Lim xovxwm: Lim xovxwm kuj yog ib qho khoom siv pom zoo. Nws siv qee qhov siab rau cov khoom kom tso cai rau cov kua kom dhau los ntawm cov lim nruab nrab, thaum cov khoom impurities khaws cia rau hauv cov lim nruab nrab. Lub lim xovxwm muaj qhov zoo ntawm kev pom zoo thiab kev siv dav dav.
3. Cov khoom siv evaporation
Cov khoom siv evaporation yog siv los mloog cov tshuaj phosphoric acid. Cov khoom siv evaporation feem ntau suav nrog evaporators, condensers, thiab lwm yam.
Evaporator: Cov evaporator yog cov khoom tseem ceeb ntawm cov khoom siv evaporation. Nws ua kom sov cov tshuaj phosphoric acid kom evaporate cov dej hauv nws, yog li ua kom cov concentration ntawm phosphoric acid. Tus tsim ntawm evaporator yuav tsum tau coj mus rau hauv tus account yam xws li cua sov txoj kev, evaporation efficiency, thiab cov ntaub ntawv fluidity.
Condenser: Lub condenser yog siv los condense cov chav generated thaum lub sij hawm evaporation txheej txheem rau hauv cov kua. Tus tsim ntawm lub condenser yuav tsum tau coj mus rau hauv tus account yam xws li txias txoj kev, condensation efficiency, thiab cov khoom siv.
4. Cov khoom siv thauj khoom
Cov khoom siv thauj khoom yog siv los thauj cov khoom ntawm ntau qhov sib txuas. Cov khoom siv conveying feem ntau suav nrog txoj siv conveyors, ntsia hlau conveyors, twj, thiab lwm yam.
Siv Conveyor: Siv conveyor yog cov khoom siv dav siv. Nws thauj khoom los ntawm ib qho chaw mus rau lwm qhov los ntawm kev txav ntawm txoj siv. Siv conveyor muaj qhov zoo ntawm qhov loj conveying muaj peev xwm, ntev conveying nrug thiab ua haujlwm yooj yim.
Ntsia Hlau Conveyor: Ntsia Hlau Conveyor kuj yog ib qho khoom siv dav dav. Nws thauj khoom los ntawm ib qho chaw mus rau lwm qhov los ntawm kev sib hloov ntawm cov ntsia hlau. Ntsia hlau conveyor muaj qhov zoo ntawm qhov loj conveying muaj peev xwm, luv conveying nrug thiab yooj yim qauv.
Pump: Lub twj tso kua mis yog ib yam khoom siv los thauj cov kua. Hauv kev tsim cov phosphoric acid, cov twj siv feem ntau yog siv los thauj phosphoric acid tov ntawm ib lub cuab yeej mus rau lwm qhov. Kev xaiv cov twj tso kua mis yuav tsum coj mus rau hauv tus account yam xws li tus nqi ntws, lub taub hau, thiab cov khoom ntawm cov khoom.
5. Lwm yam khoom siv
Ntxiv nrog rau cov khoom siv saum toj no, phosphoric acid ntau lawm kab kuj yuav tsum tau nruab nrog qee yam khoom siv, xws li cov cuab yeej cia, cov cuab yeej ntsuas ntsuas, cov cuab yeej ntsuas, thiab lwm yam.
Cov khoom siv khaws cia: siv los khaws cov ntaub ntawv xws li phosphate ore, sulfuric acid, phosphoric acid, thiab lwm yam. Kev tsim cov khoom siv khaws cia yuav tsum coj mus rau hauv tus account yam xws li qhov xwm ntawm cov khoom, lub peev xwm cia, thiab kev nyab xeeb.
Cov cuab yeej ntsuas: siv los ntsuas qhov ntsuas tsis xws li tus nqi ntws thiab qhov hnyav ntawm cov khoom. Qhov tseeb ntawm cov cuab yeej ntsuas ntsuas ncaj qha cuam tshuam rau qhov zoo thiab kev ua haujlwm ntawm phosphoric acid ntau lawm.
Cov cuab yeej kuaj xyuas: siv los txheeb xyuas ntau yam tsis sib xws hauv cov txheej txheem phosphoric acid ntau lawm, xws li kub, siab, concentration, thiab lwm yam.
