Mannheim Txheej Txheem rau Potassium Sulfate (K2SO4) Ntau lawm
Cov Txheej Txheem Tseem Ceeb ntawm Potassium Sulfate
Mannheim txheej txheem is Cov txheej txheem kev lag luam rau kev tsim cov K2SO4,Cov tshuaj tiv thaiv decomposition ntawm 98% sulfuric acid thiab potassium chloride ntawm qhov kub thiab txias nrog rau cov khoom siv hydrochloric acid. Cov kauj ruam tshwj xeeb suav nrog kev sib xyaw poov tshuaj chloride thiab sulfuric acid thiab ua rau lawv nyob rau qhov kub thiab txias los tsim cov poov tshuaj sulfate thiab hydrochloric acid.
Crystallizationskev sib caistsim cov poov tshuaj sulfate los ntawm roasting ntawm alkali zoo li tung noob plhaub thiab tsob ntoo tshauv, ces ua raws lileaching, filtering, concentrating, centrifugal sib cais thiab ziab kom tau poov tshuaj sulfate.
Cov tshuaj tiv thaiv ntawmPotassium ChloridethiabSulfuric Acid ntawm qhov kub thiab txias hauv ib qho piv txwv yog lwm txoj hauv kev kom tau txais poov tshuaj sulfate.Cov kauj ruam tshwj xeeb suav nrog cov tshuaj tua kab mob potassium chloride hauv dej sov, ntxiv sulfuric acid rau cov tshuaj tiv thaiv, thiab tom qab ntawd crystallizing ntawm 100-140 ° C, tom qab ntawd sib cais, nruab nrab, thiab ziab kom tsim cov poov tshuaj sulfate.
Qhov zoo ntawm Mannheim Potassium Sulfate
Mennheim txheej txheem yog thawj txoj hauv kev ntawm potassium sulfate ntau lawm txawv teb chaws. Txoj kev txhim khu kev qha thiab sophisticated tsim cov concentrated poov tshuaj sulfate nrog superior dej solubility. Cov kua qaub tsis muaj zog yog tsim rau alkaline av.
Cov Cai Tsim Khoom
Cov txheej txheem tshuaj tiv thaiv:
1. Sulfuric acid thiab potassium chloride yog proportionally metered and evenly feeded into the reaction chamber of the Mannheim furnace, where they react to produce potassium sulfate and hydrogen chloride.
2. Cov tshuaj tiv thaiv tshwm sim hauv ob kauj ruam:
i. Thawj kauj ruam yog exothermic thiab tshwm sim ntawm qhov kub thiab txias.
ii. Cov kauj ruam thib ob cuam tshuam nrog kev hloov pauv ntawm potassium bisulfate mus rau potassium sulfate, uas yog endothermic.
Kev tswj qhov kub thiab txias:
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 kev ua haujlwm tsis muaj sulfuric acid ntau dhau.
2. Nyob rau hauv qhov tseeb ntau lawm, cov tshuaj tiv thaiv kub yog feem ntau tswj ntawm 510-530 ° C rau stability thiab efficiency.
Kev siv cua sov:
1. Cov tshuaj tiv thaiv yog endothermic heev, yuav tsum tau cov khoom siv hluav taws xob zoo ib yam los ntawm kev sib xyaw roj.
2. Nyob ib ncig ntawm 44% ntawm lub cub tawg cua sov yog poob los ntawm cov phab ntsa, 40% yog nqa tawm los ntawm cov pa roj, thiab tsuas yog 16% yog siv rau cov tshuaj tiv thaiv tiag tiag.
Qhov tseem ceeb ntawm txoj kev Mannheim
Rauvtxoj kab uas hla yog qhov txiav txim siab ntawm kev tsim muaj peev xwm. Lub qhov cub loj tshaj plaws hauv ntiaj teb muaj txoj kab uas hla ntawm 6 meters.Nyob rau tib lub sij hawm, txhim khu kev qha tsav tsheb yog lub guarantee ntawm kev nruam thiab ruaj khov cov tshuaj tiv thaiv.Cov ntaub ntawv refractory yuav tsum tiv taus qhov kub thiab txias, muaj zog acids, thiab muab cov cua sov zoo. Cov khoom siv rau kev sib tsoo tshuab yuav tsum tiv taus cua sov, corrosion, thiab hnav.
Hydrogen Chloride Gas Zoo:
1.Kev tuav lub tshuab nqus tsev me me hauv cov tshuaj tiv thaiv chamber kom ntseeg tau tias cov pa roj cua thiab cov pa taws tsis ua rau cov hydrogen chloride dilute.
2.Kev sib khi zoo thiab kev ua haujlwm tuaj yeem ua tiav HCl ntau ntawm 50% lossis siab dua.
