Mokhoa oa Mannheim bakeng sa Potassium Sulfate (K₂SO₄) Tlhahiso

Mekhoa e Meholo ea Tlhahiso ea Potassium Sulfate

Mokhoa oa Mannheim is ts'ebetso ea indasteri bakeng sa tlhahiso ea K2SO4,karabelo ea ho bola pakeng tsa 98% sulfuric acid le potassium chloride maemong a phahameng a mocheso le as a byproduct hydrochloric acid. Mehato e tobileng e kenyelletsa ho kopanya potassium chloride le sulfuric acid le ho li arabela ka mocheso o phahameng ho etsa potassium sulfate le hydrochloric acid.

Crystallizationseparatione hlahisa potassium sulfate ka ho halika alkaline joalo ka khetla ea peo ea tung le molora oa semela, ebe e lateloa keleaching, filtering, concentrate, centrifugal karohano le ho omisa ho fumana potassium sulfate.

Boitšoaro baPotassium ChlorideleAsiti ea sulfuric ka mocheso itseng ka karo-karolelano e itseng ke mokhoa o mong oa ho fumana potassium sulfate.Mehato e tobileng e kenyelletsa ho qhibiliha potassium chloride metsing a futhumetseng, ho eketsa sulfuric acid bakeng sa karabelo, ebe e khanyetsa ka 100-140 ° C, e lateloa ke karohano, neutralization, le ho omisa ho hlahisa potassium sulfate.

Melemo ea Mannheim Potassium Sulfate

Mokhoa oa Mennheim ke mokhoa o ka sehloohong oa tlhahiso ea potassium sulfate mose ho maoatle. Mokhoa o ka tšeptjoang le o rarahaneng o hlahisa sulfate ea potasiamo e tsitsitseng e nang le ho qhibiliha ha metsi ho phahameng. Tharollo e fokolang ea asiti e loketse mobu oa alkaline.

Melao-motheo ea Tlhahiso

Mokhoa oa ho arabela:

1. Asiti ea sulfuric le potassium chloride li lekanngoa ka metered le ho lekana ka kamoreng ea ho arabela ea sebōpi sa Mannheim, moo li itšoarang ho hlahisa potassium sulfate le hydrogen chloride.

2. Karabelo e etsahala ka mehato e 'meli:

ke. Mohato oa pele ke exothermic 'me e etsahala ka mocheso o tlase.

ii. Mohato oa bobeli o kenyelletsa phetoho ea potassium bisulfate ho potasiamo sulfate, e leng endothermic ka matla.

Taolo ea Mocheso:

1. Boitšoaro bo tlameha ho etsahala ka mocheso o ka holimo ho 268 ° C, 'me sebaka se nepahetseng ke 500-600 ° C ho netefatsa katleho ntle le ho bola ho feteletseng ha sulfuric acid.

2. Tlhahisong ea sebele, mocheso oa karabelo o laoloa ka tloaelo pakeng tsa 510-530 ° C bakeng sa botsitso le katleho.

Tšebeliso ea Mocheso:

1. Karabelo ke endothermic haholo, e hloka phepelo e tsitsitseng ea mocheso ho tsoa ho tukang ha khase ea tlhaho.

2. Hoo e ka bang 44% ea mocheso oa sebōpi o lahleheloa ke marako, 40% e nkoa ke likhase tsa ho tsoa, ​​​​'me ke 16% feela e sebelisetsoang karabelo ea sebele.

Lintlha tsa bohlokoa tsa Ts'ebetso ea Mannheim

Sebopibophara ke ntlha ea bohlokoa ea matla a tlhahiso. Libōpi tse kholo ka ho fetisisa lefatšeng ka bophara li na le bophara ba limithara tse 6.Ka nako e ts'oanang, mokhoa o ka tšeptjoang oa ho khanna ke tiiso ea karabelo e tsoelang pele le e tsitsitseng.Lisebelisoa tsa refractory li tlameha ho mamella mocheso o phahameng, li-acid tse matla, 'me li fane ka phetisetso e ntle ea mocheso. Lisebelisoa tsa lisebelisoa tse susumetsang li tlameha ho mamella mocheso, kutu le ho senyeha.

Boleng ba Khase ea Hydrogen Chloride:

1.Ho boloka vacuum e nyenyane ka kamoreng ea ho arabela ho tiisa hore moea le likhase tsa flue ha li hlapolle hydrogen chloride.

