Izinto eziluncedo ekuqaqambekeni okuqaqambileyo kwe-tubs yentsimbi engenasitayile

Iityhubhu zentsimbi ezingafezekanga zizixhobo ezibalulekileyo zeshishini ezisetyenziswa ngokubanzi kwiPetrochemical, ulwakhiwo, amayeza, kunye nemizi mveliso yokutya. Ukomeleza intsebenzo kunye nobomi obude beentsimbi ezingenasitali, ukuqaqamba okuqaqambileyo kuye kwaba yinkqubo yonyango olubalulekileyo. Ukuqaqanjelwa okuqaqambileyo akuphuculi kuphela iipropathi zoomatshini beetyhubhu zentsimbi ezingenasitali kodwa zikwandisa ukunganyangeki kwabo kunye nomgangatho womhlaba. Eli nqaku liza kuthetha ngezinto eziluncedo lokuqaqamba okuqaqambileyo kwezi tyheli zentsimbi ezingenasiseko ngokweenkcukacha.

1. Ukuphuculwa kokunganyangeki kwe-corrosion

Ngexesha lenkqubo yokuncipha kobushushu isimo seqondo, iityhubhu zentsimbi ezingenasitali zishushu kumaqondo obushushu aphezulu (okwethutyana ngaphezulu kwe-1050 ° C) kwaye emva koko kupholile ngokukhawuleza. Oku kuncipha ngokufanelekileyo ii-carbides kunye nezinye izinto zolwabiwo kwintsimbi engenasibala, ukuqinisekisa ukusasazwa okulinganayo kwezi zinto ngaphakathi kweMatrix, ukwenza ubume be-gomogeneneous austitic. Le meko iyunifomu iyongeza kakhulu ukunganyangeki kwe-corrosion yeetyhubhu zentsimbi ezingenasimo, ngakumbi kwiindawo ezine-asidi, ialkalis, neetyuwa.

2. Iipropathi zoomatshini

Iipropathi zoomatshini bezityholo zentsimbi ezingenasitali ziphuculwe kakhulu emva kokukhanya okuqaqambileyo. Iqondo lobushushu eliphakamileyo kunye nenkqubo yokupholisa ngokukhawuleza ikhuphe ngokufanelekileyo uxinzelelo lwangaphakathi kwaye liphucule ubume bengqolowa, ngaloo ndlela kukhulisa ubunzima kunye namandla empahla. Ukongeza, ukuqaqamba okuqaqambileyo kunokuphelisa ukwenza izinto ezikhulayo zomsebenzi, ukwenza iityhubhu zentsimbi ezingenakumbi zilula ukwenza xa kusenziwa emva koko.

3. Ukonyusa ukukhanya

Ukuqaqanjelwa okuqaqambileyo kuqhutywa kwimozulu yokukhusela (enje nge-hydrogen okanye i-amonia engalunganga), ethintela ngokufanelekileyo i-oxidotion kwaye igcine umhlaba oqaqambileyo wensimbi. Umgangatho womphezulu we-tubs yentsimbi engenasitali iphuculwe kakhulu emva kokuqaqamba okuqaqambileyo, okukhokelela kwinkangeleko egudileyo necocekileyo. Lo mgangatho uphambili akaphumi nje kuphela isibongozo se-tubs esinentsimbi kodwa unciphise indleko zokulungisa kunye nokucoca.

4. Ukuphuculwa kokuphuculwa kozinzo

Ngokuphelisa uxinzelelo lwentsalela ngaphakathi kweetyhubhu zentsimbi ezingenasitali, iqaqambile iphucula kakhulu uzinzo lwezinto ezibonakalayo. Oku kubaluleke kakhulu kwizicelo ezifuna imilinganiselo ephambili, ezinje ngezixhobo zonyango kunye nezixhobo ezilungileyo. Kula masimi, nkqu notshintsho oluncinci olunokuchaphazela ukusebenza ngokufanelekileyo kwezixhobo, ukwenza uzinzo olubalulekileyo.

5. Inkonzo yenkonzo eyandisiweyo

Ngokwenza ukunganyangeki kwe-corrosion, iipropathi zoomatshini, kunye nomgangatho womphezulu weetyhubhu zentsimbi ezingenangqondo, ukuhambisa izinto eziqaqambileyo kudlulela kwinkonzo yenkonzo yezinto. Kwizicelo ezisebenzayo, iityhubhu zentsimbi ezingenasitali ezinokuthambeka zinokuphelisa ukumelana nokuziphatha okungqongileyo kunye nokunxiba koomatshini, ukunciphisa indawo yolondolozo kunye nokupheliswa kweendleko zokugcina.

I-6. Izibonelelo zokusiNgqongileyo

Ukuqaqanjelwa okuqaqambileyo kunezibonelelo ezibalulekileyo zokusingqongileyo. Inkqubo yokuthathwa kwemveli kunye ne-Playa yokuphola ivelisa amanzi amdaka eekhemikhali kunye nenkunkuma eqinileyo, ngelixa i-Ations eqaqambileyo eqhutywa kwimo yendawo ekhuselayo ivele phantsi kwamanzi amdaka okanye inkunkuma, intlanganiso yendalo esingqongileyo. Ngapha koko, ukungqubana okuqaqambileyo kunokunciphisa amanyathelo okusebenza okulandelayo, ukwehla okungaphezulu kokusetyenziswa kwamandla kunye nenkunkuma yezixhobo.

Ukuqukumbela, ukuqaqanjelwa okuqaqambileyo kweetyhubhu zentsimbi ezingenakwelfowuni kunika izibonelelo ezibalulekileyo ekuphuculeni ukunganyangeki, ukuphucula ubume boomatshini, ukuphucula ukuqaqamba komhlaba, ukuphucula ubomi benkonzo, kunye nokubonelela ngeengenelo zendalo. Ngenkqubela phambili eqhubekayo yobuchwephesha kunye nokwandiswa kweendawo zokwenza isicelo, i-Anneing eqaqambileyo iya kudlala indima ebaluleke ngakumbi ekwenzeni iityhubhu zentsimbi ezingenasiseko.
