Printing and dyeing (living, chemical, calcium carbonate) sludge dryer
Project description and advantages:
Many chemical companies' sewage treatment plants pull the sludge from the belt filter outside the plant and dump it, polluting the surrounding environment. Now the state has banned sludge dumping. Therefore, the company needs to dry the sludge and burn it or give it to building materials. For factory bricks. Therefore, sludge drying will become a project with great potential in the future. The hollow blade dryer developed by our company is especially suitable for sludge drying! Now many chemical companies have been widely used.
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 per unit effective volume is large, and the temperature of the heat medium is from 40 ° C to 320 ° C. It can be water vapor, hot water or thermal oil. The heat transfer medium flows through the shell jacket and the hollow stirring shaft through the rotary joint. The hollow stirring shaft has different internal structures according to the type of the heat medium to ensure the best heat transfer effect.
While the blades and jackets are heated by steam, the upper part of the outlet is simultaneously heated by dry air to further dry, which greatly increases the drying strength of the equipment. The evaporated water is taken out of the dryer by the tail gas, filtered by a bag filter, and the dried fine powder is recovered. The wet air is removed by water and the fan is discharged to the outside.
