关于通风管道的送风方式

来源:http://www.jntfgd.com 日期:2021-01-15 发布人:gaoshitongferng

通风管道是特地为一处或几处房间或设备送风和排风的管道。排烟管道是特地共排烟气的管道,就用途来讲有分别,就管道自身讲都是管道。 装置完的风管要保证外表润滑干净,室外风管应有防雨、防雪措施。 风管伸入构造风道时,其末端应装置上钢板网,避免系统运转时,杂物进入金 属风管内。金属风管与构造风道缝隙应封堵紧密。
Ventilation duct is a kind of duct specially used to supply and exhaust air for one or several rooms or equipment. The smoke exhaust pipe is a pipe specially designed to exhaust smoke. It is different in terms of use, and it is a pipe in terms of the pipe itself. The air duct after installation shall be lubricated and clean, and the outdoor air duct shall be provided with rain proof and snow proof measures. When the air duct extends into the structural air duct, steel mesh shall be installed at the end of the air duct to prevent the sundries from entering into the metal air duct during the operation of the system. The gap between metal air duct and structural air duct should be sealed tightly.
风管穿越沉降缝时应按设计请求加设套管,套管与风管的间隙用填料(软质)封 堵紧密,从这些特性我们应该能够很快的辨别开两者的区别。
When the air duct passes through the settlement joint, the casing should be added according to the design requirements, and the gap between the casing and the air duct should be tightly sealed with filler (soft). From these characteristics, we should be able to quickly distinguish the difference between the two.
厨房室内的管道布置要遵循“短”原则,少用弯头,尤其是大角度弯头,这种布管方式和空调的“横竖整齐”有所不同,目的是保障排油烟效果,还可以节省。烟罩上面的集气管的主出口 烟罩的中部位置。
The pipeline layout in the kitchen should follow the "short" principle, and use less elbows, especially large angle elbows. This kind of pipe layout is different from the "vertical and horizontal neat" of the air conditioner, so as to ensure the effect of exhaust fumes and save energy. The central position of the main outlet hood of the air collecting pipe above the hood.
厨房所在建筑物高度小于等于15m时,油烟排放口应高出屋顶。原则上要高出建筑物2m以上。建筑物高度大于15m时,油烟排烟口高度应大于15m。
When the height of the building where the kitchen is located is less than or equal to 15m, the oil fume outlet shall be higher than the roof. In principle, it should be more than 2m higher than the building. When the height of the building is more than 15m, the height of the oil smoke outlet should be more than 15m.
排风管的室外排气口上应安装受室外风压影响小的管帽(管罩)制成品。按换气次数确定排风量。各家厨房差别较大,厨房面积与厨具、炉灶的数量不成正比,同样灶的产生的污染物和热量也 差别很大。
The outdoor exhaust outlet of the exhaust pipe shall be installed with the pipe cap (pipe cover) which is less affected by the outdoor wind pressure. Determine the exhaust volume according to the ventilation frequency. The kitchen area is not directly proportional to the number of kitchenware and stoves, and the pollutants and heat produced by the same stoves are also very different.
实际上厨房通风并非是全面通风,按换气次数设计风量会有很大的误差。
In fact, kitchen ventilation is not comprehensive ventilation, according to the number of ventilation design air volume will have a great error.
