Description

一种耐酸急冷塔浇筑料及其制备方法及急冷塔
技术领域
本发明涉及耐腐蚀浇筑材料技术领域，尤其涉及一种耐酸急冷塔浇筑料及其制备方法及急冷塔。
背景技术
垃圾通过高温焚烧后，不但使垃圾得到无害化减量化，也使有毒有害物质以及二噁英得到有效处理。
二噁英在300度左右还能合成，而环境中的二噁英很难自然降解消除，它包括210种化合物，它的毒性十分大，是砒霜的900倍，有“世纪之毒”之称，万分之一甚至亿分之一克的二噁英就会给健康带来严的危害。因此需要进行快速冷却，急冷塔由此产生，但现有技术中的急冷塔浇筑材料制造成本高，耐腐蚀性低。
发明内容
本发明的目的是提供一种耐酸急冷塔浇筑料。
本发明还提供了一种耐酸急冷塔浇筑料的制备方法。
本发明还提供了一种浇筑有耐酸急冷塔浇筑料的急冷塔。
本发明的创新点在于本发明中的废高压电瓷瓶砂是在1450℃下高温烧结而成的、纯度较高，用在浇筑料内耐腐蚀性强、成本低。
为实现上述发明目的，本发明的技术方案是：
一种耐酸急冷塔浇筑料，包括以下质量分数的组分，废高压电瓷瓶砂72~81%，结合剂18~25%，添加剂1~3%。
进一步地，所述废高压电瓷瓶砂按重量份计包括粒度等级为0~0.063mm的2~5份、0.045~1mm的4~6份、1~3 mm的3~4份、3~5mm的3~4份、5~8mm的3~4份。
进一步地，所述结合剂为水玻璃。
进一步地，所述添加剂为氟硅酸钠。
一种耐酸急冷塔浇筑料的制备方法，包括以下步骤：
（1）按配方取料，将废高压电瓷瓶砂和添加剂预混，预混后加入水玻璃搅拌均匀即可按照需要浇筑成型。
一种浇筑有耐酸急冷塔浇筑料的急冷塔，包括壳体，壳体内壁依次设有OM涂料层和耐酸急冷塔浇筑料层。由于耐酸急冷塔浇筑料层之间有孔隙，再通过在壳体和耐酸急冷塔浇筑料层之间设置一层OM涂料层进一步防止从耐酸急冷塔浇筑料层孔隙之间透过的腐蚀料，进一步防止壳体腐蚀。
本发明的有益效果是 ：
1、本发明中的废高压电瓷瓶砂是在1450℃下高温烧结而成的、纯度较高、强度高，用在浇筑料内不渗水、耐腐蚀性强、成本低。
2、本发明中的浇筑有耐酸急冷塔浇筑料的急冷塔防腐蚀能力强。
附图说明
图1为浇筑有耐酸急冷塔浇筑料的急冷塔的结构示意图。
