Theelectric heat nitrogen pipeline hitasisitimu mudziyo unoshandura simba remagetsi kuita simba rinopisa kupisa nitrogen inoyerera mupombi. Yayo sisitimu dhizaini dhizaini inofanirwa kufunga nezvekudziya kupisa, kuchengetedza, uye otomatiki kutonga. Izvi zvinotevera zvikamu zvaro zvakakosha uye tsananguro dzakadzama:
1,Heating main module
1. Electric heat element
• Zvinhu zvinodziisa:
Fin type yemagetsi kudziyisa chubhu: yakagadzirwa nesimbi isina tsvina (yakadai se304 / 316L) kana yakakwirira-tembiricha alloy zvinhu, ine pamusoro yakatsikirirwa zvimbi kuti iwedzere kupisa nzvimbo yekupisa uye kunatsiridza kupisa kwekuchinjana. Iyo yemukati inogadzirwa newaya yekupikisa (nickel chromium alloy), yakazadzwa nemagnesium oxide poda (MgO) sechinhu chinodzivirira uye chinoitisa kupisa, kuve nechokwadi chekudzivirira kwemagetsi uye kupisa kwakanyanya (tembiricha yekudzivirira inogona kusvika 500 ℃ kana pamusoro).
Kuisa nzira:
Thekudziyisa machubhuakagoverwa zvakaenzana achitevedza axial kutungamira kwepombi uye anonamirwa kumadziro emukati kana ruoko rwekunze rwepombi kuburikidza nemaflange kana welding, kuve nechokwadi chekubatana kwakakwana nenzvimbo yekudziya kana nitrogen inoyerera.
Maseti akawanda ekudziya machubhu anogona kusanganiswa mune parallel/series, uye simba rekutonga rinogona kuwanikwa kuburikidza neboka rekutonga (senge matatu-nhanho kudziyisa: yakaderera, yepakati, uye yakakwirira simba).
2. Muviri wepombi
Main pipeline:
Material: Stainless simbi 304/316L (inoshingirira kuomesa nitrogen corrosion), ine 310S kana Inconel alloy inowanikwa kune yakakwirira tembiricha mamiriro.
Mamiriro: Seamless simbi pombi welding kana flange kubatana, mukati rusvingo polishing kurapwa (Ra ≤ 3.2 μ m) kuderedza gasi kuyerera kuramba, pombi dhayamita rakagadzirwa maererano nitrogen kuyerera mwero (m ³/h) uye kuyerera velocity (yakakurudzirwa 5-15m/s), mukuwirirana GB/T 18914 kana ASMEs mureza B.
• Insulation layer:
Putira chikamu chekunze nedombo reshinda kana aluminium silicate fiber, nehupamhi hwe50-100mm, uye uifukidze nesimbi isina tsvina kuti uderedze kurasikirwa kwekupisa (tembiricha yepamusoro ≤ 50 ℃).
2,Kudzora system
1. Temperature control unit
• Sensonzi:
Tembiricha yekuyera chinhu: Pt100 thermistor (chaiyo ± 0.1 ℃) kana K-mhando thermocouple (yepamusoro tembiricha kuramba ≥ 1000 ℃), yakaiswa panzvimbo inopinza uye yekubuda kwepombi uye pakati pechikamu chekudziya, kutarisa tembiricha munguva chaiyo.
Flow/pressure sensors: vortex flowmeter, thermal mass flowmeter (yekuyeresa kuyerera), pressure transmitter (yekuyeresa pressure), inoshandiswa kuverenga kudiwa kwesimba rekudziya.
• Controller:
PLC kana DCS system: Yakabatanidzwa PID algorithm, inogadzirisa otomatiki simba rekudziya zvinoenderana neyakagadzika tembiricha (senge kuburikidza ne thyristor simba regulator kana solid-state relay SSR), inotsigira kure kutarisa uye kurekodha data.
2. Magetsi ekudzora module
•Sitimu yemagetsi:
◦ Simba rekuisa: AC 380V/220V,50Hz,Gadzirisa mabreaker breakers uye anodzivirira ekudonha kuti atsigire matatu-chikamu akaenzana magetsi ekupa.
Kudzora kwesimba: Solid state relay (SSR) kana simba regulator, isingabatike switching, kukurumidza kupindura kumhanya, hupenyu hurefu.
• Chidziviriro chekuchengetedza:
Kudzivirirwa kwekushisa kwepamusoro: Yakashongedzerwa neyakavakwa-mukati bimetallic thermostat kana tembiricha switch, kana tembiricha yakayerwa ikadarika kukosha kweseti (senge 20 ℃ yakakwirira kupfuura tembiricha yakatarwa), magetsi ekudziya anobviswa nechisimba uye alarm inoridzwa.
