(6) I-compressor yegesi yensimbi ngokuvamile inezinhlobo ezintathu: umshini wokukulufa ongenawo uwoyela, uhlobo lwepiston nohlobo lwe-centrifugal.Ngoba uhlobo piston kanye centrifugal uhlobo uwoyela yemvelo khulula, ngakho akudingeki uwoyela ukususwa idivayisi, kudingeka kuphela ukusekela idivayisi omiswe (ukususwa kwamanzi) kanye nesihlungi ukunemba (ngaphezu izinhlayiya eziqinile) kungaba;Umshini wesikulufa ngokuvamile unezinhlobo ezimbili zamafutha futhi akukho ukususwa kwamafutha namafutha, umshini wokujova uwoyela wokujova uwoyela udinga ukusetha idivayisi yokususa uwoyela, ngesikhathi esifanayo udinga ukusetha isihlungi sokususa uwoyela esinembayo kakhulu, ukuze uhlangabezane nezidingo inqubo, inzuzo yalolu hlobo ishibhile;Isikulufu esingenawo uwoyela sisebenzisa i-rotor eyomile noma ukugcotshwa kwamanzi, lolu hlobo lwenzuzo alukho uwoyela, ukonakala ukuthi intengo ibiza kakhulu.Umthamo wegesi ongaphansi kuka-500NM ³/h ulungele ukukhetha uhlobo lwepiston;Ivolumu yegesi ku-2000Nm³/h elandelayo ifanele umshini oyisikulufa noma umshini wepiston;Umthamo wegesi ungaphezu kuka-2000Nm³/h, okungukuthi, amamodeli amathathu angakhethwa.Uma umthamo wegesi mkhulu, i-compressor ye-centrifugal inenzuzo yezingxenye ezigqoke kancane, futhi kulula ukuyigcina futhi ingabizi.

I-compressor yensimbi isetshenziswa lapho ushayela, futhi ikhishwa isihlanzi se-molecular sieve ngemva kokusebenza okuvamile.

Isistimu yokupholisa kuqala

Umbhoshongo opholile emoyeni wesistimu yokupholisa ngaphambili unezinhlobo ezimbili: umjikelezo ovaliwe (umbhoshongo opholile emoyeni uhlukaniswe izingxenye ezingaphezulu nezingaphansi, futhi amanzi ayiqhwa azungeza phakathi kwengxenye engenhla yombhoshongo opholile nomoya. ) kanye nomjikelezo ovulekile (i-inlet kanye nohlelo lwamanzi ajikelezayo).Umjikelezo ovaliwe usetshenziswa ikakhulukazi ezitshalweni zamakhemikhali ezinekhwalithi embi yamanzi, futhi amanzi ahlanzekile namakhemikhali kudingeka kwengezwe.Ukujikeleza okuvulekile kusetshenziswa kakhulu, kodwa uhlelo lwamanzi ajikelezayo nalo ludinga ukugcwalisa amanzi ahlanzekile njalo, futhi uhlelo lokupholisa ngaphambi kwesikhathi ludinga ukucabangela izimo zasehlobo.

Umbhoshongo wokupholisa umoya ngokuvamile udizayinelwe phansi kweringi yensimbi engenasici engu-1 m Φ76 (izinga lokushisa eliphezulu), 3 m Φ76 indandatho ye-polypropylene ethuthukisiwe ye-polypropylene (i-flux enkulu), 4 m Φ50 indandatho ye-polypropylene ethuthukisiwe.

Kukhona futhi izinhlobo ezimbili zombhoshongo wokupholisa amanzi: uhlobo lwezigaba ezimbili (akukho mthombo wokupholisa wangaphandle, indle eyomile yokubuyisela i-nitrogen ebandayo yanele, ukuze uhlelo lokupholisa lwangaphambi kokupholisa luqinisekiswe, kodwa ukumelana kuphindwe kabili, (amamitha angu-7 + 7 amamitha φ50 polypropylene pall ring) kanye nohlobo lwesigaba (nomthombo wokupholisa wangaphandle, amamitha angu-8 φ50 polypropylene pall ring).

