| titleOfInvention | The method of saltcake refined brine and preventing scaring |
| abstract | <b> the present invention relates to a kind of salt solution preparation technology, particularly a kind of brine rectification process.In once reactor, add crude brine, grey newborn metabisulfite solution make crude brine, ash breast and sodium sulfate hybrid reaction in reactor; Reaction solution in once reactor delivers to primary brine settling tank through chute, in a settling tank, primary purification salt solution and salt slurry carry out solid-liquid separation, from clarification refined brine of a settling tank top extraction, deliver to secondary refining reactor and carry out deliming, primary brine settling tank point discharge salt slurry and once reactor discharge silt are delivered to mud cleaning bucket and are washed, and reclaim wherein crude salt; After sulfate radical content in metabisulfite solution increases, equipment and pipeline form calcium sulfate scaling in various degree and in primary brine settling tank, add low-concentration alkali liquor after causticization for eliminating fouling.Avoid production equipment system fouling, solvay soda process soda manufacture lime soda ash salt refining method is improved.</b> |
