Secondary pollution.
Brief description of the drawings
Fig. 1 is overall schematic of the invention；
Embodiment
The present invention is illustrated with reference to the accompanying drawings and detailed description.
As shown in figure 1, the present invention is a kind of new pig farm sludge treatment equipment, it is by apparatus body, wet mud charging aperture
1st, sludge single lead screw ex truding briquetting machine 2, sludge conveyer belt 3, hot pump in low temp 4 and dewatered sludge discharging opening 5 are constituted, and described sludge is squeezed into
Type machine 2 is arranged on the bottom of wet mud charging aperture 1, and sludge conveyer belt 3 is arranged on the lower section of sludge single lead screw ex truding briquetting machine 2, and sludge is defeated
3 are sent to carry three layers, the side of first layer sludge conveyer belt 3 is provided with circulating fan, and hot pump in low temp 4 is arranged on sludge conveyer belt 3
Side bottom, be provided with regenerator in hot pump in low temp 4, the top of sludge conveyer belt 3 is provided with evaporator and condenser, steam
Hair device is connected by compressor with condenser, and condenser is connected by expansion valve with evaporator, condenser and dewatered sludge discharging opening
5 connections, dewatered sludge discharging opening 5 is placed in the bottom of the side of apparatus body and wet mud charging aperture 1 is set in diagonal.
Hothouse and drying machine are provided with described hot pump in low temp 4.
It is set between described hothouse and drying machine closed.
Described sludge conveyer belt 3 is made up of at least 2 layers Teflon material.
Described evaporator is internally provided with low pressure refrigerant.
The present invention operation principle be：Sludge enters sludge single lead screw ex truding briquetting machine 2 by wet mud charging aperture 1, is extruded
Shaping makes sludge into fine strip shape, it is ensured that sludge has preferable ventilation on sludge conveyer belt 3, and fine strip shape is easier to make at drying
Reason, improves drying efficiency；First layer sludge conveyer belt 3 is then gone through, the hot blast that hot pump in low temp 4 is produced is defeated by third layer sludge
Send band 3 to enter second layer sludge conveyer belt 3 and enter back into first layer sludge conveyer belt 3, evaporator is then delivered to by circulating fan again,
Condenser carries out dehumidifying heating.Moisture percentage in sewage sludge on first layer sludge conveyer belt 3 is higher, in first layer sludge conveyer belt 3
Side increase circulating fan to first layer sludge conveyer belt 3 carry out hot air circulation, carry treatment effeciency.
Present invention air when hot pump in low temp 4 is dried carries out closed cycle between hothouse and drying machine, and it utilizes drying
The refrigeration plant of machine makes the humid air cooling dehumidification from hothouse, when humid air stream is through evaporator, internal low voltage refrigeration
The heat of agent absorption air is changed into gaseous state from liquid, and air discharges most of condensate therein because of cooling.Carry out flash-pot
Low voltage refrigeration steam by compressor boost after deliver to condenser.It is internal when the cold dry air after dehumidification flows through condenser
High-pressure refrigerant releases heat because of condensation, and outside air is then heated to be hot blast and is returned to required for hothouse continuation drying
Dry product.Evaporator, which is flowed into, after the expanded valve decompression of high-pressure refrigeration liquid flowed out from condenser continues next circulation.
It is to increase regenerator in the drying machine of hot pump in low temp 4 that the heat-pump dehumidification of the present invention, which dries extraction cycle, makes entrance
The air themperature of evaporator declines and the air themperature for condenser of entering rises；Extraction cycle makes evaporator cold be dropped for air
Temperature is reduced, and is used for the increase of cool-down dehumidification process cold, the optimal evaporation temperature and optimal moisture removal of heat pump drying is increased；Increase
The heat-pump dehumidification of add-back thermal cycle is dried than common heat pump drying energy saving more than 30%.
