Abstract

The invention relates to a sludge vibrating mixing spouted bed drying device and a sludge vibrating mixing spouted bed drying method. The sludge vibrating mixing spouted bed drying device provided by the invention comprises a dryer body (1), an inner cylinder (2), a mixing device (4), a spring component (6), a vibrating motor (8), a wet sludge inlet (3) and a heat medium inlet (5), wherein the dryer body (1) is divided into an upper part, a middle part and a lower part and provided with a top wall; the inner cylinder (2) is arranged on the upper section in the dryer body (1); the mixing device (4) is arranged on the lower part in the dryer body (1); the spring component (6) is used for connecting the dryer body (1) with the inner cylinder (2); the vibrating motor (8) is arranged outside the top wall of the dryer body (1); the wet sludge inlet (3) is used for inputting wet sludge into the dryer body (1) and is formed in the middle of the dryer body (1); and the heat medium inlet (5) isused for inputting heat media into the dryer body (1) and is formed on the lower part of the dryer body (1). The device has the advantages of continuous operation, low labor intensity, high production efficiency and low heat dissipation.

Description

technical field [0001] The invention relates to a sludge drying device and a drying method. Background technique [0002] Sludge is the product of sewage treatment. Due to its high water content, complex composition, and more organic matter, it has a certain viscosity. At present, the disposal methods of sludge are mainly landfill and composting. Landfill disposal method will occupy a large amount of land resources and easily cause secondary pollution. According to the methods of sterilization and aging, compost has different fertilizer efficiency and safety. This disposal method can achieve the purpose of recycling, but the processing process is longer, and it will also occupy a large amount of land resources, and the disposal cost is also high; in addition, Sludge containing harmful components such as heavy metals should not be disposed of in this way. [0003] After drying, the sludge can be greatly reduced, harmless and resourceful. The dried sludge can be used as raw...
