Thelantarki dumama nitrogen bututun dumamaSystem wata na'ura ce da ke juyar da makamashin lantarki zuwa makamashin thermal don dumama nitrogen dake gudana a cikin bututun. Tsarin tsarin tsarin sa yana buƙatar yin la'akari da ingancin dumama, aminci, da sarrafawa ta atomatik. Wadannan su ne ainihin abubuwan da ke tattare da shi da cikakkun bayanai:
1,Babban tsarin dumama
1. Kayan wutar lantarki
• Mahimman abubuwan dumama:
Nau'in Fin lantarki bututun dumama: Ya yi da bakin karfe (kamar 304/316L) ko kayan gami da zafin jiki mai zafi, tare da filaye da aka matse don ƙara yanki mai zafi da haɓaka haɓakar canjin zafi. Cikin ciki an yi shi da waya mai juriya (nickel chromium alloy), cike da magnesium oxide foda (MgO) a matsayin kayan haɓakawa da zafi, yana tabbatar da rufin lantarki da juriya mai zafi (juriya na zafi zai iya kaiwa 500 ℃ ko sama).
Hanyar shigarwa:
Thedumama bututuana rarraba su daidai gwargwado tare da jagorar axial na bututun kuma an daidaita su zuwa bangon ciki ko hannun riga na bututun ta hanyar flanges ko walda, tabbatar da isasshen lamba tare da yanayin dumama lokacin da nitrogen ke gudana.
Za'a iya haɗa nau'ikan bututu masu dumama a layi daya / jeri, kuma ana iya samun tsarin ikon ta hanyar sarrafa rukuni (kamar dumama mataki uku: ƙananan, matsakaici, da babban iko).
2. Jikin bututu
Babban bututu:
Material: Bakin karfe 304/316L (mai jurewa bushewar lalata nitrogen), tare da 310S ko inconel gami don yanayin yanayin zafi mai girma.
Tsarin: Sumul karfe bututu waldi ko flange dangane, ciki bango polishing jiyya (Ra ≤ 3.2 μ m) don rage gas kwarara juriya, bututu diamita tsara bisa ga nitrogen kwarara kudi (m ³ / h) da ya kwarara gudun (shawarar 5-15m / s), a yarda da GB / T 189814 ko ASME misali B.
• Layer na rufi:
Rufe saman saman da dutsen ulu ko aluminum silicate fiber, tare da kauri na 50-100mm, da kuma rufe shi da bakin karfe farantin don rage zafi hasãra (surface zazzabi ≤ 50 ℃).
2,Tsarin sarrafawa
1. Naúrar kula da zafin jiki
• Sensors:
Ma'aunin ma'aunin zafin jiki: Pt100 thermistor (daidaicin ± 0.1 ℃) ko nau'in thermocouple K-nau'in (juriya mai girma ≥ 1000 ℃), wanda aka shigar a mashigar da mashigar bututun da kuma tsakiyar sashin dumama, don saka idanu zazzabi a ainihin lokacin.
Na'urori masu aunawa / matsa lamba: vortex flowmeter, thermal mass flowmeter (aunawa kwarara), matsa lamba (aunawa matsa lamba), amfani da su lissafin dumama bukatar ikon.
• Mai sarrafawa:
Tsarin PLC ko DCS: Haɗin PID algorithm, yana daidaita wutar lantarki ta atomatik bisa ga saita zafin jiki (kamar ta hanyar mai sarrafa wutar lantarki ta thyristor ko SSR mai ƙarfi mai ƙarfi), yana goyan bayan saka idanu mai nisa da rikodin bayanai.
2. Tsarin sarrafa wutar lantarki
• Tsarin wutar lantarki:
◦ Input wutar lantarki: AC 380V/220V,50Hz,Saita masu watsewar kewayawa da masu kare zubewa don tallafawa madaidaitan samar da wutar lantarki mai kashi uku.
Ikon wutar lantarki: Relay State Relay (SSR) ko mai sarrafa wutar lantarki, sauyawa mara lamba, saurin amsawa, tsawon rayuwa.
• Na'urar kariya ta tsaro:
Kariyar zafin jiki: An sanye shi da ginannen ma'aunin zafi da sanyio na bimetallic ko canjin zafin jiki, lokacin da zafin jiki da aka auna ya wuce ƙimar da aka saita (kamar 20 ℃ sama da zafin da aka nufa), ana kashe wutar lantarki da ƙarfi kuma ana kunna ƙararrawa.
