Ioli yokudlulisa ubushushuluhlobo lweoyile ekhethekileyo enozinzo oluhle lwe-thermal olusetyenziselwa ukuhanjiswa kobushushu obungathanga ngqo.I-oyile ye-Heat conduction ayikwazi nje ukuhlangabezana neemfuno zokufudumeza kunye nokupholisa ubushushu obuhlukeneyo kuluhlu olubanzi lwamaqondo obushushu, kodwa kwakhona ukuqonda iimfuno zenkqubo yokufudumeza ubushushu obuphezulu kunye nokupholisa ubushushu obuphantsi kunye neoli yokushisa ubushushu obufanayo kwinkqubo efanayo, enokuthi. ukunciphisa ubunzima benkqubo kunye nokusebenza.Ngoko ke, inkqubo yokufudumeza i-oyile yokushisa isetyenziswa kakhulu kwi-chemical fiber, izinto eziphathekayo kunye namanye amashishini.
Iimpawu zenkqubo yeoli yokuqhuba ubushushu:
I-1.Ngaphantsi kwemeko yoxinzelelo oluphantse lwe-atmospheric, inokufumana ubushushu obuphezulu kakhulu bokusebenza - oko kukuthi, kunokunciphisa kakhulu uxinzelelo lokusebenza kunye neemfuno zokhuseleko lwenkqubo yokufudumeza ubushushu obuphezulu, ukuphucula ukuthembeka kwenkqubo kunye nezixhobo;
I-2.Inkqubo yokufudumeza i-oyile ehambisa ukushisa ishiya inkqubo yokucoca amanzi kunye nezixhobo, eziphucula ukusebenza kakuhle kwe-thermal yenkqubo kunye nokunciphisa umthwalo wokugcinwa kwezixhobo kunye nemibhobho - oko kukuthi, utyalo-mali lokuqala kunye neendleko zokusebenza zenkqubo yokufudumeza inako. kuncitshiswe.
Imingcipheko enokubakho yenkqubo ye-oyile eshushu:
I-1.Ngenxa yokushisa kwendawo yendawo yokufudumeza ngexesha lokusetyenziswa kweoli yokushisa ukushisa, ukuphendulwa kwe-thermal cracking kulungele ukwenzeka, okubangelwa i-oligomers eguquguqukayo kunye nephantsi.I-Polymerization phakathi kwe-oligomers ivelisa iipholima ezinganyibilikiyo nezinganyibilikiyo, ezingathinteli kuphela ukuhamba kweemveliso ze-oyile kwaye zinciphise ukusebenza kakuhle kobushushu obufanayo, kodwa zikwabangela ukuba nokwenzeka kokuguquka kobushushu obugqithisileyo bendawo kunye nokugqabhuka kombhobho.
I-2.I-oyile yokutshintshwa kobushushu kunye nokuchithwa kwe-air kunye nokuzaliswa kwenkqubo yokuthutha ubushushu yi-oxidation reaction of air residual phantsi kwemeko yokufudumeza, kunye nokwakheka kwe-asidi ye-organic kunye ne-colloid ibambelela kumbhobho we-oyile, engachaphazeli kuphela ubomi benkonzo yokudlulisa ubushushu kunye ithintela umbhobho, kodwa yenza lula ukuhlwa kweasidi yombhobho kwaye yandise umngcipheko wokuvuza kokusebenza kwenkqubo.
Iingozi zenkqubo yokufudumeza i-oyile yokuhambisa ubushushu ziquka:Umlilo wetanki yokugquma ubushushu, umlilo wetanki yokwandisa kunye ne-thermal insulation layer, umlilo wokufudumeza ubushushu kwindawo yokusebenza ye-oyile, umlilo kunye nogqabhuko-dubulo lwetanki yokugcina ubushushu, umlilo kunye nogqabhuko-dubulo lwe-oyile yokuhambisa ubushushu okanye i-reactor (iketile), uqhushumbo eziko, etc. Inokubonwa ukuba ezininzi iingozi inkqubo thermal zokufudumeza oyile zingaphezulu okanye ngaphantsi ezinxulumene ukuvuza.
Iimfuno zevalvu zomgangatho wobugcisa kunye neenkcukacha zoyilo kwiinkqubo zeoyile eshushu ziquka: an ivalve yokukhuphakweyona ndawo iphakamileyo kunye nevalve yokuvuthela kweyona ndawo isezantsi.Umgca wepayipi yenkqubo yeoli eshushu kufuneka idibaniswe nayoiiflangengaphandle kojongano lwesixhobo, ujongano lwesixhobo okanye iivalvu.Zonke ezinye ii-interfaces zi-welded.Iiflangekufuneka kumiselwe umphezulu wegroove, kwaye uxinzelelo lwegama kufuneka lungabi ngaphantsi kwe-1.6MPa.Kuba ubushushu conduction ioli kunye lobushushu ngaphezu 300 degrees, uxinzelelo lwegama leiflangeakufunekanga ibe ngaphantsi kwe-2.5MPa.Iiflangekufuneka i-butt idityaniswe endaweni yeeflange eziphothiweyo.I-flange gasket yenkqubo yeoli eshushu ayivumelekanga ukuba isebenzise ipleyiti yerabha ye-asbestos, i-metal winding pad okanye i-graphite composite pad eyandisiweyo kufuneka isetyenziswe.Inkqubo ye-oyile eshushu kufuneka ibonelelwe ngevalve yokhuseleko, kwaye ivelufa yokhuseleko kufuneka ibe ngumbhobho otywiniweyo wokhuseleko.
