空气净化静电吸附装置的研制及应用

Development and application of electrostatic adsorption device for air purification

海洋石油平台透平机组进气系统的空气净化均采用物理过滤方法,空气中以溶胶状存在的盐雾不可避免地会造成滤芯寿命大幅度降低。根据静电吸附原理,采用电晕线和集电极管束结构、运用全生命周期经济效果分析方法设计、研制的静电吸附装置能够提高透平进气质量,除盐雾效率可达94%(质量分数),从而提升滤芯使用寿命。简要介绍了静电吸附原理,较为详细地论述了静电除盐雾试验装置的研制及除盐雾效果、透平进气系统静电吸附实用装置的研制,最后阐明了采用全生命周期经济效果分析方法确定吸附实用装置结构参数的过程及该装置的使用效果。

Air purification of gas inlet system of turbine unit on offshore platform applies physical filtering method.Salt mist aerosol in air can inevitably decrease service life of filter element.Based on the electrostatic adsorption principle and adopting corona wire and collector tube bundle structure,then applying lifecycle economic effect analysis method to design and develop an electrostatic adsorption device can raise turbine unit gas inlet quality,the salt mist eliminating efficiency reaches94%so as to prolong lifecycle of the filter element.This article illustrates the development of the electrostatic adsorption experimental device and its salt mist eliminating effect,the development of the applied turbine unit electrostatic adsorption device,the structural parameters determination with lifecycle economic effect analysis method,and the application effect of the device.
