The heat of receipts improves, eventually through process of the condenser to air heat cycles.Specific sludge at low temperature drying and other treatment technique bag
Include following steps：
1) wet mud of the moisture content more than 80% first is sent in oar blade type sludge back-mixing machine by screw conveyor,
Dewatered sludge with preprepared moisture content 30% in back-mixing machine fills (using the sludge of sludge drying machine outlet after production mud)
Divide mixing, be allowed to become the wet mud that moisture content is 80%.
2) wet mud of moisture content 80% comes out from the bottom of back-mixing machine, is directly entered a mouthful two pairs of rollers under gravity and squeezes
Pressure type sludge forming machine, the strip by extrusion forming into a diameter of 3-5mm, while the cutter for being molded drive end unit cuts into bar
6-15mm length.Plain cloth conveys in the first layer micropore belt chain of the entrance of sludge drying chamber in the presence of natural gravity
On guipure.
3) wet mud moves towards the other end for one section from first layer micropore belt chain transmission net band, is going to other end terminal
When, fall naturally on following second layer guipure, reversely transmission, walks naturally to fall in the storage bin of discharge system when being at the end
(also can multilayer).In transmit process, wet mud and the hot dry air perpendicular contact that temperature is that 50 DEG C of relative humidity are 20%, connect
The moisture evaporation of Sludge Surface gets into the air during touching, and hot dry air is changed into clammy air, while carries a part of heat
Amount, by air channel, enters spray system in the presence of blast.Wet mud is changed into dry dirt of the moisture content less than 30% by drying
Mud, and discharge system is entered by transmission net band, then be transported to by a conveying worm part in back-mixing machine, a part is directly defeated
It is sent on outward transport vehicle.
4) the clammy air of sludge drying chamber is gone out, temperature is at 35 DEG C or so, and relative humidity is more than 95%.It is directly entered spray
Leaching system, after spray deodorization and dedusting, solid particle is removed again into filter.The water source of wherein spray system is to fall
The reclaimed water of sewage plant, temperature is between 15-25 DEG C.For more preferable deodorization and dedusting, spray system elects perforated pipe as and adds shower nozzle
Water-locator and corrugated filler.I.e. humid air and the water sprayed are cross-flow contact on filler, and the water after deodorization is directly gone
Dirt is dispatched from the factory processing, and humid air removes solid particle again into filter.Wherein in order to ensure the entrainment of solid particle, filter
The filter core of device is using collapsible.
5) 30 DEG C of clammy air enters finned surface cooler after dedusting deodorization and the reclaimed water of 15-25 DEG C of sewage plant is entered
Row heat exchange, clammy air make it that moisture content is separated out in air, and sewage treatment plant is guided to through water pipe to the cold.20 DEG C after being cooled full
Enter the finned cooler of heat pump with clammy air.
6) the clammy air of 20 DEG C of saturation and the condenser of water source heat pump units are fully exchanged heat, and clammy air is become again
The hot dry air for being 20% for 50 DEG C of relative humidity, it is sent to again in sludge drying room by blower fan and carries out next be circulated throughout
Journey.And the origin of heat of source pump is the sewage plant reclaimed water of enormous amount, i.e., by the shell and tube evaporator of heat pump set system
The heat in reclaimed water is absorbed, further the heat of absorption is improved by compressor work, eventually through finned cooler
Process to air heat cycles.Wherein in order to improve temperature and efficiency and reduce noise, the refrigerant of heat pump selects R22
And 134a, compressor select turbocompressor.In order to increase blast, circulating fan is selected without volute casing centrifugal blower fan.
