1. It adopts steam heat transfer medium, which can be used in semi-drying process or full-drying process. The system is simple and the auxiliary equipment is few.
2. Set the air supply port to make the exhaust gas discharge smoother, and the exhaust gas treatment system has a small load.
3. High reliability, good continuous operation, day and night operation, suitable for drying materials with long processing capacity.
4. The steam does not come into contact with the sludge, and the amount of insoluble gas in the exhaust gas is small, which can be incinerated in the furnace, and the secondary pollution is less.
5. The oxygen content, temperature and dust concentration are low during operation, and the system is safe.
6. The drying machine transfers heat through the outer wall of the outer casing, the hollow shaft and the left and right sides of each vertical disc, and has a large heat transfer area, compact structure and small outer dimensions.
7. The sludge inside the dryer is wet sludge. In order to prevent the sludge from sticking to the turntable, there is a fixed long scraper on the inner wall of the outer casing, which extends into the gap between the discs to stir the sludge and clean the surface. effect. After the sludge is crushed and agitated, it is evenly granulated, which is beneficial for further disposal.
8. Heating with a low temperature heat source (≤170 °C), the sludge on the disc will not overheat when parked, and the restart will not be affected.
9. The sludge treatment load is large, and even if the feeding is uneven, the smooth operation can be ensured, the internal running resistance is small, and the equipment energy consumption is low.
10. Simple maintenance, continuous operation, day and night operation, guaranteed to run 8000 hours per year.
