Description

Technical Field

[0001] This invention relates to the field of downhole compressed air system technology, and in particular to a gas-water separation device. Background Technology

[0002] Currently, most underground compressed air pipelines directly supply air to roadways and working faces. However, compressed air often contains water vapor, dust, rust, and other impurities. These impurities not only adhere to the internal components of air supply equipment (such as pneumatic tools and pneumatic valve groups), leading to increased equipment wear and higher failure rates, but also form scale on the inner walls of pipelines, reducing the flow cross-section and affecting the air supply pressure and flow rate. Although some mines have adopted simple air-water separation devices, existing devices often lack targeted condensation structure designs, resulting in low water-air separation efficiency and easy clogging of filter components. This requires frequent manual disassembly and cleaning, which not only increases operation and maintenance costs but may also affect normal underground operations due to downtime, making it difficult to meet the long-term stable air supply needs of underground operations. Summary of the Invention

[0003] The technical problem to be solved by the embodiments of the present invention is the low water-gas condensation efficiency of the gas-water separation device in the existing downhole compressed air system.

[0004] To address the aforementioned problems, this invention discloses a gas-water separation device. By optimizing the pipe layout of the separator, the gas-water separation efficiency is improved.

[0005] This invention provides a gas-water separation device, which includes a separator and a filter screen. The separator includes an inlet pipe, an outlet pipe, a front condenser pipe, and a rear condenser pipe. One end of the front condenser pipe is connected to the inlet pipe, and the other end is connected to the rear condenser pipe. The outlet pipe is connected to the rear condenser pipe, and the axes of the inlet pipe and the outlet pipe are at the same horizontal level. A filter channel is formed between the inner wall of the rear condenser pipe and the outer wall of the front condenser pipe, and the filter screen is disposed in the filter channel.

[0006] A further technical solution includes a first baffle, which is disposed on the inner wall of the rear condensing pipe and located below the front condensing pipe, and the first baffle is arranged in an inclined state.

[0007] A further technical solution includes a second baffle, which is disposed on the inner wall of the post-condensation pipe and located below the filter screen, and the second baffle is arranged in an inclined state.

[0008] A further technical solution is that the air inlet pipe, the front condenser pipe, the rear condenser pipe, and the air outlet pipe are integrally formed.

[0009] A further technical solution is that the bottom of the post-condensation pipe is a downwardly convex arc-shaped structure, and the lowest end of the arc-shaped structure is provided with a narrowing opening extending in the vertical direction. The inner diameter of the narrowing opening is smaller than the inner diameter of the main body of the post-condensation pipe.

[0010] A further technical solution is that a solenoid valve is provided at the bottom of the narrowed opening.

[0011] A further technical solution includes a water level monitor; the water level monitor is located on the bottom inner wall of the post-condensation pipe, and the signal output terminal of the water level monitor has a wire for connecting to an external control unit.

[0012] A further technical solution includes a controller, which is electrically connected to both the solenoid valve and the water level monitor.

[0013] A further technical solution is that the controller integrates a timing module, which is preset with time interval parameters for triggering the opening of the solenoid valve.

[0014] A further technical solution is that the angle between the first baffle and the inner wall of the post-condensation pipe is in the range of 30° to 45°.

[0015] Compared with the prior art, the technical effects achieved by the embodiments of the present invention include: To improve water-air separation efficiency, the design of connecting the front and rear condenser pipes and the airflow guiding effect of the inclined baffles are used to extend the residence time of compressed air in the device, promote the full condensation of water-air, and improve the condensation efficiency compared with the existing device. To ensure continuous filtration, the combination of the filter channel and the arc-shaped bottom narrowing opening guides impurities to gather with the condensate water towards the narrowing opening, reducing filter screen clogging. Combined with the automatic sewage discharge and backwashing effect of the solenoid valve, the cleaning cycle of the filter components is extended. Reduced operation and maintenance costs: The integrated molding structure reduces the risk of leakage at pipe connections. Automated monitoring and timed sewage discharge functions eliminate the need for manual operation, reducing the frequency of equipment maintenance and significantly improving the overall operational stability of the downhole compressed air system.

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Similar component reference numerals in the drawings represent similar components. Obviously, the embodiments described below are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] It should be understood that, when used in this specification and the appended claims, the terms "comprising" and "including" indicate the presence of the described features, integrals, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or collections thereof.

