3. Thaum pH ntawm cov tshuaj tiv thaiv mus txog ib qho nqi, nres cov roj ntws, txias cov tshuaj tiv thaiv rau qhov kub thiab txias, thiab tso cai rau sodium hydrosulfide crystallize.

4. Muab cov khoom siv crystallized tso rau hauv lub centrifuge rau kev sib cais centrifugal kom tau txais cov khoom siv sodium hydrosulfide.

5. Muab cov khoom siv sodium hydrosulfide tau los ntawm kev sib cais centrifugal rau hauv cov khoom siv ziab kom qhuav kom tau txais cov khoom siv sodium hydrosulfide zaum kawg.

V. Khoom siv

Cov cuab yeej tsim nyog rau kev tsim cov sodium hydrosulfide suav nrog lub tank dissolution, cov tshuaj tiv thaiv hluav taws xob, lub tank crystallization, centrifuge, thiab cov khoom siv ziab. Cov cuab yeej no yuav tsum ua raws li cov qauv tsim khoom thiab cov kev cai nyab xeeb, thiab lawv yuav tsum tau tswj xyuas thiab tshuaj xyuas kom zoo thiab ua haujlwm zoo.

VI. Kev Tswj Xyuas Zoo

Txhawm rau kom ntseeg tau tias cov khoom siv sodium hydrosulfide zoo, kev tswj xyuas nruj yuav tsum tau ua. Qhov no suav nrog cov hauv qab no:

1. Raw Material Control: Xyuas kom meej tias qhov zoo ntawm sodium hydroxide thiab hydrogen sulfide gas ua tau raws li cov qauv tsim nyog.

2. Reaction Control: Tswj cov roj ntws, qhov kub thiab txias, thiab lub sijhawm kom ntseeg tau tias qhov zoo thiab cov txiaj ntsig ntawm sodium hydrosulfide tsim.

3. Kev Ntsuas Cov Khoom: Ua qhov kev ntsuas zoo ntawm cov khoom tsim sodium hydrosulfide, suav nrog purity, noo noo cov ntsiab lus, pH tus nqi, thiab lwm yam ntsuas, kom ntseeg tau tias cov khoom zoo raws li cov qauv tsim nyog.

VII. Kev ntsuas kev nyab xeeb

Kev tsim cov txheej txheem ntawm sodium hydrosulfide nthuav tawm qee yam kev nyab xeeb, yog li kev ntsuas kev nyab xeeb yuav tsum tau ua:

1. Hydrogen sulfide roj yog tshuaj lom thiab teeb meem; Yog li ntawd, nws yog ib qho tseem ceeb uas yuav tsum nruj me ntsis tswj cov roj ntws tus nqi thiab cov tshuaj tiv thaiv kub los tiv thaiv cov pa paug thiab cov neeg ua hauj lwm lom tshwm sim.

2. Cov paib ceeb toom kev nyab xeeb thiab cov chaw tua hluav taws yuav tsum tau teeb tsa ntawm qhov chaw tsim khoom kom ntseeg tau tias cov neeg ua haujlwm muaj kev nyab xeeb thiab txhim kho kev muaj peev xwm teb thaum muaj xwm txheej ceev.

3. Cov neeg ua haujlwm yuav tsum tau txais kev cob qhia kev cob qhia kom nkag siab txog cov khoom ntawm cov khoom thiab cov txheej txheem kev ua haujlwm, ua kom muaj kev nyab xeeb thiab ruaj khov ntawm cov txheej txheem ua haujlwm.

VIII. Xaus

Raws li cov khoom siv tshuaj tseem ceeb, kev tsim cov sodium hydrosulfide yuav tsum muaj kev tswj hwm nruj ntawm cov khoom siv raw zoo, cov tshuaj tiv thaiv kab mob, thiab cov khoom lag luam kom ntseeg tau tias cov khoom zoo thiab cov txiaj ntsig ntawm cov khoom. Tsis tas li ntawd, nws yog ib qho tseem ceeb rau kev ntxiv dag zog rau kev siv thiab kev tswj xyuas kev nyab xeeb kom ntseeg tau tias muaj kev nyab xeeb thiab ruaj khov ntawm cov txheej txheem tsim khoom.
