AI Technical Summary

Problems solved by technology

However, the traditional filter membrane sampler usually only produces one sample 24 hours a day, and the time resolution of the sample is low, so it is impossible to capture the pollution source or the time trend of the atmospheric oxidation process, and it is impossible to accurately control the haze

Abstract

The invention discloses a high-time-resolution atmospheric particulate sampler, which comprises an air inlet pipe, filter membrane modules and a pump evacuation pipe sequentially connected in a sealedmode. The multiple filter membrane modules are evenly arranged in the circumferential direction of the rotary disc, a stepping motor driving the rotary disc to rotate is arranged at the axis of the rotary disc, the stepping motor drives the rotary disc to rotate at regular intervals, and the two ends of the next filter membrane module are connected to the air inlet pipe and the pump evacuation pipe in a sealed mode correspondingly. Full-automatic continuous collection of air samples is realized, the time change trend of a pollution source or an atmospheric oxidation process can be captured, and accurate haze treatment or scientific research demand meeting is facilitated.

Description

technical field [0001] The present application relates to an atmospheric particulate matter sampler, in particular to an atmospheric particulate matter sampler with high time resolution. Background technique [0002] The mass concentration and chemical composition of atmospheric particulate matter are very important factors affecting human health, climate change, and visibility. A series of scientific studies have demonstrated that the analysis of the mass concentration and chemical composition of particulate matter provides important insights into atmospheric aerosol chemistry, cloud condensation nuclei processes, and public health impacts. The mass concentration of particulate matter and the characterization of particulate matter components can be achieved by using a sampler to collect atmospheric particulate filter membrane samples and selecting appropriate chemical analysis techniques (IC, ICP-MS, EC / OC, GC-MS, XRF, etc.). Atmospheric particle samplers can be divided in...
