[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-Figure 7 The present invention provides a technical solution: a green and environmentally friendly industrial waste gas treatment system, comprising a reaction tower 11, an air intake pipe and an exhaust pipe, wherein the air intake pipe and the exhaust pipe are respectively arranged at the bottom and the top of the reaction tower 11, and further comprising:

[0034] Filter assembly, the filter assembly consists of a filter mechanism, a material changing mechanism and a cleaning mechanism;

[0035] The filter mechanism includes two filter shells 12, the top and bottom surfaces of the filter shells 12 are filter structures, and the filter shells 12 are filled with filter materials. The exhaust gas can pass through the filter shells 12 and be filtered;

[0036] The material changing mechanism is arranged on the reaction tower 11, and is used to change the filter material in the filter housing 12;

[0037] The cleaning mechanism is disposed in the filter housing 12 , and is used to clean the filter material in the filter housing 12 .

[0038] The waste gas to be treated is injected into the reaction tower 11 from the lower end of the reaction tower 11 through the air inlet pipe, and after being filtered inside the reaction tower 11, it is discharged from the reaction tower 11 through the exhaust pipe at the upper end of the reaction tower 11; in this process, the waste gas to be treated flows from bottom to top; during the flow, the waste gas passes through the filter shells 12 in multiple filter components in turn, and the harmful substances in the waste gas are adsorbed by the filter material inside the filter shell 12. As the harmful substances adsorbed by the filter material gradually increase, the adsorption capacity of the filter material gradually decreases; at this time, the material changing mechanism is started to replace the filter material in the filter shell 12. During the replacement process, the used filter material in the filter shell 12 is cleaned by the cleaning mechanism, and then new filter material is added to the filter shell 12 by the material changing mechanism. It should be noted that the filter material is in solid particle form.

[0039] The present invention provides a material changing mechanism on the reaction tower 11, and the equipment does not need to remove the filter shell 12 from the reaction tower 11 during the process of replacing the filter material, so that the equipment can replace the filter material during the filtration process; the efficiency of the equipment in treating exhaust gas is improved, and the manpower and time cost of replacing the filter material is reduced.

[0040] As a further solution of the present invention, the filtering mechanism also includes two mounting platforms 21 symmetrically arranged on the inner wall of the reaction tower 11, and the side surfaces of the two filter shells 12 are rotatably connected to the side surfaces of the two mounting platforms 21 close to the center of the reaction tower 11, respectively. Both ends of the filter shell 12 are vertically elastically slidably connected with a first sealing strip 22, and the inner wall of the reaction tower 11 is located at both ends of the filter shell 12 and is fixedly connected with sealing strips 23, and the sealing strips 23 are used to seal the gap between the reaction tower 11 and the end of the filter shell 12.

[0041] In the initial state, the filter shell 12 filled with filter material is horizontally arranged on one side of the mounting platform 21. At this time, the mounting platform 21, the filter shell 12, the sealing strip 23 and the first sealing strip 22 are spliced ​​together to form a partition surface, so that the gas in the reaction tower 11 can only flow through the filter mesh structure on the top and bottom surfaces of the filter shell 12; when the filter material in the filter shell 12 needs to be replaced, the corresponding filter shell 12 is driven to rotate to tilt the filter shell 12, and at the same time, the material changing mechanism opens the first sealing strip 22, so that the filter material can be replaced through both ends of the filter shell 12. It should be noted that in actual applications, the filter shell 12 is connected to an externally controlled driving device for driving its rotation. The driving device can be a motor, etc., which is a conventional setting for personnel in this technical field and will not be described in detail.

[0042] The present invention allows the filter material inside the filter shell 12 to leave the filter shell 12 under the action of gravity during the replacement process by tilting the filter shell 12 when replacing the filter material, thereby reducing the difficulty of replacing the filter material.

[0043] As a further solution of the present invention, the material changing mechanism includes two feed pipes 31 and two discharge pipes 32. The feed pipes 31 and the discharge pipes 32 are both arranged through the side wall of the reaction tower 11. The ends of the feed pipes 31 and the discharge pipes 32 located inside the reaction tower 11 are vertically elastically slidably connected with a second sealing strip 33. The feed pipes 31 and the discharge pipes 32 can be sealed and connected with the rotated filter shell 12.

