Description
Technical field
The utility model relates to a kind of device for dehydrating sladge waste, especially a kind of integrated pressure type barrier film sludge dehydration device that is applicable to municipal sludge and Agro-industry mud.
Background technology
Mud is the throw out that city domestic sewage and Agro-industry waste water produce in carrying out scavenging process, is the great solid waste of a kind of hazardness.If thoroughly do not handle, will cause serious secondary pollution to environment.
At present, the technological core of China's sludge treatment and difficult point are dewatering technology of mud.The degree of sludge dewatering has determined the follow-up disposal options of mud and the recontaminate degree of mud.Because China's sludge dewatering is backward in technique, cause the sludge moisture content after the dehydration higher.After the most of municipal sludge of China has gone out sewage work, just enter unordered interim stacking or simple landfill state, not only take a large amount of land resourcess, and the havoc ecotope, particularly sewage is invaded underground water, causes the part groundwater resource to be difficult to the permanent harm of restorative.
China's present stage sludge dewatering technology commonly used mainly contains four kinds: van-type pressure filtering technique, belt pressure filtering technique, centrifuge dehydration technology, filter press technology.
1, van-type pressure rate technology: it simple in structure, if but run into oiliness is arranged, the mud of viscosity just can't normally dewater, batch filtration can not move continuously, and floor space is big, the frequency of maintenance height, staff labor intensity is big, filter cloth replacement charge height, poor working environment.
2, belt pressure filtering technique: after belt filter press mixed in mixing tank through spissated mud, coacervation became the bigger cotton-shaped agglomerate of volume in the mud, isolates free water.Mud after the flocculation is transported to pressure filter sewage disposal device belt filter press, and free water is separated under the effect of gravity, forms the mud of stagnant condition, under squeeze, the shear action, progressively pushes mud, forms filter cake at last and discharges.
3, centrifuge dehydration technology: after pending mud enters whizzer, utilize the solid, liquid difference in specific gravity, and rely on centrifuge field to make it to enlarge several thousand times, mud under action of centrifugal force by sedimentation, clarified sewage is discharged by the pipeline of clear liquor, dewatered sludge is then discharged from the main frame slag-drip opening, is transferred to appointed place or directly entrucking outward transport by Shaftless screw conveyor (or body refuse transferpump) again.
4, filter press technology: pressure filter constitutes one group of filter chamber by filter plate and the filter frame alternately arranged.There is groove on the surface of filter plate, and it protrudes the position in order to support filter cloth.On the corner of filter frame and filter plate through hole is arranged, the assembling back constitutes complete passage, can feed suspension, washing water and draw filtrate.Filter plate and each jug rest of worry frame both sides are compressed the worry plate and are considered frame by hold-down gear on crossbeam.The filter cloth of considering plate and considering between the frame plays gasket seal.By charging pump suspension is pressed into filter chamber, on filter cloth, forms filter residue, until being full of filter chamber.Filtrate pass filter cloth and along the filter plate trench flow to sheet frame corner passage, concentrate to discharge.Filtration finishes, and can feed to clean to wash the water washing filter residue.After the washing, also feed pressurized air sometimes, remove remaining washings.Open pressure filter removal filter residue subsequently, clean filter cloth, pressure strip, frame begin next working cycle again.
There is following problem at present in above-mentioned technology:
1, can not continuity move adhesion easily, frequency of maintenance height.
2, moisture percentage in sewage sludge is still higher, and between 78%-83%, on average about 80%, energy consumption and medicine consumption are all bigger usually.
3, produce problems such as stench and percolate, contaminate environment once more.
4, the investment amount is big, the treatment operating costs height, and do not reach the expection treatment effect, business burden is heavy.
