酒店廚房安裝油煙凈化器通風排煙工程系統布置的不合理，會直接影響廚房通風排煙不順暢，廚房通風排煙工程的系統該如何設計，才能避免這一現象呢？
濟南廚房排煙廠家結合相關案例，整理了以下幾點，供大家參考。
The unreasonable layout of the ventilation and smoke exhaust engineering system for installing oil fume purifiers in the hotel kitchen will directly affect the smooth ventilation and smoke exhaust in the kitchen. How can the system of the kitchen ventilation and smoke exhaust engineering be designed to avoid this phenomenon? Jinan kitchen smoke exhaust manufacturers have sorted out the following points in combination with relevant cases for your reference.
1、廚房安裝油煙凈化器防排煙工程中管道的水平段不宜太長。尤其安裝上油煙凈化器裝置風阻會加大，一般水平遠距離不應超過15m并且要有2%以上的坡度，水平末端設活接頭，以方便清理管道內油垢。新建廚房的油煙凈化器安裝盡量安裝在廚房近端排煙風機的前面以減少排煙管道及風機葉輪的油煙附著，延長管道清洗及風機的維護周期。接排風罩的支管應設風量調節閥。
1. The horizontal section of the pipe in the smoke control and exhaust project of the kitchen installed with the range hood purifier should not be too long. In particular, when the oil fume purifier is installed, the wind resistance will increase. Generally, the horizontal distance should not exceed 15m and there should be a slope of more than 2%. The horizontal end should be provided with a union to facilitate the cleaning of oil dirt in the pipeline. The lampblack purifier in the newly-built kitchen shall be installed in front of the smoke exhaust fan at the near end of the kitchen as far as possible to reduce the lampblack adhesion of the smoke exhaust pipe and fan impeller, and extend the pipe cleaning and fan maintenance period. The branch pipe connected to the exhaust hood shall be provided with an air volume control valve.
2、廚房送風系統應為直流方式，廚房的通風工程系統宜采用變速風機或關聯又風機進行送排風。
2. The air supply system of the kitchen shall be DC, and the ventilation engineering system of the kitchen shall adopt variable-speed fans or associated fans for air supply and exhaust.
3、廚房油煙凈化器裝置選型應該根據廚房排風及灶頭數量品配。排煙口布置廚房內送、排風口的布置應按灶具的具體位置加以考慮，不能讓送風口對準廚師的頭部吹風，避免影響廚師的身體健康及送風射流擾亂灶具的排風性能。
3. The selection of kitchen range hood purifier should be based on the quantity of kitchen exhaust and stove. The arrangement of smoke exhaust outlet: the arrangement of air supply and exhaust outlets in the kitchen should be considered according to the specific position of the cooker. The air supply outlet should not be directed at the chef's head to blow air, so as to avoid affecting the chef's health and disturbing the exhaust performance of the cooker by the air supply jet.
確定送風出口的出口風速時，在距地2m左右時的區域風速<0.25m>較為理想。廚房油煙凈化器裝置安裝通風排煙工程中送風口應沿排風罩方向布置，離開罩子前方小0.7m，而排風口距排風罩越遠越好。每個炒菜廚房須有崗位送風。
When determining the outlet wind speed of the air supply outlet, the regional wind speed < 0.25m > at a distance of about 2m from the ground is ideal. In the installation of kitchen lampblack purifier, the air supply outlet shall be arranged along the direction of the exhaust hood, 0.7m away from the front of the hood, and the farther the exhaust outlet is from the exhaust hood, the better. Each cooking kitchen must have post air supply.
4、機房、風機及風管的布置廚房的排風機宜設在廚房的上部，廚房為公共建筑中的一部分時，其排風機宜設在屋，這可以使風道內處于負壓狀態，避免氣味外溢。
4. Arrangement of machine room, fan and air duct: the exhaust fan of the kitchen should be set at the upper part of the kitchen. When the kitchen is a part of a public building, the exhaust fan should be set at the roof level, which can make the air duct in a negative pressure state and avoid odor leakage.
廚房排煙風口盡量離室內空調系統通風口遠點，避免廚房氣味與空調系統串流，影響空調系統的空氣質量。廚房的排風機一般應選用低噪音離心風機。油煙凈化器裝置、風機與風管鏈接盡量選擇軟連接，減少風機運行時連帶管道產生噪音影響周圍居民。
The smoke exhaust outlet of the kitchen shall be far away from the vent of the indoor air conditioning system as far as possible to prevent the kitchen odor from flowing with the air conditioning system and affecting the air quality of the air conditioning system. Low noise centrifugal fan shall be selected as the exhaust fan of the kitchen. Soft connection shall be selected as far as possible for the hood purifier device, the fan and the air duct, so as to reduce the noise generated by the fan and the associated pipes from affecting the surrounding residents.
必要的情況下排煙管道加裝降噪處理。廚房的排風豎井好與防排煙工程的管道靠在一起以加大抽力。
If necessary, the smoke exhaust pipe shall be equipped with noise reduction treatment. The exhaust shaft of the kitchen should be close to the pipes of the smoke control project to increase the pumping force.
How to design the system of kitchen ventilation and smoke exhaust project? We explained the problem through the above four aspects. We hope it will be helpful to you. Please come to our website for more information http://m.pvcbox.cn Take a look.
