Problems solved by technology

However, due to the high precision requirements for the lifting of the sampling tube, the translation of the filter paper, and the paper feeding of the filter paper, the structure of the whole device is very complicated. The space is large, and it is inconvenient to use and maintain; moreover, it is almost impossible to add more detection channels, and it is impossible to obtain more parameters at the same time

Abstract

The invention discloses a beta-ray-method three-channel atmospheric particulate monitor which comprises a man-machine interface, a dust pumping mechanism, a sampling device used for collecting air flow, a filter paper rack used for installing filter paper, a pressing device used for pressing the filter paper, and a detecting device used for detecting beta-ray loss. The filter paper on the filter paper rack penetrates through the pressing device and the detecting device horizontally. The sampling device is located above the filter paper on the filter paper rack and provided with three-way channels. The dust pumping mechanism is located below the filter paper on the filter paper rack and provided with three-way channels corresponding to the channels of the sampling device one to one. The structure of the whole monitor is simplified, and the sampling device provided with the three-way channels and the dust pumping mechanism provided with the three-way channels are arranged, so that the beta-ray-method three-channel atmospheric particulate monitor is provided; three parameters can be sampled and monitored at the same time, and use is convenient.

Description

technical field [0001] The invention belongs to the technical field of atmospheric detection equipment, and in particular relates to a three-channel atmospheric particle monitor using the beta ray method. Background technique [0002] Atmospheric particulate matter is a general term for solid or liquid particulate matter dispersed in the atmosphere. Atmospheric particles have different particle sizes, are inhaled and deposited in different parts of the respiratory system, and have different harms to the body. Those larger than 5 μm mostly stay in the upper airway, and those smaller than 5 μm mostly stay in the bronchioles and alveoli. As people pay more and more attention to the health hazards of atmospheric particulate matter, the monitoring technology of atmospheric particulate matter is also improving. [0003] The existing monitoring methods of atmospheric particulate matter mainly include: β-ray absorption method, micro-oscillating balance method and light scattering ...
