[0026] The present application provides a smoke guiding device for the coke oven top, which includes a smoke guiding horizontal pipe 1. A connecting seat 2 for connecting with the bottom of the smoke guiding vehicle on the coke oven top is arranged on the smoke guiding horizontal pipe 1. A smoke guiding vertical pipe 3 is connected to the smoke guiding horizontal pipe 1. The lower end of the smoke guiding vertical pipe 3 is connected to a flue gas treatment box 4. The flue gas treatment box 4 is connected with a smoke guiding sleeve 5 for connecting with the smoke guiding hole at the top of the carbonization chamber. A purification component 6 and a dust removal component 7 are arranged in the flue gas treatment box 4 from top to bottom. The dust removal component 7 and the purification component 6 are used to preliminarily remove dust and purify the flue gas, simplify the subsequent treatment process, shorten the treatment time, and improve the flue gas treatment efficiency. Specifically, the dust removal component 7 includes a conical smoke guiding cover 71 and a filter net 72. The conical smoke guiding cover 71 is fixedly arranged in the flue gas treatment box 4. The bottom of the conical smoke guiding cover 71 is communicated with the smoke guiding sleeve 5. The filter net 72 is fixedly arranged at the top of the conical smoke guiding cover 71. When the coke oven flue gas enters the flue gas treatment box 4 through the smoke guiding sleeve 5, it first passes through the dust removal component 7, then through the purification component 6, and finally is guided through the smoke guiding vertical pipe 3 and the smoke guiding horizontal pipe 1. When the coke oven flue gas passes through the conical smoke guiding cover 71, it gathers towards the middle of the conical smoke guiding cover 71. The small dust particles in the coke oven flue gas gather with each other to form large dust particles, and finally fall downward under the action of gravity. The filter net 72 can filter the dust particles in the coke oven flue gas to achieve the preliminary dust removal of the coke oven flue gas.

[0027] The purification component 6 includes an upper smoke guiding plate 61, a lower smoke guiding plate 62, and a purification packing layer 63. The upper smoke guiding plate 61 and the lower smoke guiding plate 62 are fixedly arranged in the flue gas treatment box 4 from top to bottom. A plurality of through holes are evenly arranged on both the upper smoke guiding plate 61 and the lower smoke guiding plate 62. The purification packing layer 63 is located between the upper smoke guiding plate 61 and the lower smoke guiding plate 62. After passing through the filter net 72 of the dust removal component 7, the coke oven flue gas moves upward, passes through the lower smoke guiding plate 62 evenly and enters the purification packing layer 63 for purification, and finally passes through the upper smoke guiding plate 61 and enters the smoke guiding horizontal pipe 1 through the smoke guiding vertical pipe 3. Among them, in this embodiment, the purification packing layer 63 is made of activated carbon, which can adsorb and filter the dust particles in the coke oven flue gas and preliminarily purify the flue gas.

[0028] The flue gas treatment box 4 is provided with a cleaning component 8 for cleaning the filter net 72. A driving motor 9 for driving the cleaning component 8 to operate is arranged on one side of the flue gas treatment box 4. By driving the cleaning component 8 with the driving motor 9 to clean the filter net 72, it is possible to prevent the filter net 72 from being blocked by soot particles in the coke oven flue gas, thus affecting the normal flow of the coke oven flue gas.

[0029] The cleaning component 8 includes a support frame 81, a rotating shaft 82, a cleaning brush 83, a first bevel gear 84 and a second bevel gear 85. The rotating shaft 82 is rotatably arranged in the flue gas treatment box 4 through the support frame 81. The lower end of the rotating shaft 82 extends to the bottom of the filter net 72. The cleaning brush 83 is fixedly arranged at the lower end of the rotating shaft 82. The bristles of the cleaning brush 83 are in contact with the filter net 72. The first bevel gear 84 is fixedly arranged on the rotating shaft 82. The output shaft of the driving motor 9 extends into the flue gas treatment box 4. The second bevel gear 85 is fixedly arranged on the output shaft of the driving motor 9. The first bevel gear 84 meshes with the second bevel gear 85. Specifically, the support frame 81 is fixedly arranged in the flue gas treatment box 4, and the rotating shaft 82 is rotatably arranged on the support frame 81. By driving the second bevel gear 85 to rotate with the driving motor 9, the second bevel gear 85 drives the first bevel gear 84 to rotate, the first bevel gear 84 drives the rotating shaft 82 to rotate, and the rotating shaft 82 drives the cleaning brush 83 to rotate. The soot particles adhered to the filter net 72 are scraped off by the rotating cleaning brush 83.

[0030] A high-temperature resistant sealing ring 10 is fixedly arranged at the lower end of the smoke guiding sleeve 5. When the smoke guiding sleeve 5 moves downward, the high-temperature resistant sealing ring 10 is pressed tightly against the smoke guiding hole at the top of the carbonization chamber, which can achieve a sealing effect and prevent the coke oven flue gas from leaking.

[0031] A transparent observation window 11 is arranged on one side of the flue gas treatment box 4. Through the transparent observation window 11, the situation of the filter net 72 inside the flue gas treatment box 4 can be observed, and the driving motor 9 can be started according to actual needs to clean the filter net 72.

[0032] A first connecting flange 12 is arranged at one end of the smoke guiding horizontal pipe 1, and a second connecting flange 13 is arranged at the other end of the smoke guiding horizontal pipe 1. A sealing end plate 14 is connected to the first connecting flange 12. The smoke guiding horizontal pipe 1 can be connected to an existing external smoke guiding hose through the second connecting flange 13. The smoke guiding horizontal pipe 1 guides the coke oven flue gas into the external smoke guiding hose, and the coke oven flue gas is guided into the next process for treatment by the smoke guiding hose.

[0033] Working principle: When in use, the smoke guiding horizontal pipe 1 is connected to the bottom of the smoke guiding car on the furnace top in the prior art through the connecting seat 2, and the second connecting flange 13 is connected to the existing external smoke guiding hose. Before the smoke guiding starts, open the smoke guiding hole cover plate at the top of the carbonization chamber, and then drive the smoke guiding sleeve 5 at the bottom of the smoke guiding car on the furnace top to descend through the driving device, so that the high-temperature resistant sealing ring 10 is pressed tightly against the smoke guiding hole at the top of the carbonization chamber. The coke oven gas on the coke oven top enters the smoke guiding sleeve 5 through the smoke guiding hole at the top of the carbonization chamber, then enters the flue gas treatment box 4, and is preliminarily dust-removed and purified through the dust removal component 7 and the purification component 6. Then it successively passes through the smoke guiding vertical pipe 3 and the smoke guiding horizontal pipe 1 and enters the smoke guiding hose, and the coke oven gas is introduced into the next process for treatment through the smoke guiding hose.

[0034] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
