HANGZHOU NUZHUO TECHNOLOGY GROUP CO.,LTD.

Liquid nitrogen, ine kemikari formula N₂, imvura isina ruvara, isina kunhuhwirira, uye isina muchetura inowanikwa nekunyungudutsa nitrogen kuburikidza nekutonhora kwakadzika. Inoshandiswa zvakanyanya mukutsvagisa kwesainzi, mushonga, indasitiri, uye kutonhora kwechikafu nekuda kwekudzikira kwayo kupisa uye kushandiswa kwakasiyana. Saka, mvura nitrogen inoumbwa sei? Chinyorwa ichi chinopa mhinduro yakadzama kumubvunzo uyu kubva kune akati wandei: kudhirowa kwenitrogen, iyo yakadzika yekutonhodza mweya yekuparadzanisa nzira, maitiro ekugadzira nitrogen yemvura, uye mashandisirwo ayo anoshanda.

Kubvisa nitrojeni

Kugadzirwa kwenitrogen yemvura kunoda danho rekutanga rekuwana pure nitrogen. Nitrogen ndicho chikamu chikuru chemhepo yePasi, inoverengera 78% yehuwandu hwemhepo. Kubvisa nitrogen kunowanzoitwa uchishandisa yakadzika inotonhora mhepo yekuparadzanisa tekinoroji kana kumanikidza swing adsorption (PSA) nzira. Kuparadzaniswa kwemhepo inotonhora yakadzika ndiyo inonyanya kushandiswa nzira yeindasitiri. Nekudzvanya nekutonhodza mhepo, inoparadzanisa okisijeni, nitrogen, uye zvimwe zvikamu zvegasi patembiricha dzakasiyana. Iyo yekumanikidza swing adsorption nzira inoshandisa akasiyana adsorption zvimiro zveadsorbents kune akasiyana magasi, kuwana yakakwira-kuchena nitrogen kuburikidza nedenderedzwa readsorption uye desorption. Idzi nzira dzinoona kuchena uye mhando yenitrogen seyakagadziriswa yemvura yekugadzira nitrogen.

Deep cold air separation method

Iyo yakadzika inotonhora yemhepo yekuparadzanisa nzira ndeimwe yematanho akakosha mukugadzirwa kwemvura nitrogen. Iyi nzira inoshandisa nzvimbo dzakasiyana dzekufashaira dzemagasi ari mumhepo kunyungudutsa uye zvishoma nezvishoma kubudisa nitrogen, oxygen, uye zvimwe zvikamu zvegasi. Nzvimbo yekuvira yenitrogen ndeye -195.8 ℃, nepo iyo yeokisijeni iri -183 ℃. Nekudzikisa tembiricha zvishoma nezvishoma, okisijeni inotanga kunyungudutswa uye yakaparadzaniswa nemamwe magasi, ichisiya chikamu chasara seyepamusoro-kuchena nitrogen. Zvino, iyi nitrogen inozotonhodzwa pazasi peinofashaira kuti inyungudise kuita mvura nitrogen, inova ndiyo musimboti wekuumbwa kwenitrogen yemvura.

Nzira yekugadzira nitrogen yemvura

Muitiro wokugadzira mvura yenitrogen unobatanidza matanho makuru akati wandei: Kutanga, mhepo inotsikirirwa uye inocheneswa kubvisa tsvina yakadai semvura necarbon dioxide; zvino, mhepo isati yatonhodzwa, kazhinji kusvika kumativi -100 ℃ kunatsiridza kupatsanurwa kwakanaka; inotevera, yakadzika kutonhora kuparadzaniswa kunoitwa, zvishoma nezvishoma kutonhora gasi kune liquefaction tembiricha yenitrogen kuwana mvura yenitrogen gasi. Mukuita uku, zvinochinjisa kupisa uye shongwe dzezvikamu zvinotora basa rakakosha mukuona kuparadzaniswa kunoshanda kwezvikamu zvakasiyana patembiricha yakakodzera. Chekupedzisira, iyo nitrogen gasi inochengetwa mumidziyo yakanyatsogadzirirwa kuti ichengetedze tembiricha yakaderera uye kudzivirira kurasikirwa kwemhepo.

