Abstract
The utility model discloses a multi-stage decentralized treatment type sludge low-carbon drying device, and belongs to the technical field of sludge treatment. The multi-stage decentralized treatment type sludge low-carbon drying device comprises a drying box and an air return box, the drying box and the air return box are communicated with each other, a material scattering hopper is arranged at the top of the air return box, a material falling pipe at the bottom of the material scattering hopper extends into the air return box, and a cutting blade is arranged in the material scattering hopper. In order to solve the problems that in existing sludge treatment, sludge subjected to high-pressure dehydration can be agglomerated and caked under the influence of pressure, so that water is not easy to completely evaporate in the subsequent drying process, and the agglomerated and caked sludge is also very inconvenient to convey, a multi-stage dispersion mechanism is linked with one another and is progressive layer by layer, and the efficiency is high. Sludge blocks with different sizes and hardness are effectively crushed into fine particles, and the specific surface area of the sludge is greatly increased in a loose particle state, so that water is easier to migrate to the surface and evaporate.
