Bambanci tsakanin VPSA oxygen janareta da PSA oxygen janareta

Kololuwar da ta dace, VPSA (ƙananan ƙarar matsa lamba) samar da iskar oxygen wani “bambance-bambancen” naPSA samar da oxygen, ka'idodin samar da iskar oxygen ɗin su kusan iri ɗaya ne, kuma cakuda iskar gas ya rabu ta hanyar bambance-bambancen ikon sieve na ƙwayoyin cuta don "adsorb" ƙwayoyin iskar gas daban-daban. Amma tsarin samar da iskar oxygen na PSA shine ta hanyar adsorption na matsa lamba, lalata yanayin yanayi don raba iskar oxygen. Tsarin VPSA na samar da iskar oxygen shine don ɓata cikakken sieve na ƙwayoyin cuta a ƙarƙashin yanayi mara kyau.

Kodayake duka biyu sun dogara ne akan iska a matsayin albarkatun kasa, ka'idar samar da iskar oxygen yana kama da haka. Amma idan aka kwatanta da hankali, akwai bambance-bambance masu zuwa;

1. TheVPSA oxygen janaretayana amfani da na'urar busa don samun danyen iska da matse shi, yayin da na'urar samar da iskar oxygen ta PSA ke amfani da injin damfara don samar da iskar gas.

2, A cikin core bangaren - zeolite kwayoyin sieve selection, PSA oxygen janareta yana amfani da sodium kwayoyin sieve da VPSA oxygen janareta yana amfani da lithium kwayoyin sieve.

3. Matsayin adsorption na janareta na oxygen na PSA yawanci shine 0.6 ~ 0.8Mpa, kuma matsa lamba na VPSA oxygen janareta shine 0.05Mpa kuma matsa lamba na desorption shine -0.05Mpa.

4, PSA guda shuka gas samar iya aiki iya isa 200 ~ 300Nm³ / h, da kuma VPSA guda shuka gas samar iya aiki iya isa 7500 ~ 9000Nm³/h.

5, VPSA dangane da PSA, ƙananan amfani da makamashi (samar da 1Nm3 iskar oxygen amfani ≤ 0.31kW, oxygen tsarki 90%, ba tare da oxygen matsawa), kuma mafi muhalli abokantaka.

6, Dangane da samar da iskar oxygen, ka'idojin amfani da makamashi da saka hannun jari don zaɓin tsarin PSA ko tsarin VPSA.

VPSA oxygen janareta ko da yake guda shuka oxygen samar iya aiki ne babba, amma ta kasawa shi ne cewa tsarin kayan aiki ne mafi hadaddun, da girma na kayan aiki ne ya fi girma (kwatanta da cryogenic na'urar ne har yanzu karami), goyon baya da kuma utilities yanayi ne mafi bukata. , zai mamaye sarari mafi girma, gabaɗaya ba za a iya sanya shi cikin sigar akwati ba. Kuma yana buƙatar shigarwa a kan-site, ƙaddamarwa, daga wannan batu kadai. PSA yana da wasu fa'idodi.
