Description
Technical field
This utility model relates to a kind of novel sludge drying processing device, belongs to technical field of environment protection equipment.
Background technology
At present, mechanical sludge dewatering is with porous material for filter medium, pressure differential on two sides, filter medium both sides is as motive force, moisture in mud is forced through filter medium, discharge with the form of filtrate, solid particle is trapped within filter medium, becomes the filter cake after dehydration (mud cake), thus realizing sludge dewatering.The method of conventional machinery sludge dewatering has following three kinds: (1) adopts the ventilation evaporation that moisture air in mud or steam are got rid of by pressurization or evacuation, and relatively common is vacuum filtration process；(2) relying on the squeeze and filter method of mechanical compress effect, generally high concentration sludge is adopted filter press technique, common method is the filter press method of the belt filter press technique of continuous dehydration and intermittently dehydration；(3) utilizing centrifugal force to remove the centrifuge dehydration method of moisture in mud as power, conventional is rotating cylinder centrifuging.
Most domestic sewage treatment plant dehydrated sludge moisture content is about 80%, and namely sludge dewatering is not thorough, and sludge volume is big, it is impossible to direct utilization, and this brings extreme difficulties to the final disposal of mud.
Drying sludge is the processing method that mud is carried out deep dehydration by using artificial thermal source with industrial equipment, although the direct result of drying sludge is the decline of moisture percentage in sewage sludge, but compared with mechanical dehydration, its application purpose and effect are all very different.
Summary of the invention
In order to overcome problems of the prior art, this utility model provides a kind of novel sludge drying processing device, this device should use artificial heat, and mud, more than 100 DEG C, is processed by temperature, not only realize deep dehydration, and there is annealing effect, and the product that drying sludge processes, its moisture content can be controlled in less than 20%, the level of the microbial activities in suppression mud, changes the physics of mud, chemistry and biological nature simultaneously.
nullThe technical solution adopted in the utility model is: the drying process device of a kind of novel mud，It includes charger，Charger sends mud into sludge dry system，It is characterized in that: described sludge dry system includes aerator、Air heater、Disperser、Pneumatic conveyer dryer、Cyclone dryer、Cyclone separator、Cleaner unit and air-introduced machine，Described aerator is sent into air and is heated by steam-heated air heater，Obtain hot-air more than 100 DEG C to enter disperser and be 80% with the moisture content entered from charger、By disperser、The dewatered sludge pulverized is mixed to form hot-air sludge stream，Mud in described air sludge stream enters cyclone dryer after drying by the pneumatic conveyer dryer of thtee-stage shiplock and continues dry，Air sludge stream after drying enters cyclone separator centrifugation and goes out the moisture content dewatered sludge less than 5%，Dewatered sludge is discharged from the bottom of cyclone separator，Hot-air and dewatered sludge dust enter cleaner unit from the top of cyclone separator，The isolated dewatered sludge dust of removing dust device is discharged from the bottom of cleaner unit，Hot-air in cleaner unit is extracted out from the top of cleaner unit by air-introduced machine.
The beneficial effects of the utility model are: the drying process device of this novel mud includes charger, aerator, air heater, disperser, pneumatic conveyer dryer, cyclone dryer, cyclone separator, cleaner unit and air-introduced machine, air heater is heated to air more than 100 DEG C of entrance dispersers and is 80% with the moisture content entered from charger, the dewatered sludge pulverized by disperser is mixed to form hot-air sludge stream, mud in air sludge stream is dried by pneumatic conveyer dryer and the cyclone dryer of thtee-stage shiplock, air sludge stream after drying enters cyclone separator centrifugation and goes out the moisture content dewatered sludge less than 5%, hot-air and dewatered sludge dust enter cleaner unit, the isolated dewatered sludge dust of removing dust device is discharged from the bottom of cleaner unit.This device uses artificial heat that mud is processed, and not only achieves deep dehydration, and has annealing effect, it is suppressed that the level of the microbial activities in mud, changes the physics of mud, chemistry and biological nature simultaneously.Dry mud can be used for fertilizer, construction material etc..

Detailed description of the invention
Fig. 1 illustrates the schematic diagram of the drying process device of a kind of novel mud.The drying process device of this novel mud includes charger 3,3 mud of charger are sent in sludge dry system, and sludge dry system includes aerator 1, air heater 2, disperser 9, pneumatic conveyer dryer 4, cyclone dryer 5, cyclone separator 6, cleaner unit 7 and air-introduced machine 8.1 air of aerator is sent into and is heated by steam-heated air heater 2, obtain hot-air more than 100 DEG C to enter disperser 9 and be 80% with the moisture content entered from charger 3, the dewatered sludge pulverized by disperser 9 is mixed to form hot-air sludge stream, mud in air sludge stream enters cyclone dryer 5 after drying by the pneumatic conveyer dryer 4 of thtee-stage shiplock and continues dry, air sludge stream after drying enters cyclone separator 6 centrifugation and goes out the moisture content dewatered sludge less than 5%, dewatered sludge is discharged from the bottom of cyclone separator 6, hot-air and dewatered sludge dust enter cleaner unit 7 from the top of cyclone separator 6, the isolated dewatered sludge dust of removing dust device 7 is discharged from the bottom of cleaner unit 7, hot-air in cleaner unit 7 is extracted out from the top of cleaner unit 7 by air-introduced machine 8.
Adopting above-mentioned technical scheme, aerator blows air in dryer system, is heated into hot-air through air heater.The dewatered sludge of moisture 80%, pneumatic conveyer dryer is entered through charger, mass-and heat-transfer exchange is carried out with hot-air, hot-air quick washing material is also sufficiently mixed the contact area maximization making fluidization of material and air thus evaporating rapidly moisture content in moment with material, gas-particle two-phase enters after cyclone dryer is further dried and enters cyclone separator gas solid separation, gas obtains dried mud after separating then through cleaner unit, moisture percentage in sewage sludge is less than 5%, the thorough sterilizing of mud simultaneously, dry mud can be used for fertilizer, construction material etc..
This device is provided with blower system and induced draught system, and aerator can double as disperser.Cyclone separator dry tenacity is big, and automaticity is high.Pneumatic drier dry tenacity is big, and pneumatic conveying drying is high due to air velocity, and particle is good dispersion in the gas phase, it is possible to using long-pending for particle all surfaces as dry effective area, therefore, dry effective area is greatly increased.Simultaneously as dry time dispersion and agitaion, make gasification surface constantly update, therefore, the heat transfer, the mass transport process intensity that dry are bigger.The pneumatic drier thermal efficiency is high, and pneumatic conveying drying adopts gas-solid phase cocurrent cooling operation, simultaneously, it is possible to the unit process joint operation such as dry, pulverizing, screening, conveying, not only process simplification, and operates and is prone to automatically control.Applied range pneumatic conveying drying can be used in various powder and granule shape material.
