Fine particulate matter underway monitor

Abstract

The invention provides a fine particulate matter underway monitor. Thefine particulate matter underway monitor comprises a bottom plate, the upper end of the bottom plate is fixedly connected with a clamping plate, the outer side of the clamping plate is fixedly connected with a clamping block, and the outer side of a conveying pipe is fixedly connected with an electromagnetic control valve. According to the fine particulate matter underway monitor, a structure capable of being rapidly mounted and dismounted is arranged between the fine particulate matter underway monitor and a cruise vehicle, a gas suction device is additionally arranged in the fine particulate matter underway monitor equipment body, and then gas is guided into the monitoring device through a PDSM film through the gas suction device; an electron is removed through the mass analyzer and vacuum ultraviolet lamp soft ionization, molecular ions with respective characteristics are generated, all the molecular ions fly in the vacuum flight time mass analyzer with the same path, the molecular ions with the small mass-to-charge ratio reach an end point firstly, and the molecular ions with the large mass-to-charge ratio reach the end point later. Therefore, different substances can be qualitatively or quantitatively determined according to the sequence of the flight time reaching the end point, so that the PM2.5 fine particulate matters in the air can be monitored.

Description

technical field [0001] The invention relates to the technical field of PM2.5 monitoring, in particular to a navigation monitor for fine particles. Background technique [0002] Fine particulate matter is also called fine particles, fine particles, PM2.5. Fine particulate matter refers to particulate matter in the ambient air with an aerodynamic equivalent diameter less than or equal to 2.5 microns. It can be suspended in the air for a long time, and the higher its concentration in the air, the more serious the air pollution. Although PM2.5 is only a small component of the earth's atmospheric composition, it has an important impact on air quality and visibility. Compared with coarser atmospheric particles, PM2.5 has a small particle size, large area, strong activity, and is easy to attach toxic and harmful substances (such as heavy metals, microorganisms, etc.), and has a long residence time in the atmosphere and a long transportation distance. Therefore, it has a greater ...

Problems solved by technology

[0005] The invention provides a navigation monitor for fine particles, which is used to solve the problem that most of the existing navigation monitors used for fine particles are directly installed with the monitoring cruise vehicle. When installing, the installation of most navigation monitors The structure is inconvenient to disassemble and install, which makes it not very convenient to install and disassemble the navigation monitor. At the same time, when the existing fine particles are monitored, there is no good monitoring device for effective and accurate monitoring of fine particles in the atmosphere. Make the data inaccurate and greatly reduce the technical problems of practicality
