Description

Safe flow guide control device of self-blowing geothermal well

Technical Field

The utility model belongs to the technical field of the geothermal well device that spouts, specifically indicate a safe water conservancy diversion controlling means of geothermal well that spouts.

Background

At present, geothermal energy resources are used as renewable and reusable clean energy resources, have very wide development and application prospects, and are increasingly attracted by general attention and attention of the human society. The requirement for developing clean energy is increasing day by day, and the clean energy, the health care resources and the water resources have important significance and wide development prospect.

The high-temperature geothermal resources in the hydrothermal geothermal resources generally have the characteristics of high pressure and high temperature, namely, the self-blowing geothermal well, and due to the fact that the geothermal well is self-blown in temperature and high in temperature, maintenance personnel cannot approach the self-blowing geothermal well to conduct maintenance, pump descending and other operations, and the self-blowing geothermal well is out of control in serious conditions, and great potential safety hazards exist.

Disclosure of Invention

For solving the above-mentioned current difficult problem, the utility model provides a security height, the result of use is more stable, simple structure, and simple to operate's the safe water conservancy diversion controlling means of flowing from geothermal well.

The utility model adopts the following technical scheme: the utility model discloses safe water conservancy diversion controlling means of flowing geothermal well, including the cross shell, the cross shell is including being first pipeline, second pipeline, third pipeline and the fourth pipeline that the cross shell is outer located at intervals such as circumference form, be equipped with the preventer on the first pipeline, be equipped with air relief valve and temperature sensor on the second pipeline, air relief valve locates second pipeline tail end, inside temperature sensor located the second pipeline, be equipped with second valve and mud interface on the third pipeline, the third pipeline tail end is located to the mud interface, be equipped with first valve and geothermal water interface on the fourth pipeline, the fourth pipeline tail end is located to the geothermal water interface.

Further, the first pipeline is connected with a geothermal well pipeline.

Further, the automatic exhaust valve controls the exhaust amount of gas in the pipeline.

Further, the first valve controls geothermal water flow and the second valve controls mud flow.

Furthermore, a sight window is arranged on the blowout preventer.

Furthermore, the outer wall of the four-way shell is provided with a controller, the temperature sensor is connected with the controller, and the controller is connected with the automatic exhaust valve.

Adopt above-mentioned step the utility model discloses the beneficial effect who gains as follows: this flowing geothermal well not only installs preventer at the geothermal well head, has still installed automatic checkout gear, can prevent that the liquid in the flowing geothermal well from causing liquid blowout scheduling problem in the well because of the inside high temperature of pipeline, the cracked phenomenon appears, avoids causing the equipment to damage and lead to the fact the security threat to the staff, and the device has improved the security, makes the utilization ratio of the energy higher, and the safety problem that significantly reduces.

Drawings

Fig. 1 is a schematic structural view of the safe flow guiding control device of the self-blowing geothermal well of the present invention.

The device comprises a four-way shell, a first pipeline, a second pipeline, a third pipeline, a fourth pipeline, an automatic exhaust valve, a temperature sensor, a first valve, a second valve, a filter screen, a slurry interface, a geothermal water interface, a blowout preventer, a controller, a second pipeline, a third pipeline, a fourth valve, a fourth.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1, the utility model discloses safe water conservancy diversion controlling means of flowing geothermal well, including cross shell 1, cross shell 1 locates first pipeline 2, second pipeline 3, third pipeline 4 and fourth pipeline 5 outside cross shell 1 including being the interval such as circumference form, be equipped with preventer 13 on first pipeline 2, be equipped with air relief valve 6 and temperature sensor 7 on the second pipeline 3, air relief valve 6 locates the 3 tail ends of second pipeline, temperature sensor 7 locates inside the 3 second pipeline, be equipped with second valve 9 and mud interface 11 on the third pipeline 4, mud interface 11 locates the 4 tail ends of third pipeline, be equipped with first valve 8 and geothermal water interface 12 on the fourth pipeline 5, geothermal water interface 12 locates the 5 tail ends of fourth pipeline.

The first pipeline 2 is connected with a geothermal well pipeline, the automatic exhaust valve 6 controls the discharge amount of gas in the pipeline, the first valve 8 controls the flow of geothermal water, the second valve 9 controls the flow of slurry, the blowout preventer 13 is provided with a viewing window, the outer wall of the four-way shell 1 is provided with a controller 14, the temperature sensor 7 is connected with the controller 14, and the controller 14 is connected with the automatic exhaust valve 6.

When the safe diversion control device is used, before the safe diversion control device of the self-blowing geothermal well is used, the first pipeline 2 is connected with a geothermal well mouth, after the installation is finished, the controller 14, the blowout preventer 13 and the second valve 9 are opened, so that liquid in the self-blowing geothermal well enters the four-way shell 1 through the blowout preventer 13, then enters the third pipeline 4 and flows out through the second valve 9, after several minutes, slurry flows out, the position of a window is checked to see whether geothermal water is clear, if the geothermal water in the window is clear, the second valve 9 is closed, the first valve 8 is opened, the geothermal water flows into the fourth pipeline 5 through the filter screen 10, so that the geothermal water flows out through the geothermal water interface 12, if the pressure value in the pipeline is too large, the temperature sensor 7 sends a signal to the controller 14, the controller 14 controls the automatic exhaust valve 6 to be opened, so that high-pressure gas in the automatic blowing geothermal well is exhausted, and the liquid in the self-blowing geothermal well can be prevented from being too high temperature due, the phenomenon of breakage occurs, liquid in the well is sprayed out, equipment is damaged, and safety threats are caused to workers.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all of which utilize the equivalent structure or equivalent flow transformation made by the content of the specification of the present invention, or directly or indirectly applied to other related technical fields, all included in the same way in the patent protection scope of the present invention.
