全自動過濾器
未經過(guo)(guo)濾(lv)(lv)的水通過(guo)(guo)多點布(bu)水器(qi)均勻布(bu)水，水以層(ceng)(ceng)流(liu)(liu)狀態通過(guo)(guo)過(guo)(guo)濾(lv)(lv)器(qi)內的介(jie)質(zhi)層(ceng)(ceng)。當水流(liu)(liu)經過(guo)(guo)介(jie)質(zhi)層(ceng)(ceng)時(shi)，介(jie)質(zhi)被截留在介(jie)質(zhi)層(ceng)(ceng)內。過(guo)(guo)濾(lv)(lv)器(qi)底(di)部有多個(ge)獨(du)特的縫隙集水棒，將(jiang)過(guo)(guo)濾(lv)(lv)后的水均勻地收集并流(liu)(liu)出，可以使過(guo)(guo)濾(lv)(lv)器(qi)在高流(liu)(liu)速下過(guo)(guo)濾(lv)(lv)，仍可達到較好過(guo)(guo)濾(lv)(lv)的效果(guo)。
隨著雜質(zhi)在介(jie)(jie)質(zhi)層中(zhong)不(bu)(bu)斷聚集，壓(ya)(ya)頭損失(shi)將不(bu)(bu)斷增大。當進、出水(shui)(shui)壓(ya)(ya)頭損失(shi)達(da)到(dao)(dao)設定(ding)值(zhi)時，系統將自動轉換成反(fan)(fan)(fan)(fan)洗(xi)(xi)(xi)狀(zhuang)態(tai)，以清洗(xi)(xi)(xi)聚集起來的雜質(zhi)，本源(yuan)反(fan)(fan)(fan)(fan)洗(xi)(xi)(xi)（即用(yong)(yong)過(guo)(guo)(guo)濾后(hou)的清水(shui)(shui)），反(fan)(fan)(fan)(fan)洗(xi)(xi)(xi)時，過(guo)(guo)(guo)濾仍然繼續，只是其中(zhong)要進行(xing)反(fan)(fan)(fan)(fan)洗(xi)(xi)(xi)的罐體不(bu)(bu)進行(xing)過(guo)(guo)(guo)濾，系統中(zhong)其他(ta)罐體仍在過(guo)(guo)(guo)濾。過(guo)(guo)(guo)濾過(guo)(guo)(guo)的清潔水(shui)(shui)部分(fen)用(yong)(yong)來反(fan)(fan)(fan)(fan)洗(xi)(xi)(xi)罐體，其余(yu)仍送到(dao)(dao)用(yong)(yong)水(shui)(shui)點。反(fan)(fan)(fan)(fan)沖(chong)洗(xi)(xi)(xi)排(pai)水(shui)(shui)則通過(guo)(guo)(guo)反(fan)(fan)(fan)(fan)洗(xi)(xi)(xi)排(pai)水(shui)(shui)口被排(pai)出。在TLD過(guo)(guo)(guo)濾系統中(zhong)，特殊(shu)設計(ji)的集水(shui)(shui)器使介(jie)(jie)質(zhi)層在反(fan)(fan)(fan)(fan)沖(chong)洗(xi)(xi)(xi)狀(zhuang)態(tai)形成內(nei)環流。填(tian)料之間(jian)互(hu)相搓(cuo)洗(xi)(xi)(xi)，最大限度(du)的提高反(fan)(fan)(fan)(fan)沖(chong)洗(xi)(xi)(xi)效率，減少所(suo)需的反(fan)(fan)(fan)(fan)洗(xi)(xi)(xi)水(shui)(shui)。當一個罐體反(fan)(fan)(fan)(fan)洗(xi)(xi)(xi)2-3分(fen)鐘時，反(fan)(fan)(fan)(fan)沖(chong)洗(xi)(xi)(xi)結束又恢復到(dao)(dao)過(guo)(guo)(guo)濾狀(zhuang)態(tai)，下(xia)一個過(guo)(guo)(guo)濾罐則準備進入反(fan)(fan)(fan)(fan)沖(chong)洗(xi)(xi)(xi)狀(zhuang)態(tai)。
