Txheej Txheem Flow Ntawm Aluminium Hydroxide
Feb 04, 2022
Aluminium hydroxide roasting feem ntau yog nqa tawm nyob rau hauv ib lub teb kiln los yog ib tug fluidized rauv.
(1) Thaum roasting nyob rau hauv ib tug rotary kiln, pub cov ntxhua ntub dej txhuas hydroxide rau hauv ib kawg ntawm lub kiln, tshuaj tsuag cov roj hnyav lossis roj los ntawm lwm qhov kawg ntawm lub qhov cub, thiab ua kom tiav cov tshuaj tiv thaiv xws li ziab, tshem tawm cov dej siv lead ua thiab siv lead ua. transformation nyob rau hauv lub kiln. Txheej txheem, tso tawm, thiab tau txais alumina tom qab txias.
(2) Thaum roasting nyob rau hauv ib tug fluidized rauv, cov ntub dej aluminium hydroxide yog thawj zaug pub rau hauv lub tshuab ziab khaub ncaws, thiab tom qab ntawd xa mus rau lub tshuab hluav taws xob, cov roj txhaj tshuaj kom ci rau hauv alumina, thiab tom qab ntawd dhau los ntawm qhov chaw nyob tank, ntau theem cua daj cua dub. Thaum tshav kub kub exchanger ntaus ntawv thiab fluidized txaj. Lub tshuab ua kom txias txias, uas yog cov khoom kawg. Fluidized rauv roasting system tuaj yeem siv tag nrho cov cua sov tso tawm los ntawm combustion tso pa roj thiab cov khoom txias kom preheat cov khoom txias tuaj thiab cov roj thiab cua xav tau rau combustion. Cov ntaub ntawv hauv qhov system yog tag nrho hauv lub xeev fluidized. Kev ua haujlwm siab thermal thiab kev siv hluav taws xob tsawg, tsuas yog 60 feem pua rau 70 feem pua ntawm cov khoom siv hluav taws xob.
Lub combustion tso pa roj ntawm ob txheej txheem yog tawm mus rau hauv cov huab cua tom qab raug purified los ntawm electrostatic precipitator.