Zvinetso zvehunyanzvi mukuumbwa kwenitrogen yemvura

Kuumbwa kwenitrogen yemvura kunoda kukunda matambudziko akati wandei. Yekutanga kuchengetedzwa kwenzvimbo yakaderera-yekushisa, sezvo nzvimbo yekubikira yenitrogen yemvura yakadzikira zvakanyanya. Munguva yekugadzira liquefaction, zvinodikanwa kuchengetedza tembiricha iri pazasi -195.8 ℃, iyo inoda yakakwirira-inoshanda mafiriji michina uye zvekudzivirira. Kechipiri, panguva yekutonhora kwakadzika, kuwedzeredza kweokisijeni kunofanirwa kudzivirirwa nekuti mvura okisijeni ine yakasimba oxidizing zvimiro uye inoisa njodzi dzinogona kuitika. Nokudaro, panguva yekugadzira, nzira yekuparadzanisa nitrogen-oxygen inofanira kunyatsodzorwa, uye zvinhu zvakakodzera zvinofanira kushandiswa kuchengetedza kuchengetedzwa uye kugadzikana kwegadziriro. Pamusoro pezvo, kutakurwa uye kuchengetwa kwenitrogen yemvura kunoda zvakagadzirirwa Dewar flasks kudzivirira kukwira kwekushisa uye kurasikirwa kwe nitrogen vaporization.

Kushandiswa kwemvura yenitrogen

Iyo yakaderera-tembiricha zvimiro zve nitrogen yemvura inoita kuti ishande zvakanyanya munzvimbo dzakasiyana siyana. Mumushonga, nitrogen yemvura inoshandiswa mukucryosurgery uye kuchengetedza matishu, senge kuomesa ganda maronda uye kuchengetedza biological samples. Muindasitiri yechikafu, nitrogen yemvura inoshandiswa kukurumidza kuomesa chikafu, sezvo iyo yakanyanya-yakaderera tembiricha nharaunda inogona kukurumidza kuomesa chikafu, ichideredza kukuvadzwa kwesero chimiro uye nekudaro kuchengetedza kuravira kwepakutanga uye hutano hwechikafu. Mundima yekutsvagisa, mvura nitrogen inoshandiswa zvakanyanya mukutsvagisa superconductivity, yakaderera-tembiricha fizikisi kuyedza, nezvimwewo, ichipa yakanyanya kuderera-tembiricha yekuyedza nharaunda. Pamusoro pezvo, mukugadzira maindasitiri, nitrogen yemvura inoshandiswa mukugadzira simbi, kupisa kupisa, uye seinert gasi kudzivirira mamwe maitiro emakemikari kuti asaitike. Mhedziso

Kuumbwa kwemvura nitrogen maitiro akaomarara emuviri, anonyanya kuwanikwa kuburikidza nemhepo inotonhora yekuparadzanisa nzira uye liquefaction matekinoroji. Iyo yakaderera-tembiricha midziyo yenitrogen yemvura inoita kuti iite basa rakakosha munzvimbo dzakasiyana siyana senge indasitiri, mushonga, uye tsvagiridzo. Kubva pakudhirowa kwenitrogen gasi kusvika kumvura inotonhora yakadzika uye pakupedzisira kusvika pakushandiswa kwayo, nhanho imwe neimwe inoratidza simba remhando yepamusoro yefiriji uye yekuparadzanisa matekinoroji. Mukuita basa, matekinoroji anofanirwawo kuramba achikwenenzvera nzira yekugadzira kuderedza kushandiswa kwesimba uye kugadzirisa kushanda kwemvura nitrogen kugadzirwa.

Isu tiri mugadziri uye mutengesi wemhepo yekuparadzanisa unit. Kana uchida kuziva zvakawanda nezvedu:
