分歧品種的油煙汙染器的任務道理:


The working principle of different kinds of oil fume purifiers:


1.催化劑熄滅法


1. Catalyst combustion method


熄滅汙染法的道理是應用低溫熄滅所發生的熱量停止氧化反響,把油煙廢氣中的凈化物資轉化爲CO2和H2O等物資,從而到達汙染目標。在熄滅過程當中,讓油煙廢氣經由過程自汙染催化劑,催化劑的催化反響有益于凈化物的轉化。普通采取陶瓷或金屬蜂窩停止載體停止氧化催化。這類油煙汙染設備只實用油煙濃度很低的場所,如食品生吃或制造半制品。


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凈化物粒子。這類設備的特色與過濾汙染設備類似,但去除油煙異味份子的後果較好。


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.靜電處置法


3. Electrostatic treatment


電場在外加高壓的感化下,負極的金屬絲外面或鄰近放出電子敏捷向正極活動,與氣體份子碰撞並離子化。油煙廢氣經由過程這個高壓電場時,油煙粒子在極短的時光內因碰撞俘獲氣體離子而招致荷電,受電場力感化向正極集塵板活動,從而到達分別後果。這類設備的投資少、占地小、無二次凈化、運轉費用低。因為易于捕獲粒徑較小的粉塵,汙染效力高,可達85~95%。它的汙染機理與氣體辦法的差別在于:分別力是靜電力,直接感化在粒子上,而不是感化在氣流上,是以具有能耗低,阻力小的特色。


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.
