Description

Technical Field

[0001] The utility model relates to the technical field of desulfurized gypsum production, and more specifically to a quantitative mixing device for desulfurized gypsum production. Background Art

[0002] Desulfurized gypsum is also called flue gas desulfurized gypsum, sulfur gypsum or FGD gypsum. Its main component is the same as natural gypsum, which is calcium sulfate dihydrate CaSO4·2H2O, with a content of ≥93%. Desulfurized gypsum is a by-product of the FGD process. The FGD process is a technology that uses lime-limestone to recover sulfur dioxide from flue gas from coal or oil combustion. This technology is to grind lime-limestone into slurry, and pass the dust-removed flue gas containing SO2 through a slurry scrubber to remove SO2. The lime slurry reacts with SO2 to produce calcium sulfate and calcium sulfite. Calcium sulfite is oxidized and converted into calcium sulfate to obtain industrial by-product gypsum, called desulfurized gypsum, which is widely used in building materials and other industries.

[0003] The existing desulfurization gypsum needs to be mixed during the processing. During the mixing process, certain catalysts or other related materials need to be added. The existing desulfurization gypsum mixing equipment cannot accurately control the weight of the materials put in, which can easily cause too much or too little addition of a certain material, which will cause a large error in the material ratio and affect the production of desulfurization gypsum.

[0004] The existing desulfurized gypsum mixing equipment has the above-mentioned problems. In view of this, we propose a quantitative mixing equipment for desulfurized gypsum production. Utility Model Content
