Description

Technical Field

[0001] The utility model relates to the field of sludge treatment, in particular to a dehydration and drying device for sludge treatment. Background Art

[0002] Sludge is a product of sewage treatment. It is an extremely complex heterogeneous body composed of organic debris, bacterial cells, inorganic particles, colloids, etc. The main characteristics of sludge are high water content (up to 99% or more), high organic content, easy to rot and stink, fine particles, low specific gravity, and colloidal liquid. It is a thick substance between liquid and solid, which can be transported by pumps, but it is difficult to separate solids and liquids by sedimentation.

[0003] Sludge dewatering is an important part of the entire sludge treatment process. Its purpose is to enrich the solids, reduce the sludge volume, and create conditions for the final disposal of the sludge. In order to separate the liquid phase and the solid phase of the sludge, the binding force between them must be overcome. Sludge dewatering and drying include natural dehydration, mechanical dehydration and thermal treatment drying. However, in the current equipment used for sludge dewatering, the sludge moves on the conveyor belt. When it is dried by hot air, the surface of the sludge can be dried and dehydrated, but the inside of the sludge cannot come into contact with the hot air, resulting in low dehydration efficiency and poor effect.
