Application:
Waste treatment in the Chemical industry, chemical fiber and urban living industries
Working principle：
Sludge drying and incineration treatment production line is composed of sludge drying system, sludge incineration system, sludge collection,storage and transportation system, waste gas and wastewater treatment system, and automatic control system. Dehydration sludge drying and incineration treatment technology is widely promoted because of its thorough disposal, less land occupation, strong independence and integrity.
Sludge spray drying technology and sludge circulating fluidized bed incineration technology will dry the sludge with a moisture content of more than 70% to about 30%. After drying, the sludge goes through the circulating fluidized bed incineration, and the high temperature flue gas generated by incineration is used for sludge spray drying, making full use of the calorific value of the sludge. It is an clean combustion technology, which is investment saving, low cost of efficient energy saving, friendly environment etc, with obvious technical advantages.
Dehydrated sludge has a high moisture content, need to dry first and then burn, incineration flue gas temperature to drop sharply, fly ash capture, dioxin and heavy metal adsorption treatment;
In order to prevent secondary environmental pollution in sludge incineration process and prevent dust, toxic and harmful gas in exhaust gas, dust removal, acid removal and deodorization treatment are required; in order to prevent dust and mixed explosion of volatile gas in sludge drying process, effective explosion-proof measures should be taken;
The productive waste liquid caused during sludge drying and incineration need sewage treatment; the residue produced by sludge incineration shall be identified as building materials or landfill treatment. Therefore, the sludge drying and incineration system is the optimization and system integration of sludge drying, incineration, waste gas and wastewater purification treatment and other processes. Among them, sludge drying and sludge incineration process is the key to the whole system.
Main performance and features:
The core value of sludge spray drying and fluidized incineration treatment technology lies in the recycling after sludge drying, which greatly reduces the equipment investment and treatment and operation cost, has obvious economic and environmental advantages:
★ Process simple and high degree of automation;
★ Equipment composition less and small land occupation;
★ project investment saving and low operation cost;
★ secondary pollution is small, high comprehensive utilization rate.
