Solid waste combined high-thermal-conductivity energy storage material as well as preparation method and application thereof
The invention discloses a solid waste combined high-thermal-conductivity energy storage material as well as a preparation method and application thereof. The solid waste combined high-thermal-conductivity energy storage material is prepared from the following raw materials in parts by mass: 2-3 parts of aggregate, 0.3-0.8 part of drilling mud and 0.8-1.2 parts of a curing agent, the aggregate comprises quartz sand and iron tailing sand. Quartz sand and iron tailing sand are soaked in water to be in a saturated state and then mixed and stirred to be uniform, and aggregate is obtained; uniformly mixing and stirring drilling mud and a curing agent to obtain curing agent slurry; and uniformly mixing and stirring the aggregate and the curing agent slurry, putting the mixture into a test mold, putting the test mold into a curing box for curing, and demolding to obtain the solid waste combined high-thermal-conductivity energy storage material. The backfill material can be used in the vertical well of the ground source heat pump. Quartz sand and waste iron tailing sand in mining are recycled and mixed with drilling mud and a curing agent to prepare the high-thermal-conductivity energy-storage backfill material for the first time, technical theoretical support is provided for design of the high-thermal-conductivity energy-storage material, the manufacturing cost is saved, the utilization rate of the waste iron tailings is increased, outward transportation of the drilling mud is reduced, and the economic benefit is increased. The ecological environment is protected.
本发明公开了一种固废组合的高导热储能材料及其制备方法和应用，由包含下列质量份数的原料制备得到：骨料2～3份、钻井泥浆0.3～0.8份、固化剂0.8～1.2份；骨料包含石英砂和铁尾矿砂。将石英砂和铁尾矿砂用水浸泡至饱和状态，然后混合搅拌均匀得到骨料；将钻井泥浆和固化剂混合搅拌均匀得到固化剂浆体；将骨料与固化剂浆体混合搅拌均匀后置于试模中，放入养护箱进行养护，脱模即得所述的固废组合的高导热储能材料。可用于在地源热泵竖直井中的回填材料。首次考虑将石英砂以及矿山开采中废弃的铁尾矿砂回收利用，与钻井泥浆、固化剂混合制备高导热储能回填材料，为高导热储能材料设计提供了技术理论支持，节省成本造价，提高了废弃铁尾矿的利用率，减少了钻井泥浆外运，生态环境得到保护。
