目前，我國研制的首列“細(xì)水霧”地鐵車輛，在中國北車集團(tuán)大連機(jī)車車輛有限公司下線，并將上線進(jìn)行各項(xiàng)試驗(yàn)。細(xì)水霧滅火系統(tǒng)在國內(nèi)地鐵中尚屬首次應(yīng)用，這項(xiàng)地鐵滅火領(lǐng)域具有前瞻性的技術(shù)，為地鐵火災(zāi)防范提供了全新理念。
據(jù)了解，在地鐵車輛自動消防方式中，細(xì)水霧滅火方式能夠避免氣體滅火和水噴淋滅火方式的不足和弊端，無論是可靠性和安全性，還是系統(tǒng)的響應(yīng)速度和滅火的效果，都完全符合地鐵列車滅火的要求。細(xì)水霧自動滅火系統(tǒng)通過高壓和噴嘴將通過管道的水，霧化成具有高動能的毛細(xì)水珠。在火場中，毛細(xì)水珠龐大的接觸表面積能夠快速充分地吸收火源附近的能量，通過毛細(xì)水珠在火場中液態(tài)到氣態(tài)的蒸發(fā)。置換火場中的氧氣，達(dá)到使火源窒息的作用，無污染，絕對環(huán)保。同時(shí)，此系統(tǒng)具有高加速度的毛細(xì)水珠，可實(shí)現(xiàn)對火場的全淹沒，并可以用于遮擋受阻空間的火災(zāi)；此外，毛細(xì)水珠氣化所產(chǎn)生的水蒸氣還可以吸附煙塵粒子。
大空間水炮產(chǎn)品在國內(nèi)眾多體育館、會展中心、飛機(jī)場、火車站、商場、劇院、廠房、倉庫等大型大空間建筑中有了良好的應(yīng)用。
