HANGZHOU NUZHUO TECHNOLOGY GROUP CO.,LTD.

Iyo yakadzika cryogenic air separation technology inzira inoparadzanisa zvikamu zvikuru (nitrogen, oxygen uye argon) mumhepo kuburikidza nekupisa kwakadzika. Inoshandiswa zvakanyanya mumaindasitiri akadai sesimbi, makemikari, mishonga uye zvemagetsi. Nekuwedzera kuri kudiwa kwemagasi, kushandiswa kweiyo yakadzika cryogenic mhepo yekuparadzanisa tekinoroji iri kuramba ichipararira. Ichi chinyorwa chichanyatso kurukura nezvekugadzirwa kwezvakadzama cryogenic kupatsanurwa kwemhepo, kusanganisira iyo yekushanda kwayo, midziyo huru, matanho ekushanda uye kushandiswa kwayo mumaindasitiri akasiyana-siyana.

Mhedziso yeCryogenic Air Separation Technology

Nheyo yekutanga yekuparadzaniswa kwemhepo ye cryogenic ndeyekutonhodza mhepo kusvika kune yakanyanya kuderera tembiricha (kazhinji pazasi -150 ° C), kuitira kuti zvikamu zviri mumhepo zvipatsanurwe zvinoenderana nekusiyana kwavo kwekubikira. Kazhinji, iyo cryogenic air separation unit inoshandisa mhepo seyakagadzirwa uye inofamba nenzira dzakadai sekumanikidza, kutonhora, uye kuwedzera, pakupedzisira kuparadzanisa nitrogen, oksijeni, uye argon kubva mumhepo. Iyi tekinoroji inogona kuburitsa yakakwira-kuchena magasi uye, nekunyatso kudzora maitiro paramita, inosangana nezvinodiwa zvakasimba zvemhando yegasi munzvimbo dzakasiyana dzeindasitiri.

Iyo cryogenic air separation unit yakakamurwa kuita zvikamu zvitatu zvikuru: air compressor, air pre-cooler, uye inotonhora bhokisi. Iyo compressor yemhepo inoshandiswa kudzvanya mhepo kune yakanyanya kudzvanywa (kazhinji 5-6 MPa), iyo pre-inotonhorera inoderedza tembiricha yemhepo kuburikidza nekutonhodza, uye inotonhora bhokisi ndiyo yakakosha chikamu chese cryogenic mhepo yekuparadzanisa maitiro, kusanganisira iyo fractionation shongwe, iyo inoshandiswa kuwana gasi kupatsanurwa.

Air compression uye kutonhora

Kutsikirirwa kwemhepo ndiyo nhanho yekutanga mukuparadzaniswa kwemhepo ye cryogenic, kunyanya iine chinangwa chekumanikidza mhepo pamhepo yekumanikidza kune yakanyanya kumanikidza (kazhinji 5-6 MPa). Mushure mokunge mhepo inopinda muhurongwa kuburikidza ne compressor, kutonhora kwayo kuchawedzera zvakanyanya nekuda kwekugadzirisa. Naizvozvo, nhevedzano yematanho ekutonhodza inofanira kuitwa kudzikisa tembiricha yemhepo yakamanikidzwa. Nzira dzekutonhodza dzakajairika dzinosanganisira kutonhora kwemvura uye kutonhora kwemhepo, uye kutonhora kwakanaka kunogona kuve nechokwadi kuti mweya wakamanikidzwa haukonzeri mutoro usingakoshi pamidziyo panguva yekuzogadzirisa.

Mushure mekunge mhepo yatanga kutonhora, inopinda muchikamu chinotevera chekutonhora kwekutanga. Iyo pre-kutonhora nhanho inowanzo shandisa nitrogen kana yemvura nitrogen senge inotonhorera, uye kuburikidza nekupisa kupisa midziyo, tembiricha yemhepo yakamanikidzwa inowedzera kuderedzwa, kugadzirira inotevera cryogenic process. Kuburikidza ne-pre-cooling, kutonhora kwemhepo kunogona kuderedzwa kusvika pedyo nekupisa kwe liquefaction, kupa mamiriro ezvinhu anodiwa ekuparadzaniswa kwezvikamu mumhepo.

Kuwedzera-kupisa kwekuwedzera uye kuparadzaniswa kwegasi

Mushure mekunge mhepo yakamanikidzwa uye isati yatonhodzwa, danho rinotevera rinokosha nderokuwedzera-kupisa uye kupatsanurwa kwegasi. Kuwedzera kwekushisa kwepasi kunowanikwa nekukurumidza kuwedzera mhepo yakamanikidzwa kuburikidza nevhavha yekuwedzera kune yakajairika kumanikidzwa. Munguva yekuwedzera, tembiricha yemhepo inodonha zvakanyanya, ichisvika pakupisa kwe liquefaction. Nitrojeni neokisijeni mumhepo zvinotanga kunyungudika patembiricha dzakasiyana nekuda kwekusiyana kwadzo.

