[0002] Thermal power generation has long dominated my country's power supply due to its mature technology and stable operation. Natural gas power generation, on the other hand, is cleaner, more efficient, and more flexible, better meeting the electricity needs of economic and social development. Before natural gas combustion power generation, natural gas needs to be pre-treated by natural gas purification devices to ensure the quality and safety of natural gas, while improving energy utilization efficiency and reducing energy consumption.

[0003] Existing natural gas power generation purification units use bag filters to treat particulate matter and other impurities in natural gas. However, after these filters are removed, the filter bags need to be manually opened for cleaning and replacement. This process is complex, increases downtime, and affects work efficiency. In addition, existing natural gas power generation purification units usually separate the bag filter and cyclone separator into two separate units, which increases the floor space and operating costs.

[0004] Therefore, it is necessary to provide a new energy-saving and emission-reducing purification device for natural gas power generation to solve the above-mentioned technical problems. Utility Model Content

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] Please see Figures 1 to 4 An energy-saving and consumption-reducing purification device for natural gas power generation, comprising: a cylinder 1, an air inlet pipe 2 fixedly connected to one side of the cylinder 1, an air outlet pipe 3 fixedly connected to the top of the cylinder 1, a spiral air inlet rail 4 fixedly connected inside the cylinder 1, a cone 5 fixedly connected to the bottom of the cylinder 1, a discharge port 6 provided at the bottom of the cone 5, a dust collection seat 7 fixedly connected to the bottom of the discharge port 6, a filter seat 8 fixedly connected to the top of the cylinder 1, a baffle 9 fixedly connected to the inner wall of the filter seat 8, the filter seat 8 being divided into an upper clean air chamber 10 and a lower filter chamber 11 by the baffle 9, a cover plate 12 installed on the top of the filter seat 8, a rotating assembly for controlling the cover plate 12 installed on the top of the filter seat 8, a bypass guide rail 61 opened on one side of the cylinder 1, and a sealing ring 71 fixedly connected to the inner wall of the filter seat 8;

[0027] It should be noted that: the spiral air intake rail 4 is oriented downwards, causing the natural gas to move downwards in a spiral shape inside the cylinder 1; the baffle 9 prevents the natural gas from directly entering the clean air chamber 10; the bypass guide rail 61 is designed to introduce part of the airflow from the top of the cyclone filter to the bottom, preventing residual impurities from accumulating at the top of the filter and excessively damaging the inner wall of the cylinder 1; and the sealing ring 71 provides a good sealing effect to prevent natural gas leakage.

[0028] Please see Figure 3 and Figure 4The rotating assembly includes: a drive motor 21, a threaded rod 22, a sleeve 23, a slider 24, a pusher 25, a lifting cylinder 26, and a connecting rod 27. The sleeve 23 is fixedly connected to the outer wall of the filter seat 8. One end of the sleeve 23 has an L-shaped groove 28. The lifting cylinder 26 is slidably connected to the outer wall of the sleeve 23. The bottom of the lifting cylinder 26 is fixedly connected to the pusher 25, which slides in the L-shaped groove 28. The drive motor 21 is fixedly connected to the outer side of the filter seat 8. The output end of the drive motor 21 is fixedly connected to the threaded rod 22, which rotates in the sleeve 23. One end of the threaded rod 22 is threadedly connected to the slider 24, which is fixedly connected to the pusher 25. The lifting cylinder 26 is fixedly connected to one side of the connecting rod 27, which is fixedly connected to the cover plate 12. The stroke of the L-shaped groove 28 parallel to the filter seat 8 is greater than half of the outer circumference of the sleeve 23.

[0029] It should be noted that: the L-shaped groove 28 passes through the sleeve 23, and one side of the push block 25 passes through the L-shaped groove 28 and is fixedly connected to the slider 24. The stroke of the part of the L-shaped groove 28 parallel to the filter seat 8 is greater than half of the outer circumference of the sleeve 23, so that the rotation angle of the push block 25 with the axis of the sleeve 23 as the rotation center is greater than 90 degrees.

[0030] Please see Figures 1 to 4 The air outlet pipe 3 is connected to the bottom of the filter chamber 11. The baffle 9 has through holes at equal intervals. The filter chamber 11 is equipped with support baskets 31 at equal intervals. The tops of the multiple sets of support baskets 31 are connected through corresponding through holes and located in the clean air chamber 10. The outer wall of the support basket 31 is fitted with filter bags 32. The tops of the support baskets 31 and filter bags 32 have outlets. The top of the support baskets 31 is fixedly connected with a U-shaped rod 81.

