Raws li cov khoom tseem ceeb ntawm kev ua kua conveying tshuab, tshuaj chemical ua si ib lub luag haujlwm irreplacable lub luag haujlwm hauv kev lag luam tshiab chem. Lawv txoj kev tshawb fawb muaj txuj ci tsis yog tsuas yog kev tswj cov txheej txheem hloov chaw, tab sis kuj tseem muaj kev sib xyaw ua ke tsim kho tshiab, thiab ua kom muaj kev txhim kho kev txhim kho kom muaj kev loj hlob. Los ntawm microscopic molecular rau macroscopic muaj cov txheej txheem, kev tshawb xyuas tus nqi tshuaj chemical permeated permeates txhua qhov kev xav thiab kev coj ua.
I. Tshuaj lom neeg twj yog cov txheej txheem dynamic ntawm cov tshuaj tiv thaiv engineering
Hauv kev tsim cov tshuaj lom neeg, cov txheej txheem xws li cov khoom siv raw sib xyaw, cov khoom siv hluav taws xob, thiab cov khoom sib cais txhua qhov kev cia siab rau cov kev ntsuas ntws. Tshuaj lom neeg cov twj tshuaj lom neeg ua kom ntseeg tau tias tus nqi hloov khoom siv tsis pub dhau cov tshuaj tiv thaiv kev siv tshuaj tua kab thiab tswj hwm ruaj khov. Piv txwv li, hauv high- qhov kev tawm tsam siab, ntau} {3} {{3} {{30er molecules ntawm nanometer nplai. Hauv micrortector thev naus laus zis, microos cov twj faib kua rau hauv picoliter hauv picoliter, ua kom muaj kev tswj hwm ntawm cov kev tiv thaiv ntawm milliseconds. Qhov no ua kom tswj cov kua dej tsis zoo yog qhov tseem ceeb ntawm kev tsim kho cov engineering ntawm tsis {}} kev sib npaug}} kev sib npaug ntawm cov txheej txheem thermodynamic.
Ii. Kev Koom Tes Kev Koom Tes Ua Lag Luam hauv cov khoom siv science thiab kua fynamics
Tshuaj lom neeg cov kev tshawb fawb thiab kev txhim kho txuas ntxiv mus rau cov kev ua tau zoo hauv cov khoom ua haujlwm nyob rau hauv kev ua haujlwm dhau los. Rau cov khoom siv hluav taws xob heev (xws li muaj cov roj acid thiab hydrofluoric acid), muaj kev ua kom zoo nkauj los ntawm cov khoom siv tshuaj txhuam dej (xws li cov kua hluav taws xob. Cov khoom cua (CFD) sim. Qhov tsim muaj ntawm cov nqus mis sib nqus thaum lub xyoo pua 20th muaj tswv yim hais txog qhov teeb meem ntawm cov ntxaij to. Los ntawm kev xa lub zog los ntawm kev sib cav sib ceg tas li Qhov kev sib tsoo no ncaj qha pab rau kev paub tab ntawm ultra-huv si conventing thev naus laus zis rau semiconductor hluav taws xob tshuaj.
III. Zog hloov siab hloov siab thiab cov pivot ntawm cov txheej txheem kev lag luam
In process industries such as petroleum refining and coal chemical processing, pump systems consume approximately 25%-30% of a plant's total energy consumption. Kev tsim qauv ntawm cov zog heev thiab lub zog - Kev ua kom txuag tau cov kua dej tsis zoo, thiab muaj tswv yim tswj kev tswj hwm. Piv txwv li, impellers tsim siv ternary flow txoj kev xav tau nce centrifugal twj siv tshuab ntxiv txo cov nqi ntawm kev ua haujlwm los ntawm 15% {{}} 20%. Ntawm cov tswv yim tseem ceeb tshaj plaws, hauv kev lag luam hydrogen ntau zog, Kev txhim kho ntawm cov khoom siv ntawm ntug yog ncaj qha rau kev tsim kho cov khoom siv hluav taws xob huv thiab kev thauj mus los.
IV. Cov thev naus laus zis rau kev txhim kho kom ruaj khov
Niaj hnub chemical tshuaj lom quav tshuaj yog kev sib xyaw ua ke rau hauv cov tshuab ntsuab. Los ntawm kev tsim cov xau -} Dawb sealing qauv, thiab kev khiav tawm ntawm cov khoom siv hluav taws xob (vocs) Nyob rau hauv cov carbon ntes teb, corrosion {{{{ove} {Resistant Slurry twj pab tau zoo kev thauj khoom ntawm high selgentrrtrtrtrtrtrtrtrtrtrtrtrtrtrtrtrtrtrtrtrtration amine nqus; Nyob rau hauv kev kho dej lwg, corrosion - tiv thaiv cov twj sib nqus tsav kom ua kom muaj kev nyab xeeb ntawm cov hlau hnyav {}} muaj sludge. Cov thev naus laus zis thev naus laus zis ua rau cov kev siv ntawm lub hauv paus ntsiab lus ntawm "Atom kev lag luam" hauv kev ua lag luam engineering. Txhua 1% nce hauv kev nqus dej ua haujlwm feem ntau txhais ua kom txo qis ntawm kaum txhiab tus tons ntawm cov pa roj carbon emissions. Los ntawm cov cim hauv mendeleev lub rooj ntu sij hawm rau cov steel jargles, tshuaj lom neeg tau nkag siab txog cov ntaub ntawv hloov pauv thiab nws cov ntawv thov muaj tswv yim. Lawv qhov tseem ceeb ntawm kev tshawb fawb tau hloov mus ntev ntawm cov khoom siv uas yooj yim ntawm cov kua ntawm lub ntsej muag thiab kev tsav tsheb ntawm kev vam meej ntawm kev vam meej ntawm macroscopic qib.
Nrog rau kev nkag mus ntawm cov thev naus laus zis xws li cov ntxig tshuaj ntse, cov twj tshuaj yeeb muaj zog, cov khoom siv thev naus laus zis ntau dua.
