Pressure swing adsorption nitrogen / okisijeni yekugadzira maitiro
Kushanda Nheyo
Zvinoenderana nemusimboti wekumanikidza swing adsorption, iyo nitrogen jenareta inoshandisa yakakwira-mhando kabhoni molecular sieve seadsorbent kuburitsa nitrogen kubva mumhepo pasi pekumanikidza kwakati.Iyo yakacheneswa uye yakaomeswa mhepo yakamanikidzwa inoshambadzirwa pasi pekumanikidzwa uye desorbed pasi pekudzikiswa kwakaderedzwa mu adsorber.Nekuda kweiyo aerodynamic mhedzisiro, mwero wekupararira kweokisijeni mumamicropores ecarbon molecular sieve wakakwira zvakanyanya kupfuura wenitrogen.Oxygen inonyanya kushandiswa nekabhoni molecular sieve, uye nitrogen inowedzerwa muchikamu chegasi kuti iite nitrogen yapera.Zvino, mushure mekudzvinyirirwa kumhepo yemhepo, iyo adsorbent inobvisa iyo adsorbed okisijeni uye kumwe kusvibiswa kuti ione kuvandudzwa.Kazhinji, maviri adsorption shongwe akaiswa muhurongwa.Imwe shongwe idsorbs nitrogen uye imwe shongwe desorbs uye regenerates.Iyo PLC chirongwa chinodzora chinodzora kuvhurwa nekuvhara kwevhavhavha yepneumatic kuita kuti shongwe mbiri dzitenderere zvakachinjana, kuitira kuti uwane chinangwa chekuenderera mberi kwekugadzira nitrogen yemhando yepamusoro.
Kuyerera kwehurongwa
Iyo yakakwana yekugadzirwa kweokisijeni system ine zvinotevera zvikamu:
Air compressor ➜ buffer tank ➜ compressed air purification device ➜ air process tank ➜ oxygen nitrogen separation device ➜ oxygen process tank.
1. Air compressor
Semhepo sosi nemidziyo yemagetsi yejenareta yenitrogen, mhepo compressor inowanzosarudzwa sescrew muchina uye centrifuge kuti ipe mweya wakatsikirirwa wakakwana kune jenareta renitrogen kuti ive nechokwadi chekushanda kwakajairika kwejenareta renitrogen.
2. Bhafa tangi
Mabasa etangi rekuchengetedza ndeaya: kuvharidzira, kudzikamisa kudzvanywa uye kutonhora;Kuti uderedze kuchinjika kwehudzvanyiriri hwehurongwa, bvisa zvizere kusvibiswa kwemvura-mafuta kuburikidza nevhavha yepasi, ita kuti mweya wakamanikidzwa upfuure nemuchikamu chekuchenesa mweya wakamanikidzwa, uye uve nechokwadi chekushanda kwakavimbika uye kwakagadzikana kwemidziyo.
3. Yakatsikirirwa mhepo yekuchenesa mudziyo
Iwo mweya wakamanikidzwa kubva mubhafa tangi unotanga kuunzwa mumudziyo wakamanikidzwa wekuchenesa mweya.Mazhinji emafuta, mvura uye guruva zvinobviswa ne-high-efficiency degreaser, uye zvino zvinowedzera kunyoroveswa nechando chakaoma chekubvisa mvura, kubvisa mafuta uye kubviswa kweguruva nesefa yakanaka, iyo inoteverwa nekucheneswa kwakadzika.Zvinoenderana nemamiriro ekushanda kwehurongwa, hande kambani yakanyatso gadzira seti yakamanikidzwa yemhepo degreaser kudzivirira inogona kuteedzera kupinza mafuta uye nekupa dziviriro yakakwana kune molecular sieve.Iyo yakanyatsogadzirwa yekuchenesa mhepo module inovimbisa hupenyu hwesevhisi yekabhoni molecular sieve.Mhepo yakachena inobatwa neiyi module inogona kushandiswa kune gasi rekushandisa.
4. Air process tank
Basa rekuchengetedza mhepo tangi kudzikisa kuyerera kwemhepo pulsation uye buffer;Kuti kuderedze kudzvanywa kwehurongwa uye kuita kuti mweya wakatsikirirwa upfuure nepakati peyakadzvanywa yekuchenesa mhepo chikamu, kuitira kuti ibvise zvizere mafuta-mvura tsvina uye kuderedza mutoro unotevera wePSA nitrogen uye oxygen yekuparadzanisa unit.Panguva imwecheteyo, panguva yekushandurwa kwebasa reiyo adsorption tower, inopawo PSA nitrogen uye oxygen yekuparadzanisa unit ine huwandu hukuru hwemhepo yakatsikirirwa inodiwa kukurumidza kukurumidza kusimuka munguva pfupi, izvo zvinoita kuti kudzvanywa kweiyo adsorption tower kukwira kusvika. iyo yekushanda kudzvinyirira nekukurumidza, kuve nechokwadi chekuvimbika uye kugadzikana kushanda kwemidziyo.
5. Oxygen nitrogen separation unit
Kune maviri adsorption shongwe a uye B ane yakakosha kabhoni molecular sieve.Kana mweya wakachena wakadzvanywa wapinda mujinga meshongwe uye uchiyerera uchienda kumagumo kuburikidza nekabhoni molecular sieve, O2, CO2 uye H2O inoshongedzwa nayo, uye chigadzirwa nitrogen inoyerera ichibuda kubva kumagumo kweiyo adsorption tower.Mushure menguva yenguva, iyo adsorption yekabhoni molecular sieve mushongwe a yakazara.Panguva ino, shongwe inomira otomatiki adsorption, mhepo yakamanikidzwa inoyerera ichipinda muShongwe B yekutora okisijeni uye kugadzirwa kwenitrogen, uye inodzoreredza sefa yemamorekuru yeshongwe a.Kudzokororwa kwema molecular sieve kunowanikwa nekukurumidza kudzikisa adsorption tower kusvika kumhepo yemhepo uye kubvisa adsorbed O2, CO2 uye H2O.Idzi shongwe mbiri dzinoita adsorption uye kugadzirwa patsva kupedzisa okisijeni nenitrogen kupatsanurwa uye kuenderera kuburitsa nitrogen.Aya maitiro ari pamusoro anodzorwa ne programmable logic controller (PLC).Kana kuchena kwenitrogen panzvimbo yekubuditsa gasi kwaiswa, chirongwa chePLC chinovhura otomatiki vent valve kuti iburitse otomatiki iyo nitrogen isina kukodzera, kucheka iyo nitrogen isina kukodzera kubva pakuyerera ichienda kunzvimbo yekushandisa gasi, uye shandisa silencer kuderedza ruzha rwuri pazasi. 78dba panguva yekufambisa gasi.
6. Nitrogen process tank
Iyo nitrogen buffer tank inoshandiswa kudzikamisa kudzvanywa uye kuchena kwenitrogen yakaparadzaniswa neiyo nitrogen okisijeni yekuparadzanisa sisitimu kuti ive nechokwadi chakagadzikana chinoramba chiripo chenitrogen.Panguva imwecheteyo, mushure mekushandurwa kwebasa kweiyo adsorption tower, inochajazve chikamu chegasi rayo mushongwe yeadsorption, iyo isingangobatsiri kukwira kweiyo adsorption tower, asi inoitawo basa mukudzivirira mubhedha, uye inotamba. basa rinokosha zvikuru rekubatsira mubasa rekushanda kwemidziyo.