Ukwengeza, wonke ama-inlet wamanzi we-precooling system kufanele asethwe ngezihlungi (imvamisa amasethi ayi-6: amaphampu ama-4, indawo yokungena yamanzi yombhoshongo wokupholisa amanzi, indawo yokungena amanzi yohlangothi lokuhwamuka kwe-chiller yamanzi) ukuvimbela ukungcola ukuthi kungeniswe endaweni. uhlelo.Umthelela wesistimu yokupholisa kuqala utholwe ngale ndlela elandelayo: igesi yokuphuma yengxenye ephansi ye-4 m yokupakisha yayingaphansi ngo-1℃ kunamanzi angenayo;Igesi ekuphumeni kwesigaba sokupakisha esingu-8 m engxenyeni engenhla iphakeme ngo-1℃ kunamanzi.Ngokuvamile, igeji yokulinganisa izinga lokushisa isethwe engxenyeni emaphakathi yombhoshongo opholiswe umoya (unwetshwe phakathi).

Uhlelo lokuhlanza

Isistimu yokuhlanza esetshenziswa i-adsorber inokugeleza kwe-axial eqondile, umbhede olele ovundlile kanye nokugeleza kwe-radial okuqondile okuthathu.

Ukugeleza kwe-axial eqondile kusetshenziswa kakhulu ibanga le-10,000 (ububanzi bube ku-4.6m) ngaphansi kwemishini yokuhlukanisa umoya esekelayo, ukujiya kombhede 1550∽2300mm, ungqimba oluphindwe kabili kanye nongqimba olulodwa kungahlelwa, ukugeleza kwe-axial okuqondile kokugeleza kwe-adsorber ukusatshalaliswa komoya kungcono kakhulu.

Umbhede owumbhede ovundlile usetshenziselwa ikakhulukazi ukusekela imishini yokuhlukanisa umoya emikhulu nemaphakathi.Ugqinsi lombhede luyi-1150mm (isisefo semolekyuli) +350mm (iglue ye-aluminium).

I-vertical radial flow adsorber ingasebenzisa ngempumelelo indawo yangaphakathi yesiqukathi, ukuze indawo ye-adsorption layer yobubanzi obufanayo inwetshwe cishe izikhathi ezingu-1.5, ezinganciphisa ngempumelelo ukuphakama kombhoshongo, kuyilapho indlela eqondile ithatha indawo encane.Ngenxa yokuthi ukugeleza komoya kusatshalaliswa ngokulinganayo, ngokungafani ne-adsorber enezingqimba, inani le-sieve yamangqamuzana lincishiswa ngo-20%, futhi ukusetshenziswa kwamandla avuselelekayo nakho kugcinwa ngo-20%.

Kodwa-ke, ububi bokugeleza kwe-radial eqondile ukuthi isikhungo sokugeleza komoya sigxilile (umkhakha), okwenza kusheshe kunesikhathi sokungena kwe-radial evundlile (CO2 <0.5ppm).Ubukhulu bombhede bungu-1000mm+200mm, futhi ukugeleza kweradial okuqondile kungahlangabezana nokucushwa kwemishini yokuhlukanisa umoya ngaphezu kwebanga le-20,000.

Kunezindlela ezimbili zokushisisa okuvuselelayo: i-heater kagesi ne-steam heater.

Isifudumezi esishisayo sinokuvundlile (ngaphansi kwebanga lezinkulungwane ezingama-40), mpo (ngaphezu kwebanga lezinkulungwane ezingama-40), isifudumezi esisebenza kahle esithe vu (izinga eliphezulu lokusetshenziswa kwesimusi, ukonga amandla angama-20%): isakhiwo se-steam (enephuzu lokubona ukuvuza kwe-H2O);I-heater kagesi (ukusetshenziswa okukabili nokubekwe eceleni noma ukusetshenziswa okukodwa nokubekwe eceleni) ngokuhambisana (ukusetha izinga lokushisa eliphezulu kanye nokugeleza okuphansi kwe-interlock stop ukuvimbela ukusha, okokusebenza kweshubhu lokushisisa kungu-1Cr18Ni9Ti);I-heater kagesi (ihlangabezana nokuvuselelwa kabusha, 250∽300℃) kanye ne-steam ngokuhambisana;I-heater kagesi ixhunywe ochungechungeni ne-steam heater (lapho izinga lokushisa lomusi liphansi, ukumelana nokuvuselelwa kukhulu).

Uhlelo lokuhlanza futhi ludinga ukusetha ipayipi lokuvuselela i-throttle ukuze lihlangabezane nezidingo zokuqalisa.Ngaphezu kwalokho, i-valve yokuphepha inikezwa ohlangothini lwegesi evuselela kabusha, futhi i-valve yokuphepha inikezwa ohlangothini lwe-heater ye-steam ukuvimbela ukuvuza noma ukucindezela ngokweqile ohlangothini lokucindezela okukhulu kwemishini noma i-valve, kanye i-throttling overpressure.

