Cov Txheej Txheem Tseem Ceeb ntawm Potassium Sulfate

Cov Txheej Txheem Mannheim is cov txheej txheem kev lag luam rau kev tsim cov K2SO4,ib qho kev sib xyaw ua ke ntawm 98% sulfuric acid thiab potassium chloride ntawm qhov kub siab nrog rau hydrochloric acid ua ib qho khoom siv ntxiv. Cov kauj ruam tshwj xeeb suav nrog kev sib xyaw potassium chloride thiab sulfuric acid thiab ua rau lawv sib xyaw ntawm qhov kub siab los ua potassium sulfate thiab hydrochloric acid.

Kev ua kom muaj pob zebskev faib tawmtsim cov potassium sulfate los ntawm kev ci cov alkali zoo li tung noob plhaub thiab cov tshauv cog, tom qab ntawd ua raws lileaching, filtering, concentrating, centrifugal sib cais thiab ziab kom tau txais potassium sulfate.

Kev teb ntawmCov tshuaj potassium chloridethiabSulfuric Acid ntawm qhov kub tshwj xeeb hauv qhov sib piv tshwj xeeb yog lwm txoj hauv kev kom tau txais potassium sulfate.Cov kauj ruam tshwj xeeb suav nrog kev yaj potassium chloride hauv dej sov, ntxiv sulfuric acid rau qhov kev tshuaj tiv thaiv, thiab tom qab ntawd crystallizing ntawm 100–140 ° C, ua raws li kev sib cais, neutralization, thiab ziab kom tsim tau potassium sulfate.

Cov txiaj ntsig ntawm Mannheim Potassium Sulfate

Cov txheej txheem Mennheim yog txoj kev tseem ceeb ntawm kev tsim cov potassium sulfate txawv teb chaws. Txoj kev txhim khu kev qha thiab zoo heev tsim cov potassium sulfate concentrated nrog cov dej solubility zoo dua. Cov kua qaub tsis muaj zog yog qhov tsim nyog rau cov av alkaline.

Cov Ntsiab Cai Tsim Khoom

Cov Txheej Txheem Tshuaj Tiv Thaiv:

1. Cov kua qaub sulfuric thiab potassium chloride raug ntsuas sib npaug thiab pub rau hauv chav ua haujlwm ntawm lub cub tawg Mannheim, qhov chaw uas lawv teb los tsim cov potassium sulfate thiab hydrogen chloride.

2. Qhov kev tshuaj tiv thaiv tshwm sim ua ob kauj ruam:

i. Kauj ruam thawj zaug yog exothermic thiab tshwm sim ntawm qhov kub qis dua.

ii. Kauj ruam thib ob cuam tshuam nrog kev hloov pauv ntawm potassium bisulfate mus rau potassium sulfate, uas yog endothermic muaj zog heev.

Kev Tswj Kub:

1. Cov tshuaj tiv thaiv yuav tsum tshwm sim ntawm qhov kub siab tshaj 268 ° C, nrog rau qhov zoo tshaj plaws yog 500-600 ° C kom ntseeg tau tias muaj txiaj ntsig zoo yam tsis muaj kev lwj ntawm cov kua qaub sulfuric ntau dhau.

2. Hauv kev tsim khoom tiag tiag, qhov kub ntawm cov tshuaj tiv thaiv feem ntau yog tswj ntawm 510-530 ° C rau kev ruaj khov thiab kev ua haujlwm zoo.

Kev Siv Kub:

1. Cov tshuaj tiv thaiv yog endothermic heev, xav tau kev muab cua sov tas mus li los ntawm kev hlawv roj ntuj.

2. Kwv yees li ntawm 44% ntawm lub cub tawg cua sov poob los ntawm phab ntsa, 40% raug nqa mus los ntawm cov pa roj tawm, thiab tsuas yog 16% siv rau qhov kev cuam tshuam tiag tiag.

Cov Ntsiab Lus Tseem Ceeb ntawm Cov Txheej Txheem Mannheim

Lub cub tawgtxoj kab uas hla yog qhov txiav txim siab ntawm lub peev xwm tsim khoom. Cov cub tawg loj tshaj plaws hauv ntiaj teb muaj txoj kab uas hla ntawm 6 meters.Tib lub sijhawm, kev tsav tsheb txhim khu kev qha yog qhov lav ntawm kev ua haujlwm tas mus li thiab ruaj khov.Cov khoom siv uas tsis yooj yim puas yuav tsum tiv taus qhov kub thiab txias siab, cov kua qaub muaj zog, thiab muaj kev hloov pauv cua sov zoo. Cov khoom siv rau cov txheej txheem sib tov yuav tsum tiv taus cua sov, xeb, thiab hnav.

Qhov Zoo ntawm Cov Pa Hydrogen Chloride:

1. Kev tswj xyuas me ntsis hauv chav ua haujlwm ua kom ntseeg tau tias huab cua thiab cov pa roj tsis ua rau cov hydrogen chloride tsis yaj.

