VPSAO vakuyumu kuthamanga kugwedezeka adsorption mpweya kupanga zida

Kufotokozera Kwachidule:

Zigawo zikuluzikulu mu mlengalenga ndi nayitrogeni ndi mpweya, ntchito yozungulira kutentha, nayitrogeni ndi mpweya mu mpweya zeolite molecular sieve (ZMS) adsorption ntchito ndi osiyana (oxygen akhoza kudutsa ndi nayitrogeni adsorption), kupanga njira yoyenera, ndi kupanga nayitrogeni ndi mpweya kulekana kuti mpweya.

Zigawo zazikulu mu mlengalenga ndi nayitrogeni ndi mpweya, ntchito yozungulira kutentha, nayitrogeni ndi mpweya mu mpweya zeolite molecular sieve (ZMS) adsorption ntchito ndi osiyana (oxygen akhoza kudutsa ndi nayitrogeni adsorption), kupanga ndondomeko yoyenera, ndi kupanga nayitrogeni ndi mpweya kulekana kupeza oxygen. pamene kuthamanga kwa mpweya mu dziko lomwe lili ndi zeolite molecular sieve adsorbent adsorption bedi, nayitrogeni ndi molecular sieve adsorption, mpweya wochepa ndi adsorption, ndende ndi kuyenda mu mpweya gawo adsorption bedi, mpweya ndi nayitrogeni kulekana kwa mpweya. adsorption nayitrogeni kusintha kuthetsedwa, maselo sieve kusinthika ndipo akhoza reused.When awiri kapena kuposa mabedi adsorption kusinthana ntchito nayenso, mpweya akhoza mosalekeza kupangidwa.

Oxygen ndi nayitrogeni ali ndi mfundo zowira zofanana, zomwe zimapangitsa kuti zikhale zovuta kuzilekanitsa, ndipo zimalemeretsedwa pamodzi mumlengalenga.Choncho, zipangizo zopangira mpweya wa psa nthawi zambiri zimatha kupeza 90-95% mpweya (oksijeni woipa kwambiri ndi 95.6%, ena onse ndi argon), omwe amadziwikanso kuti oxygen olemera.

Chipangizo ndondomeko

The adsorption bed of psa air separation oxygen plant should be the two operation steps.Adsorption and resolution.Kuti mupitirize kupeza mpweya wa mankhwala, kawirikawiri mabedi oposa awiri adsorption amaikidwa mu chipangizo chopangira mpweya, ndipo kuchokera kumaganizo akugwiritsa ntchito mphamvu ndi kukhazikika, njira zina zofunika zothandizira zimakhazikitsidwa. kusinthika, kuwotcha m'malo ndi kuthamanga equalization kulimbikitsa masitepe, nthawi mobwerezabwereza operation.Pa nthawi yomweyo, aliyense adsorption bedi ndi motero mu masitepe osiyana ntchito, pansi pa ulamuliro wa PLC nthawi lophimba, kuti angapo adsorption bedi anagwirizana ntchito, mchitidwe ndi staggered wina ndi mzake, kotero kuti kuthamanga kugwedezeka adsorption chipangizo akhoza kuthamanga bwino, mankhwala gasther ayenera kuganiziridwa mopitirira muyeso mankhwala, mosalekeza kupeza mpweya. kulekana ndondomeko.Carbon dioxide ndi madzi mwachizolowezi adsorbent adsorption mphamvu zambiri zazikulu kuposa nayitrogeni ndi mpweya, akhoza kudzazidwa mu adsorption bedi ndi adsorbent yoyenera (kapena ntchito mpweya adsorbent palokha) kuti adsorption ndi kuchotsa.

Kuchuluka kwa nsanja za adsorption zomwe zimafunidwa ndi chipangizo chopangira okosijeni zimatengera kukula kwa okosijeni, machitidwe a adsorbent ndi malingaliro opangira. Kukhazikika kwa magwiridwe antchito a nsanja zambiri ndikwabwinoko, koma ndalama zogulira zida ndizokwera kwambiri.Mchitidwe wapano ndi kugwiritsa ntchito ma sorbents a oxygen okwera kwambiri kuti achepetse kuchuluka kwa nsanja za adsorption ndikugwiritsa ntchito njira zazifupi zogwirira ntchito kuti ziwonjezeke bwino mbewu ndikuchepetsa ndalama.

Makhalidwe aukadaulo

1. Njira yosavuta yoyendera chipangizocho

2. Sikelo yopanga okosijeni pansi pa 10000m3/h, kugwiritsa ntchito mphamvu zopangira okosijeni ndikotsika, ndalama zochepa;

3 kuchuluka kwa zomangamanga ndi zazing'ono, unsembe mkombero wa chipangizo ndi wamfupi kuposa chipangizo cryogenic;

4. Mtengo wotsika wa ntchito ndi kukonza chipangizo;

5. mkulu mlingo wa zochita zokha za chipangizo ntchito, yabwino ndi mwamsanga kuyamba ndi kuyimitsa, opareshoni ochepa;

6. ntchito ya chipangizocho ndi yokhazikika komanso yotetezeka;

7. ntchitoyo ndi yosavuta, zigawo zikuluzikulu zimasankhidwa opanga odziwika padziko lonse;

8. kugwiritsa ntchito sieve ya oxygen yochokera kunja, magwiridwe antchito apamwamba komanso moyo wautali wautumiki;

9. kusinthasintha kwamphamvu kwa ntchito (mzere wapamwamba kwambiri, liwiro lotembenuka mwachangu).
