来源:http://www.jnqsg.com/     发布时间:2022-06-10  

说到食堂,就会想到食堂排烟罩。 呼吸着油烟的大个子特别吸睛。 下面说说食堂通风柜排烟量的确定和设计。
When it comes to the canteen, you will think of the smoke exhaust hood of the canteen. The big man who breathed the lampblack was very eye - catching. Let's talk about the determination and design of the smoke exhaust volume of the fume hood in the canteen.
为保证净化效果,在实际设计中,排风量严格按照食堂排烟罩和抽排烟罩的抽风风速计算,抽排烟罩的抽风风速通常不小于 0.5米/秒。 很小排风量通常由下式计算:L=2000PH
In order to ensure the purification effect, in the actual design, the exhaust air volume is calculated in strict accordance with the exhaust wind speed of the canteen exhaust hood and the exhaust hood. The exhaust wind speed of the exhaust hood is usually not less than 0.5 m / s. Very small exhaust air volume is usually calculated by the following formula: l=2000ph
式中:L——食堂通风柜排风量,m3/h;
Where: L - exhaust air volume of canteen ventilator, m3/h;
P——食堂排烟罩口周长(靠墙侧不计),m;
P - perimeter of smoke exhaust hood of canteen (not counting the side near the wall), m;
H——食堂排烟罩口到炉口的距离,m。
H - distance from smoke exhaust hood of canteen to furnace mouth, M.
用上式计算排风量,再根据食堂排烟罩的面积计算抽排烟罩的抽风速度,保证抽排烟罩的抽风速度不小于0.5m/s。
Use the above formula to calculate the exhaust volume, and then calculate the exhaust speed of the exhaust hood according to the area of the canteen exhaust hood, so as to ensure that the exhaust speed of the exhaust hood is not less than 0.5m/s.
在实际工程设计中,经常使用估算法。 根据《民用建筑暖通空调设计技术办法》中对厨房通风量的规定,厨房通风量也可按以下通风次数确定:
Estimation method is often used in practical engineering design. According to the provisions on the kitchen ventilation volume in the technical measures for HVAC design of civil buildings, the kitchen ventilation volume can also be determined according to the following ventilation times:

中式厨房:L=40-50(次/小时);
Chinese Kitchen: l=40-50 (times / hour);
西厨:L=30-40(次/h);
Western Kitchen: l=30-40 (times /h);
员工餐厅:L=25-35(次/小时)。
Staff restaurant: l=25-35 (times / hour).
食堂抽排烟罩特点:
Features of smoke exhaust hood in canteen:
可有效阻隔油烟和气味达95%和70%,能有效解决空气污染和墙体污染问题。
It can effectively block oil smoke and odor up to 95% and 70%, and can effectively solve the problems of air pollution and wall pollution.
食堂通风柜具有防火功能,使气喉避免受热扩散。
The fume hood in the canteen has the function of fire prevention, so that the air pipe can avoid thermal diffusion.
食堂排烟罩可以降低炉灶温度,为厨师提供更有利的工作环境。
The smoke exhaust hood of the canteen can reduce the temperature of the stove and provide a more favorable working environment for chefs.
济南排烟罩厂家认为食堂排烟罩外观美观耐用,油污不易积聚。
Jinan smoke exhaust hood manufacturer believes that the appearance of the smoke exhaust hood in the canteen is beautiful and durable, and oil pollution is not easy to accumulate.
