Dust removing method

Abstract

The invention discloses a dust removing method. The dust removing method is characterized by comprising the following steps that an area with dust needing to be collected is covered with a dust collecting cover; multiple compressed air streams are sprayed to the area covered by the dust collecting cover from the outside of the dust collecting cover, so that dust particles in the dust collecting cover are in the suspension state; a negative pressure pipeline communicated with the inner portion of the dust collecting cover is arranged in the dust collecting cover, and the dust in the suspension state is sucked into a collecting device from the inner portion of the dust collecting cover through negative air streams in the negative pressure pipeline. By the adoption of the dust removing method, a brush and water spraying are not needed, a road can be efficiently cleaned, primary raised dust and secondary raised dust are avoided, the problem that dust pollution is severe is completely solved, water resources are saved by adopting the compressed air instead of water spraying, and cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of environmental dust cleaning, in particular to a dust removal method. Background technique [0002] Mechanical tools have been widely used in existing ground cleaning. Mechanical cleaning generally adopts brushes to roll and sweep, and the garbage on the ground is gathered together with a disc brush, and then the garbage is sucked into the garbage collection box with a fan. When cleaning, in order to prevent dust, it will continuously spray water on the ground and brushes to reduce dust activity and reduce dust. There are following problems in this dust removal method: [0003] 1. When water spray is used to reduce dust, the muddy water formed by water and soil will adhere to the brush and seriously affect the cleaning effect, and at the same time increase the cleaning and maintenance costs of brushes and other components; [0004] 2. The use of water spray to reduce dust not only wastes water resources,...

AI Technical Summary

Problems solved by technology

[0004] 2. The use of water spray to reduce dust not only wastes water resources, but also pollutes the environment and affects the appearance and travel of other vehicles; and in winter, water spray can easily lead to icy roads and traffic accidents;

[0005] 3. The muddy water formed during cleaning increases the burden on the urban drainage system and easily blocks the sewer pipes

Whether it is the existing brush or the continuous blowing of dust to the suction port, this will cause or cannot avoid primary and secondary dust
