火災(zāi)特征:
Fire characteristics:
古建筑多為木結(jié)構(gòu)，遇火后容易產(chǎn)生陰燃，是A類火災(zāi)中難發(fā)生的火災(zāi)。工廠、倉(cāng)庫(kù)(尤其是寺廟)里的古建筑，大部分都鋪著木瓦，木瓦頂端，形狀各異。寺廟和道觀等相當(dāng)數(shù)量的古建筑位于偏遠(yuǎn)的山區(qū)和村莊。由于交通不利，年久失修，缺少香火，政府文物管理部門管不了，無(wú)人看管，或者只是無(wú)人看管，不使用。甚其中一些古建筑被列為和省級(jí)文物保護(hù)單位，具有很大的建筑藝術(shù)和文物保護(hù)價(jià)值。其中一些古建筑甚常年鎖著門，無(wú)人看管。只要發(fā)生火災(zāi)，后果不堪設(shè)想。
Most ancient buildings are made of wooden structures, which are prone to smoldering when exposed to fire, making them a rare occurrence in Class A fires. Most of the ancient buildings in factories and warehouses (especially temples) are covered with wooden tiles, with different shapes at the top. A considerable number of ancient buildings such as temples and Taoist temples are located in remote mountainous areas and villages. Due to poor transportation, prolonged disrepair, and lack of incense, the government's cultural relics management department is unable to manage it, leaving it unattended or simply not in use. Even some of these ancient buildings are listed as national and provincial-level cultural relics protection units, with great value in architectural art and cultural relics protection. Some of these ancient buildings even have locked doors all year round and are left unattended. As long as a fire occurs, the consequences are unimaginable.
超細(xì)干粉滅火劑對(duì)工廠、倉(cāng)庫(kù)、古建筑(主要是寺廟)火災(zāi)的適用性。超細(xì)干粉滅火裝置適用性能
Applicability of ultrafine dry powder fire extinguishing agents for fires in factories, warehouses, and ancient buildings (mainly temples). Applicable performance of ultrafine dry powder fire extinguishing equipment
以磷酸銨鹽為代表的超細(xì)干粉滅火劑ABC干粉滅火劑是古老的滅火劑之一，是當(dāng)前消防產(chǎn)品的主力軍；滅火機(jī)理以化學(xué)滅火為主，物理滅火為輔，應(yīng)用于全淹沒固定式滅火系統(tǒng)，低溫性能好，效果好。的技術(shù)在于超細(xì)粉體的制備，其優(yōu)異的性能是:
The ultra-fine dry powder fire extinguishing agent ABC, represented by ammonium phosphate, is one of the ancient fire extinguishing agents and the main force of current fire protection products; The fire extinguishing mechanism is mainly based on chemical fire extinguishing, supplemented by physical fire extinguishing. It is applied to fully submerged fixed fire extinguishing systems with good low-temperature performance and effectiveness. The advanced technology lies in the preparation of ultrafine powders, whose excellent performance is:
1.它具有很好的滅火速度和效率，對(duì)一般固體物質(zhì)的表面燃燒(陰燃)有很好的滅火效果。超細(xì)干粉晶體粉末與燃燒表面接觸時(shí)，發(fā)生一系列化學(xué)反應(yīng)，在固體表面高溫作用下熔化，形成玻璃狀覆蓋層，將固體表面與周圍空氣隔開，從而使燃燒窒息。
1. It has excellent fire extinguishing speed and efficiency, and has a good fire extinguishing effect on the surface combustion (smoldering) of general solid substances. When ultrafine dry powder crystals come into contact with the combustion surface, a series of chemical reactions occur, which melt under the high-temperature action of the solid surface, forming a glassy covering layer that separates the solid surface from the surrounding air, thereby suffocating combustion.
2.超細(xì)干粉滅火劑具有零大氣臭氧層消耗潛能(ODP)和零溫室效應(yīng)潛能(GWP)，對(duì)人體皮膚無(wú)刺激，對(duì)防護(hù)物無(wú)腐蝕，無(wú)害。滅火后殘留物易于清理。
2. Ultra fine dry powder fire extinguishing agents have zero ozone depletion potential (ODP) and zero greenhouse effect potential (GWP), are non irritating to human skin, non corrosive to protective materials, and are non-toxic and harmless. The residue after extinguishing is easy to clean.
3.屏蔽冷卻熱輻射功能:超細(xì)干粉滅火時(shí)，濃云狀粉末與火焰混合，分解吸熱反應(yīng)可吸收火焰部分熱量。這些分解反應(yīng)產(chǎn)生的一些惰性氣體，如二氧化碳和水蒸氣，可以稀釋燃燒區(qū)的氧氣濃度，從而減弱火災(zāi)的燃燒反應(yīng)。
3. Shielding cooling heat radiation function: When ultrafine dry powder is used for fire extinguishing, the concentrated cloud like powder is mixed with the flame, and the decomposition endothermic reaction can absorb some heat from the flame. The inert gases generated by these decomposition reactions, such as carbon dioxide and water vapor, can dilute the oxygen concentration in the combustion zone, thereby weakening the combustion reaction in a fire.
4.滅火效率高:單位體積滅火效率是哈龍滅火劑的2-3倍，是普通ABC干粉滅火劑的6-10倍，是七氟丙烷滅火劑的10-12倍。
4. High fire extinguishing efficiency: The fire extinguishing efficiency per unit volume is 2-3 times that of halon fire extinguishing agent, 6-10 times that of ordinary ABC dry powder fire extinguishing agent, and 10-12 times that of heptafluoropropane fire extinguishing agent.
超細(xì)干粉滅火劑不僅適用于相對(duì)封閉空間的全淹沒，也適用于室外火災(zāi)危險(xiǎn)場(chǎng)所的局部應(yīng)用。特別是對(duì)于A類火災(zāi)和深層次火災(zāi)，在工廠、倉(cāng)庫(kù)、古建筑(尤其是寺廟)使用超細(xì)干粉滅火劑為有效。
Ultra fine dry powder fire extinguishing agents are not only suitable for total flooding in relatively enclosed spaces, but also for local applications in outdoor fire hazard areas. Especially for Class A fires and deep level fires, the use of ultrafine dry powder fire extinguishing agents is effective in factories, warehouses, and ancient buildings (especially temples).
建筑、倉(cāng)庫(kù)(特別是寺廟)無(wú)管網(wǎng)超細(xì)干粉自動(dòng)滅火裝置的設(shè)計(jì)與應(yīng)用。
Design and application of ultra-fine dry powder automatic fire extinguishing devices without pipeline network in buildings and warehouses (especially temples).
超細(xì)干粉自動(dòng)滅火裝置的應(yīng)用是一項(xiàng)非常成熟的技術(shù)。該裝置采用氮?dú)怛?qū)動(dòng)，無(wú)聲常壓，可實(shí)現(xiàn)局部保護(hù)和類氣全淹沒保護(hù)。啟動(dòng)方式有電控、溫控、超導(dǎo)啟動(dòng)，單個(gè)裝置即可使用，多個(gè)裝置可以聯(lián)動(dòng)形成一個(gè)無(wú)管網(wǎng)的滅火系統(tǒng)。
The application of ultrafine dry powder automatic fire extinguishing devices is a very mature technology. This device is driven by nitrogen gas, silent and atmospheric pressure, and can achieve local protection and gas like total flooding protection. The starting methods include electric control, temperature control, and superconducting starting. A single device can be used, and multiple devices can be linked to form a non pipe network fire extinguishing system.
