膠(jiao)球(qiu)清洗裝置(zhi)技(ji)術方案
中央(yang)空(kong)調(diao)冷(leng)卻器，單(dan)個冷(leng)卻器為單(dan)流回程管(guan)路，設(she)備配(pei)套是兩臺冷(leng)卻器，冬夏季切(qie)換使(shi)用(yong)(yong)(yong)。冷(leng)卻水(shui)采用(yong)(yong)(yong)生活(huo)廢水(shui)，正常使(shi)用(yong)(yong)(yong)溫度在35-45℃時產生沼類軟垢。根據我們多年的經驗證明，采用(yong)(yong)(yong)生活(huo)廢水(shui)作為冷(leng)卻器，使(shi)用(yong)(yong)(yong)膠球(qiu)清洗是必(bi)要的。
設備的具(ju)體(ti)布置：
膠球(qiu)清(qing)洗裝(zhuang)置含兩臺(tai)收(shou)球(qiu)網（每臺(tai)冷卻器(qi)的冷卻水回水管(guan)道裝(zhuang)1臺(tai)）、1臺(tai)裝(zhuang)球(qiu)室、1臺(tai)膠球(qiu)輸送泵、2臺(tai)分(fen)匯器(qi)、1只磁性開關。
膠(jiao)(jiao)球(qiu)清洗(xi)裝(zhuang)(zhuang)(zhuang)置(zhi)的(de)布置(zhi)方位，固(gu)定膠(jiao)(jiao)球(qiu)輸送泵(beng)的(de)位置(zhi)，裝(zhuang)(zhuang)(zhuang)球(qiu)室裝(zhuang)(zhuang)(zhuang)在膠(jiao)(jiao)球(qiu)泵(beng)的(de)進口(kou)前，膠(jiao)(jiao)球(qiu)泵(beng)的(de)出口(kou)管連接在冷卻器(qi)(qi)的(de)進水口(kou)與冷卻器(qi)(qi)管殼(ke)350mm之間(jian)，裝(zhuang)(zhuang)(zhuang)球(qiu)室的(de)收球(qiu)口(kou)連接在收球(qiu)網的(de)收球(qiu)口(kou)上，便于切換。兩(liang)臺收球(qiu)網之間(jian)裝(zhuang)(zhuang)(zhuang)1臺分(fen)匯器(qi)(qi)，分(fen)匯器(qi)(qi)的(de)兩(liang)根(gen)收球(qiu)管道裝(zhuang)(zhuang)(zhuang)2只球(qiu)閥（DN100），兩(liang)根(gen)送球(qiu)管道中間(jian)同樣裝(zhuang)(zhuang)(zhuang)1臺分(fen)匯器(qi)(qi)，分(fen)匯器(qi)(qi)兩(liang)端(duan)裝(zhuang)(zhuang)(zhuang)有2臺球(qiu)閥（DN100）。
使(shi)用(yong)了(le)我廠生產的膠(jiao)球清(qing)洗裝置(zhi)在(zai)機(ji)組不停機(ji)時能(neng)對凝(ning)汽器(qi)實(shi)現在(zai)線清(qing)洗，大(da)大(da)增(zeng)加了(le)凝(ning)汽器(qi)冷卻(que)管的使(shi)用(yong)壽命，延長了(le)機(ji)組大(da)、小修周(zhou)期。
由于使(shi)用(yong)了(le)膠球清(qing)洗(xi)裝(zhuang)置(zhi)，整個凝汽器真空將有明(ming)顯的該善(shan)，按常(chang)規N50機組(zu)參數分析，綜合(he)折算(suan)機組(zu)的熱效(xiao)率可提(ti)高2.25%，供(gong)電煤耗9.66g/KW.h,年(nian)節煤3375.0噸,每噸按300元計(ji)算(suan),則每臺機組(zu)每年(nian)可節約人民幣101.250萬元。單臺膠球清(qing)洗(xi)裝(zhuang)置(zhi)全部(bu)投資（設(she)備費用(yong)、輔助材料(liao)、管道、工時等）綜合(he)費用(yong)60萬元，全部(bu)投資預計(ji)可在7個半(ban)月(yue)內完全收回(hui)，其經濟效(xiao)益十分明(ming)顯。
按常規25MW機組參數分析，綜(zong)合(he)折算機組的熱效率可(ke)提高1.125%，供電(dian)煤(mei)(mei)耗4.830g/KW.h,年節煤(mei)(mei)1687.5噸(dun),每(mei)(mei)噸(dun)按300元計算,則每(mei)(mei)臺(tai)機組每(mei)(mei)年可(ke)節約人民幣50.625萬元。單臺(tai)膠球清洗裝置全部投資（設備費(fei)用、輔助材料(liao)、管道、工時(shi)等）綜(zong)合(he)費(fei)用20萬元，全部投資預計可(ke)在5個半月(yue)內(nei)完(wan)全收回，其經(jing)濟效益(yi)十分明顯。
