Gwaro Rakakwana reKushanda Kwemutemo wePSA Nitrogen Generators

Chinopa nitrogen chePSA chinowanzo gadzirisa kugoverwa kwenitrogen nguva dzose pasina chikonzero chekutenga masirinda nguva nenguva. Chinoparadzanisa nitrogen neokisijeni panzvimbo yacho, chichishandisa mhepo yakajairika, kuti chigutse zvinodiwa nemabhizinesi kuti pave negesi yakachengeteka kana zvichidikanwa. Izvi zvinowanzo shandiswa mumafekitori ekurongedza chikafu, mafekitori ekucheka nelaser, uye kunyange mafekitori emagetsi. Makambani anogona kusarudza kugadzira nitrogen kana ichidiwa uye kwete kumirira kutumirwa kwayo. Zviri nyore asi pfungwa dziri shure kwayo dzakangwara uye zvinogona kubatsira kuiongorora nhanho nhanho.

Pfungwa Yekutanga Yekuparadzaniswa Kwemhepo Yekugadzira Nitrogen

Pfungwa huru iri mujenareta yePSA nitrogen ndeyekukwanisa kuparadzanisa nitrogen (N2) kubva kune mamwe magasi ari mumhepo, kunyanya okisijeni. Inotanga nemhepo yakajairika kubva mumhepo. Mhepo inomanikidzwa, kana kuiswa munzvimbo diki uko magasi anodzora zviri nyore uye anogona kutamiswa musystem. Mhepo inomanikidzwa uye inopfuura nemusefa yekabhoni molecular yakasiyana kuti idzvanyirire. Maburi echinhu ichi madiki kwazvo uye anosarudza zvakanyanya. Mamorekuru eokisijeni madiki zvishoma pane mamorekuru eN₂ uye anofamba nenzira yakasiyana zvishoma, saka anogona kubatwa zviri nyore musefa. Zvisinei, mamorekuru enitrogen anopfuura nepakati uye anofamba. Kazhinji matangi maviri aya achange achishanda. Rimwe tangi richacheneswa uye richagadziriswazve uye tangi yeokisijeni richaunganidzwa. Chikamu che "pressure swing" chemaitiro acho ndechekuchinjana pakati pezviviri. Rutivi rumwe rwuri pasi pekumanikidzwa kwakanyanya kuparadzanisa magasi uye ipapo kumanikidzwa kunoderedzwa, kuitira kuti okisijeni ibviswe mumusungo. Maitiro acho anodzokororwa. Nekuchinja uku, nitrogen inoramba ichiyerera nguva dzose. Ichi ndicho chikonzero nei maindasitiri anogona kuve nechokwadi chekuti ichashandiswa nguva dzose. Nitrogen inoshandiswa mumutsara wekurongedza chikafu kubvisa okisijeni mukati memapakeji akavharwa kuti iwedzere hupenyu hwesherufu hwezvikafu zvekudya nezvimwe zvigadzirwa zvekudya. Pamaworkshop ekucheka nelaser, nitrogen inoshandiswa kudzivirira kubva kutsvuka kana oxidizing simbi kuti zvidimbu zvive zvakachena. Chakavanzika chekurarama ndechekuti hapana maitiro akaomarara anobatanidzwa uye kuti hapana makemikari anoshandiswa. Inoda kushandiswa kwemhepo chete, kuchinja kwekumanikidza uye zvinhu zvinonyungudutsa. Sisitimu yacho yakagadzirirwa uye mashandiro ayo anochengetwa sezvinodiwa nekutarisira kufamba kwemhepo. Nemashoko akareruka, PSA nitrogen jenareta ifirita yakangwara inokwanisa "kudzivisa" okisijeni uye kubvumira nitrogen kupfuura nepakati.

