HANGZHOU NUZHUO TECHNOLOGY GROUP CO., LTD.

Tekinoroji yekuparadzanisa mhepo ine cryogenic yakadzika inzira inoparadzanisa zvinhu zvikuru (nitrogen, oxygen neargon) mumhepo kuburikidza nekupisa kwakaderera. Inoshandiswa zvakanyanya mumaindasitiri akadai sesimbi, makemikari, mishonga uye zvemagetsi. Nekuwedzera kuri kuita magasi, kushandiswa kwetekinoroji yekuparadzanisa mhepo ine cryogenic yakadzika kuri kuramba kuchipararira. Chinyorwa chino chichakurukura zvakadzama maitiro ekugadzira mhepo ine cryogenic yakadzika, kusanganisira musimboti wayo wekushanda, michina mikuru, matanho ekushanda uye mashandisirwo ayo mumaindasitiri akasiyana-siyana.

Pfupiso yeCryogenic Air Separation Technology

Nheyo huru yekuparadzanisa mhepo ine cryogenic ndeyekutonhodza mhepo kusvika patembiricha yakaderera zvakanyanya (kazhinji iri pasi pe -150°C), kuitira kuti zvikamu zviri mumhepo zvigone kupatsanurwa zvichienderana nenzvimbo dzazvo dzakasiyana dzekufashaira. Kazhinji, unit yekuparadzanisa mhepo ine cryogenic inoshandisa mhepo sechinhu chisina kubikwa uye inopfuura nenzira dzakadai sekudzvanya, kutonhora, uye kuwedzera, pakupedzisira ichiparadzanisa nitrogen, oxygen, uye argon kubva mumhepo. Iyi tekinoroji inogona kugadzira magasi akachena zvakanyanya uye, nekudzora nemazvo ma process parameters, inosangana nezvinodiwa zvakasimba zvemhando yegasi muminda yakasiyana yemaindasitiri.

Chigadziko chemhepo chinoparadzanisa mhepo chinonzi cryogenic air separation chakakamurwa kuita zvikamu zvitatu zvikuru: air compressor, air pre-cooler, uye cold box. Air compressor inoshandiswa kudzvanya mhepo kusvika pakumanikidzwa kwakanyanya (kazhinji 5-6 MPa), pre-cooler inoderedza tembiricha yemhepo kuburikidza nekutonhodza, uye cold box ndiyo chikamu chikuru chemaitiro ese ekuparadzanisa mhepo inonzi cryogenic, kusanganisira fractionation tower, iyo inoshandiswa kuita kuti gasi riparadzaniswe.

Kudzvanywa kwemhepo uye kutonhora

Kudzvanywa kwemhepo ndiyo nhanho yekutanga mukupatsanurwa kwemhepo ine cryogenic, kunyanya kunangana nekudzvanya mhepo iri mumhepo ine kumanikidzwa kwakanyanya (kazhinji 5-6 MPa). Mushure mekunge mhepo yapinda musystem kuburikidza necompressor, tembiricha yayo inozowedzera zvakanyanya nekuda kwemaitiro ekudzvanywa. Saka, matanho akatevedzana ekutonhodza anofanira kuitwa kuderedza tembiricha yemhepo yakadzvanywa. Nzira dzakajairika dzekutonhodza dzinosanganisira kutonhodza nemvura uye kutonhodza mhepo, uye mhedzisiro yakanaka yekutonhodza inogona kuve nechokwadi chekuti mhepo yakadzvanywa haikonzeri mutoro usingakoshi pamidziyo panguva yekugadzirisa kunotevera.

Mushure mekunge mhepo yatonhodzwa pakutanga, inopinda muchikamu chinotevera chekutonhodza usati watanga. Chikamu chekutonhodza chinowanzo shandisa nitrogen kana nitrogen yemvura senzvimbo yekutonhodza, uye kuburikidza nemidziyo yekuchinjana kupisa, tembiricha yemhepo yakamanikidzwa inodzikiswa zvakanyanya, zvichigadzirira maitiro anotevera e cryogenic. Kuburikidza nekutonhodza usati watanga, tembiricha yemhepo inogona kuderedzwa kusvika padyo netembiricha yekunyungudika, zvichipa mamiriro anodiwa ekuparadzanisa zvikamu mumhepo.

Kuwedzera tembiricha yakaderera uye kupatsanurwa kwegasi

Mushure mekunge mhepo yamanikidzwa uye yatonhodzwa kare, danho rinotevera rinokosha kuwedzera tembiricha yakaderera uye kupatsanurwa kwegasi. Kuwedzera tembiricha yakaderera kunowanikwa nekuwedzera nekukurumidza mhepo yakamanikidzwa kuburikidza nevharuvhu yekuwedzera kusvika pakumanikidzwa kwakajairika. Munguva yekuwedzera, tembiricha yemhepo inodzikira zvakanyanya, kusvika patembiricha yekunyungudika. Nitrogen neokisijeni mumhepo zvinotanga kunyungudika patembiricha dzakasiyana nekuda kwekusiyana kwazvo kwenzvimbo dzekufashaira.

