Techase -Â Model TCDW -Low Temperature Sludge Dryer
Low temperature sludge drying technology is injecting circulating, warm and dry air to evaporate and take away the moisture in the sludge cake produced by sludge dewatering equipment such as multi plate screw press, plate and frame filter press, super high pressure filter press and so on to achieve the purpose of sludge weight reduction. It is suitable for Municipal sludge and Industrial sludge such as pickling sludge, electroplating sludge, steelmaking ironmaking sludge, alumina sludge (red mud), oily sludge from oil fields and refineries, chemical and pharmaceutical sludge, papermaking sludge, printing and dyeing sludge and leather sludge, sludge weight reduction capacity of more than 70%, thereby greatly reducing enterprise production costs.
- Over 70% of sludge reduction capacity
- Drying temperature is below 70°C, no danger of dust or explosion
- No need for polymer, the moisture content of sludge cake discharging can be flexibly adjusted
- High calorific value of dry material, conducive to subsequent resource utilization
Wet sludge is fed in low temperature sludge dryer after granulation, then the sludge is distributed evenly on the conveying track by sludge arranged distributor so that the moisture can be taken away by flowing air provided by circulating blower and finally realized discharge of the dry sludge; After the moisture taken away by the flowing air, the air is condensed at the condenser, the condensed liquid is discharged out of the equipment, and the condensed and dehydrated air is reheated by the heater, then reenter into the sludge, and cycling in this way; The refrigerant is compressed by the compressor after endothermic process of expansion of cooler, then the heat is released from the heater, the extra heat is removed through the radiator, the refrigerant is subsequently recirculated to the condenser. The radiator in this process can be air-cooled or water-cooled in order to strengthen heat dissipation. There are multiple sets of temperature, pressure and humidity sensors in the low temperature sludge dryer to monitor and automatically adjust the operation of the device to ensure the dryness of the sludge discharge.
