Description

Technical Field

[0001] This utility model belongs to the field of filtration equipment technology, specifically relating to a high-temperature gas filtration device that facilitates dust unloading. Background Technology

[0002] High-temperature gas filtration devices are used to remove impurities from high-temperature gases. Dust-laden gas enters the filtration device through the gas inlet at the bottom. As the gas passes through the filter module, impurities are trapped on its surface. Clean gas reaches the top of the filtration device and exits through the gas outlet. As the amount of impurities on the filter module surface increases, the gas permeability decreases. Therefore, backflushing of the filter module is necessary to blow off the impurities. However, in actual operation, a discharge auxiliary device needs to be designed to ensure the smooth discharge of the blown-off impurities. Existing technology typically uses a vibrating motor to assist discharge (e.g., CN201410757734.4), but this affects the structural safety of the device itself. Some devices also have a backflushing structure at the discharge port, but using room-temperature gas for backflushing can cause condensation, making the discharge port more prone to clogging.

[0025] This utility model discloses a high-temperature gas filtration device that facilitates dust unloading, such as... Figure 1-2 As shown, the device includes a main body 1 and a discharge hopper 11 located at the bottom of the main body 1. A tube sheet 12 is installed inside the main body 1. The tube sheet 12 forms a clean gas side 13 and a dust-laden gas side 14 on its upper and lower sides, respectively. The clean gas side 13 and the dust-laden gas side 14 are connected to an outlet 15 and an inlet 16, respectively. A filter backflushing device is installed at the top of the clean gas side 13, corresponding to the filter module inside the dust-laden gas side 14. The discharge hopper 11 is located on the dust-laden gas side 14, away from the clean gas side. The end of the clean gas side 13 and the bottom of the discharge hopper 11 have a discharge port 17 coaxially arranged with the device body 1. During normal filtration, the dust-laden gas enters the dust-laden gas side 14 through the lower air inlet 16. After being filtered by the filter module, the dust-laden gas enters the upper clean gas side 13 and is discharged outward through the air outlet 15. During backflushing, the backflushing device provides the reverse airflow from the normal filtration, that is, it blows off the impurities on the surface of the filter module from top to bottom and discharges them outward through the discharge port 17 of the discharge hopper 11.

[0026] To prevent blockage of the discharge port 17 during unloading, this invention includes a backflushing device 2 connected to the discharge hopper 11. The backflushing device 2 comprises a distribution ring pipe 21 arranged on the outer periphery of the discharge hopper 11, multiple backflushing pipes 22 evenly spaced along the circumference of the distribution ring pipe 21 and extending into the discharge hopper 11, and a gas storage tank 23 for supplying backflushing gas to the distribution ring pipe 21. The gas storage tank 23 is equipped with a heating component 24. Specifically, the design of the distribution ring pipe 21 and the backflushing pipes 22 improves the uniformity of the backflushing airflow. The backflushing pipes 22 extend into the discharge hopper 11. A back-blowing port 25 is provided at one end, extending toward the discharge port 17 at the bottom of the discharge hopper 11. The angle between the back-blowing port 25 and the axial direction of the device body 1 is 0-90°. Preferably, the angle between the back-blowing port 25 and the axial direction of the device body 1 is 0-5°, which enables the blown gas to form a cyclone at the discharge port 17, further improving the discharge effect. A connecting pipe 26 is provided between the gas storage tank 23 and the distribution ring pipe 21. A pulse control valve 27 is provided on the connecting pipe 26. The pulse control valve 27 can periodically blow pulse high-pressure gas under program control to assist in discharge.

[0027] In use, the heating component 24 first heats the backflush gas in the gas storage tank 23. The heated backflush gas enters the distribution ring pipe 21 through the pulse control valve 27, and then is blown to the discharge port 17 through the backflush pipe 22.

[0028] In summary, the high-temperature gas filtration device for easy dust unloading provided by this utility model has a simple structure and is easy to operate. It realizes the function of backflushing the unloading port with high-temperature and high-pressure gas, and has the advantages of good backflushing effect, high unloading efficiency, low cost, and extended service life of the device. It has great market value and is worth promoting and applying widely.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
