Dust suppression device for tundish operation

Abstract

The invention relates to the field of dust treatment, in particular to a dust suppression device for tundish operation. The dust suppression device comprises a dust suppression chamber body, a movablesealing cover, a driving structure, a supporting structure, a sealing structure, a dust falling structure, a spraying structure and a dust stopping curtain; the height of the movable sealing cover can be adjusted through the driving structure, the position of the movable sealing cover with the height adjusted can be fixed through the supporting structure, the supporting effect on the movable sealing cover is achieved, and the bottom side of the dust suppression chamber body can be sealed through the sealing structure; meanwhile, dust accumulation is avoided, high-pressure water flow mixed with liquid medicines can be provided through the spraying structure, a settling effect on dust in the dust suppression chamber body can be achieved, the mixed liquid medicines provided by the spraying structure can be sprayed through the dust falling structure, meanwhile, the spraying angle can be adjusted according to needs, and the settling effect on the dust is improved.

Description

technical field [0001] The invention relates to the field of dust treatment, in particular to a device for suppressing dust during tundish operation. Background technique [0002] Tundish metallurgy is a special out-of-furnace refining technology, which is a key link in the production process from steel smelting and refining to solid continuous casting slabs to ensure excellent steel quality. With the advancement of high-efficiency continuous casting, tundish metallurgy technology has become an essential and important technology for high-efficiency continuous casting. Tundish metallurgy can prevent secondary oxidation and gas absorption of molten steel, improve the flow state of molten steel, prevent slag entrainment and promote the floating of inclusions, fine-tune the composition of molten steel, control the shape of inclusions and precisely control the superheat of molten steel. In the process of tundish metallurgy, a large amount of dust will be generated in the operati...

Problems solved by technology

In the process of tundish metallurgy, a large amount of dust will be generated in the operation room, which will cause serious harm to the health of the staff. In order to control the dust hazard, the process commonly used in the industrial dust removal industry is the bag type dust removal technology. This bag Type dust collectors are generally not suitable for high-temperature working environments, and workers need to enter the box to check and replace filter bags during work, which will cause great harm to the health of employees

[0003] However, the bag-type dust removal technology commonly used in the industry currently filters and separates dust particles by installing dust filter bags, but this technology has certain limitations, and it cannot meet the requirements for a large amount of explosive dust in the tundish
