The process of sludge drying processing of the present invention includes：1st, wet mud enters sludge drying chamber by feed system, through passing
The moisture evaporation of Sludge Surface gets into the air in defeated system and hot dry air perpendicular contact, contact process, becomes hot dry air
For clammy air.When wet mud by drying is changed into dewatered sludge, and discharge system is entered by conveyer belt；2nd, sludge drying chamber is gone out
Clammy air enter spray system, after spraying deodorization and dedusting, solid particle is removed again into filter.Spray system
Enter reclaimed water of the water from Sewage Plant, the water after deodorization and dedusting returns to Sewage Plant again, and ties net clammy air to enter table cold
Device.3rd, tie net clammy air to be exchanged heat by surface cooler and Sewage Plant reclaimed water, cold air make it that moisture content is analysed in air to the cold
Go out, the clammy air after being cooled enters the condenser of heat pump；4th, clammy air and heat pump condenser is exchanged heat
Heating, is changed into hot dry air and carries out next circulation into sludge drying chamber again；5 and the origin of heat of source pump is huge
Substantial amounts of Sewage Plant reclaimed water, i.e., absorb the heat in reclaimed water, by compressor work further absorption by evaporator
Heat is improved, the process eventually through condenser to air heat cycles.Specific sludge at low temperature drying and other treatment technique include with
Lower step：
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 (sludge exported after production mud using sludge drying machine) with preprepared moisture content 30% in back-mixing machine is filled
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, mouth is directly entered under gravity roller is squeezed
Pressure type sludge forming machine, by extrusion forming into a diameter of 3-5mm strip, while be molded drive end unit cutter bar is cut into
6-15mm length.Plain cloth is conveyed 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, to walk naturally 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 carrying part heat
Amount, by air channel, enters spray system in the presence of blast.Wet mud is changed into the dry dirt that moisture content is 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
Pouring system, after spraying deodorization and dedusting, solid particle is removed into filter again.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 plus shower nozzle as
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 for the entrainment for ensureing solid particle, filtering
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, is sent in sludge drying room and carries out next be circulated throughout again by blower fan
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 reduction noise, the refrigerant of heat pump selects R22
And 134a, compressor selects turbocompressor.In order to increase blast, circulating fan is selected without volute casing centrifugal blower fan.

Occur；The application of heat pump techniques significantly reduces the energy consumption of sludge drying in low temperature drying and other treatment unit, only commonly uses sludge and does
Change the 35%-50% of equipment energy consumption, be effectively saved cost；Thoroughly, minimum moisture content is up to less than 10% for sludge drying；This
Outside, processing system of the invention, equipment degree is high, floor space is small, and whole service process is dustless, explosion-proof, does not produce two
Secondary pollution etc..
Below by concrete application example, the invention will be further described.
With above-mentioned low-temperature sludge drying treatment system and technique, to containing that certain Sewage Plant is produced in sewage disposal process
Water rate is handled for 80% sludge, treating capacity：15 ton days, final production mud moisture content is 20%.Wherein sludge at low temperature desiccation
Owner's body is a drying box, and with heat pump, the closed connection of blower fan, monnolithic case size is 4000 × 12000 × 3500mm, interior
The portion wide 1100mm of guipure with holes, long 24000mm, low temperature desiccation temperature 50 C, sludge at low temperature desiccation machine wind speed 1.0m/s, guipure
