Air quality detection equipment and method

Abstract

The invention provides air quality detection equipment and method. The air quality detection equipment comprises a dust particle concentration measuring module, a pollution gas concentration measuringmodule and an air driving module, wherein the dust particle concentration measuring module is used for measuring and sampling dust with different grain diameters respectively; the pollution gas concentration measuring module is serially connected with the dust particle concentration measuring module, and is used for carrying out synchronous sampling on the concentration of pollution gas; the airdriving module is used for driving air to flow through the dust particle concentration measuring module and the pollution gas concentration measuring module. Synchronous and accurate sampling and accurate measurement for dust particles and pollution gas are realized by setting the dust particle concentration measuring module and the pollution gas concentration measuring module; the sampling speedand measurement response speed of pollution gas are improved by setting the air driving module; the dust particle concentration measuring module and the pollution gas concentration measuring module are serially connected in the flowing direction of air, to fulfill the purpose of synchronous sampling, so that the integration of equipment is improved, and the equipment size and processing difficultyare reduced.

Description

technical field [0001] The present disclosure relates to the technical field of air quality monitoring, in particular to an air quality detection device and method. Background technique [0002] In recent years, with the continuous acceleration of industrial development and urbanization, air pollution has continued to intensify, smog has become the norm, and various toxic gases and organic volatiles in the atmosphere often exceed the standard. Whether it is dust particles or various polluting gases, there is a huge hazard to the health of the public. Therefore, it is imminent to monitor air pollution. [0003] Accurate and detailed atmospheric monitoring can guide the direction of control and governance, achieving twice the result with half the effort. Currently, the most feasible solution for refined atmospheric monitoring is grid monitoring. That is, multiple air quality monitoring devices are set at intervals in one monitoring point to measure the concentration of dust...

Problems solved by technology

[0004] However, in the process of realizing the present disclosure, the applicant found that in the existing technical solution, the air sampling of the two parts of dust particle measurement and pollution gas measurement is independent of each other, and the pollution gas sampling adopts diffusion type, which has slow response and sampling and measurements are very inaccurate

In addition, the post-calibration of monitoring equipment is very inconvenient
