Air pollution particle detection equipment

Abstract

The invention provides air pollution particle detection equipment which comprises a box body, a box door and a particle detector, wherein the box door is installed at the front end of the box body, aparticle sensor is installed on the outer surface of the upper end of the particle detector, the upper end of the particle sensor penetrates through the box body and extends to the upper side of the box body, strip-shaped plates are arranged on the left side and the right side of the box body, threaded blind holes are formed in the middle of the surfaces, close to the box body, of the strip-shapedplates, first round holes are formed in the left wall and the right wall in the box body correspondingly, connecting bolts are arranged in the first round holes, the connecting bolts are engaged in the threaded blind hole through threads, two fixing blocks are symmetrically fixed to the face, away from the box body, of each strip-shaped plate, a notch is formed in the front end surface of each fixing block, and a force bearing plate is fixed to the upper end of each strip-shaped plate. Compared with the prior art, the air pollution particle detection equipment has the following beneficial effects that standby dismounting of the box body is achieved when the fixing bolts are difficult to dismount due to corrosion and other causes, and floating objects such as a plastic bag are prevented from being attached to the particle sensor.

Description

technical field [0001] The invention relates to air pollution particle detection equipment, which belongs to the field of air detection equipment. Background technique [0002] Respirable particulate matter (PM10) persists in the ambient air for a long time and has a great impact on human health and atmospheric visibility. Some particulate matter comes from direct emissions from pollution sources, such as smokestacks and vehicles. Others are fine particles formed by the interaction of sulfur oxides, nitrogen oxides, volatile organic compounds, and other compounds in the ambient air. Their chemical and physical composition varies greatly depending on location, climate, and season of the year. Big. Respirable particulate matter usually comes from motor vehicles driving on unpaved or cemented roads, crushing and grinding of materials, and dust blown up by wind. [0003] At present, particle detectors are often arranged in the outdoor environment to detect the pollution parti...

Problems solved by technology

[0003] At present, particle detectors are often arranged in the outdoor environment to detect the pollution particles in the air, but the fixed structure on the box used to store the particle detector is directly welded to the box, and installed in the fixed structure on the box When the fixing bolts are difficult to disassemble due to corrosion and other reasons, it is necessary to disassemble the damaged parts, which is not conducive to the recycling and reuse of the box.
