VPSA Oxygen jenareta

Tsananguro Pfupi:

Psa okisijeni yekugadzira michina, pasi pemamiriro etembiricha yekamuri uye kumanikidza kwemhepo, INOSHANDISA yakasarudzika VPSA mamoresi nesefa kuti isarudze inotora nitrogen, kabhoni dhayokisaidhi nemvura nezvimwe zvakasviba mumhepo, kuti uwane oxygen nekuchena kwakanyanya (93 ± 2% ).

Chinyakare kugadzirwa kweoksijeni kazhinji inotora nzira yekuparadzanisa cryogenic, iyo inogona kuburitsa okisijeni nekuchena kwakanyanya. Nekudaro, iyo michina ine yakakwira mari, uye iyo michina inoshanda pasi penzvimbo yekumanikidza kwakanyanya uye Ultra-yakaderera tembiricha. Kuvhiya kwacho kwakaoma, chiyero chekuchengetedza chakakwirira, uye simba rekushandisa rakakwira, uye rinowanzo fanira kupfuura nemumaawa akawanda kuti riwanzoburitsa gasi mushure mekutanga.

Sezvo psa okisijeni yekugadzira michina yakapinda muindasitiri, iyo tekinoroji yakawedzera nekukurumidza, nekuti mutengo wayo unoshanda kupfuura mune yakaderera goho renji uye izvo zvinodiwa zvechena hazvina kunyanya kukwirira mumamiriro acho zvine kukwikwidza kwakasimba, saka inoshandiswa zvakanyanya mukunyungudika, blast furnace oxygen enrichment, pulp blekning, girazi choto, kurapwa kwemvura yakasviba uye mimwe minda.

Kutsvagurudzwa mudzimba pahunyanzvi uhu kwakatanga kare, asi munguva yakareba kukura kwacho kunononoka.

Kubva kuma1990, zvakanakira psa okisijeni yekugadzira michina yakave ichizivikanwa zvishoma nezvishoma nevanhu vechiChinese, uye mumakore achangopfuura, maitiro akasiyana siyana emidziyo akaiswa mukugadzirwa.

Iyo psa VPSA okisijeni yekugadzira michina yeHangzhou Boxiang Gas Equipment Co., Ltd. ine chinzvimbo chinotungamira mumunda wefetireza indasitiri, uye maitiro ayo anoshamisa kwazvo.

Imwe yematanho makuru ekuvandudza epsa ndeye kudzikisa huwandu hweanoshambadzira uye nekuvandudza kugona kwemidziyo. Nekudaro, iko kuvandudzwa kwema molecular sieve ekugadzira oksijeni kunogara kuchiitwa munzira yekukwira senitrogen adsorption mwero, nekuti kushambadzira mashandiro emaseru molese ndiyo hwaro hwePSA.

Iyo sieve yemasero ine mhando yakanaka inofanirwa kuve neakakwira nitrogen uye okisijeni yekuparadzanisa coefficient, saturation adsorption kugona uye yakasimba simba.

Psa imwe huru yekuvandudza nzira ndeyekushandisa ipfupi kutenderera, inoda kwete chete yakavimbiswa mhando yemolecular sieve, panguva imwechete inofanirwa kuve yakavakirwa pane kushambadzira shongwe yemukati dhizaini yekugadzirisa, kuitira kudzivirira izvo zvinogona kukonzera kuti chigadzirwa chive chakaipa uye iyo kutadza kwekusaenzana-yunifomu kugoverwa kwemweya wegesi mus adsorption tower, uye zvakare kuisa kumberi kwakakwirira zvinodikanwa kune butterfly vharuvhu switch.

Mune mazhinji maPSA okisijeni maitiro ekugadzira, PSA, VSA uye VPSA inogona kuve yakarongedzwa mumhando nhatu.

PSA ndiyo yakanyanya hombe kumanikidza kushambadzira mudenga dhizaini maitiro. Iine zvakanakira zvakapusa unit uye zvakaderera zvinodiwa kune mamorekuru sieve, uye zvakaipira zvekushandisa kwakanyanya kwesimba, iyo inofanirwa kushandiswa mune zvidiki zvishandiso.

