Material Description:

Electroplating sludge refers to the sediment generated during the treatment of electroplating wastewater, mainly composed of heavy metal hydroxides such as copper and chromium, with complex components. Due to the large amount, complex composition, high COD, and high heavy metal content of electroplating wastewater, if discharged without treatment, it can lead to serious environmental pollution. During the treatment of electroplating wastewater, a large amount of electroplating sludge will also be formed, which has high moisture content, high thermal stability of heavy metal components, and easy migration. If not properly treated, it can easily cause secondary pollution.

Product Name: KJG series hollow blade dryer

summary:

Wedge shaped hollow blades are densely arranged on the hollow shaft, and the heat medium flows through the blades through the hollow shaft. The heat transfer area within a unit effective volume is large, and the temperature of the heat medium ranges from -40 ℃ to 320 ℃. It can be steam or liquid, such as hot water, thermal oil, etc. Indirect conduction heating does not carry away heat with air, 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 device body. The wedge-shaped blade heat transfer surface has self-cleaning function. The relative motion between the material particles and the wedge-shaped surface produces a scrubbing effect, which can wash away the attached material on the wedge-shaped surface and maintain a clean heat transfer surface during operation. The shell of the blade dryer is W-shaped, and generally two to four hollow mixing shafts are arranged inside the shell. The shell has sealed end caps and upper caps to prevent material dust leakage and collect material solvent vapor. Set up a stopper at the discharge port to ensure the height of the material level, so that the heat transfer surface is covered by the material and fully functional. The heat medium flows through the shell jacket and hollow stirring shaft through the rotary joint. The hollow stirring shaft has different internal structures depending on the type of heat medium to ensure heat transfer efficiency.

Application:

The paddle dryer has been successfully used in fields such as food, chemical, petrochemical, dye, and industrial sludge. The characteristics of heat transfer, cooling, and stirring of the equipment enable it to perform the following unit operations: calcination (low temperature), cooling, drying (solvent recovery), heating (melting), reaction, and sterilization. The stirring blade is also a heat transfer surface, which increases the heat transfer area per unit effective volume and shortens the processing time. The wedge-shaped blade heat transfer surface also has self-cleaning function. The compression expansion mixing function ensures uniform mixing of materials. The material moves in a 'piston flow' along the axial direction, and within the axial range, the temperature, humidity, and mixing gradient of the material are very small.
