Kev Sib Tw Engineering hauv Corrosive Heating Environments
Hauv cov txheej txheem kev ua tshuaj lom neeg, tshwj xeeb tshaj yog cov uas muaj cov kua qaub muaj zog, oxidizing cov neeg ua haujlwm, lossis siab -purity media, kev xaiv cov khoom cua sov txuas ntxiv tshaj qhov kev ua haujlwm thermal. Kev tiv thaiv corrosion dhau los ua qhov ntsuas qhov ntsuas uas cuam tshuam ncaj qha rau kev ua haujlwm kev ntseeg siab, kev pheej hmoo kis kab mob, thiab tus nqi ntawm lub neej. Ntawm cov ntaub ntawv muaj, corrosion-resistant quartz hluav taws xob cua sov raj tau tshwm sim los ua ib qho kev daws teeb meem vim lawv cov tshuaj lom neeg tshwj xeeb inertness thiab thermal stability.
Kev tsim cov raj cua kub zoo li no tsis yog ib qho kev hloov khoom siv xwb. Nws sawv cev rau qhov sib npaug ntawm kev tsim vaj tsev sib npaug ntawm kev tswj hwm kev ncaj ncees nyob rau hauv cov tshuaj lom neeg ua phem thaum ua kom muaj kev hloov pauv mus rau cov txheej txheem nruab nrab. Cov kev sib tw yog nyob rau hauv optimizing tsis xws li sheath purity, nto zoo, thiab phab ntsa thickness kom ua tau ob qho tib si durability thiab zog efficiency. Kev nkag siab zoo ntawm cov xwm txheej no muab lub hauv paus rau cov lus qhia tshwj xeeb hauv siab -xav tau kev lag luam ib puag ncig.
Material Inertness thiab cov qauv ruaj khov hauv Corrosive Media
Fused quartz, feem ntau yog tsim los ntawm siab - purity silicon dioxide (SiO₂), ua pov thawj zoo heev rau ntau yam corrosive tshuaj, suav nrog feem ntau cov kua qaub tshwj tsis yog hydrofluoric acid thiab muaj zog alkalis ntawm qhov kub siab. Qhov kev ruaj ntseg ntawm cov tshuaj no ua kom ntseeg tau tias cov quartz sheath tsis hnov mob nrog cov txheej txheem nruab nrab, yog li tshem tawm cov kev pheej hmoo ntawm kev sib kis uas tseem ceeb hauv cov khoom siv hluav taws xob, tshuaj, thiab kev siv tshuaj tshwj xeeb.
Los ntawm kev xav txog kev siv tshuab, corrosion-cov quartz cua sov cov raj muaj kev tiv thaiv lawv cov qauv kev ncaj ncees nyob rau lub sijhawm ua haujlwm ntev. Tsis zoo li cov khoom siv hluav taws xob cua sov, uas tuaj yeem raug kev txom nyem los ntawm pitting corrosion, kev nyuaj siab corrosion cracking, los yog oxide txheej degradation, quartz tseem nyob ruaj khov nyob rau hauv lub sij hawm raug mus rau ib puag ncig hnyav. Cov qauv siv tshuab qhia tau hais tias qhov tsis muaj corrosion- cuam tshuam qhov tsis xws luag yuav txo qis qhov tshwm sim ntawm qhov pib tawg, yog li txhim kho tag nrho kev ntseeg siab ntawm cov cua sov.
Txawm li cas los xij, nws yog ib qho tseem ceeb kom paub tias quartz yog cov khoom siv uas muaj zog tensile tsawg piv rau cov hlau. Nws qhov kev ua tau zoo ntawm kev siv tshuab yog nyob ntawm qhov zoo ntawm qhov chaw thiab qhov tsis muaj micro- tsis xws luag. Nyob rau hauv ib puag ncig corrosive qhov twg txhua yam erosion los yog particle impingement yuav tshwm sim, tuav ib tug du, tsis xws luag -dawb nto ua ib qho tseem ceeb rau khaws cia lub zog.
