However, in the actual operation process, there are still many catering units that cannot meet the national emission standards. In addition to unconsciously installing oil fume purification equipment and not using it normally according to requirements, there are also some that are caused by the unreasonable design of the kitchen exhaust system.

厨房排烟系统与油烟净化器的匹配是油烟净化器有效净化的保证，直接影响餐饮单位厨房油烟排放能否达标。我们知道，油烟净化器本质上只处理油烟。如果厨房排气系统设计不合理，油烟无法通过净化器，即使安装了也起不到任何作用。

The matching of kitchen smoke exhaust system and oil fume purifier is a guarantee for effective purification of oil fume purifier, which directly affects whether the kitchen oil fume emissions of catering units can meet the standards. We know that oil fume purifiers essentially only handle oil fume. If the design of the kitchen exhaust system is not reasonable, the oil fume cannot pass through the purifier, and even if installed, it will not have any effect.

设计合理、功能齐全的济南厨房排烟设备净化系统应同时具备以下功能：

A reasonably designed and fully functional Jinan kitchen smoke exhaust equipment purification system should simultaneously have the following functions:

，它可以捕获和厨房设备产生的所有油烟、蒸汽、燃烧废气，以及一些设备产生的多余热量。根据排气扇的总量和厨房门、窗户、过道的自然风量，可以合理分配新鲜空气的供应，使厨房内部空间保持略负的气压状态。能有效净化厨房油烟、蒸汽和废气，符合标准。通过对系统技术指标的综合分析，如流量，风压、热量等。进行平衡优化设计，使系统工作能够达到减排降噪的目的。

Firstly, it can capture and eliminate all oil fumes, steam, combustion gases, and excess heat generated by kitchen equipment. According to the total amount of exhaust fans and the natural airflow of kitchen doors, windows, and aisles, the supply of fresh air can be reasonably distributed to maintain a slightly negative air pressure state in the interior space of the kitchen. It can effectively purify kitchen fumes, steam, and exhaust gases, meeting national standards. Through comprehensive analysis of system technical indicators, such as flow rate, wind pressure, heat, etc. Conduct balanced optimization design to achieve the goal of energy conservation, emission reduction, and noise reduction in system operation.

此外，对于用于厨房排烟和新风供应的管道，系统管道应具有减震和消声功能，因为管道系统管道中的风扇等设备会产生一定的噪音和振动，管道的进风口和出风口也会产生气流的啸声。因此，管道系统应配备适当的减震和消声装置。

In addition, for the ducts used for kitchen smoke exhaust and fresh air supply, the system ducts should have shock absorption and noise reduction functions, as the fans and other equipment in the duct system ducts can generate certain noise and vibration, and the air inlet and outlet of the ducts can also produce airflow whistling. Therefore, the pipeline system should be equipped with appropriate shock absorption and noise reduction devices.

系统管线的布置和走向应根据场地的空间结构和实际需求进行布置。管道的方向应尽量缩短，切直，并充分利用风机、净化器、除臭器等设备进出口轴线的夹角来代替或减少弯头的应用，以降低管道系统的阻力。

The layout and direction of system pipelines should be based on the spatial structure and actual needs of the site. The direction of the pipeline should be shortened as much as possible, cut straight, and fully utilize the angle between the inlet and outlet axes of equipment such as fans, purifiers, and deodorizers to replace or reduce the application of elbows, in order to reduce the resistance of the pipeline system.

总的来说，合理的厨房排烟系统对餐饮单位达到排放标准非常重要，在设需要更多的关注。

Overall, a reasonable kitchen smoke exhaust system is crucial for catering units to meet emission standards and requires more attention in design.
