Improve further:
Described mud dehydrator also includes for the filter press of sludge dewatering and for carrying the conveying of mud
Machine, the mud after filter press dehydration is transported to sludge dryer through conveyer dries.
This utility model use technique scheme, round-the-clock running can be accomplished, when outside air temperature relatively
Gao Shi, utilizes air energy drying, provides heat by air source heat pump to dehydrator；When outdoor air is relatively low
Time, utilize water energy, provide heat by water resource heat pump to dehydrator；When underground water temperature is less than sewage disposal
During the temperature of plant effluent, water resource heat pump is utilized to reclaim the waste heat in sewage disposal plant effluent.Utilize dehumidifying waste heat
Retracting device absorbs sensible heat and the gasification latent heat of damp-heat air in mud drying course.
This utility model can use air energy and water can carry out mud drying simultaneously, also is able to utilize dirt simultaneously
Water outlet waste heat in water treatment plant's carries out mud drying, and operating cost is low, pollution-free, energy-saving and environmental protection.
Below in conjunction with the accompanying drawings the technical solution of the utility model is described further.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
In figure: 1-water source heat pump system；2-air source heat pump system；3-sludge dryer；4-condenser；
5-expansion valve；6-dehumidifies heat reclamation device；7-compressor；8-filter press；9-conveyer.