Thermal Performance thiab Heat Transfer Efficiency
Tus cwj pwm thermal ntawm corrosion-resistant quartz hluav taws xob cua sov raj yog tswj hwm los ntawm ob qho tib si cov khoom thiab cov qauv duab geometric. Quartz muaj cov thermal conductivity tsawg piv rau cov hlau, feem ntau nyob rau hauv thaj tsam ntawm 1.3-1.5 W / m·K ntawm chav tsev kub. Raws li qhov tshwm sim, lub quartz sheath qhia txog qhov ntsuas thermal tsis kam ntawm cov cua sov thiab cov txheej txheem dej.
Raws li Fourier txoj cai, lub tshav kub hloov pauv hloov pauv hloov pauv hloov pauv mus rau thermal tsis kam ntawm cov khoom txheej. Hauv cov ntsiab lus ua tau zoo, qhov no txhais tau hais tias txhua qhov kev nce hauv sheath thickness los yog txo cov thermal conductivity yuav ua rau kom kub hloov mus. Rau corrosion-cov kav dej quartz, kev tswj xyuas qhov zoo ntawm phab ntsa tuab yog qhov tseem ceeb los txo qhov kev tiv thaiv no thaum tseem ua kom muaj kev ua haujlwm ruaj khov.
Tsis tas li ntawd, lub thermal inertia ntawm quartz plays lub luag haujlwm hauv kev ua haujlwm. Thicker lossis denser quartz cov qauv xav tau ntau lub zog kom ncav cuag qhov kub thiab txias, uas tuaj yeem ncua cov txheej txheem pib thiab txo qhov kev siv hluav taws xob tag nrho. Conversely, thinner designs txhim kho tshav kub hloov pauv thiab txo lub sij hawm teb tab sis tej zaum yuav cuam tshuam cov neeg kho tshuab robustness nyob rau hauv hnyav ib puag ncig.
Kev lag luam cov ntaub ntawv los ntawm cov cua kub immersion qhia tau hais tias optimizing quartz sheath geometry tuaj yeem txhim kho thermal efficiency los ntawm 10-20% nyob rau hauv ib puag ncig tswj, tshwj xeeb tshaj yog qhov yuav tsum tau ceev cua sov mus. Qhov no qhia txog qhov tseem ceeb ntawm kev sib koom ua ke ntawm thermal tsom xam rau hauv cov txheej txheem tsim es tsis yog kho corrosion kuj raws li ib qho kev sib cais.
Tsis kam rau Thermal Shock thiab Cyclic Loading
Ib qho ntawm qhov txawv ntawm qhov zoo ntawm quartz yog nws cov thermal shock tsis kam, vim nws qhov qis coefficient ntawm thermal expansion. Cov cuab yeej no tso cai rau quartz cua sov cov raj tuaj yeem tiv taus qhov kub thiab txias hloov pauv yam tsis muaj kev puas tsuaj loj, qhov yuav tsum tau muaj nyob rau hauv cov txheej txheem uas nquag cua sov thiab cua txias.
Nyob rau hauv ib puag ncig corrosive, thermal shock kuj tseem ceeb dua. Cov txheej txheem tshuaj lom neeg feem ntau cuam tshuam nrog kev ua haujlwm tsis tu ncua, hloov cov kua dej, lossis kub kub hloov pauv sai. Quartz lub peev xwm los ua siab ntev rau cov xwm txheej no yam tsis muaj kev tawg ua kom muaj kev ntseeg tau ntawm lub cev thiab txo qis kev saib xyuas zaus.
Txawm li cas los xij, thermal stress tis nyob rau hauv lub quartz sheath yuav tsum tau ua tib zoo tswj. Tsis yog- cov cua kub tsis sib xws, qhov chaw hotspots, lossis txias txias tuaj yeem ua rau muaj kev ntxhov siab sab hauv. Nyob rau tib lub sijhawm, cov kev ntxhov siab no tuaj yeem ua rau microfractures, tshwj xeeb tshaj yog tias ua ke nrog cov khoom siv hluav taws xob lossis cov khoom siv sab nraud. Kev tsim qauv engineering yuav tsum ua kom ntseeg tau tias cov khoom siv hluav taws xob sib txawv thiab cov qauv kev txhawb nqa txaus los txo cov kev pheej hmoo no.