Maitiro eCarbon Molecular Sies Anoparadzanisa Oxygen neNitrogen

MuPSA nitrogen system, "basa" iri kuitwa muchinhu chinozivikanwa secarbon molecular sieve, kana kuti CMS chete. Inoita semagranule madiki matema, asi ine maburi madiki akawanda mukati megasi rega rega kuti itonge kufamba kwemagasi. Mhepo ine zvinhu zvenitrogen neokisijeni zvine hunhu hwakasiyana zvishoma kana zvakamanikidzwa munzvimbo dzakamanikana. Mamorekuru eokisijeni anoshanda zvishoma uye anofamba nenzira inobatsira kuti atore mumaburi madiki eCMS. Mamorekuru eokisijeni "anotsvedza", zvakadaro, uye anogona kupfuura nepakati zviri nyore. Mubhedha weCMS une mweya wakamanikidzwa, nokudaro uchifambisa okisijeni nenitrogen mumubhedha zvakare. Kana okisijeni isingabvumirwe kupfuura nemaburi, icharamba iri mukati mechimiro. Izvi zvinonzi adsorption kana mamorekuru egasi akanamatira pamusoro pechinhu chacho. Gasi rechigadzirwa rine nitrogen, iyo inoramba ichiyerera ichipinda nekubuda musystem. Mufananidzo wakanaka wekufunga nezvawo i "panzira" ine vanhu vazhinji mairi nesuo diki. Okisijeni yakafanana nevanhu vane mabhegi makuru pamberi pavo akanamirwa pamusuwo; Nitrogen yakafanana nevanhu vane mabhegi madiki pamberi pavo uye inokwana zvakanaka. Sisitimu haingovimbi nemubhedha mumwe chete wekusefa. Mubhedha mumwe chete unoshandiswa kubata okisijeni uye mumwe unoburitswa mhepo kuti ubvise okisijeni yakabatwa woibvisa. Ndiyo danho rekugadzirisazve rinokosha nekuti rinobvumira sefa kuti ishande zvakare. Mushure meizvozvo inochinjana pakati pemibhedha miviri. Uku ndiko kutenderera kunoramba kuripo kwakakosha kuchengetedza kugadzirwa kweN kwakasimba. Izvi zvinogona kuitika munzvimbo yekucheka nelaser uko kuyerera kwenitrogen kwakachena kunodiwa kudzivirira simbi kubva mukuoxidation iri kushandiswa. CMS inobvisa okisijeni isati yasvika kumidziyo, izvo zvinobatsira kuchengetedza mipendero yakachena yekucheka. CMS inoshanda zvakanyanya kwete chete kune zviri mukati, asi nekuti inoshandawo pasi pekumanikidzwa. Inova rudzi rwefirita inozvigadzirisa nguva dzose uye inogadzira nitrogen pasina kukanganiswa.

Maitiro Ekushanda Akakwana eDual-Tower Pressure Swing Adsorption

Sisitimu yekudzvinyirirwa kwesimbi inotenderera ine pressure swing dual tower yakagadzirirwa kuchengetedza kuyerera kwenitrogen kunoenderera mberi. Ine shongwe mbiri dzine huwandu hwakafanana hwecarbon molecular sefa, iyo inoshandiswa zvakasiyana kuita maitiro ekuparadzanisa mhepo. Kutenderera kunotanga kana mweya wakamanikidzwa wapinda mushongwe yekutanga. Kana kumanikidzwa kwakakwira, mukati memamorekuru eokisijeni anonamatira kune zvinhu zviri musefa. Nitrogen haibatike nyore nyore uye inopfuura nepashongwe yobuda segasi rechigadzirwa. Mabasa acho anobva achinjana mushure menguva pfupi. Shongwe yekutanga inotanga kuburitsa kumanikidzwa uye inotanga kugadzikiswa uye shongwe yechipiri inotanga kugadzira nitrogen. Kuchinja uku kunodzorwa kuti kuitike nerhythm yakadzorwa, kazhinji mumasekonzi, uye nekudaro kubuda kunoramba kwakadzikama. Izvi zvinogona kuratidzwa sevashandi vaviri vane purogiramu yekuchinja. Mumwe ari mukugadzirwa uye mumwe ari kuzorora, achigadzirira kutenderera kunotevera. Vanochinjana, saka hapana kumira mukugadzirwa.

