移動(dòng)式氫復(fù)合裝置由全屏蔽消氫風(fēng)機(jī)、冷卻冷凝器、汽液分離器、催化反應(yīng)器、冷卻器和電氣控制柜等組成。除電氣控制柜外的所有設(shè)備安放在一個(gè)可以移動(dòng)的小車上。該裝置的設(shè)計(jì)、制造和檢驗(yàn)符合ASME規(guī)范中核二級(jí)的要求。儀器儀表電氣符合1E、K3的要求。
在2002年產(chǎn)品鑒定會(huì)上與會(huì)核電專家給與了“白,達(dá)到水平"的較高評(píng)價(jià),認(rèn)為該產(chǎn)品具有如下技術(shù)優(yōu)勢(shì):
①采用于式去除有害雜質(zhì)和高性能的消氫催化劑實(shí)現(xiàn)在較低溫度下的消氫,使氫復(fù)合器具有消氫效率高、能耗低、運(yùn)行安全可靠;
②采用全屏蔽渦旋消氫風(fēng)機(jī)和裝置總體布置的緊湊型設(shè)計(jì)實(shí)現(xiàn)了車載化,使氫復(fù)合器體積小重量輕、使用方便;
③采用壓力平衡原理,配合液位控制、電磁閥組和合適的控制電路實(shí)現(xiàn)了自動(dòng)排水功能,能夠保證在排水過(guò)程中放射性氣體不泄漏。
④選用磁釉真空燒結(jié)封口的U彩管狀電加熱元件,杜絕了因長(zhǎng)期存放造成的絕緣電阻降低的現(xiàn)象,提高了設(shè)備使用的可靠性。
其*可靠的工藝、新穎合理的結(jié)構(gòu)設(shè)計(jì)取得了國(guó)家,號(hào)為ZL.0,2004年獲國(guó)防科工委科技進(jìn)步二等獎(jiǎng)。
移動(dòng)式氫復(fù)合器廣泛適用于壓水堆核電站的安全殼ETY系統(tǒng)的消氫,可以作為新建核電站,包括百萬(wàn)瓦級(jí)核電站的選用對(duì)象。該產(chǎn)品已成功應(yīng)用于秦山二期、方家山一期、福清一期、紅沿河一期、寧德一期、陽(yáng)江一期、防城港一期等核電站,運(yùn)行穩(wěn)定,性能可靠,獲得用戶好評(píng)。
