Nitrogen muchina wekugadzira execution standard

1. Air Division Nitrogen System yeMinistry of Electronics Indasitiri: JB6427/92 Standard
2.Electrical control wiring, kuiswa: GB5226-96 kushandiswa Paint inourawa maererano neJB2536-80

Pressure Swing Adsorption. PSA kwenguva pfupi, inyowani gasi adsorption yekuparadzanisa tekinoroji, ine zvinotevera zvakanakira: ⑴ kuchena kwechigadzirwa kwakakwira. Kazhinji inogona kushanda pakamuri tembiricha uye yakaderera kumanikidzwa, mubhedha patsva pasina kudziyisa, simba rekuchengetedza hupfumi. ⑶ Midziyo iri nyore, iri nyore kushandisa uye kuchengetedza. Kuenderera mberi kutenderera kushanda kunogona kuve kwakazara otomatiki. Naizvozvo, kana iyi tekinoroji nyowani ichibuda, inoshushikana neindasitiri yenyika dzakasiyana, kukwikwidza kusimudzira nekutsvaga, kukurumidza kusimudzira, uye kuwedzera kukura.

(Nhoroondo ye psa nitrogen kugadzirwa)
Muna 1960, Skarstrom akakurudzira PSA patent. Akashandisa 5A zeolite molecular sieve se adsorbent uye akashandisa maviri-bed PSA mudziyo kuparadzanisa oxygen yakawanda kubva kumhepo. Maitiro akagadziridzwa uye akaiswa mukugadzirwa kwemaindasitiri muma1960s. Mumakore ekuma1980, kushandiswa kwemaindasitiri kwepsa tekinoroji kwakafambira mberi, kunyanya kushandiswa mukuparadzaniswa kweokisijeni nenitrogen, kuomeswa kwemhepo nekucheneswa, kucheneswa kwehydrogen uye zvichingodaro. Pakati pavo, kufambira mberi kwetekinoroji yeokisijeni uye nitrogen kupatsanurwa ndiko kusanganiswa kweiyo adsorbent kabhoni molecular sieve uye kumanikidza swing adsorption kuparadzanisa O2 neN2 mumhepo, kuitira kuti uwane nitrogen.

Nekuvandudzwa kwekuita uye kunaka kwema molecular sieve, pamwe nekuenderera mberi nekuvandudzika kwekumanikidza swing adsorption process, kuchena uye kudzoreredza mwero wezvigadzirwa zvinoramba zvichivandudzika, izvo zvinoita kuti kudzvanywa kubhejera mukuzadzikiswa kwehupfumi hwayo uye maindasitiri.

Kubva pakaunzwa tekinoroji yePSA kubva kuDalian Chemical Research Institute, Hangzhou Boxiang Gasi Kambani yakazvipira kutsvaga, kuvandudza uye kusimudzira tekinoroji yePSA, uye yekutanga kugadzira tekinoroji yeindasitiri muChina. Hangzhou Boxiang kambani mumakore mazhinji emidziyo

Mukugadzira uye kushambadzira, zvinopfuura zana seti yemidziyo yakaiswa mukushanda kwemaindasitiri mumaindasitiri akasiyana muChina.

Iyo nitrogen inobva mumudziyo wekugadzira nitrogen inopinda mu cg-6 nitrogen buffer tank uye inosefa ne bxf-16 dust filter kuti iwane nitrogen yakachena ine hutsanana hwe98% uye goho re900Nm3/h. Izvo zvinobuda zvinomanikidza ndeye ≥ 0.5mpa (inogadziriswa), nzvimbo yedova yepamhepo ndeye ≤-40 ℃, iyo yemafuta iri ≤0.001 PPM, uye guruva riri ≤0.01μm. Pakupedzisira, iyo nitrogen yakapedzwa inopinda mu nitrogen yekuchengetedza tank (yakagadzirirwa maererano nezvinodiwa nemushandisi) uye inoendeswa kunzvimbo yegesi yemushandisi.

Tsanangudzo ye otomatiki kudzora maitiro ePSA nitrogen kugadzira muchina

A. Mudziyo wekugadzira Nitrogen unotora PLC S7-200 (programmable logic controller) kubva kuSIEMENS, Germany. Iyo unit ine yakanaka inodzoreka kuita uye inogona kuratidza akasiyana ekushandisa paramita, chimiro uye kukanganisa masaini emidziyo.

B. Nitrogen kuchena kunoonekwa online munguva chaiyo. Kana iyo nitrogen kuchena inogadzirwa ne nitrogen kugadzira mudziyo yakadzikira pane yakatarwa parameter (iyo nitrogen kuchena index inodiwa nemutengi), sisitimu inozovhundutsa uye yobva yapera otomatiki. Mushure mekunge michina yatangwa, iyo solenoid valve inongovhura iyo nitrogen vent valve uye yovhara nitrogen yekubuda valve mushure mekugamuchira chiratidzo chekutonga kubva kune nitrogen analyzer. Iyo nitrogen isina kukodzera inongobuda. Kana hutsanana hwenitrogen hwasvika pachinangwa, vharuvhu yekuburitsa inovharwa yega uye vheruvhu yenitrogen inovhurwa kuti ibudise nitrogen yakafanira. Mukuita kwese kwekushandisa, hapana mashandiro emaoko.

Type C, BXN nitrogen kugadzira mudziyo uye mudziyo wekuchenesa wakashongedzerwa otomatiki yekudurura system, pane nitrogen analyzer inogona kuseta yakanaka nitrogen kuchena inobvumira yakaderera muganho, kana iyo nitrogen kuchena kwakadzikira pane yakatarwa kukosha iri yakaderera muganhu system inzwi uye chiedza alarm, uye vhura otomatiki vharafu yekuburitsa rega nitrogen isingakodzeri ivhuvhute-pasi, kana yadzokera kune yakajairwa kuchena, vharafu yekubvisa otomatiki ichivharika, nitrogen gasi kuburikidza neyakajairika pombi yekubuda.

D, pneumatic valve ine valve switch inotungamira tsvimbo, intuitive, ndiyo vimbiso yekushanda kwakavimbika kwenitrogen kugadzira michina.

E, iyo coconut mat cylinder otomatiki compression tekinoroji, kuitira kuvimbisa kushanda kwenguva refu uye kugadzikana kweiyo nitrogen gasi midziyo, kumisikidza humburumbira yekumanikidza mudziyo muhurongwa, uye panguva imwe chete mukumanikidza system kumisa mapoinzi maviri. paaramu mudziyo, yekutanga poindi yekutarisa alarm inogadziriswa hydroxyls rwendo, yechipiri hydroxyls aramu ndiko kushandiswa kwekumira kabhoni molecular sieve.

F, nitrogen kugadzira mudziyo unotora Nokia PLC S7-200 control system uye touch screen integrated control system, ine michina yekutarisa, manejimendi, kugadzirisa, kubuda, kukanganisa alarm, kure kutanga uye kumira uye mamwe mabasa, ane akawanda-screen kuratidza basa.
