Hauv kev tsim thiab kev ua haujlwm ntawm cov evaporators, cov khoom siv lub cev thiab tshuaj lom neeg ntawm cov ntaub ntawv yog qhov tseem ceeb hauv kev txiav txim siab cov txheej txheem ntws, cov khoom siv kho kom zoo, thiab kev ua haujlwm ruaj khov. Cov khoom ntawm cov khoom muaj xws li ntau yam - cov yam ntxwv xws li viscosity, boiling point, heat rhiab heev, corrosivity, solids content, and deg nro. Cov cwj pwm no cuam tshuam ncaj qha rau kev hloov pauv hluav taws xob, tus nqi evaporation, thiab cov khoom lag luam zoo, thiab tseem txiav txim siab qhov hloov pauv ntawm hom evaporator thiab cov laj thawj rau kev teeb tsa kev ua haujlwm.
Viscosity yog ib qho ntawm cov kev xav tseem ceeb. High- cov ntaub ntawv viscosity muaj cov dej tsis zoo thiab yooj yim tsim cov khaubncaws sab nraud povtseg ntawm lub tshav kub hloov mus rau qhov chaw, ua rau muaj kev tiv thaiv thermal thiab overheating hauv zos. Txhawm rau hais txog qhov no, cov evaporators raug yuam siv feem ntau, siv cov khoom siv hluav taws xob sab nraud kom nce tus nqi ntws, cuam tshuam cov npoo ciam teb, thiab tswj kom muaj kev sib pauv cua sov. Rau cov dej tsis muaj viscosity tsawg, cov zaj duab xis ntog lossis nce cov evaporators tuaj yeem ua tiav cov evaporation zoo los ntawm cov khoom siv hluav taws xob los yog lub zog nqa, nrog cov qauv yooj yim.
Boiling point thiab boiling ntau cuam tshuam rau evaporation tej yam kev mob thiab lub zog noj tswj. Cov ntaub ntawv uas muaj cov ntsiab lus kub kub yuav tsum muaj cua sov siab dua lossis qis dua kev ua haujlwm kom txo qhov kub qhov sib txawv uas xav tau rau theem hloov. Qhov no yuav tsum tau evaporators nrog zoo siab tsis kam thiab sealing kev ua tau zoo. Kev sib xyaw nrog cov boiling ntau yam yuav tsum tau segmented evaporation los yog multi-effect evaporation kom rho tawm cov Cheebtsam sib txawv kauj ruam-los ntawm- kauj ruam, zam lub decomposition ntawm sib sib zog nqus Cheebtsam los yog coking ntawm hnyav Cheebtsam tshwm sim los ntawm ib tug siab -kub kev kho mob.
Thermosensitivity dictates nruj tswj nyob rau sab sauv kub txwv thiab cua sov lub sij hawm. Khoom noj khoom haus, tshuaj, thiab ib co tshuaj intermediates yog nquag mus deterioration ntawm kub kub; Yog li ntawd, cov evaporators nrog lub sij hawm nyob luv luv thiab tsis tshua muaj kub hloov pauv kub sib txawv, xws li cov khoom siv khib nyiab los yog phaj evaporators, raug pom zoo, ntxiv los ntawm lub tshuab nqus tsev ib puag ncig kom txo qhov kub kub.
Corrosivity thiab solids cov ntsiab lus cuam tshuam rau kev xaiv cov khoom thiab tiv thaiv- ntsuas clogging. Cov khoom siv acidic lossis alkaline yuav tsum siv cov khoom siv corrosion-resistant alloys lossis deg coatings. Kev ncua nrog cov ntsiab lus siab siab yuav tsum tau yooj yim ntxuav cov qauv thiab hnav- tiv thaiv tsim los tiv thaiv crystal lossis particle deposition uas tuaj yeem txhaws cov kab ntws. Nto nro cuam tshuam qhov sib kis thiab sib xws ntawm cov yeeb yaj kiab ua kua, uas yog qhov tseem ceeb tshwj xeeb rau cov evaporators ntog, yuav tsum tau ua kom zoo dua ntawm tus xa khoom kom ua tiav cov dej ntub dej.
Hauv cov ntsiab lus, kev nkag siab zoo ntawm cov khoom siv thiab cov kev daws teeb meem hauv cov txheej txheem tsim yog qhov tseem ceeb rau kev txhim kho kev ua tau zoo thiab kev ntseeg siab ntawm evaporators. Tsuas yog los ntawm kev ua tiav qhov kev sib tw ntawm cov khoom siv thiab cov cuab yeej ua tau zoo tuaj yeem ruaj khov evaporation tau thiab cov khoom zoo heev tau txais nyob rau hauv kev ua haujlwm nyuaj.
