Embodiment Construction
[0008] The specific structure, working process and best implementation mode of the present invention will be further described below in conjunction with the accompanying drawings.
[0009] Fig. 1 is a structural schematic diagram of a device for removing inhalable particulate matter from automobile exhaust provided by the present invention. The device is composed of a group of thermophoresis working sections 1 and upper and lower cascade boxes 2 arranged in parallel; The inlet and outlet of the two parallel thermophoresis working sections are connected; the outer wall of the thermophoresis working section is cooled by cold air to maintain a lower wall temperature of the tube wall, and the inhalable particles in the high-temperature exhaust gas in the tube will be heated Deposited on the wall of the thermophoresis working tube under the action of swimming. Exhaust gas containing respirable particles enters the first-stage thermophoresis working section. Under the action of the...

A device used for removing particle matter capable of being inhaled in vehicle tail gas belongs to a removing device of superfine particles in vehicle tail gas. Said device consists of a group of thermophoresis working sections and upper and lower levels headers which are arranged in parallel, wherein said thermophoresis working sections are set between the upper and lower levels headers, with surfaces at the same side of each header being respectively connected with the inlet and outlet of adjacent two stage parallel thermophoresis working sections. By adopting freezing air outside vehicles to cool the thermophoresis working section pipe walls, affected by the thermophoresis effect caused by the temperature difference, the particle matter capable of being inhaled contained in tail gas will deposit at the tubular inner wall surface of the thermophoresis working sections. In accordance with the present invention, by taking advantage of the non-thorough progression flowing effect, affected by the thermophoresis effect, the thermophoresis deposition efficiency is gradually increased at each stage, and a higher total deposition efficiency is achieved finally. The invention has the advantages of low fabrication and operating cost, convenient embodyment and simple control; can realize highly effective removal of particle matter capable of being inhaled at different installation conditions.
Description
technical field [0001] The invention relates to a device for removing inhalable particulate matter from automobile exhaust, specifically, the cold air outside the automobile is used to cool the pipe wall passing through the exhaust gas, and the inhalable particulate matter contained in the exhaust gas is heated by temperature difference. Swimming effect, will be deposited on the inner wall surface of the working pipe section, a new type of device to realize the removal of inhalable particulate matter in automobile exhaust gas, belonging to the technical field of automobile exhaust gas purification or dust removal. Background technique [0002] With the increasing number of automobiles in big cities, inhalable particulate matter (PM2.5) in automobile exhaust has risen to become one of the main sources of environmental pollution. Its removal has also become an international problem. Some existing exhaust gas purifiers use adsorption or chemical reaction principles to remove h...
