一、結構特點及用途

　　膜(mo)片(pian)(pian)(pian)(pian)式微孔(kong)曝(pu)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)器主(zhu)要由(you)(you)曝(pu)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)底座(zuo)、上螺(luo)旋壓蓋、空(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)均(jun)流(liu)(liu)板(ban)、合(he)(he)成(cheng)(cheng)橡(xiang)膠(jiao)膜(mo)片(pian)(pian)(pian)(pian)等組成(cheng)(cheng)，合(he)(he)成(cheng)(cheng)橡(xiang)膠(jiao)膜(mo)片(pian)(pian)(pian)(pian)上開(kai)(kai)有(you)2100—2500個按一定(ding)規則排列的(de)開(kai)(kai)閉(bi)式孔(kong)眼(yan)(yan)，充氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)時(shi)，空(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)通過布氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)管道，空(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)均(jun)流(liu)(liu)板(ban)均(jun)勻(yun)進入橡(xiang)膠(jiao)膜(mo)片(pian)(pian)(pian)(pian)之間(jian)，在空(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)壓力(li)作用下，使膜(mo)片(pian)(pian)(pian)(pian)微微鼓起，孔(kong)眼(yan)(yan)張開(kai)(kai)，達到布氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)擴散的(de)目的(de)。停(ting)止供氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)時(shi)，由(you)(you)于(yu)膜(mo)片(pian)(pian)(pian)(pian)和空(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)均(jun)流(liu)(liu)板(ban)之間(jian)壓力(li)漸(jian)漸(jian)下降，使孔(kong)眼(yan)(yan)逐漸(jian)閉(bi)合(he)(he)，當壓力(li)全部消(xiao)失后，由(you)(you)于(yu)水壓作用和膜(mo)片(pian)(pian)(pian)(pian)本身(shen)(shen)的(de)回彈作用，將膜(mo)片(pian)(pian)(pian)(pian)壓實于(yu)空(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)均(jun)流(liu)(liu)板(ban)上，鑒于(yu)上述(shu)構(gou)造以及膜(mo)片(pian)(pian)(pian)(pian)本身(shen)(shen)的(de)良好(hao)彈性(xing)(xing)，曝(pu)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)池中的(de)混合(he)(he)液不(bu)可能倒灌，因(yin)此，不(bu)會(hui)沾污孔(kong)眼(yan)(yan)。另一方(fang)面，當孔(kong)眼(yan)(yan)開(kai)(kai)啟時(shi)，由(you)(you)于(yu)橡(xiang)膠(jiao)的(de)彈性(xing)(xing)作用，空(kong)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)中所(suo)含的(de)少量(liang)塵埃，也不(bu)會(hui)造成(cheng)(cheng)曝(pu)氣(qi)(qi)(qi)(qi)(qi)(qi)(qi)器的(de)孔(kong)隙堵塞。

　　該曝氣器具有耐腐蝕、布(bu)氣均勻(yun)、微孔可變不堵塞、氧利用(yong)率和動力效率高等特點。應(ying)用(yong)于市政(zheng)及工業廢水(shui)中曝氣及生化處理工程中。

二、技術指標

三、布置、安裝

1、曝氣器(qi)均勻布(bu)置于曝氣池(chi)底(di)，其表面距池(chi)底(di)約200-300mm，間距按設計要求均勻布(bu)置。

2、進氣管的設(she)置應(ying)考(kao)慮壓力平衡(heng)，每組支(zhi)管應(ying)設(she)置閥門，便于調(diao)節空氣量，并在支(zhi)管末端設(she)置氣壓排水(shui)(shui)管，以排除因安裝(zhuang)調(diao)試或停機時流入管內的積水(shui)(shui)。
