Introduction to common oil fume purifier equipment:

1.活性炭吸附油煙凈化設備

1. Activated carbon adsorption fume purification equipment

這種油煙凈化器的原理比較簡單，就是簡單的用活性炭吸附油煙顆粒。該原理不僅適用于油煙廢氣的凈化，還適用于煙霧空氣、PM2.5、工業(yè)廢氣等的凈化設備，具有很高的通用性。

The principle of this oil fume purifier is relatively simple, that is, it simply uses activated carbon to adsorb oil fume particles. The principle is applicable not only to the purification of oil fume and waste gas, but also to smoke air and PM2 5. Purification equipment for industrial waste gas has high universality.

雖然凈化能力強，但只能達到油煙凈化率的90%，廣泛應用于去除油煙異味的場合。

Although the purification capacity is strong, it can only reach 90% of the oil fume purification rate. It is widely used to remove the peculiar smell of oil fume.

缺點：活性炭昂貴，需要定期更換。Disadvantages: activated carbon is expensive and needs to be replaced regularly.

2.紫外光解油煙凈化設備

2. Ultraviolet photolysis oil fume purification equipment

事實上，紫外光實際上是紫外光。這種設備利用截面為C的紫外光將油煙分子分解為CO2(二氧化碳)、H2O(水蒸氣)和O3(臭氧)，并通過臭氧進一步氧化其他氣味分子。這種設備的原理有點像燃燒催化技術，但其覆蓋面更廣，凈化效率更高，可達90%。

In fact, ultraviolet light is actually ultraviolet light. This device uses ultraviolet light with cross section C to decompose oil fume molecules into CO2 (carbon dioxide), H2O (water vapor) and O3 (ozone), and further oxidizes other odor molecules through ozone. The principle of this equipment is a bit like combustion catalytic technology, but it has wider coverage and higher purification efficiency, up to 90%.

缺點：這種設備有一個很大的缺點，那就是紫外線對人體有很大的傷害，所以這種設備一般安裝在遠離廚房的通風管道中，并且保證通風管道不會被損壞，這樣紫外線就會漏出。

Disadvantages: this kind of equipment has a big disadvantage, that is, ultraviolet radiation does great harm to human body, so this kind of equipment is generally installed in the ventilation pipe far away from the kitchen, and ensure that the ventilation pipe will not be damaged, so that ultraviolet radiation will leak out.

3.靜電油煙凈化設備

3. Electrostatic fume purification equipment

這是目前市場上比較流行的油煙凈化器。其工作原理是當油煙廢氣通過高壓靜電場時，油煙廢氣中的顆粒與電子接觸并帶電，然后被電場吸附。

This is a popular fume purifier in the market at present. Its working principle is that when the oil fume exhaust gas passes through the high-voltage electrostatic field, the particles in the oil fume exhaust gas contact with electrons and are charged, and then adsorbed by the electric field.

這種設備可以捕捉0.1微米以下的細小顆粒，凈化率高達90%-95%。是目前凈化效率比較高的油煙凈化器。

This device can capture fine particles below 0.1 micron, and the purification rate is as high as 90% - 95%. It is a fume purifier with high purification efficiency at present.

缺點：設備成本高，電場板吸附容量大，需要定期清洗，否則凈化效率會降低。

Disadvantages: the equipment cost is high, the adsorption capacity of the electric field plate is large, and it needs to be cleaned regularly, otherwise the purification efficiency will be reduced.

4.催化劑燃燒油煙凈化設備

4. Catalyst combustion fume purification equipment

原理很簡單，就是將油煙引入陶瓷或金屬蜂窩爐進行高溫燃燒，油煙分子被催化劑氧化催化，使油煙和一些污染物轉化為CO2(二氧化碳)和H20(水蒸氣)。

The principle is very simple, that is, the oil fume is introduced into the ceramic or metal honeycomb furnace for high-temperature combustion, and the oil fume molecules are oxidized and catalyzed by the catalyst to convert the oil fume and some pollutants into CO2 (carbon dioxide) and H20 (water vapor).

缺點：由于催化燃燒技術不夠成熟，只能應用于低油煙濃度的環(huán)境，不能用于大型食堂。

Disadvantages: because the catalytic combustion technology is not mature enough, it can only be used in the environment with low oil fume concentration, not in large canteens.

5.油煙凈化設備的機械分離

5. Mechanical separation of oil fume purification equipment

采用離心力和慣性碰撞原理。當油箱中的油煙進入被凈化后，旋風裝置將快速旋轉，油煙顆粒將通過離心力從氣團中分離出來，撞擊擋板，然后隨著擋板向下流入集油盤。

The principle of centrifugal force and inertial collision is adopted. When the oil fume in the oil tank is purified, the cyclone device will rotate rapidly, and the oil fume particles will be separated from the air mass by centrifugal force, hit the baffle, and then flow down into the oil collecting pan with the baffle.

缺點：這種油煙凈化機的凈化率只有50%-60%，擋板容易損壞，需要定期維護。更適合凈化要求低的環(huán)境效果。

Disadvantages: the purification rate of this oil fume purifier is only 50% - 60%. The baffle is easy to be damaged and needs regular maintenance. It is more suitable for environmental effects with low purification requirements.

油煙凈化器

Fume purifier

6.織物過濾油煙凈化設備

6. Fabric filter oil fume purification equipment

事實上，這種油煙凈化器的原理與活性炭的吸附原理有些相似。它使用具有良好吸油性能的材料制成過濾層。當油煙分子通過過濾層時，油煙顆粒會被格柵阻擋。

In fact, the principle of this oil fume purifier is somewhat similar to the adsorption principle of activated carbon. It uses a material with good oil absorption performance to make a filter layer. When the oil fume molecules pass through the filter layer, the oil fume particles will be blocked by the grid.

這種裝置的油煙凈化率也可達80%以上，但不能阻止一些臭氣分子和廢氣，凈化對象有限。

The oil fume purification rate of this device can also reach more than 80%, but it can not prevent some odor molecules and waste gas, and the purification object is limited.

缺點：無法達到完全凈化，過濾層材料需要經常更換，設備占地面積大，不適合油煙凈化率要求高的環(huán)境。

Disadvantages: complete purification cannot be achieved, the filter layer materials need to be replaced frequently, and the equipment covers a large area, which is not suitable for the environment with high oil fume purification rate.

7.濕法處理油煙凈化設備

7. Oil fume purification equipment for wet treatment

顧名思義，它是與水有關的設備。是的，這種設備將水和清潔劑噴在一起，形成一個水罩或水霧空間。當油煙廢氣進入在凈化空間中時，油煙顆粒與水滴和水霧接觸，并結合到洗滌液中，然后隨著水流排出。

As the name suggests, it is a water related device. Yes, this equipment sprays water and detergent together to form a water cover or water mist space. When the oil fume exhaust gas enters the purification space, the oil fume particles contact with water droplets and water mist, combine into the washing solution, and then discharge with the water flow.

缺點：這種油煙凈化器有大量的油煙顆粒，一些微米級的廢氣分子仍然通過水膜進入的大氣，凈化率只有50-90%。排放的含油污水仍會對環(huán)境造成二次污染，性不強。

Disadvantages: this oil fume purifier has a large number of oil fume particles. Some micron waste gas molecules still enter the atmosphere through the water film, and the purification rate is only 50-90%. The discharged oily sewage will still cause secondary pollution to the environment, and the environmental protection is not strong.
