2. The working principle of
靠高壓電暈放電使得粉塵荷電，荷電后的粉塵在電場(chǎng)力的作用下到達(dá)集塵板，但是在對(duì)集塵板上捕集到的粉塵清灰方式上有較大的區(qū)別，它采用沖刷液沖洗電極，在極板上形成連續(xù)的液膜，使粉塵隨著沖刷液的流動(dòng)而清除。煙氣中的灰塵顆粒通過(guò)高壓電磁場(chǎng)時(shí)與電 極間的正負(fù)離子與電子碰撞而產(chǎn)生的荷電，帶上電子和離子的塵粒在電場(chǎng)力的作用下向異性電極運(yùn)動(dòng)并積附在異性電極上，通過(guò)振打等方式使電極上的灰塵落入收集 灰斗中，使它通過(guò)電除塵器的煙氣得到凈化，從而達(dá)到除塵效果。
By high voltage corona discharge makes the dust charged and dust charged after arrive in dust collecting plate under the action of electric field force, but on the dust collection plate capture to the way of dust removal by a larger difference between the two, it USES flush fluid flush electrodes, form continuous liquid film on the plate, make the dust as the flushing fluid flow and clear. Dust particles in flue gas by high voltage electrical interelectrode electromagnetic field with the positive and negative ions and electrons collide and charged, with electrons and ions of dust particles under the action of electric field force, anisotropic electrode movement and attached to the opposite sex electrode, through shaking of the electrode on the dust falls to the collected ash hopper, make it through electric precipitator flue gas purification, so as to achieve the dust removal effect.
