Indlela yokucoca i-fin exchanger heat

Ukucocwa kokutshintsha kobushushu kunye nezinye izixhobo ziye zaba likhonkco elibalulekileyo nelibalulekileyo kwimveliso yamashishini, ngakumbi kwizityalo zepetrochemical kunye ne-thermal power.Ziziphi izizathu kunye neenkqubo ezibalulekileyo zomsebenzi wokucoca ubushushu obufihliweyo?Makhe ndikucacisele.

Kwinkqubo yokuvelisa imveliso yeekhemikhali zokucoca, ngenxa yezizathu ezininzi, i-coking eninzi, ukungcola kwe-oyile, isikali, intlenga, iimveliso ze-corrosion, i-polymer, i-fungi, njl.,snjenge-algae kunye ne-slime.Ukungcola okubangelwayo kuya kubangela ukuba izixhobo kunye nemibhobho ingaphumeleli, kwaye imveliso yenkqubo yesixhobo iya kuncipha, kwaye ukusetyenziswa kwamandla kunye neendleko zempahla ziya kwanda.Ilahleko yezoqoqosho, kwaneengozi eziyingozi zemveliso zingenzeka.

Zimbini iindlela zokucocwa komshicileli wokucocwa kokutshintsha ubushushu: ukucocwa kweekhemikhali kunye nokucoca ijethi yamanzi ngoxinzelelo oluphezulu.Kodwa ixesha elide, iindlela zokucoca zendabuko kunye neendlela zonyango, njengeendlela zoomatshini, amanzi aphezulu, ukucocwa kweekhemikhali (i-pickling), inhibition yesikali, njl., ayikwazi ukuyicombulula ngempumelelo ingxaki kwaye inokubangela umonakalo omkhulu kwisixhobo ngokwawo, umzimba womntu kunye nokusingqongileyo.Ngophuhliso olukhawulezayo loshishino lwanamhlanje, ukusetyenziswa kwamanzi okupholisa akunyuki nje kuphela, kodwa kunye nomlinganiselo okhoyo kwizixhobo zokutshintshiselana ezijikelezayo ezinkulu azikwazi ukucocwa ngokwesayensi, okukhokelela ekusebenziseni amandla kunye nomonakalo wokusingqongileyo, kunye nokunciphisa ukusebenza kakuhle.Kwinkqubo yokuvelisa imveliso yeekhemikhali zokucoca, ngenxa yezizathu ezininzi, i-coking eninzi, ukungcola kwe-oyile, isikali, intlenga, iimveliso ze-corrosion, i-polymer, i-fungi, njl.,ezifana ne-algae kunye ne-slime.Ukungcola okubangelwayo kuya kubangela ukuba izixhobo kunye nemibhobho ingaphumeleli, kwaye imveliso yenkqubo yesixhobo iya kuncipha, kwaye ukusetyenziswa kwamandla kunye neendleko zempahla ziya kwanda.Ilahleko yezoqoqosho, kwaneengozi eziyingozi zemveliso zingenzeka.

Ezona nkqubo zibalulekileyo zomsebenzi zokucoca umtshintshisi wobushushu zezi:

1. Ukunciphisa kunye nokucoca.Yongeza ukuhla okulungisiweyo kunye ne-ejenti yokucoca ngokulinganayo namanzi ajikelezayo kwitanki yokucoca ukucoca kwibhoyila kunye nokuhla.Qinisekisa ubungakanani beekhemikhali ngokwexesha lokujikeleza kokucoca kunye nomlinganiselo wesikali.Emva kokuqinisekisa ukuba zonke izikali zihlambulukile, qhubela phambili kwindlela yokucoca elandelayo.
2. Hlanza ngamanzi acocekileyo.Emva kokudibanisa izixhobo zokucoca kwibhoyili, yihlambulule ngamanzi acocekileyo imizuzu eyi-10, khangela imeko yenkqubo, khangela ukuba kukho ukuvuza, kwaye uhlambulule i-rust ejikelezayo ngexesha elifanayo.
3. Ukucocwa kwe-strip anti-corrosion.Yongeza i-agent ye-surface stripping agent kunye ne-slow-release-ejenti ngokulinganayo namanzi ajikelezayo kwitanki yokucoca kwaye wenze ukucoca imizuzu engama-20 ukuhlula isikali kwiindawo ezihlambulukileyo.
4. Ukunyangwa kokugquma.Yongeza i-ejenti yokwaleka ukwenza i-passivation coating treatment kwisixokelelwano sokucoca kwibhoyila ukuthintela umhlwa kunye nokwakheka komhlwa kwemibhobho kunye namalungu.
