Abstract
The invention relates to a drying device for resource utilization of urban sludge, wherein the main body comprises: a sludge concentration tank, a sludge pump, a conditioner adding machine, a mixing stirring machine, a mud-water separator, a belt press filter, a screw conveyor, an evaporation tower, an air blower, a heating device, a speed-regulating mixer, a self-conveyor feed, a first cyclone separator, a second cyclone separator, a dust catcher, a draught fan and so on. The sludge is concentrated primarily, and is added with dehydrating conditioners by the conditioner adding machine, wherein disinfectants are mixed in the conditioner according to the nature of the sludge; the sludge enters the belt press filter to dehydrate after being separated out most of the water by the mud-water separator, and the dehydrated sludge is conveyed to the self-conveyor feed by the screw conveyor, and is stirred and crushed, and mixed with hot air sent by the air blower, and is evaporated and dried in the evaporation tower, and enters the two cyclone separators through the top of the evaporation tower, wherein the dried sludge is collected in hoppers of the cyclone separators, and the tail gas is treated by the dust catcher. The drying device largely lowers the water content of the sludge.
Description
Technical field
The present invention relates to a kind of city sewage sludge reclamation and utilize desiccation apparatus, be applied to city sewage sludge reclamation and utilize pre-treatment, mud is carried out prilling.
Background technology
Along with the urbanization process of China is accelerated, industrial developing rapidly, the increase of urban population, the quantity discharged of urban industry waste water and sewage is increasing, and treatment rate of domestic sewage also improves year by year, and the sludge yield of municipal sewage plant also sharply increases.A large amount of excess sludges will discharge in sewage work, and the mud of enormous amount need be done further processing, if mud can not get reasonable processing, will cause secondary pollution.According to statistics; The thousands of altogether seats of the town sewage treatment facility that puts into operation in the existing whole nation; The annual mud (dry weight) that produces is more than 1,000 ten thousand tons, and annual growth is nearly 10%, and the treatment and disposal expense of sewage sludge is higher; In whole construction costs of wastewater treatment in China factory, what be used to handle mud accounts for 20%～50%.The composition of sewage sludge is very complicated, except that containing a large amount of moisture, also contains a large amount of useful resources.Have multiplely at present for the municipal sludge treatment process, landfill, burning and comprehensive utilization are generally arranged, but before recycling, need carry out pre-treatment, nurse one's health, comprise concentrated, dehydration, drying mud.How to improve the dehydration rate of sludge treatment, and the sterilization aspect, this is the vital task of sludge treatment.Mud through after the mummification can apply to land reclamation, building materials utilization etc.
Summary of the invention
The present invention relates to a kind of city sewage sludge reclamation and utilize desiccation apparatus, it is characterized in that main body comprises: sludge thickener, sludge pump, amendment adding machine, mixing and blending machine, mud, belt filter press, worm conveyor, evaporator tower, gas blower, heating unit, speed governing stirrer, self-conveyor feed, Blowing stopper, first cyclonic separator, second cyclonic separator, fly-ash separator, induced draft fan etc.Mud is collected in sludge thickener through after tentatively concentrating, and is transported to mixing tank by sludge pump, adds the dehydrating and conditioning agent through the amendment adding machine; In amendment, be mixed with sterilizing agent according to sludge quality; Make it to reach the requirement of recycling, behind mud separating most water, get into the belt filter press dehydration; By worm conveyor dehydrated sludge is transported in the self-conveyor feed; Stirring pulverizing mud is sent hot blast here with gas blower and is mixed, and in evaporator tower, carries out evaporation drying, enters into first cyclonic separator and second cyclonic separator through the evaporator tower top; Dried mud is collected in the bucket of cyclonic separator, and tail gas is handled through fly-ash separator.
Advantage of the present invention is following: adopt hot blast evaporator tower heat transfer area big, can make moisture percentage in sewage sludge from 80%, be reduced to very soon about 15%, obviously reduced the water cut of mud; Mud of the present invention is put in makeup and is adopted robotization control, reduces manipulation strength, has avoided the remote transportation of sludge treatment; The present invention adopts totally-enclosed system, has reduced the secondary pollution of mud; Also, can arrive the requirement of recycling to the sludge drying disinfection.
