The sludge spraying and drying device has convenient installment, simple operation and high drying efficiency, and causes no environmental pollution.
Description
Technical field
The utility model relates to a kind of sludge drying device.
Background technology
Along with China's rapid development of economy and urbanization process and brewage, the developing rapidly of industries such as papermaking, chemical industry, the construction of sewage treatment plant increases, the output of mud increases sharply, the processing of mud has become focus point new in the comprehensive environmental improvement with disposing.Because sludge moisture content height (generally at 75-85%), particle is thin, impurity is many, bad hydraulic permeability, to such an extent as to formed large stretch of marsh in the Treatment of Sludge field, not only occupies the farmland, and causes new pollution.At present, the minority place adds mud fillers such as some bentonites, wood chip and makes fertilizer and be used for the flowers and plants forest.It is with the mud landfill disposal that part of contaminated water is handled, and most of enterprise will carry out simple air storage after the sludge dewatering.As time goes on, the mud volume of cargo in storage is increasing, will take a large amount of soils.And can cause serious secondary pollution to surrounding environment, a large amount of mud have become the heavy burden of Treatment of Sludge factory, and new pollution can be caused in the landfill zone, moreover can be fewer and feweri for the soil of landfill.
A large amount of mud that sewage treatment plant is produced have carried out harmless treatment, and the mud after handling is used for aspects such as production composite fertilizer, realize making the optimum systemic circulation of material, environment, ecology, are the problems that the present stage people demand urgently researching and solving.
Summary of the invention
The utility model provides a kind of mud has been carried out desiccation apparatus, not only mud has been carried out harmless treatment by this device, and be used for farm-forestry crop as fertilizer or organic-inorganic compound mixed fertilizer, bio-fertilizer, the fertile inserts of BB, realize the zero-emission of mud factory effluent, the sludge drying processing is accomplished energy-conservation, efficient, innoxious.
The utility model is achieved through the following technical solutions:
This device comprises grinder 1, feed bin I2, conveying worm 3, screw pump 4, spray gun 5, spray granulation drier 6, cooler 7, drum screen extension set 8 and the feed bin II9 that connects successively, air compressor machine 10 connects spray gun 5 by air accumulator 11, spray granulation drier 6 connects drum screen extension set 8, heating flue 12 and exhaust gas processing device respectively, and cooler 7 connects exhaust gas processing device.
Exhaust gas processing device comprises dirt pocket 13, cyclone dust collectors 14, blower fan 15 and the chimney 16 that connects successively, and dirt pocket 13 connects spray granulation drier 6 and cooler 7 respectively.
The utility model is the mud of slip form, enter spray granulation drier by whitewashing and carry out granulation and drying, and carry out purified treatment with exhaust gas processing device, can not cause environmental pollution, and this device is easy for installation, technological operation is simple, and mummification efficient height can keep the organic principle in the raw sewage not to be destroyed.
Description of drawings
Accompanying drawing is a structured flowchart of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail:
As shown in the figure, grinder 1, feed bin I2, conveying worm 3, screw pump 4, spray gun 5, spray granulation drier 6, cooler 7, drum screen extension set 8 and feed bin II9 are connected successively, air compressor machine 10 connects spray gun 5 by air accumulator 11, spray granulation drier 6 connects drum screen extension set 8, heating flue 12 and dirt pocket 13 respectively, and cooler 7, dirt pocket 13, cyclone dust collectors 14, blower fan 15 and chimney 16 are connected successively.
Send into raw material feed bin I2 after earlier the mud about water content 75%-85% being pulverized grit things such as impurity in the mud such as stone, husky rock, fragment of brick by grinder 1, in the conveying worm 3 feeding screw pumps 4 by feed bin I2 below, during producing, air compressor machine 10 press air to store then by air accumulator 11.The middle binder slurry of being got by screw pump 4 mixes with the middle pressure air from air accumulator 11, after spray gun 5 atomizings, form whitewashing, whitewashing constantly is sprayed in the spray granulation drier 6 on the material curtain of being kicked up by the rotating cylinder flight that is mainly formed by interior outside returns by the whitewashing pipeline, particle constantly forms and grows up, the hot flue gas that forms in hot-blast stove simultaneously enters spray granulation drier 6 by heating flue under the effect of spray granulation drier 6 afterbody blower fans 14, with during hot flue gas fully contacts, moisture is removed in the continuous mummification of particle.Granule materials after the mummification is discharged through the discharging end socket of spray granulation drier 6 afterbodys, deliver in the cooler 7 by auxiliary equipment and to cool off, cooled granule materials enters in the drum screen extension set 8 by auxiliary equipment and sieves, sieve qualified granule materials and enter feed bin II9 as finished product, pack after metering, underproof fine particle returns spray granulation drier 6 and carries out the granulation mummification as masterbatch again.
The waste gas that spray granulation drier 6 and cooler 7 produces in the granulating and drying process enters and enters cyclone dust collectors 14 behind the dirt pocket 13 and carry out purifying and dedusting, and the waste gas after the processing is discharged by chimney 16 by blower fan 15.
The dewatered sludge finished product can be used to produce compound fertilizer, and it mixes in batch mixer with powder NPK after pulverizing by pulverizer, machines through technological processes such as granulation, oven dry, coolings.
