Abstract

The invention relates to industrial by-product gypsum reduction equipment. The industrial by-product gypsum reduction equipment comprises a kiln head, a kiln tail, a roller, a feeding device, a discharging opening, a tail air-intake pipe, a power transmission device and a supporting device. Anhydrite gypsum and hemi-hydrate gypsum are conveyed into the sealed roller, meanwhile vapor is conveyed into the sealed roller, under certain pressure condition, the anhydrite gypsum, the hemi-hydrate gypsum and the vapor are mixed and uniformly stirred in the sealed roller, and the anhydrite gypsum is reduced into hemi-hydrate gypsum by using water of the hemi-hydrate gypsum and the vapor. Therefore, the problem of a plurality of anhydrite gypsum products of the current gypsum drying machine is effectively solved, the rate of transferring industrial by-product gypsum into hemi-hydrate gypsum is effectively improved, and the production efficiency of hemi-hydrate gypsum by the gypsum drying machine is improved.

Description

technical field

[0001] The invention relates to the technical field of gypsum production equipment, in particular to a reduction equipment for industrial by-product gypsum, especially phosphogypsum. Background technique

[0002] Gypsum is a chemical composition of calcium sulfate containing crystal water. In daily life, gypsum is divided into natural gypsum and chemical gypsum. Natural gypsum is a mineral containing two crystal water. Chemical gypsum is used when producing fertilizers and other chemical raw materials. The waste produced, with the improvement of the emission requirements of coal-fired boilers, the by-product of the desulfurization process is called desulfurization gypsum; the waste gypsum produced by the production of fertilizers and other phosphides is called phosphogypsum because it contains phosphorus oxide. The application of building materials is mostly to calcinate raw gypsum containing two crystal waters into gypsum containing half crystal water, commo...
