Problems solved by technology

In this process, the filter membrane needs to be precisely positioned, so the structure is complex, which is easy to cause paper feeding errors and inaccurate measurement
In addition, this detection method needs to move to the detection area after the enrichment is completed, and it is impossible to detect while enriching, and the timeliness is poor

Abstract

The invention discloses enriching and detecting equipment for particles. The equipment comprises a sampling chamber body; the sampling chamber body comprises a sampling chamber; a sampling filter membrane is arranged in the sampling chamber, and is used for dividing the sampling chamber into an air inlet chamber and an air outlet chamber; the air inlet chamber is provided with an air inlet, and the air outlet chamber is provided with an air outlet; a detecting device is also arranged in the sampling chamber; a detecting window of the detecting device is communicated with the are inlet chamber and / or the air outlet chamber, so that the particles enriched on the sampling filter membrane are detected and analyzed. According to the enriching and detecting equipment for particles of the invention embodiment, by arranging the sampling filter membrane and the detecting device in the sampling chamber, the enrichment and detection of the particles can be realized simultaneously; problems that particle sampling and enriching are separated, and real-time detection is impossible are solved; errors caused by the movement of the sampling filter membrane are eliminated; and the equipment can be applied in on-line monitoring of particles in gas.

Description

technical field [0001] The invention relates to the field of particle detection and monitoring, and more specifically, to a particle enrichment and detection device. Background technique [0002] At present, in the air field of environmental monitoring, especially in the field of particulate matter monitoring, the main monitoring item is the mass concentration of particulate matter, including online monitoring of TSP, PM10, and PM2.5. In a few areas, heavy metals in particulate matter are also monitored. On-line monitoring methods for particle mass concentration include β-ray method, oscillating balance method, light scattering method, etc.; for on-line monitoring of heavy metals in particles, X-ray fluorescence method and electrochemical method are mainly used. [0003] The oscillating balance method can realize real-time monitoring of particle concentration, but its maintenance cost is high, it is greatly affected by humidity, and a membrane dynamic measurement system must...
