Abstract

The invention relates to a particle cutter and especially relates to a double-channel bypass-type air particle cutter. The double-channel bypass-type air particle cutter is characterized by comprising a shunting chamber (2), and a primary shunting device and a secondary shunting device arranged in the shunting chamber (2). The double-channel bypass-type air particle cutter has the advantages that 1, a design is reasonable; a structure is simple; and practical applicability is good; and 2, under the conditions of the same air source and the same power, two types of particles having different sizes can be collected respectively or simultaneously; a cost is saved; and air quality measure accuracy is improved.

Description

technical field [0001] The invention relates to a particulate matter cutter, in particular to a dual-path shunting type air particulate matter cutter. Background technique [0002] At present, environmental problems are more and more concerned by the government and the public. With the development of industrialization, gas emissions, including vehicle exhaust emissions, are becoming more and more serious. The monitoring of air quality, especially the monitoring of inhalable particulate matter, has been paid more and more attention. Most of our country currently uses PM10 data, and the public increasingly believes that PM2.5 can better reflect air quality indicators. However, some of the existing PM2.5 cutters cannot be effectively coupled with analytical instruments, and some have too high requirements, resulting in filtration. The excessive consumption of consumables such as membranes brings about the problem of increased costs. This affects the monitoring level of atmosp...
