1. It is composed of a set of specially designed covered sludge Hopper, two sets of circulating air pipes and a drying unit, which can make the dry air penetrate and circulate efficiently between the wet sludge.

2. During the whole drying process, the sludge stays in Hopper for about 16~24 hours. The factors affecting the drying time include the concentration of the feed sludge and the pores of the feed sludge. The moisture content of the wet sludge cake is 70%. For example, the moisture content of the dried sludge cake is 30%, which can reduce the weight by 57%.

3. The dry cold air is heated by the waste heat generated by the operation of the compressor and then returned to the sludge cake drying tank, which not only increases the drying efficiency, but also does not need to use additional heating equipment. It is a very energy-saving and economical sludge dryer.

4. Because the return air dry air is only about 60~70°C, the odorous substances or other harmful substances in the sludge cake will not leak out with the air, so there is no need to use scrubbers, chimneys or other air pollution control equipment, which not only saves equipment Cost, and will not cause trouble in operation. In the same way, the condensate does not contain sludge and can be discharged directly.

5. Using the touch-sensitive man-machine interface, the setting of operating parameters is simple and easy.

6. This equipment uses a principle similar to that of a dehumidifier, and uses the characteristic of “the higher the temperature of the air, the higher the saturated water content”. The air passes through the condenser (heat exhaust), and the water content in the air will rise to In the saturated state, the high-temperature and high-humidity air is then cooled by the evaporator (cold exhaust), and the water in the air will be condensed due to the rapid cooling.
