Indlela yokususa iigesi ezingenakucondensable ezifana nomoya kwiinkqubo zomphunga?

Eyona mithombo iphambili yeegesi ezingacondensable ezifana nomoya kwiinkqubo zomphunga zezi zilandelayo:
(1) Emva kokuba inkqubo yomphunga ivaliwe, kwenziwa ivacuum kwaye kufunxelwe umoya
(2) Ibhoyila yamanzi ihambisa umoya
(3) Unikezelo lwamanzi kunye namanzi ajikiweyo adibana nomoya
(4) Indawo yokondla kunye nokuthulula izixhobo zokufudumeza ezingaphakathi

Iigesi ezingaguqukiyo ziyingozi kakhulu kwi-steam kunye ne-condensate systems
(1) Ivelisa ukuxhathisa kwe-thermal, ichaphazela ukuhanjiswa kobushushu, inciphisa imveliso yobushushu, inyusa ixesha lokufudumeza, kwaye inyusa iimfuno zoxinzelelo lomphunga.
(2) Ngenxa yokungahambi kakuhle kwe-thermal yomoya, ubukho bomoya buya kubangela ukufudumeza okungalinganiyo kwemveliso.
(3) Ekubeni ukushisa kwe-steam kwi-gas non-condensable ayinakumiselwa ngokusekelwe kwi-gauge ye-pressure gauge, oku akuvumelekanga kwiinkqubo ezininzi.
(4) I-NO2 kunye ne-C02 equlethwe emoyeni inokugqwesa ngokulula i-valve, i-heat exchangers, njl.
(5) Irhasi engacondensable ingena kwi-condensate system yamanzi ibangela ihamile yamanzi.
(6) Ubukho bama-20% omoya kwindawo yokufudumeza buya kubangela ukuba ubushushu bomphunga behle ngaphezu kwe-10°C. Ukuze kuhlangatyezwane nemfuno yobushushu bomphunga, imfuno yoxinzelelo lomphunga iya kwandiswa. Ngaphezu koko, ubukho berhasi engacondensable buya kubangela ukuba iqondo lobushushu lomphunga lehle kunye nokutshixa okunzulu komphunga kwinkqubo ye-hydrophobic.

Phakathi kwemigangatho emithathu yokuchasana nobushushu kwicala lomphunga - ifilimu yamanzi, ifilimu yomoya kunye nomgangatho wesikali:

Olona xhathiso lushushu luvela kumaleko womoya. Ubukho befilimu yomoya kwindawo yokutshintshiselana kobushushu bunokubangela iindawo ezibandayo, okanye ngakumbi, ukukhusela ngokupheleleyo ukuhanjiswa kobushushu, okanye ubuncinci kubangele ukufudumala okungalinganiyo. Enyanisweni, ukuxhathisa kwe-thermal yomoya kunamaxesha angaphezu kwe-1500 yentsimbi kunye nentsimbi, kunye namaxesha angama-1300 okobhedu. Xa umlinganiselo womoya oqokelelweyo kwindawo yokutshintsha ubushushu ufikelela kuma-25%, iqondo lobushushu lomphunga liya kuhla kakhulu, ngaloo ndlela linciphisa ukusebenza kakuhle kokudluliselwa kobushushu kwaye likhokelela ekungaphumeleli kokuvala inzala ngexesha lokuvala inzala.

Ngoko ke, iigesi ezingaguqukiyo kwi-steam system kufuneka zipheliswe ngexesha. Eyona isetyenziswa ngokuqhelekileyo ivalve yokukhupha umoya we-thermostatic kwimarike okwangoku inengxowa etywiniweyo ezaliswe lulwelo. Indawo yokubilisa yolwelo ingaphantsi kancinci kunobushushu bokugcwala komphunga. Ngoko xa umphunga ococekileyo ujikeleza isikhwama esitywiniweyo, ulwelo lwangaphakathi luyaba ngumphunga kwaye uxinzelelo lwalo lubangela ukuba ivalve ivale; xa kukho umoya kumphunga, ubushushu bawo bungaphantsi kunomphunga ococekileyo, kwaye ivelufa izivula ngokuzenzekelayo ukukhulula umoya. Xa indawo ejikelezileyo ingumphunga ococekileyo, i-valve ivala kwakhona, kwaye i-valve yokukhupha i-thermostatic isusa ngokuzenzekelayo umoya nangaliphi na ixesha ngexesha lokusebenza kwenkqubo ye-steam. Ukususwa kweegesi ezingagungqiyo kunokuphucula ukuhanjiswa kobushushu, ukonga amandla kunye nokwandisa imveliso. Ngelo xesha, umoya ususwe ngexesha ukuze kugcinwe ukusebenza kwenkqubo ebaluleke kakhulu ekulawuleni ukushisa, ukwenza ukushisa okufanayo, kunye nokuphucula umgangatho wemveliso. Ukunciphisa umhlwa kunye neendleko zokugcina. Ukukhawulezisa isantya sokuqalisa kwesixokelelwano kunye nokunciphisa ukusetyenziswa kokuqalisa kubalulekile ekukhupheni iinkqubo zokufudumeza umphunga kwindawo enkulu.

Ivalve yokukhupha umoya yenkqubo yomphunga ifakwe kakuhle ekupheleni kombhobho, kwikona efileyo yesixhobo, okanye indawo yokugcina izixhobo zokutshintshiselana ngobushushu, nto leyo enceda ekuqokeleleni nasekupheliseni iigesi ezingacondensable. . Ivalve yebhola yezandla kufuneka ifakwe phambi kwevalve yokukhupha i-thermostatic ukuze umphunga ungayeki ngexesha lokugcinwa kwevalve yokuphuma. Xa inkqubo yomphunga ivaliwe, ivalve yokukhupha ivuliwe. Ukuba ukuhamba komoya kufuneka kubekwe yedwa kwihlabathi langaphandle ngexesha lokuvalwa, ivalve yokukhangela i-soft-sealing ye-soft-sealing encinci inokufakwa phambi kwevalve yokukhupha.
