| In recent years,the fog and haze is getting worse and worse,causing the attention of the state environmental protection department,the environmental protection department also put forward higher requirements for particulate emissions.This requires the transformation of the original dust removal equipment to meet the requirements.The technology of chemical agglomeration is a kind of technology with low cost and good effect,which can meet the requirement of power plant.On the basis of a coal-fired power plant 300MW unit.First of all,on atomization Sauter mean diameter influence factors of chemical agglomeration special nozzle system are studied.The research results show that the Sauter mean diameter of atomized particles decreases with decreasing nozzle diameter,with the increase of air pressure decreases,and increases with the increasing of water flow;Then,through the monitoring data of CEMS power plant,studied the effect of chemical aggregation technology concentration and particle dust removal process after the flue and power plant desulfurization process flue NOx content,SO2 content and O2content in the application process.The results show that the chemical agglomeration technology has a better effect on reducing particulate in the flue gas.This paper analyzes the data of the 168 hour operation of the chemical agglomeration system in power plant.It can be found that the chemical agglomeration system and the original equipment of the power plant can run smoothly.Finally,sampling and testing in the power plant.The purpose of the experiment is to verify the effect of chemical agglomeration technology on PM2.5 in flue gas of power plant.The sampling position is located in the flue gas after dust removal and desulfurization.The results show that the average removal efficiency of PM2.5 in flue gas is 23.92%,and the average removal efficiency of PM2.5 is 42.90%in desulfurization.It can be verified that chemical agglomeration technology has a role in reducing emissions of PM2.5. |
