Embodiment Construction

[0022] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. It should be noted here that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation to the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0023] Such as figure 1 As shown, the gypsum evaporative cooling and aging tower is mainly composed of an evaporation chamber 9, a lowering chamber 18, and a aging chamber 15. Between the evaporation chamber 9 and the cylinder 12 is the lowering chamber 18, and above the evaporation chamber 9 is the aging chamber 15.

[0024] The evaporation chamber 9 is provided with an air inlet 1, a spray system 7, a heat exchange packing 6 and a support frame 10. The air inlet 1 is located at...

Abstract

The invention discloses a gypsum evaporation cooling aging tower. An evaporation chamber is arranged in the center of a cylinder; a cooling chamber is formed between the inner wall of the cylinder andthe outer wall of the evaporation chamber; the evaporation chamber is communicated with an aging chamber; a multi-stage spraying system and a multi-layer filler with a heat exchange effect are arranged in the evaporation chamber; the spraying systems and the fillers are alternately arranged at intervals; part of heat of materials needing to be cooled is utilized and absorbed; a quantity of liquidwater is evaporated, evaporated water vapor is used for ageing the material, so that the amount of air used by adopting an all-air cooling and aging process is reduced, the purpose of reducing consumption is achieved, and especially for treating building gypsum with high soluble anhydrous gypsum content, the positive effects on the aspects of production process control, product quality stabilityand the like in the field of gypsum calcination can be achieved. Due to the two functions of cooling and aging, the needed installed power is far lower than that of an existing gypsum calcination linepost-cooling device.

Description

Technical field [0001] The invention belongs to the field of building materials preparation, and specifically relates to equipment for rapid cooling and aging of building gypsum after calcination, in particular to equipment for rapid cooling and aging of building gypsum with high soluble anhydrous calcium sulfate content. Background technique [0002] In the production process of building gypsum powder, calcium sulfate dihydrate (green gypsum) is calcined into calcium sulfate hemihydrate (gypsum of Paris). However, the phase composition of gypsum is relatively complicated. In addition to the main component of calcium sulfate hemihydrate, the building gypsum powder just after calcination also contains a certain amount of soluble anhydrous calcium sulfate and a small amount of unreacted calcium sulfate dihydrate and other unstable or harmful substances. phase. In downstream applications, especially in the application of plastering mortar, because of the high content of soluble anh...
