聚丙烯酰胺复配物在自激式除尘器中的应用

为了提高自激式除尘器对呼吸性粉尘的去除效率，同时降低除尘能耗，将聚丙烯酰胺（PAM）、琥珀酸二辛酯磺酸钠（AOT）、硫酸钠和氢氧化钠或盐酸溶液进行复配，形成的PAM复配物用于自激式除尘器，对除尘情况进行了相关研究．从理论上分析了该复配物的除尘降阻机理，分别使用纯水、AOT溶液和PAM复配物溶液在自激式除尘器中进行了对比试验．结果表明，自激式除尘器使用PAM复配物溶液不但可以提高全尘特别是呼吸性粉尘的除尘效率，而且降低除尘器的阻力损失，减少能耗，在相同除尘效率和处理风量下，自激式除尘器使用PAM复配物溶液比使用纯水更经济、合理．

Application of polyacrylamide complexation on self-swash dust catcher

In order to enhance the efficiency of eliminating respirable dust and to reduce the energy consumption in self-swash dust catcher,the properties of self-swash dust catcher which uses complexation of polyacrylamide(PAM),sodium dioctylsulfosuccinate(AOT),sodium sulfate and sodium hydroxide or hydrochloric acid were studied.The dust-removing and resistance-diminishing mechanism of complexation was analysed theoretically.The experiment about self-swash dust remover using water,AOT solution and complexation solution were conducted respectively.The result shows that the self-swash dust catcher using complexation solution not only enhances the efficiency of removing dust,especially respirable dust,but also reduces the resistance and energy consumption.The self-swash dust remover using complexation solution is much more rational and economical than using water at the same dust-removing efficiency and air volume.
