Ngā āhuatanga
1. Ka whakapau kaha a TCWY ki te hoahoa me te hanga i te tipu Pressure Swing Adsorption Plant me te mahi nui.E ai ki nga whakaritenga motuhake a nga kaihoko me nga ahuatanga whakangao, ko te mahere hangarau tino tika, te huarahi tukanga, nga momo adsorbents me te waahanga e whakaratohia ana hei whakarite i te hua o te hau whai hua me te pono o te taurangi.
2. I roto i te mahere mahi, ka mauhia te kete rorohiko whakahaere pakeke me te matatau ki te arotau i te waa whakauru, e taea ai e te tipu te mahi i roto i te tikanga tino ohaoha mo te wa roa, ka noho kore noa i te awe o te taumata hangarau me te mahi poauau o nga kaiwhakahaere. .
3. Ka whakamahia te hangarau whakaki o nga adsorbents ki te whakaheke ake i nga waahi mate i waenga i nga papa moenga me te whakanui ake i te tere whakaora o nga waahanga whai hua.
4. Ko te roanga o to tatou PSA marere programmable me nga hangarau motuhake kei runga ake i te 1 miriona wa.
(1) Tukatuka Adsorption
Ka uru atu a Feed Gas ki te pourewa adsorption mai i te raro o te pourewa (Kotahi, e hia ranei kei te ahua o te adsorbing).Na roto i te whiriwhiringa o nga momo adsorbents kotahi i muri i te kotahi, ka uru nga poke, ka rere te H2 kaore i uru mai i te tihi o te pourewa.
A, no te te tuunga whakamua o te rohe whakawhiti papatipu (te tuunga whakamua adsorption) o te poke adsorption tae te putanga i rahuitia te wāhanga o te paparanga moenga, whakawetohia te piha kai o te hau kai me te vaolo putanga o te hau hua, mutu adsorption.Na ka huri te moenga adsorbent ki te mahi whakaora.
(2) Taurite Depressurization
I muri i te tukanga adsorption, i runga i te ahunga o te adsorption hoatu teitei-pēhanga H2 i adsorption pourewa ki etahi atu raro pēhanga adsorption pourewa kua oti te whakahou.Ko te tukanga katoa ehara i te tukanga depressurization anake, engari ano hoki te tukanga mo te whakaora i te H2 o te waahi mate moenga.Kei roto i te tukanga he maha nga wa i runga i te awa te whakahekenga orite, na reira ka taea te whakaora i te H2.
(3)Pathwise Pressure Release
I muri i te rite o te tukanga depressurization, i runga i te ahunga o te adsorption te hua H2 i runga i te tihi o te pourewa adsorption ka hohoro ora ake ki te ara pehanga tuku hau pūreirei tank (PP Gas Buffer Tank), tenei wahi o H2 ka whakamahia hei puna hau whakahou o adsorbent. whakapouri.
(4) Whakamuri Whakamuri
I muri i te tukanga tuku pehanga ara, kua tae te tuunga whakamua adsorption ki te putanga o te paparanga moenga.I tenei wa, kua heke te pehanga o te pourewa adsorption ki te 0.03 barg ranei i te ahunga kino o te adsorption, ka timata te nui o nga poke adsorbed ki te desorbed i te adsorbent.Ka uru te hau whakamuri whakamuri ki roto i te taika hau hiku, ka uru ki te hau regeneration purging.
(5) Te pure
I muri i te tukanga depressurization whakamuri, i roto i te tikanga ki te riro i te whakaoranga oti o adsorbent, te whakamahi i te hauwai o te ara pehanga tuku hau buffer tank i te ahunga kino o te adsorption ki te horoi i te paparanga moenga adsorption, heke atu te pēhanga hautanga, a ka taea e te adsorbent tino. ka whakahouhia, me puhoi me te pumau tenei tukanga kia pai ai te painga o te whakaoranga.Ka uru ano te horoi o te hau whakaora i te taika hau hiku.Katahi ka tukuna atu i te tepe o te pākahiko ka whakamahia hei hau wahie.
(6)Whakariterite Repressurization
I muri i te purenga o te mahi whakahou, whakamahia te H2 teitei-pēhanga mai i tetahi atu pourewa adsorption ki te whakahou i te pourewa adsorption i roto i te hurihanga, ko tenei tukanga e rite ana ki te tukanga rite-depressurization, ehara i te mea he tukanga o te whakanui i te pehanga, engari ano hoki he tukanga whakaora H2 i roto i te moenga mokowā mate o te tahi atu pourewa adsorption.Kei roto i te tukanga he maha nga wa i runga i te awa nga tukanga pehanga rite.
(7) Hua Hau Whakamutunga Repressurization
I muri i nga wa maha nga tukanga repressurization rite, i roto i te tikanga ki te huri i te pourewa adsorption ki muri adsorption taahiraa tamau, me te ki te whakarite i te purenga hua e kore e ki te kia rerekē, me te reira ki te whakamahi i hua H2 mā te piha mana whakanui ki te whakaara i te pēhanga o te pourewa adsorption ki te pēhanga adsorption. āta haere tonu.
I muri i te tukanga, ka whakaoti nga pourewa adsorption i te huringa "adsorption-regeneration" katoa, me te whakarite mo te adsorption e whai ake nei.
