Belt Type (Waste heat) Sludge Low Temperature Dryer

The functions of heat pump is replaced by waste heat (heating) and cooling water (dehumidification) in a waste heat type dryer. However, same advantages are kept as its heat pump counterpart. Moreover, electricity bills are cut due to utilizing free waste heat. Daily drying capacity ranges from 7.5 tons to 75 tons of standard wet sludge.

Layout of drying zone:

Belt type
 

Auxiliary equipment
wet sludge Feeder, wet sludge hopper, 
sludge anti-clog device, sludge slitting machine, 
dry sludge discharger, dry sludge hopper, 
cooling tower, cooling control cabinet 
 

Optional auxiliary equipment:

screw sludge dewatering machine.

 

Operation Mode:

Continuous drying (capacity: water 5000-50000kg/day) where waste heat is available.
 

Applicable dehydrating method:

flexible. Sludge forming test is required. 
 

Sludge Data: 

moisture content before drying: 83%-70% ; 

moisture content after drying : 60% -10% adjustable
 

Waste heat consumption: ~1kWh/kg H2O

There are 1 model 34-ton unit and 10 derived submodels for waste heat belt type dryer.