Izinto zevalvu yenkqubo yeoli eshushu aziyi kugalelwa ngentsimbi okanye intsimbi engeyiyo intsimbi.Uthathela ingqalelo uxinzelelo lwayo oluphantsi, ubushushu obuphezulu kunye nokungena komelele ngakumbi, ngokwemigangatho yoyilo lobugcisa, umbhobho we-oyile oshushu osikiweyo kufuneka usebenzise ivalvu yokuvala isivalo, ivalve elawulayo kufuneka isebenzise ivalve elawula umbhobho wetywina, ivalve yokhuseleko isebenzisa ivalve yokhuseleko evulekileyo evulekileyo.
Ngenxa yeempawu zokuzinza kwe-oxidation ye-oyile yokuqhuba ubushushu, ukuvuza kwevalve yeoli eshushu akuyi kubangela kuphela ukutsha kwe-insulation layer okanye ukutsha kunye nokuqhuma kwezixhobo, kodwa kubangele ukusabela kwe-oxidation ye-oyile yokuqhuba ubushushu kunye nomoya onyibilikisiweyo. imeko yobushushu, ukuvelisa ivalve ye-asidi ephilayo ye-corrosion yangaphakathi.Ngoko i-valve yeoli eshushu ayifanele ingenzi kuphela ukuvuza kwangaphakathi, kodwa kwakhona musa ukuvuza kwangaphandle.
Ukupakisha ngokubanzi ivalve yeglowubhu yokupakisha ngokubumba ukusetyenzwa kwegraphite, ukuba ukucoceka kwegraphite akwanelanga, ukuxhathisa kwayo kweoyile kuya kuba mbi kakhulu, xa i-oyile yokuqhuba ubushushu ingena kwigrafu yokupakisha, ukungcola okuthile kwigraphite kulula ukunyibilika ngokuqhutywa kobushushu. i-oyile, ekhokelela kwi-graphite powder, ayikwazi ukwenza ukupakishwa kwegraphite ukufezekisa umphumo wokutywina, oku kungunobangela oyintloko wokupakisha ivalve ehlala ivuza.Ibellow seal ithintela ukudibana ngokuthe ngqo phakathi kweoyile eshushu kunye negraphite, nto leyo ecombulula ingxaki yokuvuza kweoyile eshushu kwisiqu xa kunyibilika ukupakishwa kwegraphite.
Ngenxa yokuba i-permeability ye-oyile yokuqhuba ubushushu inamandla kakhulu (malunga namaxesha angama-50 okomphunga), ukuba itywina lokuzalisa likhethiwe, kulula kakhulu ukuvuza, okukhokelela kwinkcitho yeoli eshushu, izixhobo ezingcolileyo kunye nomhlaba, kunye nesakhiwo se-bellows. inokuqonda ngokupheleleyo ukuvuza kwe-zero, kwaye akukho malungu okunxiba.
Ngenxa yengozi enokubakho yokuzinza kwe-oxidation ye-oyile yokuqhuba ubushushu, iindawo zangaphakathi zevalve zenziwe ngensimbi engenasici, enokumelana nobushushu obuphezulu be-425 ℃, ukumelana nokugqwala, kunye nokutshintsha kulula ngakumbi.
Ukusuka kwimbono yobomi ngokubanzi, ubomi benkonzo jikeleleivalve yokutywinaingcono kunezinye iivalvu.Ioli yokudlulisa ukushisa ine-viscosity ephezulu kunye nokuchasana nokuhamba okukhulu kwimeko ebandayo.I-valve core ithatha uhlobo lokuvula ngokukhawuleza, olunokuphucula izinga lokuhamba kwaye linqobe ukuchasana nokuhamba kakuhle xa uqala.Ngoko ke, ukuze kuqinisekiswe ukuzinza kwemveliso, kodwa ukuze kuncitshiswe eyona ndleko yokusebenza, inkqubo yeoli yokudlulisa ubushushu kufuneka ikhethe undoqo wevalve yokuvula ngokukhawuleza.ivalve yokumisa itywina, ayinakukhetha ivalve yokumisa itywina okanye ivalve jikelele.
Ivalve yeglowubhu yokutywina iBellowseveliswe yi-BESTOP ifaneleke kakhulu ukunqumla umbhobho wokuthuthwa kwenkqubo yeoli eshushu.
