Momwe mungapangire mpweya wautali wa nayitrogeni kuchokera kumlengalenga?
1. Njira yolekanitsa mpweya
Njira yolekanitsa ya Chrogenic yadutsa zaka zoposa 100, ndipo zakhala zikuchitika zosiyanasiyana magetsi apamwamba, mphamvu yamagetsi komanso yotsika mtengo, komanso magetsi ochepa. Ndi chitukuko cha ukadaulo wamakono wa mpweya ndi zida, njira yapamwamba kwambiri, yomwe imakhazikika, yotsika komanso yotsika, komanso sing'anga vasuum idathetsedwa. Njira yotsika kwambiri - njira yotsika yokhala ndi mphamvu zotsika komanso kupanga zotetezeka zakhala chisankho choyambirira cha zida zazikulu komanso zapakatikati. Njira yotsika kwambiri - yogawana mpweya imagawika molingana ndi njira zakunja komanso kapangidwe kake molingana ndi maulalo osiyana siyana ndi zinthu za nitrogen. Njira yotsika kwambiri - yomwe ikuwoneka bwino yakunja imatulutsa mpweya wotsika kapena nayitrogeni, kenako amakakamiza mpweya wamalonda kuti upatse wogwiritsa ntchito kudzera pa compressi yakunja. Kupanikizika kwathunthu kwa otsika-kuponderezedwa kumathandizira mpweya wamadzimadzi kapena madzi a nayitrogen omwe apangidwa ndi dispillation atalandiridwa ndi mankhwalawa omwe amagwiritsidwa ntchito pambuyo pa chipangizo chosinthira. Njira zazikuluzikuluzi zikuwasefa, kuponderezana, kukongoletsa, kuyeretsa, kudzikuza, kudzipatula, komanso kupatsidwa mpweya wakunja kwa mpweya waiwisi.
2. Kukakamiza Kusintha Kwa ADSORORARPES (Njira ya PSA)
Njirayi imakhazikitsidwa chifukwa cha mpweya wothinikizidwa ngati zopangira. Nthawi zambiri, kuwunika kwa maselo kumagwiritsidwa ntchito ngati adsorbent. Pakukakamizidwa kwina, kusiyana mu mayamwidwe oxygen ndi mamolekyu a nitrogen mumlengalenga molekyoni amagwiritsidwa ntchito. Pazosankha zamafuta, kulekanitsa mpweya wabwino ndi nayitrogeni kumachitika; Ndipo molecular speave yotenga wothandizirana ndikuwunikanso pambuyo pochotsa.
Kuphatikiza pa sives, adsorbents amathanso kugwiritsa ntchito alumu ndi silicone.
Pakadali pano, kugwiritsidwa ntchito kodziwika bwino kwa adsorption nayitrogeni kupanga chida kumakhazikika pa mpweya, kaboni kaboni Choyamba, mpweya mlengalenga umakhazikitsidwa ndi mamolekyu a kaboni, omwe amaphatikiza nayitrogeni mu gawo la gasi. Pofuna kupeza nayitrogen mosalekeza, nsanja ziwiri za Adsororption zimafunikira.
Karata yanchito
1. Mankhwala a nayitrogeni ndi okhazikika ndipo samvera zinthu zina. Khalidwe losafunikirali limapangitsa kuti ligwiritsidwe ntchito m'malo ambiri a anaerobic, monga kugwiritsa ntchito nayitrogeni kuti ilowe m'malo mwapadera, yomwe imapanga gawo lodzipatula, lawi, ndi anticorrossion. Livisi ya LPG, mapisi a gasi ndi ma bronchial a bronchial a networks amagwiritsidwa ntchito pakugwiritsa ntchito mafakitale ndi kugwiritsa ntchito zachitukuko [11]. Nitrogen zitha kugwiritsidwanso ntchito pakupanga zakudya zopangidwa ndi mankhwala ophimba, zingwe zikakulu, matebulo, komanso amakanikiza matayala a mphira omwe amatha kukula. Monga mtundu wosungirako, nayitrogeni nthawi zambiri amasinthidwa ndi pansi panthaka kuti achepetse chimbudzi chopangidwa ndi kulumikizana pakati pa chubu ndi stratum madzimadzi.
2. Nayitrogeni wapamwamba amagwiritsidwa ntchito ngati chitsulo chosungunuka kukonza zitsulo kuti ukhalesungunuke kuti ukhale wabwino. Gasi, imalepheretsa kutentha kwambiri makomera amkuwa, amakhala pamwamba pa zamkuwa, ndikuchotsa njira yonyamula. Nitrogeni -Arbor-brogen accoce mpweya (kapangidwe kake ndi: 64.1% n2, 34% CO, 1.2% h2 ndi gasi yoteteza nthawi yamkuwa.
3. Pafupifupi 10% ya nayitrogeni yopangidwa ngati firiji, imaphatikizaponso: Nthawi zambiri zimakhala zofewa kapena ngati zotsekemera, komanso zoyeserera, monga kuteteza magazi kwa magazi poyendera.
4. Nitrogen zitha kugwiritsidwa ntchito pophatikiza nitrive oxide kapena nayitrogeni dioxide kuti apange nitric acid. Njira yopanga iyi ndiyokwera ndipo mtengo wake ndi wotsika. Kuphatikiza apo, nayitrogeni amathanso kugwiritsidwa ntchito popanga ammonia ndi chitsulo nistride.
