Problems solved by technology
[0004] The inventors of the above-mentioned related technologies believe that there are the following defects: when a large amount of materials are heated in the furnace body, the steam exchange pipe has a better heating effect on the material near the steam exchange pipe, but the heating effect on the material far away from the steam exchange pipe is poor. A large amount of materials cannot be heated evenly, which reduces the effect of heating and calcining the materials

Description
technical field [0001] The application relates to the field of industrial product production equipment, in particular to a desulfurized gypsum calciner. Background technique [0002] Desulfurization gypsum is also called flue gas desulfurization gypsum, sulfur gypsum or FGD gypsum, and its main components are the same as natural gypsum. Desulfurization gypsum is an industrial by-product gypsum obtained by coal or oil-burning industrial enterprises after treating sulfur dioxide in flue gas. The calcination of desulfurization gypsum is mainly divided into two categories: dry method and wet method. The product produced is α gypsum powder and beta gypsum powder. The object of our research is mainly building gypsum powder, that is, β gypsum powder. Gypsum stone or industrial by-product gypsum exists in the form of calcium sulfate dihydrate. There are two crystal waters in its molecular formula, and only one half of crystal water is removed to form half water. Calcium sulfate ha...
