No Noisy Low Temperature City Sludge Heat Pump Dryer

Product Description:
The product adopts a belt type of closed cabinet dehumidification heat pump drying. There is no need for additional energy (steam, thermal-conduction oil and hot-blast air), as well as no need for treatment system for tail gas.
The system can further reduce the water content to 10-30% adjustable as you wish.
Volume reduction is over 90%, saving your cost on sludge transfer fees



Product Structure

The system makes use of the dehumidification heat pump to carry out the sludge through hot-air recycling, condensing, dehumidifying and drying. The evaporation of the sludge moisture produces latent heat. And the condensation of vapor on the heat pump requires latent heat as well. Both processes of latent heat is equal according to the law of conservation of energy. As a result, the drying process does not require additional heat capacity. The energy consumed during the process is the electricity for the input to compressor, fan, and motor .

Working principle

Heat pump utilizes refrigeration system to cool and dehumidify hot and wet air, in the meantime, through the principle of heat pump, it recycles the latent heat released from steam congealing to water liquid. H eat pump = Dehumidification (moist dehumidifying) + heat pump (energy recycling). It can collect all the latent heat and sensible heat during air exhaust, bringing no waste heat to the outside.

System features

The whole equipment adopts closed running design, no odor out, no need to add expensive odor removal system. COD level of cooling water is low, easy to dispose.

The closed running design combines with heat pump heat recycling technology, no heat loss, more efficient and more advanced.

Adopting four-effect equipment, effectively reduce the operation cost, drying 83% water content wet sludge to 30%, the operation cost is low to 180kw.h/T.

All closed low temperature 40~75ºC running, dust density<60g/m³, oxygen<12%, no risk of raising dust and explosion. The outlet sludge temperature is below 50ºC, no need for cooling.

High-grade anti-corrosion materials, no wearing parts and no wearing during operation. Services lifespan is up to 15 years.

Pasteur sterilization technology, during drying, Escherichia coli can be killed over 90%.
