Now the ventilation pipe can be seen everywhere in our daily life and industry, and its application is more and more widely. Maybe some people don't know what the ventilation pipe can help us. It doesn't matter. The ventilation pipe manufacturer will explain it to you slowly, and I believe we will understand it after listening to it.

每家的厨房里都有烟道，一起烟道也有主副之分，主烟道贯穿整个楼体，而副烟道是相对独立的。通常家里的油烟会先到副烟道里，然后再经过隔板上的孔进入主烟道，这样可保证每户的油烟是阻隔开来的。主烟道底层有一补风口。

Every kitchen has a flue, and there are main and auxiliary flue together. The main flue runs through the whole building, while the auxiliary flue is relatively independent. Usually, the lampblack in the house goes to the auxiliary flue first, and then goes into the main flue through the hole on the partition board, so as to ensure that the lampblack of each household is blocked. There is a make-up air outlet at the bottom of the main flue.

其原理是经过抽油烟机将烟气推入次烟道中，用抽油烟机推动力和油烟温度上浮力使油烟上升一段距离后再进入主烟道排出屋面,外加不锈钢烟道装饰板，烟道口可改入吊顶内。

The principle is that the flue gas is pushed into the secondary flue by the range hood, and then the flue gas rises for a certain distance by the driving force of the range hood and the buoyancy of the temperature of the flue gas, and then enters the main flue to discharge the roof, and the stainless steel flue decorative plate is added, and the flue port can be changed into the ceiling.

由于厨房地点建筑物的格局以及厨房在建筑物中位置不一样，有条件的厨房应由建筑物的会集空调体系进行有序送风。但目前所遇到的大多数情况是建筑物没有设置厨房的送风体系。

Due to the different layout of the building and the different position of the kitchen in the building, the conditional kitchen should be orderly supplied by the centralized air conditioning system of the building. But at present, most of the situation is that there is no kitchen air supply system in the building.

许多带餐厅、厨房等的建筑物，仅规划了会集采暖体系而无会集空调体系。当厨房处于工作状况时，排风体系投入运转，厨房内处于负压状况，新风来历包含室外新风浸透和餐厅的空气很多补入厨房。

Many buildings with restaurants, kitchens and so on are only planned with centralized heating system but no centralized air conditioning system. When the kitchen is in the working condition, the exhaust system is put into operation, and the kitchen is in the negative pressure condition. The origin of fresh air includes outdoor fresh air infiltration and a lot of restaurant air into the kitchen.

以上就是通风管道在厨房的应用，正因为有了通风管道，厨房才少了油烟，通风管道给我们的生活带来了很多的便利。

The above is the application of ventilation pipe in the kitchen. Because of the ventilation pipe, the kitchen has less oil smoke, and the ventilation pipe has brought a lot of convenience to our life.
