Abstract

A visual system used in a particle trapping process of a diesel engine belongs to a visual device for directly observing the process of trapping particles in tail gas of the diesel engine in an online manner. An outlet, which guides in air, of a preheater is communicated with a main body section, a tail gas sampling heating tube which guides in the tail gas of the diesel engine is communicated with the main body section via a pipe, a gas outlet of the main body section is successively connected with a cooler, a dryer, a filter, a mass flowmeter and a vacuum pump, and an outlet of the vacuum pump is connected with evacuation tube; a gas inlet of the main body section is provided with a temperature sensor and a pressure sensor, the gas outlet of the main body section is also provided with a temperature sensor and a pressure sensor, and a thermocouple temperature sensor extends into a filtering medium in the main body section; and the main body section is provided with a visual window for observation of a visual instrument. The visual system can be used for directly observing a particle trapping process of various filtering media in an online manner under working conditions of various temperatures and various flows, and has the advantages of convenience in assembly and disassembly, reliable performances and the like.

Description

technical field [0001] The invention belongs to an automobile tail gas post-treatment system, in particular to a visualization system for directly observing the particle trapping process in diesel engine tail gas online. Background technique [0002] At present, energy saving and emission reduction has become a hot topic in the world, and automobiles are large energy consumers. Therefore, it is imperative to realize energy saving and emission reduction of automobiles. Various advanced engine technologies are applied to automobiles to reduce their fuel consumption rate and pollutant emissions. Among them, dieselization of automobiles is a feasible solution to realize energy saving of automobiles. The reason is: Compared with gasoline vehicles, diesel vehicles have better fuel economy and lower CO 2 Emissions, strong stability, large output power, etc., the CO produced by diesel vehicles with the same displacement 2 The amount can be more than 30% lower than that of gasoline...
