The invention relates to the sandstone heat storage industry, and particularly discloses an anti-blocking filtering structure for sandstone heat storage recharge. The filtering structure comprises a first barrel, a flow guide driving device, a first filtering piece, a dirt removing device connected with the first filtering piece, a second-stage filtering device fixedly connected with the first barrel, an impurity guiding and conveying device, and a child-mother cylinder filtering device; the dirt removing device comprises a linkage adjusting device connected with the first barrel in a sliding mode; and the child-mother cylinder filtering device is in sliding connection with the side, away from the linkage adjusting device, of the first filtering piece. The child-mother cylinder filtering device is matched with the second-stage filtering device in the filtering structure, efficient filtering and purifying of a water body are achieved, backwater blockage is prevented, and meanwhile under driving of potential energy of the water body and high-temperature gas, the internal linkage adjusting device and the impurity guiding and conveying device are driven to operate, and automatic cleaning and guiding and conveying of impurities are achieved.
Description
technical field [0001] The invention relates to the sandstone heat storage industry, in particular to an anti-clogging filter structure for sandstone heat storage recharge. Background technique [0002] Sandstone heat storage is widely distributed in sedimentary basins in my country, and the degree of development and utilization is high, but the low recharge rate has become the bottleneck of its sustainable development. Studies have shown that the main reason for the difficulty of recharge is the blockage around the wellbore, which is related to the blockage of suspended matter, chemical precipitation and air bubbles caused by the mineral composition of the reservoir, diagenetic effect, and water-rock interaction during the recharge process. [0003] The existing sandstone heat storage and recharge structure has many impurities and other mixtures during the heat extraction process, which is easy to cause blockage, reducing the heat extraction effect and heat conversion effic...
