Abstract
The utility model relates to a drying deice for utilization of urban sludge as resources, which is characterized in that a body comprises a sludge concentration pool, a sludge pump, a regulation agent adding machine, a mixing and stirring machine, a sludge and water separating machine, a belt filter press, a spiral conveyer, an evaporating tower, a blast blower, a heater, a speed regulation stirring machine, a spiral material adding machine, a first cyclone separator, a second cyclone separator, a dust remover, a draft fan and the like. After the sludge is primarily concentrated, dewatering regulation agents are added through the regulation agent adding machine, sanitizers are mixed in the regulation agents according to the properties of the sludge, the mixture enters the belt filter press to carry out dewatering after most water is separated through the sludge and water separating machine, the dewatered sludge is conveyed into the spiral material adding machine through the spiral conveyer, the sludge crushed through stirring is mixed with hot air sent by the blast blower, the evaporation drying is carried out in the evaporating tower, the sludge enters the two cyclone separators through the top of the evaporating tower, the dried sludge is collected in hoppers of the cyclone separators, and tail gas is treated through the dust remover. The moisture content of the sludge is greatly reduced by the drying deice.
Description
Technical field
The utility model relates to a kind of city sewage sludge reclamation and utilizes desiccation apparatus, is applied to city sewage sludge reclamation and utilizes pre-treatment, and mud is carried out granulating.
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 sanitary 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 nearly 10%, 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.
The utility model content
The utility model relates to a kind of city sewage sludge reclamation and utilizes 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, be transported to mixing tank by sludge pump, add the dehydrating and conditioning agent by 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, enter 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, in evaporator tower, carry out evaporation drying, enter 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 utility model is as follows: 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 content of mud; The utility model sludge drying device adopts automatization control, reduces manipulation strength, has avoided the remote transportation of sludge treatment; The utility model adopts totally-enclosed system, has reduced the secondary pollution of mud; Also, can arrive the requirement of recycling to the sludge drying disinfection.
