Abstract

The invention relates to detection equipment and in particular discloses dust concentration detection equipment. The dust concentration detection equipment comprises a compression part and a detectionpart, wherein the compression part comprises a barrel body, and a second piston, a separation plate and a first piston which are arranged in the barrel body from top to bottom; the separation plate is fixed to the barrel body; the two pistons are connected through a connecting rod; the first piston is connected with the connecting rod through a unidirectional bearing; the second piston is fixed to the connecting rod; a spiral flange and a spiral groove, which are mutually matched, are arranged on the connecting rod and the separation plate; the barrel body is made of a transparent material; adetection region is located below the first piston; a vacuum region is formed between the first piston and the separation plate; a water storage region is located above the second piston; a water flow channel is arranged in the connecting rod; the water flow channel comprises an entrance section, a throat section and a diffusion section; the diffusion section is internally provided with a check valve; a suction hole is formed in the edge of the first piston and a plugging block capable of plugging the suction hole is arranged; the compression part comprises a laser transmission end and a laser receiving end, which are arranged at two sides of the detection region. According to the equipment provided by the invention, gas is compressed so that the concentration of dust in a space is improved and the detection precision is improved.

Description

technical field [0001] The invention relates to detection equipment, in particular to a dust concentration detection equipment. Background technique [0002] Dust concentration meters can be divided into environmental dust meters and pipeline dust meters according to different application fields. [0003] Ambient Dust Meters are used to measure dust or particulate matter concentrations in open spaces. It can be widely used in various industries for online real-time dust concentration monitoring of factories, working environments, work spaces, offices, outdoor spaces, etc., as well as monitoring of dust concentration in special industrial working environments such as mines and underground coal mines. [0004] The pipeline dust meter can be used to monitor the trend change of dust concentration in various flue gas pipelines, monitor the dust emission of fixed pollution sources, and control the conveying process and proportion of solid powder. Duct dust meters are usually ins...
