A dust concentration uniformity detection device and control system

Abstract

The invention discloses a dust concentration uniformity detection device and a control system. The detection device comprises: a dynamic dust feeding device; a dust collecting air duct to accommodate the dust emitted by the dynamic dust feeding device; In the detection section of the dust collection air duct; the main control module obtains the dust concentration collected in real time by the dust concentration sensor; the control system includes: a dust generating position generation module, which generates and outputs the next dust generating position of the dust generating port of the dynamic dust feeding device data; the dust generation module, which generates and outputs the next dust generation data of the dynamic dust feeder; the control dust module, according to the dust generation position data and the dust generation data, controls the dynamic dust feeder’s dust outlet. location and dust generation. The invention can flexibly and efficiently provide a dust environment with uniform concentration according to different scenarios, which is convenient for the verification of the dust concentration measuring instrument.

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 damage electromechanical equipment and affect its normal working life. Once the explosion-prone dust is met, dust explosion can occur under the action of appropriate energy and ignition source, so dust concentration measurement has become the top priority of mine safety production. heavy. At the same time, the problem of dust pollution in my country's air environment 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 my 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. Dust measuring instruments are widely used in dust e...

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.
