Description

Technical Field

[0001] This utility model relates to the technical field of drainage gas extraction and water reinjection system equipment, and in particular to a novel simple reinjection tank. Background Technology

[0002] In the development of oil and gas fields, in order to cope with the situation where the water volume of gas wells is small in the later stage and the gas production is difficult to continue, active downhole water injection is adopted to increase the well fluid production volume, so as to ensure the normal operation of equipment and the production volume of well fluid, thereby maintaining the continuous production of coalbed methane (natural gas).

[0003] The new simplified reinjection tank mainly consists of a tank body, inlet, outlet, filter, level gauge, manhole or handhole, support structure, safety valve, pressure gauge, and auxiliary components. The tank body, the main structure, is used to hold the liquid and is typically cylindrical or square, made of corrosion-resistant material. The inlet is located at the top of the tank, and the outlet is at the bottom or side, both equipped with valves to control flow. The filter intercepts impurities, ensuring liquid cleanliness. The level gauge monitors the liquid level in real time, and the manhole or handhole facilitates operation. The support structure stabilizes the tank, and the safety valve and pressure gauge ensure safe operation. Auxiliary components ensure sealing and reliable connections.

[0004] Existing simplified reinjection tanks involve a wide variety of pipe and plate types, and the assembly process is complex and cumbersome, which directly leads to high production and manufacturing costs. In addition, the area of ​​the filter cotton chamber in the system is relatively small, which greatly limits its filtration capacity and cannot meet the filtration requirements of the reinjection water system in the actual operation of the drainage gas well. As a result, after the equipment has been running for a period of time, problems such as deterioration of filtration effect and accumulation of impurities are likely to occur, affecting the normal operation of the entire reinjection water system. It is impossible to provide stable and efficient reinjection water treatment support for the drainage gas well, which seriously restricts the production efficiency and economic benefits of the drainage gas well. Therefore, a new type of simplified reinjection tank is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a new type of simplified reinjection tank, which aims to improve the problems of high production material costs and complicated manufacturing processes in the production and manufacturing of reinjection water system tanks in the prior art, as well as the low filtration capacity of the reinjection tank.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A novel, simple reinjection tank includes a bottom support plate, a tank body fixedly connected to the top of the bottom support plate, an outlet pipe and an inlet pipe fixedly connected to the outer wall of the tank body, a primary filtration chamber and a secondary filtration chamber inside the tank body, a top cover on the top of the tank body, and a filter cotton placement chamber inside the tank body. The primary filtration chamber and the secondary filtration chamber are connected.

[0008] As a further description of the above technical solution:

[0009] A filter plate is slidably connected inside the tank, and the side wall of the filter plate is slidably connected to the inner wall of the filter cotton placement cavity.

[0010] As a further description of the above technical solution:

[0011] A handle is fixedly connected to the top of the filter plate, and a connecting component is provided at the bottom of the filter plate.

[0012] As a further description of the above technical solution:

[0013] The connecting component includes a connecting block, the top of which is fixedly connected to the bottom of the filter plate, and a hollow column is fixedly connected to the connecting block.

[0014] As a further description of the above technical solution:

[0015] The hollow column sidewall is slidably connected to the inside of the tank, and a rebound component is provided inside the hollow column.

[0016] As a further description of the above technical solution:

[0017] The rebound assembly includes a spring, the outer wall of which is disposed on the inner wall of the hollow column, and a retaining ball is fixedly connected to both ends of the spring, the outer wall of which is disposed inside the tank.

[0018] This utility model has the following beneficial effects:

[0019] 1. In this utility model, by designing and optimizing the tank's shape and internal filtration structure, it achieves both low production material costs and simple manufacturing processes, while improving the filtration performance of the reinjection water system, enhancing the quality of filtered water, and extending the maintenance cycle of the reinjection water system. The innovation in the external structure and process also increases the equipment's lifespan.

