Dab tsi yog cov khoom siv hluav taws xob siv hauv kev lag luam chemical?
A: Cov khoom siv hluav taws xob siv hluav taws xob siv hauv kev lag luam tshuaj yog cov khoom siv hluav taws xob tshwj xeeb uas tsim los tiv thaiv kev ua haujlwm hnyav ntawm cov khoom siv tshuaj lom neeg (xws li kub kub, kub siab, muaj zog corrosion, thiab ntau- xov xwm sib xyaw). Lawv lub luag haujlwm tseem ceeb yog los pauv cov cua sov los ntawm txoj hauv kev xws li kev sib cuag tsis ncaj, sib xyaw, lossis cov txheej txheem rov ua dua tshiab.Nws ua kom cov cua sov hloov ntawm ob lossis ntau dua cov kua dej ntawm qhov sib txawv, yog li ua tau raws li qhov xav tau ntawm cov cua sov, cua txias, thiab khib nyiab rov qab los ntawm cov txheej txheem tshuaj. Kev nyab xeeb thiab cov khoom zoo.Cov qauv qauv muaj xws li lub plhaub thiab lub raj hom, phaj hom, kauv qhov txhab hom, thiab lwm yam. Ntawm lawv, lub plhaub thiab lub raj cua kub exchangers tau dhau los ua ib qho ntawm cov khoom siv hluav taws xob sib pauv hauv kev lag luam tshuaj lom neeg vim lawv cov qauv muaj zog thiab dav adaptability.
Dab tsi yog cov khoom tseem ceeb ntawm cov khoom siv hluav taws xob siv hauv kev lag luam tshuaj?
A: Cov yam ntxwv ntawm cov khoom siv hluav taws xob siv hauv kev lag luam chemical yog tsim los ntawm qhov nyuaj thiab hnyav ntawm cov tshuaj ua haujlwm, thiab cov yam ntxwv tseem ceeb suav nrog cov hauv qab no:
1. High-kev ua haujlwm kub hloov pauv tau zoo: Los ntawm kev ua kom zoo ntawm cov qauv tsim, kev hloov pauv hluav taws xob tuaj yeem txhim kho. Piv txwv li, nyob rau hauv lub plhaub thiab lub raj cua kub exchangers, baffles yog siv los coj cov kua los tsim turbulence, uas yuav ua rau kom turbulence siv los ntawm 40% thiab tag nrho cov tshav kub hloov coefficient los ntawm 20% -30%. qhov counter-tam sim no tsim muaj peev xwm tshaj 95%.
2. Muaj zog yoog raws ntau yam kev ua haujlwm: Nws muaj qhov kub thiab txias adaptability, nrog rau qhov kub thiab txias ntawm -196℃txog 1800℃thiab lub siab ua haujlwm siab tshaj 40MPa, thiab tuaj yeem hloov mus rau qhov kev ua haujlwm hnyav xws li supercritical thiab kub sib txawv. Meanwhile, ntau yam qauv tsim tuaj yeem hloov kho rau cov kev xav tau sib txawv. Piv txwv li, hom ntab taub hau thiab hom U-tube tuaj yeem daws cov teeb meem thermal expansion nyob rau hauv qhov sib txawv ntawm qhov kub thiab txias thiab zam cov khoom deformation thiab to.
Dab tsi yog cov khoom tseem ceeb ntawm cov khoom siv hluav taws xob siv hauv kev lag luam tshuaj?
Nws cov haujlwm hloov pauv ntawm kev tswj qhov kub thiab txias thiab kev siv hluav taws xob zoo thoob plaws tag nrho cov txheej txheem tshuaj lom neeg, thiab nws cov tub ntxhais muaj xws li;
1. Precise tswj ntawm txheej txheem kub
Raws li cov exothermic lossis endothermic cov yam ntxwv ntawm cov tshuaj tiv thaiv, cov cua sov raug tshem tawm lossis rov ua dua hauv lub sijhawm tiag tiag kom ntseeg tau tias qhov kev ua tau zoo ntawm cov tshuaj tiv thaiv.Piv txwv li, hauv cov tshuaj tiv thaiv exothermic xws li styrene-butadiene roj hmab polymerization, qhov kub tuaj yeem tswj tau ntawm 50-60℃; Hauv kev tsim tshuaj tua kab mob, kev tswj qhov kub thiab txias ntawm ± 0.5℃tuaj yeem ua tiav los xyuas kom meej cov khoom zoo thiab sib xws.
