How to deal with oil fume backward flow?

most Chinese dishes are stir-fried, so the kitchen fume is relatively large. Although the range hood is installed, problems such as oil fume backflow often occur, especially in summer when the temperature is high, if the gas stays in the flue and cannot be discharged, it will cause certain damage to the range hood. So how to deal with the problem of oil fume backflow? Let's take a look at the relevant knowledge immediately.

First, how to deal with the oil fume backflow

Installing a check valve in the air outlet area of the range hood can eliminate the problems of oil fume backflow and unsmooth smoke exhaust; Or we can transform the inlet of the hose of the range hood and change the air inlet to the position of the auxiliary flue, which not only slows down the rising speed of the lampblack, but also increases the resistance; Sometimes the doors and windows of the kitchen are closed too tightly, which leads to the air pressure in the kitchen being smaller than that in the flue. If someone else's cigarette oil is poured in, it can be solved by opening the doors and windows.

2. Why does the oil fume flow backwards

1. If the oil fume flows backwards in a high-rise building, it is very likely that the construction waste accidentally falls into the flue and is blocked in the early stage of decoration. If this happens to many households in the kitchen of the same building, contact the property as soon as possible to clean it up.

2. In order to decorate the kitchen beautifully, some families install the exhaust hole of the range hood on the ceiling. Generally speaking, the position of the flue hole reserved by the developer is downward. In order to install it on the ceiling, the flue hole originally designed by the developer is sealed, and a new opening is made at the upper end to move the flue opening up, which will lead to the effect that the auxiliary flue loses its stall. In addition, the exhaust pipe is placed in the public flue, which is prone to the situation of oil smoke backflow.

3. When there is something wrong with the flue check valve, grease will stick to the gas, or if the backflow valve and the flue taste are not well sealed, it will lead to oil smoke. It is suggested to try replacing a backflow valve again, or reseal it with glass glue.
