Shincci Heat Pump Sludge Dryer SHS Series

Technology

Shincci™ Low Temperature Sludge dryer can achieve sludge volume reduction, stabilization, sterilization, and reutilization. Its outlet dried sludge granule can be disposed with gasification, blended-burning, incineration; can be utilized as biofuel, construction material, cement material and landfilling material; It is applicable to transform any type of dewatered sludge (10% minimum dry content) into a dry, such as municipal, printing, dyeing, papermaking, electroplate, chemical, and leather, granulated product with a dry-solids content that can be adjusted within a range of 15% to 90%.


Working principle


SHS INTEGRATED BELT-TYPE SLUDGE DRYER. The dryer adopts direct low temperature drying. Direct low temperature drying makes hot effect on sludge, producing high thermal efficiency. Moreover, low temperature protects organism in the sludge from splitting and volatilization, while the circulation hot wind takes only water out from the sludge.


Shincci drying temperature is 45-50℃ (temperature of the recycle to dehumidification heat pump), while blowing-in temperature is 60-75℃ (bottom layer).


Dehumidification heat pump sludge dryer makes use of dehumidification heat pump to carry out the sludge through hot-air recycling, condensing, dehumidifying and drying. The evaporation of the sludge moistureproduces latent heat. And the condensation of vapor on heat pump requires latent heat as well. Both process of latent heat is equal according to the law of conservation of energy. As a result, 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.


This dehumidification dryer is equivalent to the combination of dehumidification heat pump and mesh belt conveyor (playing the role of sludge placement).


The hot dry air flows through wet materials and takes away moisture thus becomes hot wet air, which then passes through the cold end of heat pump and condenses the absorbed water (dehumidification). The cold dry air after dehumidification is then heated by the hot end of heat pump and becomes hot dry air (energy recovery). A new cycle starts.

Feature

  • Heat pump, Mesh belts and Insulation boards are all combined in one integrated module, which improves airtightness and makes onsite installation easier.
  • Expansion valves adopted electronic type to increase dehumidification capacity.
  • Heat exchangers and Refrigerant pipes are made of SUS316L instead of copper.
  • Compressors are all installed in independent chambers, well- protected from the corrosive-gas to extend their service life.
  • Two modules share one blower, and the belt-driven type blower is installed in the Heat pump module instead of the mesh belts module, which makes cleaning and maintenance easier.
  • Standard operation consumption is 240~300 kWhr/1ton.H20 (MAX).
  • SUS316L base of dryer replacing aluminum alloy support, making sure a strong anti-corrosion performance.
  • The service access door are upgraded to quick-opening type and improved with unique airtight structure design, making maintenance and inspection easier and effectively door.

 

EFFICIENCY

  • Sludge moisture content can be reduced from 80% to 10% (20% to 90% Solids), adjustable as required.
  • Sludge volume can be reduced by 67% and weight by 80%, this results in 1 truckload to be hauled where there used to be 5.
  • Optimized evaporation efficiency, available to automatically operate 24/7 with minimized operator attendance.        


SAFETY

  • Low processing temperature of 40-75℃ in a closed cabinet ensuring long-term disposal safety.
  • Outlet Sludge<50℃ requiring no need for secondary cooling which allows it to be stored directly.


ENVIRONMENT

  • Sustainable and eco-friendly process, with enclosed design to minimize odor emission.
  • Available to be built inside the factory for sludge centralized processing.
  • The clear condensate water from the drying process can directly drain to sewage pool without any secondary treatment.


INNOVATION

  • The dehumidification capacity reaches as high as 4.5kg.H2O/kW.h, which is the world’s leading technology standard.
  • Energy-consumption saved by 50% compared to the current industry standard.


ECONOMY

  • The energy consumed during the process is only the electricity needed to operate the compressors and the fans or air handlers.
  • The electric energy demand for drying sludge moisture content from 80% to 30% is only 160 kW.h/T.


STERILIZATION

  • With pasteurization (low-temperature heating sterilization) at 70℃ drying for 90-120 minutes, it can sterilize over 90% bacteria effectively.
