Ground source heat pump granular backfill material, preparation method and backfill method
The invention is applicable to the technical field of ground source heat pump backfilling, and provides a ground source heat pump granular backfilling material which comprises the following raw materials in percentage by weight: 60-65% of quartz powder, 15-18% of waste steel slag, 1-1.2% of graphite, 0.4-0.5% of adhesive and the balance of bentonite. The invention also provides a preparation method of the ground source heat pump granular backfill material. The invention further provides a backfilling method of the ground source heat pump granular backfilling material. The backfill material is added into the industrial solid waste, high performance and low cost are achieved, natural resources are saved, the heat exchange requirement of the ground source heat pump backfill material can be met, the accuracy and uniformity of the material ratio can be guaranteed, the granular backfill material is easy to store, convenient to transport and construct, high in backfill compactness and free of backfill gaps, and the backfill material is suitable for large-scale production. And in combination with the properties of the granular backfill material, a reverse circulation backfill process is invented in a matched manner, so that the backfill process is more efficient and convenient.
本发明适用于地源热泵回填技术领域，提供了一种地源热泵颗粒状回填材料，包括以下重量百分比的原料：石英粉60％‑65％、废钢渣15％‑18％、石墨1％‑1.2％、粘接剂0.4％‑0.5％，膨润土余量补足至100％。本发明还提供了一种地源热泵颗粒状回填材料的制备方法。本发明还提供了一种地源热泵颗粒状回填材料的回填方法。本发明使用工业固废加入回填材料，高性能、低成本，节约了自然资源的利用，不仅能满足地源热泵回填材料的换热需求，材料配比的准确性和均匀性也能得到保证，且颗粒状回填材料易于存放、方便运输、施工便捷，回填密实度高，回填无空隙，且环境友好，结合颗粒状回填料的性质，配套发明了反循环的回填工艺，使回填过程更高效便捷。
