汇聚型空气幕集尘除尘系统的实验研究

为了解决稀土电解炉含氟烟尘浓度严重超标的问题，提出了一种汇聚型空气幕集尘除尘系统治理方案。通过实验测试的方法，研究了汇聚型空气幕装置的安装角与汇聚度及风机风量与空气幕汇聚度之间的关系，得到汇聚型空气幕装置的最佳工艺参数，为汇聚型空气幕的设计与制作提供了参考依据。通过对汇聚型空气幕集尘除尘系统风流流场的分析及实验条件的模拟，直观地获得了此系统风流流场的特征，同时进一步验证了汇聚型空气幕对污染气体隔离控制的可行性。

The Experimental Study of Dust Collecting and Removal System with Convergent Air Curtain

To solve the problem of excessive fluorine dust concentration of the rare earth electrolytic furnace, proposes a management scheme of convergent air curtain dust removal system. Through experiments, studies the relationship between the installing angle of convergent air curtain device and the convergence degree and the relationship of the fan air volume and the air curtain convergence degree, gets optimum technological parameters for convergent air curtain device, and provides the basis for production design. By means of analysis and experimental condition simulation on the airflow field of the convergent air curtain dust removal system, obtains the airflow characteristics of the system, thus further verifies the feasibility of the isolation control of polluted airs for the convergent air curtain.
