The specific embodiment of description is only used to explain the utility model, is not used to limit the utility model.
Shown in Figure 1, a kind of hot air circulation garbage dewatering device includes the drying room 3 of sealing, is set in the drying room
There is garbage conveyor structure 7, after the top side of the drying room is equipped with pending garbage inlet 5, bottom side is equipped with drying
The lower section of rubbish discharge port 6, the garbage conveyor structure is equipped with air-distribution device 8, and rubbish is promoted for being conveyed in garbage conveyor structure
Hot wind is introduced to dry the rubbish being deposited on the garbage conveyor structure into drying room during rubbish.
Exhaust outlet is provided at the top of the drying room, the exhaust outlet connects the air inlet of dehumidifier 4 by gas exhaust piping,
The gas outlet of the dehumidifier is by piping connection using cement kiln head waste gas residual heat as the gas-to-gas heat exchanger 1 of heat source
Cold air air inlet, the cycle air supply pipeline and institute that the heat exchange air outlet of the gas-to-gas heat exchanger is constituted through circulating fan 2
State the air inlet connection of air-distribution device.
Tiny structure is used in the upper shell of drying room 3, is avoided drying indoor refuse odor and be leaked, rubbish is conveyed in rubbish
The hot-air drying under the reciprocal promotion of mechanism, moved from feed inlet to discharge port direction, while be sent into from air-distribution device.
Hot-air containing water vapour enters the wherein moisture of dehumidifier 4 and is condensed discharge, and cold air enters gas-gas through return airway and exchanges heat
Device 1 blasts drying room 3 by after the heat smoke heating from cement kiln head through circulating fan 2.Form the multiple closed cycle of air
It avoids arranging outside foul smell, influences environment.
The pending garbage inlet can be arranged as required to lock gas with rubbish discharge port after drying or lock wind charging
Mechanism or discharging mechanism reduce the pollution to environment to prevent stink from leaking.
The air-distribution device is multiple, is connect with the hot-blast outlet of the circulating fan by air hose, the circulating fan
Hot wind inlet be connected by pipeline with the heat exchange air outlet of the gas-to-gas heat exchanger.
The garbage conveyor structure 7 is realized using existing step-transit conveyor, in forward transmission process
Rubbish is dried by hot wind.
Specifically, Temperature and Humidity device can also be arranged in the drying room, such as hygrometer and thermometer, Temperature and Humidity
Device connects controller, the controller and the driving mechanism of the garbage conveyor structure and the controller phase of the circulating fan
Connection.It is built in the indoor temperature and humidity measure device of drying, rubbish conveying speed and cloth air quantity can be effectively controlled, reach
The purpose for making rubbish evenly drying be dehydrated.It is provided with hygrometer and thermometer in drying room 3, is adjusted according to the humidity in hot-air
The volume of air supply of 8 each region of fltting speed and arrangement apparatus of whole garbage conveyor structure 7.
In specific implementation, the hot air source that waste heat is formed occupies this hot air circulation garbage dewatering device side, including gas-gas heat exchange
Device, circulating fan.Gas-to-gas heat exchanger uses cement kiln head waste gas residual heat for heat source heat drying circulation air, by circulated air
