[0028] Reference Figures 1 to 5 In one embodiment of the utility model, a waste gas treatment device with uniform use effect includes:

[0029] The air duct 100 is circumferentially closed and has an air passage 110 formed in the middle. The air duct 100 includes a first rectangular section 120, a columnar section 130, and a second rectangular section 140. The first rectangular section 120 and the second rectangular section 140 are connected to each other through the side wall of the columnar section 130. The top and bottom of the columnar section 130 are respectively a top cover plate 131 and a bottom cover plate 132. The top cover plate 131 and / or the bottom cover plate 132 are detachably arranged. The width of the first rectangular section 120 and the second rectangular section 140 is one-half to two-thirds of the width of the columnar section 130.

[0030] The catalytic assembly 200 includes a catalytic functional part 210, a supporting circular plate 220 and a cylindrical mesh plate 230 arranged on the outer periphery of the top of the supporting circular plate 220, the diameter of the supporting circular plate 220 matches the inner diameter of the columnar segment 130, the catalytic functional part 210 is filled in the cylindrical mesh plate 230, the supporting circular plate 220 can be rotatably arranged on the upper surface of the bottom cover plate 132, wherein a through hole is arranged in the middle of the bottom cover plate 132 corresponding to the center of the supporting circular plate 220.

[0031] In the prior art, since the direction of the airflow is fixed, the use status of the adsorption processing functional unit at the side where the airflow enters and the side where the airflow flows out is quite different, and thus the entire adsorption processing functional unit cannot work efficiently.

[0032] In the utility model, the air duct 100 is circumferentially closed and an air path 110 is formed in the middle. The air duct 100 includes a first rectangular section 120, a columnar section 130 and a second rectangular section 140 which are connected to each other. Considering that the matching area between the first rectangular section 120 and the columnar section 130 and the matching area between the second rectangular section 140 and the columnar section 130 are large, the height of the first rectangular section 120 and the height of the second rectangular section 140 can be 90% to 110% of the height of the columnar section 130. The width of the first rectangular section 120 and the second rectangular section 140 is one-half to two-thirds of the width of the columnar section 130. Taking the first rectangular section 120 as an example, when the width of the first rectangular section 120 is closer to the width of the columnar section 130, the unevenness of the adsorption in the width direction of the air duct 100 is increased. The first rectangular section 120 and the second rectangular section 140 are connected by the side wall of the columnar section 130. The top and bottom of the columnar section 130 are respectively a top cover plate 131 and a bottom cover plate 132, and the top cover plate 131 and / or the bottom cover plate 132 are detachable. One of the top cover plate 131 and the bottom cover plate 132 can be detached to provide a basis for the subsequent installation of the catalytic assembly 200.

[0033] The catalytic assembly 200 includes a catalytic functional part 210, a supporting circular plate 220 and a cylindrical mesh plate 230 arranged on the top of the supporting circular plate 220. The catalytic functional part 210 is filled in the cylindrical mesh plate 230. The catalytic functional part 210 can be various types of adsorption materials. The supporting circular plate 220 can be rotatably arranged on the upper surface of the bottom cover plate 132. The rotation action of the supporting circular plate 220 can be manual, motor-driven or self-driven. Regardless of the driving method, a through hole needs to be provided in the middle of the bottom cover plate 132 corresponding to the center of the supporting circular plate 220, and the through hole provides a basis for the rotation of the supporting circular plate 220. The cylindrical mesh plate 230 fixes the catalytic functional part 210, and the rotation of the catalytic assembly 200 realizes a uniform adsorption degree of each part of the catalytic functional part 210.

[0034] In summary, the air duct 100 includes a first rectangular section 120, a columnar section 130 and a second rectangular section 140 which are interconnected; the width of the first rectangular section 120 and the second rectangular section 140 is one half to two thirds of the width of the columnar section 130; the catalytic assembly 200 can be rotatably arranged on the upper surface of the bottom cover plate 132, and the cylindrical mesh plate 230 fixes the catalytic functional part 210, and the rotation of the catalytic assembly 200 realizes uniform adsorption degree of each part of the catalytic functional part 210 in the cylindrical mesh plate 230.

[0035] Reference Figures 3 to 4 In one embodiment, it further includes a driving motor 300, and the driving motor 300 is used to drive the catalytic component 200 to rotate.

[0036] In this embodiment, the catalyst assembly 200 is driven to rotate by introducing a driving motor 300. In a specific implementation process, the output end of the driving motor 300 is connected to the supporting circular plate 220, so that the rotation of the driving motor 300 can drive the catalyst assembly 200 to rotate. In a preferred embodiment, a speed reduction mechanism can also be introduced to optimize the driving process of the catalyst assembly 200.

[0037] Reference Figure 5 In one embodiment, the exhaust gas treatment device further includes a wind wheel assembly 400, and the wind wheel assembly 400 is disposed in the first rectangular section 120, and the wind wheel assembly 400 and the catalytic assembly 200 are linked via gears or belts.

