Development and Application of Flue Gas Waste Heat Evaporation Technology for Boiler Desulphurization Wastewater Treatment
In view of the problem that it is difficult to absorb high-salt and high-ammonia nitrogen desulphuri-zation wastewater with "near zero" discharge of sewage from refining and chemical enterprises,a flow model of direct evaporation of desulphurization wastewater with boiler flue gas waste heat was developed,and numerical simulation studies and pilot experiments were carried out on the effects of wastewater droplet particle size,at-omization angle,smoke velocity,smoke temperature and other variables on the droplet complete evaporation time and evaporation distance. The industrial structure design of flue evaporation chamber was completed,and the reasonableness and feasibility of the technology were verified through two stages of wastewater industrializa-tion trial run. The problems in the process of trial oper-ation were analyzed and evaluated objectively,the nec-essary rectification measures were put forward,and a new way of low cost,low energy consumption and envi-ronmental protection treatment of desulphurization wastewater was created.
