Description

A kind of sledge dress oily sludge dewatering unit
Technical field
The utility model relates to a kind of sludge treatment equipment, and particularly a kind of oil field sludge is handled and adorned sludge dehydration device with sledge, especially a kind of sledge dress oily sludge dewatering unit.
Background technology
In the produced water disposal process of field joint stations, can produce a large amount of oily sludges.The oily sludge intractability is big, and the processing cost height does not still have at present economical and effective, simple and practical treatment facility, causes that mud is not effectively addressed in the present field joint stations, constantly accumulates and influences the operation of produced water disposal system.Therefore, oily sludge presses for the simple and practical sludge treatment device of a kind of economy in the joint station.Mud dewatering method commonly used at present is a mechanical dehydration, comprises filter press, belt press filtration and centrifuge dehydration etc.It is general through concentrating to carry out the preceding mud of mechanical dehydration, concentrates and generally adopts the concrete sludge sump, and thickened sludge dewaters at pump to dewatering unit.Such cover sludge treatment Facilities Construction cycle is long, floor space is big, pipeline is long, construction operational management inconvenience.
Summary of the invention
But the purpose of this utility model provides a kind of sledge dress oily sludge dewatering unit that can reduce floor space, the good convenient construction of treatment effect and make things convenient for operational management.
The purpose of this utility model is achieved in that a kind of sledge dress oily sludge dewatering unit, which comprises at least settling bowl, agitator, whizzer, wet-pit, clear liquid case; Settling bowl is pond at the bottom of the square awl, agitator is fixed on settling bowl Chi Ding, the paddle of agitator puts in the settling bowl, it is characterized in that: settling bowl is located on the clear liquid case, settling bowl and clear liquid case are formed a square bar pond, mud water distribution pipeline and detergent line are arranged in the settling bowl, and settling bowl communicates with the clear liquid case by mud supernatant liquor collection tube; The settling bowl sludge out pipe links to each other with the whizzer import, and the whizzer water outlet links to each other with clear liquid case water-in; There is mud mouth the whizzer lower end, and the posticum of clear liquid case links to each other with wet-pit; Dosing pump is positioned on the medicine storing pot, and dosing pump drug pipeline links to each other with cleaning pipeline, whizzer mud inlet.
The advantage that the utility model provides is: the utility model comprises concentration basin, clear liquid water tank, whizzer, chemicals dosing plant, clear liquid efflux pump and housing etc., the function that concentrates and dewater of mud that it is integrated, and all parts are concentrated on the sled piece.Have mud and concentrate and dehydrating function, the oily sludge of water ratio about 99% can be handled water ratio≤80%, the mud after the processing becomes solid-state, and convenient transportation centrally disposes.This equipment integral adopts one skid installing type structure, and function is integrated, takes up an area of for a short time, and convenient operation and management preferably resolves the unmanageable problem of mud of oil field produced water treatment generation.
During work, mud (water ratio about 99%) at first enters sludge thickener and adds flocculation agent simultaneously and carries out natural gravity and concentrate, mud (water ratio 95%~98%) after sedimentation concentrates enters centrifuge, simultaneously also add flocculation agent and carry out centrifuge dehydration, the moisture percentage in sewage sludge after the dehydration≤80%.Mud concentrated supernatant and centrifuge dewatering parting liquid are collected by liquid-collecting box.
Description of drawings
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing:
Fig. 1 is an example structure principle schematic of the present utility model.
Among the figure: 1, settling bowl; 2, clean pipeline; 3, dosing pump; 4, medicine storing pot; 5, whizzer; 6, mud car; 7, wet-pit; 8, clear liquid case; 9, mud supernatant liquor collection tube; 10, mud water distribution pipeline; 11, detergent line; 12, agitator; 13, water outlet; 14, mud mouth; 15, sludge out pipe.
Embodiment
As shown in Figure 1, a kind of sledge dress oily sludge dewatering unit which comprises at least settling bowl 1, agitator 12, whizzer 5, wet-pit 7, clear liquid case 8; Settling bowl 1 is pond at the bottom of the square awl, agitator 12 is fixed on settling bowl 1 Chi Ding, the paddle of agitator 12 puts in the settling bowl 1, it is characterized in that: settling bowl 1 is located on the clear liquid case 8, settling bowl 1 and clear liquid case 8 are formed a square bar pond, mud water distribution pipeline 10 and detergent line 11 are arranged in the settling bowl 1, and settling bowl 1 communicates with clear liquid case 8 by mud supernatant liquor collection tube 9; Settling bowl 1 sludge out pipe 15 links to each other with whizzer 5 imports, and whizzer 5 water outlets 13 link to each other with clear liquid case 8 water-ins; There is mud mouth 14 whizzer 5 lower ends, and whizzer 5 mud mouth mud are by mud car 6 entruckings outward transport; The posticum of clear liquid case 8 links to each other with wet-pit 7; Dosing pump 3 is positioned on the medicine storing pot 4, and dosing pump 3 drug pipelines link to each other with cleaning pipeline 2, whizzer 5 mud inlets.
When this device specifically moved, flushing was shut down in experience (1) sedimentation, (2) centrifuge dehydration, (3), (4) efflux four processes:
Sedimentation
The equipment intermittent operation, the mud that enters about 10m3 by mud water distribution pipeline 10 reaches the full liquid level of settling bowl at every turn, and dosing pump 3 adds flocculation agent to cleaning pipeline 2 simultaneously, agitator 12 begins to stir, mud staticly settles then, carries out the natural gravity sedimentation, makes the further concentrating and precipitating of mud.
(2) centrifuge dehydration
Whizzer (frequency conversion soft start) is opened, after reaching specified speed, slowly open settling bowl 1 sludge out pipe feed valve, fluidised form mud (water ratio about 95%~98%) through gravity settling enters whizzer 5, under action of centrifugal force, solids is released rotary drum by the extruding of the screw mechanism in the whizzer from an end of whizzer 5, and clear liquid flows out to clear liquid case 8 from the other end.Dewatered sludge adopts special-purpose mud band encapsulation back outward transport to centrally dispose.
(3) shut down flushing
When the slag notch solid reduces, illustrate that the mud base conditioning finishes in the slurry tank, close feed valve, slow machine halt.Supernatant liquor in the back usefulness of the shutdown clear liquid case 8 is through wet-pit 7 supercharging washing centrifugers 5.The residual mud of settling bowl 1 pool wall wall also utilizes supernatant liquor to be pressurized to detergent line 11 routine cleaning through wet-pit 7.
(4) efflux
The equipment final product is solid-state mud cake and supernatant liquor.Mud cake is transported outward with mud car 6, and supernatant liquor effluxes through wet-pit 7 automatically according to the liquid level of clear liquid case 8.
