川消氣體滅火系統(tǒng)優(yōu)化設(shè)計的考慮
來源：http://www.xintli.net/ 日期：2022-12-09
我們都知道氣體滅火系統(tǒng)很復(fù)雜，不是有一個初步的圖紙就可以直接按原始圖紙采購了，還需要廠家進行進一步的優(yōu)化設(shè)計。這不僅關(guān)系到后續(xù)的成本，還關(guān)系到氣體滅火系統(tǒng)能否順利通過驗收。那么，氣體滅火系統(tǒng)優(yōu)化設(shè)計要從哪些方面考慮？
川消廠家為您解答。
As we all know, the gas fire extinguishing system is very complex. It is not necessary to purchase according to the original drawings without a preliminary drawing. The manufacturer needs to further optimize the design. This is not only related to the subsequent cost, but also related to the successful acceptance of the gas fire extinguishing system. So, what aspects should be considered in the optimization design of gas fire extinguishing system? The manufacturer of Chuanxiao will answer for you.
一、系統(tǒng)綜合性設(shè)計優(yōu)化
1、 System comprehensive design optimization
想要將氣體滅火系統(tǒng)的功能優(yōu)勢完全發(fā)揮出來，很重要的一個因素便是做好設(shè)計管理，保證每一個細(xì)節(jié)參數(shù)的準(zhǔn)確性，為各設(shè)備構(gòu)件的安裝施工提供可靠依據(jù)。
If you want to give full play to the functional advantages of the gas fire extinguishing system, an important factor is to do a good job in design management, ensure the accuracy of each detailed parameter, and provide a reliable basis for the installation and construction of each equipment component.
二、管網(wǎng)與噴嘴設(shè)計
2、 Pipe network and nozzle design
以七氟丙烷滅火系統(tǒng)為例，七氟丙烷在管道內(nèi)是以壓縮氣體的形式進行輸送的，因為液體與氣體在管道內(nèi)的摩擦阻力存在差異，在設(shè)計時就需要注意此因素造成管路內(nèi)氣體竄流以及氣液分層流動問題的發(fā)生，尤其是在壓力條件不變的情況下，隨著管徑的增大問題發(fā)生的可能性越大。
Taking heptafluoropropane fire extinguishing system as an example, heptafluoropropane is transported in the form of compressed gas in the pipeline. Because there are differences in the friction resistance between liquid and gas in the pipeline, it is necessary to pay attention to the occurrence of gas channeling and gas-liquid stratified flow in the pipeline caused by this factor during design. Especially when the pressure conditions remain unchanged, the problem is more likely to occur with the increase of pipe diameter.
同時，統(tǒng)一防護區(qū)內(nèi)的不同噴嘴，如果不按照統(tǒng)一滅火設(shè)計體積分?jǐn)?shù)以及噴放時間來設(shè)計，就會導(dǎo)致系統(tǒng)防護區(qū)實際滅火體積分?jǐn)?shù)在規(guī)定時間內(nèi)無法達(dá)到設(shè)計的滅火體積分?jǐn)?shù)。
At the same time, if different nozzles in the unified protection zone are not designed according to the unified fire extinguishing design volume fraction and spraying time, the actual fire extinguishing volume fraction in the system protection zone will not reach the designed fire extinguishing volume fraction within the specified time.
進行設(shè)計時須要強調(diào)此方面的控制，保證各項參數(shù)的科學(xué)性，應(yīng)結(jié)合實際情況對噴嘴特性參數(shù)以及主要部件當(dāng)量長度值進行驗證，提高設(shè)計方案的科學(xué)性與可靠性。
During the design, it is necessary to emphasize the control of this aspect to ensure the scientificity of all parameters. The nozzle characteristic parameters and the equivalent length of main components should be verified according to the actual situation to improve the scientificity and reliability of the design scheme.
三、氣瓶設(shè)計
3、 Gas cylinder design
氣瓶是氣體滅火系統(tǒng)的存儲設(shè)備，具有存儲壓力高、使用數(shù)量大以及安裝密度大等特點，只有前期做好綜合性規(guī)劃設(shè)計，才能夠保證后期滅火系統(tǒng)的正常運行。
The gas cylinder is the storage equipment of the gas fire extinguishing system. It has the characteristics of high storage pressure, large number of use and large installation density. Only by making comprehensive planning and design in the early stage can the normal operation of the fire extinguishing system in the later stage be guaranteed.