Mune cryogenic mhepo yekuparadzanisa midziyo, iyo liquefied mweya inopinda mubhokisi rinotonhora, uko shongwe yekuparadzanisa ndiyo chikamu chakakosha chekuparadzanisa gasi. Musimboti wemusimboti weshongwe yekupatsanura ndeye kushandisa iyo yekubirira misiyano yezvikamu zvakasiyana mumhepo, kuburikidza negasi rinokwira nekudonha mubhokisi rinotonhora, kuwana kupatsanurwa kwegasi. Kuvira kwe nitrogen i -195.8°C, iyo yeoxygen i -183°C, uye iyo yeargon i -185.7°C. Nekugadzirisa kutonhora uye kudzvinyirira mushongwe, kupatsanurwa kwakanaka kwegasi kunogona kuwanikwa.

Iyo gasi kupatsanurwa maitiro mufractionation tower yakanyatsojeka. Kazhinji, nhanho mbiri-nhanho yekuparadzanisa tower system inoshandiswa kubvisa nitrogen, oxygen, uye argon. Chekutanga, nitrogen inopatsanurwa muchikamu chepamusoro cheshongwe yekuparadzanisa, nepo okisijeni yemvura uye argon zvakanyungudutswa muchikamu chepasi. Kuti uvandudze kushanda kwekuparadzanisa, inotonhorera uye re-evaporator inogona kuwedzerwa mushongwe, iyo inogona kunyatso kudzora maitiro ekuparadzanisa gasi.

Iyo nitrogen yakabviswa inowanzo kuchena kwepamusoro (pamusoro pe99.99%), inoshandiswa zvakanyanya musimbi, indasitiri yemakemikari, uye zvemagetsi. Okisijeni inoshandiswa mukurapa, indasitiri yesimbi, uye mamwe maindasitiri anoshandisa simba zvakanyanya anoda oxygen. Argon, segasi risingawanzo, rinowanzo kutorwa kuburikidza negasi kupatsanurwa maitiro, nekuchena kwepamusoro uye kushandiswa zvakanyanya mukupisa, kunyungudika, uye kucheka kwelaser, pakati pemamwe minda yepamusoro. Iyo otomatiki yekudzora sisitimu inogona kugadzirisa akasiyana maitiro ma paramita zvinoenderana nezvinodiwa chaizvo, optimize kugadzira kugadzirwa, uye kuderedza kushandiswa kwesimba.

Uye zvakare, iyo optimization yeyakadzika cryogenic air separation system inosanganisirawo ekuchengetedza simba uye emission control tekinoroji. Semuenzaniso, nekudzoreredza iyo yakaderera-tembiricha simba muhurongwa, kupera kwesimba kunogona kudzikiswa uye kugona kwese kwesimba rekushandisa kunogona kuvandudzwa. Zvakare, nekuwedzera kuomesera mirau yezvakatipoteredza, yazvino yakadzika cryogenic mhepo yekuparadzanisa michina iri kubhadhara zvakanyanya kudzikisa inokuvadza gasi kuburitswa uye kuwedzera hushamwari hwezvakatipoteredza hwekugadzira maitiro.

Zvikumbiro zveyakadzika cryogenic kupatsanurwa kwemhepo

Deep cryogenic air separation tekinoroji haina kungoita zvakakosha maapplication mukugadzirwa kwemaindasitiri magasi, asiwo inoita basa rakakosha muminda yakawanda. Mumaindasitiri esimbi, fetiraiza, uye petrochemical, yakadzika cryogenic mhepo yekuparadzanisa tekinoroji inoshandiswa kupa yakakwira-kuchena magasi akadai seokisijeni nenitrogen, kuve nechokwadi maitiro ekugadzira anoshanda. Muindasitiri yemagetsi, iyo nitrogen inopihwa neyakadzama cryogenic mhepo kupatsanurwa inoshandiswa kudzora mhepo mukugadzira semiconductor. Muindasitiri yezvokurapa, yakakwira-kuchena okisijeni kwakakosha kune varwere kutsigira kufema.

Uye zvakare, yakadzika cryogenic mhepo yekuparadzanisa tekinoroji inoitawo basa rakakosha mukuchengetedza uye kutakura kwemvura okisijeni uye mvura nitrogen. Mumamiriro ezvinhu apo magasi epamusoro-soro asingakwanisi kutakurwa, okisijeni yemvura uye mvura nitrogen inogona kuderedza zvakanyanya huwandu uye kuderedza mari yekufambisa.

Mhedziso

Iyo yakadzika cryogenic mhepo yekuparadzanisa tekinoroji, iine inoshanda uye chaiyo gasi kupatsanura kugona, inoshandiswa zvakanyanya munzvimbo dzakasiyana dzeindasitiri. Nekufambira mberi kwetekinoroji, iyo yakadzika cryogenic mhepo yekuparadzanisa maitiro ichave yakangwara uye ine simba-inoshanda, uku ichiwedzera kuchena kwekuparadzaniswa kwegasi uye kugona kugadzira. Mune ramangwana, kuvandudzwa kweiyo yakadzika cryogenic mhepo yekuparadzanisa tekinoroji maererano nekuchengetedzwa kwezvakatipoteredza uye kudzoreredza zviwanikwa kuchavawo gwara rakakosha rekusimudzira indasitiri.
