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?

首先，在的工業廠房，很多都是用彩鋼板搭建的，散熱條件差，工作環境能夠直接影響到工人的工作效率，工作效率下降，產品質量也就保證不了。屋頂通風管道可以改變室內空氣質量，提供工作環境，增加工作效率，由于屋頂通風管道安裝在屋頂上，也不影響廠房美觀。

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，有些工業場所，因其特殊性，廠內空氣污染指數高，低劣的環境下，嚴重影響工人的身體健康，排煙通風管道可以很大程度改變廠房內空氣的質量?；馂氖鹿手?，大多數人是被濃煙嗆傷的，排煙管道可以快速排出火災事故產生的濃煙，而且必要的情況下要裝有防火閥，可以大大減輕火災事故所帶來的損失.

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

空氣是人們生活中重要的，缺少了空氣人們就會感到窒息活不下去，空氣中的氧氣也是維持人的生命基本的要素，所以要時刻保持著室內的通風，滿足人們對于氧氣的需求，這也是通風管道對于人們生活的作用。在人群密集或者相對于封閉的空間中空氣的不流通、呼出的二氧化碳等等都會使得空氣不流通，所以要時刻記得通風，尤其是在工廠中更要注意。

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.

其次是通風管道的使用可以使得良好的通風，室內的空氣流通，控制氣流的速度，什么叫做通風，也就是將室內或者是封閉空間里的污濁的空氣排出去，在工廠中將產生的有害物質都經過凈化處理之后都排出室外，然后再將新鮮空氣送入室內，稀釋空氣的有害物質，滿足人們對于空氣的需求。

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.
