The application of fire smoke exhaust and ventilation ducts in processing plants is very common, but the fire smoke exhaust and ventilation ducts used in processing plants have some problems, such as unscientific design scheme and non-standard installation. Then people will follow the fire smoke exhaust duct to deeply analyze the design scheme and installation key points of the fire smoke exhaust and ventilation duct.
Installation of fire smoke exhaust pipe
1、 The natural ventilation methods of industrial plants are divided into two types: exhaust system and blower. The basic principle is divided into pressure natural ventilation and pneumatic natural ventilation.
2、 Because the natural wind is limited by the natural standard, it is unstable and uncontrollable. However, there is no doubt that the specific situation is the additional effect of compressed natural ventilation and pneumatic natural ventilation. The specific situation is better than just discussing the situation of compressed natural ventilation.
3、 To ensure smooth and sufficient air circulation, the standard is to have sufficient large-scale air inlets and vents, and to layout the total area of air inlets and vents and their design schemes.
4、 Air change means to make the cyclone in the industrial plant exceed the water flow. Under the condition of only discussing the pressure natural ventilation, due to the production line shaping production and manufacturing, the waste heat recovery caused by the production and manufacturing theme activities in the industrial plant can be felt to be unchanged within the cycle time, and the resulting waste heat recovery is consistent with the change of steam temperature in a small range.
5、 Considering that the waste heat recovery will not change and the physical characteristics of the gas will not change, it will be obtained that the lower the external temperature, the higher the cyclone water flow in the industrial plant, that is to say, under specific conditions, if the external temperature decreases, the air exchange in the industrial plant will increase relatively.
六、自然通風進出口貿易的總面積能夠 在設計方案測算上依據基礎理論推斷能夠 獲得一個大約的范疇數，而工業廠房內的氣旋水流量則需要依據具體情況數次實驗才會有近似值。
6、 The total area of natural ventilation import and export trade can be estimated according to the basic theory on the basis of design scheme calculation, while the cyclone water flow in the industrial plant needs several experiments according to the specific situation to have an approximate value.
7、 The air inlets and vents are arranged in the building.
