Ua ntej, peb tuaj yeem pom nws ' sa txhuam txhuam. Nws ua haujlwm li cas?
Cov pa paug tau nkag mus rau hauv tus pej thuam, qee qhov roj pa nkag mus ua kua thiab tseem nyob hauv qab pej thuam. Kho qhov kub ntawm lub reboiler kom cov kua evaporates nce, thiab tom qab ntawd kho lub condenser kom cov kua ntws rov mus rau lub tais, tsim kom muaj qhov sib npaug. Los ntawm kev ntim txheej, ntawm txheej txheej ntim, roj-kua theem nyob ze rau cov huab hwm coj hloov mus. Cov roj yuav dhau ntawm lub dab , thiab cais cov ya raws, tom qab ntawd cov roj huv huv mus rau ntauwd.

Yuav ua li cas xaiv cov ntawv random thiab cov pob teeb tsa ?
Tus muab tub lim khoom tau muab faib ua peb pawg: ceramic, hlau thiab yas.
(1) C eramic packing muaj zoo corrosion tsis kam thiab kub tsis kam, ceramic ntim yog pheej yig, muaj qhov zoo ntawm qhov chaw ntub dej, khoom tawg, tsis huv yog nws qhov tsis zoo tshaj plaws. Nws yog dav siv hauv kev nqus roj, ntxuav roj thiab kua ua kua.
(2) M etal packing tuaj yeem ua los ntawm ntau cov ntaub ntawv, feem ntau xav txog qhov teeb meem corrosion thaum xaiv. Cov hlau ntim tuaj yeem ua rau nyias-phab ntsa qauv, nws cov flux yog loj, cov roj tsis kam yog qhov me me, thiab muaj qhov cuam tshuam loj, tuaj yeem siv rau hauv qhov kub thiab txias, siab ntsig, siab zog, feem ntau siv.
(3) P kawg ntim cov khoom ntawm cov yas muab tub lim feem ntau suav nrog polypropylene (PP), polyethylene (PE) thiab polyvinyl chloride (PVC). Cov yas ntim khoom muaj cov tshuaj tiv thaiv zoo corrosion thiab tuaj yeem tiv taus qhov corrosion ntawm cov inorganic acid, alkali thiab organic solvent. Nws muaj qhov kub thiab txias tsis zoo thiab tuaj yeem siv qis dua 100 ° C rau lub sijhawm ntev. Cov yas ntim khoom yog lub teeb, pheej yig, muaj cov tawv zoo, muaj kev cuam tshuam, tsis yooj yim tawg, tuaj yeem ua rau hauv cov qauv nyias-ntsa. Nws yog dav siv hauv kev nqus, desorption, tshem tawm, hmoov av tshem tawm thiab lwm yam khoom siv.