Indlela yokugeleza yokuvuselela ifakwe i-valve ye-butterfly eyenziwa ngesandla ukuze inikeze ukumelana, ukuze wenze umbhoshongo wokusingatha usebenze kahle (noma cha, sebenzisa ukulungiswa kwesikhathi kwe-valve elawula ipayipi elikhulu).

Ngakho uhlelo lokushintshanisa ukushisa

Isistimu yokushintshanisa ukushisa i-hybrid medium design design yokugeleza ku-exchanger efanayo yokushisa, ukudlulisa ukushisa ibhalansi ezenzakalelayo ye-medium ngayinye, ukusetshenziswa kwamandla okuphansi, kodwa lokhu kungabangela wonke umshini wokushisa wenqubo yangaphakathi yokucindezelwa kwe-high pressure exchanger ukushisa, kuzoholela ekusetshenzisweni kokushisa okuphansi. ukunqwabelana kokukhula kwe-investimenti, ngakho-ke inhlangano yezinga elingenhla lika-20000 noma isishintshi sokushisa esicindezelayo samandla aphezulu aphansi ngendlela ehlukile, eyonga kakhulu, engaphansi kwamazinga angu-20000 zonke zamukela ukumiswa kwesishintshi sokushisa esinengcindezi ephezulu.

Umkhiqizo uthunyelwa

Imikhiqizo ye-oksijini enengcindezi ephansi kanye nemikhiqizo ye-nitrogen, misa ivalvu yokulawula umkhiqizo kanye nendlela yokugeleza kwe-vent, ingene kusithulisi (izingxenye zangaphakathi ze-nitrogen zensimbi ye-carbon, izingxenye zangaphakathi zomoya-mpilo wensimbi engagqwali).Izilungiselelo ze-nitrogen ezonakele zokupholisa umbhoshongo wokupholisa amanzi (indima ekhohlakele ye-nitrogen yokuvuthela, hlanganisa futhi uthukuthele, futhi ulungise ukucindezela, umphumela wombhoshongo wokupholisa wamanzi ombhoshongo ububanzi ungahlangabezana nezidingo zokukhishwa, ikakhulukazi i-nitrogen ingadlulela esimweni, yenza umbhoshongo ucindezele umfutho ophezulu, ukumelana nombhoshongo wokupholisa amanzi ku-6 kpa (ukupakishwa okuphezulu kwamamitha angu-8), amapayipi namavalvu abe ngu-4 kpa, 2 kpa womehluko we-atmospheric vent pressure, isamba esingu-12 kpa).

Ngemikhiqizo ye-oxygen enengcindezi ephezulu, i-throttling enezigaba ezimbili iyamukelwa ukuze ikhiphe umoya.Okokuqala, imibhobho yegesi yomkhiqizo wengcindezi ephezulu igeleza iye ku-10barG, ngepayipi elinciphisa i-eccentric, bese ipuleti lokunciphisa umsindo le-Monel libekwe phakathi nendawo.Bese, ububanzi bepayipi bunwetshwa ngepayipi elinciphisa i-eccentric, futhi izinga lokugeleza kwe-oxygen medium lilawulwa ngaphansi kwe-10m / s.Imikhiqizo ye-nitrogen enengcindezi ephezulu, imikhiqizo ye-nitrogen yaqala yaphonswa ku-10bar, ngokusebenzisa ipuleti lokunciphisa umsindo lensimbi engagqwali, bese ingena endaweni yomsindo wombhoshongo, izingxenye zokunciphisa umsindo we-carbon steel;I-valve ye-oxygen akufanele isetshenziswe abantu (i-valve elawulayo ayivunyelwe ukuthatha isondo lesandla, futhi i-valve yezandla ifakwe odongeni oluvikela ukuqhuma).

Umbhoshongo we-Anechoization ungabuye uhlanganiswe nesistimu ye-compressor, ukuncishiswa komsindo we-compressor booster (kubalwa ngokuhambisana nenani le-compressor yomoya), ngombhoshongo we-anechoization, kanye nomoya wokunciphisa ukucindezela kwesistimu yokuhlanza, i-booster play backflow, ingxenye yokukhipha.

Ukunwetshwa kwesistimu yesiqandisi

Kunezinhlobo ezintathu ze-expander, okungukuthi, i-low pressure expander, i-medium pressure expander kanye ne-liquid expander.

