Problems solved by technology

Since the device uses a traditional filter membrane, the capture and filtration effect is poor for PM2.5 particles with small diameters
Chinese patents (application numbers: 201310137162.5 and 201310137165.9) propose a device for water atomization to remove particulate matter in automobile exhaust, using MRM membrane (molecular resonance membrane) to generate negative ions in water, water mist containing negative ions and gas in automobile exhaust , particulate matter and other reactions, so as to achieve the purpose of purifying exhaust gas, but this kind of device is large in size, low in purification ef

Abstract

The invention discloses a device for removing PM2.5 particles in automobile exhaust and a use method thereof. The device comprises a pipe, a high-voltage bag, a liquid storage box, a trace booster pump and an electrostatic spraying device. The pipe is provided with a gas inlet and a gas outlet, the gas inlet can be connected with an automobile exhaust emission pipe, and the caliber of the gas inlet is smaller than the inner diameter of the pipe. The gas outlet is connected with the pipe through a screw joint, and can be dismounted freely. A folding type filter membrane and an ash bucket are arranged on the gas outlet. An automobile storage battery can be used for power supply, the voltage is raised to 5 KV to 12 KV through the high-voltage bag, then chitosan aqueous solutions are jet into charged chitosan and other polymer nanofibers/particles by the electrostatic spraying device through electric field force, and therefore the PM2.5 particles, a little heavy metal elements and other harmful substances in the automobile exhaust and are adsorbed, and the aim of purifying the automobile exhaust is achieved.

Description

technical field [0001] The invention relates to an automobile tail gas purification device, in particular to a device for eliminating PM2.5 particles in the automobile tail gas. Background technique [0002] In recent years, the problem of regional air pollution in my country has become increasingly serious, and the haze weather characterized by PM10 and PM2.5 particulate matter has become increasingly prominent, seriously affecting people's health and ecological security. In order to control smog pollution in a targeted manner, in early 2014 the Ministry of Environmental Protection issued the "Notice on Carrying out the First Stage Research on Source Analysis of Atmospheric Particulate Matter" (Huanban﹝2014﹞No. 7). The source analysis results of PM2.5 particles released by major cities show that automobile exhaust is one of the main sources of particulate matter, and with the increase in the number of automobiles, the proportion of automobile exhaust in the source of partic...
