Oscillating balance particle monitoring equipment and method

Abstract

The invention discloses a particulate matter monitoring device and method. The device comprises a gas sampling module, a plurality of sample gas pretreatment modules, a plurality of oscillating balance sensor modules, and a control module. The gas sampling module is used for inputting collected sample gas, and carrying out the shunting of the sample gas according to difference of to-be-tested monitoring parameters. The plurality of sample gas pretreatment modules are respectively used for pretreating the sample gas of different flow paths output by the gas sampling module. Each oscillating balance sensor module comprises an independent oscillating balance sensor unit, a vibrator is arranged in each oscillating balance sensor unit, and a measuring film is arranged at the top of each vibrator and can intercept particulates. The control module is used for inputting monitoring parameters needing to be measured and automatically controlling each module to execute corresponding operation. The multi-parameter monitoring of the oscillating balance method is realized and a plurality of parameters are simultaneously measured in a single oscillating balance monitoring instrument, so that thedata difference caused by the difference between the measurement environment and equipment is reduced, the measurement accuracy is improved, and the occurrence of data inversion is avoided.

Description

technical field [0001] The invention relates to the technical field of air quality monitoring equipment, in particular to an oscillation balance particle monitoring equipment and method. Background technique [0002] In recent years, with the continuous acceleration of industrial development and urbanization, air pollution has continued to intensify, and haze has become the norm. Excessive particulate matter in the atmosphere poses a huge hazard to the health of the public. Air pollution monitoring and control is the most important and urgent thing at present. For pollution control, monitoring technology bears the brunt. Accurate and widely applicable atmospheric monitoring methods can achieve twice the result with half the effort. [0003] From the perspective of environmental monitoring policy trends, the requirements for particle monitoring accuracy are getting higher and higher, and the measurement parameters are becoming more and more comprehensive.

AI Technical Summary

Problems solved by technology

Because the installation standard requires that the distance between the sampling ports of each equipment is not very close, so the airflow and pollution concentration entering each equipment will be different

At the same time, due to differences in the measurement environment and equipment, the final data measurement accuracy is inconsistent, and there will be data upside down, which has a very bad impact
