Industrial oxygen jenaretatora zeolite molecular sieve se adsorbent uye shandisa iyo yekumanikidza adsorption, pressure desorption musimboti kubva kumhepo adsorption uye kuburitsa okisijeni. Zeolite molecular sieve imhando yespherical granular adsorbent ine micropores pamusoro uye mukati, uye ichena. Maitiro ayo ekupfuura anoigonesa kuwana kinetic kupatsanurwa kweO2 uye N2. Iyo yekuparadzanisa mhedzisiro yezeolite molecular sieve paO2 neN2 yakavakirwa pamusiyano mudiki wekinetic madhayamita emagasi maviri. N2 molecule ine kukurumidza kupararira mwero mumakropores e zeolite molecular sieve, nepo O2 molecule ine inononoka kupararira mwero. Kupararira kwemvura uye CO2 mumhepo yakamanikidzwa haina kunyanya kusiyana neiyo nitrogen. Izvo zvinozobuda kunze kweiyo adsorption tower mamorekuru eokisijeni. Pressure swing adsorptionkugadzirwa kweokisijeniiko kushandiswa kwezeolite molecular sieve kusarudzwa adsorption maitiro, kushandiswa kwekumanikidza adsorption, desorption cycle, iyo yakamanikidzwa mhepo inopindirana mune adsorption tower kuti iwane kupatsanurwa kwemhepo, kuitira kuti irambe ichiburitsa okisijeni.
1. Yakadzvanywa mweya yekuchenesa unit
Iwo mweya wakadzvanywa wakapihwa nemhepo compressor unotanga wapfuudzwa muyakadzvanywa mweya yekuchenesa chikamu, uye mweya wakamanikidzwa unotanga wabviswa nepombi sefa yakawanda yemafuta, mvura uye guruva, uye yozobviswazve neyakaomeswa nechando, iyo yakanaka sefa. yekubvisa mafuta uye kubvisa guruva, uye iyo yekupedzisira-yakanaka sefa inoteverwa nekunatswa kwakadzika. Zvinoenderana nehurongwa hwekushanda, TCWY yakanyatso gadzira seti yakamanikidzwa yemhepo degreaser kudzivirira inogona kuteedzera kupinda kwemafuta uye nekupa dziviriro yakakwana kune molecular sieve. Yakanyatsogadzirirwa zvinhu zvekuchenesa mweya zvinovimbisa hupenyu hwesevhisi ye molecular sieve. Mhepo yakachena inobatwa negungano iri inogona kushandiswa kumhepo yemidziyo.
2. Tangi yekuchengetedza mhepo
Basa rekuchengetedza mhepo tangi ndere: kuderedza kuyerera kwemhepo, kutamba basa rebuffer; Saka, kudzvinyirirwa kushanduka kwehurongwa kunoderedzwa, kuitira kuti mhepo yakamanikidzwa inopfuura nepakati yakamanikidzwa yekuchenesa mhepo chikamu zvakanaka, kuitira kuti ibvise zvakakwana mafuta nemvura inosvibisa, uye kuderedza mutoro weinotevera PSA okisijeni uye nitrogen kupatsanura mudziyo. Panguva imwecheteyo, kana iyo adsorption tower ichishandurwa, inopawo huwandu hukuru hwemhepo yakamanikidzwa yePSA okisijeni uye nitrogen yekuparadzanisa mudziyo kuti ikurumidze kuwedzera kudzvanywa munguva pfupi, kuitira kuti kudzvanywa kweiyo adsorption tower kukurumidza kusimuka. kumanikidzwa kwekushanda, kuve nechokwadi chekuvimbika uye kugadzikana kushanda kwemidziyo.
3. Okisijeni uye nitrogen yekuparadzanisa mudziyo
Iyo adsorption tower yakashongedzerwa yakakosha molecular sieve ine maviri, A uye B. Kana mweya wakachena wakadzvanywa uchipinda mujinga reshongwe A uye uchiyerera nemusefa wemolecular kusvika kumagumo ekubuda, N2 inoshambadzwa nayo, uye chigadzirwa okisijeni inoyerera ichibuda. kubva kumagumo kweiyo adsorption tower. Mushure menguva yakati rebei, iyo molecular sieve muTower A yakazadzwa neadsorption. Panguva ino, shongwe A inongomira kudsorption, mhepo yakamanikidzwa inoyerera ichipinda muShongwe B yekutora nitrogen uye kugadzirwa kweokisijeni, uye molecular sieve yeTower A inogadzirwa patsva. Kudzokororwa kwema molecular sieve kunowanikwa nekukurumidza kudonhedza adsorption tower kumhepo yekumanikidza kubvisa iyo adsorbed N2. Idzi shongwe mbiri dzakachinjika uye dzinogadziridzwa kuti dzipedze kupatsanurwa kweokisijeni nenitrogen uye nekuenderera mberi kwekubuda kweokisijeni. Aya maitiro ari pamusoro anodzorwa neanorongeka logic controller (PLC). Kana kuchena kweokisijeni yekubuda kunopera kwaiswa, chirongwa chePLC chinoshanda, iyo otomatiki vent valve inovhurwa, uye iyo isina kukwana okisijeni inodururwa otomatiki kuti ive nechokwadi chekuti iyo isina kukwana okisijeni haiyerere ichienda kunzvimbo yegesi. Kana gasi richibuda, ruzha rwuri pasi pe75dBA nekushandisa silencer.
4. Oxygen buffer tank
Iyo okisijeni buffer tank inoshandiswa kuenzanisa kudzvanywa uye kuchena kweokisijeni yakaparadzaniswa neiyo nitrogen okisijeni yekuparadzanisa system kuti ive nechokwadi chekugadzikana kwekuenderera kwekupihwa kweokisijeni. Panguva imwecheteyo, mushure mekunge basa reiyo adsorption shongwe yashandurwa, ichazadza chikamu chegasi rayo kudzoka kune adsorption tower, kune rumwe rutivi kubatsira adsorption tower kumanikidza, asi zvakare kuita basa mukudzivirira mubhedha, uye kutamba basa rinokosha zvikuru rekubatsira mukushanda kwemidziyo.
