不同種類的am8亚美登录下载的工作原理:


The working principle of different kinds of oil fume purifiers:


1.催化劑燃燒法


1. Catalyst combustion method


燃燒凈化法的原理是利用高溫燃燒所產生的熱量進行氧化反應,把油煙廢氣中的污染物質轉化為CO2和H2O等物質,從而達到凈化目的。在燃燒過程中,讓油煙廢氣通過自凈化催化劑,催化劑的催化反應有利于污染物的轉化。一般采用陶瓷或金屬蜂窩進行載體進行氧化催化。這類亚美娱乐am8官方网站設備只適用油煙濃度很低的場合,如食物生吃或制作半成品。


The principle of combustion purification method is to use the heat generated by high temperature combustion to carry out oxidation reaction, and convert the pollutants in the exhaust gas of oil fume into such substances as CO2 and H2O, so as to achieve the purpose of purification. In the combustion process, the fume exhaust gas is allowed to pass through the self-purification catalyst, and the catalytic reaction of the catalyst is conducive to the conversion of pollutants. In general, ceramic or metal honeycomb carriers are used for oxidation catalysis. This kind of fume purification equipment is only suitable for low fume concentration occasions, such as raw food or semi-finished products.


2.活性炭吸附法

2. Activated Carbon Adsorption Method


用粒狀活性炭或活性炭纖維氈吸附油煙中的污染物粒子。這種設備的特點與過濾凈化設備相似,但去除油煙異味分子的效果較好。


Adsorption of pollutant particles in soot by granular activated carbon or activated carbon fiber felt. The characteristics of this equipment are similar to those of filtration and purification equipment, but the effect of removing odor molecules from oil fume is better.


3.靜電處理法


3. Electrostatic treatment


電場在外加高壓的作用下,負極的金屬絲表面或附近放出電子迅速向正極運動,與氣體分子碰撞并離子化。油煙廢氣通過這個高壓電場時,油煙粒子在極短的時間內因碰撞俘獲氣體離子而導致荷電,受電場力作用向正極集塵板運動,從而達到分離效果。這種設備的投資少、占地小、無二次污染、運行費用低。由于易于捕捉粒徑較小的粉塵,凈化效率高,可達85~95%。它的凈化機理與氣體方法的區別在于:分離力是靜電力,直接作用在粒子上,而不是作用在氣流上,因此具有能耗低,阻力小的特點。


Under the action of applied high voltage, electrons emitted from the wire surface or near the negative electrode move rapidly to the positive electrode, collide with gas molecules and ionize. When the fume exhaust gas passes through the high voltage electric field, the particles of the fume are charged by colliding and capturing gas ions in a very short time, and move towards the positive dust collector plate under the action of electric field force, thus achieving the separation effect. This kind of equipment has the advantages of less investment, less land occupation, no secondary pollution and low operation cost. Because it is easy to capture the dust with smaller particle size, the purification efficiency is high, up to 85-95%. The difference between its purification mechanism and gas method is that the separation force is electrostatic force, which acts directly on particles rather than on airflow, so it has the characteristics of low energy consumption and low resistance.
