Concrete recycled aggregate, carbonization method and carbonization equipment of concrete recycled aggregate
The invention belongs to the technical field of building materials, and particularly relates to a concrete recycled aggregate, a carbonization method and carbonization equipment of the concrete recycled aggregate. The carbonization method comprises the following steps: carrying out crushing treatment on waste concrete to obtain concrete aggregate; preparing a carbonization reaction solution, and carrying out atomization treatment on the carbonization reaction solution to obtain atomized water drops; and mixing the concrete aggregate, the atomized water drops and the waste gas containing the carbon dioxide, carrying out gas-solid-liquid carbonization reaction, and separating and recycling a reaction product to obtain the carbonized concrete recycled aggregate. According to the semi-wet carbonization method based on the liquid-gas-solid reaction, the carbonization efficiency and degree are improved, the process difficulty is low, the cost is low, the operation is simple and convenient, and the method is environment-friendly and safe. A new path is provided for performance enhancement and industrial production of the concrete recycled aggregate, the treatment capacity of the solid waste is improved, meanwhile, the carbon capture efficiency of the solid waste is also improved, and great significance is provided for reducing carbon emission.
本申请属于建筑材料技术领域，尤其涉及一种混凝土再生骨料及碳化方法，以及一种混凝土再生骨料的碳化设备。其中，碳化方法包括步骤：对废弃混凝土进行破碎处理，得到混凝土骨料；配置碳化反应溶液，对碳化反应溶液进行雾化处理，得到雾化水珠；将混凝土骨料、雾化水珠和含二氧化碳的废气混合并进行气固液碳化反应，对反应产物进行分离回收，得到碳化后的混凝土再生骨料。基于液体‑气体‑固体反应的半湿法碳化方法，提高了碳化效率和程度，工艺难度低，成本低，操作简便，环保安全。不仅为混凝土再生骨料的性能增强及其工业化生产提供了新路径，提升固体废弃物的处理能力，同时也提升了固体废弃物的碳捕获效率，为减少碳排放提供了重大意义。
