  • 油烟净化器静电处理法的优点
  • 本站编辑:杭州东润科技实业有限公司发布日期:2019-06-08 09:15 浏览次数:
电场在外加高压的作用下,负极的金属丝表面或附近放出电子迅速向正极运动,与气体分子碰撞并离子化。油烟废气通过这个高压电场时,油烟粒子在极短的时间内因碰撞俘获气体离子而导致荷电,受电场力作用向正极集尘板运动,从而达到分离效果。这种设备的投资少、占地小、无二次污染、运行费用低。由于易于捕捉粒径较小的粉尘,净化效率高,可达85~95%。它的净化机理与气体方法的区别在于:分离力是静电力,直接作用在粒子上,而不是作用在气流上,因此具有能耗低,阻力小的特点。
静电过滤器:含有粉尘颗粒的气体,在接有高压直流电源的阴极线(又称电晕极)和接地的阳极板之间所形成的高压电场通过时,由于阴极发生电晕放电、气体被电离,此时,带负电的气体离子,在电场力的作用下,向阳板运动,在运动中与粉尘颗粒相碰,则使尘粒荷以负电,荷电后的尘粒在电场力的作用下,亦向阳极运动,到达阳极后,放出所带的电子,尘粒则沉积于阳极板上,而得到净化的气体排出防尘器外。
高压静电设备的技术优点:
1.处理风量大,压损小。可以在高湿情况下运行。
2.一次通过去除率可以满足净化要求。
3.有效去除的粒子直径范围大。

Under the action of an applied high pressure, the negative wire surface or nearby emits electrons that quickly move to the positive pole, collides with gas molecules and ionizes. When the soot exhaust gas passes through this high-pressure electric field, the soot particles are charged by collision to capture gas ions in a very short period of time, and the electric field force moves toward the positive collector dust plate to achieve the separation effect. The equipment has low investment, small footprint, no secondary contamination and low operating costs. Due to the easy capture of smaller dust particles, high purification efficiency, up to 85 ~ 95 %. The difference between its purification mechanism and the gas method is that the separation force is electrostatic, acting directly on the particles rather than on the air flow, so it has the characteristics of low energy consumption and low resistance.
Electrostatic filter: A gas containing dust particles. When a high-pressure electric field formed between a cathode line(also known as a corona) connected to a high voltage DC power supply and a grounded anode plate passes through, a corona discharge occurs at the cathode and the gas is ionized. At this time, The negatively charged gas ions, under the action of the electric field force, move toward the sun plate, and when they collide with the dust particles during the movement, the dust particles are negatively charged, and the charged dust particles are under the action of the electric field force. It also moves toward the anode and arrives at the anode. The electrons are released, and the dust particles are deposited on the anode plate, and the purified gas is discharged out of the dust filter.
Technical advantages of high voltage electrostatic equipment:
1. Treatment of large wind, small pressure loss. Can run under high humidity conditions.
2. The removal rate can meet the purification requirements at one time.
3. The effective removal of particles has a large range of diameters.
