The kitchen is an important place in the family now, and the kitchen smoke exhaust pipe is now used as the passage to remove the kitchen smoke, so the daily maintenance is very important. Now let's learn how to maintain the smoke exhaust pipe in the daily use process with Dalong.

在對油煙管道進行清洗時，煙罩和灶臺的清洗也是不可缺少的，在清洗油煙管道前我們應對煙罩表面、排風口、煙罩內的燈罩、排煙口、電機、灶臺都要進行清潔，同時清潔的是排煙口和煙罩相連處與煙罩同步平行的排煙道。對這些部位的清潔不僅可以使煙道管道在清洗后更好的發揮它的作用，同時也使廚房的整個房間更加的干凈整潔。

When cleaning the oil smoke pipe, the cleaning of the hood and the stove is also indispensable. Before cleaning the oil smoke pipe, we should clean the surface of the hood, the air outlet, the lampshade, the smoke outlet, the motor, and the stove inside the hood. At the same time, the focus of cleaning is the smoke exhaust duct that is synchronous and parallel with the hood at the connection between the smoke outlet and the hood. The cleaning of these parts can not only make the flue pipe play its role better after cleaning, but also make the whole kitchen more clean and tidy.

排煙系統排煙罩的清洗需要使用化油劑將煙道內大量的油污鏟除，再用高壓清洗機噴射化油劑然后用清水沖洗干凈，長時間的使用，風機上的扇葉會形成很厚重的油污，也會影響風機的排風效果，清潔時先要將風機拆下來，清洗內部葉輪和內壁和表面。洗好后組裝前，建議給風機內添加潤滑油，這樣使得風機更加靈活。油煙凈化器也會因廚房通風排煙系統的通風效果而影響，長時間使用后，內部的極板和過濾網上都有大量的油污，凈化效果變差。清洗時建議先用清洗劑浸泡清洗。

For the cleaning of the smoke exhaust hood of the smoke exhaust system, a large amount of oil dirt in the flue shall be removed by using an oil reducing agent, and then sprayed with an oil reducing agent by a high-pressure washer, and then washed with clean water. After a long time of use, the fan blades on the fan will form very thick oil dirt, which will also affect the air exhaust effect of the fan. Before cleaning, the fan shall be removed, and the internal impeller, inner wall and surface shall be cleaned. After washing and before assembly, it is recommended to add lubricating oil to the fan to make it more flexible. The oil fume purifier will also be affected by the ventilation effect of the kitchen ventilation and smoke exhaust system. After a long time of use, there will be a lot of oil contamination on the internal electrode plate and filter screen, and the purification effect will become worse. It is recommended to soak and clean with detergent first.

我們都知道排煙系統都跟電路有關聯，在清洗的過程中容易進水，影響后期使用時線路的燒毀等，建議在和負責清洗的相關人員要說清楚這一點，能拆洗的就盡量選擇拆洗。油煙系統除了長時間進行一次大型的清洗，平時也要注意多做保養，如有些清洗公司在保養管道時，形成的保護膜也可以讓油漬不容易留下管道內。

We all know that the smoke exhaust system is related to the circuit. It is easy to get water in the process of cleaning, which affects the burning of the circuit in later use. It is recommended that the relevant personnel in charge of cleaning should be clear about this, and those who can be removed should be removed as much as possible. In addition to large-scale cleaning for a long time, the lampblack system should also be maintained frequently. For example, when some cleaning companies maintain the pipeline, the protective film formed can also prevent oil stains from leaving the pipeline.

廚房排煙管道標準：

Standard of kitchen smoke exhaust pipe:

1、廚房排煙管道的水平段不宜太長，通常水平距離不應超過15m，并且要有2%以上的坡度，水平末端設活接頭，以方便清理油垢。

1. The horizontal section of the kitchen smoke exhaust pipe should not be too long, usually the horizontal distance should not exceed 15m, and should have a slope of more than 2%. The horizontal end should be equipped with a movable joint to facilitate the cleaning of oil dirt.

2、廚房排煙管道的排風速度按規范不得低于10m/s，以防風速過低使油附著于煙道上，接排風罩的支管應設風量調節閥。

2. The exhaust speed of the kitchen smoke exhaust pipe shall not be less than 10m/s according to the specification to prevent oil from adhering to the flue due to low wind speed. The branch pipe connected to the exhaust hood shall be equipped with an air volume regulating valve.

3、廚房排煙系統的主排煙管道通風面積不能太小，風速不能太大。依照工程經驗，排煙主管道內風速不能超過15m/s。否則在運行一個時期以后（如一年以后）很容易造成排煙系統不通暢。

3. The ventilation area of the main smoke exhaust pipe of the kitchen smoke exhaust system shall not be too small, and the wind speed shall not be too large. According to the engineering experience, the wind speed in the main smoke exhaust pipe shall not exceed 15m/s. Otherwise, after a period of operation (such as one year), it is easy to cause the smoke exhaust system to be blocked.

排煙管道結構有什么要求

What are the requirements for smoke exhaust pipe structure

①排煙風道外外表與木質等可燃構件的距離不應小于15㎝,或在排煙道外外表包厚度不小于10㎝的保溫資料進行隔熱。

① The distance between the external surface of smoke exhaust duct and combustible components such as wood shall not be less than 15cm, or the external surface of smoke exhaust duct shall be insulated with insulation materials with a thickness of not less than 10cm.

②排煙風道穿過擋煙墻時，風道與擋煙隔墻之間的空地，應用水泥砂漿等不燃資料緊密填塞。

② When the smoke exhaust duct passes through the smoke retaining wall, the space between the duct and the smoke retaining partition wall shall be tightly filled with non combustible materials such as cement mortar.
