Embodiment Construction

[0030] The present invention consists of a housing, a dust sample separation part for separating gas particles, a dust sample collection part for collecting separated particles, a paper tape transmission part for ensuring continuous operation of the system, and a device for determining the quality and concentration of collected particles. The dust sample detection part is composed of a constant flow part used to control the constant flow of the system inlet.

[0031] As shown in the figure, the dust sample separation part is composed of cutters 10 for separating different particle sizes, namely TSP, PM 2.5 and PM 10 Three kinds of cutters, the lower end of the cutter 10 is connected with the sampling pipe 20 of the dust sample collection part by a straight plug-in hard connection, and is sealed with a double O-ring embedded in the groove of the cutter base to prevent air leakage.

[0032] As shown in the figure, the dust sample collection part is composed of a sampling tube 2...

Abstract

An automatic particle monitor belongs to the technical field of atmosphere monitoring equipment and is used for monitoring the concentration of particles in atmosphere. The technical scheme includes that the automatic particle monitor consists of a dust sample separating portion, a dust sample collecting portion, a paper tape conveying portion, a dust sample detecting portion and a constant-flow portion, a cutter component of the dust sample separating portion is in direct-insertion type hard connection with a sampling tube of the dust sample collecting portion, a pipeline adapter connected to the lower end of the sampling tube is hermetically connected with a shell, the dust sample detecting portion is embedded in the dust sample collecting portion, a glass fiber filter tape of the paper tape conveying portion penetrates between a direct-proportion counter of the dust sample detecting portion and a radioactive source, a plurality of sensors and an adjusting valve of the constant-flow portion are connected onto a pipeline at the rear of an air outlet tube of the dust sample collecting portion, and the adjusting valve is connected with an external pump. The automatic particle monitor has the advantages that the automatic particle monitor is simple in structure, long in operating cycle and convenient in maintenance, monitors data fast and accurately, realizes real-time transmission and control with a center control station, does not need reagent, is pollution-free, and the like.

Description

technical field [0001] The invention relates to an automatic monitoring device for atmospheric particulate matter, in particular to an online monitoring device capable of continuously collecting particulate matter in the atmospheric environment online and accurately measuring the concentration of the particulate matter, and belongs to the technical field of automatic monitoring equipment for ambient air. technical background [0002] Atmospheric particulate matter refers to the general term for solid or liquid particulate matter dispersed in the atmosphere, and its particle size ranges from about 0.1 to 100 microns. According to particle size, it can be divided into TSP (Total Suspended Particulate) with an aerodynamic diameter of less than or equal to 100 μm and inhalable particulate matter with an aerodynamic diameter of less than or equal to 10 μm 10 (Particles with Diameters of 10μm or less). Inhalable particulate matter can be divided into fine particle PM 2.5 (ae...
