避(bi)難硐室供氧系(xi)統<!--?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /-->

 避難硐室(shi)供氧(yang)系統產品介(jie)紹

煤礦(kuang)六(liu)大系統(tong)(tong)(tong)(tong)(tong)之一的避(bi)難(nan)(nan)(nan)硐(dong)(dong)室(shi)系統(tong)(tong)(tong)(tong)(tong)，是煤礦(kuang)建設(she)必須配(pei)備的系統(tong)(tong)(tong)(tong)(tong)之一。避(bi)難(nan)(nan)(nan)硐(dong)(dong)室(shi)系統(tong)(tong)(tong)(tong)(tong)主要包括：礦(kuang)用避(bi)難(nan)(nan)(nan)硐(dong)(dong)室(shi)隔離(li)門，避(bi)難(nan)(nan)(nan)硐(dong)(dong)室(shi)供氧(yang)系統(tong)(tong)(tong)(tong)(tong)，避(bi)難(nan)(nan)(nan)硐(dong)(dong)室(shi)壓風系統(tong)(tong)(tong)(tong)(tong)，避(bi)難(nan)(nan)(nan)硐(dong)(dong)室(shi)氣幕(mu)噴淋系統(tong)(tong)(tong)(tong)(tong)，避(bi)難(nan)(nan)(nan)硐(dong)(dong)室(shi)供電(dian)系統(tong)(tong)(tong)(tong)(tong)，避(bi)難(nan)(nan)(nan)硐(dong)(dong)室(shi)空氣制冷系統(tong)(tong)(tong)(tong)(tong)。

壓風供(gong)氧系統(tong)壓風系統(tong)供(gong)氧裝(zhuang)置(zhi)利用硐室前預埋的(de)壓風管路(lu)作為氣(qi)源，經過(guo)閥門后先(xian)進(jin)入過(guo)渡艙內設置(zhi)的(de)水、灰塵(chen)、油的(de)三級過(guo)濾，然(ran)后經過(guo)預先(xian)設置(zhi)的(de)減壓器、、管路(lu)進(jin)入氣(qi)體(ti)輸出(chu)端，從而轉(zhuan)到每人手中的(de)呼吸面罩中，為避(bi)難所(suo)內避(bi)險人員提供(gong)更加新鮮、舒適的(de)空氣(qi)。

避難硐(dong)室供(gong)氧系統的(de)技(ji)術(shu)參數

人均供風量≥0.3m3/min；

避(bi)難所內氧氣濃度18.5～22.0%；

減壓器入(ru)口壓力≥0.8MPa、

出口壓力0～0.6 MPa（可調(diao)節(jie)）、

輸出流量(liang)不小(xiao)于36 m3/min；

目(mu)前，國內已經有多家救(jiu)生(sheng)(sheng)艙(cang)生(sheng)(sheng)產企業(ye)使用了這套自(zi)動(dong)控制(zhi)(zhi)系統，實踐證明(ming)，該(gai)系統工作穩(wen)定可靠(kao)，控制(zhi)(zhi)，反(fan)響良好。通過(guo)實際測試，我們(men)也獲得了另一個重(zhong)要參數，即呆在救(jiu)生(sheng)(sheng)艙(cang)的人，平(ping)均(jun)耗氧量為0.35-0.4/min。
