二氧化碳?xì)怏w滅火后沒(méi)有殘留物，不會(huì)對(duì)保護(hù)物品造成損傷，不會(huì)破壞大氣臭氧層，而且它的來(lái)源廣泛、低廉，廣泛應(yīng)用于檔案等珍貴資料房、變配電室等封閉空間的保護(hù)。按照儲(chǔ)存壓力，可以分為高壓二氧化碳滅火系統(tǒng)和低壓二氧化碳滅火系統(tǒng)。下面來(lái)簡(jiǎn)單了解下兩者的區(qū)別吧。
Carbon dioxide gas has no residue after fire extinguishing, will not cause damage to protective articles, and will not destroy the atmospheric ozone layer. Moreover, it has a wide range of sources and low prices, and is widely used for the protection of precious reference rooms such as archives, power transformation and distribution rooms and other enclosed spaces. According to the storage pressure, it can be divided into high-pressure carbon dioxide fire extinguishing system and low-pressure carbon dioxide fire extinguishing system. Let's briefly understand the difference between the two.
高壓二氧化碳滅火系統(tǒng)儲(chǔ)存壓力為5.7Mpa,工作溫度范圍為0～50℃，滅火劑儲(chǔ)存容積為70L，既能用于全淹沒(méi)保護(hù)又能用于局部淹沒(méi)保護(hù)。高壓系統(tǒng)的二氧化碳滅火劑儲(chǔ)存無(wú)需配置制冷保溫系統(tǒng)，沒(méi)有日常運(yùn)行能耗，管理方便、維修也比較簡(jiǎn)單;較高的儲(chǔ)存壓力使得滅火劑有較大的輸送距離，有效提高了系統(tǒng)的保護(hù)范圍。
The storage pressure of the high-pressure carbon dioxide fire extinguishing system is 5.7mpa, the working temperature range is 0 ~ 50 ℃, and the storage volume of the extinguishing agent is 70L, which can be used for both full flooding protection and local flooding protection. The storage of carbon dioxide extinguishing agent in the high-pressure system does not need to be equipped with a refrigeration and insulation system, so there is no daily operation energy consumption, convenient management and simple maintenance; The higher storage pressure makes the fire extinguishing agent have a larger transmission distance, which effectively improves the protection range of the system.
低壓二氧化碳滅火系統(tǒng)儲(chǔ)存壓力為2.1Mpa,工作溫度范圍為-20～-18℃，一般只用于全淹沒(méi)保護(hù)。低壓系統(tǒng)雖然能儲(chǔ)存大量滅火劑,但儲(chǔ)存需要配置制冷保溫系統(tǒng)，有日常運(yùn)行能耗，管理不便、維護(hù)復(fù)雜。
The storage pressure of low-pressure carbon dioxide fire extinguishing system is 2.1MPa, and the working temperature range is -20 ~ -18 ℃. Generally, it is only used for total flooding protection. Although the low-pressure system can store a large amount of extinguishing agent, it needs to be equipped with refrigeration and insulation system for storage, which has daily operation energy consumption, inconvenient management and complex maintenance.
此外高壓二氧化碳滅火系統(tǒng)滅火原理為窒息滅火，并有少量的冷卻降溫作用。與其他氣體滅火系統(tǒng)相比，高壓二氧化碳滅火系統(tǒng)不僅能進(jìn)行全淹沒(méi)滅火應(yīng)用方式滅火，還能進(jìn)行局部應(yīng)用滅火設(shè)計(jì)，應(yīng)用靈活，對(duì)于像軋機(jī)、印刷機(jī)、烘干設(shè)備、汽車廠噴漆生產(chǎn)線等容易失火的局部部位進(jìn)行保護(hù)。
In addition, the fire extinguishing principle of the high-pressure carbon dioxide fire extinguishing system is asphyxiation and has a small amount of cooling effect. Compared with other gas fire-extinguishing systems, the high-pressure carbon dioxide fire-extinguishing system can not only extinguish the fire by means of total flooding, but also carry out local application fire-extinguishing design. It can be applied flexibly to protect local parts prone to fire, such as rolling mills, printing presses, drying equipment, automobile factory paint production lines, etc.
川消高壓二氧化碳滅火系統(tǒng)有自動(dòng)啟動(dòng)、人工電氣啟動(dòng)、緊急停止和機(jī)械應(yīng)急手動(dòng)操作四種啟動(dòng)方式，當(dāng)應(yīng)用于有人值守的場(chǎng)所時(shí)可不設(shè)置自動(dòng)啟動(dòng)。自動(dòng)啟動(dòng)將氣體滅火報(bào)警控制器上的控制方式選擇鍵撥到“自動(dòng)”位置時(shí)，滅火系統(tǒng)處于自動(dòng)控制狀態(tài)。
Chuanxiao high pressure carbon dioxide fire extinguishing system has four startup modes: automatic startup, manual electrical startup, emergency stop and mechanical emergency manual operation. When it is used in attended places, automatic startup may not be set. Automatic startup when the control mode selection key on the gas fire extinguishing alarm controller is turned to the "automatic" position, the fire extinguishing system is in the automatic control state.
當(dāng)防護(hù)區(qū)發(fā)生火情，火災(zāi)探測(cè)器發(fā)出火災(zāi)信號(hào)，火災(zāi)報(bào)警控制器即發(fā)出聲、光報(bào)警信號(hào)，同時(shí)發(fā)出聯(lián)動(dòng)指令，關(guān)閉連鎖設(shè)備，經(jīng)過(guò)一定延時(shí)時(shí)間(0～30秒可調(diào)，此時(shí)間內(nèi)防護(hù)區(qū)人員必須全部撤離)，控制器向滅火設(shè)備發(fā)出滅火指令。
When a fire occurs in the protection area, the fire detector will send a fire signal, and the fire alarm controller will send an audible and visual alarm signal. At the same time, it will send a linkage command to close the interlocking equipment. After a certain delay time (0 ~ 30 seconds can be adjusted, and all personnel in the protection area must evacuate within this time), the controller will send a fire-fighting command to the fire-fighting equipment.
電磁型驅(qū)動(dòng)裝置動(dòng)作打開(kāi)驅(qū)動(dòng)氣體瓶組容器閥釋放驅(qū)動(dòng)氣體，驅(qū)動(dòng)氣體順序打開(kāi)相應(yīng)的選擇閥和滅火劑瓶組容器閥，釋放滅火劑，實(shí)施滅火。
The electromagnetic driving device acts to open the container valve of the driving gas cylinder group to release the driving gas. The driving gas sequentially opens the corresponding selector valve and the container valve of the extinguishing agent cylinder group to release the extinguishing agent and put out the fire.
人工電氣啟動(dòng)將氣體滅火報(bào)警控制器上的控制方式選擇鍵撥到“手動(dòng)”位置時(shí)，滅火系統(tǒng)處于人工電氣控制狀態(tài)。
Manual electrical startup when the control mode selection key on the gas fire extinguishing alarm controller is turned to the "manual" position, the fire extinguishing system is in the manual electrical control state.
