Lub hauv paus ntsiab lus ntawm Jacketed Reactor

Nyob rau hauv lub realm ntawm chemical engineering thiab industrial cov txheej txheem, lub tsho tsho reactor sawv ua ib lub hauv paus pob zeb khoom. Nws cov qauv tsim thiab kev ua haujlwm yog qhov tseem ceeb rau kev ua tiav cov txiaj ntsig zoo, tswj tau, thiab muaj kev nyab xeeb tshuaj. Kab lus no delves rau hauv lub hauv paus ntsiab lus ntawm lub tsho tsho reactor, tshawb txog nws cov qauv, kev ua haujlwm, thiab ntau yam kev siv hauv kev lag luam uas nws ua lub luag haujlwm tseem ceeb.

 

Lub tsho tsho reactor, tseem hu ua ob-walled reactor, yog ib qho khoom siv zoo nkauj uas muaj cov hlab ntsha sab hauv (core) thiab ib puag ncig lub plhaub (lub tsho). Lub nkoj sab hauv tuav cov tshuaj reactants, thaum lub tsho sab nrauv ncig lub cua sov lossis dej txias. Qhov kev teeb tsa no tso cai rau kev tswj xyuas qhov kub thiab txias ntawm cov reactants, uas yog qhov tseem ceeb rau ntau cov tshuaj tiv thaiv kom ua tau zoo nrog cov txiaj ntsig siab.

 

Jacketed reactor tus tsim yog ob qho tib si tshiab thiab siv tau. Lub reactor nws tus kheej feem ntau yog ua los ntawm cov ntaub ntawv xws li iav, stainless hlau, los yog hlau, nyob ntawm seb cov kev thov tshwj xeeb thiab ib puag ncig (laboratory, pilot plant, etc.). Lub nkoj sab hauv, uas tuav cov reactants, yog nyob ib puag ncig los ntawm lub tsho sab nrauv uas nthuav tawm cov kua dej hloov hluav taws xob, xws li dej lossis roj.

 

Lub tsho ua haujlwm rau ob lub hom phiaj: nws tswj qhov kub thiab txias ntawm cov tshuaj tiv thaiv hauv cov tub ntxhais cov hlab ntsha thiab muab cov txheej txheem thib ob ntawm rwb thaiv tsev. Qhov rwb thaiv tsev no yuav pab tswj kom muaj qhov kub thiab txias nyob rau hauv lub reactor, tiv thaiv kom tsis txhob kub los yog nce. Qhov tseem ceeb ntawm kev tswj xyuas qhov ntsuas kub tsis tu ncua tsis tuaj yeem tshaj tawm, vim tias muaj ntau yam tshuaj lom neeg cov tshuaj tiv thaiv yuav tsum muaj qhov kub thiab txias kom ua tau zoo.