[0021] It should also be understood that the terminology used in this specification of embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to limit the embodiments of the invention. As used in this specification of embodiments of the invention and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0022] See Figures 1-2 This invention provides a gas-water separation device. The device includes a separator 1 and a filter screen 2. The separator 1 includes an inlet pipe 11, an outlet pipe 13, a front condenser pipe 12, and a rear condenser pipe. One end of the front condenser pipe 12 is connected to the inlet pipe 11, and the other end is connected to the rear condenser pipe 14. The outlet pipe 13 is connected to the rear condenser pipe 14, and the axes of the inlet pipe 11 and the outlet pipe 13 are at the same horizontal level. A filter channel is formed between the inner wall of the rear condenser pipe and the outer wall of the front condenser pipe 12, and the filter screen 2 is disposed within the filter channel. Specific descriptions of each component are as follows: In this embodiment, the separator 1 is the main supporting structure of the device, including an inlet pipe 11 (for connecting to the underground compressed air pipeline), an outlet pipe 13 (for outputting clean compressed air to the roadway / working face), a front condenser pipe 12 (primary condenser section), and a rear condenser pipe (secondary condenser and filtration section); the filter screen 2 is made of 304 stainless steel woven mesh (mesh count 80-120 mesh), and is located in the annular filtration channel formed by the inner wall of the rear condenser pipe and the outer wall of the front condenser pipe 12, for intercepting impurities in the compressed air; One end of the front condenser pipe 12 is welded to the intake pipe 11 (or integrally formed), and the other end is located inside the rear condenser pipe and connected to the rear condenser pipe 14; the exhaust pipe 13 is connected to the side wall of the rear condenser pipe, and the axes of the intake pipe 11 and the exhaust pipe 13 are at the same horizontal height (to ensure that the airflow enters smoothly and avoids airflow disturbance caused by height difference).

[0023] Through the connecting path of "intake pipe 11 - front condenser pipe 12 - rear condenser pipe - outlet pipe 13", compressed air enters from the intake pipe 11, first undergoes preliminary expansion and pressure reduction through the front condenser pipe 12 (promoting water vapor condensation), then enters the filter channel of the rear condenser pipe, where impurities are intercepted by the filter screen 2, and finally outputs from the outlet pipe 13. The intake pipe 11 and outlet pipe 13 at the same horizontal height avoid eddies caused by the height difference in airflow, ensuring airflow stability. At the same time, the annular design of the filter channel increases the filter area and reduces airflow resistance. Compared with the traditional straight cylindrical filter structure, the airflow resistance is reduced and the filtration efficiency is improved.

[0024] See also Figures 1-2 In this embodiment, a first baffle 41 is also included. The first baffle 41 is disposed on the inner wall of the rear condensing pipe and located below the front condensing pipe 12. The first baffle 41 is arranged in an inclined state.

[0025] Specifically, the first baffle 41 is fixed to the inner wall of the rear condensing pipe, for example by spot welding, and is located directly below the front condensing pipe 12, arranged in an inclined state. The first baffle 41 is not connected to the outer wall of the front condensing pipe 12, and the connection between the front condensing pipe 12 and the rear condensing pipe 14 is maintained.

[0026] The first baffle 41 is tilted in a direction where "the end fixed to the rear condenser pipe is higher and the unfixed end is lower", and the tilt angle between it and the inner wall of the rear condenser pipe is set to 35°; the edge of the first baffle 41 is polished to avoid residual impurities.

[0027] When compressed air enters the rear condenser pipe from the front condenser pipe 12, the first baffle 41 can block the airflow from flowing directly downwards, forcing the airflow to detour along the inclined direction of the baffle, prolonging the residence time of the airflow in the device. At the same time, when the airflow comes into contact with the baffle, temperature exchange occurs, further promoting water vapor condensation. In addition, the inclined structure can guide the condensate along the baffle to the bottom of the rear condenser pipe, avoiding the condensate from remaining on the inner wall of the pipe and reducing the adhesion of impurities.

[0028] Furthermore, it also includes a second baffle 42, which is disposed on the inner wall of the post-condensation pipe and located below the filter screen 2, and the second baffle 42 is arranged in an inclined state.

[0029] Specifically, the second baffle 42 is fixed to the inner wall of the rear condenser pipe and is located directly below the filter screen 2. The second baffle 42 is tilted in the direction of "the end fixed to the rear condenser pipe is higher and the unfixed end is lower", and the tilt angle with the inner wall of the rear condenser pipe is set to 40°. The second baffle 42 and the first baffle 41 form a double-flow guiding structure with opposite inclinations. On the one hand, it can further extend the airflow path, allowing the water vapor that has not been fully condensed to come into contact with the baffle again, thus improving the condensation efficiency compared to the single baffle structure. On the other hand, it can intercept impurities that fall off the filter screen 2, preventing impurities from directly impacting the bottom of the pipe, and guiding impurities to gather at the bottom with the condensate, reducing the dispersion and accumulation of impurities in the pipe and reducing the risk of blockage at the drain outlet.

[0030] Furthermore, the air inlet pipe 11, the front condenser pipe 12, the rear condenser pipe, and the air outlet pipe 13 are integrally formed structures.

[0031] Specifically, it is manufactured in one piece through a casting process to achieve no welding seams, and the inner wall of each pipe connection point is a smoothly transitioning arc shape.

[0032] Furthermore, the bottom of the post-condensation pipe is a downwardly convex arc-shaped structure, and the lowest end of the arc-shaped structure is provided with a narrowing opening extending in the vertical direction. The inner diameter of the narrowing opening is smaller than the inner diameter of the main body of the post-condensation pipe.

