Description

Technical Field

[0001] This utility model relates to the field of dust treatment equipment, and in particular to a dust collection and recovery device for conditioning tanks. Background Technology

[0002] As a pretreatment unit, the conditioning tank often requires the addition of lime for neutralization. The lime powder is added to the conditioning tank via a conveyor. Due to gravity, a large amount of lime dust is generated during this process, which pollutes the working environment and endangers the health of operators. Traditional dust removal devices for conditioning tanks mostly use fixed spray systems for dust suppression.

[0003] However, the working status (start / stop, speed, and load) of the feeding equipment (screw conveyor) directly affects the diffusion path and concentration distribution of lime dust. The fixed-angle spray device is difficult to adjust in real time according to the dust diffusion direction. When the feeding impact airflow changes suddenly or the wind direction changes, spray blind spots are likely to occur, causing some dust to leave the dust settling area.

[0004] Therefore, how to make the spray angle of the dust removal device in the conditioning tank adjustable has become a technical problem that urgently needs to be solved. Utility Model Content

[0005] The purpose of this invention is to provide a dust removal and recycling device for a conditioning tank to solve the problems mentioned in the background art.
