Jinan kitchen smoke exhaust equipment is one of the indispensable equipment in our family and catering industry. With our country vigorously advocating environmental protection, many restaurants are actively installing oil fume purification equipment, which can purify oil fume and harmful gases in the kitchen. Let's take a look at it.

济南厨房排烟设备——油烟净化器的工作原理：可使油烟由风机吸入油烟净化设备，其中部分较大的油雾滴、油污颗粒在均流板上由于机械碰撞、阻留而被捕集。

Working principle of Jinan kitchen smoke exhaust equipment - oil fume purifier: the oil fume can be sucked into the oil fume purification equipment by the fan, and some large oil mist droplets and oil particles are trapped on the flow equalizing plate due to mechanical collision and retention.

当气流进入处于高压静电场时，在高压电场的作用下，油烟气体电离，油雾带电，大部分被降解和碳化;在电场力和电场吸收的气流的作用下，少量微小的油颗粒向电场的正负极板移动，聚集在极板上，在自身重力的作用下向下流到集油盘，通过排油通道排出，剩余的微米级油雾被电场降解为二氧化碳和水，然后排出干净的空气;同时，在高压发生器的作用下，电场中的空气中产生臭氧，烟气中的大部分臭气被去除。

When the air flow enters the high-voltage electrostatic field, under the action of the high-voltage electric field, the oil fume gas ionizes, the oil mist is charged, and most of it is degraded and carbonized; Under the action of the electric field force and the air flow absorbed by the electric field, a small amount of tiny oil particles move to the positive and negative plates of the electric field, gather on the plates, flow down to the oil collecting pan under the action of their own gravity, and discharge through the oil discharge channel. The remaining micron oil mist is degraded into carbon dioxide and water by the electric field, and then discharge clean air; At the same time, under the action of the high voltage generator, ozone is generated in the air in the electric field, and most of the odor in the flue gas is removed.

为了提高油烟净化器的净化效率，需要考虑净化器的原理、材料和风机类型。

In order to improve the purification efficiency of oil fume purifier, the principle, material and fan type of purifier need to be considered.

1、油烟净化设备的原理：

1. Principle of fume purification equipment:

油烟净化设备采用过滤分离的原理，实际上是通过过滤、冷却、吸附等技术去除油烟。

The oil fume purification equipment adopts the principle of filtration and separation. In fact, it removes oil fume through filtration, cooling, adsorption and other technologies.

2.油烟净化设备的材料：

2. Materials of oil fume purification equipment:

油烟净化设备采用耐高温、耐腐蚀、冷却性能好的材料，提高净化效率。

The oil fume purification equipment adopts materials with high temperature resistance, corrosion resistance and good cooling performance to improve the purification efficiency.

3.风机型油烟净化设备：

3. Fan type oil fume purification equipment:

不同的油烟净化器风机出口有不同的尺寸和风量，净化效率也不同。此外，后端净化风速快，净化效率低;但是，前端净化风速慢，净化效率高。

The fan outlet of different oil fume purifiers has different size and air volume, and the purification efficiency is also different. In addition, the back-end purification wind speed is fast and the purification efficiency is low; However, the front-end purification wind speed is slow and the purification efficiency is high.
