Sludge dewatering machinework process:
Sludge process: Wet sludge is made into granules or noodles by a granulator, extruder, etc., and spread on the mesh belt, and is continuously dried by hot air as the mesh belt moves, and then the dry material is discharged.
Air flow: dry hot air sweeps the surface of the sludge upward from the bottom, evaporates the moisture in the sludge to form moist air and enters the dehumidification heat pump. The heat pump system converts the moist air into dry hot air and continues to blow the sludge, resulting in condensate No exhaust gas is emitted during this process.
Refrigerant process: Use the refrigerant to circulate in the evaporator, condenser, compressor and expansion valve to realize the cooling, dehumidification and reheating of the humid air.
Technical features: sludge reduction
Safety and health: The operating temperature of the sludge dryer is lower than 70℃, and there is no hidden danger of dust and explosion; the temperature of the dry material is lower than 50℃, and it can be directly stored and transported; the sterilization rate is more than 90%, and the dry material is not easy to decompose.
Environmentally friendly: airtight and dry, no exhaust, no odor leakage; integrated thermal insulation design to avoid problems such as running and dripping; simple condensate treatment.
High efficiency and energy saving: all the energy of the sludge dehydrator is recycled by the heat pump system.
Wide applicability: suitable for sludge with a moisture content of 60%-85%; sludge weight reduction can reach 80%; dry material moisture content is adjustable from 10% to 50%.
Reliable and durable: The core refrigeration components (compressors, expansion valves, etc.) of the sludge dryer are isolated from the air duct to avoid component corrosion; there is no mechanical static wear, and the service life is more than 15 years.
Convenient and saving: The sludge dewatering machine occupies a small area, and the civil construction cost is low; the installation and debugging cycle is short, and the operation and maintenance is simple; fully automatic operation, low labor cost.
