As for industrial coal boiler heating enterprises,in the city of coal in the process of using the problem of pollution is one of the major problems of atmospheric pollution,as the country "twelfth five-year" plan will nox emission reduction as a key,denitration became desulfurization pollution control is one of the key tasks.Denitration technology research at home and abroad is mainly suitable for coal-burning flue gas denitration,for industrial boiler denitration without effective control measures,aiming at how to develop small cost of investment,low running cost,easy to use personnel operation,can effectively reduce industrial coal boiler NOx emissions technology research and analysis.Wet oxidation absorption process is determined,medicament adopt NaCLO2 +acid adjustment.In practical production on the basis of the desulfurization tower increases the denitration tower section,spray tower was studied to improve,the plate spray technology,main agents of denitration sodium chlorite has carried on the thorough analysis,and in the actual application are studied,the drug safe use and the theoretical study of the chemical related to obtain a certain conclusion.Determine the production of 7.5 ? NaClO2 solution,denitration ring temperature,denitration solution PH control effect,at the same time control the desulfurization solution PH at about seven.Established to ensure the integrity of operation in the operation of the denitration system and process,to ensure the nox emission standard of denitration sodium chlorite slurry using precise control,determine the solution concentration,PH value data can effectively guide the operation personnel operation,for trial and error,recorded a large amount of operational data,the data was analyzed through the denitration PH control is obtained reasonable operation,between 4 to 5 different boiler load dosage of sodium chlorite.Determines the industrial heating coal boiler with out of stock of the agent for the solution,through the operation of the oxidation absorption principle to achieve denitration,confirmed that the operability of this technology is very strong,and the original wet desulphurization equipment can better together,sold out in industrial heating coal fired boiler in the improvement and perfection has certain reference and popularization significance.