[0020] 2. In this utility model, by pulling the handle, the handle is forced to move the filter plate at the bottom. The movement of the filter plate causes the connecting block and hollow column at the bottom to move, and then the locking ball is moved to the inner wall of the hollow column, and the spring is retracted, achieving the effect of quick disassembly of the filter plate. This solves the problems of easy damage to the filter screen, inability to quickly disassemble it, troublesome replacement of the filter screen, and the need to spend time and effort to disassemble and assemble tank parts, increasing maintenance costs and equipment downtime. This improves the convenience of the new simple reinjection tank. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Reference Figures 1-3This utility model provides an embodiment of a novel simple reinjection tank, comprising a bottom support plate 1, a tank body 2 fixedly connected to the top of the bottom support plate 1, an outlet pipe 4 and an inlet pipe 5 fixedly connected to the outer wall of the tank body 2, a primary filtration chamber 3 and a secondary filtration chamber 8 inside the tank body 2, the secondary filtration chamber 8 and the primary filtration chamber 3 forming a countercurrent loop, and the double filter cotton intercepts pollutants to achieve an industrial-grade water purification effect, a top cover 7 is provided on the top of the tank body 2, a filter cotton placement chamber 6 is provided inside the tank body 2, and the primary filtration chamber 3 and the secondary filtration chamber 8 are connected.

[0030] Reference Figure 1 , Figure 4 and Figure 5 A filter plate 9 is slidably connected inside the tank body 2. The filter plate 9 slides up and down inside the tank body 2 via a connecting block 10 and a hollow column 11, fixing the filter plate 9 in the filter cotton placement cavity 6 to intercept suspended particles in the liquid. This achieves a primary filtration cavity 3 → secondary filtration cavity 8, improving the filtration accuracy to below 50μm and increasing the water purification efficiency by 40%. The side wall of the filter plate 9 is slidably connected to the inner wall of the filter cotton placement cavity 6. A handle 14 is fixedly connected to the top of the filter plate 9. The filter plate 9 is a 304 stainless steel stamped mesh plate with a 2mm aperture, used to support the filter cotton. It has strong corrosion resistance and is existing technology, so it will not be described in detail here. A connecting component is provided at the bottom of the filter plate 9, including a connecting block 10. When the filter plate 9 is pulled, the hollow column 11 moves... The moving ball 13 compresses the spring 12, causing the ball to disengage from the limiting groove of the tank 2, improving maintenance efficiency by 90% and reducing downtime. The top of the connecting block 10 is fixedly connected to the bottom of the filter plate 9. The connecting block 10 is fixedly connected to a hollow column 11. The side wall of the hollow column 11 is slidably connected to the inside of the tank 2. A rebound assembly is provided inside the hollow column 11. The rebound assembly includes a spring 12. The outer wall of the spring 12 is set on the inner wall of the hollow column 11. Both ends of the spring 12 are fixedly connected to the ball 13. The outer wall of the ball 13 is set inside the tank 2.

[0031] Working principle: When using the new simple reinjection tank, the liquid is first connected to the liquid discharge point through the water inlet pipe 5. Then the liquid will flow into the interior of the primary filter chamber 3. During this process, the primary filter chamber 3 is connected to the secondary filter chamber 8. The liquid will flow into the inner wall of the secondary filter chamber 8 through the filter cotton placement chamber 6. Then the liquid inside the secondary filter chamber 8 will flow from another filter cotton placement chamber 6 and then into the interior of another primary filter chamber 3. Finally, it will be discharged through the water outlet pipe 4. The production process is simple and more efficient. The degree of water filtration is improved by the reflux through the secondary filter chamber 8.

[0032] Then, when disassembling the filter plate 9, the connecting block 10 needs to be pulled first. The connecting block 10 is forced to move the bottom filter plate 9. Then, the filter plate 9 moves, causing the bottom connecting block 10 and the hollow column 11 to move. Next, during the movement of the hollow column 11, it is separated from the inside of the tank 2. During this process, the locking ball 13 is forced to move to the inner wall of the hollow column 11. During the process of the locking ball 13 being forced, the spring 12 on the side wall will be driven to retract, thereby achieving the effect of quickly disassembling the filter plate 9.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
