三、工作原理(li)

一體化自(zi)動反沖凈水(shui)器(qi)由快速斜管沉淀器(qi)和(he)重力式無法過濾器(qi)兩部分(fen)有(you)機組(zu)合在一起，其(qi)工作原理及技(ji)術特性如下：

(一) 快速斜管沉淀(dian)器

快(kuai)速斜(xie)(xie)管(guan)沉(chen)淀(dian)(dian)(dian)器(qi)(qi)(qi)將傳統的平流(liu)式沉(chen)淀(dian)(dian)(dian)器(qi)(qi)(qi)進(jin)(jin)行改(gai)進(jin)(jin)，在(zai)沉(chen)淀(dian)(dian)(dian)器(qi)(qi)(qi)內設置(zhi)了(le)(le)斜(xie)(xie)管(guan)，增加(jia)了(le)(le)沉(chen)淀(dian)(dian)(dian)面(mian)(mian)積(ji)而(er)使同(tong)等面(mian)(mian)積(ji)的沉(chen)淀(dian)(dian)(dian)器(qi)(qi)(qi)增加(jia)了(le)(le)出水(shui)(shui)量，設備效(xiao)率得到大大提(ti)高，同(tong)時在(zai)處理(li)相同(tong)水(shui)(shui)量的前提(ti)下(xia)，設備面(mian)(mian)積(ji)大大減少而(er)節省(sheng)了(le)(le)投資。在(zai)設計上選用約(yue)30mm左(zuo)右的斜(xie)(xie)管(guan)管(guan)徑和(he)間距(ju)，水(shui)(shui)利條件得到明顯的改(gai)善(shan)，水(shui)(shui)流(liu)處于層(ceng)流(liu)狀態、顆粒(li)沉(chen)降(jiang)(jiang)(jiang)不(bu)受水(shui)(shui)流(liu)干擾，沉(chen)淀(dian)(dian)(dian)穩定性更好、沉(chen)降(jiang)(jiang)(jiang)路程縮短(duan)和(he)沉(chen)降(jiang)(jiang)(jiang)時間更短(duan)。由于設置(zhi)了(le)(le)混(hun)凝(ning)反應(ying)區(qu)，原(yuan)水(shui)(shui)先(xian)(xian)經過混(hun)凝(ning)反應(ying)后懸浮雜質先(xian)(xian)絮凝(ning)成較大顆粒(li)再(zai)進(jin)(jin)入沉(chen)淀(dian)(dian)(dian)區(qu)，確保了(le)(le)沉(chen)淀(dian)(dian)(dian)效(xiao)果，一(yi)般情況下(xia)原(yuan)水(shui)(shui)濁度(du)(du)在(zai)1000ppm以(yi)下(xia)時，沉(chen)淀(dian)(dian)(dian)器(qi)(qi)(qi)出水(shui)(shui)濁度(du)(du)可(ke)小于15ppm。

(二(er)) 重力(li)式無閥過濾器

重力式無法過濾器(qi)對沉淀器(qi)出(chu)水進(jin)行深(shen)度過濾處理，采(cai)用先進(jin)的水力全自動運行方(fang)式。

過(guo)濾(lv)(lv)流(liu)程：經沉淀或澄清(qing)(qing)后的(de)清(qing)(qing)水(shui)(shui)(shui)，經配(pei)(pei)水(shui)(shui)(shui)槽和U型管進(jin)入虹吸上升管，再由頂(ding)蓋內(nei)的(de)步水(shui)(shui)(shui)檔板均勻(yun)地分配(pei)(pei)到(dao)濾(lv)(lv)料層(ceng)中，水(shui)(shui)(shui)自(zi)上而下通過(guo)濾(lv)(lv)層(ceng)進(jin)行過(guo)濾(lv)(lv)，濾(lv)(lv)后水(shui)(shui)(shui)由小阻力配(pei)(pei)水(shui)(shui)(shui)裝置進(jin)行收集后進(jin)入清(qing)(qing)水(shui)(shui)(shui)區（即出水(shui)(shui)(shui)箱）貯存，當水(shui)(shui)(shui)位上升至出水(shui)(shui)(shui)管時，濾(lv)(lv)后水(shui)(shui)(shui)自(zi)流(liu)到(dao)清(qing)(qing)水(shui)(shui)(shui)池。

