Enwere ike ịmegharị ọrụ okirikiri na-aga n'ihu na-akpaghị aka. Ya mere, mgbe nkà na ụzụ ọhụrụ a pụta, ọ na-eche banyere ụlọ ọrụ nke mba dị iche iche, na-asọmpi ịzụlite na nyocha, mmepe ngwa ngwa, na-eto eto.
(Akụkọ nke mmepụta nitrogen psa)
Na 1960, Skarstrom tụrụ aro patent PSA. O jiri 5A zeolite molecular sieve dị ka adsorbent ma jiri ngwaọrụ PSA nwere akwa abụọ kewapụ oxygen bara ụba na ikuku. E meziri usoro a ma tinye ya na mmepụta ụlọ ọrụ na 1960s. N'afọ ndị 1980, ngwa mmepụta ihe nke teknụzụ psa nwere ọganihu ọganihu, nke etinyere na nkewa oxygen na nitrogen, ihicha ikuku na ịdị ọcha, nchacha hydrogen na ihe ndị ọzọ. N'ime ha, ọganihu nkà na ụzụ nke ikuku oxygen na nitrogen nkewa bụ nchikota nke ọhụrụ adsorbent carbon molecular sieve na nrụgide swing adsorption iji kewaa O2 na N2 na ikuku, iji nweta nitrogen.
Na mma nke arụmọrụ na àgwà nke molekụla sieve, nakwa dị ka na-aga n'ihu mma nke mgbali siwing adsorption usoro, ịdị ọcha na mgbake ọnụego nke ngwaahịa na-anọgide na-mma, nke na-eme ka nrụgide swing adsorption na mmezu nke akụ na ụba isi na mmepụta ihe.
Kemgbe mmalite nke teknụzụ PSA sitere na Dalian Chemical Research Institute, Hangzhou Boxiang Gas Company etinyela aka na nyocha, ihe ọhụrụ na mmepe nke teknụzụ PSA, na nke mbụ mere mmepụta teknụzụ na China. Hangzhou Boxiang ụlọ ọrụ na ọtụtụ afọ nke akụrụngwa
N'ime usoro mmepụta na ịzụ ahịa, etinyela ihe karịrị 1000 ngwa ngwa n'ime ọrụ mmepụta ihe na ụlọ ọrụ dị iche iche na China.
Ngwunye nitrogen sitere na ngwaọrụ na-emepụta nitrogen na-abanye na cg-6 nitrogen buffer tank ma na-enyocha ya site na bxf-16 uzuzu uzuzu iji nweta nitrogen dị ọcha na ịdị ọcha nke 98% na mkpụrụ nke 900Nm3 / h. Nrụgide mmepụta bụ ≥ 0.5mpa (nke a na-edozi), ebe ikuku ikuku bụ ≤-40 ℃, mmanụ mmanụ bụ ≤0.001 PPM, na uzuzu ọdịnaya bụ ≤0.01μm. N'ikpeazụ, nitrogen emechara na-abanye na tank nchekwa nitrogen (ahaziri dị ka onye ọrụ chọrọ) ma buru ya gaa n'ebe gas nke onye ọrụ.
Nkọwapụta njirimara njikwa akpaaka nke igwe na-emepụta nitrogen PSA
Ngwa Nitrogen na-anabata PLC S7-200 (onye na-ahụ maka mgbagha) site na SIEMENS, Germany. Ngalaba ahụ nwere arụmọrụ nke ọma na-achịkwa ma nwee ike igosipụta paramita arụ ọrụ dị iche iche, ọkwa na akara mperi nke akụrụngwa.
B. Nitrogen dị ọcha na-achọpụta na ịntanetị ozugbo. Mgbe ịdị ọcha nitrogen na-emepụta site na ngwaọrụ na-emepụta nitrogen dị ala karịa ntọala setịpụrụ (ntụgharị ịdị ọcha nitrogen nke onye ahịa chọrọ), usoro ahụ ga-ama jijiji ma tọgbọ chakoo na-akpaghị aka. Mgbe ebidochara ngwa ahụ, valvụ solenoid ga-emeghe valvụ ikuku ikuku na-akpaghị aka ma mechie valvụ ikuku nitrogen mgbe ọ nwetasịrị akara njikwa sitere na onye nyocha nitrogen. Nitrogen na-erughị eru ga-apụta ozugbo. Mgbe nitrogen dị ọcha ruru ebe a na-achọsi ike, a na-emechi valvụ ikuku iyuzucha ya na-akpaghị aka ma meghee valvụ ikuku nitrogen iji wepụta nitrogen tozuru oke. N'ime usoro eji eme ihe niile, enweghị ọrụ aka.
Ụdị C, BXN nitrogen eme ngwaọrụ na ịdị ọcha ngwaọrụ na-onwem na akpaka efu usoro, na nitrogen analyzer nwere ike ịtọ ezi nitrogen ịdị ọcha na-enye ohere ala ịgba, mgbe nitrogen ịdị ọcha bụ ala karịa set uru bụ ala ịgba usoro ụda na ìhè mkpu, na na-akpaghị aka na-emeghe iyuzucha valvụ hapụ nitrogen erughi eru ka ọ daa, mgbe laghachiri na ịdị ọcha nkịtị, valvụ efu na-emechi na-akpaghị aka, nitrogen gas site nkịtị mmepụta ọkpọkọ mmepụta.
D, pneumatic valvụ nwere mkpanaka mgbanwe mgbanwe valvụ, kensinammuo, bụ nkwa nke ọrụ a pụrụ ịdabere na ya nke akụrụngwa mmepụta nitrogen.
E, aki oyibo ute cylinder akpaka teknụzụ mkpakọ, iji na-ekwe nkwa ogologo oge na kwụsiri ike ọrụ nke nitrogen gas akụrụngwa, melite cylinder mgbali ngwaọrụ na usoro, na n'otu oge ahụ na mkpakọ usoro setịpụrụ abụọ isi ihe. na ngwaọrụ oti mkpu, ebe mbụ na nlekota mkpu mgbanwe hydroxyl njem, nke abụọ hydroxyls mkpu bụ oriri nke njikere carbon molecular sieve.
F, nitrogen na-eme ngwaọrụ na-anabata Siemens PLC S7-200 njikwa usoro na ihuenyo mmetụ njikwa njikwa, yana nlekota akụrụngwa, njikwa, mgbazi, mmepụta, mkpu mmejọ, mmalite na nkwụsị na ọrụ ndị ọzọ, na-arụ ọrụ ngosi ọtụtụ ihuenyo.
