Abstract: New type wasteheat recovery,wet method desulfurization and dust removal technology (NDD method) is an integrated technology,which including waste heat recovery facility,gravitational dust collection facility,and wet method desulfurization dust removal facility.It was developed by summing up a lot of experiences of desulfurization and dust removal from many Chinese akali sulfide enterprises.Based on the principles of wasteheat recovering,akali sulfide wastewater recycling (treatment of wastes with processes of wastes against one another) as well as desulfurization and dust removing by wet method,hard-nut problems had been tackled on the strength of science and technology.Practice has proved that this whole set of technology has good application effect,investment is less，and running cost is also very low.Waste heat recovery technique has improved the process of akali sulfide and product quality.Running of desulfurization and dust removal was simple and reached the environmental protection goal.
