Imashini ya azote ikora ibipimo ngenderwaho
1. Sisitemu yo mu kirere Sisitemu ya Azote ya Minisiteri y’inganda za elegitoroniki: JB6427 / 92 Igipimo
2.Icyuma cyo kugenzura amashanyarazi, kwishyiriraho: GB5226-96 gushyira mubikorwa Irangi rikorwa ukurikije JB2536-80
Umuvuduko wo Kuzunguruka. PSA muri make, ni tekinoroji nshya yo gutandukanya gaz adsorption, ifite ibyiza bikurikira: pur ubuziranenge bwibicuruzwa buri hejuru. Mubisanzwe birashobora gukora mubushyuhe bwicyumba numuvuduko muke, kuvugurura uburiri udashyushye, ubukungu buzigama ingufu. Equipment Ibikoresho biroroshye, byoroshye gukora no kubungabunga. Igikorwa gikomeza cyizunguruka kirashobora kwikora rwose. Kubwibyo, iyo tekinolojiya mishya isohotse, ihangayikishijwe ninganda zibihugu bitandukanye, guhatanira kwiteza imbere nubushakashatsi, iterambere ryihuse, kandi bigenda bikura.
(Amateka yumusaruro wa azote)
Mu 1960, Skarstrom yatanze ipatanti ya PSA. Yakoresheje molekile ya 5A zeolite nka adsorbent kandi akoresha igikoresho cya PSA cyo kuryama kabiri kugirango atandukane ogisijeni ikungahaye mukirere. Inzira yaratejwe imbere ishyirwa mubikorwa byinganda mu myaka ya za 1960. Mu myaka ya za 1980, gukoresha inganda za tekinoroji ya psa byateye intambwe ishimishije, cyane cyane bikoreshwa mugutandukanya ogisijeni na azote, kumisha ikirere no kweza, kweza hydrogene nibindi. Muri byo, iterambere mu ikoranabuhanga rya ogisijeni no gutandukanya azote ni uguhuza adsorbent nshya ya karubone ya karubone hamwe na pression swing adsorption yo gutandukanya O2 na N2 mu kirere, kugirango tubone azote.
Hamwe nogutezimbere imikorere nubuziranenge bwibikoresho bya molekile, hamwe nogukomeza kunoza uburyo bwo guhinduranya umuvuduko wa adsorption, ubwiza nigarura ryibicuruzwa bikomeje gutera imbere, ibyo bigatuma umuvuduko ukabije wibikorwa byo gushyira mubikorwa ishingiro ryubukungu ninganda.
Kuva hashyirwaho ikoranabuhanga rya PSA mu kigo cy’ubushakashatsi bw’ubushakashatsi bwa Dalian, uruganda rwa gazi rwa Hangzhou Boxiang rwiyemeje gukora ubushakashatsi, guhanga udushya no guteza imbere ikoranabuhanga rya PSA, ndetse n’ambere mu gukora inganda z’ikoranabuhanga mu Bushinwa. Isosiyete ya Hangzhou Boxiang mumyaka myinshi yibikoresho
Mubikorwa byo gukora no kwamamaza, ibikoresho birenga 1000 byashyizwe mubikorwa byinganda mubikorwa bitandukanye mubushinwa.
Azote ivuye mu gikoresho cyo gukora azote yinjira mu kigega cya cg-6 cya azote kandi ikayungururwa na filteri ya bxf-16 kugirango ibone azote isukuye ifite ubuziranenge bwa 98% n'umusaruro wa 900Nm3 / h. Umuvuduko usohoka ni ≥ 0.5mpa (ushobora guhindurwa), ikime cyo mu kirere ni ≤-40 ℃, amavuta arimo ≤0.001 PPM, naho umukungugu ni ≤0.01μm. Hanyuma, azote yarangiye yinjira mububiko bwa azote (yashyizweho ukurikije ibyo umukoresha asabwa) hanyuma ikajyanwa aho gaze ikoreshwa.
Ibisobanuro biranga kugenzura byikora biranga imashini ikora azote ya PSA
A. Igikoresho cyo gukora azote cyakira PLC S7-200 (programable logic controller) kuva SIEMENS, mubudage. Igice gifite imikorere myiza igenzurwa kandi irashobora kwerekana ibipimo bitandukanye bikora, imiterere nibimenyetso byibikoresho.
B. Isuku ya azote igaragara kumurongo mugihe nyacyo. Iyo ubuziranenge bwa azote bwakozwe nigikoresho cyo gukora azote kiri munsi yikigereranyo cyashyizweho (indangagaciro ya azote isabwa n'umukiriya), sisitemu izahita ihagarika ubusa. Ibikoresho bimaze gutangira, valve ya solenoid izahita ifungura azote ya azote hanyuma ifunge azote isohoka nyuma yo kwakira ibimenyetso byo kugenzura bivuye kuri analyseur ya azote. Azote itujuje ibyangombwa izahita isohora. Iyo ubuziranenge bwa azote bugeze ku ntego, valve isohoka ihita ifungwa hanyuma azote ya azote ikingurwa kugirango isohore azote yujuje ibyangombwa. Muburyo bwose bwo gukoresha, nta gikorwa cyintoki.
Ubwoko C, BXN igikoresho cyo gukora azote hamwe nigikoresho cyo kweza gifite ibikoresho byogusohora byikora, kuri analyse ya azote irashobora gushiraho ubuziranenge bwa azote butuma imipaka igabanuka, mugihe ubuziranenge bwa azote buri munsi yagenwe ni buke buke bwa sisitemu amajwi no gutabaza, kandi mu buryo bwikora fungura umuyaga usohora reka azote yujuje ibyangombwa, iyo ugarutse mubuziranenge busanzwe, gusiba valve ihita ifunga, gaze ya azote ikoresheje imiyoboro isanzwe isohoka.
D, pneumatike valve hamwe na valve ihindura icyerekezo, intiti, ni garanti yimikorere yizewe yibikoresho bitanga azote.
E. ku gikoresho cyo gutabaza, ingingo ya mbere mugukurikirana impuruza ishobora guhinduka urugendo rwa hydroxyls, impanuka ya kabiri ya hydroxyls ni ugukoresha karubone ya karubone ihagaze.
F, igikoresho cyo gukora azote gikoresha sisitemu yo kugenzura Siemens PLC S7-200 hamwe na sisitemu yo kugenzura ikorana na sisitemu yo kugenzura, hamwe nogukurikirana ibikoresho, gucunga, gukosora, gusohora, gutabaza amakosa, gutangira kure no guhagarara nibindi bikorwa, hamwe nibikorwa byinshi byo kwerekana.
