Description
Technical field
The present invention relates to sludge treatment device technical field, particularly the sealed low temperature sludge drying treatment system of one.
Background technology
Along with industrial development and growth in the living standard, create increasing sanitary sewage and trade effluent, the mud that these are useless, sewage can produce a large amount of water ratio about 99% after purification of water quality process, becomes the mud that water ratio is about 80 ~ 85% after the device for dehydrating sladge waste dehydration of routine.Along with the increase of sewage load, mud annual production is very fast increase also.According to finding display, the mud that waste water processing station and sewage work produce has nearly 80% not obtain appropriate minimizing and recycling treatment.Mud that is how that output is huge, complicated component carries out minimizing and resource utilization, has become problem anxious to be resolved.The further mummification of mud is a kind of method of very feasible sludge reduction, and this kind of mud after predrainage is dry further by the drying plant of routine, to reach the object of decrement and convenient transport.And the current problem that sludge drying device ubiquity energy consumption is higher, energy utilization rate is lower, further for the mud after this kind of predrainage mummification is not produced again secondary exhaust emission, and how efficiently reduction energy consumption is a technical barrier in field of Environment Protection.
At present for further mummification water ratio 80 ~ 85% the method for mud, the more sludge drying process equipment of domestic and international application is mainly heat drying technology, comprises the processing units such as fluidized-bed mummification, belt-type drying, the mummification of Horizontal revolving disc type, oar blade type mummification, the mummification of vertical disc formula, spraying mummification.Drying process and equipment are while considering technology maturation and investment running cost, need select in conjunction with the requirement of different specific resistance to filtration project, meanwhile, the problems such as the dust produced in mud drying process, foul smell discharge need to increase treatment facility in addition and prevent and treat.
Sludge drying device energy consumption conventional is in the market higher, and generally need use under the condition having waste heat source to heat.If directly use the conventional energy (as Sweet natural gas, coal, steam etc.), processing costs is high, is difficult to remain normal and runs.And sewage work is many without waste heat thermal source, lack the heat that can directly recycle, according to conventional heat drying technology, will drop into a large amount of funds for the construction of thermal source and energy consumption, cost performance is too low.In addition, existing sludge drying technique implements drying and other treatment mainly with single performance equipment, inevitably there is the problem of dust, foul smell discharge, if do not increased process facility for prevention and control in addition, will certainly cause secondary pollution to environment while dewatered sludge.
Summary of the invention
Technical problem to be solved by this invention is to provide the sealed low temperature sludge drying treatment system of a kind of energy-saving and environmental protection, safety.
For solving the problems of the technologies described above adopted technical scheme: a kind of sealed low temperature sludge drying treatment system, the sealing and circulating air channel comprising sludge drying chamber and be connected with sludge drying chamber, recirculation blower is provided with to order about gas at sealing and circulating air channel internal circulation flow in described sealing and circulating air channel, described sealing and circulating air channel is also connected with thermal-pump unit, described thermal-pump unit is by compressor, condenser, current regulator and vaporizer composition are to form refrigerant circulation circuit, described condenser and vaporizer are located in sealing and circulating air channel to carry out evaporation heating and dehumidification by condensation to gas respectively.
Further, described drying sludge indoor are provided with multilayer from the bottom to top in order to carry the conveying belt of mud, each layer described conveying belt staggered arrangement and the throughput direction of adjacent two layers conveying belt is contrary.
Further, the bottom of described sludge drying chamber is provided with the inlet mouth be connected with sealing and circulating air channel, the top of described sludge drying chamber is provided with the air outlet be connected with sealing and circulating air channel, the mud import of described sludge drying chamber is arranged on top and accepts conveying by most top layer conveying belt, and the sludge outlet of described sludge drying chamber is arranged on bottom and is accepted by lowest layer conveying belt and sends.
Beneficial effect: this sealed low temperature sludge drying treatment system is by closed removal moisture drying mode and rely on heat pump to carry out vapor condensation recovery of heat, drying is carried out without the need to additionally adding the external heat sources such as steam, do not need to consume any fuel, also without waste gas waste heat discharge, working cost reduces greatly, its more energy-saving and environmental protection, safety; And the temperature of drying medium, humidity facilitate regulating and controlling, not by ectocine, easy to use.
