Nws ua haujlwm li cas?

Lub phaj kub hloov pauv tuaj yeem siv tshwj xeeb rau kev kho cua sov xws li cua sov thiab txias ntawm cov kua nruab nrab lossis nruab nrab muaj cov khoom ntxhib thiab fiber ntau hauv cov piam thaj, papermaking, metallurgy, ethanol thiab tshuaj industries.

Kev tsim tshwj xeeb ntawm lub tshav kub pauv phaj ua kom zoo dua cov hluav taws xob hloov hluav taws xob thiab kev poob siab dua li lwm yam khoom siv hluav taws xob sib hloov hauv tib yam. Kev khiav dej num ntawm cov kua dej hauv qhov dav dav channel kuj tau ua kom ntseeg tau. Nws paub txog lub hom phiaj ntawm tsis muaj "qhov chaw tuag" thiab tsis muaj qhov tso tawm lossis thaiv ntawm cov lus ntxhib los yog raug tshem tawm.

Cov channel ntawm ib sab yog tsim ntawm cov phaj tiaj tiaj thiab tiaj tus phaj uas welded ua ke nrog stud. Cov channel ntawm sab nraud yog tsim ntawm cov phaj tiaj tiaj nrog qhov sib txawv dav, thiab tsis muaj qhov sib cuag. Ob txoj kev yog tsim rau siab viscous nruab nrab los yog nruab nrab uas muaj coarse hais thiab fiber.

Daim ntawv thov

Alumina, feem ntau yog xuab zeb alumina, yog raw khoom rau alumina electrolysis. Cov txheej txheem ntau lawm ntawm alumina tuaj yeem raug cais raws li Bayer-sintering ua ke. Daim ntawv thov ntawm phaj kub exchanger nyob rau hauv alumina kev lag luam ntse txo erosion thiab blockage, uas nyob rau hauv lem nce tshav kub exchanger efficiency thiab ntau lawm efficiency.

Phaj kub exchangers yog siv raws li PGL txias, agglomeration txias thiab interstage txias.

Lub tshav kub exchanger yog siv nyob rau hauv nruab nrab kub poob Rhiav seem nyob rau hauv lub decomposition thiab grading kev txiav txim ua hauj lwm nyob rau hauv lub zus tau tej cov alumina, uas yog ntsia rau saum los yog hauv qab ntawm decomposition tank thiab siv los txo qhov kub ntawm aluminium hydroxide slurry nyob rau hauv lub decomposition. txheej txheem.