Ohlotsheni oluthile lwe-expander yegesi, ukugeleza kwevolumu enkulu kwendawo yokusebenza, kukhuphuka ukusebenza kahle.Ukugeleza okuvamile kokusebenza kahle kokunwetshwa kwengcindezi ephansi engaphezu kuka-8000Nm³ kungu-85∽88%, ukugeleza okungaphansi kuka-3000∽8000Nm³ ukusebenza kahle kuzoba phansi kuye ku-70∽80%.

I-Medium pressure expander ngokuvamile isebenzisa ephuma kwamanye amazwe (i-spare).Umthamo womoya ongu-8000Nm³/h noma ukusebenza kahle kwesandisi esingenisiwe ngaphezulu kuka-82∽91% (ukuphela kokucindezela ngamaphoyinti angu-4 ngaphansi);Ukusebenza kahle kwesandisi sasekhaya 78∽87% (ukuphela kokucindezela ngamaphoyinti angu-5 ngaphansi).

Ngaphambi kokuba umshini wokunweba uqale, kuyadingeka ukuhlanza (ukukhipha ukungcola ohlelweni lwepayipi kanye nokungcola emshinini wokunweba we-volute), bese udlulisela igesi yokuvala (ngokuvamile ehlinzekwa ukuphela kokucindezela), bese uqhuba igesi yangaphandle. ukujikeleza kanye nokujikeleza kwangaphakathi kwesistimu kawoyela.Ngemva kokuphothula ukuhlolwa okuhlanganisiwe, kungaqalwa.Ngemva kokudlula ukuhlolwa okubandayo, kungabanda kuqiniswe.Ukuqala okubandayo kudinga ukuqala i-heater yethangi, okungadingekile ngemuva kokusebenza okujwayelekile.Ngalesi sikhathi, ukushisa nokubanda kwe-bearing kuye kwalinganiswa.

Ingqikithi ye-expander ye-liquid ukusebenzisa ikhanda lokucindezela koketshezi olucindezelayo ukwenza umsebenzi we-hydraulic (ngasikhathi sinye, i-enthalpy yoketshezi iyancishiswa, kepha uma iqhathaniswa negesi, ikude kakhulu).Ngokuvamile, umshini wokuhlukanisa umoya wokucindezelwa wangaphakathi ongaphezu kuka-40,000 ungasebenzisa i-expander ye-liquid esikhundleni se-valve ye-air throttle air pressure.Inzuzo yayo iwukusebenzisa indlela yokupholisa yokukhulisa uketshezi kanye nokukhiqiza amandla okunwetshwa ukuze kuzuzwe inhloso yokonga amandla, ngokuvamile kungazuza ukonga amandla okungaba ngu-2%, kodwa ukutshalwa kwezimali kwayo kwamayuan ayizigidi eziyishumi.

Isistimu ye-distillation tower

Umbhoshongo 1.5 ∽ Izinga le-50000 usebenzisa umbhoshongo wepuleti le-sieve lingaphezulu, ipuleti lokujikeleza ngaphansi kombhoshongo webanga le-15000 ububanzi bombhoshongo kunezinzuzo ezengeziwe (ukugeleza koketshezi kuyi-convection yinde, kodwa ukwenza inkimbinkimbi), i-convection engaphansi kwezinga le-30000 isicelo ngaphezulu, ibanga elingaphezu kuka-15000 libusa, Ukuchichima okune ngaphezu kombhoshongo wezinga le-30000 kunamandla, umbhoshongo ogcwele amandla aphansi, kodwa ukuphakama kombhoshongo ukwandisa amamitha angu-5.Ukuhlukaniswa komoya ngaphezu kwebanga eliyizinkulungwane ezingama-50 kunenzuzo enkulu, ikakhulukazi lapho imibhoshongo engaphezulu nephansi ihlelwa ngokufana.

Umbhoshongo wokupakisha usetshenziselwa ikholomu engenhla, ikholomu ye-argon eqinile kanye nekholomu ye-argon emihle.Umkhiqizi ngokuvamile ngu-Sulzer noma u-Tianda Beiyang.Umthombo obandayo wekholomu ye-argon eqinile ngokuvamile umoya owuketshezi onothile komoyampilo, futhi igesi engcolile ingakhishelwa epayipini le-nitrogen elingcolile, ngakho ukusetshenziswa kwamandla kuba kuncane lapho isistimu ye-argon imiswa.Umthombo wokushisa wekholomu ye-argon uwumoya owuketshezi ogcwele umoya-mpilo noma i-nitrogen kukholomu engezansi, futhi umthombo obandayo ungaba umoya ongenamanzi noma i-nitrogen ewuketshezi.Isiphakeli singaba yisigaba se-liquid noma isigaba segesi.Kumele kuqashelwe ukuthi izidingo zokuvala uhlobo lwepuleti ye-crude argon tower condenser ziphakeme, ngaphandle kwalokho kuzoholela emikhiqizweni ye-argon engafaneleki.

