AI Technical Summary
Existing reinjection wells suffer from problems such as trace amounts of silt, biological and chemical blockages in groundwater geothermal utilization. In particular, the outer wall of the filter pipe is not thoroughly cleaned, resulting in a short blockage cycle and rapid bacterial growth, which is difficult to effectively solve with existing cleaning methods.
Pure water or chemicals are delivered to the gravel layer through drainage pipes distributed in the gravel layer. The drainage pipes are connected to the filter pipes through fixed supports to achieve cleaning from the outside in. The improved fixed supports serve as channels for delivering detergent, simplifying the structure and stabilizing the filter pipes.
This method achieves thorough cleaning of the outer wall of the filter pipe, extends the cleaning cycle, prevents re-clogging, and improves the cleaning effect and equipment stability.

Pure water can also be directly output for flushing from the outside of the filter pipe, therefore, a pressurizing device or similar device needs to be arranged on the pipeline of the washing pipe to make it have sufficient pressure. It needs to be noted that the outlet of the liquid discharge pipe is generally arranged towards the filter pipe and cannot be arranged in the opposite direction of the filter pipe, which has good effect on cleaning of silt blockage. Of course, the washing pipe, the liquid discharge pipe and other related pipelines of the utility model can be adjusted in diameter according to related requirements, Figure 2 The pipeline in the figure is only used for structure display.

The gate valve well chamber 6 is surrounded by clay balls 9 for layered sealing. The sealing is to ensure that there is no leakage, so other sealing structures can also be used as long as they meet the design requirements. The liquid injection equipment is arranged in the gate valve well chamber 6. The liquid injection equipment is a pipeline liquid adding device with multiple storage tanks, which can store different materials. It should be noted that the pipeline should have a cleaning function to prevent various washing agents from remaining in the washing pipe 5 and causing corrosion of the pipeline.
