The invention discloses a diesel engine black smoke catalytic agent filter system for a bus. The diesel engine black smoke catalytic agent filter system mainly comprises a circular-barrel-shaped gas inlet cavity, a circular-barrel-shaped diesel engine black smoke catalytic agent filter element and a circular-barrel-shaped exhaust cavity. A gas inlet is formed in one end of the circular-barrel-shaped gas inlet cavity. The other end of the circular-barrel-shaped gas inlet cavity is connected with one end of a circular-barrel-shaped diesel engine black smoke catalytic agent filter in an abutting mode. The other end of the circular-barrel-shaped diesel engine black smoke catalytic agent filter is connected with the circular-barrel-shaped exhaust cavity in an abutting mode. An exhaust opening is formed in the circular-barrel-shaped exhaust cavity. The circular-barrel-shaped gas inlet cavity is connected with the circular-barrel-shaped diesel engine black smoke catalytic agent filter through a clamping hoop. A pressure difference and temperature sensor is arranged on the circular-barrel-shaped diesel engine black smoke catalytic agent filter. Due to the structure, the system is used for diesel engine waste gas treatment for the bus and is arranged at an engine exhaust port to replace a silencer, and the system integrates four functions that carbon monoxide (CO), hydrocarbon (HC) and black smoke particles (PM) in waste gas are treated and partial silencing is achieved.
Description
technical field [0001] The invention relates to a motor vehicle tail gas treatment device, in particular to a diesel engine black smoke catalyst filter system for buses. Background technique [0002] The State Intellectual Property Office published the publication number CN201625490U on November 10, 2010, and the patent name is an invention patent for an exhaust gas purification device. The technical solution of the patent includes a gas storage tank for collecting exhaust gas, and a The exhaust gas vacuum pump in the air storage tank is provided with an activated carbon filter for filtering the exhaust gas between the air storage tank and the vacuum pump, and a water filter for filtering the exhaust gas is provided at the exhaust port of the vacuum pump. The exhaust gas from the gas storage tank is filtered by the activated carbon filter and then enters the vacuum pump. The volatile substances in the raw materials are absorbed by the activated carbon, and the volatile gas e...
