宽间距电除尘器主要特点是节省材料;本体自重小;由于安装及运转等各种原因造成板间距的相对误差小;人体可进入板极之间,检修方便〔1～3,5～8〕。故此,近年来宽间距电除尘器作为一种特殊型电除尘器〔5〕得到迅速发展。 1956年G.Heinrich对英国的一台处理粉煤灰的电除尘器作了工业试验〔1〕,结果表明,尽管板间距比原来加宽一倍,集尘面积减少一半,而电除尘器的除尘效率几乎不变或略有提高.
The main feature of the wide-pitch electrostatic precipitator is that it saves materials; the body’s own weight is small; due to various reasons such as installation and operation, the relative error of the plate spacing is small; the human body can enter between the plate poles, and the inspection and maintenance are convenient [1～3,5～8] . Therefore, in recent years, a wide-range electrostatic precipitator has been rapidly developed as a special-type electrostatic precipitator [5]. In 1956 G. Heinrich conducted an industrial test of an electric dust collector for handling fly ash in the UK [1]. The results showed that although the spacing between plates was doubled, the dust collection area was reduced by half, and the electrostatic precipitator was Dust collection efficiency is almost unchanged or slightly increased.
