HANGZHOU NUZHUO TECHNOLOGY GROUP CO., LTD.

Ukadaulo wakuzama wa cryogenic wolekanitsa mpweya ndi njira yomwe imalekanitsa zigawo zazikulu (nayitrogeni, oxygen ndi argon) mumlengalenga kudzera mu kutentha kochepa. Amagwiritsidwa ntchito kwambiri m'mafakitale monga zitsulo, mankhwala, mankhwala ndi zamagetsi. Pakuchulukirachulukira kwa mpweya, kugwiritsa ntchito ukadaulo wolekanitsa mpweya wa cryogenic kukuchulukirachulukira. Nkhaniyi ifotokoza mwatsatanetsatane za kupanga kwakuya kwa mpweya wa cryogenic, kuphatikizapo mfundo yake yogwirira ntchito, zipangizo zazikulu, masitepe opangira ntchito ndi ntchito yake m'mafakitale osiyanasiyana.

Zambiri za Cryogenic Air Separation Technology

Mfundo yaikulu ya kupatukana kwa mpweya wa cryogenic ndi kuziziritsa mpweya ku kutentha kwambiri (nthawi zambiri pansi -150 ° C), kotero kuti zigawo za mlengalenga zitha kupatulidwa molingana ndi malo awo otentha. Nthawi zambiri, gawo lolekanitsa mpweya wa cryogenic limagwiritsa ntchito mpweya ngati zopangira ndipo limadutsa njira monga kuponderezana, kuzizira, ndi kukulitsa, potsirizira pake kulekanitsa nayitrogeni, mpweya, ndi argon kuchokera mumlengalenga. Ukadaulo uwu ukhoza kutulutsa mpweya woyeretsedwa kwambiri ndipo, powongolera ndendende magawo azinthu, amakwaniritsa zofunikira zamtundu wa gasi m'mafakitale osiyanasiyana.

Chigawo cholekanitsa mpweya wa cryogenic chimagawidwa m'magawo atatu: air compressor, air pre-cooler, ndi cold box. Mpweya wamagetsi umagwiritsidwa ntchito kukakamiza mpweya kuti ukhale wothamanga kwambiri (nthawi zambiri 5-6 MPa), chozizira chisanadze chimachepetsa kutentha kwa mpweya kupyolera mu kuzizira, ndipo bokosi lozizira ndilo gawo lalikulu la ndondomeko yonse yolekanitsa mpweya wa cryogenic, kuphatikizapo nsanja yogawanitsa, yomwe imagwiritsidwa ntchito kukwaniritsa kupatukana kwa mpweya.

Kuponderezana kwa mpweya ndi kuziziritsa

Kuponderezana kwa mpweya ndiye gawo loyamba pakulekanitsa kwa mpweya wa cryogenic, makamaka cholinga cha kuponderezana kwa mpweya mumlengalenga kuti ukhale wolimba kwambiri (nthawi zambiri 5-6 MPa). Mpweya ukalowa m'dongosolo kudzera mu compressor, kutentha kwake kudzawonjezeka kwambiri chifukwa cha ndondomeko yopondereza. Choncho, njira zingapo zoziziritsa ziyenera kuchitidwa kuti muchepetse kutentha kwa mpweya wopanikizika. Njira zoziziritsa zodziwika bwino zimaphatikizapo kuziziritsa kwa madzi ndi kuziziritsa kwa mpweya, ndipo kuziziritsa kwabwino kumatha kuonetsetsa kuti mpweya woponderezedwa suyambitsa katundu wosafunika pazida pakukonza kotsatira.

Mpweya ukakhala utakhazikika, umalowa mu gawo lotsatira la kuzizira. Gawo lozizira lisanayambe nthawi zambiri limagwiritsa ntchito nayitrogeni kapena nayitrogeni wamadzimadzi ngati njira yozizirira, ndipo kudzera mu zida zosinthira kutentha, kutentha kwa mpweya woponderezedwa kumachepetsedwanso, kukonzekera njira yotsatira ya cryogenic. Kupyolera mu kuziziritsa kusanachitike, kutentha kwa mpweya kumatha kuchepetsedwa kufupi ndi kutentha kwa liquefaction, kupereka zinthu zofunika pakulekanitsa zigawo zikuluzikulu mumlengalenga.

Kukula kwapang'onopang'ono komanso kulekanitsa gasi

Mpweya ukakanikizidwa ndikuzimitsidwa kale, gawo lotsatira lofunikira ndikukulitsa kutentha kwapang'onopang'ono komanso kulekanitsa gasi. Kuwonjezeka kwa kutentha kwapansi kumatheka mwa kukulitsa mofulumira mpweya woponderezedwa kupyolera mu valve yowonjezera ku kuthamanga kwabwino. Panthawi yowonjezereka, kutentha kwa mpweya kumatsika kwambiri, kufika kutentha kwa liquefaction. Nayitrojeni ndi okosijeni m'mlengalenga zimayamba kusungunuka pa kutentha kosiyanasiyana chifukwa cha kusiyana kwawo.