Raw Material Specifications:
1.Potassium Chloride:Yuav tsum ua kom tau raws li cov dej noo tshwj xeeb, qhov loj me, thiab cov ntsiab lus ntawm cov poov tshuaj oxide rau kev pom kev ua haujlwm zoo.
2.Sulfuric Acid:Yuav tsum muaj concentration ntawm 99% rau purity thiab zoo ib yam tshuaj tiv thaiv.
Kev tswj qhov kub thiab txias:
1.Reaction Chamber (510-530 ° C):Ua kom tiav cov tshuaj tiv thaiv.
2.Combustion Chamber:Ntsuas cov khoom siv hluav taws xob zoo rau kev sib xyaw kom zoo.
3.Tail Gas Kub:Tswj tau los tiv thaiv cov pa tawm blockages thiab xyuas kom cov pa nqus tau zoo.
Txheej Txheem Ua Haujlwm
- Teb:Potassium chloride thiab sulfuric acid tau txuas ntxiv mus rau hauv cov tshuaj tiv thaiv chamber. Qhov tshwm sim ntawm cov poov tshuaj sulfate yog tawm, txias, tshuaj xyuas, thiab nruab nrab nrog calcium oxide ua ntej ntim.
- By-product Handling:
- High-temperature hydrogen chloride gas yog txias thiab purified los ntawm ib tug series ntawm scrubbers thiab nqus yees los tsim industrial-qib hydrochloric acid (31-37% HCl).
- Tail gas emissions raug kho kom ua tau raws li cov qauv ib puag ncig.
Kev sib tw thiab kev txhim kho
- Thaum tshav kub kub:Cov cua kub tseem ceeb tau ploj los ntawm cov pa hluav taws xob thiab cov phab ntsa ntawm lub cub tawg, qhia txog qhov xav tau kev txhim kho cua sov kom zoo dua qub.
- Khoom siv Corrosion:Cov txheej txheem ua haujlwm nyob rau hauv qhov kub thiab txias thiab acidic tej yam kev mob, ua rau hnav thiab tu cov teeb meem.
- Hydrochloric Acid By-product Siv:Kev ua lag luam rau hydrochloric acid tuaj yeem saturated, xav tau kev tshawb fawb rau lwm txoj hauv kev siv lossis kev txo qis los ntawm cov khoom tsim tawm.
Mannheim poov tshuaj sulfate cov txheej txheem tsim muaj ob hom pov tseg cov pa emissions: combustion tso tawm los ntawm natural gas thiab byproduct hydrogen chloride gas.
Combustion Exhaust:
Qhov kub ntawm cov combustion tso tawm feem ntau yog nyob ib ncig ntawm 450 ° C. Cov cua sov no yog hloov los ntawm lub tshuab recuperator ua ntej tso tawm. Txawm li cas los xij, txawm tias tom qab kev sib pauv cua sov, cov pa cua kub tseem nyob ntawm kwv yees li 160 ° C, thiab cov cua sov seem no tau tso rau hauv qhov chaw.
Byproduct Hydrogen Chloride Gas:
Cov roj hydrogen chloride tau siv tshuaj txhuam hauv cov tshuaj sulfuric acid ntxhua khaub ncaws, nqus hauv cov khoom poob-zaj duab xis absorber, thiab purification nyob rau hauv lub tso pa purification ntauwd ua ntej yuav tawm. Cov txheej txheem no tsim 31% hydrochloric acid, hauv siab duaconcentration tuaj yeem ua rau emissionstsis mus txogcov qauv thiab ua rau "tail drag" phenomenon nyob rau hauv lub tso pa tawm.Yog li ntawd, lub sijhawm tiag tiaghydrochloric acid kev ntsuas concentration tig tseem ceeb hauv kev tsim khoom.
Cov kev ntsuas hauv qab no tuaj yeem ua rau muaj txiaj ntsig zoo dua:
Txo Acid Concentration: Txo cov acid concentration thaum lub sij hawm nqusnroginline ceev meter rau kev saib xyuas kom raug.
Ua kom cov dej ntws tawm: Txhim kho cov dej ntws hauv qhov poob-zaj duab xis absorber los txhim kho kev nqus dej.
Txo cov Load ntawm Cov Pa Roj Hmab purification Ntauwd: Ua kom zoo rau kev ua haujlwm kom txo tau lub nra ntawm lub purification system.
Los ntawm cov kev hloov kho thiab kev ua haujlwm kom raug raws sijhawm, tus Tsov tus tw rub tshwm sim tuaj yeem raug tshem tawm, kom ntseeg tau tias emissions ua tau raws li cov qauv xav tau.
