Working principle of sludge treatment equipment

The high humidity sludge is sent directly into the roller crushing dryer by the feed spiral, and the copy plate on the inner wall of the roller is repeatedly copied and dropped. After the crushing device is scattered, the material is in full contact with the high temperature medium under the negative pressure to complete the heat and mass transfer process. Because of the inclination of the roller and the effect of the introduction of the air, the material is slowly moved from the feed end, and it is discharged by the helix of the material after drying. The tail gas is discharged through the dust collector and discharged into the atmosphere.
The sludge treatment equipment adopts a flow drying process, especially for the rapid drying of the high wet sludge which needs to be preserved. For example, the treatment of fresh chicken manure can be used to dry, sterilize, deodorize and preserve nutrition at a time. The machine is equipped with a high-speed rotary crushing device, which increases the contact area of the sludge and the drying medium, and a certain inside of the equipment. Some unique designs make the sludge not easy to adhere to the operation board and cylinder wall. The whole machine has good thermal insulation and sealing performance, and its thermal efficiency is much higher than that of the ordinary roller dryer.
The sludge treatment equipment is compact in structure, easy to install and debug, and occupies small area. The roller and crushing device all adopt stepless speed regulation, which can meet the drying requirements of different materials. The machine can be used with the heat source of different fuel (such as coal, heavy oil and natural gas).
