Production method of multipurpose ardealite product
The invention provides a production method of a multipurpose ardealite product, which comprises the following steps: mixing a liquid low-boiling-point organic matter with water-containing ardealite, replacing moisture of the ardealite, then carrying out solid-liquid separation treatment to obtain a solid ardealite raw material, and feeding the solid ardealite raw material to a gypsum heater; part of the gypsum material in the gypsum heater is fed into a light heating energy storage tank to be naturally heated by sunlight and stored; feeding part of the gypsum material in the light heating energy storage tank into a fluidized bed dryer to prepare coarse-fraction gypsum and fine-fraction gypsum; the residual gypsum material in the gypsum heater and the residual gypsum material in the light heating energy storage tank are mixed and then fed into a rotary kiln to be prepared into cement clinker and tail gas rich in sulfur dioxide for sulfuric acid production. The ardealite is preheated by solar energy, and waste gas in the process enters the rotary kiln for combustion, so that the energy consumption in the production process is reduced; the production processes of all the products are associated, it is guaranteed that the production processes of all the products are not interrupted, the material distribution proportion is adjusted according to the actual situation, and the continuity and adjustability of the production processes are improved.
本发明提供一种多用途磷石膏制品的生产方法，包括：利用液体低沸点有机物与含水磷石膏混合并置换出磷石膏的水份，后进行固液分离处理，得固体磷石膏原料，送至石膏加热器；将石膏加热器中的部分石膏料送入光加热储能槽由阳光进行自然加热并储存；将光加热储能槽中的部分石膏料送入流化床干燥器，制成粗粒级石膏和细粒级石膏；将石膏加热器中的剩余石膏料和光加热储能槽中的剩余石膏料混合后送入回转窑制成水泥熟料和富含二氧化硫的尾气用于硫酸生产。太阳能对磷石膏进行预加热，过程废气进入回转窑燃烧，降低了生产过程的能耗；各产品生产过程关联，保证各产品生产过程不中断，并根据实际情况调节物料分流比例，提高了生产过程的连续性和可调节性。
