The new sludge paddle dryer is aimed at the disadvantages of traditional sludge dryers such as high energy consumption, serious air pollution, and large investment in waste gas treatment environmental protection equipment. After years of research and development, our company has successfully developed an energy-saving heat pump paddle dryer. The equipment provides a complete set of assembly line devices, including: sludge conveyor, hollow blade dryer, heat pump dehumidifier, discharge conveyor, etc., to meet the user's automatic production, clean environment, no waste gas emission pollution, waste heat recovery, and large processing volume Requirements. The system has high stability and can be effectively connected with heat transfer oil, solar energy, boilers, steam and other systems. It is a new energy-saving device for sludge drying.
Wedge-shaped hollow blades are densely arranged on the hollow shaft of the special hollow blade dryer for aluminum hydroxide. The heat medium flows through the blades through the hollow shaft. The heat transfer area in the unit effective volume is large, and the temperature of the heating medium ranges from -40°C to 320°C. It can be steam or liquid: such as hot water, heat transfer oil, etc. Indirect conduction heating, no air is carried to take away the heat, and the heat is used to heat the material. The heat loss is only the heat dissipation to the environment through the insulation layer of the body. The wedge-shaped blade heat transfer surface has a self-cleaning function.
