Production process of low-alkalinity sulphoaluminate cement
The invention discloses a low-alkalinity sulphoaluminate cement production process, and relates to the technical field of cement production processes, and the low-alkalinity sulphoaluminate cement production process comprises the following steps: step 1, raw material pretreatment, step 2, raw material homogenization, step 3, high-temperature calcination, and step 4, cooling homogenization storage. Through cooperation of the preheating sleeve, the heat energy recovery sleeve, the water inlet assembly, the water storage tank, the hot water lead-out pipe and the recovery pipe, firstly, gas carrying a large amount of heat and dust is extracted into the heat energy recovery sleeve through the dust extraction assembly, and then water stored in the water storage tank is extracted into the heat energy recovery sleeve through the water inlet assembly; the water in the preheating device exchanges heat with gas carrying heat, water with high temperature after heat exchange flows into the preheating sleeve through the hot water leading-out pipe to preheat raw materials in the preheating device, and the water after heat exchange flows back into the water storage tank through the recovery pipe to be recycled.
本发明公开了一种低碱度硫铝酸盐水泥生产工艺，涉及水泥生产工艺技术领域，该低碱度硫铝酸盐水泥生产工艺，包括以下步骤：步骤一、原材料预处理，步骤二、生料均化，步骤三、高温煅烧，步骤四、冷却均化储存。本发明通过采用预热套筒、热能回收套筒、进水组件、蓄水箱、热水导出管以及回收管之间的配合，首先通过粉尘抽出组件携带大量热量和粉尘的气体抽出至热能回收套筒中，再通过进水组件将蓄水箱中储存的水抽入至热能回收套筒中，与携带热量的气体进行热交换，热交换后的温度较高的水经热水导出管流入至预热套筒中，为预热装置内部的原材料进行预热处理，热交换后的水经回收管流回至蓄水箱中，重复利用。
