Dab tsi yog hom evaporators thiab lawv lub luag haujlwm yog dab tsi?

Evaporator yog ib qho khoom siv hluav taws xob hloov hluav taws xob, nws cov hom muaj xws li: evaporator ncaj qha, evaporator tsis ncaj, extractor thiab lwm yam. Ntau hom evaporators kuj muaj lawv tus kheej cov yam ntxwv hauv kev siv, thiab tuaj yeem ua tau raws li qhov xav tau ntau lawm.

Cov evaporator ncaj qha yog kom vaporize cov khoom kho ncaj qha rau ntawm qhov chaw cua sov, uas tuaj yeem siv tau cov cua sov kom zoo. Hauv cov ntawv thov kev lag luam, nws feem ntau yog siv rau hauv kev tsim cov khoom ua liaj ua teb thiab cov khoom siv sab nrauv kom qhuav thiab crushing, nrog rau kev ua kom zoo syrup. Indirect evaporators hloov cov cua sov mus rau cov khoom kho los ntawm conduction rau evaporation. Txij li thaum cov kev kho mob tsis tuaj rau hauv kev sib cuag nrog cov cua sov saum npoo, kev sib txuas thiab kev sib kis ntawm qee qhov kev kho mob tuaj yeem zam tau. Extractors feem ntau yog siv nyob rau hauv lub teb ntawm biochemistry, uas muaj peev xwm cais cov sib txawv Cheebtsam nyob rau hauv lub sib tov.

Lub luag haujlwm ntawm lub evaporator tsis yog tsuas yog hloov cov cua sov xwb, tab sis kuj tuaj yeem ua tiav ntau lwm yam haujlwm, xws li:

1. Concentration: evaporates cov dej nyob rau hauv cov tshuaj, ua rau nws me me nyob rau hauv ntim thiab siab dua nyob rau hauv concentration kom ua tau raws li lub hom phiaj ntawm kev txuag cia thiab kev thauj mus los.

2. Rectification: Chav los ntawm kev daws teeb meem, cov khoom tsis sib haum xeeb raug tshem tawm, thiab tom qab ntawd txias rau hauv cov kua los ntawm lub condenser, thiaj li ua tiav cov khoom sib cais.

3. Kev ziab: evaporates cov dej hauv cov khoom lossis kua kom ua tiav lub hom phiaj ntawm kev ziab.

Evaporators tau siv dav hauv ntau lub lag luam, xws li tshuaj lom neeg, khoom noj khoom haus, tshuaj, metallurgy, kev lag luam teeb thiab lwm yam. Los ntawm ntau hom evaporator thiab kev ua haujlwm sib xws, ntau yam teeb meem thermodynamic tuaj yeem daws tau, kev tsim khoom thiab cov khoom zoo tuaj yeem txhim kho, thiab kev txhim kho kev lag luam tuaj yeem txhawb nqa. Yog li ntawd, evaporators yog ib feem tseem ceeb ntawm kev lag luam niaj hnub.
