Regenerator 3-1 is again passed by through piping again, and carries out an internal heat exchange, realizes the first time heat temperature raising of air, institute
It states heating air to enter in condenser 3-3 by pipeline, condenser 3-3 is by meeting under internal cooling medium liquefaction exothermic effects to hot-air
It is heated again, realizes second of heat temperature raising of air；The air of the reheating enters belt type dry by pipeline
In dry device 2；
The hydrofuge module includes that the hot side air outlet of regenerator 3-1 and wet-emitting blower 3-13, the regenerator 3-1 are logical
Piping is by hydrofuge solenoid valve 3-6 (hydrofuge solenoid valve 3-6 is opened, and dehumidify magnetic valve 3-5 is closed) and wet-emitting blower 3-13 phase
Even, by hot-air, from gas outlet 3-12 discharge, (during hydrofuge, fresh air inlet 3-10 passes through the wet-emitting blower 3-13
Solenoid valve 3-6 is opened, and is sucked fresh air, is reached hydrofuge effect).
The condenser 3-3 is placed in a link behind regenerator 3-1, not only realizes to inside condenser 3-3
The cooling of cooling material, change so traditional cold mode (traditional cold mode by outside blower to condenser dry, from
And reach the cooling to condenser 3-3, cool down here by using the air come out through regenerator 3-1 to condenser 3-3),
The primary heating to dry air is also achieved, energy consumption is reduced, realizes the Multi-class propagation of energy；Regenerator 3-1 and evaporator 3-2
Bottom of the frame installs water container, for collecting condensed water, guarantees drying in rack, prevents from getting rusty；The regenerator condensed water
Disk 3-8 and evaporator condensation water pond 3-7 enters in water condenser 3-4 by condensate pipe 3-18, and the water condenser is placed in
Around compressor 3-15, is cooled down by way of water cooling to the compressor in work, prolonged the service life.
Present apparatus working principle is as follows: there are two types of the present apparatus working method dehumidification mode and hydrofuge mode, under dehumidification mode
Dehumidify magnetic valve opening hydrofuge solenoid valve and air inlet solenoid valve are closed, and solenoid valve opening sludge, which enters, when device is started to work cuts mud
Device and full of mud device is cut, closes solenoid valve and feed inlet is sealed, the sludge quantity in mud device to be cut is reduced to a certain amount of
When, reopen charging solenoid valve.The hydraulic drive valve of discharge port is opened once every a period of time, and intermittence will be after desiccation
Sludge excludes drying device body, so that most of the time discharge port is also in the state of sealing.Sludge enters drying device body
After fall on first layer mesh bag, decelerating motor drive mesh bag rotation, when strip sludge pass through CCD camera when, camera intermittence clap
Sludge photo is taken to be sent to controller analysis processing, having ring lamp around camera is camera light filling, when sludge is fallen from first layer mesh bag
When entering second layer mesh bag, the moisture percentage in sewage sludge on-line measuring device installed between upper layer and lower layer mesh bag is started to work, and passes through machine
Tool handgrip grabs the sludge fallen from first layer mesh bag, is put into test box body and completes to measurement of water-content coefficient, is inhaled by residue
It takes device that the mud sample after drying is taken out test cabinet and blows on second layer mesh bag, sludge passes through second layer net
It is dropped into after bag is dry and then excludes drying device body in mud extraction hopper, also there is several CCD cameras interval on second layer mesh bag
Continuous acquisition sludge image.When transmission mesh bag operates without stopping, heat pump system synchronous operation, negative-pressure air fan will be in drying device body
Air extraction send to dehumidifying heat pump, this process both made the air in whole system flow, and by with hot wind
Negative pressure in drying device body is realized in intake valve cooperation, and the intracorporal pressure-detecting device real-time detection air pressure of drying device feeds back to control
Device processed, and then change the working condition of negative-pressure air fan and hot wind intake valve, hot wind passes through second layer mesh bag from drying device bottom
Using first layer mesh bag, the moisture in sludge is entered in dry hot-air, so that dry air becomes the air of saturation,
The hot-air of saturation enters cyclone separator by dehumidifying pipeline, the preliminary dust particles removed in air, then using removing
Dirt cloth bag further removes dust.Saturation hot-air first passes through heat exchanger and tentatively cools down after entering dehumidifying heat pump, passes through temperature
Thermal energy in hot-air is passed to the cold air come out from evaporator by difference, realizes nature heat exchange.The hot-air tentatively to cool down
Into evaporator, the expanded valve gasification of freon in evaporator is absorbed heat, and the temperature reduction of hot-air is condensed out in air and is taken
The moisture of band.Hot sky after cooling down twice is condensed out a large amount of condensed water and send condenser to compressor to compression into piping
Machine cooling, hot-air is cooled to and arrives the heat that heat exchanger absorption hot-air tentatively cools down after cold air again, to realize cold sky
The preliminary heating of gas, and then cold air enters condenser, and the freon in condenser, will be warm through compressor compresses liquidation exothermic reaction
Air heating setpoint temperature carries out heat drying to sludge, runs so on circulate subsequently into drying device body.
