来源:http://www.doqa19.com 日期:2020-08-31 发布人:gaoshitongferng

厨房排烟风机排烟罩除消防排烟风机管道的防火阀之外,考虑到厨房高温工作的原因。其余风机管道的防火阀建议安装150℃防火阀(与平时普通风机管道装置的70℃略有不同),需关闭其余所有风机(消防补风靠外窗及门隙等地方进风)当消防排烟风机动作时;当开启“排油烟风机”时,需同时(联动)开启“油烟罩补风风机”与“工作区新风预处理风机”。
In addition to the fire damper of the fire exhaust fan pipe, the high temperature operation of the kitchen is considered. It is recommended to install 150 ℃ fire damper for other fan pipes (slightly different from the 70 ℃ of ordinary fan duct installation), It is necessary to turn off all other fans (the fire-fighting make-up air is close to the external windows and door gaps) when the fire-fighting smoke exhaust fan is in operation; when the "oil fume exhaust fan" is turned on, the "oil fume hood make-up fan" and the "fresh air pretreatment fan in the working area" should be started simultaneously (linkage).
排烟阀平时常关,火灾时开,与报警主机联动,开启条件是自动报警系统发生火警(探测器报警)消防报警主机置于自动状态,排烟阀自动开启,联动排烟风机启动。排烟防火阀是平时常开,火灾时也是开启状态,但当烟气温度达到280℃时,排烟防火阀自动关闭,联动已经开启的风机停止运行。

The smoke exhaust valve is normally closed at ordinary times and opened in case of fire, which is linked with the alarm host. The opening condition is that the automatic alarm system has a fire alarm (detector alarm), the fire alarm host is in automatic state, the smoke exhaust valve is opened automatically, and the linkage smoke exhaust fan is started. The smoke exhaust fire damper is normally open at ordinary times and is also open in case of fire. However, when the flue gas temperature reaches 280 ℃, the smoke fire damper will automatically close and the fan that has been opened will stop running.

Jinan kitchen smoke exhaust
济南厨房排烟使用说明:一般用于厨房的风机排烟罩有会带走厨房大量空气,油烟罩补风风机—抽油烟时,需向厨房补充空气,该机提供约占排油烟风量的80%。工作区新风预处理风机—为厨房工作区(人员工作位置)提供经过预处理的新风。该机提供约占排油烟风量的20%排油烟风机—排去煮食区油烟罩的油气。
Jinan kitchen smoke exhaust instructions: generally used in the kitchen fan exhaust hood will take away a large amount of kitchen air, lampblack hood air supplement fan - when pumping oil smoke, it needs to supplement air to the kitchen, which provides about 80% of the oil fume exhaust volume. Working area fresh air pre-treatment fan - provides pre-treatment fresh air for kitchen work area (staff working position). This machine provides about 20% of the oil fume exhaust air volume, which exhausts the oil and gas from the cooking area hood.
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。
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 for orderly air supply 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.
如果是新建项目,在设要充分考虑安装了油烟净化器后对排风系统的影响;如果是改造项目,在加装油烟净化器时需要对排风系统重新进行核算,必要时要对集烟罩、排烟管道和厨房整体补风装置进行改造并更换排烟风机。
If it is a new project, the impact of the installation of oil fume purifier on the exhaust system should be fully considered in the design; if it is a reconstruction project, the exhaust system needs to be recalculated when the oil fume purifier is installed, and if necessary, the smoke collecting hood, smoke exhaust pipe and kitchen integral air supplement device shall be reconstructed and the smoke exhaust fan shall be replaced.
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。
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.
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
The ventilation system of kitchen 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 上一篇:通风管道有哪些机械通风原则呢?
