According to the dust particle pollution in the limited space of industrial enterprises, after investigation and analysis, the application requirements of industrial dust collectors in these fields are very extensive.
The national overall planning framework is very clear. For various industrial fields such as coal-fired power plants, medicine, waste incineration, steel, non-ferrous metals, cement and food processing, ultra-low emission transformations have been implemented, and corresponding implementation requirements have been issued successively across the country. Such industry transformation will be imperative.Through the on-site investigation of many enterprises, especially the coal conveying system of coal-fired power plants, the ash loading and unloading of ash storage, the escape of pharmaceutical dust, the escape of food processing dust, etc., the degree of pollution to the surrounding environment during operation It has a serious impact on the health of workers, and the flying of coal ash, dust, powder, flour, etc. also brings great waste to raw materials. Therefore, the market application of industrial dust collectors is in great demand and has a continuous room for growth.
The whole dust removal process is the result of the comprehensive effects of collision, gravity, electrostatic adsorption, screening, filtration, etc.
The general industrial dust collector structure is mainly composed of the overall shell, the host, the pipe, the socket, the dust collection components, etc. The dust collection host can be installed outdoors or in the machine room, balcony, garage, and equipment room of the building, and it can be flexibly designed according to the actual working environment.
The dust collection mechanism of the industrial dust collector is basically similar to that of the conventional bag filter, while retaining all the advantages of the bag filter.
Dust particles are sucked into the box of the dust collector by the fan through the pipe, using gravity and upward airflow, the coarse particles are preliminarily filtered by the filter part and directly dropped to the dust collection part, and the tiny particles are captured on the outer surface, and the clean gas passes through The filter parts and filter elements are filtered, decomposed and purified, and then discharged from the air outlet.
First of all, in the whole dust collector, different components play different roles to form an efficient treatment system.
When the dust enters the dust collector shell, it adheres to the filter components, and the injection system uses the pulse injection mechanism in the purification box to release compressed air instantly, causing the filter bag of the filter component to bulge rapidly, and the filter bag is removed by impact and vibration. Bag dust, the cleaned dust particles are collected in the dust removal box and dust collector area.
Secondly, the dust particles are filtered and dust-cleaned to achieve reasonable and compliant ultra-low emissions and meet environmental protection requirements.
After the dust particles are filtered, the dust is deposited on the surface of the filter bag. As the thickness of the dust particles increases, the resistance gradually increases. The dust particles fall off and settle to the dust collection parts by periodically blowing compressed air.
Dust cleaning is to remove the accumulated dust on the filter bag as uniformly as possible, but also to avoid over-treatment, to ensure stable working conditions and efficient operation.
Industrial dust collectors continue to work in the process of continuous filtration and continuous dust removal.
Generally, industrial dust collectors are designed to be small in size and high in efficiency. The air volume can meet most working conditions, and the operation and maintenance costs are low. Due to the high-efficiency dust removal capacity of the filter bag, it can complete the purification of a large number of dust particles in a small space.
Today’s industrial dust collectors have the characteristic function of multi-functional dust removal and purification, that is, they also have the functions of fresh air circulation system and filter air exchange system while dust removal.
