Abstract

The invention provides a multi-channel air particulate matter sampler flow calibration switching device. A sampler comprises a top plate, a bottom plate and straight line guide rods connected with the top plate and the bottom plate, a cutter tray provided with N cutters and a filter membrane clamp tray provided with N filter membrane clamps are installed on the straight line guide rods in a sleeving mode, and an elbow clamp which can push the filter membrane clamp tray to make reciprocating motion in the vertical direction is further arranged on the bottom plate. The top plate is provided with air inlet nozzle slideways, a sliding plate which can slide along the top plate in the left-right direction is installed at the bottom of the top plate, and N sampling connection nozzles and N calibration connection nozzles are arranged on the sliding plate, wherein N is any integer ranging from two to eight. When the sampler is calibrated, the sliding plate is moved to switch air inlet nozzles, and then a calibration instrument is connected with a calibration flexible pipe, so that flow calibration can be conducted, flexible pipes on the air inlet nozzles are not needed to be pulled out, calibration operation steps are simplified, and convenience and rapidness are achieved.

Description

technical field [0001] The invention belongs to the field of air particle samplers, in particular to a multi-channel air particle sampler flow calibration switching device. Background technique [0002] With the frequent occurrence of dust storms and smog weather, the air pollution problem has attracted more and more people's attention. The detection of air quality is also particularly important. The monitoring, analysis and research of particulate matter in the air is the focus of current environmental protection work. The monitoring scope of air particulate matter mainly includes total suspended particulate matter TSP, inhalable particulate matter PM10 and fine particulate matter PM2.5. In order to analyze the composition of different particulate matter, parallel sampling of particulate matter in the ambient air at the same time period and at the same location is required. At this time, a multi-channel air particulate matter sampler is often used to divide the gas collect...
