[0026] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0029] Example 1:

[0030] Please see Figures 1-5 This is the first embodiment of the present invention.

[0031] This embodiment provides a desulfurization, denitrification and dust removal device for coke oven flue gas, including a treatment cylinder 1, a gas supply pipe 2 inserted into the upper part of the outer wall of the treatment cylinder 1, a gas outlet pipe 3 extending out from the lower part of the outer wall of the treatment cylinder 1, and a mounting cavity 4 opened inside the treatment cylinder 1, and a filter mechanism 5 is installed inside the mounting cavity 4.

[0032] The filter mechanism 5 includes a sleeve 501, which is sleeved on the bottom end of the processing cylinder 1. A penetration block 502 is fixedly installed at the end of the sleeve 501 that penetrates into the processing cylinder 1. A connecting groove 503 is opened at the top of the penetration block 502. A bearing cylinder 504 extends out from the inside of the connecting groove 503. A filter cylinder 505 extends out from the inside of the bearing cylinder 504.

[0033] Specifically, a placement cylinder 506 is inserted between the carrier cylinder 504 and the filter cylinder 505, and an adsorption packing layer 507 is embedded inside the placement cylinder 506.

[0034] Furthermore, the adsorption packing layer 507 is housed in the placement cylinder 506, making it easy to place inside the treatment cylinder 1. The adsorption packing layer 507 is made of activated carbon or other materials that can filter substances such as sulfur and nitrates.

[0035] Specifically, a fixing block 509 is fixedly installed at the bottom of the filter cartridge 505, and a limiting groove 508 is opened on one side of the connecting groove 503 at the top of the block 502.

[0036] Furthermore, by limiting the fixed block 509 through the limiting groove 508, the stability of the filter cartridge 505 located inside the processing cartridge 1 can be improved.

[0037] Specifically, sleeve 501 is threadedly connected to processing cylinder 1, and sleeve 501 is threadedly connected to bearing cylinder 504 through connecting groove 503.

[0038] Furthermore, the threaded connection between sleeve 501, processing cylinder 1, and bearing cylinder 504 facilitates unified disassembly and assembly, enabling internal maintenance and cleaning.

[0039] Specifically, the structure of the bearing cylinder 504 is a hollow structure, and the bearing cylinder 504 and the processing cylinder 1 are an integral structure.

[0040] Furthermore, the upper end of the bearing cylinder 504 is closed and the lower end is hollow, which allows gas to enter the filter cylinder 505 for filtration at the upper end and allows the filtered gas to flow out at the lower end, enter the mounting cavity 4, and finally flow out through the gas outlet pipe 3.

[0041] In use, the treatment cylinder 1 is connected to the coke oven flue gas equipment through the gas supply pipe 2, and is filtered through the internal filter cylinder 505 and the adsorption packing layer 507 inside the placement cylinder 506. While removing dust, it can also achieve desulfurization and denitrification. The sleeve 501 is threadedly connected to the treatment cylinder 1, so that the fixing block 509 can be limited by the limiting groove 508. The carrying filter cylinder 505 is located inside the treatment cylinder 1, and is threadedly connected to the carrying cylinder 504 through the connecting groove 503 opened in the through block 502, which further improves the stability after fixing, and can support the placement cylinder 506 located outside the filter cylinder 505. After filtration, the gas enters the placement chamber 4 and flows out through the gas outlet pipe 3.

[0042] In summary, by setting up the filter cartridge 505, dust and impurities can be filtered, and the adsorption packing layer 507 can achieve the effect of dry desulfurization and denitrification, which can improve the gas purification effect. Through the cooperation of the sleeve 501 and the insertion block 502, it is threadedly connected to the treatment cartridge 1 and the bearing cartridge 504, which facilitates disassembly and assembly and improves the stability between them. After disassembly and assembly, the filter cartridge 505 and the mounting cartridge 506 can be easily disassembled, assembled, maintained and cleaned.

[0043] Example 2:

[0044] Please see Figures 1-3 This is the second embodiment of the present utility model.

[0045] Specifically, a through hole 6 is provided on the outer wall of the bearing cylinder 504 at the position corresponding to the gas supply pipe 2, and a cleaning mechanism 7 is provided inside the filter cylinder 505.

[0046] Furthermore, the through hole 6 allows the gas supply pipe 2 to pass through the carrier cylinder 504 and contact the filter cylinder 505, allowing the gas to directly enter the interior of the filter cylinder 505 and avoid entering the mounting cavity 4.

[0047] Specifically, the cleaning mechanism 7 includes a servo motor 701, which is embedded in the top of the processing cylinder 1. A connecting rod 702 is fixedly installed at the power output end of the servo motor 701, and a rotating plate 703 is fixedly installed at the bottom end of the connecting rod 702.

[0048] Furthermore, the servo motor 701, in conjunction with the connecting rod 702, enables the rotating plate 703 to rotate, allowing the cleaning mechanism 7 to operate automatically and avoiding the inconvenience of manual cleaning by staff.

[0049] Specifically, abutment plates 704 are fixedly installed on both sides of the bottom end of the rotating plate 703, and soft brushes 705 are embedded in the outer wall of the abutment plates 704.

[0050] Furthermore, the soft brush 705 fixed to the contact plate 704 adheres to the filter cartridge 505 and can rotate along the inside of the filter cartridge 505, thereby scraping off the adsorbed dust and impurities and avoiding excessive adsorption that could cause blockage.

[0051] In use, the servo motor 701 is controlled by the control terminal of the device, which can drive the connecting rod 702 to make the rotating plate 703 drive the contact plate 704 to rotate, and make the soft brush 705 fit against the filter cartridge 505 to rotate, scraping off the adsorbed impurities, etc., to avoid clogging and affecting the filtration effect.

[0052] In summary, the power provided by the servo motor 701 enables the soft brush 705 to rotate in contact with the filter cartridge 505, scraping away adsorbed dust and impurities, thus preventing clogging. The scraped dust and impurities fall directly onto the insertion block 502 of the sleeve 501 and remain within the range of the filter cartridge 505 to prevent diffusion, facilitating the subsequent disassembly and assembly of the sleeve 501 for unified cleaning and collection of these dust and impurities.