[0031] It should be noted that: the support basket 31 enters the filter chamber 11 through the through hole on the baffle 9. The tops of both the support basket 31 and the filter bag 32 are bound by retaining rings with a diameter larger than the through hole. Therefore, the tops of the support basket 31 and the filter bag 32 are confined within the clean gas chamber 10. The retaining ring of the support basket 31 is above the retaining ring of the filter bag 32. Natural gas enters the interior from the outside of the filter bag 32 and enters the clean gas chamber 10 from the top outlet of the support basket 31. When the cover plate 12 seals the top of the filter seat 8, it squeezes the U-shaped rod 81, causing the support basket 31 to squeeze the filter bag 32, ensuring that the filter bag 32 is not deformed by the impact of natural gas, thus affecting the filtration efficiency.

[0032] The working principle of the energy-saving and emission-reducing purification device for natural gas power generation provided by this utility model is as follows:

[0033] Natural gas purification:

[0034] Natural gas enters cylinder 1 through the inlet pipe 2 on one side. Guided by the downward-facing spiral inlet rail 4, the natural gas rotates spirally from top to bottom along the inner wall of cylinder 1. Larger particles and other impurities in the natural gas are thrown towards the inner wall of cylinder 1 and separated from the natural gas under the action of centrifugal force. Under the action of gravity, they slide down the wall to the discharge port 6 and enter the dust collection seat 7. Due to the high-speed rotation of the airflow, a negative pressure is generated in the central axis area. After the impurities are removed, the natural gas reaches the bottom of the cone 5 and is attracted by the negative pressure. Turning upwards, it rotates upwards along the axis of the cone 5, and finally the natural gas is discharged from the gas outlet pipe 3 at the top of the cylinder 1. After leaving the gas outlet pipe 3, the natural gas enters the filter chamber 11 in the filter seat 8. Under the action of atmospheric pressure, the natural gas enters the interior from the outside of the filter bag 32. The filter bag 32 intercepts the smaller impurities in the natural gas, so that the natural gas enters the clean gas chamber 10 from the top outlet of the support basket 31, and then flows from the outlet of the filter seat 8 to other treatment devices such as the desulfurization device. The treated natural gas is discharged into the ignition device for combustion and power generation.

[0035] Replace filter bag 32:

[0036] The purification device stops working, and the drive motor 21 is started, causing the threaded rod 22, which is fixedly connected to the output end of the drive motor 21, to rotate counterclockwise. The threaded rod 22 drives the threaded slider 24, which is connected to it, to rise along the threaded rod 22 within the sleeve 23. The slider 24 is fixedly connected to the push block 25. The slider 24 drives the push block 25 to slide and rise in the vertical direction of the L-shaped slide groove 28. The push block 25 drives the lifting cylinder 26, which is fixedly connected to its top, to rise. The lifting cylinder 26 is fixedly connected to the connecting rod 27, which is fixedly connected to the cover plate 12. As the cover plate 12 rises synchronously with the lifting cylinder 26, and the push block 25 finishes its vertical stroke in the L-shaped groove 28, the cover plate 12 is positioned above the filter seat 8. At this time, the threaded rod 22 continues to rotate counterclockwise, and the slider 24 rotates counterclockwise along with the threaded rod 22. The push block 25 slides horizontally within the L-shaped groove 28, causing the lifting cylinder 26 to rotate counterclockwise around the axis of the slider 24. The connecting rod 27 and the cover plate 12 rotate with the lifting cylinder 26. When the push block 25 finishes its horizontal stroke in the L-shaped groove 28, the cover plate... Rotate cover 12 clockwise to move it away from filter base 8, so that the top of filter base 8 is not blocked by cover 12. When cover 12 is raised, it no longer squeezes the U-shaped rod 81 fixedly connected to the top of support basket 31. Therefore, after cover 12 is fully opened, support basket 31 is lifted by U-shaped rod 81, so that the retaining ring at the top of support basket 31 no longer squeezes the retaining ring at the top of filter bag 32. Remove old filter bag 32, put new filter bag 32 into the through hole on baffle 9, and then put support basket 31 into new filter bag 32. The retaining ring at the top of support basket 31 squeezes the top of filter bag 32. When the retaining ring of the filter seat 8 is turned on, the drive motor 21 is started and rotated clockwise. The threaded rod 22 drives the slider 24 to rotate clockwise as well. The push block 25 finishes its horizontal stroke in the L-shaped groove 28. The cover plate 12 rotates counterclockwise back to the top of the filter seat 8. The cover plate 12 and the filter seat 8 are on the same axis. The L-shaped groove 28 restricts the push block 25 from continuing to rotate. The push block 25 slides downward in the vertical direction of the L-shaped groove 28. The push block 25 finishes its horizontal stroke in the L-shaped groove 28. The cover plate 12 squeezes the sealing ring 71 to achieve a seal on the top of the filter seat 8.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
