Description
Technical field
The utility model relates to grain slag cooling water water circulation system sedimentation basin.
Background technology
At present, in smelting industry, grain slag melts liquid discharges from blast furnace grain slag mouth, and grain slag melts liquid and is cooled directly with water at grain slag mouth place and pours granulating pit with water by granulated slag groove, water in granulating pit flows into pond by water channel, and the water in sewage pump extraction pond transfers to grain slag mouth and continues on for grain slag cooling.This kind of water circulation has several shortcoming: one, in pond, the clay content of water gets more and more, the cooling effect of water declines, two, the conveyance conduit of cooling water recirculation system can block gradually because of the beginning that increases of clay content in water, discharge is caused to reduce, water circulation effect declines, three, when there is above two kinds of situations, supplementary new clear water is just needed to increase cooling effect, water consumption is caused to increase, too increase the water yield in water circulation system, if the water capacity making the water yield exceed water circulation system will cause sewage overflows, (otherwise processed bothers well) four, the mud precipitated in pond to need to wait after blast furnace blowing out just easy cleaning, but it is large to process one action amount for a long time, labour intensity is large, and the mud cleaning difficulty of pipe interior blocking is large.Five, the lead silicate containing certain ingredients in mud, during cleaning pond, need release the sewage in pond, the lead silicate of discharging along with sewage causes the wasting of resources, also increases the workload of the last treatment tank in smeltery.Six, after tank drain, the mud of recovery is wet, and concentrated accumulation has water loss, bad process.
Summary of the invention
In order to overcome the various problems that existing smelting enterprise uses the blast furnace grain slag circulatory system to occur, the utility model provides grain slag cooling water water circulation system sedimentation basin, use this grain slag cooling water water circulation system sedimentation basin, the amount of sludge precipitated in pond can be reduced when blast furnace works, clay content in effective reduction sewage, alleviate pipeline stopping state, and air-dry recovery can be carried out to mud simultaneously, the water flowed out in mud still flows in pond and recycles, add resource recycling rate, reduce the disposable treating capacity of the last sewage disposal system in smeltery, reduce labor intensity.
In order to achieve the above object, the utility model solves the technical scheme that its technical problem adopts is following design:
Sedimentation basin divides three grades by the degree of depth, and first stage precipitation tank is the darkest, and three grades of sedimentation basins are the most shallow.Dark 3.6 meters of first stage precipitation tank pond, dark 3.3 meters of second-level settling pond pond, dark 3 meters of three grades of sedimentation basin ponds.Water channel one end is connected with granulating pit, the other end is connected with first stage precipitation tank, there is one-level connected entrance water channel and first stage precipitation tank junction, there is secondary connected entrance the junction of first stage precipitation tank and second-level settling pond, three grades of connected entrances of the connectivity part of second-level settling pond and three grades of sedimentation basins, one-level connected entrance is on the upper left side of first stage precipitation tank, secondary connected entrance is in the lower right of first stage precipitation tank, three grades of connected entrances are in the lower left of second-level settling pond, there is filter screen at connected entrance place, one-level connected entrance filter screen order number is maximum, and three grades of connected entrance filter screen order numbers are minimum.There is the air-dry pond of individual mud on first stage precipitation tank side, and the air-dry pond of mud has a tank to lead to first stage precipitation tank, and there is filter screen the air-dry pond of mud and tank junction, bottom the air-dry pond of mud and bottom of gullet, becomes 1 ~ 3 degree of angle, tilt to sedimentation basin direction with ground.
The beneficial effects of the utility model are: can reduce the amount of sludge precipitated in pond when blast furnace works, clay content in effective reduction sewage, alleviate pipeline stopping state, and air-dry recovery can be carried out to mud simultaneously, the water flowed out in mud still flows in pond and recycles, add resource recycling rate, reduce the disposable treating capacity of the last sewage disposal system in smeltery, reduce labor intensity.
