The invention provides a purifying and muffling device for automobile exhaust. The purifying and muffling device comprises an outer barrel, and air supply units, a catalyzing unit, a muffling unit and a purifying unit which are arranged in the outer barrel in sequence. The air supply units are positioned at one end, close to an automobile exhaust pipe, of the outer barrel. The purifying unit comprises a lime water filtering layer and adsorption layers arranged at two ends of the lime water filtering layer. A molecular sieve catalyst is arranged in the catalyzing unit. The muffling unit comprises a windshield and a U-shaped muffling pipe arranged on one side, facing an exhaust port, of the windshield. A plurality of muffling holes are formed in the wall of the U-shaped muffling pipe. The air supply units are arranged in front of the catalyzing unit, and when fresh air is supplied, the activity of the catalyst can be improved, and the catalytic efficiency of the catalyst in the catalyzing unit is improved greatly. Automobile exhaust is catalyzed and purified for multiple times, so that the content of carbon dioxide and particle dust pollutants in exhaust is reduced greatly, and pollution to environment is effectively avoided, and through combination with the muffling effect of the U-shaped muffling pipe, purifying and muffling of exhaust are realized.
Description
technical field [0001] The invention belongs to the technical field of exhaust gas purification and environmental protection equipment, in particular to an automobile exhaust gas purification muffler. Background technique [0002] In recent years, with the development of the economy, the ownership of automobiles in our country has increased dramatically. Vehicle exhaust emissions have become the fastest growing source of air pollution. The pollution of vehicle emissions has become one of the major problems in the urban environment. Although there are many technologies for controlling vehicle exhaust emissions, they still cannot solve the problem of pollution particles emitted by vehicles in actual use, and the long-term existence of smog in our country urgently needs to solve the pollution problem of vehicle exhaust. Generally, the requirements for exhaust gas purification catalysts include: high activity, large exhaust gas emissions, and limited installation space for cat...
