An underground self-operated forced vortex drainage and gas production device, the elastic body spring is connected to the elastic body; the lower end of the elastic body is provided with a turbine stator connected to the central pipe, and a pneumatic actuator is inserted inside the turbine stator; the pneumatic actuator is connected to the planetary wheel Inner meshing; the upper end of the planetary wheel is inserted into the connecting hole of the rotating arm; the inner conical surface of the rubber ring set on the upper end of the elastic body is attached to the frame; the rotating arm is connected to the swirling fluid inserted in the frame, Thrust ball bearings are embedded in the interference fit between them; when working, it first acts on the blade of the pneumatic actuator, when the pressure difference flowing through the stator blade and the blade of the pneumatic actuator meets the requirements for the device to spin, the pneumatic actuator starts to rotate, and the planetary Under the action of the gear speed-up mechanism, the rotating arm transmits a higher working speed for the swirling fluid; when the fluid flows out of the pneumatic execution end, a higher initial swirl intensity will be obtained, so that the gas-liquid separation and the two phases move upward in a spiral trajectory , to achieve laminar flow and better liquid-carrying effect.
Description
technical field [0001] The invention relates to the technical field of drainage and gas recovery of low-pressure and low-yield gas wells, in particular to an underground self-powered forced vortex drainage and gas recovery device. Background technique [0002] From the preliminary conceptual design of the forced vortex drainage gas recovery device to the present, the design ideas are becoming clearer. The devices designed in the past have the following deficiencies: (1) Compared with the straight cavity, the tapered cavity inside the device will increase the fluid acceleration and pressure drop loss; (2) The pneumatic actuator has a large load-bearing weight, resulting in a Large, the working conditions are not easy to meet. Contents of the invention [0003] In order to overcome the defects of the above-mentioned prior art and reduce the loss of pressure drop, the purpose of the present invention is to provide an underground self-supporting forced vortex drainage gas rec...
