Kucheneswa kwemafinned heat exchanger nemimwe midziyo yave chinhu chakakosha uye chakakosha chinongedzo mukugadzirwa kwemaindasitiri, kunyanya mune petrochemical uye thermal power plant.Ndezvipi zvikonzero uye maitiro akakosha ebasa ekuchenesa kupisa kwekupisa?Rega ndikutsanangurire.
Mukugadzira indasitiri yekuchenesa makemikari indasitiri, nekuda kwezvikonzero zvakawanda, yakawanda yekubika, tsvina yemafuta, chiyero, sediment, corrosion zvigadzirwa, polymer, fungi, nezvimwe zvichaumbwa mufin heat exchanger michina uye pombi.,szvakadai sealgae uye slime.Tsvina inokonzeresa inokonzeresa kuti michina nemapombi zvikundikane, uye chigadzirwa chemuchina chinodzikira, uye mashandisiro esimba uye mutengo wezvinhu uchawedzera.Kurasikirwa kwehupfumi, kunyangwe njodzi dzekugadzira dzinokuvadza dzinogona kuitika.
Pane kazhinji nzira mbiri dzekucheneswa kwemaindasitiri ekuchenesa kupisa kunopisa: kuchenesa kemikari uye kuchenesa kwejeti yemvura.Asi kwenguva yakareba, maitiro ekuchenesa echinyakare uye nzira dzekurapa, senge nzira dzemuchina, yakanyanya-kudzvanywa mvura, kuchenesa kemikari (pickling), chiyero inhibition, nezvimwewo, haigone kugadzirisa dambudziko uye inogona kukonzera kukuvara kwakakomba kumidziyo pachayo, muviri wemunhu uye zvakatipoteredza.Nekukurumidza kukura kweindasitiri yemazuva ano, kushandiswa kwemvura inotonhorera hakusi kungowedzera chete, asiwo chiyero chiripo mumichina yakakura inotenderera yekutsinhana haigone kucheneswa nesainzi, izvo zvinotungamira mukushandiswa kwesimba uye kukanganisa kwezvakatipoteredza, uye kunoderedza kushanda zvakanaka.Mukugadzira indasitiri yekuchenesa makemikari indasitiri, nekuda kwezvikonzero zvakawanda, yakawanda yekubika, tsvina yemafuta, chiyero, sediment, corrosion zvigadzirwa, polymer, fungi, nezvimwe zvichaumbwa mufin heat exchanger michina uye pombi.,zvakaita sealgae uye slime.Tsvina inokonzeresa inokonzeresa kuti michina nemapombi zvikundikane, uye chigadzirwa chemuchina chinodzikira, uye mashandisiro esimba uye mutengo wezvinhu uchawedzera.Kurasikirwa kwehupfumi, kunyangwe njodzi dzekugadzira dzinokuvadza dzinogona kuitika.
Iwo akanyanya kukosha maitiro ekushanda kwefin heat exchanger yekuchenesa ndeaya:
- Descaling uye kuchenesa.Wedzera yakagadzirira kudzika uye yekuchenesa mumiririri maererano nekutenderera kwemvura mukuchenesa tangi yekuchenesa boiler nekudzikisa.Sarudza huwandu hwemakemikari zvichienderana nenguva yekuchenesa uye chiyero chechiyero.Mushure mekuita chokwadi chekuti zviyero zvese zvakacheneswa, enda kune inotevera nzira yekuchenesa.
- Shamba nemvura yakachena.Mushure mekubatanidza midziyo yekuchenesa kune bhaira, ichenese nemvura yakachena kwemaminitsi gumi, tarisa mamiriro ehurongwa, tarisa kana pane kudonha, uye chenesa ngura inoyangarara panguva imwe chete.
- Kubvisa anti-corrosion kuchenesa.Wedzera iyo yepamusoro yekubvisa mumiriri uye inononoka-kuburitsa mumiriri maererano nemvura inotenderera yetangi rekuchenesa uye ita kuchenesa kwemaminetsi makumi maviri kuparadzanisa chiyero kubva kune dzakacheneswa zvikamu.
- Passive coating treatment.Wedzera passivation coating agent kuitisa passivation coating kurapwa mune boiler yekuchenesa system kudzivirira ngura uye kutsva ngura kugadzira mapaipi uye zvikamu.
