摘　　要：为提高泡沫降尘效果,搭建了泡沫除尘系统实验平台,深入分析了风压和气体流量对发泡倍数的影响。实验结果表明:风压对发泡倍数的影响很小;而气体流量与发泡倍数呈"抛物线"型的关系;在气压0.2 MPa、水压0.05 MPa、发泡剂体积分数0.5%、管路长10 m的条件下,达到最佳发泡倍数约为10～15倍,此时最佳气体流量为60～80 m3/h。该研究为泡沫降尘技术的应用提供了理论依据。Aimed at improving the foaming effect,this paper introduces an experimental platform designed for foam dust removal system and a deeper analysis of the wind pressure and gas flow on the influence of the foam multiple.The experimental results show that wind pressure has little effect on foam multiple,the gas flow rate and foam multiple presents ＂parabolic＂ type relationship,and the wind pressure of 0.2 MPa,water pressure of 0.05 MPa,the proportion of foam agent of 0.5%,and the pipeline length of 10 m,produce the best foaming effect of 10~15,with the resultant optimum gas flow of 60～80 m3/h.This experimental research provides a theoretical basis for the application of froth dedusting.