Mu zida zolekanitsa mpweya wa cryogenic, mpweya wamadzimadzi umalowa m'bokosi lozizira, pomwe nsanja yogawa ndi gawo lofunikira pakulekanitsa gasi. Mfundo yaikulu ya nsanja yogawanitsa ndikugwiritsa ntchito kusiyana kwa malo otentha a zigawo zosiyanasiyana mumlengalenga, kupyolera mu mpweya wokwera ndi kugwa mu bokosi lozizira, kuti mukwaniritse kulekanitsa gasi. Kuwira kwa nayitrogeni ndi -195.8 ° C, oxygen ndi -183 ° C, ndipo ya argon ndi -185.7 ° C. Mwa kusintha kutentha ndi kupanikizika mu nsanja, kulekanitsa bwino gasi kungapezeke.

Njira yolekanitsa gasi mu nsanja yogawa ndi yolondola kwambiri. Nthawi zambiri, njira yogawa magawo awiri imagwiritsidwa ntchito potulutsa nayitrogeni, mpweya, ndi argon. Choyamba, nayitrogeni imasiyanitsidwa kumtunda kwa nsanja yogawa, pomwe mpweya wamadzimadzi ndi argon zimakhazikika m'munsi. Kupititsa patsogolo kulekanitsa bwino, choziziritsa kuzizira ndi re-evaporator zitha kuwonjezeredwa munsanja, zomwe zimatha kuwongolera bwino njira yolekanitsa gasi.

Nayitrogeni wotengedwa nthawi zambiri amakhala oyera kwambiri (pamwamba pa 99.99%), omwe amagwiritsidwa ntchito kwambiri muzitsulo, makampani opanga mankhwala, ndi zamagetsi. Oxygen imagwiritsidwa ntchito m'zachipatala, mafakitale achitsulo, ndi mafakitale ena omwe amagwiritsa ntchito mphamvu zambiri zomwe zimafuna mpweya. Argon, monga mpweya wosowa, nthawi zambiri amatengedwa kudzera mu njira yolekanitsa mpweya, ndi chiyero chapamwamba komanso chogwiritsidwa ntchito kwambiri powotcherera, kusungunula, ndi kudula laser, pakati pa minda ina yapamwamba. Makina owongolera okha amatha kusintha magawo osiyanasiyana malinga ndi zosowa zenizeni, kukhathamiritsa kupanga bwino, ndikuchepetsa kugwiritsa ntchito mphamvu.

Kuphatikiza apo, kukhathamiritsa kwa njira yakuzama yolekanitsa mpweya wa cryogenic kumaphatikizanso matekinoloje opulumutsa mphamvu ndi utsi. Mwachitsanzo, pakubwezeretsanso mphamvu zocheperako m'dongosolo, kuwononga mphamvu kumatha kuchepetsedwa ndipo mphamvu yonse yogwiritsira ntchito mphamvu imatha kuwongolera. Kuphatikiza apo, ndi malamulo okhwima a chilengedwe, zida zamakono zolekanitsa mpweya wa cryogenic zikuwunikanso kwambiri kuchepetsa mpweya woipa komanso kupititsa patsogolo kuyanjana kwa chilengedwe pakupanga.

Ntchito zakuya cryogenic mpweya kulekana

Ukadaulo wozama wolekanitsa mpweya wa cryogenic sikuti umangokhala ndi ntchito zofunika kwambiri popanga mpweya wamakampani, komanso umagwira ntchito yofunika kwambiri m'magawo angapo. M'mafakitale azitsulo, feteleza, ndi petrochemical, ukadaulo wakuzama wa cryogenic wolekanitsa mpweya umagwiritsidwa ntchito popereka mpweya wabwino kwambiri monga mpweya ndi nayitrogeni, kuwonetsetsa kuti njira zopangira zikuyenda bwino. M'makampani amagetsi, nayitrogeni woperekedwa ndi kulekanitsidwa kwa mpweya wa cryogenic amagwiritsidwa ntchito pakuwongolera mpweya popanga semiconductor. M'makampani azachipatala, mpweya wabwino kwambiri ndi wofunikira kwambiri pakuthandizira kupuma kwa odwala.

Kuphatikiza apo, ukadaulo wakuya wa cryogenic wolekanitsa mpweya umagwiranso ntchito yofunika kwambiri pakusungirako komanso kunyamula mpweya wamadzimadzi ndi nayitrogeni wamadzimadzi. M'malo omwe mpweya wothamanga kwambiri sungathe kunyamulidwa, okosijeni wamadzimadzi ndi nayitrogeni wamadzimadzi amatha kuchepetsa kuchuluka kwake komanso kutsika mtengo wamayendedwe.

Mapeto

Ukadaulo wakuzama wa cryogenic wolekanitsa mpweya, wokhala ndi mphamvu zolekanitsa bwino komanso zolondola, umagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana. Ndi kupita patsogolo kwaukadaulo, njira yakuzama yolekanitsa mpweya wa cryogenic idzakhala yanzeru komanso yopatsa mphamvu, pomwe ikukulitsa kuyera kwa kulekanitsa gasi komanso kupanga bwino. M'tsogolomu, luso laukadaulo losiyanitsa mpweya wa cryogenic pankhani yachitetezo cha chilengedwe ndi kubwezeretsanso zinthu kudzakhalanso chitsogozo chofunikira pakukula kwamakampani.
