AI Technical Summary

Technical Problem

Existing sludge harmless treatment equipment cannot meet the requirements of a safe, green, low-carbon, and effectively regulated sludge harmless resource utilization system for municipal construction. Moreover, sludge treatment costs are high, heat energy consumption is large, and heat cannot be effectively recovered and utilized.

Method used

The mechanical cold-press sludge treatment device includes a sludge mechanical cold-press deep dewatering system, a dried sludge incineration waste heat recovery system, and a flue gas purification system. The sludge is dewatered and dried at room temperature through mechanical cold-press technology, and the dried sludge is incinerated using a bubble fluidized bed incineration to recover incineration heat for power generation or heating.

Benefits of technology

It achieves ambient temperature dehydration and drying of sludge, reducing treatment costs, and realizes resource-based disposal of sludge through heat recovery, avoiding the release of high-concentration odor and meeting environmental emission requirements.
