The installation of ventilation pipe is of special significance for factories and other industrial places. Moreover, the ventilation pipe can be installed on the roof, which greatly improves the appearance. Having said so much, what are the advantages?

，在的工业厂房，很多都是用彩钢板搭建的，散热条件差，工作环境能够直接影响到工人的工作效率，工作效率下降，产品质量也就保证不了。屋顶通风管道可以改变室内空气质量，提供工作环境，增加工作效率，由于屋顶通风管道安装在屋顶上，也不影响厂房美观。

First of all, in our industrial plants, many of them are built with color steel plate, the heat dissipation condition is poor, the working environment can directly affect the work efficiency of workers, the work efficiency drops, and the product quality can not be guaranteed. The roof ventilation pipe can change the indoor air quality, provide the working environment and increase the work efficiency. Because the roof ventilation pipe is installed on the roof, it does not affect the beauty of the factory.

其次，有些工业场所，因其特殊性，厂内空气污染指数高，低劣的环境下，严重影响工人的身体健康，排烟通风管道可以很大程度改变厂房内空气的质量。火灾事故中，大多数人是被浓烟呛伤的，排烟管道可以快速排出火灾事故产生的浓烟，而且必要的情况下要装有防火阀，可以大大减轻火灾事故所带来的损失.

Secondly, due to the particularity of some industrial places, the air pollution index in the factory is high. Under the poor environment, the health of workers is seriously affected. The smoke exhaust and ventilation pipes can greatly change the air quality in the factory. In the fire accident, most people are choked by the thick smoke. The smoke exhaust pipe can quickly discharge the thick smoke from the fire accident, and the fire damper should be installed if necessary, which can greatly reduce the loss caused by the fire accident

空气是人们生活中重要的，缺少了空气人们就会感到窒息活不下去，空气中的氧气也是维持人的生命基本的要素，所以要时刻保持着室内的通风，满足人们对于氧气的需求，这也是通风管道对于人们生活的作用。在人群密集或者相对于封闭的空间中空气的不流通、呼出的二氧化碳等等都会使得空气不流通，所以要时刻记得通风，尤其是在工厂中更要注意。

Air is an important part of people's life. Without air, people will feel suffocated and unable to live. The oxygen in the air is also the basic element to maintain people's life, so we should always maintain indoor ventilation to meet people's demand for oxygen, which is also the role of ventilation pipes in people's life. In a crowded or closed space, the air will not circulate, the exhaled carbon dioxide and so on, so always remember to ventilate, especially in the factory.

其次是通风管道的使用可以使得良好的通风，室内的空气流通，控制气流的速度，什么叫做通风，也就是将室内或者是封闭空间里的污浊的空气排出去，在工厂中将产生的有害物质都经过净化处理之后都排出室外，然后再将新鲜空气送入室内，稀释空气的有害物质，满足人们对于空气的需求。

Secondly, the use of ventilation duct can make good ventilation, indoor air circulation, control the speed of air flow, what is called ventilation, that is, the dirty air in the indoor or enclosed space is discharged, the harmful substances produced in the factory are discharged out of the room after purification treatment, and then fresh air is sent into the room to dilute the harmful substances in the air, Meet people's needs for air.
