Lub evaporator yog ib qho khoom siv dav siv hauv kev lag luam thiab kev ua neej txhua hnub. Nws lub luag haujlwm tseem ceeb yog kom ua tiav cov cua sov hloov pauv thiab cov khoom sib cais los ntawm cov txheej txheem hloov pauv ntawm cov kua mus rau roj.
Tshwj xeeb, tus evaporator evaporates cov kuab tshuaj (xws li dej) hauv cov kua rau hauv lub xeev gaseous los ntawm cua sov los yog txo lub siab, thaum lub kua (xws li ntsev, organic teeb meem, thiab lwm yam) yog concentrated los yog crystallized tawm, yog li ua tiav kev sib cais, purification, los yog txo ntim. Cov txheej txheem no plays lub luag hauj lwm irreplaceable nyob rau hauv tshuaj, tshuaj, khoom noj khoom haus, kev kho dej khib nyiab, thiab seawater desalination industries.
Lub hauv paus ntawm lub evaporator yog cov txheej txheem hloov hluav taws xob. Ua ib qho kev sib txuam ntau-effect evaporator ua piv txwv, nws siv ntau lub evaporation units txuas nrog hauv cov koob, siv cov chav thib ob uas tsim los ntawm cov nyhuv dhau los ua cov cua sov rau cov nyhuv tom ntej, ua tiav kev siv hluav taws xob cascade, yog li txo qis zog noj. Piv txwv li, kev siv lub zog ntawm triple -effect evaporator tsuas yog kwv yees li 1/3 ntawm ib zaug xwb -effect evaporator. Tsis tas li ntawd, cov evaporators membrane ua tiav cov kuab tshuaj thiab cov kua dej sib cais los ntawm kev xaiv permeation ntawm microporous daim nyias nyias, uas muaj kev siv hluav taws xob tsawg thiab kev ua haujlwm kub, ua rau lawv tshwj xeeb tshaj yog tsim nyog rau cov ntsiab lus ntawm tshav kub- cov khoom rhiab heev.
