| Njodzi dzehutano: | Iyo nitrogen iri mumhepo yakawandisa, izvo zvinoderedza voltage yemhepo inofema, zvichikonzera hypoxia uye kutadza kufema. Kana kuwanda kwe nitrogen inhalation kusati kwanyanya, murwere pakutanga akanzwa chipfuva chakaoma, kupfupika kwekufema, uye kupera simba; ipapo pakava nokushatirwa, kufara kukuru, kumhanya, kudanidzira, kusafara, uye kufamba kusina kugadzikana. Kana pakoma. Inhale high concentration, varwere vanogona kukurumidza coma uye kufa nekuda kwekufema uye kurova kwemoyo. Apo iyo diver inotsiva zvakadzama, anesthesia effect ye nitrogen inogona kuitika; kana ikatamiswa kubva kune yakakwira yekumanikidza nharaunda kuenda kune yakajairwa kudzvanywa nharaunda, iyo nitrogen bubble ichaumba mumuviri, kudzvanya tsinga, tsinga dzeropa, kana kukonzera bheji tsinga yeropa, uye "decompression decompression" inoitika. |
| Kupisa ngozi: | Nitrogen haibatike. |
| Inhale: | Kurumidza kubva panzvimbo yacho kumhepo itsva. Chengetedza nzira yekufema yakavhurika. Kana kufema kwakaoma, ipa oxygen. Kana kurova kwemoyo wekufema kwamira, kurumidza kuita kufema kwechisikigo uye chifuva chinomanikidza kuvhiya kuti uwane kurapwa. |
| Nengozi maitiro: | Kana ikasangana nefivha yakakura, kumanikidzwa kwemukati kwemudziyo kunowedzera, uye iri pangozi yekuputika uye kuputika. |

1. Cryogenic Air Separation Method
Iyo Cryogenic separation method yakapfuura makore anopfuura zana ebudiriro, uye yakasangana nemhando dzakasiyana siyana dzemaitirwo akadai seyakakwira voltage, yakakwira uye yakaderera voltage, yepakati pressure, uye yakazara low low voltage process. Nekuvandudzwa kweyemazuva ano tekinoroji yemhando yemhepo uye michina, maitiro e-high-voltage, yakakwira uye yakaderera kudzvanywa, uye yepakati-voltage vacuum yakabviswa. Iyo yakaderera yakaderera-kudzvanywa maitiro ine yakaderera simba rekushandisa uye yakachengeteka kugadzirwa yave sarudzo yekutanga kune yakakura uye yepakati-saizi yakaderera -temperature vacuum zvishandiso. Iyo yakazara yakaderera-voltage air division process yakakamurwa kuita ekunze compression maitiro uye mukati compression maitiro zvichienderana neakasiyana compression link yeokisijeni uye nitrogen zvigadzirwa. Iyo yakazara yakaderera -kudzvanywa kwekunze kwekumanikidza kunoburitsa yakaderera -kudzvanywa okisijeni kana nitrogen, uyezve inomanikidza chigadzirwa gasi kune inodiwa kudzvanywa kuti ipe mushandisi kuburikidza nekunze compressor. Kudzvinyirirwa kwakazara mu-low-pressure compression process The liquid oxygen kana liquid nitrogen inogadzirwa ne distilled distillation inogamuchirwa nemapombi emvura mubhokisi rinotonhora kuti aputsike mushure mekumanikidzwa kunodiwa nemushandisi, uye mushandisi anopiwa mushure mekupisa zvakare mumudziyo mukuru wekutsinhanisa kupisa. Maitiro makuru ndeekusefa, kudzvanya, kutonhora, kucheneswa, supercharger, kuwedzera, distillation, kupatsanura, kupisa-kusangana, uye kunze kwekupa kwemhepo yakasvibirira yemhepo.
