With the progress and development of science and technology, major scientific research companies have also made good achievements in the innovation of oil fume purifier. Nowadays, the brand and shape of lampblack purifier are very wide on the market, but the general purification principle is very few.

1、静电式

1. Electrostatic type

静电式油烟净化器利用阴极在高压电场中释放的电子和电子与空气分子碰撞产生的负离子捕获油烟粒子，使油烟粒子带电。利用电场的作用，将带电的油烟颗粒吸附在阳极上，达到去除油烟的目的。

Electrostatic soot purifier traps soot particles by using negative ions produced by electrons and electrons colliding with air molecules released by cathode in high voltage electric field, which makes soot particles charged. Using the electric field, the charged soot particles are adsorbed on the anode to remove the soot.

根据静电油烟净化设备中电场极板的不同形状，可分为蜂窝状极板和线状极板。

According to the different shapes of the electric field plate in the electrostatic oil fume purification equipment, it can be divided into honeycomb plate and linear plate.

光解公式

Photolysis Formula

用特殊波长的紫外光照射油烟分子，净化油烟分子。

The lampblack molecule is purified by irradiating lampblack molecule with special wavelength ultraviolet light.

光解、氧化油烟气净化技术是使用紫外线- c波段光改变油分子链,与此同时,这种紫外线和空气中的氧气反应后产生臭氧,臭氧分子油冷燃烧生成水和臭氧后,同时在烟道气味也消除了。

Photolysis and oxidation of oil fume purification technology is the use of ultraviolet-C band light to change the oil molecular chain. At the same time, this ultraviolet radiation reacts with oxygen in the air to produce ozone. Ozone molecule oil burns to produce water and ozone, while the odor of the flue gas is eliminated.

第三,湿

Third, wetness

湿式主要是采用喷水(水幕)方式过滤烟气中的油雾，称为湿式。该方法对大油雾颗粒去除率高，对小颗粒去除率低。由于油烟雾滴的疏水性，需要在该装置的洗涤水中添加各种表面活性剂和乳化剂，以提高油水的混合性能。它能去除水中溶解的一些有害气体和气味，同时实现火灾烟气和油烟的处理。

Wet type mainly uses water spraying (water curtain) to filter oil mist in flue gas, which is called wet type. The method has high removal rate of large oil mist particles and low removal rate of small particles. Because of the hydrophobicity of oil smoke droplets, various surfactants and emulsifiers need to be added to the washing water of the device to improve the mixing performance of oil and water. It can remove some harmful gases and odors dissolved in water, and realize the treatment of fire smoke and lampblack at the same time.

目前除油烟外效果好的产品是湿式油烟净化器。一体式油烟净化机，采用液体泡沫清洗原理，能自动清洗机体内的低空直列油烟。没有复杂的管道设施，安装简单。

At present, the wet oil fume purifier is the best product besides oil fume. The integrated lampblack purifying machine adopts the principle of liquid foam cleaning, and can automatically clean low altitude straight row lampblack in the machine body. No complex pipeline facilities, simple installation.
