Black smoke catcher used for diesel engine

Abstract

The invention discloses a black smoke catcher used for a diesel engine. The diesel engine can generate a large amount of black smoke at the cold starting moment and during high-load operation, however, no good solution exists at present. The black smoke catcher used for the diesel engine is composed of a catcher cylinder body, a black smoke particle collecting end connected with the lower end of the catcher cylinder body and a catcher gas outlet end connected with the upper end of the catcher cylinder body. A cylinder of the catcher cylinder body is provided with a gas inlet, a gas inlet baffle enabling air flows to be dispersed is fixed onto the inner wall of the cylinder, a filter element is arranged in the cylinder and an electromagnetic pulse pneumatic control valve is further fixed onto the inner wall of the cylinder. Black smoke tail gas generated during operation of the diesel engine is caught through filtering of the filter element and back flushing of the electromagnetic pulse control valve, and the black smoke removing rate reaches over ninety percent. The black smoke catcher used for the diesel engine has the advantages of being compact in structure, resistant to high temperature, easy to tailor, firm, durable and the like, increases the black smoke capturing rate, further reduces exhausting backpressure, is convenient to install and replace, and reduces the use cost and the maintenance cost.

Description

technical field [0001] The invention relates to a black smoke trap for a diesel engine, and belongs to the technical field of manufacturing engine exhaust gas catalytic converters. Background technique [0002] In recent years, due to the deterioration of air quality, the frequency of smog has increased and the damage has become more serious. Among them, inhalable particulate PM2.5 has become the focus of public attention, making people pay more and more attention to air quality. At present, according to relevant statistical data, more than 35% of the polluted air is caused by vehicle exhaust. Urban buses are in poor condition due to frequent starting and parking, and emit a large amount of black smoke when starting at platforms and intersections, resulting in urban air pollution. At the same time, it seriously affects the physical and mental health of residents. Diesel engines and generators produce a lot of black smoke at the moment of cold start and under heavy load con...
