Abstract

The invention discloses an air particulate sampler. The air particulate sampler comprises a cylindrical sampling volumetric flask, an air inlet pipe arranged at the top end of the sampling volumetric flask, an air exhaust pipe arranged at the bottom end of the sampling volumetric flask and a particulate mass concentration sensor and a particle number concentration sensor both arranged on the inner side wall of the sampling volumetric flask, wherein double layers of electronic adsorption screen plates are arranged at the middle section of the sampling volumetric flask, the interval between the upper-layer electronic adsorption screen plate and the lower-layer electronic adsorption screen plate is 15mm, adsorption holes are distributed on the upper-layer electronic adsorption screen plate and the lower-layer electronic adsorption screen plate in a crisscrossed manner, the electronic adsorption screen plates are connected with a single chip microcomputer, the single chip microcomputer is connected with a display device, a draught fan is arranged on the air inlet pipe, and a micro air pump is arranged on the air exhaust pipe. The air particulate sampler disclosed by the invention greatly improves the detection accuracy, realizes flow detection and automatic adjustment, has perfect functions, and not only can carry out sampling, but also can intuitively display sampling results to improve the work efficiency.

Description

technical field [0001] The invention relates to the technical field of air monitoring, in particular to an air particle sampler. Background technique [0002] With the continuous progress of global industrialization, environmental pollution is becoming more and more serious, and various air dusts are harmful to human health. In recent years, the "Ambient Air Quality Standards" related to PM2. quality. Numerous studies have confirmed that particulate matter can cause damage to the respiratory and cardiovascular systems, leading to asthma, lung cancer, cardiovascular disease, birth defects and premature death. A clean atmosphere is one of the necessary conditions for human beings to survive. However, with the rapid development of my country's industrialization and national economy, a large amount of harmful substances are discharged into the air, which deteriorates the air quality and seriously affects the daily life of residents. Therefore, air quality needs to be monitore...