[0038] In this embodiment, since there is airflow passing through the air duct pipe 100, the wind wheel assembly 400 rotates driven by the airflow. The wind wheel assembly 400 is installed on the air duct pipe 100 through a bearing structure, so that smooth rotation can be achieved; the rotation of the wind wheel assembly 400 is transmitted to the catalytic assembly 200, achieving a self-driving effect. The linkage between the two is achieved through a gear mechanism or a belt system. The structural type of the wind wheel assembly 400 can also be diverse, depending on whether it can be driven by the airflow. It is particularly noted that when the speed of the airflow in the air duct pipe 100 is relatively high, the rotation speed of the wind wheel assembly 400 naturally increases, and finally drives the rotation speed of the catalytic assembly 200 to increase, which can naturally adapt to the needs of use without the need for a separate controller.

[0039] In one embodiment, the transmission ratio between the wind wheel assembly 400 and the catalytic assembly 200 is greater than 20.

[0040] In this embodiment, considering that the torque provided by the wind wheel assembly 400 is relatively small and the rotational speed required by the catalytic assembly 200 is also relatively small, the transmission ratio between the wind wheel assembly 400 and the catalytic assembly 200 is limited to greater than 20, so that the wind wheel assembly 400 can drive the catalytic assembly 200 more smoothly.

[0041] In one embodiment, a rotation speed sensor is provided corresponding to the wind wheel assembly 400 .

[0042] In this embodiment, the speed of the airflow in the air duct 100 is measured by measuring the speed of the wind wheel assembly 400. The types of transmission sensors can be various, for example, a Hall type sensor can be selected. The relevant data of the speed sensor can be transmitted to an external controller by wire or wirelessly, and the user can master the operation of the exhaust gas treatment device through the above controller.

[0043] Reference Figures 1 to 2 In one embodiment, a covering circular plate 240 is disposed on the top of the cylindrical mesh plate 230 to close the cylindrical mesh plate 230 .

[0044] In this embodiment, a cover plate 240 is disposed on the top of the cylindrical mesh plate 230 to protect the catalytic functional part 210 in the cylindrical mesh plate 230 and reduce the risk of accidental detachment of the catalytic functional part 210. The cover plate 240 and the cylindrical mesh plate 230 can be connected in various ways, such as a clamp.

[0045] Reference Figures 1 to 2 In one embodiment, the first rectangular section 120 is detachably provided with a primary filter component 410 and a high efficiency filter component 420 both of which cut off the conduction thereof.

[0046] In this embodiment, a primary filter assembly 410 and a high-efficiency filter assembly 420 are added upstream of the catalytic assembly 200 to ensure the normal operation of the catalytic assembly 200. The physical filtering effect of the primary filter assembly 410 and the high-efficiency filter assembly 420 filters the airflow in the air duct 100 and performs maintenance at a certain period, thereby reducing particles from entering the catalytic assembly 200.

[0047] In one embodiment, the primary filter assembly 410 and the high efficiency filter assembly 420 are inserted from the side or bottom of the first rectangular section 120 .

[0048] In this embodiment, considering that in some cases the exhaust gas treatment device is hoisted, the primary filter assembly 410 and the high efficiency filter assembly 420 are arranged to be side mounted or bottom mounted, so as to provide convenience for installation and maintenance.

[0049] In one embodiment, the primary filter component 410 is of a metal wire type, and the high efficiency filter component 420 is of a synthetic fiber felt type.

[0050] In this embodiment, common models of primary filter components 410 and high-efficiency filter components 420 are provided for selection, which have the advantages of mature procurement and reliable performance.

[0051] Reference Figures 4 to 5 In one embodiment, a first air pressure testing portion 510 and a second air pressure testing portion 520 are respectively provided in the spaces corresponding to the first rectangular section 120 and the second rectangular section 140 .

[0052] In this embodiment, the working life of the catalyst assembly 200 can be determined by testing the difference in air pressure between the first rectangular section 120 and the second rectangular section 140. For example, when the pressure difference between the first air pressure test section 510 and the second air pressure test section 520 is small, it means that the remaining service life of the catalyst assembly 200 is long, and vice versa. It should be noted that it is not necessary to test the air pressure on both sides. The ultimate requirement is only to obtain the pressure difference on both sides, and to determine the length of the service life through the value of the pressure difference.

[0053] In summary, the utility model provides an exhaust gas treatment device with a uniform use effect, and the air duct pipe 100 includes a first rectangular section 120, a columnar section 130 and a second rectangular section 140 which are interconnected; the width of the first rectangular section 120 and the second rectangular section 140 is one half to two thirds of the width of the columnar section 130; the catalytic component 200 can be rotatably arranged on the upper surface of the bottom cover plate 132, and the cylindrical mesh plate 230 fixes the catalytic functional part 210, and the rotation of the catalytic component 200 realizes the uniform adsorption degree of each part of the catalytic functional part 210 in the cylindrical mesh plate 230.