Nhanganyaya kuMabasa eChikamu chimwe nechimwe muPSA System

Sisitimu yePSA nitrogen yakafanana necheni, ine chisungo chimwe nechimwe chine basa rayo. Kukundikana kwechikamu chimwe chete kuita basa rayo zvinoreva kuti maitiro ese haana kugadzikana. Kuziva zvikamu izvi kunoita kuti unzwisise zviri nyore kugadzirwa kwenitrogen kana zvichidikanwa. Kazhinji, zvinotanga nekusashanda zvakanaka kwecompressor yemhepo. Iyi unit inokwevera mhepo yakajairika uye inoidzvanya kusvika pakumanikidzwa kwakakodzera. Kana danho iri rikasatorwa, mhepo inenge isina simba rekushandiswa mukuparadzanisa. Mhepo yakamanikidzwa ichiri kupisa uye inogona kunge iri mvura kana guruva. ​​Apa ndipo panopinda chikamu chekurapa mhepo. Mafirita nemadryer anochenesa mhepo isati yaiswa muhurongwa hukuru. Maitiro aya anobatsira kuchengetedza carbon molecular sieve uye kuchengetedza kugadzikana kwekushanda nekufamba kwenguva nekuda kwekubviswa kweguruva neutsi hwemvura. Inotevera itangi reAir Receiver. Izvi zvakafanana nebuffer. Inobvisa chero nyonganyonga mukuyerera kwemhepo muyuniti yePSA, ichivimbisa kuyerera kwakasimba kwemhepo yakamanikidzwa. Izvi zvinobatsira kuchengetedza kumanikidzwa panguva yekushanda.Tevere, chikamu chikuru chehurongwa inhare mbiri dzinonyungudutsa dzakazadzwa nemasefa ecarbon molecular.Nhare mbiri dzinonyungudutsa dzine masefa ecarbon molecular dzinobva dzave moyo wehurongwa.Nhare idzi dzinochinjana mukuparadzaniswa kweokisijeni nenitrogen.Nhare imwe iri kugadzira Nitrogen uye imwe iri kucheneswa uye kugadziriswazve. Kuchinja uku kunoita kuti kugadzirwa kusavhiringidzwe.

Zvinhu Zvikuru Zvinokanganisa Kuchena kweNitrogen uye Mwero weKuyerera kweNitrogen

Huwandu hwenitrogen yakachena uye mwero wayo wekubuda muPSA system hauna kugadzikwa. Zvinosiyana zvichienderana nenzvimbo uye kushandiswa kwesystem. Kune zvinhu zvishoma zvakakosha zvinoita basa guru mukuchena kwegasi reN2 uye kuti gasi rakawanda sei rinogona kugadzirwa muhuwandu hwakati. Chimwe chezvinhu zvakakosha kumanikidzwa kwemhepo. PSA nitrogen jenareta midziyo Sisitimu inofanira kuva nehuwandu hwakakodzera hwekumanikidzwa kuti ive nechokwadi chekuti gasi reokisijeni rinopinda musefa yecarbon molecular. Kumanikidzwa kusina kukwana hakubatsiri pakupatsanurwa kweokisijeni uye kunoderedzawo kuchena kwenitrogen. Kana yakakwira zvakanyanya, pane mukana wekuti sisitimu icharasikirwa nesimba pasina kuburitsa zvakawanda. Kugadziriswa kunowanzoitwa ndeyekuchinja kumanikidzwa kuti uwane chiyero chakakodzera. Chimwe ndechekuti mhepo ichafamba nekukurumidza sei. Gasi rakawanda rinounzwa panguva imwe chete, izvo zvisina kukwana kuti sefa ishande nemazvo. Izvi zvinogona kukonzera kuti mhando yenitrogen iderere. Asi mumamiriro emhepo isina kuyerera zvakanaka, kushomeka kwezvigadzirwa uye kusashanda zvakanaka kunogona kuitika. Chero kuchena uye kuenzana kwekumhanya.
