Abstract
The invention provides a multi-effect sludge drying chamber, and belongs to the technical field of sludge drying. According to the technical scheme, sludge moves downwards along with a conveyor belt in sequence in vertical space and keeps in contact with countercurrent hot air constantly in the process, and accordingly the drying area of the sludge and the use ratio of the space are effectively increased. Meanwhile, exhaust gas waste heat, condensed water heat release and solar radiant heat are combined, the energy consumption level is remarkably reduced. Besides, sludge conveying and air flowwaftage are both completed in a mechanical way, and thus the automation degree is high, and human resources are saved. On that basis, if a detection unit and an electronic control unit are further introduced, automatic control over the device can be implemented. Exhaust gases after treatment are collected collectively, and secondary pollution to the environment is avoided. The multi-effect sludgedrying chamber achieves a good technical effect through novel technical improvement and is reasonable in structure, the scheme adapts to local conditions, and the drying chamber has a wide application prospect.
Description
Technical field [0001] The invention relates to the technical field of sludge drying, and further relates to a sludge drying treatment equipment, in particular to a sludge multi-effect drying room. Background technique [0002] Sludge is the product of sewage treatment, and it is an extremely complex heterogeneous body composed of organic debris, bacterial cells, inorganic particles, and colloids. Its water content is extremely high. Calculated with a water content of 97%, its volume accounts for 0.3% to 0.5% of the treated sewage. If advanced treatment, the mud yield will increase by 50% to 100%. It is large in size, difficult to store, and has a big peculiar smell. , Serious pollution and other problems. In this case, if it is not dried and reduced, the subsequent transportation and processing links will be difficult to carry out. [0003] In the prior art, the drying methods of sludge mainly include: natural drying, thermal power evaporation, large-area board room drying or dr...
