( 5) 自動(dong)排(pai)泥與(yu)自動(dong)反(fan)沖洗。

①自動排(pai)(pai)泥(ni)(ni): 在(zai)沉淀(dian)池的外側有大計時斗, 斗上裝有水嘴和浮(fu)球(qiu)開關。當水嘴將大計時斗裝滿時, 浮(fu)球(qiu)開關打(da)開, 迅(xun)速(su)進水, 促使斗內小虹(hong)(hong)(hong)(hong)吸(xi)(xi)管(guan)(guan)(guan)產(chan)生虹(hong)(hong)(hong)(hong)吸(xi)(xi)。抽去排(pai)(pai)泥(ni)(ni)虹(hong)(hong)(hong)(hong)吸(xi)(xi)管(guan)(guan)(guan)內的空(kong)氣而產(chan)生排(pai)(pai)泥(ni)(ni)虹(hong)(hong)(hong)(hong)吸(xi)(xi), 沉淀(dian)室底的污泥(ni)(ni)便從(cong)排(pai)(pai)泥(ni)(ni)多(duo)孔管(guan)(guan)(guan)進入, 經排(pai)(pai)泥(ni)(ni)虹(hong)(hong)(hong)(hong)吸(xi)(xi)管(guan)(guan)(guan)排(pai)(pai)出。當水被(bei)吸(xi)(xi)完后(hou), 空(kong)氣便從(cong)小虹(hong)(hong)(hong)(hong)吸(xi)(xi)管(guan)(guan)(guan)進入排(pai)(pai)泥(ni)(ni)虹(hong)(hong)(hong)(hong)吸(xi)(xi)管(guan)(guan)(guan)而破壞排(pai)(pai)泥(ni)(ni)虹(hong)(hong)(hong)(hong)吸(xi)(xi), 則(ze)排(pai)(pai)泥(ni)(ni)停止。

②排泥(ni)(ni)周(zhou)期與排泥(ni)(ni)時(shi)間的(de)控(kong)(kong)制(zhi): 調節水嘴裝(zhuang)滿大計時(shi)斗的(de)周(zhou)期控(kong)(kong)制(zhi)排泥(ni)(ni)周(zhou)期, 調節小虹吸管(guan)上閥門吸掉斗內存水的(de)時(shi)間控(kong)(kong)制(zhi)排泥(ni)(ni)時(shi)間。

③自(zi)動反(fan)沖(chong)洗(xi): 隨著過(guo)濾(lv)時(shi)間(jian)的(de)增長, 濾(lv)層內(nei)的(de)阻(zu)力逐漸增加, 反(fan)沖(chong)洗(xi)虹吸(xi)上(shang)(shang)升管內(nei)的(de)水位便隨之上(shang)(shang)升。當水位上(shang)(shang)升到(dao)虹吸(xi)輔助口(kou)( 最(zui)高點) 時(shi), 小虹吸(xi)管開始虹吸(xi), 抽去大(da)虹吸(xi)管中(zhong)(zhong)的(de)空氣而產生(sheng)反(fan)沖(chong)洗(xi)虹吸(xi)。將需反(fan)沖(chong)洗(xi)過(guo)濾(lv)室(shi)中(zhong)(zhong)的(de)水吸(xi)走, 其他(ta)各(ge)池的(de)濾(lv)后水從室(shi)底(di)流來補充, 對(dui)過(guo)濾(lv)室(shi)的(de)濾(lv)料進行(xing)反(fan)沖(chong)洗(xi)。

④反(fan)(fan)(fan)沖(chong)(chong)洗(xi)停止(zhi): 當(dang)虹吸(xi)上升(sheng)管中水(shui)位到達虹吸(xi)輔助口時(shi), 小計時(shi)斗(dou)上的引水(shui)管自(zi)動(dong)向斗(dou)內(nei)裝水(shui), 產(chan)生反(fan)(fan)(fan)沖(chong)(chong)洗(xi)虹吸(xi)后(hou), 引水(shui)自(zi)動(dong)停止(zhi)。斗(dou)內(nei)的水(shui)從斗(dou)底的水(shui)嘴排出, 當(dang)排盡斗(dou)內(nei)存水(shui)時(shi), 空(kong)氣從虹吸(xi)破壞管內(nei)進入反(fan)(fan)(fan)沖(chong)(chong)洗(xi)虹吸(xi)系統而破壞反(fan)(fan)(fan)洗(xi)虹吸(xi), 反(fan)(fan)(fan)沖(chong)(chong)洗(xi)停止(zhi)。

