Embodiment Construction

[0073] When the automobile is running, the electromagnet 3 is energized to generate suction, which works together with the locking push rod 18 to compress the front air chamber 2, filter paper 5, sealing material 14 and sealing ring 15. Automobile exhaust enters the front air chamber 2 from the intake pipe 1, is filtered through the filter paper 5, enters the rear air chamber 22 after passing through the sealed telescopic tube 21, and flows out from the exhaust pipe 23. After the filter paper has been used for a period of time, the pores on the filter paper are blocked by particulate matter, which reduces the ventilation capacity of the filter paper, which will cause the air pressure in the front air chamber 2 to increase. The air pressure sensor 25 in the current air chamber 2 monitors that the air pressure in the front air chamber rises to a certain level P 0 , the signal is transmitted to the main control computer 24, and the main control computer judges that the current fi...

Abstract

An active filtering system for automobile exhaust particle emissions comprises an exhaust circulation system A, a filtering paper supply system B, a filtering paper recycling system C, a sealing system D, a locking system E, a control system F and a filtering paper set standby system G. The active filtering system is directly installed on an automobile and controls atmospheric particle pollutants from the source. According to the active filtering system for the automobile exhaust particle emissions, filtering paper with different filtering capacities is selected, control over the automobile exhaust particle emissions is achieved in the mode of various standards, and the control standards are easy to implement; real-time information interaction is conducted between the active filtering system and a driver through a master control computer, emission of automobile exhaust particles can be controlled from the source, and atmospheric pollution is effectively reduced; and the influence on the existing automobile structure layout is small, installation is easy, and using and maintenance are convenient.

Description

technical field [0001] The invention provides an active filtering system for particulate emissions of automobile exhaust, in particular to an active filtering system for particulate emissions in automobile exhaust, belonging to the technical field of automobile exhaust purification. Background technique [0002] With the development of economy and society, the automobile industry is developing rapidly, and the exhaust gas produced by automobiles in operation is an important source of urban air pollution. Particulate matter (PM) in vehicle exhaust is one of the most important pollution sources that constitute urban smog. The composition of particulate matter in automobile exhaust is complex and has strong adsorption capacity, which can adsorb various metal dust, strong carcinogen benzopyrene and pathogenic microorganisms. Automobile exhaust particles enter the lungs of the human body with breathing, and stay in different parts of the respiratory tract through collision, diff...
