Umklamo owenziwe ngokwezifiso Izifudumezi zamapayipi kagesi zokushisisa igesi yemfucuza yezimboni

Idizayini eyenziwe ngokwezifiso Izifudumezi zamapayipi kagesi zokushisisa igesi yemfucuza yezimboni Isithombe esifakiwe

Incazelo emfushane:

I-heater yamapayipi kagesi iyisisetshenziswa sokushisisa sikagesi esifakwe ngokuqondile epayipini ukuze sishise ngendlela efanele futhi ngokunembile indawo ephakathi nendawo (ikakhulukazi igesi) egeleza ngaphakathi kwepayipi. Isetshenziswa kabanzi emkhakheni wezimboni ngenxa yesakhiwo sayo esihlangene, ukusebenza kahle okuphezulu kokushisa, nokulawula okunembile.

Isingeniso Somkhiqizo

Izifudumezi zamapayipi kagesi zokushisisa igesi edoti yasezimbonini iyisisetshenziswa esisebenza kahle nesihlangene sikagesi esifakwe ngqo kumapayipi. Umsebenzi wawo oyinhloko uwukushisa ngokunembile nangokushesha igesi yemfucuza yezimboni egeleza epayipini ukuze kuhlangatshezwane nezimo zokushisa ezidingekayo zokwelashwa kwezinqubo ezilandelayo (njengokunciphisa i-catalytic, desulfurization kanye ne-denitrification), noma ukuqinisekisa ukuthi ukukhishwa kwegesi engcolile kuyahlangabezana nezindinganiso zemvelo (ukuvimbela ukwakheka kwentuthu emhlophe nenkungu ye-asidi).

Isimiso sokusebenza

PI-ipeline heater kagesi iyithuluzi elisebenzisa amandla kagesi ukuze liwaguqule libe amandla ashisayo okufudumeza okudingayo. Ngesikhathi sokusebenza, uketshezi olunezinga lokushisa eliphansi lungena endaweni yalo ngaphansi kwengcindezi, lugeleze eziteshini ezithile zokushintshanisa ukushisa ngaphakathi komkhumbi wokushisisa kagesi, futhi lulandela indlela eklanywe ngokusekelwe ezimisweni ze-thermodynamics eziwuketshezi, zithwala amandla okushisa aphakeme okushisa akhiqizwa izinto zokushisisa zikagesi, ngaleyo ndlela andise izinga lokushisa lendawo eshisisayo I-outlet ye-heater kagesi ithola okuphakathi okudingekayo ngenqubo yokushisa ephezulu. Isistimu yokulawula yangaphakathi ye-heater kagesi ilawula ngokuzenzakalelayo amandla okukhishwa kwe-heater ngokusho kwesignali yenzwa yokushisa ekuphumeni, ukugcina izinga lokushisa elilinganayo le-medium at outlet; lapho into yokushisisa ishisa ngokweqile, idivayisi yokuvikela ngaphezu kwesici sokushisa inqamula ngokushesha amandla okushisa, ivimbele okokushisisa ekushiseni ngokweqile, okubangela i-coke, ukuwohloka, kanye ne-carbonization, kanye nezimo ezinzima, okubangela ukuthi isici sokushisisa sishise, sinwebe ngempumelelo impilo yesevisi ye-heater kagesi.

Inzuzo Yomkhiqizo

I-1.Ukulawula ukushisa okunembile: Ukulawulwa okuhlakaniphile kwe-PID kwamukelwa, ngokunemba kokulawula izinga lokushisa eliphezulu (kufika ku-±1℃) kanye nesivinini sokuphendula ngokushesha.

I-2.Ukusebenza kahle kwe-thermal: Ukushisa ngokuqondile okuphakathi, amandla okushisa agxilwe epayipini, futhi ngokufakwa okuhle, ukusebenza kahle kokushisa kungafinyelela ngaphezu kwama-95%.

I-3.Isakhiwo se-Compact, ukufakwa kalula: kungaxhunywa ngokuqondile nge-flange noma kufakwe kumapayipi, ngaphandle kwesidingo sezinhlelo zokushisa eziyinkimbinkimbi kanye namapayipi.

I-4.Izinga eliphezulu lokuzenzekelayo: kulula ukuhlanganisa nezinhlelo zokulawula ezimaphakathi ezifana ne-PLC, ukufeza ukusebenza okuzenzakalelayo ngokugcwele, ukuqapha okukude, nokuvikelwa okuhlanganisiwe.

5.Ukungangcoli: Ukushisisa okuhlanzekile kukagesi, akukho mikhiqizo evuthayo, kuhlanzekile futhi kuhambisana nemvelo.

I-6.Ukuqala okusheshayo: Uma kuqhathaniswa nokushisa kwe-steam noma amafutha ashisayo, ama-heaters kagesi angaqala futhi ame ngokushesha.

