Description
Technical field
The present invention relates to grain slag cooling water water circulation system sedimentation basins.
Background technique
Currently, grain slag melts liquid and is discharged from blast furnace grain slag mouth, and grain slag melts liquid and is cooled directly with water at grain slag mouth in smelting industry
And granulating pit is poured by granulated slag groove with water, the water in granulating pit flows into pond by water channel, and the water that sewage pump extracts pond passes
It transports to grain slag mouth and continues on for grain slag cooling.This kind of water circulation has several drawbacks in that: one, the clay content of water is more and more in pond,
The cooling effect of water declines, two, the conveyance conduit of cooling water recirculation system can because in water clay content increase beginning and block gradually,
Cause water flow to reduce, the decline of water circulating effect, three, when there is both the above situation, it is necessary to supplement new clear water increase it is cold
But effect causes water consumption to increase, and also increases the water in water circulation system, if water is made to be more than the water capacity of water circulation system
It is just square after the blast furnaces blowing outs such as amount will result in sewage overflows, and the mud precipitated in (otherwise processed bothers well) four, pond needs
Just clear up, but big, the large labor intensity that could handle one action amount for a long time, and inside pipeline blocking mud cleaning difficulty
Greatly.Five, the sewage in pond need to be released when clearing up pond containing the lead silicate of certain ingredients in mud, with sewage discharge
Lead silicate causes the wasting of resources, also increases the workload of the last treatment tank in smeltery.Six, it after tank drain, returns
The mud of receipts be it is wet, concentrate accumulation has water loss, bad processing.
Summary of the invention
There is various, present invention offer to overcome the problems, such as existing smelting enterprise using the blast furnace grain slag circulatory system
Grain slag cooling water water circulation system sedimentation basin can be when blast furnace works using the grain slag cooling water water circulation system sedimentation basin
The amount of sludge precipitated in pond is reduced, the clay content in sewage is effectively reduced, alleviates pipeline stopping state, and simultaneously can be to mud
It carries out air-drying recycling, the water flowed out in mud, which still enters into pond, to be recycled, and is increased resource recycling rate, is reduced
The disposable treating capacity of the last sewage disposal system in smeltery, reduces labor intensity.
In order to achieve the above object, the technical solution adopted by the present invention to solve the technical problems designs as follows:
Sedimentation basin divides three-level by depth, and first stage precipitation tank is most deep, and three-level sedimentation basin is most shallow.First stage precipitation tank pond is 3.6 meters deep, second level
Sedimentation basin pond is 3.3 meters deep, and three-level sedimentation basin pond is 3 meters deep.Water channel one end is connect with granulating pit, the other end and first stage precipitation tank phase
Even, there are a level-one communication port in water channel and first stage precipitation tank junction, and there are two cascades in the junction of first stage precipitation tank and second-level settling pond
The three-level communication port of the connectivity part of port, second-level settling pond and three-level sedimentation basin, level-one communication port is in the upper left of first stage precipitation tank
Side, second level communication port have filter at the lower left of second-level settling pond, communication port in the lower right of first stage precipitation tank, three-level communication port
Net, level-one communication port strainer mesh number is maximum, and three-level communication port strainer mesh number is minimum.There is a mud to air-dry beside first stage precipitation tank
Pond, mud, which air-dries pond, has a sink to lead to first stage precipitation tank, and mud, which air-dries pond and sink junction, strainer, and mud air-dries pond
Bottom and bottom of gullet are tilted with ground at 1 ~ 3 degree of angle to sedimentation basin direction.
The beneficial effects of the present invention are: the amount of sludge precipitated in pond can be reduced when blast furnace works, dirt is effectively reduced
Clay content in water alleviates pipeline stopping state, and can carry out air-drying recycling simultaneously to mud, and the water flowed out in mud still flows
Enter in pond and recycle, increase resource recycling rate, reduces the disposable of the last sewage disposal system in smeltery
Treating capacity reduces labor intensity.
Detailed description of the invention