Kuwedzeredza / kupfupika kwedziviriro yedunhu: yazvino transformer + circuit breaker kudzivirira kusaenzana kwedunhu kunokonzerwa nekupisa kwehubhu kukanganisa.
Kudzivirirwa Kudzivirirwa: Iyo yekudzvanya switch inosungirirwa kuvharika kudzivirira pombi yakawandisa (inokonzeresa kana ichipfuura 1.1 nguva yedhizaini yekumanikidza).
Inopindirana basa: Yakabatanidzwa nenitrogen sosi, kupisa kunorambidzwa kana pasina gasi kuyerera kudzivirira kupisa kuoma.
3,Zvikamu zvekubatsira
1. Batanidza uye isa zvikamu
Kupinza uye kutumira kunze maflange: RF flat flanges (PN10/PN16) inoshandiswa, iine zvinhu zvakafanana sepombi, uye yekuvharisa gasket isimbi yakaputirwa gasket kana PTFE gasket.
• Bracket nekugadzirisa zvikamu: Carbon steel galvanized kana Stainless simbi bracket, inotsigira yakatwasuka / yakatwasuka kuisirwa, ine spacing yakagadzirwa maererano nedhayamita yepombi uye inotakura mutoro (zvakadai seDN50 pipeline bracket spacing ≤ 3m).
2. Kuedza uye kugadzirisa interface
Tembiricha / kudzvanywa kuyerwa interface: Chengetedza G1/2 "kana NPT1/2" yakarukwa nzvimbo painopinza uye yekubuda kwepombi kuitira nyore disassembly uye calibration yemasensor.
• Kubuditsa mvura: DN20 vheruvhu yekuburitsa inoiswa pazasi pepombi kuti igare ichibuditsa mvura yakakonyedzwa kana tsvina (kana nitrogen iine huwandu hwemwando).
• Gomba rekuongorora: Mapaipi marefu kana zvivakwa zvakaomarara zvine mafurange ekuongorora ekuvhura anokurumidza kutsiva pombi dzekudziya uye kuchenesa madziro emukati.
4,Kuchengetedza uye Kuputika kwechiratidzo Dhizaini (kana zvichidikanwa)
Kuputika kwechiratidzo chekuyera: Kana yakashandiswa munzvimbo dzinopisa uye dzinoputika (senge petrochemical workshops), sisitimu inofanirwa kutevedzera Ex d IICT6 kuputika-proof standard, iyo yekudziya chubhu inofanirwa kuve inoputika-chiratidzo (ine kuputika-chitupa chitupa chemabhokisi ekusangana), uye zvikamu zvemagetsi zvinofanirwa kuiswa mumakabati ekudzivirira-kuputika.
Kudzivirirwa kwepasi: Iyo yese sisitimu yakavakirwa pasi (grounding kuramba ≤ 4 Ω) kudzivirira static kuunganidza magetsi uye njodzi yekudonha.
5,Yakajairika maapplication
Chemical industry: nitrogen purging, reactor preheating, drying process heat.
Indasitiri yemagetsi: Kudziya kwenitrogen kwakakwira mukugadzira semiconductor (inoda kukwenenzverwa kwemukati kuitira kudzivirira kusvibiswa).
Metallurgy/Kupisa Kurapa: Choto chinopinda kupisa, simbi inosungirirwa neinodzivirira mamiriro ekudziya.
pfupikisa
Theelectric heat nitrogen pipeline hitasisitimu yakatarisana nemagetsi ekudziya zvinhu uye inowana chaiyo tembiricha inokwira kuburikidza nehungwaru kutonga. Chimiro chayo chinoda kuenzanisa kunyatsoshanda kwemafuta, kuchengetedzeka, uye kusimba kwemvura, zvichiita kuti ive yakakodzera kune maindasitiri mamiriro anoda tembiricha, kuchena, uye kudzivirira kuputika. Paunenge uchigadzira, zvigadzirwa, magetsi ekugadzirisa, uye zvirongwa zvekutonga zvinofanira kusarudzwa zvichienderana nemamiriro ezvinhu chaiwo ekushanda (kuyerera kwehuwandu, tembiricha, kumanikidza, nharaunda) kuve nechokwadi chekushanda kwakasimba kwenguva refu.
Kana iwe uchida kuziva zvakawanda nezvechigadzirwa chedu, ndapotataura nesu!
