Problems solved by technology

[0004] 1. The salt field process is complex; the salt field process of the prior art comprises five mutually independent salt-out processes in total, i.e. sodium chloride section, epsom salt section, potassium halite section, carnallite section and old brine section. A total of five independent salt pans for different salt precipitation processes need to be set up, so the salt pan process is complicated

Embodiment Construction

[0025] An improved method for preparing potassium-magnesium sulfate fertilizer with potassium-containing magnesium sulfate subtype brine, comprising the following steps:

[0026] ①Inject the potassium-containing magnesium sulfate subtype brine into the salt field in the sodium chloride stage and dry it on the natural beach to meet the brine injection standard in the salt field in the potassium mixed salt stage. After the salt field brine in the sodium chloride stage, inject the salt field brine in the sodium chloride stage into the potassium mixed salt After the natural beach in the stage salt field is sun-dried to meet the brine discharge standard of the potash-mixed salt stage salt field, inject the potassium-mixed salt stage salt field brine into the old brine stage salt field;

[0027] The crystallization out of the salt field in the potassium mixed salt stage is the potassium mixed salt, and the weight percentage ratio of sulfate ions and potassium ions in the potassium mi...

Abstract

The improved process of preparing magnesium potassium sulfate fertilizer with bittern containing potassium and magnesium sulfate includes the following steps: 1. spreading and shinning the bittern to form mixed potassium salt; 2. crushing and grinding the mineral of mixed potassium salt; 3. adding fresh water or slight salty water in the amount one 0.3-0.6 times the floated mixed potassium salt to convert the slurry; 4. mixing the slurry and floating chemical to float and obtain floated foamed concentrate; 5. washing the concentrate with fresh water or slight salty water; and 6. solid-liquid separating the concentrate to obtain solid concentrate and drying the solid concentrate to obtain magnesium potassium sulfate fertilizer product. The process of the present invention is simple, and has high quality of the produced magnesium potassium sulfate fertilizer.

Description

technical field [0001] The invention relates to a method for preparing potassium-magnesium sulfate fertilizer, in particular to an improved method for preparing potassium-magnesium sulfate fertilizer by using potassium-containing magnesium sulfate subtype brine. Background technique [0002] The molecular formula of potassium magnesium sulfate fertilizer is K 2 SO 4 · Mg 2 SO 4 ·6H 2 O, whose scientific name is kaleinite, is a new type of agricultural fertilizer. [0003] The inventor of the patent application of the present invention thinks that the Chinese invention patent application with the application number 02143641.X and the name "Method for Producing Potassium Sulphate from Potassium-containing Magnesium Sulfate Subtype Brine" is the closest existing patent application of the present invention Technology, in this prior art, jalebisite is its intermediate product; There is following problem in this prior art and the part that the present invention repeats: [0...
