Description
[technical field]
The present invention relates to the technical field of sewage disposal technical field of environment protection equipment, particularly sludge dewatering equipment.
[background technology]
Sewage can produce a large amount of mud after precipitation process, even if through concentrated and digestion process, water ratio is still up to 96%, and volume is very large, is difficult to disposal of dissolving, has to pass through processed, improves the solid content of mud cake, to reduce the floor space that mud is banked up.At present in industries such as machinery, environmental protection, chemical industry, often deeply dehydrating sludge process will be carried out.The water ratio of mud is high, and quantity is large, and the pollutent of enrichment high density, mud contains a large amount of organism and Determination of multiple metal elements, and perishable generation stench also multiplies mosquitos and flies; Directly can not carry out ultimate disposal, have to pass through reprocessing ability landfill or utilization, after the mud entered environment that process is disposed very well, secondary pollution will be brought directly to water body and air, also will constitute serious threat to the activity of ecotope and the mankind.Therefore, mud is very prudent in process, and in the improvement and process of sewage, the Selection and Design of sludge dewatering equipment is extremely crucial.
Big-and-middle-sized sewage work all adopts mechanical dehydration.The kind of sludge dewatering equipment is a lot, can be divided into vacuum filtering and dewatering, filter-press dehydration and centrifuge dehydration three major types by dewatering Principle.Sewage work often selects belt filter press, plate and frame(type)filter press, folded spiral shell formula water extracter and centrifugal drier.Belt filter press: price is lower, use general, current technology is comparatively ripe, easily blocks, and needs large water gaging to clean, easily causes secondary pollution; Plate and frame water extracter: cheap, moisture content of the cake is low, but easily blocks, and needs to use high-pressure pump, is not suitable for oiliness sludge dewatering; Centrifugal drier: processing power is large, but power consumption is large, and noise is large, and vibration is violent, and maintenance is difficulty comparatively; Folded spiral shell formula water extracter: not easily block, power saving, noise is not obvious with vibration, and can realize full automatic control, but be not suitable for the large sludge dewatering of the large hardness of particle, treatment capacity is less.Sheet frame water extracter is applicable to inorganic mud, and belt filter press, folded spiral shell formula water extracter, centrifugal drier are applicable to most of biochemical sludge.
Sludge dewatering treatment technology domestic at present and equipment as taped pressure filter, centrifuge are main, also has a small amount of traditional plate-and-frame filter press, can only by the dehydration of the thickened sludge of water ratio more than 93% to water ratio 75-85%, and the mud that water ratio is 75 ~ 85% is not easy to transport and cost is high, stack floor space greatly, at all cannot Direct Disposal, and adopt the secondary pollutions such as heat energy process cost of disposal high, easy generation foul smell discharge.
