為了解決廚房的油煙問題，我們通常會專門設計一個煙道來排煙。現在每家每戶還配備了抽油煙機，本來是用來排煙的。但有人會發現的廚房排煙沒起作用，這要如何處理這種情況？為了防止這些問題，應注意以下幾點。
In order to solve the problem of oil smoke in the kitchen, we usually design a flue to smoke. Now every household is also equipped with a range hood, which was originally used to smoke. But some people will find that the kitchen smoke exhaust doesn't work. How to deal with this situation? In order to prevent these problems, we should pay attention to the following points.
每個廚房都有煙道，但你知道還有主煙道和副煙道嗎？主煙道貫穿整個建筑。輔助煙道相對獨立。用帶孔的擋板與主煙道隔開，上下兩側用地板密封。一般家里的油煙都會先到副煙道做緩沖，再通過隔板上的小孔進入主煙道，這樣可以保證每戶的油煙都被堵住，不會被熏制。
Every kitchen has flues, but do you know there are also main flues and auxiliary flues? The main flue runs through the whole building. The auxiliary flue is relatively independent. The baffle with holes is used to separate it from the main flue, and the upper and lower sides are sealed with floors. Generally, the lampblack in the home will be buffered in the auxiliary flue first, and then enter the main flue through the small hole on the partition, so as to ensure that the lampblack in each household is blocked and will not be smoked.
主副煙道必須同時存在。部分業主家中出現倒煙或雜煙現象，可能是裝修時把排煙管誤接在主煙道上，或者為了節省空間而拆除了輔助煙道。如果直接與主煙道相連，因為它的向上吸力很強，被比喻為“拔罐效應”。一旦氣壓相對較低，它可能會將其他房屋的煙霧壓到您自己的位置。輔助煙道緩沖效果好，不能拆除。
The main and auxiliary flue must exist at the same time. Some owners' homes have smoke pouring or Miscellaneous smoke, which may be due to the mistakenly connecting the smoke exhaust pipe to the main flue during decoration, or the removal of the auxiliary flue in order to save space. If it is directly connected with the main flue, it is compared to "cupping effect" because of its strong upward suction. Once the air pressure is relatively low, it may press the smoke of other houses to your own position. The auxiliary flue has good cushioning effect and cannot be removed.
如果輔助煙道已經拆除，或者要求防煙倒灌效果更好，建議使用煙道止回閥。一般情況下抽油煙機止回閥的作用不是很顯著，在煙道安裝止回閥可以保護抽油煙機，使煙道內的煙氣不會倒流到管道中，抽油煙機。但安裝止回閥后，應定期清洗，否則止回閥會打開而失去作用。煙道止回閥應每2年更換一次。
If the auxiliary flue has been removed, or it is required that the smoke backflow prevention effect is better, it is recommended to use the flue check valve. In general, the role of the check valve of the range hood is not very significant. Installing the check valve in the flue can protect the range hood, so that the flue gas in the flue will not flow back into the pipeline. However, after installing the check valve, it should be cleaned regularly, otherwise the check valve will open and lose its function. The flue check valve should be replaced every 2 years.
濟南廚房排煙廠家認為選擇抽油煙機的安裝位置非常重要。管子越短越好。有的業主為了美觀，將管道拉長了一些，這樣抽油煙機關閉后，管道內會積聚大量油煙無法排出，然后倒回室內。另外，為了不損壞原主副煙道，開口的開口方向不能隨意改變，必須在副煙道內打。但煙道的孔可以擴大，但要注意不要損壞二級煙道的擋板。
Jinan kitchen smoke exhaust manufacturers believe that it is very important to choose the installation position of the range hood. The shorter the pipe, the better. Some owners lengthen the pipe for the sake of beauty, so that after the lampblack smoking mechanism is closed, a large amount of lampblack will accumulate in the pipe and cannot be discharged, and then return to the room. In addition, in order not to damage the original main and auxiliary flue, the opening direction of the opening cannot be changed at will, and it must be punched in the auxiliary flue. However, the hole of the flue can be expanded, but care should be taken not to damage the baffle of the secondary flue.
Pay attention to the above points, and I believe that the problem of kitchen smoke exhaust can be well solved. After that, you need to remember that the kitchen decoration should not only be beautiful and generous, but also practical, practical and convenient.
