Gypsum cooling and aging process
The invention discloses a gypsum cooling and aging process. The process comprises the following steps: (1) quantitatively conveying a high-temperature building gypsum raw material containing soluble anhydrous calcium sulfate to a cooling chamber; (2) providing cold air for a cooling chamber to achieve the cooling effect, performing gas-solid mixing in the cooling chamber, generating a gas-solid mixture, and inputting water mist and the cold air into an evaporation chamber, and generating gaseous damp and hot airflow under the heat exchange effect of liquid water in the evaporation chamber andthe cooling chamber; (3) the gas-solid mixture and warm air flow enter an aging chamber to be subjected to a gas-liquid-solid three-phase mixing aging reaction, along with secondary gas-solid mixing cooling, part of heat needing to be cooled of the materials is used for evaporating liquid water by fully utilizing the heat of the hot materials, and the liquid water evaporation needs a large amountof latent heat of vaporization to absorb part of the heat of the materials so that the cooling effect is achieved; and meanwhile, the evaporated liquid water is in direct contact with the material ina water vapor form so that the situations of bonding, non-uniform aging and the like caused by direct contact between the liquid fog drops and the material are avoided, and the use amount of wet air is reduced.
本发明公开了一种石膏降温陈化工艺，步骤是：(1)含有可溶性无水硫酸钙的高温建筑石膏原料定量送至降温室；(2)向降温室提供冷空气以起降温作用，在降温室内进行气固混合，产生气固混合料，同时，向蒸发室输入水雾和冷空气，蒸发室的液态水与降温室进行热交换的作用下，产生气态湿热气流；(3)气固混合料与温热气流进入陈化室进行气液固三相混合陈化反应，并伴随二次气固混合降温发生，通过充分利用热物料的热量，将物料需要降温的部分热量用来蒸发液态水，液态水蒸发需要大量的汽化潜热，吸收一部分物料的热量，实现降温效果；同时蒸发的这部分液态水以水蒸气形式与物料直接接触，既避免了液态雾滴与物料直接接触造成的粘结、陈化不均等情况，又减少了湿空气的用量。
