排烟管道在系统分为：吸排风管、矿用抽放瓦斯管、矿用涂胶布风筒等在工业及建筑工在工厂及写字楼的空调系统，济南排烟管道小编告诉您工业污染控制用除尘、排烟、吸油等排风管、工业环境或岗位舒适用送风管。这些排烟管道按照用途的区分就是这几种，在楼房排水的管道中一般不采用排烟管道的烟管，因为雨水很容易腐蚀钢铁，所以在排水管道上一般选用pc管。
In the environmental protection system, the smoke exhaust pipe is divided into: suction and exhaust pipe, mining gas exhaust pipe, mining adhesive cloth air duct, etc. in the central air conditioning system of industrial and construction workers in factories and office buildings, the Jinan smoke exhaust pipe editor tells you that the exhaust pipe for dust removal, smoke exhaust and oil absorption for industrial pollution control, and the air supply pipe for industrial environment or post comfort. These smoke exhaust pipes are divided according to their purposes. Generally, the smoke exhaust pipes of smoke exhaust pipes are not used in the drainage pipes of buildings. Because rainwater is easy to corrode steel, PC pipes are generally used in the drainage pipes.
由两个并列矩形烟管构成，垂直穿越各楼层。
It is composed of two parallel rectangular smoke pipes and vertically crosses each floor.
次烟道在住宅每层中设一连接排油烟机的进风口，次烟道与主烟道距进风口一定距离处相汇，主烟道底层有一补风口。其原理是通过抽油烟机将烟气推入次烟道中，用抽油烟机推动力和油烟温度上浮力使油烟上升一段距离后再进入主烟道排出屋面。这样由于烟气始终向上运动，避免了烟气产生的倒灌和串味现象
The secondary flue is provided with an air inlet connecting the range hood in each floor of the residence. The secondary flue and the main flue converge at a certain distance from the air inlet, and there is a make-up air outlet at the bottom of the main flue. The principle is to push the flue gas into the secondary flue through the range hood, use the driving force of the range hood and the buoyancy of the oil fume temperature to make the oil fume rise for a certain distance, and then enter the main flue and discharge it from the roof. In this way, because the flue gas always moves upward, the backflow and cross smell of flue gas are avoided
排烟的意图是将室内的烟尘通过抽风机械排到室外,而通风是能过机械使室内外的空气进行强制流转,他们的通风方向和地点就是不同的如果已经把副烟道拆除，或是需要防止倒烟的效果更好，那么使用烟道止逆阀。一般情况下，油烟机的止逆阀效果不是很明显，而在烟道安装止逆阀可以保护油烟机，使烟道里的烟不会向管道和抽油烟机内倒灌。不过，安装止逆阀后要定期清洗，否则会使止逆阀呈打开状态，失去效果，而且烟道止逆阀建议好两年左右就更换一次。
The purpose of smoke exhaust is to exhaust the indoor smoke and dust to the outside through the exhaust machinery, and ventilation can force the air inside and outside the room through the machinery. First, their ventilation direction and location are different. If the auxiliary flue has been removed or the effect of preventing smoke pouring is better, then use the flue check valve. In general, the effect of the check valve of the range hood is not very obvious, and the installation of the check valve in the flue can protect the range hood so that the smoke in the flue will not pour back into the pipeline and range hood. However, the check valve shall be cleaned regularly after installation, otherwise the check valve will be open and lose its effect, and the flue check valve is recommended to be replaced once every two years.
通风管道材质的选择对管道的施工质量也有很大影响。一般来说，为了保证管道的重量，需要较小板厚的管道，但需要综合考虑管道的尺寸和压力水平。从设计角度来看，值得注意的是，一个系统可以同时具有对应于不同静态压力水平的几个管道厚度。风管的横向连接有一定的应力。这种连接方法可以说是延长空气导管长度的手段，并且还具有增强刚性和保持空气导管横向尺寸的功能通常，横向连接方式是角钢法兰连接。这种连接模式取决于壁厚，也取决于连接类型和板墙加固模式。预制好的风管，需要做好存放工作，以免受到二次污染。可将管口用塑料布等密封材料封住，然后将风管分门别类堆放好。使用管道前，请注意清洗作业，确认板材表面没有腐蚀，干燥后不进行清扫。。
The selection of ventilation pipe material also has a great impact on the construction quality of the pipe. Generally speaking, in order to ensure the weight of the pipeline, the pipeline with smaller plate thickness is required, but the size and pressure level of the pipeline need to be comprehensively considered. From a design point of view, it is worth noting that a system can have several pipe thicknesses corresponding to different static pressure levels at the same time. The transverse connection of air duct has certain stress. This connection method can be said to be a means to extend the length of the air duct, and also has the function of enhancing the rigidity and maintaining the transverse size of the air duct. Generally, the transverse connection method is angle steel flange connection. This connection mode depends on the wall thickness, the connection type and the plate wall reinforcement mode. The prefabricated air duct needs to be stored to avoid secondary pollution. The pipe orifice can be sealed with sealing materials such as plastic cloth, and then the air ducts can be stacked by categories. Before using the pipeline, please pay attention to the cleaning operation, confirm that the plate surface is free of corrosion, and do not clean it after drying..
