關(guān)于廚房排煙管道設(shè)計(jì)和裝置不合理有哪些原因?下面由排煙管道的人員介紹一下：

What are the reasons for the unreasonable design and installation of kitchen smoke exhaust pipes? The following is an introduction by the professional staff of smoke exhaust pipes:

一、主排煙管道通風(fēng)面積不行

1. Ventilation area of main exhaust pipe is not good

依據(jù)工程經(jīng)驗(yàn)，排煙主管道內(nèi)風(fēng)速不能超過15m/s，否則在運(yùn)轉(zhuǎn)一個(gè)時(shí)期以后很簡(jiǎn)單形成排煙系統(tǒng)不曉暢。在油煙凈化器的運(yùn)轉(zhuǎn)實(shí)踐中，大部分案例都是因排煙管道通風(fēng)面積缺乏引起的不曉暢，管道內(nèi)氣體的流速都在15m/s以上。

According to engineering experience, the wind speed in the main smoke exhaust pipe should not exceed 15 m/s. Otherwise, after a period of operation, the smoke exhaust system can not be smoothly formed. In the operation practice of the oil fume purifier, most cases are caused by the lack of ventilation area of the exhaust pipe, and the flow rate of the gas in the pipe is above 15m/s.

二、管道截面積變小

II. Reduction of Pipeline Section Area

排煙管道因?yàn)橐┻^修建梁而使管道通風(fēng)截面積變小，截面上阻力增加，形成氣流不曉暢。

Because the smoke exhaust pipeline passes through the building beam, the ventilation cross-section area of the pipeline becomes smaller, the resistance on the cross-section increases, and the airflow is not clear.

三、排管道使用后積累物堆積

3. Accumulate accumulation after use of drainage pipeline

排煙管道在穿過修建梁或躲避其它設(shè)備管道時(shí)，排煙管道中的一段會(huì)低于整體排煙管道平面，在使用一段時(shí)間后，因?yàn)橛退旌衔飼?huì)積累在較低的那段排煙管道中，直接影響排煙曉暢。

When the smoke exhaust pipeline passes through the building beam or avoids other equipment pipelines, one section of the smoke exhaust pipeline will be lower than the overall level of the smoke exhaust pipeline. After a period of use, because the oil-water mixture will accumulate in the lower section of the smoke exhaust pipeline, which directly affects the smoothness of smoke exhaust.

四、低層排煙不順利

4. Smoke exhaust at low level is not smooth

不同樓層的廚房油煙通過同一主管道排出，離出口近的樓層廚房排煙效果較好，而較低樓層的廚房排煙不曉暢。

The kitchen fumes of different floors are discharged through the same main pipe. The kitchen fumes of the floors near the exit are better, while the kitchen fumes of the lower floors are not smoothly exhausted.

五、主張配備排煙風(fēng)機(jī)

Fifth, advocating the equipping of smoke exhaust fans

關(guān)于油煙較大的廚房，主張還配備一個(gè)排煙風(fēng)機(jī)。常用的排煙風(fēng)機(jī)有軸流風(fēng)機(jī)、風(fēng)機(jī)箱和離心風(fēng)機(jī)3種。

As for kitchens with bigger oil fumes, it is advocated that a smoke exhaust fan should also be equipped. The common smoke exhaust fans are axial fan, fan box and centrifugal fan.
