Whakawhiti LN₂: Ngā Pūnaha Whakamarumaru Korehau mō te Hauota Wai Parakore-Teitei

E tūmanakohia ana ka tino pai te mahi a ngā pūnaha whakawhiti hauota wai: kia mau te LN₂ i te makariri me te pumau mai i te tāke rokiroki ki te wāhi whakamahi. I roto i ngā taiao ahumahi tūturu, inā koa ko ngā tono hau haurua-haurua me te hau parakore teitei, ahakoa he iti noa te wera ka uru mai ka taea te hanga i te kohu, te kore pumau o te pehanga, te kore rānei o ngā tikanga rere.

At HL Cryogenics, ka hoahoa mātoupaipa whakamahana korehaumengongo ngāwaringā pūnaha motuhake mō te whakawhiti LN₂ tawhiti me te iti o te ngaronga wera. Mā te whakakotahi i te whakamarumaru korehau e tiakina ana,ngā takirere whakamātao korehau, mehangarau wehenga ā-wāhanga, ka taea e ā mātou pūnaha te pupuri i te tuku wai kotahi-wāhanga pumau puta noa i ngā whatunga tohatoha cryogenic matatini.

He aha te Hiranga o te Whakamarumaru Korehau mō te Whakawhiti LN₂

Ka mahi te hauota wai i te -196 °C pea. Mēnā he maha ngā pāmahana kei runga ake i te 25 °C, ka taea e te rerekētanga pāmahana puta noa i te pakitara paipa te neke atu i te 200 °C. Ki te kore he ārai pai, ka tere te uru o te wera ki roto i te pūnaha mā te kawe hiko, te whakawhiti hiko, me te irahiko, ka puta he hau kohua me te rere rua-wāhanga kore pumau.

Tō mātoupaipa whakamahana korehauKa whakamahia e ngā pūnaha he hanganga maitai kore waikura pakitara-rua me te wāhi porowhita korehau-teitei e puritia ana i raro i te 1 × 10⁻⁵ mbar. I raro i tēnei āhuatanga, kua tata te whakakore i te kawe hau me te kawe hiko. Ka whakaitihia anō e te whakamarumaru paparanga maha (MLI) te whakawhiti wera hihi mā te whakaata i te kaha whero-whero mai i te paipa makariri o roto.

Ki te whakatauritea ki te whakamahana pahuka tuku iho, he iti iho te kawe wera whai hua, e āhei ai te whakawhiti i te LN₂ ki ngā rau mita me te pupuri tonu i te āhua wai me te pēhanga pumau.

Pūnaha Papu Korehau Hihirimō te pumau mō te wā roa

Ko tētahi o ngā take noa i roto i te whakamahana cryogenic ko te pirau haere o te korehau i roto i te wā. Ko te putanga hau mai i ngā mata maitai kore waikura, ngā rauemi whakamahana, me te urunga iti o te hau ka piki haere te pēhanga porowhita, ka whakaiti i te mahi wera.

Hei whakatika i tēnei,HL Cryogenicswhakauru ana i tētahiPūnaha Papu Korehau Hihiriki roto i te whatunga whakawhiti. Ka whakawātea tonu, ka whakawātea rānei te pūnaha i te wāhi porowhita i ia wā, i ia wā rānei, kia mau tonu ai te pumau o te korehau puta noa i te mahi roa.

Ko te tikanga kei roto i te waeine korehau:

• Ngā papu korehau panuku maroke, ngā papu korehau turbomolecular rānei
• Ngā ine aroturuki korehau
• Ngā waeine mimiti tātari ngota
• Ngā takirere wehe me te kore-hoki

Mā tēnei huarahi tiaki korehau kaha ka noho rite tonu te mahi whakamahana mō ngā tau maha e mahi ana, ā, he mea tino nui tēnei i roto i ngā whare haurua-waea ina pā tika te pumau o te pāmahana LN₂ ki te auautanga o te tukanga.

Tukunga Wāhanga-Kotahi Pūmau meNgā Takirere Whakamarumaru KorehaumeNgā Wehewehe Wāhanga

I roto i ngā pūnaha whakawhiti cryogenic, he mea nui te pupuri i te rere o te wai kotahi-wāhanga. Ka taea e ngā putunga kohu i roto i te paipa te arahi ki te rere kore pumau, te pakaru, te piki me te heke o te pono o te tukanga.

