每個酒店都會配備一個排煙罩，因為排煙罩的排煙能力很強，而且使用時間長了會有難聞的氣味，怎么辦呢？讓我們談談如何處理它。

Each hotel will be equipped with a smoke exhaust hood, because the smoke exhaust hood has a strong smoke exhaust capacity, and it will smell bad after a long time of use. What should we do? Let's talk about how to deal with it.

煙道位置可安裝止回閥。當油煙通過止回閥時，止回閥可使油煙直接向動，避免向下流動。一個的止回閥不僅可以保護排煙罩，還可以有效防止煙道中的油煙倒流到排煙罩和管道內部，造成室內異味現象。

High quality check valve can be installed at the flue. When the oil fume passes through the check valve, the check valve can make the oil fume flow upward directly to avoid downward flow. A high-quality check valve can not only protect the exhaust hood, but also effectively prevent the oil smoke in the flue from flowing back to the exhaust hood and the pipe, causing indoor odor.

也可以在煙道出口直接安裝氣密閥。在密閉閥和罩閥共同作用下，一般不是很嚴重的油煙不能倒回管道和罩。

The gas tight valve can also be directly installed at the flue outlet. Under the joint action of the sealing valve and the cover valve, generally, the oil fume that is not very serious cannot be returned to the pipe and cover.

如果排煙罩有異味是由于排煙罩的破裂和連接不良造成的，可以更換新的排煙罩的抽油管，或者重新連接排煙罩。

If the peculiar smell of the exhaust hood is caused by the rupture and poor connection of the exhaust hood, the oil extraction pipe of the new exhaust hood can be replaced or the exhaust hood can be reconnected.

如果排煙罩有異味是由于排煙管與公煙道的連接處密封不好造成的，可以用玻璃膠或透明膠將縫隙密封嚴密。

If the peculiar smell of the smoke exhaust hood is caused by the poor sealing of the joint between the smoke exhaust pipe and the public flue, the gap can be sealed tightly with glass glue or transparent glue.

為了更好的擴大房子的使用面積，有的業主將廚房灶臺設計在陽臺位置，排煙管直接排入屋內。這可以是放置房子的話和倒流的好方法，但是會污染環境，并不是所有的社區都允許這種改造。以后如果強行改，就麻煩多了。

In order to better expand the use area of the house, some owners design the kitchen stove at the balcony, and the smoke exhaust pipe is directly discharged into the house. This can be a good way to place houses and reverse the flow, but it will pollute the environment. Not all communities allow this kind of transformation. In the future, if it is forced to change, it will be much more troublesome.

裝修前先選購排煙罩、燃氣灶、熱水器，確定開孔的位置和大小。避免貼磚后鉆孔造成的不便。

Before decoration, smoke exhaust hood, gas stove and water heater shall be purchased to determine the location and size of the opening. Avoid inconvenience caused by drilling after tiling.

濟南排煙罩的煙管與煙道的佳距離為1.5m，超過3m會大大影響排煙效果。排煙管的長度需要加上從排煙罩噴口到煙管水平方向的長度

The best distance between the smoke pipe and flue of Jinan smoke exhaust hood is 1.5m, and more than 3m will greatly affect the smoke exhaust effect. The length of the smoke exhaust pipe needs to add the length from the nozzle of the smoke exhaust hood to the horizontal direction of the smoke pipe.

在您自己的排煙罩的煙道口安裝一個止回閥。排煙罩工作時會打開，不工作時會自動關閉，這樣公共煙道的油煙就不會進入您的廚房。但安裝止回閥后，應定期清洗，否則止回閥打開而失去作用，煙道止回閥應每兩年左右更換一次。

Install a check valve at the flue outlet of your own exhaust hood. The smoke exhaust hood will open when it works and close automatically when it does not work, so that the oil smoke from the public flue will not enter your kitchen. However, after the check valve is installed, it should be cleaned regularly, otherwise the check valve will open and lose its function. The flue check valve should be replaced every two years or so.
