Existing dust removal technologies mostly use mechanical, chemical or physical methods, such as spraying and vacuuming. Although these methods are effective to a certain extent, they often have disadvantages such as high energy consumption, high cost and great impact on the environment. In recent years, functional microbial technology has gradually been applied to environmental governance, using the adsorption and degradation capabilities of functional microorganisms or plants on pollutants, becoming an emerging environmental protection technology. By optimizing the growth environment of functional microorganisms or plants, their dust capture and degradation effects can be improved. With the rapid development of the Internet of Things, sensor technology and artificial intelligence, intelligent monitoring and automatic control systems have been widely used in various fields. Combining these technologies with dust removal systems can achieve real-time monitoring, data analysis and intelligent adjustment, and improve dust removal effects and efficiency.

The efficient intelligent storage and recovery system realizes the efficient recycling of resources, which is in line with the concept of sustainable development; the functional microbial dust removal system sprays more environmentally friendly and safe functional microbial dust suppressants, and through three-time impact atomization and cutting, the contact area between the functional microbial dust suppressant and the dust is increased, thereby improving the dust suppression rate.

A spiral scraper and a rotating nozzle are installed at the top of the functional microbial dust reduction system. The two work alternately with a working time ratio of 1:9. The spiral scraper can be extended and retracted up and down and rotated to scrape the gel on the inner wall of the dust collector shell.
