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.

消防排煙管道安裝

Installation of fire smoke exhaust pipe

一、工業廠房自然通風方法分排風系統及吹風機兩類，基本原理關鍵分成壓合自然通風及其氣壓自然通風。

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.

二、因為自然風遭受當然標準的限定，具備不穩定性，為不可控性。可是具體情況毫無疑問是壓合自然通風及其氣壓自然通風另外功效，具體情況也就好于只探討壓合自然通風的狀況。

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.

三、要確保空氣流通的暢順、充足，標準是有充足大規模的進氣口、通風口，而且布局進、通風口及其設計方案進、出氣口總面積。

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.

四、換風就是說讓工業廠房內的氣旋超過水流量，在只探討壓合自然通風的狀況下，由于是生產流水線定形生產制造，因此工業廠房內生產制造主題活動造成的余熱回收在周期時間內能夠 覺得是不會改變的，造成的余熱回收在小范圍之內汽體溫度轉變一致。

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.

五、在考慮到造成的余熱回收不會改變、氣體的各物理學特點不會改變的狀況下，就會獲得外部溫度越低，工業廠房內的氣旋水流量就會越高，就是說具體條件下，外部溫度減少，工業廠房內換風就會相對增加。

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.

七、布局進氣口、通風口在房屋建筑的部位。

7、 The air inlets and vents are arranged in the building.
