排烟管道的设计和安装不合理，往往会造成厨房排烟不通畅，直接影响油烟净化器的使用。对于餐饮业的厨房来说，排烟是否通畅直接关系到厨房能否正常工作，油烟净化则只是厨房排烟系统中的一个净化空气的强制性功能。排烟系统和净化器的合理匹配是保证油烟净化器净化效率的关键，同时也是油烟净化器设计人员容易忽略的问题，如果排烟系统设计不合理而造成整个厨房排烟不畅，则将无法安装油烟净化器，即使安装了油烟净化器也无法正常工作。
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.
厨房的排风机一般应选用离心风机，厨房的排风管应尽量避免过长的水平风道。厨房的排风管应尽量避免过长的水平风道。厨房的排风竖井好与排烟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.
通风管道的应用是相对比较广泛的，但是主要还是在一些工业或者是一些类似的建筑行业中，济南通风管道的应用所涉及到的领域也是比较多的，在很多的工业环境之类的都可以看到这样的一种管道的存在，就像是一些以电子产业为主的工厂中，就有要求到需要再厂房中保持良好的净化环境，那么就会需要这样的一种管道来实施无尘的净化系统。
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.
设备通风问题
Problem of equipment ventilation
1、主排烟管道通风面积不够，气体流速过大。根据工程经验，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。在油烟净化器的运行实践中，大部分案例都是因排烟管道通风面积不足引起的不通畅，管道内气体的流速都在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、排烟管道由于要穿过建筑梁而使管道通风截面积变小，截面上阻力增加，造成气流不通畅。
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、排烟管道在穿过建筑梁或躲避其它设备管道时，排烟管道中的一段会低于整体排烟管道平面。在使用一段时间后，由于油水混合物会积聚在较低的那段排烟管道中，直接影响排烟通畅。
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、不同楼层的厨房油烟通过同一主管道排出，离出口近的楼层厨房排烟效果较好，而较低楼层的厨房排烟不通畅。
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.