反洗(xi)(xi)流(liu)程(cheng)：濾(lv)(lv)池(chi)運(yun)行(xing)初時比較清(qing)潔，隨著運(yun)行(xing)時間(jian)的(de)(de)(de)推移而濾(lv)(lv)層表面(mian)顆粒雜質逐漸(jian)增多，水(shui)(shui)頭損(sun)失(shi)也隨之增加，水(shui)(shui)位(wei)將沿(yan)(yan)著虹(hong)(hong)吸上(shang)升(sheng)(sheng)管(guan)(guan)(guan)(guan)慢慢升(sheng)(sheng)高，當水(shui)(shui)頭損(sun)失(shi)增加到(dao)一定程(cheng)度后，虹(hong)(hong)吸上(shang)升(sheng)(sheng)管(guan)(guan)(guan)(guan)中的(de)(de)(de)水(shui)(shui)位(wei)上(shang)升(sheng)(sheng)到(dao)虹(hong)(hong)吸輔助(zhu)管(guan)(guan)(guan)(guan)口(kou)并從輔助(zhu)管(guan)(guan)(guan)(guan)口(kou)急速流(liu)下(xia)(xia)，依靠水(shui)(shui)流(liu)的(de)(de)(de)挾氣和射(she)流(liu)作(zuo)用及抽氣管(guan)(guan)(guan)(guan)將虹(hong)(hong)吸管(guan)(guan)(guan)(guan)中的(de)(de)(de)空(kong)氣帶(dai)走，使虹(hong)(hong)吸管(guan)(guan)(guan)(guan)形成(cheng)真空(kong)，虹(hong)(hong)吸上(shang)升(sheng)(sheng)管(guan)(guan)(guan)(guan)中的(de)(de)(de)水(shui)(shui)就大量地越過(guo)(guo)管(guan)(guan)(guan)(guan)頂沿(yan)(yan)虹(hong)(hong)吸下(xia)(xia)降(jiang)(jiang)管(guan)(guan)(guan)(guan)落下(xia)(xia)，即開始了反沖(chong)(chong)洗(xi)(xi)過(guo)(guo)程(cheng)。清(qing)水(shui)(shui)區(qu)的(de)(de)(de)水(shui)(shui)經(jing)過(guo)(guo)連通管(guan)(guan)(guan)(guan)、集水(shui)(shui)區(qu)和配(pei)水(shui)(shui)裝(zhuang)置(zhi)(zhi)從下(xia)(xia)而上(shang)沖(chong)(chong)洗(xi)(xi)濾(lv)(lv)料層，當清(qing)水(shui)(shui)區(qu)的(de)(de)(de)水(shui)(shui)位(wei)下(xia)(xia)降(jiang)(jiang)到(dao)虹(hong)(hong)吸破壞裝(zhuang)置(zhi)(zhi)時（約(yue)5min左右），虹(hong)(hong)吸被(bei)破壞而沖(chong)(chong)洗(xi)(xi)過(guo)(guo)程(cheng)結束，過(guo)(guo)濾(lv)(lv)又重新開始。本裝(zhuang)置(zhi)(zhi)省去了傳統的(de)(de)(de)反沖(chong)(chong)洗(xi)(xi)水(shui)(shui)泵，同時不需(xu)要抽取清(qing)水(shui)(shui)池(chi)的(de)(de)(de)

清水作(zuo)(zuo)反(fan)沖(chong)洗用水，整個系統的(de)(de)管(guan)(guan)(guan)路配置(zhi)非常簡單(dan)，大(da)大(da)地(di)減(jian)輕了操(cao)作(zuo)(zuo)管(guan)(guan)(guan)理強度與設(she)備投資(zi)。由于反(fan)沖(chong)洗是根(gen)據(ju)濾層的(de)(de)堵塞程(cheng)度而自動進行的(de)(de)，減(jian)少了人為操(cao)作(zuo)(zuo)的(de)(de)失誤(wu)，整套裝(zhuang)置(zhi)可在無(wu)人操(cao)作(zuo)(zuo)的(de)(de)狀態(tai)下(xia)進行。同時，我公司根(gen)據(ju)實際經驗，設(she)置(zhi)了強制反(fan)洗裝(zhuang)置(zhi)，在虹(hong)(hong)吸輔助管(guan)(guan)(guan)上增加了一根(gen)自來水管(guan)(guan)(guan)，當(dang)出水水質突然發生較大(da)變化(hua)時，打開閥門，依靠水流的(de)(de)挾氣(qi)和(he)射流作(zuo)(zuo)用及抽氣(qi)管(guan)(guan)(guan)將虹(hong)(hong)吸管(guan)(guan)(guan)中(zhong)的(de)(de)空(kong)(kong)氣(qi)帶走，使虹(hong)(hong)吸管(guan)(guan)(guan)形成真空(kong)(kong)，虹(hong)(hong)吸上升(sheng)管(guan)(guan)(guan)中(zhong)的(de)(de)水就(jiu)大(da)量地(di)越(yue)過(guo)管(guan)(guan)(guan)頂沿虹(hong)(hong)吸下(xia)降管(guan)(guan)(guan)落下(xia)，強制開始反(fan)沖(chong)洗過(guo)程(cheng)。