2. Ho tiisoa ka nepo le ts'ebetso ho ka fihlela likhakanyo tsa HCl tsa 50% kapa ho feta.

Litlhaloso tsa Raw Material:

1.Potassium Chloride:E tlameha ho finyella litlhoko tse khethehileng tsa mongobo, boholo ba likaroloana, le litlhoko tsa dikahare tsa potasiamo bakeng sa katleho e nepahetseng.

2.Asiti ea sulfuric:E hloka concentration ea 99% bakeng sa bohloeki le karabelo e tsitsitseng.

Taolo ea Mocheso:

1.Kamore ea Karabelo (510-530°C):E netefatsa karabelo e felletseng.

2.Mohaho oa Mollo:E leka-lekanya ho kenya khase ea tlhaho bakeng sa ho tuka hantle.

3.Thempereichara ea Khase ea Mohatla:E laoloa ho thibela litšitiso tsa ho tsoa le ho netefatsa ho monya ha khase ka katleho.

Mokhoa oa ho sebetsa

• Maikutlo:Potassium chloride le sulfuric acid li lula li fepeloa ka kamoreng ea karabelo. Potasiamo sulfate e hlahisoang e ea ntšoa, e pholisoe, e hlahlojoe, 'me e fokotsoe ka calcium oxide pele e phutheloa.
• Ho sebetsana le Sehlahisoa:
  • Khase ea hydrogen chloride ea mocheso o phahameng e pholile ebe e hloekisoa ka letoto la li-scrubber le litora tsa ho monya ho hlahisa hydrochloric acid ea boemo ba indasteri (31-37% HCl).
  • Likhase tsa mohatla li tšoaroa ho fihlela maemo a tikoloho.

Mathata le Lintlafatso

1. Tahlehelo ea Mocheso:Mocheso o moholo o lahleheloa ke likhase tsa ho qeta le marako a sebōpi, ho totobatsa tlhokahalo ea mekhoa e ntlafetseng ea ho tsosolosa mocheso.
2. Equipment Corrosion:Mokhoa ona o sebetsa tlas'a mocheso o phahameng le maemo a acidic, a lebisang ho mathata a ho apara le ho hlokomela.
3. Tšebeliso ea Hydrochloric Acid By-Sehlahisoa:Mmaraka oa hydrochloric acid o ka tlala, o hloka hore lipatlisiso li sebelisoe ka mekhoa e meng kapa mekhoa ea ho fokotsa tlhahiso ea sehlahisoa.

Ts'ebetso ea tlhahiso ea Mannheim potassium sulfate e kenyelletsa mefuta e 'meli ea likhase tse litšila: mosi o tukang o tsoang khase ea tlhaho le khase ea hydrogen chloride.

Combustion Exhaust:

Thempereichara ea mosi oa mollo hangata e ka ba 450°C. Mocheso ona o fetisoa ka mochine o hloekisang pele o lokolloa. Leha ho le joalo, esita le ka mor’a ho fapanyetsana mocheso, mocheso oa khase ea ho ntša metsi o lula o le hoo e ka bang 160°C, ’me mocheso ona o setseng o lokolloa sepakapakeng.

Motsoako oa Khase ea Hydrogen Chloride:

Khase ea hydrogen chloride e kenella ka har'a tora ea ho hlatsoa asiti ea sulfuric, e kenella ka har'a mohanyi oa filimi e oelang, 'me e hloekisoa tora ea tlhoekiso ea khase pele e lokolloa. Mokhoa ona o hlahisa 31% hydrochloric acid, eo ho eona hodimoho tsepamisa mohopolo ho ka lebisa ho mesieseng ho fihlelamaemo le ho baka ketsahalo ya "mohatla" moferong.Ka hona, nako ea sebelehydrochloric acid tekanyo ya mahloriso fetoha bohlokoa tlhahisong.

Mehato e latelang e ka nkuoa bakeng sa litlamorao tse ntle:

Fokotsa Boiketlo ba Asiti: Fokotsa khatello ea asiti nakong ea ts'ebetso ea ho monyakameter density meter bakeng sa ho beha leihlo ka nepo.

Eketsa Bophahamo ba Metsi a Potolohang: Ntlafatsa phallo ea metsi ka har'a sebapi sa filimi se oelang ho ntlafatsa ts'ebetso ea ho monya.

Fokotsa Mojaro ho Exhaust Gas Purification Tower: Ntlafatsa ts'ebetso ho fokotsa moroalo tsamaisong ea tlhoekiso.

Ka liphetoho tsena le ts'ebetso e nepahetseng ha nako e ntse e ea, ketsahalo ea ho hula mohatla e ka felisoa, ho netefatsa hore mesi e finyella litekanyetso tse hlokahalang.
