AI Technical Summary
Sludge drying systems suffer from high energy consumption, high operating costs, and additional pollution problems. In existing technologies, the selection of heat sources for sludge drying leads to a decrease in boiler thermal efficiency and an increase in corrosion risk, while the cost of treating condensate wastewater is high.
Design a flue gas waste heat recovery system based on a sludge co-firing power plant. The system uses the condensate wastewater generated by the condenser as an intermediate heat transfer medium, and combines the waste heat from the boiler exhaust as a primary heat source for sludge drying. The system achieves flue gas waste heat recovery through indirect heat exchange and combines it with energy cascade utilization to synergistically achieve sludge drying, clean treatment and reuse of condensate wastewater.
It reduces energy consumption in the sludge drying process, saves on condensate wastewater treatment costs, and improves the desulfurization operating conditions, resulting in good economic and environmental benefits.