Imininingwane yomkhiqizo iyaboniswa

IaI-ir circulation pipeline heater yakhiwe izingxenye ezimbili: umzimba kanye nesistimu yokulawula.Isici sokushisisa ngogesi siphehla ukushisa: Isici sokushisa sikagesi ku-heater siyingxenye eyinhloko yokukhiqiza ukushisa. Lapho amandla kagesi edlula kulezi zakhi, akhiqiza ukushisa okukhulu.

Ukushisisa okuphoqiwe kwe-convection: Uma i-nitrogen noma enye into ephakathi idlula ku-heater, isiphephetha-moya sisetshenziselwa ukuphoqa ukuguquguquka, ukuze okuphakathi kugeleze futhi kudlule endaweni yokushisisa. Ngale ndlela, i-medium, njengesithwali sokushisa, ingakwazi ukudonsa ngokuphumelelayo ukushisa futhi idlulisele ohlelweni oludinga ukushiswa.

Ukulawula izinga lokushisa: I-heater ifakwe isistimu yokulawula ehlanganisa inzwa yokushisa nesilawuli se-PID. Lezi zingxenye zisebenza ndawonye ukuze zilungise ngokuzenzakalelayo amandla okukhishwa kwe-heater ngokuvumelana nezinga lokushisa eliphumayo, ukuqinisekisa ukuthi izinga lokushisa eliphakathi lizinzile ngenani elimisiwe.

Ukuvikela ukushisa ngokweqile: Ukuze uvimbele ukulimala kokushisa okweqile kusici sokushisa, i-heater nayo ifakwe izinto zokuvikela ukushisa ngokweqile. Ngokushesha lapho kutholakala ukushisa ngokweqile, idivayisi inqamula ngokushesha ukunikezwa kwamandla, ivikela isici sokushisa kanye nesistimu.

Isici somkhiqizo

1.Isebenza kahle futhi iyonga amandla: Amandla kagesi aguqulwa ngokuqondile abe amandla ashisayo ngokusebenza okuphakeme kokuguqulwa (ngokuvamile>95%). Idizayini enhle ye-insulation iphinde yehlise ukulahleka kokushisa.

I-2.Ukulawula ukushisa okunembile: Ukulawulwa kwe-PID kungafinyelela ukunemba kokulawula izinga lokushisa kwe-± 1 ° C, ukuhlangabezana nezidingo eziqinile zenqubo.

3.Impendulo esheshayo: Ukushisisa ngogesi kuqala ngokushesha futhi izinga lokushisa lokwenyuka nokuwa liyashesha kakhulu.

4.Ihlanzekile futhi ihambisana nemvelo: Akukho nqubo yokuvutha, akukho gesi yokukhipha umoya, intuthu noma amalangabi akhiqizwayo, futhi indawo yokusebenza ihlanzekile.

5.Kulula ukuzenzela: Kulula ukuhlanganisa ezinhlelweni ze-PLC/DCS zokuqapha okukude nokulawula okuzenzakalelayo.

6.Kulula ukufaka: ngokuvamile ixhunywe nge-flange futhi ixhunywe epayipiningqo.

7.Idizayini eguquguqukayo: Amandla, usayizi, kanye nesakhiwo (njengohlobo lokuvikela ukuqhuma) kungenziwa ngokwezifiso ngokuya ngesilinganiso sokugeleza kwegesi, izidingo zokukhuphuka kwezinga lokushisa, usayizi wamapayipi, ingcindezi, ukwakheka kwegesi, njll.

Isicelo somkhiqizo

Izifudumezi zomoya ezisemgqeni wepayipi zisetshenziswa kabanzi kwabaningi izimo zohlelo lokusebenza, njenge:

I-Chemical and Petrochemical: Amagesi enqubo yokushisa (njenge-nitrogen, i-hydrogen, i-argon, i-carbon dioxide, igesi eqhekekayo, igesi esabelayo), ukuvimbela ukufiphala kwegesi, ukushisa kwangaphambili ngaphambi kokukhishwa kwegesi ne-denitrification, njll.

Uwoyela negesi yemvelo: ukushisisa igesi yemvelo (i-antifreeze, i-depressurization kanye ne-anti icing), igesi ehambisanayo, i-flare gas, ukushisisa amapayipi ngemva kokufakwa kwegesi ye-petroleum gasification (LPG), ukuphelelwa amandla kwamanzi kwegesi yemvelo/ukufudumeza kwangaphambi kwemitha, njll.

Ugesi: Ukushisa kwe-boiler air (umoya oyinhloko, umoya wesibili), ukushisisa kabusha kwegesi ye-flue yesistimu ye-desulfurization, njll.

Ukuvikelwa kwemvelo: Ukushisa ngaphambili kwegesi ephumayo ekulashweni kwegesi yemfucuza ye-VOC (i-catalytic combustion, i-RTO/RCO).

Ilabhorethri: Ukulawulwa okunembile kwezinga lokushisa legesi lokuhlola.

Futhi njll....
