Overview: Most of the sludge is organic and inorganic substances precipitated from urban domestic sewage and industrial chemical wastewater treatment plants. Due to the malodorous gases, pathogens, organic substances and heavy metals in the sludge, traditional composting and sanitary landfill technologies have been unable to meet today. The requirements of sludge disposal, and incineration as one of the sludge disposal methods, because of its fast speed, small footprint, short storage time, environmental protection completely meet the standard and no secondary pollution and other significant advantages have become the current main direction of sludge disposal First, because the sludge requires high thermal energy for incineration, and the general sludge moisture content of 75-85% is not economical, it is necessary to use waste heat from an external heat source or dry and dehydrate the sludge before Incineration.

use

1. Factory sludge and sludge produced in petroleum, chemical, textile, pesticide and other industries;
2. Sludge from urban sewage treatment plant.

Process flow



Structural features

1. The dryer is suitable for waste heat utilization. The commonly used machines are paddle drying, drum drying, belt drying, and disc drying.
2. The thermal drying source can adjust the moisture content of sludge from 80% to 30% flexibly;
3. The absolute dry heat value of the sludge after drying can fully meet the needs of thermal incineration and greatly reduce the system operation cost;
4. The incineration process uses rotary kiln or fluidized bed incineration process, and the environmental protection treatment meets the standards;
5. Integrated drying and incineration, compact equipment structure, occupying a small area. Economic and reasonable operating costs.
