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 transion 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.
主要缺点:活性炭成本较高。
Main shortcomings: high cost of activated carbon.
4、织物过滤法
4. Fabric filtration
油烟废气首先经过一定数目的金属格栅,大颗粒污染物被阻截;然后经过纤维垫等滤料后,颗粒物由于被扩散、截留而被脱除。通常选用的滤料材料为吸油性能高的高分子复合材料。这种设备投资少、运行费用低、无二次污染、维修管理方便;但阻力大、占地大、需要经常更换滤料的缺点。净化效率一般在80~92%。
Fumes are first passed through a certain number of metal gratings, and large particles are intercepted; then after the filter material such as fiber mats, the particles are removed because they are diffused and intercepted. The commonly used filter material is high polymer composite material with high oil absorption. The equipment has the advantages of less investment, low running cost, no two pollution, and convenient maintenance and management. However, it has the disadvantages of large resistance, large land occupation and frequent replacement of filter material. The efficiency of purification is generally in 80~92%.
缺点:由于滤料阻力很大,如玻璃纤维滤料的净化器压降可达1500Pa,且滤料需经常更换,使过滤法净化设备的应用受到局限。
Shortcomings: because of the high resistance of filter material, such as the pressure drop of the purifier of glass fiber filter material can reach 1500Pa, and the filter material should be replaced regularly, so the application of filter cleaning equipment is limited.
5、湿式处理法
5. Wet treatment
采用水或其他洗涤剂,以喷头喷洒的方式形成水膜,水雾来吸收油烟。油烟粒子与喷嘴喷出的水雾、水膜相接触,经过相互的惯性碰撞、滞留、细微颗粒的扩散和相互凝聚等作用,随水滴流下,从而使油烟离子从气流中分离出来。这种设备结构简单、投资少、占地小、运行费用低、维修管理方便。
Water or other detergents are used to form water film by sprinkler sprinkler, and mist is used to absorb soot. The oil fume particles are exposed to water mist and water film sprayed by the nozzle. Through the interaction of inertial collisions, stagnation, the diffusion of fine particles and the condensation of each other, the fume ions are separated from the air flow with the flow of water droplets. The device has the advantages of simple structure, less investment, small land occupation, low running cost and convenient maintenance and management.
