[0002] The flue gas produced by combustion usually contains a variety of components, including carbon dioxide, carbon monoxide, nitrogen oxides, sulfur oxides and heavy metal particles, some of which may be harmful to the environment and human health. If these flue gases are directly discharged into the atmosphere, they will greatly harm the air quality. The flue gases need to be filtered before discharge.

[0003] When filtering smoke, in order to ensure the filtering efficiency of smoke, it is necessary to regularly disassemble and clean the smoke filter element to prevent particles in the smoke from clogging the filter element. Before removing the filter element, the air intake pipe needs to be closed to prevent direct leakage of smoke after the filter element is removed. In actual use, unfiltered smoke will remain between the air intake pipe and the filter element, making it easy for the remaining smoke to leak when the filter element is removed, causing the dismantling personnel to inhale the smoke. For this reason, a smoke treatment device is proposed. Utility Model Content

DETAILED DESCRIPTION

[0022] The present invention is further described below in conjunction with specific embodiments. However, people familiar with the art should understand that the detailed description given here in conjunction with the drawings is for better explanation, and the structure of the present invention necessarily exceeds these limited embodiments. For some equivalent replacement schemes or common means, they are no longer described in detail herein, but still fall within the scope of protection of the present application.

[0023] Figures 1 to 5 It is the best embodiment of the utility model, and the following Figures 1 to 5 The utility model is further described.

[0024] like Figures 1 to 5 As shown, a flue gas treatment device includes a fixed barrel 1, and also includes a base 2 and a top cover 3 arranged outside the fixed barrel 1. A connecting piece 5 for guiding flue gas is provided on the base 2, and a sealing component 4 for controlling flue gas is provided inside the base 2.

[0025] The top cover 3 and the base 2 are respectively arranged at both ends of the fixed barrel 1, and an air inlet pipe 101 is arranged on the outside of the fixed barrel 1, and the air inlet pipe 101 is connected to the fixed barrel 1. An air outlet pipe 301 is arranged on the outside of the top cover 3, and the air outlet pipe 301 is connected to the fixed barrel 1. The connecting piece 5 is arranged between the top cover 3 and the base 2. A filter element 6 is arranged inside the connecting piece 5. The sealing assembly 4 includes a sealing member, which moves relative to the filter element 6, and the moving direction of the sealing member is parallel to the axis of the fixed barrel 1. The sealing member is used to control the connection and disconnection between the connecting piece 5 and the air outlet pipe 301. When in use, the smoke is processed by the filter element 6. When the filter element 6 needs to be cleaned, the top cover 3 is first disassembled to release the limit of the filter element 6, and then the filter element 6 is taken out from the inside of the connecting piece 5. When the filter element 6 is taken out, the sealing assembly 4 is cooperated to block the smoke to be processed to prevent the smoke to be processed from leaking and causing environmental pollution.

[0026] like Figures 1 to 5As shown, the base 2 is provided with a groove 202 at one end relative to the fixed barrel 1. A guide groove is provided inside the base 2, and there are multiple guide grooves. A receiving groove is provided in the middle of the base 2, and the receiving groove is connected to the guide groove. The base 2 blocks the bottom of the fixed barrel 1, thereby providing support for the filter element 6 during use to ensure stability during use. At the same time, the base 2 seals the bottom of the fixed barrel 1 to avoid smoke leakage during the process of treating smoke.

[0027] like Figures 1 to 5 As shown, the top cover 3 is provided with a connecting plate 302 on one side relative to the fixed barrel 1, and there are multiple connecting plates 302, and the connecting plates 302 rotate inside the fixed barrel 1. The connecting plates 302 are provided with connecting grooves 303 on one side of the opposite surface, and the connecting grooves 303 are L-shaped. When in use, the position of the filter element 6 is fixed by the cooperation of the connecting plate 302 and the top cover 3, so as to avoid positional movement relative to the fixed barrel 1 when treating the flue gas, and ensure stability during use.

