排煙管道的設(shè)計(jì)和安裝不合理，往往會(huì)造成廚房排煙不通暢，直接影響油煙凈化器的使用。對于餐飲業(yè)的廚房來說，排煙是否通暢直接關(guān)系到廚房能否正常工作，油煙凈化則只是廚房排煙系統(tǒng)中的一個(gè)凈化空氣的強(qiáng)制性功能。排煙系統(tǒng)和凈化器的合理匹配是保證油煙凈化器凈化效率的關(guān)鍵，同時(shí)也是油煙凈化器設(shè)計(jì)人員容易忽略的問題，如果排煙系統(tǒng)設(shè)計(jì)不合理而造成整個(gè)廚房排煙不暢，則將無法安裝油煙凈化器，即使安裝了油煙凈化器也無法正常工作。

The design and installation of the exhaust pipe is not reasonable, which often causes the unobstructed smoke in the kitchen, which directly affects the use of the fume purifier. For the kitchen of the catering industry, whether the smoke is smooth is directly related to whether the kitchen can work normally, and the lampblack purification is only a mandatory function of purifying the air in the kitchen exhaust system. The smoke purifier system and reasonable matching is the key to ensure the purification efficiency of oil fume purifier, and fume purifier designers often ignore the problem, if the exhaust system design is unreasonable and cause the entire kitchen exhaust is not smooth, it will not be installed fume purifier, even installed fume purifier does not work.

廚房的排風(fēng)機(jī)一般應(yīng)選用離心風(fēng)機(jī)，廚房的排風(fēng)管應(yīng)盡量避免過長的水平風(fēng)道。廚房的排風(fēng)管應(yīng)盡量避免過長的水平風(fēng)道。廚房的排風(fēng)豎井好與排煙道靠在一起以加大抽力。

A centrifugal fan should be used in the kitchen exhausting machine, and the exhaust duct of the kitchen should be avoided as long as possible. The exhaust duct of the kitchen should be avoided as long as possible. The draught shaft in the kitchen is better to be leaned with the exhaust duct to increase the pumping force.

通風(fēng)管道的應(yīng)用是相對比較廣泛的，但是主要還是在一些工業(yè)或者是一些類似的建筑行業(yè)中，濟(jì)南通風(fēng)管道的應(yīng)用所涉及到的領(lǐng)域也是比較多的，在很多的工業(yè)環(huán)境之類的都可以看到這樣的一種管道的存在，就像是一些以電子產(chǎn)業(yè)為主的工廠中，就有要求到需要再廠房中保持良好的凈化環(huán)境，那么就會(huì)需要這樣的一種管道來實(shí)施無塵的凈化系統(tǒng)。

Application of ventilation pipe is relatively wide, but mainly in some industries or some similar to the construction industry, the application of Ji'nan ventilation pipeline involved in the field is more, in many industrial environments such as can be seen in a pipeline that exist, as some in the electronics industry the factory, there is need to purify the environment requires good maintain the plant, it will need a pipeline to implement clean purification system.

設(shè)備通風(fēng)問題

Problem of equipment ventilation

1、主排煙管道通風(fēng)面積不夠，氣體流速過大。根據(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)行一個(gè)時(shí)期以后(如一年以后)很容易造成排煙系統(tǒng)不通暢。在油煙凈化器的運(yùn)行實(shí)踐中，大部分案例都是因排煙管道通風(fēng)面積不足引起的不通暢，管道內(nèi)氣體的流速都在15m/s以上。

1. The ventilation area of the main exhaust pipe is not enough and the gas flow velocity is too large. According to the engineering experience, the wind speed in the main pipe of the exhaust gas can not exceed 15m/s. Otherwise, after a period of operation (such as a year later), it is easy to cause the smoke exhaust system to be unobstructed. In the operation practice of oil fume purifier, most cases are not smooth due to the insufficient ventilation area of exhaust pipes, and the flow velocity of gas in pipelines is above 15m/s.

2、排煙管道由于要穿過建筑梁而使管道通風(fēng)截面積變小，截面上阻力增加，造成氣流不通暢。

2. As the exhaust pipe is to pass through the building beam, the ventilation cut area of the pipe is smaller and the resistance on the cross section increases, resulting in the unobstructed flow of the air flow.

3、排煙管道在穿過建筑梁或躲避其它設(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，由于油水混合物會(huì)積聚在較低的那段排煙管道中，直接影響排煙通暢。

3. When the exhaust pipe is passing through the building beam or avoiding other equipment pipes, a section of the exhaust pipe will be lower than the overall exhaust pipe plane. After a period of use, the oil and water mixture will accumulate in the lower exhaust pipe, which directly affects the fluency of the exhaust.

4、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通暢。

4, the kitchen fumes from different floors are discharged through the same main pipe, and the smoke exhaust from the kitchen near the outlet is better, while the kitchen exhaust of the lower floor is not smooth.