2. pressure swing adsorption nzira (PSA nzira)
Iyi nzira yakavakirwa pamhepo yakamanikidzwa seyakagadzirwa. Kazhinji, kuongorora kwema molecular kunoshandiswa seye adsorbent. Pasi peimwe dzvinyiriro, musiyano mukutorwa kweokisijeni nenitrogen mamorekuru mumhepo mumasefa akasiyana-siyana anoshandiswa. Mukuunganidza gasi, kupatsanurwa kweokisijeni nenitrogen kunoitwa; uye molecular sieve absorbing agent yakaongororwa uye yakadzokororwa mushure mekudzvinyirirwa kubviswa.
Kuwedzera kune masieve mamorekuru, adsorbents anogona zvakare kuisa alumina uye silicone.
Parizvino, iyo inowanzoshandiswa transformer adsorption nitrogen kugadzira mudziyo yakavakirwa pamhepo yakamanikidzwa, kabhoni molecular sieve seye adsorbent, uye inoshandisa misiyano yeadsorption capacity, adsorption rate, adsorption simba reokisijeni uye nitrogen pane kabhoni molecular sieves uye Kushushikana kwakasiyana kune akasiyana adsorption kugona hunhu kuti uwane okisijeni uye nitrogen kupatsanura. Chekutanga pane zvese, okisijeni mumhepo inoiswa pamberi nekabhoni mamorekuru, ayo anopfumisa nitrogen muchikamu chegasi. Kuti uwane nitrogen nguva dzose, maviri adsorption tower inodiwa.
Application
1. Makemikari enitrogen akadzikama uye kazhinji haapindure kune zvimwe zvinhu. Iyi inertial quality inobvumira kuti ishandiswe zvakanyanya munzvimbo dzakawanda dzeanaerobic, dzakadai sekushandisa nitrogen kutsiva mhepo mune imwe mudziyo, iyo inobata basa mukuzviparadzanisa, kupisa kwemoto, kuputika-kupikisa, uye anticorrosion. LPG engineering, magasi mapaipi uye liquefied bronchial network inoiswa pakushandiswa kwemaindasitiri uye kushandiswa kwevanhu [11]. Nitrogen inogonawo kushandiswa pakurongedza zvekudya zvakagayiwa nemishonga sekuvhara magasi, tambo dzekunamisa, tambo dzenhare, uye matai erabha anotsikirirwa anogona kuwedzera. Serudzi rwekuchengetedza, nitrogen inowanzotsiviwa nepasi pevhu kuti inonoke kukora kunokonzerwa nekubatana pakati pechubhu column uye stratum fluid.
2. High-purity nitrogen inoshandiswa musimbi inonyunguduka kukanda nzira yekunatsa simbi inonyunguduka kuvandudza kunaka kwekukanda kusina chinhu. Gasi, inodzivirira zvakanyanya tembiricha oxidation yemhangura, inochengeta pamusoro pezvinhu zvemhangura, uye inobvisa maitiro ekunhonga. Iyo nitrogen-based charcoal furnace gasi (yakaumbwa ndeye: 64.1% N2, 34.7% CO, 1.2% H2 uye zvishoma CO2) segasi rinodzivirira panguva yekunyunguduka kwemhangura, kuitira kuti mhangura inonyunguduka inoshandiswa inoshandiswa unhu hwechigadzirwa.
3. Inenge 10% yenitrogen inogadzirwa sefiriji, inonyanya kusanganisira: kazhinji yakapfava kana yakafanana nerabha -kufanana nekusimbisa, yakaderera -temperature yekugadzirisa rabha, kutonhora kwekugadzirisa uye kuiswa, uye zvipenyu zvehupenyu, zvakadai sekuchengetedza ropa kweropa Kutonhorera mukufambisa.
4. Nitrogen inogona kushandiswa kugadzira nitric oxide kana nitrogen dioxide kugadzira nitric acid. Iyi nzira yekugadzira yakakwirira uye mutengo wakaderera. Mukuwedzera, nitrogen inogonawo kushandiswa kugadzira ammonia uye simbi nitride.
