The middle of the ventilation duct and the oil fume exhaust duct belong to the pipeline, but the key difference is in the main purpose. The oil fume exhaust duct is used as the pipeline to remove smoke and dust, and the key function of the ventilation duct is the exhaust and smoke exhaust system, which is common in one or several rooms or machinery and equipment. The differences between them are mainly reflected in their characteristics.

风管安装进行后，要确保表层光洁无别的残渣，而针对处在户外一部分的通风风管必须防雪、防水防雨等对策。在穿越重生变形缝时通风风管必须依据设计方案增设防水套管，通风风管和防水套管中间的间隙必须用填充料堵漏认真细致。她们分别都有哪些特性呢？我们要如何充分准备工作中呢？山东省通风管道系统软件的设计方案、通风风管运送和维护保养有什么事宜必须留意、通风风管的主要用途等。在其中提及通风风管的功效关键有自然通风、排烟系统、运送等主要用途。

After the installation of the air duct, ensure that the surface is clean and free of other residues, and the ventilation air duct located outdoors must be snow proof, waterproof and rainproof. When crossing the regeneration deformation joint, the ventilation air duct must be added with waterproof casing according to the design scheme, and the gap between the ventilation air duct and waterproof casing must be blocked with filler carefully. What are their characteristics? How can we fully prepare for the work? The design scheme of ventilation duct system software in Shandong Province, what matters must be paid attention to in the transportation and maintenance of ventilation duct, the main purpose of ventilation duct, etc. The key functions of ventilation duct mentioned therein include natural ventilation, smoke exhaust system, transportation and other main purposes.

Shandong ventilation duct

次序式烟道横截面上由2个并排矩形框排风管组成，竖直穿越重生各楼。次烟道在住房各层中设一联接排油烟机的进气口，山东省通风管道的次烟道与主烟道距进气口一定距离处相汇，主烟道层有一补出风口。其基本原理是根据抽油烟机将烟尘送入次烟道中，用抽油烟机驱动力和油烟溫度上水的浮力使油烟升高一段距离后再进到主烟道排出来平屋面。

The cross section of the sequential flue is composed of two side-by-side rectangular frame exhaust ducts, which vertically pass through the regeneration buildings. The secondary flue is provided with an air inlet connecting the range hood in each floor of the house. The secondary flue of the ventilation pipeline in Shandong Province meets with the main flue at a certain distance from the air inlet, and the main flue layer is provided with a supplementary air outlet. The basic principle is that the smoke and dust is sent into the secondary flue according to the range hood, and the oil smoke is raised for a certain distance by the driving force of the range hood and the buoyancy of the oil smoke temperature and water, and then into the main flue and discharged out of the flat roof.

由一个简易的矩形框排风管组成，竖直穿越重生各层住房，在各层住房中留出一个联接抽油烟机的进气口，层由一个补出风口补气血。其基本原理是各层烟尘在抽油烟机的促进下，将油烟排进烟道中，因为烟尘溫度的功效，在烟道中造成升高水的浮力，从出平屋面的通风口将烟尘排出来。

It is composed of a simple rectangular frame exhaust pipe, which vertically passes through the houses on each floor of regeneration. An air inlet connected with the range hood is reserved in the houses on each floor, and an air outlet is used to supplement qi and blood. The basic principle is that each layer of smoke and dust will be discharged into the flue under the promotion of the range hood. Because of the effect of smoke and dust temperature, it will cause the buoyancy of rising water in the flue and discharge the smoke and dust from the vent out of the flat roof.
