专注通风管道加工·排烟罩

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.

在对油烟管道进行清洗时，烟罩和灶台的清洗也是不可缺少的，在清洗油烟管道前我们应对烟罩表面、排风口、烟罩内的灯罩、排烟口、电机、灶台都要进行清洁，同时清洁的是排烟口和烟罩相连处与烟罩同步平行的排烟道。对这些部位的清洁不仅可以使烟道管道在清洗后更好的发挥它的作用，同时也使厨房的整个房间更加的干净整洁。

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.

排烟系统排烟罩的清洗需要使用化油剂将烟道内大量的油污铲除，再用高压清洗机喷射化油剂然后用清水冲洗干净，长时间的使用，风机上的扇叶会形成很厚重的油污，也会影响风机的排风效果，清洁时先要将风机拆下来，清洗内部叶轮和内壁和表面。洗好后组装前，建议给风机内添加润滑油，这样使得风机更加灵活。油烟净化器也会因厨房通风排烟系统的通风效果而影响，长时间使用后，内部的极板和过滤网上都有大量的油污，净化效果变差。清洗时建议先用清洗剂浸泡清洗。

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.

我们都知道排烟系统都跟电路有关联，在清洗的过程中容易进水，影响后期使用时线路的烧毁等，建议在和负责清洗的相关人员要说清楚这一点，能拆洗的就尽量选择拆洗。油烟系统除了长时间进行一次大型的清洗，平时也要注意多做保养，如有些清洗公司在保养管道时，形成的保护膜也可以让油渍不容易留下管道内。

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.

厨房排烟管道标准：

Standard of kitchen smoke exhaust pipe:

1、厨房排烟管道的水平段不宜太长，通常水平距离不应超过15m，并且要有2%以上的坡度，水平末端设活接头，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、厨房排烟管道的排风速度按规范不得低于10m/s，以防风速过低使油附着于烟道上，接排风罩的支管应设风量调节阀。

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、厨房排烟系统的主排烟管道通风面积不能太小，风速不能太大。依照工程经验，排烟主管道内风速不能超过15m/s。否则在运行一个时期以后（如一年以后）很容易造成排烟系统不通畅。

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.

排烟管道结构有什么要求

What are the requirements for smoke exhaust pipe structure

①排烟风道外外表与木质等可燃构件的距离不应小于15㎝,或在排烟道外外表包厚度不小于10㎝的保温资料进行隔热。

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排烟风道穿过挡烟墙时，风道与挡烟隔墙之间的空地，应用水泥砂浆等不燃资料紧密填塞。

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.
