Problems solved by technology
However, during the refilling process, due to the dissolved gas contained in the refilling water itself and the gas entrained in the flow process, when the conditions change, the gas exceeds its solubility limit and will be released from the solution to form bubbles. The existence of bubbles will cause The heat storage pore throat is blocked, and the dissolved oxygen O contained in the geothermal tail water 2 and carbon dioxide CO 2 It has a great corrosion effect on the recharge system and seriously affects the efficiency of the recharge process
The existing geothermal recharge water degassing technology is to use a degassing tank to degas before recharging, but the degassing technology of the degassing tank has certain shortcomings, and the degassing efficiency is low

The invention discloses a stirring ultrasonic degassing device for geothermal recharge water. The stirring ultrasonic degassing device comprises a shell, a water inlet is formed in the lower portion of the left side of the shell, a water outlet is formed in the upper portion of the right side of the shell, a liquid level meter is arranged on the portion, between the water inlet and the water outlet, of the side wall of the shell in the vertical direction, and a stirrer is installed in the center of the top of the shell. A stirring shaft of the stirrer penetrates through the top wall of the shell in the vertical direction and is arranged in the shell, stirring blades are installed at the bottom and in the middle of the stirring shaft respectively, and the stirring blades are three-blade push type stirring blades. An automatic exhaust valve, a sight glass and a temperature measuring system are installed on the top wall of the shell, a plurality of baffles arranged in the vertical direction are installed in the shell, an ultrasonic transducer is installed on the bottom wall of the shell, and the stirring shaft can be disassembled into three sections from the stirring blades. By adopting the device, the liquid is uniformly mixed, the ultrasonic irradiation is more uniform, and the degassing efficiency is improved.
Description
technical field [0001] The invention relates to a degassing device, in particular to a stirring ultrasonic degassing device for geothermal recharge water. Background technique [0002] Geothermal tail water recharge is the most favorable technology to maintain geothermal production capacity and protect the environment. With the development of geothermal energy, problems such as the decline of heat storage capacity and environmental pollution have appeared one after another. In order to improve this basic situation, a recharge test of geothermal tail water was carried out. However, during the refilling process, due to the dissolved gas contained in the refilling water itself and the gas entrained in the flow process, when the conditions change, the gas exceeds its solubility limit and will be released from the solution to form bubbles. The existence of bubbles will cause The heat storage pore throat is blocked, and the dissolved oxygen O contained in the geothermal tail wat...