2. Kev kaw thiab kev ua haujlwm zoo tuaj yeem ua tiav HCl concentration ntawm 50% lossis siab dua.

Cov Khoom Siv Raw:

1.Cov tshuaj potassium chloride:Yuav tsum ua tau raws li qhov yuav tsum tau ua ntawm cov dej noo, qhov loj ntawm cov khoom me me, thiab cov ntsiab lus ntawm potassium oxide kom ua tau zoo tshaj plaws rau kev ua haujlwm ntawm cov tshuaj tiv thaiv.

2.Sulfuric Acid:Yuav tsum muaj kev sib xyaw ua ke ntawm 99% rau kev ntshiab thiab kev sib xws.

Kev Tswj Kub:

1.Chav Ua Tshuaj Tiv Thaiv (510-530 ° C):Xyuas kom meej tias muaj kev teb tag nrho.

2.Chav Ua Kub Hnyiab:Sib npaug cov roj av rau kev hlawv kom zoo.

3.Kub ntawm roj tom qab:Tswj kom tiv thaiv kev thaiv cov pa tawm thiab xyuas kom meej tias nqus tau roj zoo.

Cov Txheej Txheem Ua Haujlwm

• Kev teb:Potassium chloride thiab sulfuric acid raug pub rau hauv chav tshuaj tiv thaiv tas li. Cov potassium sulfate uas tshwm sim raug tso tawm, txias, tshuaj ntsuam, thiab ua kom tsis muaj zog nrog calcium oxide ua ntej ntim.
• Kev Ua Haujlwm ntawm Cov Khoom Siv:
  • Cov roj hydrogen chloride kub siab raug txias thiab lim los ntawm ntau lub tshuab ntxuav thiab cov pej thuam nqus kom tsim tau cov kua qaub hydrochloric acid (31-37% HCl) hauv kev lag luam.
  • Cov pa roj tawm hauv qab raug kho kom ua tau raws li cov qauv ib puag ncig.

Cov Teeb Meem thiab Kev Txhim Kho

1. Kev Poob Kub:Cov cua sov tseem ceeb poob los ntawm cov pa tso pa tawm thiab phab ntsa cua sov, qhia txog qhov xav tau kev txhim kho cov txheej txheem rov qab cua sov.
2. Kev xeb ntawm cov khoom siv:Cov txheej txheem ua haujlwm nyob rau hauv qhov kub thiab txias siab thiab cov mob acidic, ua rau hnav thiab kev sib tw txij nkawm.
3. Kev Siv Cov Khoom Siv Hydrochloric Acid:Kev ua lag luam rau hydrochloric acid tuaj yeem puv nkaus, xav tau kev tshawb fawb txog lwm txoj kev siv lossis cov txheej txheem los txo cov khoom tsim tawm.

Cov txheej txheem tsim cov tshuaj potassium sulfate hauv Mannheim muaj ob hom kev tso pa roj pov tseg: cov pa roj hlawv los ntawm cov roj ntuj thiab cov khoom siv hydrogen chloride.

Cov Pa Hluav Taws Xob:

Qhov kub ntawm cov pa tawm ntawm lub cub tawg feem ntau yog li ntawm 450 ° C. Cov cua sov no raug xa mus los ntawm lub tshuab rov ua dua ua ntej raug tso tawm. Txawm li cas los xij, txawm tias tom qab pauv cua sov, qhov kub ntawm cov pa tawm tseem nyob ntawm kwv yees li 160 ° C, thiab cov cua sov seem no raug tso tawm mus rau hauv huab cua.

Cov Khoom Siv Hydrogen Chloride Gas:

Cov pa roj hydrogen chloride raug txhuam hauv lub pej thuam ntxuav sulfuric acid, nqus tau hauv lub tshuab nqus dej poob, thiab ntxuav hauv lub pej thuam ntxuav pa tawm ua ntej tso tawm. Cov txheej txheem no tsim tau 31% hydrochloric acid., nyob rau hauv uas siab duakev sib xyaw ua ke tuaj yeem ua rau muaj kev tso pa tawmtsis txog raucov qauv thiab ua rau muaj qhov tshwm sim "tail drag" hauv cov pa tawm.Yog li ntawd, lub sijhawm tiag tiagkua qaub hydrochloric kev ntsuas qhov concentration hloov tseem ceeb hauv kev tsim khoom.

Cov kev ntsuas hauv qab no yuav ua tau kom muaj txiaj ntsig zoo dua:

Txo Qhov Acid Concentration: Txo qhov acid concentration thaum lub sijhawm nqus dejnroginline density meter rau kev saib xyuas kom meej.

Ua kom cov dej ntws ntau ntxiv: Txhim kho cov dej ntws hauv cov khoom nqus dej kom zoo dua qub.

Txo Qhov Kev Thauj Khoom ntawm Lub Tsev Lim Pa Tawm: Ua kom zoo dua cov haujlwm kom txo qhov kev thauj khoom ntawm lub kaw lus lim.

Los ntawm cov kev hloov kho no thiab kev ua haujlwm kom raug raws sijhawm, qhov tshwm sim ntawm kev rub tus Tsov tus tw tuaj yeem raug tshem tawm, kom ntseeg tau tias cov pa phem ua tau raws li cov qauv xav tau.
