Automatic dust separation and purification control method and system

Abstract

The invention discloses an automatic dust separation and purification control method and system, and belongs to the field of particulate matter separation and purification. The system comprises a central control logic unit, a fan control unit, an adsorption liquid cleanliness detection unit, a dust collection weight detection unit, an air suction port wind speed detection unit, a dust collector cleaning and replacing alarm unit and a dust collector cleaning and replacing alarm unit. The central control logic unit is used for controlling the fan control unit to control a fan to start accordingto the set fan working rotating speed; the air suction port wind speed detection unit is used for detecting air suction port wind speed; the dust collection weight detection unit is used for detectingthe dust collection weight; the adsorption liquid cleanliness detection unit is used for detecting the cleanliness of an adsorption liquid; the central control logic unit is further used for judgingwhether one or more of a dust suction device, a dust collection device and the adsorption liquid need to be cleaned and replaced or not according to the wind speed of a wind suction opening, the dustcollection weight and the cleanliness of the adsorption liquid. Automatic separation and purification control and rapid adjustment of rolling mill dust can be achieved.

Description

technical field [0001] The invention belongs to the field of separation and purification of particulate matter, and is applied to industries such as metallurgy, petroleum processing, chemical industry, building materials and food processing, etc., where the emission of particulate matter from industrial sources accounts for a large proportion, and is specifically an automatic dust separation and purification control method for rolling mills. Background technique [0002] During the hot rolling process of steel, the secondary oxide scale on the surface of the rolled material will be separated from the surface of the rolled material as the roll is squeezed, resulting in a large amount of oxide scale dust. Especially when rolling silicon steel, a large amount of oxidation dust will be generated. Rolling mill dust pollutes the entire factory environment and is the main source of dust pollution in steel rolling mills. [0003] At present, the commonly used dust removal method is...

AI Technical Summary

Problems solved by technology

[0004] At the same time, the particles of rolling mill dust are very small (micron level), will rise and disperse with hot air, and easily deposit deep in the lungs of the human body, which is extremely harmful to health

And the fine oxide particle dust will shorten the life of the electronic equipment on site, deposit on the rolling mill rack and driving track, and fall on the strip later, affecting the surface quality of the product

The water mist pressure dust method improves the dust wrapping of the rolling mill to a certain extent, but it is difficult to fundamentally solve the dust accumulation phenomenon on the rolling mill
