Mfundo zazikulu zogwiritsira ntchito majenereta a nayitrogeni

Majenereta a nayitrogeniamagwiritsa ntchito mpweya ngati zopangira ndipo sefa ya carbon molecular ngati absorbent. Amagwiritsa ntchito mfundo ya pressure swing adsorption ndipo amagwiritsa ntchito sefa ya carbon molecular kuti atenge mpweya ndi nayitrogeni mosankha kuti alekanitse nayitrogeni ndi mpweya. Poyerekeza ndi njira zachikhalidwe. Kupanga kwa Nayitrogeni Njira zake, zili ndi ubwino woyenda mosavuta, mphamvu zambiri zodzipangira zokha, kupanga mpweya mwachangu (mphindi 16-30), kugwiritsa ntchito mphamvu zochepa, kuyera kwa chinthu kumatha kusinthidwa mosiyanasiyana malinga ndi zosowa za ogwiritsa ntchito, kugwiritsa ntchito bwino ndi kukonza, mtengo wotsika wogwirira ntchito, komanso kusinthasintha kwamphamvu kwa chipangizocho. Chifukwa chake, chimakhala chopikisana kwambiri pazida zosakwana 1000Nm3/h ndipo chikudziwika kwambiri pakati pa ogwiritsa ntchito nayitrogeni ang'onoang'ono ndi apakatikati. Chida ichi chakhala chida chabwino kwambiri kwa ogwiritsa ntchito nayitrogeni ang'onoang'ono ndi apakatikati.

The Jenereta ya Nayitrogeni Amasonkhanitsa mpweya wakunja kulowa mu thanki yosungiramo mpweya kudzera mu compressor ya mpweya, kenako amalowetsa mpweya mu thanki yolekanitsa ma electrolytic kuti alekanitse nayitrogeni ndi mpweya mu selo ya electrolytic. Mpweya umatulutsidwa mumlengalenga, ndipo nayitrogeni imatuluka pambuyo poyeretsa ndi kuumitsa. Nayitrogeni imatuluka yokha ndi kuthamanga kwa dongosolo. Chidacho chingagwiritsidwe ntchito nthawi ndi nthawi kapena mosalekeza, ndipo kuyera kwa mpweya wopangidwa sikuwola. Chokhala ndi zida zotetezera zamitundu yambiri, ndi chotetezeka, chodalirika komanso chokhazikika. Chidachi chimapangidwa makamaka ndi njira ya electrolysis, njira yowongolera kuthamanga ndi njira yoyeretsera. Electrolysis ya haidrojeni imagwiritsa ntchito ukadaulo wolekanitsa nembanemba, ndipo kuthamanga kumayendetsedwa ndi chipangizo cha infrared photoelectric. Kutuluka kwa nayitrogeni kumatha kusinthidwa kokha ngati pakufunika kuti kuthamanga kukhale kokhazikika.

Malangizo Ogwiritsira Ntchito Ma Jenereta a Nayitrogeni:

Fyuluta yolowera mpweya ya jenereta ya nayitrogeni iyenera kutsukidwa nthawi zonse. Kuzungulira kwake kumadalira momwe fumbi lilili mkati. Kuyeretsa kwa ultrasound kumatha kusunga cholowera mpweya kukhala chopanda chopinga. Kupanda kutero, n'kosavuta kuwonjezera ntchito ndikutentha compressor. Kutentha kwambiri kukakwera, chitetezo cha kutentha kwambiri chidzachitika, zomwe zimapangitsa kuti chizimitsidwe.

Popeza compressor ya jenereta ya nayitrogeni ndi katundu woyambitsa, mphamvu yamagetsi yomwe imabwera nthawi yomweyo ikayamba kuyatsa ndi kuzimitsa imakhala yokwera kangapo kuposa yomwe imachitika nthawi zonse, ndipo ndi yosavuta kuyiphatikiza, kotero fuse ya 6A iyenera kusankhidwa.

Popeza compressor yokhala ndi chida ichi imagwira ntchito motseguka, mafuta opaka mafuta adzatulutsidwa mu makinawo ndi madzi, zomwe zimapangitsa kuti agwiritsidwe ntchito. Chifukwa chake, patatha chaka chimodzi chogwiritsidwa ntchito, compressor iyenera kupakidwa mafuta bwino, ndipo doko lodzaza mafuta likhoza kukhala pafupi ndi malo otulutsira compressor kapena kuchokera ku malo olowera mpweya. Ndikofunikira kuwonjezera magalamu 200 a mafuta oziziritsira a Nambala 18.

Pofuna kupewa chinyezi chochuluka mu makina ndikusokoneza kuyera kwa mpweya, muyenera kukanikiza chosinthira madzi kwa masekondi angapo musanazimitse nthawi iliyonse. Chitoliro chotulutsira madzi chikhoza kulumikizidwa ku botolo la pulasitiki kuti madzi asalowe, ndipo sichiyenera kukhala chochepera kamodzi patsiku.

Chubu chowumitsira cha jenereta ya nayitrogeni chiyenera kusinthidwa nthawi zonse. Pamene 50% ya silika gel yosintha mtundu mu chubu chowumitsira ikusintha mtundu, phukusi lamkati liyenera kusinthidwa. Njira yosinthira: Zimitsani magetsi ndikutulutsa mpweya wa dongosolo. Tsegulani chubu choyeretsera molunjika komwe kwasonyezedwa ndi muvi, kenako tsegulani chivundikiro cha chubu choyeretsera ndikuyikanso desiccant ya silica gel.

Mukasintha desiccant, samalani kuyika thonje lonse loyamwa mu chitoliro kuti muwonetsetse kuti silikhudza mbali yotseka, kuti muwonetsetse kuti ikhoza kutsekedwa chivundikirocho chitakhazikika.

Jenereta ya nayitrogeni siigwiritsa ntchito KOH panthawi yogwira ntchito, koma tikulimbikitsidwa kusintha electrolyte miyezi isanu ndi umodzi iliyonse. Mukasintha electrolyte, choyamba tulutsani yankho la alkali mu jenereta ya nayitrogeni, onjezerani madzi osungunuka, yambani chidacho, lolani dongosololo liyeretse dongosolo la electrolysis kwa mphindi pafupifupi 6-10, tulutsani madzi osungunuka ndikuwonjezera ku yankho latsopano la electrolytic alkali lokonzedwa. Kuti mugwiritse ntchito bwino njira yoyambira-kusiya kugwira ntchito, mutagwiritsa ntchito jenereta kachiwiri kapena kusintha desiccant, ikani valavu yotulutsa nayitrogeni mu mkhalidwe wa utsi kwa maola awiri, ndikutulutsa chogwirira mpweya mu chubu chowumitsa utasinthidwa kwathunthu.

Nthawi iliyonse mukatseka magetsi a injini yopangira nayitrogeni, chonde tsegulani valavu yotulutsira madzi ya thanki ya gasi kumbuyo kwa jenereta kaye, tulutsani mpweya mu thanki ya gasi, ndikuchepetsa mpweya ndi nayitrogeni kufika pa 0. Kenako tsekani valavu yotulutsira madzi ya thanki ya gasi, kanikizani chogwirira cha valavu yotulutsira madzi ya nayitrogeni mkati, ndipo njira yozimitsa madzi imatsirizika. Mukatseka motsatira njira iyi, nthawi ina mukayamba makina, nthawi yotulutsira madzi imatha kuchepetsedwa kufika pa mphindi 30, ndipo mutha kugwiritsa ntchito nayitrogeni.