[0044] As the filter shell 12 tilts, the first sealing strips 22 at both ends of the filter shell 12 are respectively pressed against the ends of the corresponding feed pipe 31 and the discharge pipe 32, and the second sealing strips 33 at the ends of the corresponding feed pipe 31 and the discharge pipe 32 are pressed against the filter shell 12, so that the first sealing strip 22 and the second sealing strip 33 are respectively separated from the corresponding ends until the filter shell 12 and the corresponding feed pipe 31 and the discharge pipe 32 are connected (the ends of the filter shell 12, the feed pipe 31 and the discharge pipe 32 are arc-shaped, so as to ensure the sealing of the filter shell 12 and the corresponding feed pipe 31 and the discharge pipe 32 during the connection). At this time, the cleaning mechanism cooperates with gravity to make the used filter material in the filter shell 12 slide into the discharge pipe 32, and finally discharged from the reaction tower 11. Then, new filter material is injected into the feed pipe 31, and the new filter material slides into the filter shell 12 under the action of gravity. When the filter shell 12 is filled with the material again, the filter shell 12 is driven to rotate and reset. During this process, under the action of elastic force, the first sealing strip 22 and the second sealing strip 33 rotate with the filter shell 12, gradually sealing the ends of the feed pipe 31 and the discharge pipe 32 at the ends of the filter shell 12.

[0045] As a further solution of the present invention, the cleaning mechanism includes a first sealing plate 41, which is arranged between the two filter shells 12, and both ends of the first sealing plate 41 are fixedly connected to the inner wall of the reaction tower 11, and the upper and lower ends of the mounting platform 21 are fixedly connected to the second sealing plate 42, and the first sealing plate 41 and the second sealing plate 42 can close the side wall of the filter shell 12 when the filter shell 12 rotates; a sealing mechanism is also connected to the filter shell 12, and the sealing mechanism is used to seal the filter shell 12 after the feed pipe 31 and the discharge pipe 32 are sealed and connected to the filter shell 12. The sealing mechanism includes a filter plate 61 that can be offset and sealed with the top surface of the filter shell 12, and the filter plate 61 is connected to an electric push rod 62 for promoting its reciprocating motion, and a filter plate 43 is arranged on the top surface of the discharge pipe 32, and the filter plate 43 is located in the reaction tower 11 to block the top surface of the filter shell 12, and a scraping mechanism is arranged inside the filter shell 12, and the scraping mechanism is used to scrape the inner wall of the filter shell 12.

[0046] When the filter shell 12 rotates to change the material, the closing mechanism closes the upper end of the filter shell 12. When closed, the electric push rod 62 pushes the filter plate 2 61 to form a dislocation blockage with the top of the filter shell 12, so that the airflow inside the reaction tower 11 enters the filter shell 12 from the lower end of the filter shell 12 when passing through the filter shell 12, and then enters the discharge pipe 32 connected to the filter shell 12, and finally is discharged into the reaction tower 11 through the filter plate 43 at the upper end of the discharge pipe 32 (it should be noted that the discharge is the part of the reaction tower 11 located above the filter shell 12); in this process, the exhaust gas forms an airflow flowing from the feed pipe 31 to the discharge pipe 32 inside the filter shell 12; further, the used filter material in the filter shell 12 is blown into the discharge pipe 32 through the airflow; at the same time, when the feed pipe 31 transports new filter material into the filter shell 12, the airflow can compact the filter material newly entering the filter shell 12 toward the discharge pipe 32, so as to ensure the subsequent filtering effect of the filter shell 12.

[0047] The present invention seals the upper end of the filter shell 12, thereby forming an airflow from the direction of the feed pipe 31 to the direction of the discharge pipe 32 in the filter shell 12, and then uses the airflow to assist in the discharge of used filter material in the filter shell 12 and the compaction of unused filter material in the filter shell 12, thereby improving the replacement efficiency and replacement effect of the filter material.

