Description

Technical Field

[0001] The utility model belongs to the technical field of dust removal equipment, in particular to dust removal equipment used in workshops. Background Art

[0002] Industrial production processes, especially in industries like metalworking, woodworking, and chemical production, generate large amounts of dust. This dust not only pollutes the environment but also poses a health risk to workers. Therefore, effective dust removal methods are crucial for protecting the environment and improving production efficiency. Workshop dust removal equipment is a specialized device designed to remove and control various dust particles generated within the workshop. Through efficient filtration, adsorption, and condensation technologies, these devices effectively reduce airborne dust concentrations, improving the workshop environment, protecting employee health, and increasing production efficiency.

[0003] A search revealed announcement number CN209123589U, dated July 19, 2019, which discloses a dust removal device for preventing dust explosions in a workshop. The device comprises a dust removal cartridge, a drying box, and an activated carbon cartridge; the two support columns being symmetrically welded to the left and right end faces of the dust removal cartridge. The utility model utilizes a particle container, dust removal particles, a circular hole, a funnel-shaped water trough, a water outlet box, and a nozzle. The particle container and dust removal particles are arranged in a coordinated manner to initially filter dust-laden air, causing dust in the dust-laden air to adhere to the surface of the dust removal particles. The nozzle then sprays the water in a mist-like manner, further removing any remaining dust in the dust-laden air after passing through the particle container. Furthermore, the mist water falls into the particle container, cleaning the dust on the surface of the dust removal particles. Finally, the flushed wastewater is discharged into the funnel-shaped water trough through a plurality of circular holes formed in a rectangular array on the bottom end surface of the particle container for recirculation.

[0004] This patent has the following deficiencies:

[0005] 1. The dust removal equipment only uses a single method to wet-treat the dust-laden air through a nozzle. The dust removal effect is not ideal and it is difficult to completely remove dust from the workshop air.

[0006] 2. The dust removal equipment is not safe enough and is not suitable for dust treatment in workshops. When the dust content in the workshop is too high, it is easy to cause the risk of explosion. Utility Model Content

[0007] The purpose of the utility model is to provide a dust removal device for a workshop. By setting a first purification cylinder, a second purification cylinder and a third purification cylinder, the three measures interact with each other to achieve a better dust removal effect.
