Application of Electrostatic Precipitators with Wider Electrode Spacing and Longer Discharge Spine Electrode

Technology with wider electrode spacing and longer discharge spine electrode in electrostatic precipitators is one of the achievements of the research projects in the 9th National Five Year Plan. It not only reduces the consumption of metallic materials, but also decreases working voltage range of the dust collectors to a relatively normal level. Consequently, this technology makes the insulation problems much easier than before, and saves more primary investment. Results from the field show that this equipment could not only effectively control the dust pollution in the workplace, but also could keep the working electric current and voltage stable, high dust collecting efficiency, low resistance and steady and reliable operation.