[0033] Specifically, the arc length of the arc-shaped bottom covers the entire circumference of the bottom of the condensate pipe, ensuring that condensate can converge at the lowest end. The inner wall of the narrowed opening smoothly transitions with the inner wall of the arc-shaped bottom to avoid impurities from accumulating. The outer wall of the narrowed opening is provided with external threads for connecting the drain components.

[0034] The raised structure at the arc-shaped bottom utilizes gravity to automatically collect condensate at the lowest point, preventing condensate from dispersing and stagnating at the bottom. The narrow inner diameter design of the opening increases the flow rate of condensate, carrying impurities out quickly and reducing the deposition of impurities at the bottom. At the same time, it provides a compact connection structure for the subsequent installation of the drain valve, saving overall space of the device.

[0035] Furthermore, a solenoid valve 3 is provided at the bottom end of the narrowed opening.

[0036] Specifically, the outlet of solenoid valve 3 is connected to a sewage pipe, which extends to the underground drainage system.

[0037] The solenoid valve 3 replaces the traditional manual valve, realizing automated control of sewage discharge without the need for on-site manual operation, thus solving the safety hazards and efficiency problems of manual sewage discharge in the well. The normally closed design can ensure the sealing of the device in the non-sewage discharge state, avoiding compressed air leakage, and at the same time, it is compatible with subsequent automated control components, laying the foundation for realizing automated sewage discharge.

[0038] In one embodiment, when the solenoid valve 3 is opened, the compressed air in the separator will discharge the deposited condensate and impurities through the solenoid valve 3, and the compressed air in the air outlet pipe 13 will backwash the filter screen 2 to remove the impurities adhering to the filter screen 2 and ensure that the filter screen 2 is unobstructed.

[0039] Furthermore, it also includes a water level monitor 5; the water level monitor 5 is located on the bottom inner wall of the post-condensation pipe, and the signal output terminal of the water level monitor 5 has a wire for connecting to an external control unit.

[0040] Specifically, the probe end of the level sensor faces the curved bottom to ensure direct contact with the condensate.

[0041] The water level monitor 5 can monitor the condensate water level at the bottom of the condensate pipe in real time, replacing manual observation and solving the problem of "inability to judge the amount of condensate water accumulation". The accurate liquid level measurement can ensure that the sewage discharge action is triggered only when the condensate water reaches the set threshold, such as when the water level is 20mm higher than the top of the narrowing opening. This avoids the waste of compressed air caused by frequent sewage discharge, reduces compressed air loss, and prevents the condensate water level from flowing back into the filter channel and affecting the filtration effect.

[0042] Furthermore, it also includes a controller, which is electrically connected to the solenoid valve 3 and the water level monitor 5 respectively.

[0043] Specifically, the controller has preset water level thresholds, such as "high water level 20mm, low water level 5mm". When the water level monitor 5 detects that the water level reaches 20mm, the controller outputs a signal to control the solenoid valve 3 to open and perform sewage discharge. When the water level drops to 5mm, the controller outputs a signal to control the solenoid valve 3 to close.

[0044] In one embodiment, the water level monitor 5 is a water level controller. When the condensate accumulates to a certain water level, the water level controller sends a signal to the controller.

[0045] Furthermore, the controller integrates a timing module, which is preset with time interval parameters for triggering the opening of the solenoid valve 3.

[0046] Specifically, the timing module is integrated inside the controller, which can preset the time interval parameters for the opening of the solenoid valve 3, such as 8 hours or 12 hours, and can also set the duration of a single opening, such as 30 seconds or 60 seconds.

[0047] The timing module solves the problem of blind spots in sewage discharge in scenarios with "low water and air but high impurities". Traditional devices rely solely on water level triggering, which can easily lead to the accumulation and blockage of impurities. By using timed sewage discharge, the attached impurities on filter screen 2 can be cleaned regularly, ensuring unobstructed filtration channels. The switchable cycle parameters adapt to different underground working conditions, such as using a 12-hour cycle in dry seasons and an 8-hour cycle in humid seasons, further improving the operational stability of the device.

[0048] Furthermore, the angle between the first baffle 41 and the inner wall of the post-condensation pipe is in the range of 30° to 45°.

[0049] Specifically, the angle between the first baffle 41 and the inner wall of the post-condensation pipe is in the range of 30° to 45°. The angle can be designed according to the airflow velocity of the underground compressed air system. The higher the airflow velocity, the smaller the angle value, and the lower the airflow velocity, the larger the angle value.

[0050] The angle range of 30° to 45° is the optimal balance range between "airflow resistance" and "condensation efficiency": when the angle is less than 30°, the baffle has a weak blocking effect on the airflow and the condensation efficiency decreases; when the angle is greater than 45°, the airflow resistance increases significantly, which can easily lead to the pressure difference between the inlet and outlet of the device exceeding the standard.
