Carbon sequestration method, ardealite product and preparation method of ardealite product
The invention discloses a carbon sequestration method, an ardealite product and a preparation method of the ardealite product. The carbon sequestration method comprises the following steps: converting captured carbon dioxide gas into water-soluble carbonic acid liquid under the action of certain temperature and pressure, directly adding the carbonic acid liquid into semi-hydrated ardealite under the action of continuous temperature and pressure, carrying out stirring at a high speed so as to allow when the semi-hydrated ardealite is reduced into dihydrate phosphogypsum in a hydration reaction process, the carbon sequestration is realized. carbon dioxide to be fixed in free water of ardealite in the form of carbonic acid when the semi-hydrated ardealite is reduced into dihydrate ardealite in a hydration reaction process, and directly preparing the ardealite product from the generated dihydrate ardealite so as to fix the carbon dioxide in the ardealite product in the form of liquid. According to the carbon sequestration method, carbon sequestration in three modes can be achieved in the ardealite product, recycling of the ardealite can be achieved, and the heat preservation, heat insulation and sound insulation functions of the ardealite product are further improved. The method is simple, controllable, low in cost, high in efficiency and large in carbon storage amount, the waste residue ardealite can be turned into the wealth, and good economic benefits and social benefits are achieved.
本发明公开了一种固碳方法及磷石膏制品及其制备方法。固碳方法为：将捕获的二氧化碳气体在一定温度和压力作用下转变为溶于水的碳酸液体，并在持续的温度和压力作用下，将碳酸液体直接加入半水磷石膏中，高速搅拌，使半水磷石膏在水化反应过程中还原成二水磷石膏时，将二氧化碳以碳酸形式固定在磷石膏的游离水中，再将生成的二水磷石膏直接制备成磷石膏制品，完成二氧化碳以液态形式固定在磷石膏制品中。本发明固碳方法不仅能在磷石膏制品中实现三种方式的碳封存，还能实现磷石膏的回收利用，并进一步提升磷石膏制品的保温、隔热、隔音功能。该方法简单可控，成本低，效率高，存碳量大，并能使废渣磷石膏变废为宝，具有良好的经济效益和社会效益。
