[0004] However, the above device still has shortcomings:

[0005] 1. When purifying organic waste gas, impurities in the organic waste gas will remain on the filter. If it cannot be cleaned in time, it will affect the efficiency of organic waste gas purification.

[0006] 2. When organic waste gas is transported into the activated carbon, it will always contact part of the activated carbon first, and then diffuse into other activated carbons, which causes the activity of some activated carbons to decrease rapidly, while other activated carbons cannot play a purification effect. Utility Model Content

To this end, the utility model proposes a high-efficiency activated carbon organic waste gas catalytic purification device, which solves the problem that when purifying organic waste gas, impurities in the organic waste gas will remain on the filter screen, and if they cannot be cleaned in time, the purification efficiency of the organic waste gas will be affected.

[0008] To achieve the above purpose, the utility model proposes a high-efficiency activated carbon organic waste gas catalytic purification device, including a fine purification box, the bottom of which is fixedly connected to an air intake pipe, and a cleaning component is arranged inside the air intake pipe, wherein:

At this time, the organic waste gas enters the air intake duct at a certain speed driven by the fan. The airflow generated by the organic waste gas drives the fan blades to rotate. Through the rotation of the fan blades, the fan blades drive the cleaning plate to rotate with the rotating shaft as the axis point, thereby achieving the cleaning effect.

DETAILED DESCRIPTION

[0022] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-3 As shown, a high-efficiency activated carbon organic waste gas catalytic purification device includes a fine purification box 1, the bottom of the fine purification box 1 is fixedly connected to an air intake pipe 2, and a cleaning component 4 is arranged inside the air intake pipe 2, wherein:

[0024] The cleaning assembly 4 includes a rotating shaft 41, the outer side of the rotating shaft 41 is rotatably connected to a fixed plate 42, both ends of the fixed plate 42 are fixedly connected to the inner wall of the air intake pipe 2, the rotating shaft 41 is arranged on the side wall of one end of the air intake pipe 2 and is fixedly connected to a fan blade 43, and the top of the rotating shaft 41 is fixedly connected to a cleaning plate 44.

[0025] A filter plate 5 is fixedly connected to the interior of the fine purification box 1 , and a cleaning plate 44 is arranged on the lower surface of the filter plate 5 .

[0026] When the organic waste gas is subjected to the refinement operation, the organic waste gas enters the air intake duct 2 under the action of the fan. At this time, the organic waste gas enters the air intake duct 2 at a certain speed driven by the fan. The airflow generated by the organic waste gas drives the fan blades 43 to rotate. Through the rotation of the fan blades 43, the fan blades 43 drive the cleaning plate 44 to rotate with the rotating shaft 41 as the axis point, thereby achieving the cleaning effect.

[0027] By using the flow rate of the exhaust gas itself as a power source, no additional energy consumption is required to drive the cleaning component 4, thereby significantly reducing operating costs and reducing carbon emissions caused by energy consumption, which is beneficial to environmental protection. The cleaning component 4 also reduces the need for manual intervention and reduces the frequency of regular cleaning or replacement of the filter plate 5, thereby reducing the workload of maintenance personnel and related maintenance costs. At the same time, it also avoids downtime caused by clogging of the filter plate 5, improves the overall operating efficiency of the system, and effectively prevents problems such as increased system pressure and decreased processing efficiency caused by clogging of the filter plate 5, thereby enhancing the stability and reliability of the entire exhaust gas treatment system.

[0028] A plurality of brackets 101 are fixedly connected to the bottom of the fine purification box 1 , and an air outlet pipe 3 is fixedly connected to the top of the fine purification box 1 .

[0029] A hot air device 103 and a motor 102 are fixedly connected to both sides of the fine purification box 1 .

[0030] The side wall of the motor 102 is rotatably connected with a hollow stirring shaft 104. The hollow stirring shaft 104 is arranged on the side wall of the fine purification box 1 and is fixedly connected with a plurality of hollow stirring rods 105. Both the hollow stirring shaft 104 and the hollow stirring rods 105 are hollow.

[0031] During filtering, the motor 102 drives the hollow stirring shaft 104 to rotate, and the hollow stirring rod 105 can stir the activated carbon on the filter plate 5 through the rotation of the hollow stirring shaft 104, thereby effectively avoiding that the activated carbon at the bottom always comes into contact with the organic waste gas first, thereby reducing the activity of the activated carbon at the bottom. The activated carbon can be evenly mixed by stirring to avoid some of the activated carbon from losing its activity. Secondly, hot air is passed through the interior of the hollow stirring shaft 104 and the hollow stirring rod 105. The clean hot air can heat the activated carbon to improve its activity, and the heating and stirring operations are carried out simultaneously, so that all the activated carbon can be fully in contact with the hot air.

[0032] The hollow stirring shaft 104 is disposed above the filter plate 5 , one end of the hollow stirring shaft 104 is rotatably connected to the motor 102 , and the other end of the hollow stirring shaft 104 is plugged into the hot air device 103 .

[0033] Working principle: When the organic waste gas is subjected to the refinement operation, the organic waste gas enters the air intake duct 2 under the action of the fan. At this time, the organic waste gas enters the air intake duct 2 at a certain speed driven by the fan. The airflow generated by the organic waste gas drives the fan blades 43 to rotate. Through the rotation of the fan blades 43, the fan blades 43 drive the cleaning plate 44 to rotate with the rotating shaft 41 as the axis point, thereby achieving the cleaning effect.

[0034] During filtering, the motor 102 drives the hollow stirring shaft 104 to rotate, and the hollow stirring rod 105 can stir the activated carbon on the filter plate 5 through the rotation of the hollow stirring shaft 104, thereby effectively avoiding that the activated carbon at the bottom always comes into contact with the organic waste gas first, thereby reducing the activity of the activated carbon at the bottom. The activated carbon can be evenly mixed by stirring to avoid some of the activated carbon from losing its activity. Secondly, hot air is passed through the interior of the hollow stirring shaft 104 and the hollow stirring rod 105. The clean hot air can heat the activated carbon to improve its activity, and the heating and stirring operations are carried out simultaneously, so that all the activated carbon can be fully in contact with the hot air.

[0035] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
