Abstract

The invention provides a stepping type particulate matter monitor utilizing a Beta ray method. The monitor comprises a mounting frame, a film rolling assembly, a clamping traction assembly and a sampling detection assembly, wherein the mounting frame has a sampling position and a detection position; the film rolling assembly comprises a first roller and a second roller; the clamping traction assembly comprises a clamping part which can be arranged between the first roller and the second roller in a reciprocating mode and is used for clamping and driving a filter membrane between the first roller and the second roller to ensure that the filter membrane does reciprocation motion between the sampling position and the detection position; the sampling detection assembly is used for correspondingly sampling and detecting the filter membrane when the filter membrane is clamped and driven by the clamping part to move to the sampling position and the detection position in the reciprocating mode. According to the stepping type particulate matter monitor utilizing the Beta ray method, the problem in the prior art that the filter membrane continuously deviates from the original direction until the filter membrane is broken and damaged caused by the factor that the deviation accumulative effect is easily caused by means of rolling grinding is solved.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring, in particular to a step-by-step Beta ray particle monitor. Background technique [0002] The Beta ray particle monitor is an instrument for real-time online monitoring of particulate matter in the air (including PM10, PM2. This instrument is equipped with a filter membrane that can be renewed according to a period, and a Beta ray source and a Beta ray detector are respectively arranged on the upper and lower sides of the filter membrane. As the sample collection proceeds, the mass of particulate matter collected on the filter membrane also increases, and the Beta ray intensity detected by the Beta ray detector will attenuate accordingly. Since the output signal of the Beta ray detector can directly reflect the mass change of the particles, the particle concentration during the sampling period can be obtained by analyzing the particle mass value of the Beta ray detector and combi...
