Description
Technical field
The present invention relates to a kind of sewage concentrating clarifying equipment, specifically a kind of black water thickener that carries out concentrating clarifying to coal preparation plant's black water.
Background technology
The coal preparation plant of China is wet coal preparation factory more than 95%, and in wet coal preparation factory, water is the most important work medium, and ton raw coal water consumption reaches 2～4m
3Polluted by the fine-grained solids in the raw coal in the dressing of coal by washing process as the water of working media, become black water, for the water consumption that reduces coal preparation plant with realize coal preparation plant's cleaner production, wastewater zero discharge; Need be multiplexing after the black water purified treatment, concentrate then gets into follow-up Separation of Solid and Liquid operation.
The concentrator that coal preparation plant uses at present mainly is raker thickener and pipe chute thickener.Wherein: raker thickener relies on weight free settling under the gravity effect of solid particle self, because the solid particle granularmetric composition in the black water is thin, sinking speed is little, and treating capacity is merely 2.5～3.5m
3/ m
2H causes equipment volume big, and floor space is big, and the maximum specification diameter meets or exceeds 100m, and equipment price is high, and cell body is the reinforced concrete structure, long construction period, especially cold district, and winter can not normal construction, and the completion time of project of whole coal preparation plant is increased.Pipe chute thickener is the basis with the shallow layer settling theory, adopts thin-walled porous inclination square hole pipe, and equivalent area is big, the coal slime settling height is short, and disposal ability can reach 3.6～5.0m
3/ m
2H, but structure is not perfect, thin-walled porous inclination square hole pipe and cell body bottom easy blocking; The cell body volume is big, adopts the reinforced concrete structure, and difficulty of construction is big, and is long in time limit.
Summary of the invention
The present invention be directed to the many deficiencies that exist in the prior art, provide that a kind of utilization flocculation and floc sedimentation layer filtration theory concentrate, volume is little and disposal ability meets or exceeds 10m
3/ m
2The black water thickener of h.
Realize that the technical scheme that the foregoing invention purpose adopts is: a kind of black water thickener, comprise sedimentation main body, the feeding device that is filled with black water and be positioned at the clarified solution feeder in the sedimentation main body top perimeter outside, wherein:
A, said sedimentation main body are the cylinder-cone of steel construction, and the cone angle of cone is 45-65 °;
B, said feeding device are loaded on the central upper portion position of sedimentation main body, comprise main body, feed pipe and discharge nozzle; Feed pipe is arranged on the body wall middle part; The top of discharge nozzle places in the main body, and the top of discharge nozzle is connected with the leading screw bottom of running through main body, and leading screw places the outer top of main body to be set with handwheel; The lower end of discharge nozzle places 2-3m place under the center liquid level of black water of sedimentation main body.
The black water that carries out concentrating clarifying with this thickener is the black water that has flocculant.
The main body of feeding device is arranged on the top center of sedimentation main body.
Compared with prior art, this black water thickener disclosed by the invention adopts steel construction sedimentation main body, has the following advantages with respect to traditional concrete structure sediment main body: structural parameters are easy to guarantee; The inner wall smooth degree is good, can increase the cone cone angle, reduces the thickener overall height; Construction speed is fast, shortens the construction period; North cold area, construction is not influenced by cold snap; Equipment manufacturing cost is low.The cell body volume of this thickener is little, and floor space is little, is not easy to stop up, and concentrated effect is good, and thickening efficiency is high.
Description of drawings
Fig. 1 is an overall structure sketch map of the present invention.
Fig. 2 is a feeding device of the present invention.
Fig. 3 is a fundamental diagram of the present invention.
Among the figure: thickener sedimentation main body 1, clarified solution feeder 2, operating platform 3, feeding device 4, discharge nozzle 5, main body 6, handwheel 7, leading screw 8, flexible seal device 9, feed pipe 10.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is further specified.
Referring to accompanying drawing 1-2; The disclosed this black water thickener of the present invention; Comprise thickener sedimentation main body 1, the feeding device 4 that is filled with black water and be positioned at the clarified solution feeder 2 in the sedimentation main body top perimeter outside; Wherein: thickener sedimentation main body 1 is up big and down small steel construction cylinder-cone, and the cone angle of cone is 45-65 °.The top of thickener sedimentation main body 1 is provided with the operating platform 3 that is connected with sedimentation main center.
The lower end of discharge nozzle 5 places 2-3m place under the center liquid level of black water of sedimentation main body 1.The main body of feeding device is arranged on the top center of sedimentation main body.Discharge nozzle 5 is provided with flexible seal device 9 with the junction of main body 6.
The black water that adopts this thickener to carry out concentrating clarifying is the black water that has flocculant.The course of work of this black water thickener is: the feed pipe 10 of the feeding device 4 of the black water that adds flocculant through being positioned at sedimentation main body central upper portion gets into main bodys, feeds 2-3m degree of depth place under the sedimentation main center liquid level by discharge nozzle 5 then, and the fine-grained solids particle is the formation floc sedimentation under " bridges formation " effect of flocculant; Big floc sedimentation quality is big, and the subsidence velocity under the gravity effect moves downward greater than the current rate of climb; Little floc sedimentation quality is little, and subsidence velocity is less than the current rate of climb, so move upward with ascending current under the gravity effect; Because sedimentation main body 1 is up big and down small cone structure, with the increase of height, the 1 sectional area phase strain of sedimentation main body is big; The current rate of climb diminishes; On certain altitude, the subsidence velocity of floc sedimentation equals the rate of climb, promptly suspends at this place.Most of quality is in a small range in the formed floc sedimentation; Therefore, on the certain altitude of thickener, can form a certain thickness fine and close floc sedimentation layer, along with carrying out continuously of above process; Solid particle sinks down into the underflow that forms high concentration behind sedimentation main body 1 bottom and is discharged from; Coming out from peripheral overflow in sedimentation main body 1 top that is raised to waterborne, collects through clarified solution feeder 2 and discharge recycle, realizes concentrating and Separation of Solid and Liquid of black water.
The floc sedimentation layer has two effects: the one, and the floc sedimentation that quality is littler is retained down, and stops its come-up, play a role in filtering, the 2nd, between the inner floc sedimentation of floc sedimentation layer, annex each other and form big floc sedimentation, quicken the floc sedimentation sedimentation.