[0048] As a further solution of the present invention, the scraping mechanism includes a first guide rail 51 and a second guide rail 52. The first guide rail 51 is fixedly connected to the bottom of the filter shell 12, and the second guide rail 52 is longitudinally slidably connected to the bottom of the filter shell 12. The end of the second guide rail 52 close to the feed pipe 31 is rotatably connected to the first connecting rod 53, and the first connecting rod 53 is hinged with a first slider 54. The first slider 54 is laterally slidably connected to the bottom of the filter shell 12, and the first slider 54 is hinged with a second connecting rod 55. The second connecting rod 55 is rotatably connected to the inner wall of the first sealing strip 22. The first guide rail 51 is laterally elastically slidably connected to a plurality of second sliders 56 distributed in an array, and the upper end of the second slider 56 is rotatably connected to the first rotating shaft 57. A toggling leaf 58 is fixedly connected to one side of the first rotating shaft 57, and the lower end of the toggling leaf 58 is fixedly connected to the second rotating shaft 59. The lower end of the second rotating shaft 59 is fixedly connected to the third slider 510, and the third slider 510 is slidably connected to the second guide rail 52, and brushes 511 are fixedly connected to the upper and lower ends of the toggling leaf 58.

[0049] When the connection between the filter housing 12 and the feed pipe 31 and the discharge pipe 32 is completed, the corresponding first sealing strip 22 slides in the vertical direction, so that the second connecting rod 55 moves in the vertical direction along with the first sealing strip 22, and further the second connecting rod 55 pushes the first slider 54 to move in the direction of the second guide rail 52, and further the first slider 54 pushes the second guide rail 52 to move away from the first guide rail 51 through the first connecting rod 53; further the second guide rail 52 drives the second rotating shaft 59 to move away from the first rotating shaft 57 through the third slider 510, so that the toggle leaf 58 on the side wall of the first rotating shaft 57 rotates, so that the toggle leaf 58 is perpendicular to the trajectory of the internal channel of the filter housing 12; further, when the airflow flows from the filter housing 12 to the discharge pipe 32, the airflow drives the toggle leaf 58 to move in the direction of the discharge pipe 32; at this time, the toggle leaf 58 drives the brushes 511 at the upper and lower ends to scrape the upper and lower inner walls of the filter housing 12; when the toggle leaf 58 is moved, the second slider 59 drives the second rotating shaft 59 to move away from the first rotating shaft 57 through the third slider 510, so that the toggle leaf 58 on the side wall of the first rotating shaft 57 rotates, so that the toggle leaf 58 is perpendicular to the trajectory of the internal channel of the filter housing 12; further, when the airflow flows from the filter housing 12 to the discharge pipe 32, the airflow drives the toggle leaf 58 to move in the direction of the discharge pipe 32; at this time, the toggle leaf 58 drives the brushes 511 at the upper and lower ends to scrape the upper and lower inner walls of the filter housing 12; when the toggle leaf 58 is moved After the movable blade 58 moves to the limit of its stroke in the direction of the discharge pipe 32, the closing mechanism cancels the closing of the upper end of the filter shell 12, allowing the airflow to vertically pass through the filter port, and then the toggle blade 58 is reset under the elastic force of the second slider 56. When the toggle blade 58 is reset, the closing mechanism closes the upper end of the filter plate 43 again, allowing the airflow to flow along the channel path inside the filter shell 12, and then blows the toggle blade 58 again, so that the brushes 511 at the upper and lower ends of the toggle blade 58 repeatedly scrape the upper and lower inner walls of the filter shell 12 to assist the filter shell 12 in discharging; when the filter shell 12 is discharged and starts to feed, the reciprocating movement of the toggle blade 58 assists in compacting the filter material; when the filter shell 12 is replaced, the first sealing strip 22 is reset, and the corresponding first guide rail 51, second guide rail 52 and toggle blade 58 are all reset. During this process, the toggle blade 58 rotates, but since the filter material is granular, the rotation of the toggle blade 58 does not affect the filtering effect of the filter material.

[0050] It should be noted that the present invention also aims to protect a green and environmentally friendly industrial waste gas treatment method, which uses a green and environmentally friendly industrial waste gas treatment system to treat industrial waste gas.
