當一個酒店廚房正常運作時會產生大量的垃圾，油煙等，這時候我們設計師就需要考慮到怎樣排放垃圾，廚房油煙怎么排放才能達到對于整個酒店周圍的環境影響更小，即怎么設計排煙管道。
When a hotel kitchen is in normal operation, a lot of garbage and lampblack will be produced. At this time, we designers need to consider how to discharge garbage and how to discharge kitchen fume to minimize the impact on the environment around the hotel, that is, how to design smoke exhaust pipes.
1、廚房補風 由于廚房所在建筑物的格局以及廚房在建筑物中的位置不同,有條件的廚房應由建筑物的集中空調系統進行有序送風。但目前所遇到的大部分情況是建筑物沒有設置廚房的送風系統。許多帶餐廳、廚房等的建筑物,僅設計了集中采暖系統而無集中空調系統。當廚房處于工作狀態時,排風系統投入運行,廚房內處于負壓狀態,新風來源包括室外新風滲透和餐廳的空氣大量補入廚房。
1. Due to the different structure of the building where the kitchen is located and the location of the kitchen in the building, the centralized air conditioning system of the building should be used to supply air in the kitchen with conditions. But at present, most of the situation is that there is no kitchen air supply system in the building. Many buildings with restaurants, kitchens and so on have only designed central heating system without central air conditioning system. When the kitchen is in working state, the exhaust system is put into operation, and the kitchen is in a negative pressure state. The fresh air sources include outdoor fresh air infiltration and large amount of air from dining room.
2、廚房油煙排風量的確定 為了保證凈化效果,在實際設排煙風量要求嚴格按照排風罩的吸入風速計算,罩口的吸風速度通常不低于0.5m/s。
2. In order to ensure the purification effect, in the actual design, the exhaust air volume should be calculated in strict accordance with the suction wind speed of the exhaust hood, and the suction speed of the hood mouth is usually not less than 0.5m/s.
3、
濟南酒店廚房排煙安裝人員采用的送風系統應為直流方式,廚房的通風系統宜采用變速風機或關聯又風機進行送排風。送排風口布置:廚房內送、排風口的布置應按灶具的具體位置加以考慮,不要讓送風射流擾亂灶具的排風性通。確定送風出口的出口風速時,在距地2m左右時的區域風速。
3. The air supply system adopted by Jinan hotel kitchen smoke exhaust installation personnel should be DC mode, and the kitchen ventilation system should adopt variable speed fan or associated fan for air supply and exhaust. Air supply and exhaust outlet arrangement: the arrangement of air supply and exhaust outlets in the kitchen should be considered according to the specific position of the stove, and the air supply jet should not disturb the ventilation performance of the stove. When determining the outlet wind speed of the air supply outlet, the regional wind speed is about 2m away from the ground.
房排煙管道的水平段不宜太長，一般水平更遠距離不應超過15m并且要有2%以上的坡度，水平末端設活接頭，以方便清理油垢。排風速度按規范不得低于 10ms,以防風速過低使油附著于煙道上，接排風罩的支管應設風量調節閥。
The horizontal section of smoke exhaust pipe should not be too long. Generally, the maximum horizontal distance should not be more than 15m, and there should be a slope of more than 2%. The horizontal end should be provided with a movable joint to facilitate the cleaning of oil dirt. The exhaust speed shall not be less than 10ms according to the specification, so as to prevent the oil from adhering to the flue due to too low wind speed. The branch pipe connecting the exhaust hood shall be equipped with air volume regulating valve.
