Description

Technical Field

[0001] This utility model relates to the field of natural gas purification technology, and in particular to a natural gas impurity removal device. Background Technology

[0002] Natural gas typically carries various impurities during extraction and transportation, primarily including solid impurities (such as sand, mudstone, rust, and pipeline corrosion products) and liquid impurities (such as free water). These impurities not only reduce the combustion efficiency of natural gas, affecting its calorific value and stability, but can also cause wear and corrosion to gas transmission equipment. Before natural gas enters long-distance pipelines or is used at end-user locations, it must undergo rigorous purification treatment to remove harmful impurities, ensuring safe transportation and gas quality.

[0003] In existing technologies, natural gas filter cartridges can effectively remove impurities such as solid particles, liquid water, and oil from gas during operation, ensuring the stability of the gas transmission system and the safety of equipment. However, replacing traditional filter cartridges often requires system shutdown and a lengthy disassembly, replacement, and debugging process. This process not only leads to production interruptions and affects the continuity of gas supply, but also makes it difficult to respond quickly to sudden increases in impurities, potentially exacerbating pipeline blockage or equipment wear. Therefore, we propose a natural gas impurity removal device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a natural gas impurity removal device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A natural gas impurity removal device includes a purification box, a sleeve fixedly connected inside the purification box, a column slidably connected inside the sleeve, two circular through slots on the outer wall of the column, a sealing sleeve fixedly connected inside each of the two circular through slots, an end plate fixedly connected to the top of each of the two sealing sleeves, and multiple filter elements fixedly interconnected at the bottom of each end plate. A guide assembly is provided at the bottom of the purification box, a horizontal plate is fixedly connected inside the purification box, a hydraulic cylinder is fixedly connected to the outer wall of the horizontal plate, the outer wall of the output end of the hydraulic cylinder is fixedly connected to one end of the column, and an impurity discharge assembly is provided at the bottom of the purification box.

[0007] Preferably, the guide assembly includes an arc-shaped plate, and two connecting rods are fixedly connected inside the purification box. One end of each connecting rod is fixedly connected to the outer wall of the arc-shaped plate. By setting the guide assembly, impurities are prevented from being affected by the natural gas intake and thus from moving upward.

[0008] Preferably, the impurity removal component includes a drain pipe, one end of which is fixedly connected to the bottom of the purification box, and the other end of which is fixedly connected to a collection box. The top of the collection box is fixedly connected to the bottom of the purification box, thereby collecting solid and liquid impurities.

[0009] Preferably, the top of the purification box is fixedly connected to an air outlet pipe, and the outer wall of the purification box is fixedly connected to an air inlet pipe.

[0010] Preferably, electronic valves are fixedly installed on the outer walls of both the drain pipe and the air inlet pipe, and the opening and closing of the drain pipe and the air inlet pipe are controlled by the electronic valves.

[0011] Preferably, the bottom of the purification box is fixedly connected to two brackets, which support the purification box.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] This solution employs a dual-filter slot and hydraulic drive structure, enabling filter replacement without shutting down the system through the alternating switching of left and right filter groups. This completely solves the pain point of traditional technology requiring system shutdown for filter replacement, ensuring the continuity of natural gas supply and system stability. The dual-filter structure ensures that the system can maintain filtration efficiency even when there is a sudden increase in impurities, reducing the risk of pipeline blockage. Exposed old filter slots can be directly replaced while new filter groups are already in place and working, saving more time than traditional disassembly and replacement. Reducing downtime extends equipment life. Attached Figure Description

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Depend on Figures 1-4 As shown, a natural gas impurity removal device is disclosed, including a purification box 1. A sleeve 2 is fixedly connected inside the purification box 1, and a column 3 is slidably connected inside the sleeve 2. A sealing ring can be added to the contact surface between the sleeve 2 and the column 3 to improve the sealing performance. Two circular through grooves are opened on the outer wall of the column 3. A sealing sleeve 4 is fixedly connected inside the two circular through grooves. An end plate 5 is fixedly connected to the top of the two sealing sleeves 4. Multiple filter elements 6 are provided inside the two circular through grooves.

[0022] Multiple filter elements 6 are fixedly connected to the bottom of the end plate 5. An air outlet pipe 7 is fixedly connected to the top of the purification box 1. An air inlet pipe 8 is fixedly connected to the outer wall of the purification box 1. A horizontal plate is fixedly connected inside the purification box 1. A hydraulic cylinder 11 is fixedly connected to the outer wall of the horizontal plate. The horizontal plate supports the hydraulic cylinder 11. The hydraulic cylinder 11 is equipped with an existing pump station. The outer wall of the output end of the hydraulic cylinder 11 is fixedly connected to one end of the column 3. The hydraulic cylinder 11 drives the column 3 to move.

[0023] The bottom of the purification box 1 is provided with a guide assembly, which includes an arc plate 10. Two connecting rods 9 are fixedly connected inside the purification box 1. One end of each connecting rod 9 is fixedly connected to the outer wall of the arc plate 10. The two connecting rods 9 support the arc plate 10. The top of the arc plate 10 has a circular structure.

[0024] The bottom of the purification box 1 is equipped with a waste removal component, which includes a drain pipe 12. One end of the drain pipe 12 is fixedly connected to the bottom of the purification box 1, and the other end of the drain pipe 12 is fixedly connected to a collection box 14. The collection box 14 can be opened to clean the impurities inside periodically. The top of the collection box 14 is fixedly connected to the bottom of the purification box 1. Electronic valves 13 are fixedly installed on the outer walls of both the drain pipe 12 and the air inlet pipe 8. Two brackets 15 are fixedly connected to the bottom of the purification box 1.

[0025] Working principle: When purifying natural gas, natural gas is connected to the inlet pipe 8 and outlet pipe 7 through existing pipelines. Natural gas enters the purification box 1 through the inlet pipe 8 and is then filtered by multiple filter elements 6 in the circular through-slot on the right side of the column 3. Solid and liquid impurities are intercepted. The purified natural gas flows upward and is discharged from the outlet pipe 7. Impurities on the multiple filter elements 6 fall downward. The electronic valve 13 on the drain pipe 12 can be opened periodically (while the electronic valve 13 on the inlet pipe 8 is closed), allowing solid and liquid impurities to enter the collection box 14 along the drain pipe 12. When multiple filter elements 6 need to be replaced, the cylinder 11 rotates to move the column 3. The column 3 moves to the right, moving the two circular through-slots and the two end plates 5 inside. The movement distance is fixed, so that the left circular through-slot moves to the position of the right circular through-slot, and the right circular through-slot is fully exposed. The replacement does not affect the subsequent purification process of the natural gas.