Mumidziyo yekuparadzanisa mhepo ine cryogenic, mhepo ine liquefied inopinda mubhokisi rinotonhora, uko shongwe yekuparadzanisa ndiyo chikamu chakakosha chekuparadzanisa gasi. Nheyo huru yeshongwe yekuparadzanisa ndeyekushandisa musiyano wepombi yekufashaira wezvikamu zvakasiyana mumhepo, kuburikidza negasi rinokwira nekudonha mubhokisi rinotonhora, kuti uwane kupatsanurwa kwegasi. Pombi yekufashaira yenitrogen i -195.8°C, iyo yeokisijeni i -183°C, uye iyo yeargon i -185.7°C. Nekugadzirisa tembiricha nekumanikidzwa mushongwe, kupatsanurwa kwegasi kunoshanda zvakanaka kunogona kuwanikwa.

Maitiro ekuparadzanisa gasi mushongwe yekuparadzanisa akanyatsojeka. Kazhinji, sisitimu yeshongwe yekuparadzanisa ine matanho maviri inoshandiswa kubvisa nitrogen, okisijeni, uye argon. Kutanga, nitrogen inoparadzaniswa muchikamu chepamusoro cheshongwe yekuparadzanisa, nepo okisijeni yemvura neargon zvakaungana muchikamu chezasi. Kuti zvivandudze kushanda kwekuparadzanisa, chinhu chinotonhorera uye chinodzoreredza mvura zvinogona kuwedzerwa mushongwe, izvo zvinogona kudzora zvakanyanya maitiro ekuparadzanisa gasi.

Nitrogen inobviswa inowanzova yakachena kwazvo (inopfuura 99.99%), inoshandiswa zvakanyanya mukugadzira simbi, indasitiri yemakemikari, uye zvemagetsi. Okisijeni inoshandiswa muindasitiri yezvekurapa, indasitiri yesimbi, uye mamwe maindasitiri anoshandisa simba rakawanda anoda okisijeni. Argon, segasi risingawanzo kuwanikwa, inowanzo bviswa kuburikidza nemaitiro ekuparadzanisa gasi, nekuchena kwakanyanya uye inoshandiswa zvakanyanya mukushongedza, kunyungudutsa, uye kucheka nelaser, pakati pemamwe minda yepamusoro-soro. Sisitimu yekudzora otomatiki inogona kugadzirisa maparamita akasiyana-siyana ekuita zvinoenderana nezvinodiwa chaizvo, kugadzirisa kushanda zvakanaka kwekugadzira, uye kuderedza kushandiswa kwesimba.

Pamusoro pezvo, kugadziriswa kwe deep cryogenic air separation system kunosanganisirawo matekinoroji ekuchengetedza simba uye emission control. Semuenzaniso, nekuwana simba rekupisa kwakaderera musystem, marara esimba anogona kuderedzwa uye kushanda nesimba kwese kwese kunogona kuvandudzwa. Uyezve, nemitemo yezvakatipoteredza iri kuramba ichioma, michina yemazuva ano ye deep cryogenic air separation iri kutarisisawo kuderedza kuburitswa kwemagasi ane njodzi uye kuwedzera hushamwari hwenzvimbo yekugadzira.

Mashandisirwo ekuparadzanisa mhepo yakadzika ye cryogenic

Tekinoroji yekuparadzanisa mhepo ine cryogenic yakadzika haingoshandisirwe chete mukugadzira magasi emaindasitiri, asiwo ine basa guru muminda yakawanda. Mumaindasitiri esimbi, fetiraiza, uye petrochemical, tekinoroji yekuparadzanisa mhepo ine cryogenic yakadzika inoshandiswa kupa magasi ane purity yakakura senge oxygen nenitrogen, zvichiita kuti maitiro ekugadzira abudirire. Muindasitiri yezvemagetsi, nitrogen inopihwa nekuparadzanisa mhepo ine cryogenic yakadzika inoshandiswa kudzora mhepo mukugadzira semiconductor. Muindasitiri yezvekurapa, oxygen ine purity yakawanda yakakosha pakutsigira kufema kwevarwere.

Pamusoro pezvo, tekinoroji yekuparadzanisa mhepo yakadzika inoburitsa chiedza ine basa rakakosha mukuchengetedza nekufambisa okisijeni yemvura nenitrogen yemvura. Mumamiriro ezvinhu apo magasi ane simba rakawanda haagone kutakurwa, okisijeni yemvura nenitrogen yemvura zvinogona kuderedza huwandu hwemhepo uye kuderedza mari yekufambisa.

Mhedziso

Tekinoroji yekuparadzanisa mhepo ine cryogenic yakadzika, ine kugona kwayo kuparadzanisa magasi kwakanyatsonaka uye kwakaringana, inoshandiswa zvakanyanya muzvikamu zvakasiyana-siyana zvemaindasitiri. Nekufambira mberi kwetekinoroji, maitiro ekuparadzanisa mhepo ine cryogenic yakadzika achava akangwara uye asingashandise simba zvakanyanya, ukuwo achivandudza kuchena kwekuparadzanisa magasi uye kushanda zvakanaka kwekugadzira. Mune ramangwana, kuvandudzwa kwetekinoroji yekuparadzanisa mhepo ine cryogenic yakadzika maererano nekuchengetedzwa kwezvakatipoteredza uye kudzoreredzwa kwezviwanikwa kuchavawo gwara guru rekusimudzira indasitiri.