Kariyar da'ira ta wuce kima/gajere: mai canzawa na yanzu + mai katsewar kewayawa don hana rashin daidaituwar da'ira da ke haifar da kurakuran bututun dumama.
Kariyar matsa lamba: An haɗa maɓallin matsa lamba don rufewa don hana yawan bututun bututu (wanda ya haifar da lokacin da ya wuce sau 1.1 na ƙira).
Ayyukan haɗin gwiwa: Haɗe tare da tushen nitrogen, an hana dumama lokacin da babu kwararar iskar gas don guje wa bushewar ƙonewa.
3,Abubuwan taimako
1. Haɗa kuma shigar da sassan
Shigo da fitarwa flanges: RF lebur flanges (PN10/PN16) Ana amfani da, da abu daya da bututun, da sealing gasket ne karfe nade gasket ko PTFE gasket.
• Bracket da gyara sassa: Carbon karfe galvanized ko bakin karfe, goyon bayan shigarwa a kwance / tsaye, tare da tazarar da aka ƙera bisa ga diamita na bututu da ƙarfin ɗaukar nauyi (kamar DN50 tazarar bututun bututu ≤ 3m).
2. Gwaji da kulawa da dubawa
Ma'aunin zafin jiki / matsa lamba: Reserve G1/2 "ko NPT1/2" masu zaren musaya a mashigin da mashigar bututun don sauƙin rarrabawa da daidaita na'urori masu auna firikwensin.
• Wurin fitarwa: Ana shigar da bawul ɗin fitarwa na DN20 a ƙasan bututun don fitar da ruwa mai ƙyalƙyali ko ƙazanta (idan nitrogen ya ƙunshi adadin danshi).
• Ramin dubawa: Dogayen bututun mai ko hadaddun sifofi suna sanye take da flanges dubawa mai sauri don sauƙin maye gurbin bututun dumama da tsaftace bangon ciki.
4,Zane-zanen Tsaro da Fashewa (idan an buƙata)
Ƙimar tabbatar da fashewa: Idan aka yi amfani da shi a cikin wurare masu ƙonewa da abubuwan fashewa (irin su wuraren bita na petrochemical), dole ne tsarin ya bi daidaitattun ƙa'idodin fashewar fashewar Ex d IICT6, bututun dumama ya zama hujjar fashewa (tare da takaddun shaida na fashewa don akwatunan haɗin gwiwa), kuma ya kamata a shigar da kayan lantarki a cikin ɗakunan ajiya mai tabbatar da fashewa.
Kariyar ƙasa: Gabaɗayan tsarin yana da dogaro mai ƙarfi (juriya na ƙasa ≤ 4 Ω) don hana tarawar wutar lantarki da haɗarin yabo.
5,Aikace-aikace na yau da kullun
Chemical masana'antu: nitrogen purging, reactor preheating, bushewa tsari dumama.
Masana'antar Lantarki: Babban dumama nitrogen mai tsabta a masana'antar semiconductor (yana buƙatar goge bangon ciki don guje wa gurɓatawa).
Metallurgy/Maganin zafi: dumama shigar tanderu, ƙarar ƙarfe tare da dumama yanayi mai karewa.
taƙaitawa
Thelantarki dumama nitrogen bututun dumamatsarin yana kewaye da abubuwan dumama wutar lantarki kuma yana samun madaidaicin hawan zafin jiki ta hanyar sarrafa hankali. Tsarinsa yana buƙatar daidaita ingantaccen yanayin zafi, aminci, da haɓaka haɓakar ruwa, yana mai da shi dacewa da yanayin masana'antu waɗanda ke buƙatar zafin jiki, tsabta, da rigakafin fashewa. Lokacin tsarawa, kayan aiki, daidaitawar wutar lantarki, da tsare-tsaren sarrafawa ya kamata a zaɓa bisa ƙayyadaddun yanayin aiki (yawan kwarara, zazzabi, matsa lamba, yanayi) don tabbatar da kwanciyar hankali na dogon lokaci.
Idan kuna son ƙarin sani game da samfuranmu, don Allahtuntube mu!
