但在實際運行過程中，仍有不少餐飲單位達不到國家排放標準，其中除了不自覺地安裝油煙凈化設備，不按要求正常使用外，還有部分是由于廚房排氣系統設計不合理造成的。
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.
廚房排煙系統與油煙凈化器的匹配是油煙凈化器有效凈化的保證，直接影響餐飲單位廚房油煙排放能否達標。我們知道，油煙凈化器本質上只處理油煙。如果廚房排氣系統設計不合理，油煙無法通過凈化器，即使安裝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.

設計合理、功能齊全的濟南廚房排煙設備凈化系統應同時具備以下功能：
A reasonably designed and fully functional Jinan kitchen smoke exhaust equipment purification system should simultaneously have the following functions:
首先，它可以捕獲和消除廚房設備產生的所有油煙、蒸汽、燃燒廢氣，以及一些設備產生的多余熱量。根據排氣扇的總量和廚房門、窗戶、過道的自然風量，可以合理分配新鮮空氣的供應，使廚房內部空間保持略負的氣壓狀態。能有效凈化廚房油煙、蒸汽和廢氣，符合國家標準。通過對系統技術指標的綜合分析，如流量，風壓、熱量等。進行平衡優化設計，使系統工作能夠達到節能減排降噪的目的。
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，對于用于廚房排煙和新風供應的管道，系統管道應具有減震和消聲功能，因為管道系統管道中的風扇等設備會產生一定的噪音和振動，管道的進風口和出風口也會產生氣流的嘯聲。因此，管道系統應配備適當的減震和消聲裝置。
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.
系統管線的布置和走向應根據場地的空間結構和實際需求進行布置。管道的方向應盡量縮短，切直，并充分利用風機、凈化器、除臭器等設備進出口軸線的夾角來代替或減少彎頭的應用，以降低管道系統的阻力。
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.
總的來說，合理的廚房排煙系統對餐飲單位達到排放標準非常重要，在設需要更多的關注。
Overall, a reasonable kitchen smoke exhaust system is crucial for catering units to meet emission standards and requires more attention in design.
