当一个酒店厨房正常运作时会产生大量的垃圾，油烟等，这时候我们设计师就需要考虑到怎样排放垃圾，厨房油烟怎么排放才能达到对于整个酒店周围的环境影响更小，即怎么设计排烟管道。
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、厨房补风 由于厨房所在建筑物的格局以及厨房在建筑物中的位置不同,有条件的厨房应由建筑物的集中空调系统进行有序送风。但目前所遇到的大部分情况是建筑物没有设置厨房的送风系统。许多带餐厅、厨房等的建筑物,仅设计了集中采暖系统而无集中空调系统。当厨房处于工作状态时,排风系统投入运行,厨房内处于负压状态,新风来源包括室外新风渗透和餐厅的空气大量补入厨房。
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、厨房油烟排风量的确定 为了保证净化效果,在实际设排烟风量要求严格按照排风罩的吸入风速计算,罩口的吸风速度通常不低于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、济南酒店厨房排烟安装人员采用的送风系统应为直流方式,厨房的通风系统宜采用变速风机或关联又风机进行送排风。送排风口布置:厨房内送、排风口的布置应按灶具的具体位置加以考虑,不要让送风射流扰乱灶具的排风性通。确定送风出口的出口风速时,在距地2m左右时的区域风速。
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.
房排烟管道的水平段不宜太长，一般水平更远距离不应超过15m并且要有2%以上的坡度，水平末端设活接头，以方便清理油垢。排风速度按规范不得低于 10ms,以防风速过低使油附着于烟道上，接排风罩的支管应设风量调节阀。
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. 上一篇：济南通风管道设备的在何处
