Iubushushu bombane nitrogen umbhobho heaterinkqubo sisixhobo ukuguqula amandla ombane zibe amandla thermal ukufudumeza nitrogen equkuqelayo kumbhobho. Uyilo lwesakhiwo sayo kufuneka luthathele ingqalelo ukusebenza kakuhle kokufudumeza, ukhuseleko, kunye nolawulo oluzenzekelayo. Oku kulandelayo ngamacandelo ayo angundoqo kunye neengcaciso ezicacileyo:
1,Ukufudumeza imodyuli ephambili
1. Into yokufudumeza kombane
• Amalungu angundoqo okufudumeza:
Fin uhlobo ityhubhu yokufudumeza yombane: Yenziwe ngensimbi engenasici (efana ne-304 / 316L) okanye i-alloy-high-temperature alloy material, ene-surface fins ecinezelekileyo ukunyusa indawo yokutshatyalaliswa kobushushu kunye nokuphucula ukusebenza kakuhle kokutshintshwa kobushushu. Ingaphakathi lenziwe ngocingo lokumelana (i-nickel chromium alloy), egcwele i-magnesium oxide powder (MgO) njengento yokugquma kunye nokushisa ubushushu, iqinisekisa ukugquma kombane kunye nokumelana nobushushu obuphezulu (ukumelana nobushushu kunokufikelela kwi-500 ℃ okanye ngaphezulu).
Indlela yokuhlohla:
Iiityhubhu zokufudumezazisasazwe ngokulinganayo kwicala le-axial lombhobho kwaye zimiliselwe kudonga lwangaphakathi okanye umkhono ongaphandle wombhobho ngeeflange okanye i-welding, ziqinisekisa ukudibana okwaneleyo nomphezulu wokufudumeza xa i-nitrogen ihamba.
Iisethi ezininzi zeetyhubhu zokufudumeza zinokudibaniswa ngokuhambelana / uchungechunge, kwaye ukulawulwa kwamandla kunokufezekiswa ngokulawulwa kwamaqela (njengokufudumala kwezigaba ezintathu: okuphantsi, okuphakathi, kunye namandla aphezulu).
2. Umzimba wemibhobho
Umbhobho ongundoqo:
Izinto eziphathekayo: I-Stainless steel 304/316L (imelana ne-nitrogen corrosion), kunye ne-310S okanye i-Inconel alloy ekhoyo kwiimeko zokushisa okuphezulu.
Ulwakhiwo: Umbhobho wentsimbi engenamthungo okanye uqhagamshelo lweflange, unyango lokupolisha eludongeni lwangaphakathi (Ra ≤ 3.2 μ m) ukunciphisa ukuxhathisa ukuhamba kwegesi, ububanzi bombhobho owenziwe ngokwezinga lokuhamba kwe-nitrogen (m ³ / h) kunye nesantya sokuhamba (kucetyiswa i-5-15m / s), ngokuhambelana ne-GB / T 18984 okanye i-ASME yemigangatho ye-ASME.
• Umaleko wokugquma:
Songa umaleko wangaphandle ngoboya belitye okanye i-aluminium silicate fiber, enobunzima obuyi-50-100mm, kwaye uyigqume ngepleyiti yensimbi engenasici ukunciphisa ilahleko yobushushu (ubushushu bomphezulu ≤ 50 ℃).
2,Inkqubo yokulawula
1. Iyunithi yokulawula ubushushu
• Izivamvo:
Isixhobo sokulinganisa ubushushu: I-Pt100 thermistor (ukuchaneka ± 0.1 ℃) okanye i-K-uhlobo lwe-thermocouple (ukumelana nobushushu obuphezulu ≥ 1000 ℃), efakwe kwindawo yokungena kunye nokuphuma kombhobho kunye naphakathi kwecandelo lokufudumeza, ukujonga ubushushu ngexesha langempela.
I-Flow/pressure sensors: i-vortex flowmeter, i-thermal mass flowmeter (ukuhamba kokulinganisa), i-pressure transmitter (uxinzelelo lokulinganisa), esetyenziselwa ukubala imfuno yamandla okufudumala.
• Umlawuli:
Inkqubo ye-PLC okanye ye-DCS: I-algorithm ye-PID edibeneyo, ilungelelanisa ngokuzenzekelayo amandla okufudumeza ngokweqondo lokushisa elibekiweyo (njenge-thyristor power regulator okanye i-SSR ye-solid-state relay), isekela ukubeka iliso kude kunye nokurekhoda idatha.
