Tshuaj ntxuav txoj kev nyob rau hauv thermal roj rhaub system
Tso lus
Cov tshuaj ntxuav cov txheej txheem rau lub thermal roj cua sov system yog raws li nram no: alkali ntxuav thiab kua qaub ntxuav ob-kauj ruam txheej txheem: tawm ntawm thermal roj → chav tshuab ntawm stagnant roj → alkaline ntxuav tus neeg saib xyuas → dej yaug → kua qaub ntxuav → passivation → tiav. Lub hauv paus ntsiab lus: Alkaline dej-raws li tus neeg saib xyuas muaj txiaj ntsig zoo rau kev kho mob nruab nrab ntawm cov pa roj carbon deposits hauv cov roj, tab sis tom qab kev kho mob, tseem muaj qhov ntom ntom graphitized high-temperature carbon deposit txheej seem ntawm phab ntsa sab hauv ntawm daim ntawv xeem. Yog li ntawd, ntxiv cov kua qaub ntxuav yog tsim nyog los tshem tawm cov seem carbon txheej kom tsis txhob muaj kev cuam tshuam qhov zoo thiab kub hloov pauv ntawm cov roj hloov hluav taws xob.
② Kev tshem tawm cov txheej txheem: tshem tawm cov roj hloov hluav taws xob → chav tshuab ntawm cov roj uas tsis muaj zog → ntxuav nrog cov kuab tshuaj ntxuav cov organic (organic hnyav ntxiv rau SAA ntxiv rau ntxiv) → passivation.
③ Composite tu tus neeg saib xyuas kev tu txheej txheem: tso tawm cov roj hloov hluav taws xob → chav tshuab tawm cov roj tsis tu ncua → ntxuav cov kua dej huv.
④ Organic additive tu txheej txheem: Tsuas yog ntxiv cov khoom ntxiv rau cov roj hloov hluav taws xob ua kom cov pa roj carbon deposit tev tawm thiab tom qab ntawd tshem tawm thiab lim cov roj seem.
Lub hauv paus ntsiab lus: Qhov kev sib ntxiv no siv lub hauv paus ntsiab lus ntawm kev solubility zoo sib xws los ntxuav cov coke nplai lossis degrade tar nplai kom tiv thaiv cov roj thermal los ntawm kev puas tsuaj. Txoj kev no yog siv los ntxuav yam tsis tau nres tsheb. Cov tshuaj ntxiv tuaj yeem yaj hauv cov roj hloov hluav taws xob ntawm qhov kub siab tshaj 260 degree yam tsis muaj kev cuam tshuam rau nws lub cev, thiab kev kam rau siab tsis tuaj yeem tshaj 5 feem pua ntawm cov roj hloov hluav taws xob.
Tus neeg saib xyuas rau cov roj cua kub cua sov feem ntau yog ua ke ntawm peb yam tseem ceeb: alkali, organic solvent, thiab surfactant (SAA), thiab lwm yam additives xws li complexing agents, oxidants, corrosion inhibitors, adsorbents, thiab anti deposition agents. Los ntawm cua sov, tshuab ntxhua khaub ncaws, thiab lwm yam kev ua, lub hom phiaj kawg yog tshem tawm coke thiab nplai hauv qhov system. Lub luag haujlwm ntawm cov tshuaj ntxuav hauv coke tu yog ua tiav los ntawm kev solubilization, ntub dej, adsorption, emulsification, thiab dispersion ntawm surfactants.
