Yuav txawv tshuaj tiv thaiv tshwm sim nyob rau hauv cov reactors ua los ntawm cov khoom sib txawv ntawm qhov kub, siab, thiab chemistry

Qhov cuam tshuam ntawm cov khoom siv reactor ntawm cov tshuaj tiv thaiv tshuaj lom neeg feem ntau tshwm sim hauv cov hauv qab no:

1. Cov tshuaj tiv thaiv ntawm cov tshuaj tiv thaiv nruab nrab thiab cov tshuaj tiv thaiv cov hlab ntsha: Qhov sib txawv ntawm cov khoom sib txawv ntawm cov khoom sib txawv ntawm cov hlab ntsha ntawm cov tshuaj tiv thaiv yuav cuam tshuam ncaj qha rau cov tshuaj tiv thaiv thaum lub sij hawm cov txheej txheem tshuaj tiv thaiv. Cov tshuaj tiv thaiv nruab nrab (reactants, catalysts, cov kuab tshuaj, thiab lwm yam) tuaj yeem raug tshuaj lom neeg nrog cov khoom siv reactor, uas yuav ua rau muaj kev puas tsuaj rau lub reactor lossis muaj kev cuam tshuam loj rau cov khoom siv tshuaj tiv thaiv.

2. Oxidation-txo cov khoom: Muaj qhov sib txawv tseem ceeb hauv oxidation-txo cov khoom ntawm cov hlab ntsha hlau thiab cov iav tshuaj tiv thaiv cov hlab ntsha. Piv txwv li, cov tshuaj tiv thaiv acid-base yooj yim tuaj yeem ua rau xeb hauv cov hlab ntsha hlau, tab sis cov iav tshuaj tiv thaiv cov hlab ntsha tuaj yeem zam cov teeb meem zoo li no. Yog li ntawd, thaum cov tshuaj tiv thaiv kab mob tau yooj yim oxidizable thiab txo cov tshuaj tam sim no, iav reactor feem ntau yog xaiv rau kev kho cov tshuaj tiv thaiv.

3. Corrosion kuj: Hauv kev tsim tshuaj lom neeg, cov tshuaj corrosive xws li cov kua qaub muaj zog, muaj zog alkalis, thiab oxidants feem ntau koom nrog. Yog li ntawd, cov khoom ntawm lubtsho reactoryuav tsum tau xaiv raws li cov ntaub ntawv corrosion-resistant, xws li stainless hlau, fiberglass, thiab lwm yam. Yog hais tias cov corrosion ua hauj lwm ntawm cov khoom yog tsis zoo, nws yog ib qho yooj yim rau cov khoom yuav corroded, yaj, los yog tsim roj thaum lub sij hawm cov tshuaj tiv thaiv txheej txheem, yog li ntawd. cuam ​​tshuam rau kev nce qib ntawm cov tshuaj tiv thaiv thiab purity ntawm cov khoom.

4. Mechanical zog thiab stability: Cov khoom sib txawv ntawm cov hlab ntsha muaj zog muaj zog sib txawv thiab ruaj khov. Piv txwv li, qee cov ntaub ntawv hlau tuaj yeem deform lossis tawg nyob rau hauv qhov kub thiab txias, uas tuaj yeem cuam tshuam qhov ruaj khov ntawm cov tshuaj tiv thaiv.

5. Nqi thiab muaj: Tus nqi thiab muaj cov hlab ntsha ntawm cov khoom sib txawv kuj txawv. Qee cov ntaub ntawv tsis tshua muaj lossis tshwj xeeb yuav kim thiab nyuaj kom tau txais, thaum lwm yam khoom siv yuav pheej yig dua thiab yooj yim mus yuav.

Hauv cov ntsiab lus, kev cuam tshuam ntawm cov khoom siv reactor ntawm cov tshuaj tiv thaiv yog feem ntau cuam tshuam txog tus nqi, kev xaiv, kev ruaj ntseg, khoom zoo, nqi, thiab muaj cov tshuaj tiv thaiv. Yog li ntawd, thaum xaiv cov khoom ntawm cov tshuaj tiv thaiv hlab ntsha, nws yog ib qho tsim nyog yuav tsum tau ua tib zoo xav txog cov tshuaj tiv thaiv tshwj xeeb thiab cov khoom tsim nyog, thiab xaiv cov khoom siv tshuaj tiv thaiv kom tsim nyog los xyuas kom meej cov tshuaj tiv thaiv zoo tshaj plaws.

Tib qhov kub, siab, thiab tshuaj tiv thaiv yuav ua rau muaj kev sib txawv hauvcov hlab ntshantawm cov khoom sib txawv. Qhov no feem ntau yog vim cov hlab ntsha ntawm cov khoom sib txawv muaj qhov sib txawv ntawm lub cev thiab tshuaj lom neeg, uas tuaj yeem cuam tshuam tus nqi thiab cov txiaj ntsig ntawm cov tshuaj tiv thaiv. Piv txwv li, stainless hlau reactor thiab iav reactor yog ob yam khoom siv reactor. Stainless hlau cov tshuaj tiv thaiv cov hlab ntsha muaj kev tiv thaiv corrosion zoo heev thiab kev ua haujlwm kub, ua rau lawv haum rau feem ntau cov tshuaj tiv thaiv. Cov iav tshuaj tiv thaiv cov hlab ntsha, ntawm qhov tod tes, muaj pob tshab thiab yooj yim rau kev soj ntsuam cov txheej txheem tshuaj tiv thaiv, tab sis lawv cov kev tiv thaiv corrosion thiab kub ua haujlwm tsis zoo. Yog li ntawd, nyob rau hauv tib qhov kub thiab txias, siab, thiab tshuaj tiv thaiv kab mob, cov tshuaj tiv thaiv tus nqi thiab ua rau stainless hlau reactors thiab iav reactors yuav txawv. Tsis tas li ntawd, cov tshuaj tiv thaiv cov hlab ntsha ua los ntawm cov khoom sib txawv tuaj yeem muaj qhov sib txawv ntawm lub cev xws li kev hloov hluav taws xob ua haujlwm, coefficient ntawm thermal expansion, deg roughness, thiab lwm yam, uas tuaj yeem cuam tshuam cov txheej txheem ntawm cov tshuaj tiv thaiv. Lwm qhov laj thawj yog tias cov txiaj ntsig ntawm cov tshuaj tiv thaiv kuj tseem cuam tshuam los ntawm ntau lwm yam, nrog rau kev ua kom huv ntawm cov reactants, hom thiab concentration ntawm catalysts, lub sij hawm tshuaj tiv thaiv, stirring ceev, thiab lwm yam. Cov khoom sib txawv ntawm cov hlab ntsha tuaj yeem muaj qhov sib txawv ntawm cov tshuaj tiv thaiv.

Yog li ntawd, thaum xaiv cov khoom ntawm cov tshuaj tiv thaiv hlab ntsha, nws yog ib qho tsim nyog yuav tsum tau ua tib zoo xav txog cov tshuaj tiv thaiv tshwj xeeb thiab cov khoom tsim nyog, thiab xaiv cov khoom siv hluav taws xob tsim nyog los xyuas kom meej qhov ua tau zoo thiab kev nyab xeeb ntawm cov txheej txheem tsim khoom.
