A dust generation system and its treatment method

Abstract

The invention provides a dust generating system and a treatment method thereof, the system includes an air flow generating device, a dust generating device, a concentration sensor, a control system, a feedback system and an aperture regulator, and the dust generating device includes a dust container and a dust The dust generating bin, the dust container is located above the dust generating bin, the bottom of the dust container is provided with a dust flow hole, and the aperture regulator is connected to the dust flow hole. The dust generation system of the present invention reduces the equipment space and prevents the dust in the dust container from being blown away through the connection and matching of devices, especially the design of the dust generation bin and the dust container; the system can adjust the output The dust concentration keeps the dust concentration uniform and stable, and the dust that does not meet the set concentration is recycled, which not only prevents it from entering the experimental system, but also can be reused, avoiding the waste of materials.

Description

technical field [0001] The invention belongs to the technical field of air pollution research, and relates to a dust generating system and a treatment method thereof. Background technique [0002] At present, the generation of fine particles mainly comes from industrial production, such as coal-fired power plants and the steel industry. For the treatment of fine particle pollution, my country mainly uses high-efficiency dust removal devices for control, including electrostatic precipitators, bag filters, wet dust collectors and Cyclone dust collector, etc. In order to improve the working performance and collection efficiency of the dust collector, a large number of dust removal experiments are required, and the basic condition of the dust removal experiment is to be able to form uniform and stable dust. [0003] The current experimental research mostly uses a dust generator and an air compressor to complete the dust generation, but the dust generation of the dust generator i...

AI Technical Summary

Problems solved by technology

[0003] The current experimental research mostly uses a dust generator and an air compressor to complete the dust generation, but the dust generation of the dust generator is unstable, and the dust concentration is poorly adjustable, and manual adjustment is required during the concentration adjustment process. The operation is inconvenient and lacks accuracy. At the same time, during the adjustment process, the dust that does not meet the required concentration of the experiment will also enter the experimental device, causing systematic errors in the experiment.

CN 206262506 U discloses a kind of solid fine particle aerosol generating and sending system, this system adopts axial flow fan to aerosol forced circulation, has guaranteed the uniformity of aerosol particle density; Aerosol storage tank is bigger to make the decline of aerosol particle concentration Smaller, but the system is more inconvenient to control, and has poor selectivity to dust of different particle sizes

CN202070332 U discloses an aerosol generating device capable of adjusting the amount of dust, including an ash storage tank, an ash delivery device and a residual dust hopper. The amount cannot be adjusted automatically, and the dust cannot be selectively sent
