[0027] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the chimney body 1 as a whole is a conical structure that is wide at the bottom and narrow at the top, and multiple groups of layer plates 3 are arranged at equal distances. The specifications of the layer plates 3 match the inner diameter of the chimney body 1 at the corresponding position, and the surface of the layer plates 3 is provided with a microporous structure. At the same time, the surface of the layer plates 3 is rotatably connected to a manhole plate, and the escalator 4 is distributed between the manhole plates on the surfaces of the corresponding upper and lower layer plates 3 at an angle of 45°.
[0028] In this embodiment, Figure 1 and Figure 3 As shown, the first guide assembly 5 and the second guide assembly 6 are both composed of a plurality of single plates, and the single plates are symmetrically distributed between the inner walls of the chimney body 1 along the axis point of the chimney body 1, and one end of the single plate is in correspondence with the contour of the inner wall of the chimney body 1, and the other end is in a "Z" shape.

The first guide assembly 5 is spaced a certain distance from the corresponding layer plate 3 above, and at the same time, the inner wall of the chimney body 1 is fixedly connected with several groups of symmetrically distributed second guide assemblies 6 above the corresponding layer plate 3 with the smallest specifications.
[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the large flue gas volume and space-saving chimney reaction catalytic device, when in use, works as follows:
[0031] First, the external smoke inlet pipe 9 on one side of the chimney body 1 can be connected to the external smoke source that needs to be treated, and the smoke enters the treatment box 2 through the external smoke inlet pipe 9. A primary screen plate 201 is arranged in the treatment box 2. The primary screen plate 201 first contacts the smoke, and the fine mesh holes on its surface can intercept large particles of smoke in the smoke. At the same time, the interior of the treatment box 2 is divided into two independent chambers by the primary screen plate 201, and the built-in smoke exhaust pipe 203 is located above the outer cavity area. When the smoke passes through the primary screen plate 201, the cam assembly 202 rotates, and the spring structure is used to make the primary screen plate 201 vibrate back and forth, thereby adjusting the mesh holes on the surface of the primary screen plate 201. The holes are cleaned to prevent the mesh from being blocked. The smoke filtered by the primary screening plate 201 is discharged from the built-in smoke exhaust pipe 203 on the top of the processing box 2. The smoke discharged from the built-in smoke exhaust pipe 203 flows upward and contacts the upper layer plate 3. The layer plates 3 are arranged in multiple groups at equal distances. The specifications match the inner diameter of the chimney body 1 at the corresponding position. The surface is provided with a microporous structure. The filling groove 7 is a through structure, which is connected with the micropores of the layer plate 3 and is distributed along the corresponding surface diameter of the layer plate 3. The filler is laid inside. The filler can be honeycomb activated carbon. The activated carbon has good adsorption performance and can effectively adsorb harmful substances in the smoke. In the process of flue gas flowing upward, it will pass through the micropores of the layer plate 3 and fully contact the filler in the filler groove 7. Under the action of the filler, a catalytic reaction will occur to remove some pollutants in the flue gas. A first guide component 5 in the shape of an inverted "eight" is fixedly connected to the top of each layer plate 3, and a second guide component 6 in the shape of an "eight" is fixedly connected to the bottom. The first guide component 5 and the second guide component 6 play a role in guiding the flow direction of the flue gas. On the one hand, the combined structure of the two will hinder the rising path of the flue gas. When the flue gas passes through these individual plates, it needs to constantly change the flow direction, thereby consuming part of the kinetic energy. , so that the rising speed is reduced. On the one hand, since the first guide component 5 and the second guide component 6 evenly disperse the smoke, the flow of the smoke is more stable, avoiding the occurrence of local high-speed flow. Combined with the fan 8 at both ends of the opposite side, when the fan 8 is turned on, the wind force it provides causes the smoke to continue to flow upward, and cooperates with the first guide component 5 and the second guide component 6 to control the rising speed and distribution state of the smoke. For example, when the smoke needs to have a longer contact with the filler, the fan 8 can appropriately reduce the wind force, and at the same time, the first guide component 5 and the second guide component 6 further reduce the smoke speed and prolong the reaction time;When the processing process needs to be accelerated, the fan 8 can increase the wind force, but the first guide assembly 5 and the second guide assembly 6 can still ensure that the smoke rises evenly and stably to avoid a chaotic flow state. The first guide assembly 5, the second guide assembly 6 and the fan 8 of each layer work together to treat the smoke in layers, further improving the treatment effect. The smoke after multi-layer treatment finally rises to the top of the chimney body 1, and is discharged from the external smoke exhaust pipe 10 at the top of the chimney body 1 under the guidance of the top multiple groups of symmetrically distributed second guide assemblies 6. At this time, the pollutant content in the discharged smoke has been greatly reduced. When it is necessary to replace the filler inside the filler slot 7 on a daily basis, the staff can enter the furnace body through the door panel set outside the chimney body 1, and reach the corresponding layer 3 with the help of the escalator 4 and the manhole plate set on the layer 3, and replace the filler and perform equipment maintenance. The escalator 4 is distributed between the manhole plates on the corresponding upper and lower layers 3 at a 45° inclination, which is convenient for the staff to move between each layer. ;
[0032] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected.
