Maitiro ekusarudza jenareta yenitrogen yakakodzera

Usati wasarudza marongero chaiwo emuenzaniso (kureva Kugadzirwa kweNitrogen paawa imwe neimwe, kuchena kwenitrogen, kumanikidzwa kwekubuda, dova point), tinofanira kutarisa pakuongorora kwakazara kwekushanda uye hunhu hwejenareta yenitrogen, uye ita sarudzo chaiyo zvichienderana nemamiriro edu ezvinhu aripo.

Zvinodiwa zvenitrogen mumaindasitiri akasiyana-siyana

A, Maindasitiri ekugadzira simbi nesimbi

Mamwe emaindasitiri aya anoda nitrogen ine hutsanana hunopfuura 99.5%, nepo mamwe achida nitrogen yemhando yepamusoro ine hutsanana hunopfuura 99.9995% uye dova rakaderera pane -65°C. Izvi zvinofanirwa kutsanangurwa zvichienderana nemamiriro ekugadzirwa kwemutengi.

B, Maindasitiri emakemikari nezvinhu zvitsva

Kazhinji, zvinodiwa kuti nitrogen ive yakachena hazvina kunyanya kukwira, uye nitrogen yakawanda inodarika 98% inogona kushandiswa. Zvisinei, zvinodiwa chaizvo zvinoenderana nemaitiro emutengi pachake ekugadzira.

C, Maindasitiri ezvekudya nemishonga

Maindasitiri mazhinji ezvekudya haana zvinodiwa zvakanyanya zvenitrogen, uye 99.5% ~ 99.9% kuchena kunogona kusangana nezvinodiwa. Maindasitiri mashoma ezvekudya anofanira kusarudza 99.99% kuchena nekuda kwezvinodiwa pakugadzira. Indasitiri yemishonga inowanzoda nitrogen kuchena kwe99.99% uye inoda kuti igadziriswe nesimbi isingatsvi.

d Indasitiri yezvemagetsi

Kazhinji, zvinodiwa zvenitrogen zvakakwirira, uye kazhinji nitrogen yakachena ye99.99% kana kupfuura inodiwa.

Kuenzanisa pakati pezvinhu zvakasiyana-siyana Jenareta yeNitrogens

A, Jenareta yenitrogen yekuparadzanisa mhepo inonzi Cryogenic

Kugadzira nitrogen yemhepo inopatsanurwa (cryogenic air separation) inzira yechinyakare yekugadzira nitrogen ine nhoroondo yemakumi emakore akati wandei. Inoshandisa mhepo sechinhu chisina kugadzirwa, inoidzvanya uye inoichenesa, uye yobva yashandisa kuchinjana kwekupisa kuti inyungudise mhepo kuita mhepo ine mvura. Mhepo ine mvura inonyanya kusanganiswa neokisijeni yemvura nenitrogen yemvura. Nzvimbo dzakasiyana dzekufashaira dzeokisijeni yemvura nenitrogen yemvura (pamhepo imwe chete, nzvimbo yekufashaira yeyokutanga i -183℃ uye yekupedzisira i -196℃) dzinoshandiswa kudziparadzanisa kuburikidza nekunyungudutsa mhepo ine mvura kuti iwane nitrogen. Midziyo yekugadzira nitrogen yemhepo inopatsanurwa (cryogenic air separation) yakaoma, inogara munzvimbo yakakura, ine mari yakawanda yezvivakwa, inoda mari yakawanda yekudyara kamwe chete mumidziyo, ine mari yakawanda yekushanda, kugadzirwa kwegasi kunononoka (maawa 12 kusvika 24), ine zvinodiwa zvakanyanya zvekuisa, uye inotenderera kwenguva refu. Tichifunga nezvezvinhu zvemidziyo, kuiswa uye zvivakwa, chiyero chekudyara chemidziyo yePSA ine zvirevo zvakafanana pasi pe3500Nm3/h chakaderera ne20% kusvika 50% pane chemidziyo yekuparadzanisa mhepo inopenya (cryogenic air separation). Midziyo yekugadzira nitrogen inopatsanurwa nemhepo ine cryogenic yakakodzera kugadzirwa kwenitrogen mumaindasitiri makuru, nepo kugadzirwa kwenitrogen yepakati nepakati nediki kusingadhuri.

B, jenareta yenitrogen inokweverwa nePSA inodzvanywa nekudzvanywa

Nzira yekushandisa mhepo sezvinhu zvakabikwa, sefa yekabhoni semusefa, kushandisa musimboti wekudzvanya kwemhepo, uye kushandisa nzira yekusarudza yekunyungudutsa okisijeni nenitrogen nesefa yekabhoni kuti iparadzanise nitrogen neokisijeni inowanzonzi Kugadzirwa kwenitrogen yePSAIyi nzira inyanzvi itsva yekugadzira nitrogen yakatanga nekukurumidza muma1970. Kana ichienzaniswa nenzira dzechinyakare dzekugadzira nitrogen, ine hunhu hwekuyerera kuri nyore kwemaitiro, mwero wepamusoro we otomatiki, kugadzirwa kwegasi nekukurumidza (maminetsi 15-30), kushandiswa kwesimba shoma, kuchena kwechigadzirwa kunogona kugadziriswa mukati mehuwandu hwakakura zvichienderana nezvinodiwa nemushandisi, kushanda nekugadziriswa kuri nyore, mutengo wakaderera wekushanda, kuchinjika kwakasimba kwemidziyo, nezvimwewo. Saka, inokwikwidza zvakanyanya mumidziyo yekugadzira nitrogen iri pasi pe1000Nm3/h, uye iri kugamuchirwa zvakanyanya nevanoshandisa nitrogen vari pakati nepakati nepadiki. Psa Nitrogen kugadzira kwave nzira inoshandiswa nevanoshandisa nitrogen vari pakati nepakati nevashoma.

C, Jenareta yenitrogen yekuparadzanisa membrane

Uchishandisa mhepo sechinhu chisina kugadzirwa, pasi pemamwe mamiriro ekumanikidzwa, okisijeni nenitrogen zvinoparadzaniswa nekushandisa mwero wakasiyana wekupenya kwemagasi ane hunhu hwakasiyana senge okisijeni nenitrogen mumembrane. Kana ichienzaniswa nemimwe michina yekugadzira nitrogen, ine zvakanakira zvechimiro chiri nyore, saizi diki, hapana vharuvhu yekuchinja, kugadzirisa kushoma, kugadzirwa kwegasi nekukurumidza (≤3 maminitsi), uye kuwedzera kugona kuri nyore. Yakakodzera zvakanyanya kune vashandisi venitrogen vepakati nepakati nevechidiki vane nitrogen yakachena ≤98%, uye ine chiyero chakanakisa chebasa-mutengo. Kana nitrogen yakachena iri pamusoro pe98%, mutengo wayo unodarika 15% kupfuura wevanogadzira nitrogen vePSA vane specification dzakafanana.

Zvinhu zvinokanganisa mutengo wevanogadzira nitrogen

1. Mutengo wekutenga kamwe chete wehurongwa hwese. Parizvino, kune mhando dzakawanda mumusika, uye mhando yacho inoenderana nemutengo.

2. Kugadzikana kwekushanda kwemidziyo uye hupenyu hwebasa hunofungidzirwa.

3. Mari yekushandisa nekugadzirisa yegore negore.

4. Mari yemvura nemagetsi pazuva.