⑤反沖(chong)洗(xi)(xi)(xi)歷(li)時和沖(chong)洗(xi)(xi)(xi)強(qiang)(qiang)度調(diao)節(jie): 沖(chong)洗(xi)(xi)(xi)歷(li)時通過調(diao)節(jie)小(xiao)計時斗水嘴的開啟度來實現。沖(chong)洗(xi)(xi)(xi)強(qiang)(qiang)度靠(kao)調(diao)節(jie)虹(hong)吸下降管口的強(qiang)(qiang)度調(diao)節(jie)器來實現, 將(jiang)閘板上提(ti)反沖(chong)洗(xi)(xi)(xi)強(qiang)(qiang)度大(da), 反之強(qiang)(qiang)度小(xiao)。流量根據排水溝中的可(ke)流動斷(duan)面來計算(suan)。

2.一體(ti)化凈水(shui)器(qi)處(chu)理前后水(shui)質(zhi)比較

西山煤(mei)電集團古交給排水(shui)(shui)公(gong)司(si)凈化水(shui)(shui)廠, 自(zi)2004 年10 月一體化凈水(shui)(shui)器正式投產(chan)運(yun)行以后, 運(yun)行狀(zhuang)況(kuang)良好。pH 由7.4 降(jiang)為7.3, 如表1 數據(ju)所(suo)示, 出(chu)水(shui)(shui)滿足屯蘭礦井下生產(chan)水(shui)(shui)質標準(zhun)的要求。

3.結語

一體化凈水(shui)(shui)器反應區柵(zha)條絮凝效果理想, 生成的礬花大且(qie)密實, 易于沉(chen)淀(dian)。采用錐底(di)濃(nong)縮多孔環(huan)管(guan)的水(shui)(shui)力自(zi)控排泥, 排泥徹底(di), 自(zi)耗(hao)水(shui)(shui)量少。

無清水(shui)(shui)箱(xiang)無閥過濾(lv)室徹底解決了(le)因“挾氣運行”帶來的不(bu)沖(chong)洗(xi)(xi)、假沖(chong)洗(xi)(xi)、連續沖(chong)洗(xi)(xi)和脈沖(chong)式進水(shui)(shui)以及出水(shui)(shui)水(shui)(shui)質差等問題。濾(lv)料采用雙層(ceng)均質濾(lv)料使(shi)濾(lv)層(ceng)含(han)污和截污能力增強, 過濾(lv)周期(qi)大(da)大(da)延長, 減少了(le)設(she)備(bei)的自用水(shui)(shui)量。反沖(chong)洗(xi)(xi)水(shui)(shui)頭高(gao)而(er)穩(wen)定, 可(ke)大(da)幅度調整(zheng)沖(chong)洗(xi)(xi)歷時(shi), 從而(er)克服了(le)無閥濾(lv)池反沖(chong)洗(xi)(xi)不(bu)徹底和停(ting)水(shui)(shui)時(shi)間長的缺點。

設備沖(chong)洗(xi)均(jun)為水力自(zi)控, 克服了(le)人(ren)工(gong)沖(chong)洗(xi)造(zao)成的(de)缺點。并且(qie)設備外(wai)圍系統(tong)簡單, 不需(xu)另設反沖(chong)洗(xi)泵(beng)及相關(guan)的(de)管(guan)線、電器控制(zhi)系統(tong)等。避(bi)免(mian)了(le)由于以上原因(yin)造(zao)成不穩定(ding)(ding)因(yin)素, 因(yin)而(er)自(zi)身運行具有非常(chang)好的(de)穩定(ding)(ding)性及可靠性。

由(you)于設備實現了水力自控(kong)(kong)排泥與反沖洗(xi), 在調(diao)試(shi)投入運(yun)行后基本上不(bu)用管理(li)。大(da)量減輕了體力勞動。反沖洗(xi)不(bu)用動力, 降低了水處理(li)成本, 解決了最(zui)關鍵、最(zui)復雜的部(bu)分自控(kong)(kong)系統(tong)。而(er)且水力自控(kong)(kong)比電控(kong)(kong)經久耐用, 不(bu)出故障。

在礦井水處(chu)(chu)(chu)理過(guo)程中(zhong), 采(cai)用集絮凝(ning)反應、沉淀、過(guo)濾于一體的凈水設備(bei), 具有較(jiao)好的水處(chu)(chu)(chu)理效果及較(jiao)滿意(yi)的實(shi)際運用價值(zhi), 同(tong)時能減少占(zhan)地面積, 節省(sheng)投資, 是礦井水處(chu)(chu)(chu)理理想(xiang)、經濟的水處(chu)(chu)(chu)理池(chi)型之一, 有著廣(guang)闊的發展前景(jing)
