Continuous hollow screw drying complete equipment is mainly used for municipal sludge and industrial sludge drying reduction treatment. After the sludge is mechanically dewatered by screw stacking or filter press, the moisture content reaches 60% ~ 85%. The dewatered sludge is further dried by this equipment to reduce the moisture content below 30%, and then transported or finally disposed. It can reduce the burden of freight and the pressure of disposal. The equipment can be used in a variety of heat sources. The heat exchange medium can be steam or thermal oil. The heat source can be the waste flue gas of the enterprise, the remaining water vapor of the process link, or the steam (heat conduction oil) boiler. The equipment is mainly developed and designed for centralized processing stations, petrochemical enterprises and other large-scale waste production, and at the same time there is a large amount of waste heat that can be recycled and used. It is suitable for building large-scale comprehensive processing stations.
By selecting different module combinations, it can adapt to materials with various properties.
The heat exchange efficiency of the main engine can be more than 80% only by internal heating and thickening external insulation.
With double spiral meshing structure, the equipment runs stably and can always maintain a high heat transfer coefficient.
The whole process system adopts the fully closed structure, maintains the micro negative pressure working condition in the system, and the pressure and temperature monitoring points are linked and controlled
The system can realize automatic operation, remote centralized control and 24-hour unattended.
