Problems solved by technology

[0003] At present, the liner method is mostly used in the completion of reinjection wells, that is, the screen is used to stick to the well wall to support the well wall and prevent large-volume rock formation debris from falling off. At the same time, screens are installed in the well to filter steam or liquid forms. However, due to the complex environment of geothermal water and a large amount of impurities, the screen pipe will be blocked after the recharge well is used for a long time. If it is not cleaned in time, the recharge well will be damaged. work efficiency dropped significantly
[0004] In the prior art, in order to prevent the clogging of the reinjection well, a filter mechanism is usually added on the inner wall of the screen to reduce the risk of clogging of the reinjection well, but this method is time-consuming and laborious, and cannot completely solve the problem of easy clogging of the reinjection well

Abstract

The invention discloses an anti-clogging device for a recharge well for a geothermal operation system, comprising a main screen pipe, a dredging assembly, a cleaning assembly and a controller. The main screen pipe is provided with screen holes, and the dredging assembly includes a mounting plate and a dredging rod. , The first motor, the second motor and the pushing mechanism, the first motor is located at the inner bottom of the main screen tube, the mounting plate is located on the output shaft of the first motor, the dredging and pushing mechanisms are all located inside the mounting plate, and the pushing mechanism is used to push The dredge rod goes in and out of the installation plate, the second motor is used to drive the installation plate to move in the main screen tube, the cleaning component is arranged at the lower end of the installation plate, and is used to clean the pollutants attached to the inner wall of the main screen tube. The motor and the second motor are electrically connected; the present invention has a reasonable structure design, can effectively reduce the risk of blockage of the recharge well, improve the utilization efficiency of geothermal resources, and is suitable for mass popularization.

Description

technical field [0001] The invention relates to the technical field of geothermal heating, in particular to an anti-clogging device for a recharge well used in a geothermal operation system. Background technique [0002] As a renewable energy source, although geothermal resources currently occupy a negligible position in the entire energy structure, compared with solar energy, wind energy and tidal energy, they have the highest grade and are the most realistic and feasible heat source. It will become an inexhaustible clean energy. Geothermal fluids that carry thermal energy are not inexhaustible, and over-exploitation will also lead to resource depletion; recharge is one of the main measures to achieve sustainable development and utilization of geothermal resources. In the geothermal utilization project with heating as the main purpose, the geothermal tail water after heat exchange can be used as the recharge water source. [0003] At present, the liner method is mostly us...
