摘要
选用(NH_4)_2SO_3溶液为吸收液,在鼓泡反应塔内对NO的吸收特性进行实验研究,探讨了(NH_4)_2SO_3的溶液浓度、NO浓度、气体流量、温度和SO_2浓度等对NO脱除效率和吸收容量的影响。研究表明,NO脱除效率和吸收容量随着(NH_4)_2SO_3溶液浓度和NO入口浓度的增加而增加,随着入口气体流量的增大而减小。而随着温度的升高,NO脱除效率和吸收容量先增加,到达50℃时达到最大值,温度继续升高,NO脱除效率和吸收容量逐渐下降。SO_2的存在对NO脱除效率和吸收容量有一定的促进作用。分析了(NH_4)_2SO_3还原脱除NO机理,研究结果为氨法脱硫系统增加脱硝功能提供了实验基础。
The selection of （NH4） 2SO3 solution as absorption liquid, at NO bubbling reaction tower on experimental study on the characteristics of absorption, discusses the solution of （ NH4 ） 2SO3 concentration, NO concentration, gas flow rate, temperature and SO2 concentration on the NO removal efficiency and the influence of absorptive capacity. Research shows that the NO removal efficiency and with （ NH4 ） 2SO3 absorption capacity increased with increasing solution concentration and NO entrance concentration, and decreases as the inlet gas flow. And with the increase of temperature, the NO removal efficiency and absorption capacity increased first and reach maximum arrived at 50℃, the temperature continues to rise, the NO removal efficiency and decrease its absorption capacity. The presence of SO2 on the NO removal efficiency and absorption capacity has a certain role in promoting. Analyzed the （NH4） 2 SO3 reductive removal NO mechanism, the results of the study for ammonia desulphurization system increases the denitration function provides the experimental basis.