2. Imodyuli yokulawula umbane
• Inkqubo yamandla:
◦ Ukufakwa kwamandla okufakwayo: AC 380V/220V,50Hz,Qwalasela ii-breakers zesekethe kunye nezikhuseli zokuvuza ukuxhasa unikezelo lwamandla olulinganayo lwezigaba ezintathu.
Ulawulo lwamandla: I-Solid state relay (SSR) okanye umlawuli wamandla, ukutshintshwa koqhagamshelwano, isantya sokuphendula ngokukhawuleza, ubomi obude.
• Isixhobo sokhuselo lokhuseleko:
Ukukhuselwa kobushushu obugqithisileyo: Uxhotyiswe nge-bimetallic thermostat eyakhelwe-ngaphakathi okanye utshintsho lobushushu, xa ubushushu obulinganisiweyo budlula ixabiso elibekiweyo (elifana ne-20 ℃ ngaphezu kobushushu obujoliswe kuyo), umbane wokufudumeza ucinywa ngenkani kwaye i-alamu iyavuswa.
Ukhuseleko olugqithileyo/ olufutshane lwesekethe: i-transformer yangoku + isaphuli sesekethe ukunqanda ukungahambi kakuhle kwesekethe okubangelwa ziimpazamo zetyhubhu yokufudumeza.
Ukukhuselwa koxinzelelo: Ukutshintshwa koxinzelelo kuxhunywe ukuvala ukuthintela ukunyanzeliswa kombhobho (okubangelwa xa kudlula amaxesha e-1.1 kuxinzelelo loyilo).
Umsebenzi odibeneyo: Udibaniswa nomthombo we-nitrogen, ukufudumeza akuvumelekanga xa kungekho gesi ukuphepha ukutshisa okomileyo.
3,Amacandelo ancedisayo
1. Qhagamshela kwaye ufake amacandelo
Iiflange zokungenisa nokuthumela ngaphandle: Iiflange ezisicaba zeRF (PN10/PN16) zisetyenziswa, zinemathiriyeli efanayo neyombhobho, kwaye igasket yokutywina yigasket esongiweyo yesinyithi okanye i-PTFE gasket.
• Isibiyeli kunye neendawo zokulungisa: Isibiyeli sentsimbi yekhabhoni eyenziwe ngamagalvanized okanye intsimbi engatyiwa, exhasa ufakelo oluthe tye/othe nkqo, kunye nesithuba esiyilwe ngokwedayamitha yombhobho kunye nomthamo wokuthwala umthwalo (ofana nesithuba se-DN50 sesibiyeli semibhobho ≤ 3m).
2. Ujongano lovavanyo kunye nokugcinwa
Ujongano lobushushu/loxinzelelo lomlinganiselo: Ugcino G1/2 "okanye NPT1/2" ujongano oluthungelwe kwindawo yokungena kunye nokuphuma kombhobho ukwenzela ukuqhawuka lula kunye nokulinganisa izinzwa.
• Indawo yokukhupha: Ivalve ye-DN20 yokukhupha ifakwe ezantsi kumbhobho ukuze kukhutshelwe rhoqo amanzi ajiyileyo okanye ukungcola (ukuba initrogen inomlinganiselo wokufuma).
• Umngxuma wokuhlola: Imibhobho emide okanye izakhiwo ezintsonkothileyo zixhotyiswe ngeeflange ezikhawulezayo zokuhlola ukuvuleka ukuze kutshintshelwe lula imibhobho yokufudumeza nokucoca iindonga zangaphakathi.
4,Ukhuseleko kunye noYilo lobungqina bokudubula (ukuba kuyafuneka)
Ukulinganisa ubungqina bokudubula: Ukuba isetyenziswe kwindawo ezinokutsha kunye neziqhushumbisi (ezifana neeworkshops zepetrochemical), inkqubo kufuneka ihambelane ne-Ex d IICT6-standard-proof-proof standard, ityhubhu yokufudumeza kufuneka ikhuseleke ukuqhuma (kunye nesiqinisekiso sobungqina bokuqhuma kwiibhokisi zesiphambuka), kunye namalungu ombane kufuneka afakwe kwiikhabhathi zokulawula ukuqhuma.
Ukukhuselwa komgangatho: Inkqubo yonke isekelwe ngokuthembekileyo (ukumelana nomgangatho ≤ 4 Ω) ukukhusela ukuqokelelwa kombane we-static kunye nobungozi bokuvuza.
5,Usetyenziso oluqhelekileyo
