VPSAO vacuum pressure swing adsorption okisijeni kugadzira michina
Kushanda musimboti
Zvinhu zvikuru zviri mumhepo nitrogen uye okisijeni, uchishandisa ambient tembiricha, nitrogen uye okisijeni mumhepo mu zeolite molecular sieve (ZMS) adsorption kuita kwakasiyana (okisijeni inogona kupfuura uye nitrogen adsorption), gadzira nzira yakakodzera, uye ita nitrogen. uye kupatsanurwa kweokisijeni kuti uwane oxygen.Nitrogen pane zeolite molecular sieve adsorption kugona iri nani pane oxygen (nitrogen ion uye molecular sieve surface force simba rakasimba), apo mhepo yemhepo iri munyika ine zeolite molecular sieve adsorbent adsorption bed, nitrogen by molecular sieve adsorption. , okisijeni shoma kuburikidza neadsorption, concentration uye kuyerera mugasi phase adsorption bed, the oxygen and nitrogen separation for oxygen.Apo molecular sieve adsorption nitrogen to saturated, misa mhepo uye kuderedza kudzvinyirirwa kwemubhedha weadsorption, molecular sieve adsorption nitrogen shanduko yakagadziriswa, molecular sieve regeneration uye inogona kushandiswa zvakare.Kana maviri kana anopfuura adsorption mibhedha inoshandura basa zvakare, oxygen inogona kuramba ichigadzirwa.
Oxygen nenitrogen zvine mapoinzi akafanana ekuvira, izvo zvinoita kuti zviome kupatsanurwa, uye zvakafumiswa pamwe chete mumhepo.Saka, psa oxygen midziyo yekugadzira oxygen inogona kazhinji kuwana 90-95% okisijeni (yakanyanya yakaipa kusangana kweokisijeni i95.6%, yasara is argon), inozivikanwawo seoxygen rich.Kuenzaniswa ne-cryogenic air separation units, iyo yekupedzisira inogona kubudisa zvinopfuura 99.5% oxygen concentration.
Device process
Iyo adsorption bed ye psa air separation oxygen plant inofanira kuva nematanho maviri ekushanda.Adsorption uye resolution.Kuti urambe uchiwana gasi rechigadzirwa, kazhinji mabhedha anopfuura maviri adsorption anoiswa mumudziyo wekugadzirwa kweokisijeni, uye kubva pamaonero ekushandiswa kwesimba uye. kugadzikana, mamwe matanho anodiwa ebetsero akaiswa.Mubhedha wega wega wekushambadza kazhinji unofanirwa kupinda adsorption, kusunungurwa kwekumanikidzwa, kubuda kana decompression regeneration, flushing replacement uye pressure equalization boost nhanho, periodic inodzokororwa oparesheni. siyana oparesheni matanho, pasi pekutonga PLC nguva chinja, kuitira kuti akati wandei adsorption mubhedha kurongeka kushanda, mukuita inodzedzereka mumwe nomumwe, kuitira kuti kumanikidzwa swing adsorption mudziyo anogona kumhanya zvakanaka, kuenderera kuwana chigadzirwa gasi. inofanirawo kutariswa kune chaiyo yekuparadzanisa maitiro.Carbon dioxide uye mvura mune yakajairwa adsorbent adsorption kugona kazhinji yakakura kwazvo kupfuura nitrogen neokisijeni, inogona kuzadzwa mumubhedha weadsorption neakakodzera adsorbent (kana kushandiswa kweokisijeni adsorbent pachayo) kuigadzira. adsorption uye kubvisa.
Huwandu hwe adsorption shongwe dzinodiwa neakisijeni yekugadzira mudziyo zvinoenderana nehukuru hwekugadzirwa kweokisijeni, adsorbent kuita uye maitiro ekugadzira mazano.Kugadzikana kwekushanda kwe-multi-tower operation kuri nani, asi mari yemidziyo yakakwira.Maitiro azvino ndeekushandisa maokisijeni emushonga wepamusoro-kurerutsa kuwanda kweshongwe dzeadsorption uye kushandisa mapfupi ekushandisa kuwedzera kushanda kwechirimwa uye kuderedza mari. .
Unyanzvi hunoita
1. Nyore nzira kuyerera mudziyo
2. chiyero chekugadzirwa kweokisijeni pasi pe10000m3 / h, kushandiswa kwesimba rekugadzirwa kweokisijeni kwakaderera, kushoma mari;
3 huwandu hweinjiniya yehurumende idiki, kutenderera kutenderera kwechigadzirwa kupfupi pane cryogenic mudziyo;
4. Mutengo wakaderera wekushanda kwechigadzirwa nekugadzirisa;
5. dhigirii yakakwira yeautomation yekushanda kwechishandiso, nyore uye nekukurumidza kutanga uye kumira, vashoma vashandisi;
6. kushanda kwechigadzirwa chacho kwakagadzikana uye kwakachengeteka;
7. kushanda kuri nyore, zvikamu zvikuru zvinosarudzwa pasi rose vanozivikanwa vagadziri;
8. kushandisa yekutanga kunze kwenyika oxygen molecular sieve, kushanda kwepamusoro uye hupenyu hurefu hwebasa;
9. kushanduka kwakasimba kwekushanda (yepamusoro mutoro mutsetse, kukurumidza kutendeuka kukurumidza).