VSA.

VPSA ndiyo nzira yekutsvaira dhizaini kuburikidza nemhepo yekumanikidza. Iine zvakanakira yakaderera simba yekushandisa uye yakanyanya kushanda kweanosiya sieve. Iko kudyara kwese kwemidziyo kwakadzikira zvakanyanya kupfuura kuya kweiyo VSA maitiro, uye zvinokanganisika zviri zvidiki zvakanyanya zvinodiwa kune mamorekuru sieve uye vharafu.

Hangzhou Boxiang gasi inotora maitiro eVPSA, uye inoita shanduko huru pane yechinyakare maitiro uye maitiro, ayo asingori chete ekudzora kushandiswa kwesimba kusvika padiki (zvinoreva kushandiswa kweiyo imwechete brand molecular sieve), asi zvakare inozadzisa chinangwa chekurerutsa uye miniaturization yemidziyo, inoderedza kudyara, uye ine yakakwira kuita / mutengo wero.

Iyo yese psa okisijeni yekugadzira sisitimu inonyanya kuumbwa neye blower, pombi yekutsiva, switching vharuvhu, absorber uye oksijeni kumanikidza booster unit ye oxygen muyero tangi.

Mushure mekuburitswa kweguruva nezvimedu zvekutsveta, mweya mbishi unomanikidzwa kuenda ku0,3 ~ 0.4 Barg neMidzi blower uye inopinda mune imwe yeanoshambadza.

Iyo adsorbent yakazadzwa mu adsorbent, umo mvura, kabhoni dhayokisaidhi, uye hushoma hwezvimwe zvikamu zvegesi zvinoshambadzwa panopinda iyo adsorbent neakagadzwa alumina pazasi, uyezve nitrogen inoshambadzirwa neyakagadziriswa alumina uye zeolite pamusoro peiyo 13X molecular sieve.

Oxygen (kusanganisira argon) ndiyo isiri-adsorbed chinhu uye inobviswa kubva kumusoro kwekushambadzira kune iyo okisijeni tank tangi sechigadzirwa.

Kana adsorbent yashambadzwa kune imwe nhanho, iyo adsorbent inosvika pakuzadza nyika. Panguva ino, pombi yekutsvaira inoshandiswa kushambidza iyo adsorbent kuburikidza neiyo switching vharuvhu (inopesana nekwesheni yekushambadzira), uye iyo yekutsiva degree iri 0.45 ~ 0.5BARg.

Iyo inonwiwa mvura, kabhoni dhayokisaidhi, senitrogen uye diki diki yezvimwe zvikamu zvegasi zvinowirwa mumhepo uye iyo adsorbent inogadziriswazve.
Imwe neimwe adsorber inochinja pakati pematanho anotevera:
- adsorption
- kubviswa
- kutsika
Aya matanho ari pamusoro matatu ekutanga matanho anodzorwa nePLC uye nekuchinja vharuvhu system.