Tō mātoungā takirere whakamātao korehaukua hangaia me ngā potae kua hipokina ki te korehau hei whakaiti i te urunga wera ā-rohe huri noa i te tinana takirere. Kei waho o te rohe cryogenic te takai kakau hei ārai i te hukapapa me te whakarite kia pono te mahi i te wā e huri haere ana.

I raro iho,ngā wehewehe wāhanga kua whakamahanatia ki te korehautangohia te kohu i roto i te whakawhiti. Ka tomo a LN₂ ki te wehewehe mā te taha whakarara, kia taea ai e ngā āhua hau me te wai te wehe pai i mua i te rere tonu o te wai ki raro.

Mā tēnei huinga ka mau tonu te pēhanga, ā, ka whakarite hoki ka whiwhi ngā taputapu o raro i te hauota wai ma, kua whakamatao rawa.

Whakaurunga Tanki Iti mō ngā Whatunga LN₂ Tohatoha

Mō ngā whare he rerekē te tono, he maha rānei ngā teihana whakamahi, ka taea e te parenga waenga te whakapai ake i te pumau o te pūnaha.

Tō mātouRaupapa Tank Iti, mai i te 100 rita ki te 3 000 rita, e whakarato ana i te rokiroki LN₂ ā-rohe e tata ana ki ngā taputapu tukatuka. Ka whakamahia e ia tāke he whakamarumaru korehau me ngā tautoko ā-roto iti-te-kawe hei whakaiti i te pēhanga-ake me te ngaronga wera.

I roto i ngā mahi whaihua, ka āwhina ngā Tanki Iti:

• Mimihia ngā rerekētanga pēhanga
• Whakahaerehia ngā wā tino kai
• Whakaitihia te kawenga i runga i te pūnaha tuku matua
• Whakapai ake i te pumau tata ki ngā taputapu tairongo

E whakamahia whānuitia ana tēnei whirihoranga i roto i ngā whare hanga haurua-haurua, ngā taiwhanga, me ngā pūnaha tohatoha hau ahumahi.

Te Mahi Pūnaha me te Hoahoa Hangarau

He mea noaHL CryogenicsKa whakahaerehia te pūnaha whakawhiti LN₂ i waenga i te 3 me te 10 pae me ngā tere rere tae atu ki te 8 m/s.

Pūmaupaipa whakamahana korehaue whakamahia ana mō ngā oma roa, ko te tikangangāwari whakamātao korehauKa tāutahia ngā wāhanga ngongo ki ngā hononga taputapu, ki ngā hononga whānui, ki ngā wāhi rānei e hiahia ana kia whakatikatikaina te nekehanga.

I raro i ngā āhuatanga mahi pumau, ka taea te whakaiti i te turuturu wera whānui ki te 0.25–0.5 W/m i runga i te whirihoranga raina. I roto i te maha o ngā kaupapa, ka taea e te hauota wai te haere i roto i ngā rau mita me te kore e puta he kohu.

Ko ngā wāhanga ngongo ngāwari e whakamahi ana i ngā matua o roto o te maitai kore waikura 316L me ngā whiri whakakaha o waho hei ātete ki te pēhanga me te roa o te ora mahi.

Te Whakamahinga o te Hanganga Ārai i Āhia ki te Rawhiti

I whakahoutia e tētahi kaihanga haurua-ā-ringa i Taiwana tana pūnaha tohatoha LN₂ whai muri i te pānga o te kore pumau o te kohu i roto i ngā paipa kua whakamahanahia ā-mīhini.

HL Cryogenicsi tukuna he otinga whakawhiti ranu kei roto ko:

• Paipa whakamahana korehaumō te ara tohatoha matua
• Ngongo ngāwari kua whakamahanatia ki te korehaui ngā pūwāhi hononga taputapu
• Pokapūte papu korehau hihiri
• Ngā wehewehe wāhanga kua whakamahanatia ki te korehaui ia wāhi whakaputa

Whai muri i te tāutanga, i tau te turuturu wera o te pūnaha i inehia ki te 0.27 W/m pea, ā, i whakakorea e te whare ngā aukati whakaputa e pā ana ki te LN₂ i te wā e mahi tonu ana.