[0028] like Figures 1 to 5 As shown, the connecting piece 5 includes a fixed tube 501 and a fixed cover 502. The opening direction of the fixed tube 501 is parallel to the axis of the fixed barrel 1. The fixed tube 501 is provided with a connecting hole 503 at one end relative to the base 2, and there are multiple connecting holes 503. The fixed cover 502 is arranged on the outside of the fixed tube 501, and the fixed cover 502 is connected to the fixed tube 501, and the fixed cover 502 is connected to the air intake pipe 101. The fixed tube 501 cooperates with the fixed cover 502 to divide the space inside the fixed barrel 1 to avoid mixing of the flue gas to be treated and the treated flue gas, thereby ensuring stability during use. The fixed cover 502 and the fixed tube 501 are connected through the connecting hole 503, and the top cover 3 is sealed with the top of the fixed tube 501 to avoid leakage of flue gas from the top of the fixed tube 501 during use, thereby ensuring stability during use.

[0029] like Figures 1 to 5As shown, the seal includes a sealing plate 401, a support ring 402, a fixed cone 403 and a first spring 404. The sealing plate 401 slides inside the fixed tube 501, and the sealing plate 401 is provided with a support ring 402 at one end relative to the fixed tube 501, and the support ring 402 abuts against the filter element 6. An air inlet hole is provided on the outer side of the support ring 402, and there are multiple air inlet holes. The fixed cone 403 is arranged at the other end of the sealing plate 401, and the fixed cone 403 is located directly above the accommodating groove. The first spring 404 is arranged inside the groove 202, and the first spring 404 is connected to the sealing plate 401. The sealing assembly 4 also includes a moving part, and the sealing plate 401 slides inside the fixed tube 501. During the sliding process of the sealing plate 401, the sealing plate 401 is guided by the fixed tube 501 to ensure the accuracy of the direction of the sealing plate 401 when it moves. When the filter element 6 is installed inside the fixed tube 501, the filter element 6 abuts against the support ring 402 and pushes the sealing plate 401 downward, so that the smoke to be treated can enter the fixed tube 501 through the connecting hole 503 and the air inlet hole for treatment. When the filter element 6 is disassembled, the sealing plate 401 loses its abutment, so that the sealing plate 401 is driven by the first spring 404 to move upward to the top of the connecting hole 503, thereby closing the channel between the connecting hole 503 and the air inlet hole, avoiding smoke leakage after the filter element 6 is disassembled, and ensuring stability during use.

[0030] like Figures 1 to 5 As shown, the moving member includes a sliding rod 405 and a second spring 406. The sliding rod 405 corresponds to the guide groove. The sliding rod 405 is L-shaped. The sliding rod 405 moves relative to the base 2, and the moving direction of the sliding rod 405 is perpendicular to the axis of the fixed barrel 1. The opposite ends of the sliding rod 405 are against the fixed cone 403. The second spring 406 is provided between the sliding rod 405 and the base 2. The sliding rod 405 is provided with a connecting block on one side relative to the connecting plate 302, and the connecting block is adapted to the connecting groove 303. The opposite end of the sliding rod 405 is in contact with the outer side of the fixed cone 403. When the sealing plate 401 moves downward, the fixed cone 403 moves with the sealing plate 401, so that the fixed cone 403 pushes the sliding rods 405 on both sides to move in the opposite direction. During the reverse movement of the sliding rod 405, the connecting block on the outside of the sliding rod 405 is inserted into the connecting groove 303, so that the sliding rod 405 cooperates with the connecting groove 303 to limit the position of the top cover 3 and the connecting plate 302 relative to the fixed barrel 1, so as to prevent the top cover 3 and the connecting plate 302 from sliding out of the fixed barrel 1 during use. At the same time, the fixed cone 403 pushes the sliding rod 405 to collide with the connecting groove 303, and friction is generated while the collision occurs, so as to prevent the top cover 3 and the connecting plate 302 from rotating relative to the fixed barrel 1 under the action of vibration during use. When the filter element 6 needs to be disassembled, the top cover 3 and the connecting plate 302 are first rotated so that the connecting block can be separated from the connecting groove 303, thereby releasing the limit on the filter element 6, so as to facilitate the disassembly of the filter element 6 during cleaning.