Kushanda Musimboti

Aya matanho ari pamusoro matatu ekutanga matanho anodzorwa nePLC uye nekuchinja vharuvhu system.
1. Musimboti wekuparadzaniswa kwemhepo psa kugadzira oxygen
Izvo zvakakosha mumhepo ndeye nitrogen uye oxygen. Naizvozvo, adsorbents ane akasiyana adsorption sarudzo ye nitrogen uye okisijeni inogona kusarudzwa uye yakakodzera tekinoroji maitiro anogona kugadzirirwa kupatsanura nitrogen uye oksijeni kuburitsa oxygen.
Ose maviri maitrogen uye oksijeni ane nguva dzeana quadrupole, asi nitrogen's quadrupole nguva (0.31 A) yakakura kwazvo kupfuura oxygen's (0.10 A), saka nitrogen ine Simba rakasimba rekushambadzira pane zeolite molecular sieve pane oxygen (nitrogen ine Simba rakasimba rine ion pamusoro. ye zeolite).
Naizvozvo, kana mweya uchipfuura nemubhedha we adsorption une zeolite adsorbent iri pasi pekumanikidzwa, nitrogen inoshambadzwa neiyoolite, uye okisijeni haina kunyura, saka inowedzeredzwa muchikamu chegesi uye inoyerera ichibva pamubhedha we adsorption, ichigadzira oxygen uye nitrogen yakaparadzaniswa ne wana oxygen.
Kana iyo mamorekuru sieve adsorbs nitrogen kusvika padyo nekuzadza, mweya unomiswa uye kumanikidzwa kwemubhedha we adsorption kwadzikiswa, iyo nitrogen inoshambidzwa neesefa yemolekyuli inogona kubviswa kunze, uye nesefa yemolekyuli inogona kugadziriswazve uye kushandiswazve.
Oxygen inogona kugadzirwa ichienderera nekuchinja pakati pemabhedha maviri kana anopfuura ekushambadzira.
Iyo yekubikira poindi yeArgon neoksijeni iri padhuze nepadhuze, saka zvinonetsa kupatsanura, uye ivo vanogona kuzadziswa pamwechete muchikamu chegesi.
Naizvozvo, iyo psa okisijeni yekugadzira chishandiso kazhinji inogona kungowana iko kusungwa kwe80% ~ 93% okisijeni, zvichienzaniswa neyakaunganidzwa ye99.5% kana yakawanda okisijeni mune iyo cryogenic yekuparadzanisa mweya mudziyo, inozivikanwawo seoksijeni-yakapfuma.
Zvinoenderana nenzira dzakasiyana dzekusiya, psa okisijeni kugadzirwa kunogona kuganhurwa

Maitiro maviri

1. PSA maitiro: kumanikidza adsorption (0.2-0.6mpa), mudenga desorption.
PSA yekushandisa michina yakapusa, diki yekudyara, asi yakaderera okisijeni goho, yakanyanya simba yekushandisa, inokodzera zvidiki-zvidiki kugadzirwa kweoksijeni (kazhinji <200m3 / h) nguva.

2. Maitiro eVPSA: kushambadzira pasi pechisimba kumanikidza kana kukwira zvishoma pane zvakajairika kumanikidza (0 ~ 50KPa), yekutsiva yekubvisa (-50 ~ -80kpa) desorption.
Inofananidzwa nePSA maitiro, VPSA yekushandisa michina yakaoma, yakakwira mari, asi kushanda kwakanyanya, kushomeka kwesimba kwesimba, inokodzera pamwero wakakura wekugadzira okisijeni.

Zvekuparadzanisa chaiko, zvimwe zvekuteedzera mumhepo zvinofanirwa kutariswa.
Iyo adsorption inokwana kabhoni dhayokisaidhi uye pane zvakajairika adsorbents inowanzo kuve yakakura kwazvo kupfuura iyo yenitrogen uye oxygen. Iwo ma adsorbents anogona kuzadzwa mumubhedha we adsorption neakakodzera adsorbents (kana kushandiswa kweoksijeni kugadzira adsorbents ivo pachavo) kuti vagone kunyudzwa uye kubviswa.

General technical Ongororo yeVPSA okisijeni yekugadzira michina:
Ø kutora tekinoroji yepamberi, hunyanzvi hwekukura, yakaderera simba rekushandisa uye mashandiro emari yekushongedza maviri psa okisijeni yekugadzira maitiro;
Ø kufunga uye, kuburikidza nekuongororwa kwechimiro seti yakazara yemidziyo, mhando yepamusoro kuve nechokwadi chekuvimbika uye kugadzikana kweiyo system mashandiro;
Ø midziyo, inyore kuvhiya kuchinjika;
Ø yakanyanya otomatiki maitiro ekudzora, iyo yepakati manejimendi yepakati yekudzora imba;
Yakanaka-system chengetedzo, michina yekutarisa, matanho ekudzivirira kukanganisa kugadzirisa;
Ø isina kusvibiswa kwezvakatipoteredza;
Ø okisijeni michina yekuita yekupedzisira kuburitswa yePeople's Republic of China yenyika zviyero uye mushumiro muyero wemakanika indasitiri.
