Sewage sludge hollow paddle dryer Sludge drying equipment

Description of hollow paddle dryer: Hollow Paddle Dryer can indirectly heat or cool the materials in paste, granules, powders and slurries. It can also complete the unit process of drying, cooling, heating, sterilization, reaction and low temperature combustion. the special heat-transfer stirring blade wedge type in the equipment has high heat-transfer efficiency and its heat-transfer surface has self-cleaning function. A hollow shaft is densely arranged with hollow wedge-shaped blade; heat medium flow to the hollow blades through hollow shaft. the heat transfer area per unit effective volume is large. Temperature of heat medium is from -40 ºC to 320 ºC, may be in the form of water vapor or liquid, such as hot water or heat transfer oil. Indirect conduction heating has no air to carry away the heat, so the heat is all used to heat the material, and the only heat loss is the heat dissipated around from the heat insulation layer. Heat-transfer surface of wedge-shaped…