Ukupholisa okuyinhloko kunongqimba olulodwa, ungqimba oluphindwe kabili oluqondile, ungqimba olukabili oluvundlile, ungqimba oluthathu olume mpo kanye nokupholisa okuyinhloko kwefilimu ewayo (umoya-mpilo owuketshezi nomoya-mpilo wegesi phansi, nokugeleza kwenitrogen).

Uhlelo lokucindezela umkhiqizo

Ukungena kwe-nitrogen kungahlangabezana nomoya ocindezelwe ojwayelekile, umfutho we-nitrogen turbine compressor uphezulu, uhlobo lwegiya lungonga kakhulu amandla.

I-oksijeni idlula ngokomugqa we-cylinder pressure eyodwa (ingcindezi ephansi) namasilinda amabili (umfutho ophezulu kanye nesilinda somfutho ophansi) (ukucindezela kwezinga le-8 kuya kumabha angama-30), ngokuvamile ngaphansi kwama-30 barg, udinga ukusetha igesi yokuvala i-5 barg ( I-nitrogen ingcindezi ingahlangana), ngesikhathi esifanayo, ngenxa yomoya-mpilo ophakathi kokushisa okuphezulu kwe-high pressure HuoHuan izizathu, yonke ingxenye yokugeleza yamukela ingxube yethusi, udinga ukusetha i-nitrogen yokuphepha, ngokuvamile ngokucatshangelwa komklamo wobunjiniyela;Intengo yokungena komoyampilo engenisiwe iphezulu, cishe izikhathi ezi-2 kunezasekhaya, ngokuvamile ayisetshenziswa, okwamanje ngokuvamile wonke ama-hanged oxygen oxygenation, i-discharge pressure 3∽30barG, ukugeleza okungu-8000Nm³/h ngenhla kungahlangatshezwana nayo.Nokho, izinga lokugeleza lincane futhi ukusebenza kahle komoyampilo kuphansi, ngokuvamile ku-8000Nm³/h (55%) ∽80000Nm³/h (68%).

Okujwayelekile kusetshenziselwa inqubo yokucindezelwa komoya-mpilo, kusuka ku-3 ∽ 30 barg, kepha imvamisa ngenqubo yokucindezela yangaphakathi ye-booster (ngokuvamile ukusebenza kahle okungaphezulu kuka-70%, futhi kunemikhawulo yethrafikhi, ukusebenza kahle kuphakeme kunomoya-mpilo ngamaphoyinti angaphezu kwe-10, ingakwazi ngisho nokunciphisa ukucindezelwa okuncane ekucindezelweni ngemva kokushisa inzuzo yokulahlekelwa kwamandla engeziwe, kodwa ukucindezela kwangaphakathi kwengcindezi yensimbi kudingeka kuthuthuke, ukuze kugwenywe ukushintshashintsha kwesistimu yokushintshanisa ukushisa) kuqhathaniswa, futhi ukusetshenziswa kwamandla ngemva kokunqunywa kwepulani. .

Yiziphi izinkampani ezihlonishwayo kulo mkhakha?

Itholakala e-hangzhou fuyang h igesi endaweni yokuthuthukiswa kwezomnotho nezobuchwepheshe ye-zhejiang isayensi nobuchwepheshe co., LTD iyingcweti ebambe iqhaza ocwaningweni nasekuthuthukisweni kwemishini yegesi yezimboni, ukukhiqiza nokuphatha njengenye yamabhizinisi, inkampani inesikhungo se-r&d, isikhungo senkonzo yokukhiqiza nokumaketha, abasebenzi abasezingeni eliphezulu nabachwepheshe, ukuhlinzeka amakhasimende ngokubonisana kwezobuchwepheshe, ukuklama kohlelo, ukukhiqizwa kwemikhiqizo, ukuqeqeshwa kwabasebenzi, ukufakwa, ukulungisa amaphutha nezinye izinsizakalo.
