas purification system and a purification method thereof. The automobile tail gas purification system comprises a purification box, a pressure increasing box, a purification liquid circulating device and a liquid level water replenishing device, wherein the purification box is provided with a purification liquid inlet, a waste liquid outlet, a tail gas inlet and a tail gas outlet; the tail gas inlet is lower than the tail gas outlet, the purification box is communicated with the pressure increasing box through micropores, the purification liquid circulating device is communicated with the purification box and the pressure increasing box, and the liquid level water replenishing device is used for replenishing water in the purification box. The tail gas inlet is arranged on an automobile exhaust pipe opening, the purification liquid circulating device is communicated with a water source, a purification liquid is added into the purification box, an automobile starts, tail gas enters the purification box, the purification liquid circulating device is opened, the purification liquid is conveyed to the pressure increasing box and then is sprayed in the purification box, the sprayed liquid wraps particulate matters in the tail gas and then falls back in the purification liquid, the purified tail gas is discharged from the tail gas outlet, and finally, the purification treatment is finished. The purification system provided by the invention has the advantages that the structure is simple, the cost is low, the purification operation is convenient, and the application prospect is good.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to an automobile exhaust purification system and a purification method thereof. Background technique [0002] Haze weather often occurs all over the country now. Haze weather has a great impact on human health. It is easy for people to suffer from diseases such as upper respiratory tract infection, bronchial asthma, lung cancer, conjunctivitis, and infantile rickets, which seriously affects people's physical and mental health. [0003] We know that the formation of smog is mainly due to excessive dust, sulfuric acid, nitric acid and other particles in the air, and these fine particles are mainly caused by automobile exhaust, factory exhaust emissions and other reasons. Therefore, reducing pollution sources and reducing air pollutants is the fundamental way to solve smog. [0004] The products currently on the market cannot solve the PM2.5 particles in the...
