3）Through 2）The further dedusting in fume high-temperature dust-extraction unit of the high-temperature flue gas of generation, and pass through high-temperature thermal storage type flue gas heat
Reuse heat storage cools down, and flue gas heat is stored in heat-storing material, and flue gas after cooling enters waste heat boiler and further cools down,
Generate low-pressure low-temperature steam；
4）Through 3）Cooling flue gas enters reacts depickling with acid gas absorbent in depickling reactor, and passes through bag-type dust
Device removes absorbent and flying dust；The de- ash collected of bag filter is flown into carries out the non-nothing of melting conversion into plasma ash melting furnace
Harmful vitreum；
5）Through 4）Purified flue gas removes dioxin, sulfide or other pollutants in advanced oxidation room, then through over-subtraction
Wen Tanei lye washing cooling, wet cottrell capture amounts of residual contamination, realize the deep purifying of flue gas；
6）Step 3）In generated low temperature and low pressure steam be passed into the hot reuse heat storage of high-temperature thermal storage type flue gas and be preheating to high temperature,
Blowback and cleaning high-temperature dust removing device, partly enter in plasma ash melting furnace, are partly directly entered the steaming of high temperature air water
Gas gasification furnace；Entrained ash particle melts in plasma melting furnace that be converted to harmless vitreum molten with flying dust bottom ash
Slag；
7）Step 5）In high temperature air/vapor higher temperature is preheated in plasma melting furnace, from gasification furnace bottom
Portion enters gasification furnace and participates in gasification reaction.
