Problems solved by technology

[0003] In order to overcome various problems in existing smelting enterprises using the blast furnace water slag circulation system, the present invention provides a sedimentation tank for the water slag cooling water circulation system. Using the water slag cooling water circulation system sedimentation tank can reduce the precipitation in the water pool when the blast furnace is working. The amount of silt can effectively reduce the silt content in the sewage, relieve the blockage of the pipeline, and at the same time, the silt can be air-dried and recycled. The water flowing out of the silt still flows into the pool for recycling, which increases the resource recycling rate and reduces the final waste of the smelter. The one-time treatment capacity of the sewage treatment system reduces the labor intensity

Embodiment Construction

[0014] The sedimentation tank is divided into three levels according to the depth, the first-level sedimentation tank 1 is the deepest, and the third-level sedimentation tank 3 is the shallowest. The first-level sedimentation tank is 3.6 meters deep, the second-level sedimentation tank is 3.3 meters deep, and the third-level sedimentation tank is 3 meters deep. One end of the water channel 4 is connected to the slag tank, and the other end is connected to the primary sedimentation tank 1. There is a primary communication port 5 at the connection between the water channel 4 and the primary sedimentation tank 1, and there is a connection between the primary sedimentation tank 1 and the secondary sedimentation tank 2. The secondary communication port 6, the tertiary communication port 7 at the connection between the secondary sedimentation tank 2 and the tertiary sedimentation tank 3, the primary communication port 5 is at the upper left of the primary sedimentation tank 1, and th...

Abstract

The invention discloses a sedimentation tank of a water granulated slag cooling water circulation system. The sedimentation tank is divided into three stages according to the depth, wherein the first-stage sedimentation tank is the deepest, and the third-stage sedimentation tank is the shallowest; a granulating basin is connected with one end of a water ditch, and the first-stage sedimentation tank is connected with the other end of the water ditch; a first-stage communicating port is formed in the connecting part between the water ditch and the first-stage sedimentation tank; a second-stage communicating port is formed in the connecting part between the first-stage sedimentation tank and a second-stage sedimentation tank; a third-stage communicating port is formed in the connecting part between the second-stage sedimentation tank and the third-stage sedimentation tank; a sludge air drying tank is arranged beside the first-stage sedimentation tank; a water channel formed in the sludge air drying tank is led to the first-stage sedimentation tank.

Description

technical field [0001] The invention relates to a sedimentation tank of a slag cooling water circulation system. Background technique [0002] At present, in the smelting industry, the slag melt is discharged from the slag outlet of the blast furnace. The slag melt is cooled by water at the slag outlet and washed into the slag pool with the water through the slag tank. The water in the slag pool passes through the water channel It flows into the pool, and the water pumped by the sewage pump is transferred to the water slag outlet to continue cooling the water slag. This kind of water cycle has several disadvantages: 1. The mud content of the water in the pool is increasing, and the cooling effect of the water is reduced. The flow rate decreases and the water circulation effect decreases. 3. When the above two situations occur, it is necessary to add new clean water to increase the cooling effect, resulting in an increase in water consumption, and also increases the water vo...
