Ukuhlanzwa kwezishintshisi zokushisa ezifakwe emanzini kanye nezinye izinto zokusebenza sekuphenduke isixhumanisi esibalulekile nesibalulekile ekukhiqizeni izimboni, ikakhulukazi ezitshalweni zamandla e-petrochemical kanye ne-thermal.Yiziphi izizathu kanye nezinqubo ezibalulekile zomsebenzi zokuhlanza isishintshi sokushisa esifakwe imali?Ake ngikuchazele.
Enqubweni yokukhiqiza imboni yamakhemikhali yokuhlanza, ngenxa yezizathu eziningi, kuzokwakhiwa ama-coking amaningi, ukungcola kwamafutha, isikali, i-sediment, imikhiqizo yokugqwala, i-polymer, isikhunta, njll.,snjenge-algae ne-slime.Ukungcola okuwumphumela kuzobangela ukuthi okokusebenza namapayipi kuhluleke, futhi ukukhiqizwa kwesistimu yedivayisi kuzokwehla, futhi ukusetshenziswa kwamandla nezindleko zempahla zizokhuphuka.Ukulahlekelwa kwezomnotho, ngisho nezingozi zokukhiqiza eziyingozi zingenzeka.
Ngokuvamile kunezindlela ezimbili zokuhlanza izimboni zokuhlanza isishintshi sokushisa esihlanganisiwe: ukuhlanza amakhemikhali nokuhlanza indiza yamanzi enengcindezi ephezulu.Kodwa isikhathi eside, amasu okuhlanza endabuko kanye nezindlela zokwelapha, njengezindlela zemishini, amanzi anengcindezi ephezulu, ukuhlanza amakhemikhali (i-pickling), ukuvimbela isikali, njll., akukwazi ukuxazulula inkinga ngokuphumelelayo futhi kungabangela umonakalo omkhulu kumishini ngokwayo, umzimba womuntu kanye nemvelo.Ngokuthuthuka okusheshayo kwezimboni zanamuhla, ukusetshenziswa kwamanzi okupholisa akugcini nje ukwandisa, kodwa futhi isilinganiso esikhona emishini yokushintshanisa ejikelezayo enkulu ayikwazi ukuhlanzwa ngokwesayensi, okuholela ekusetshenzisweni kwamandla kanye nokulimala kwemvelo, futhi kunciphisa ukusebenza kahle kokusebenza.Enqubweni yokukhiqiza imboni yamakhemikhali yokuhlanza, ngenxa yezizathu eziningi, kuzokwakhiwa ama-coking amaningi, ukungcola kwamafutha, isikali, i-sediment, imikhiqizo yokugqwala, i-polymer, isikhunta, njll.,njenge-algae ne-slime.Ukungcola okuwumphumela kuzobangela ukuthi okokusebenza namapayipi kuhluleke, futhi ukukhiqizwa kwesistimu yedivayisi kuzokwehla, futhi ukusetshenziswa kwamandla nezindleko zempahla zizokhuphuka.Ukulahlekelwa kwezomnotho, ngisho nezingozi zokukhiqiza eziyingozi zingenzeka.
Izinqubo zokusebenza ezibaluleke kakhulu zokuhlanza i-fin heat exchanger yilezi:
- Ukunciphisa nokuhlanza.Engeza i-ejenti yokwehlisa elungisiwe kanye neyokuhlanza ngokulingana namanzi azungezayo ethangini lokuhlanza ukuze kuhlanzwe ubhayela kanye nokwehliswa.Nquma inani lamakhemikhali ngokuya kwesikhathi somjikelezo wokuhlanza kanye nenani lesikali.Ngemva kokuqinisekisa ukuthi zonke izikali ziyahlanzwa, qhubekela endleleni yokuhlanza elandelayo.
- Hlanza ngamanzi ahlanzekile.Ngemuva kokuxhuma izinto zokuhlanza ku-boiler, zihlanze ngamanzi ahlanzekile imizuzu engu-10, hlola isimo sesistimu, uhlole ukuthi kukhona ukuvuza, futhi uhlanze ukugqwala okuntantayo ngesikhathi esifanayo.
- Ukuhlanzwa kwe-strip anti-corrosion.Engeza i-ejenti yokukhumula phezulu kanye ne-ejenti ekhipha kancane ngokulingana namanzi ajikelezayo ethangi lokuhlanza bese wenza ukuhlanza imizuzu engu-20 ukuze uhlukanise isikali ezingxenyeni ezihlanziwe.
- Ukwelashwa kwe-Passive enamathela.Engeza i-passivation coating agent ukuze wenze ukwelashwa kwe-passivation coating ohlelweni lokuhlanza ubhayela ukuvimbela ukugqwala nokwakheka okusha kwamapayipi nezingxenye.
