Dust concentration uniformity detection device and control system

Abstract

The invention discloses a dust concentration uniformity detection device and a dust concentration uniformity control system. The detection device comprises a dynamic dust supply device; a dust collection air duct used for accommodating dust sent by the dynamic dust supply device; a plurality of dust concentration sensors dispersedly mounted in the detection section of the dust collection air duct; and a main control module which is used for acquiring the dust concentration collected by the dust concentration sensor in real time. The control system comprises a dust generating position generating module which generates and outputs next dust generating position data of a dust generating opening of the dynamic dust supplying device; a dust generation module which is used for generating and outputting next dust generation data of the dynamic dust supply device; and a dust generation control module which is used for controlling the position and the dust generation amount of a dust generation opening of the dynamic dust supply device according to the dust generation position data and the dust generation amount data. According to the invention, a dust environment with uniform concentration can be flexibly and efficiently provided according to different scenes, and verification of a dust concentration measuring instrument is facilitated.

Description

technical field [0001] The invention relates to the field of environmental detection, in particular to a dust concentration uniformity detection device and a control system. Background technique [0002] Dust can cause damage to electromechanical equipment and affect its normal working life. Once the explosion-prone dust meets the explosion conditions, dust explosion can occur under the action of appropriate energy and ignition source. Therefore, the measurement of dust concentration has become the focus of mine safety production. heavy. At the same time, the problem of dust pollution in the air environment in our country is increasing day by day. PM10 and PM2.5 have gradually risen to become the main air pollutants in the ambient air in many cities in our country, causing major harm to human health, environment, climate and atmospheric visibility. The control of particulate matter emissions has also become a priority concern for international environmental protection. Dus...

Problems solved by technology

[0003] At present, the verification of domestic dust meters adopts JJG846-2015 "Verification Regulations for Dust Concentration Measuring Instruments". The value traceability technology is the sampling flow traceability. This technology can only reflect the dust sampling flow performance, and cannot directly calibrate the main measurement performance of the instrument - the parameter of dust concentration.

At the same time, the old-fashioned dust-generating blower is bulky and inefficient, and the stability and uniformity of dust generation cannot meet the requirements of the verification.
