目前市场上的油烟净化处理技术方法有机械分离法、催化剂燃烧法、活性炭吸附法、织物过滤法、湿式处理法及静电处理法。

At present, there are mechanical separation, catalyst combustion, activated carbon adsorption, fabric filtration, wet treatment and electrostatic treatment.

1、机械分离法

1. Mechanical separation

利用惯性碰撞原理或旋风分离原理对油烟进行分离。

The oil fume was separated by the principle of inertial collision or the principle of cyclone separation.

缺点：挡板滤网容易破裂，废弃直接排放；需要定期保养和维护；安装的垂直角度要小于15°；净化效率不高，只适用于预处理或净化效率要求较低的场合。

Shortcomings: the baffle screen is easy to break down and discarded directly; it needs regular maintenance and maintenance; the vertical angle of the installation is less than 15 degrees; the purification efficiency is not high, it is only suitable for the situation where the efficiency of pretreatment or purification is low.

2、催化剂燃烧法

2, catalyst combustion method

燃烧净化法的原理是利用高温燃烧所产生的热量进行氧化反应，把油烟废气中的污染物质转化为CO2和H2O等物质，从而达到净化目的。在燃烧过程中，让油烟废气通过自净化催化剂，催化剂的催化反应有利于污染物的转化。一般采用陶瓷或金属蜂窝进行载体进行氧化催化。这类油烟净化设备只适用油烟浓度很低的场合，如食物生吃或制作半成品。

The principle of the combustion purification method is to use the heat produced by the high temperature combustion to oxidize, and convert the pollutants in the fume waste gas into CO2 and H2O, so as to achieve the purify purpose. During the combustion process, the fume exhaust gas passes through the self purification catalyst, and the catalytic reaction of the catalyst is favorable for the transformation of pollutants. Generally, ceramic or metal honeycomb is used as carrier for oxidation catalysis. This kind of lampblack purification equipment is only suitable for occasions with low oil fume concentration, such as raw food or semi-finished products.

缺点：催化燃烧净化设备的开发还不十分成熟。

Disadvantages: the development of catalytic combustion purification equipment is not very mature.

3、活性炭吸附法

3. Activated carbon adsorption method

用粒状活性炭或活性炭纤维毡吸附油烟中的污染物粒子。这种设备的特点与过滤净化设备相似，但去除油烟异味分子的效果较好。

Granular activated carbon or activated carbon fiber felt is used to adsorb pollutants from lampblack. The equipment is similar to the filtration and purification equipment, but the effect of removing the odor molecules is good.
