Description

Technical Field

[0001] The utility model relates to the technical field of raw tape production, in particular to an exhaust gas treatment device. Background Art

[0002] During the production process of raw tape, waste gas will be generated. In order to prevent the waste gas from polluting the air, the waste gas is treated through a treatment device. When treating the waste gas, the waste gas is catalytically treated by the catalyst filler. When the waste gas comes into contact with the catalyst filler, it moves from the bottom of the catalyst filler to the upper end of the catalyst filler. After a long period of waste gas treatment, the waste gas treatment effect of the catalyst filler at the bottom is reduced, and the height of the catalyst filler layer is certain. After the catalyst filler at the bottom fails, the waste gas treatment time is reduced during the upward movement of the waste gas, thereby reducing the waste gas treatment effect. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Example 1

[0023] Reference Figure 1-3 , an exhaust gas treatment device, comprising a housing 1, wherein:

[0024] The bottom end of the shell 1 is fixedly connected to a supporting foot, the bottom end of the shell 1 is connected to an air inlet pipe, the upper end of the shell 1 is connected to an air outlet pipe, a material holding mechanism 2 is fixedly connected inside the shell 1, a catalyst packing layer is provided inside the material holding mechanism 2, a turning mechanism 3 for stirring the catalyst packing layer is connected to the shell 1, a controller is fixedly connected to the shell 1, and the controller signal is connected to the turning mechanism 3, the exhaust gas is introduced into the shell 1 through the air inlet pipe, the exhaust gas in the shell 1 enters the material holding mechanism 2, the catalyst packing layer in the material holding mechanism 2 contacts with the exhaust gas, and the exhaust gas is treated, and at the same time the controller controls the turning mechanism 3 to be powered on and started, and after the turning mechanism 3 is started, the catalyst packing layer in the material holding mechanism 2 is stirred, so that different catalysts are located at the bottom end of the interior of the material holding mechanism 2, and the catalysts inside the material holding mechanism 2 are mixed, thereby improving the catalyst's treatment effect on the exhaust gas;

[0025] The turning mechanism 3 includes a mounting plate 31, which is fixedly connected to the housing 1. A motor 32 is fixedly connected to the mounting plate 31. The motor 32 is a servo motor. The motor 32 is connected to the controller through a wire. The output end of the motor 32 is fixedly connected to a rotating shaft 33. One end of the rotating shaft 33 extends into the material holding mechanism 2 and is connected to a turning plate 34. The turning plate 34 cooperates with the material holding mechanism 2. The controller controls the motor 32 to be powered on and started. After the motor 32 is started, the rotating shaft 33 is driven to rotate a set number of circles. The rotating shaft 33 drives the turning plate 34 to rotate. After the turning plate 34 rotates, the catalyst in the material holding mechanism 2 is stirred, so that different catalysts in the material holding mechanism 2 are located at the bottom end of the material holding mechanism 2. The catalysts in the material holding mechanism 2 are mixed, thereby improving the catalyst's treatment effect on exhaust gas.

[0026] The material holding mechanism 2 includes an open frame 21, which is fixedly connected to the shell 1. An anti-corrosion layer is sprayed on the open frame 21, and the anti-corrosion layer is a polyethylene anti-corrosion layer. The anti-corrosion layer protects the open frame 21 from corrosion, slows down the corrosion rate of the open frame 21, and extends the service life of the open frame 21. The bottom end of the open frame 21 is fixedly connected to a support net 22, which supports the catalyst packing layer. At the same time, the exhaust gas can pass through the support net 22 and contact the catalyst packing layer. The support net 22 cooperates with the flip plate 34. The upper end of the inner part of the open frame 21 is fixedly connected to a fixed net 23, which blocks the upper end of the open frame 21 to prevent the catalyst packing layer from falling from the upper end of the open frame 21. The mesh aperture of the fixed net 23 is larger than the mesh aperture of the support net 22.

[0027] Working process: exhaust gas is introduced into the shell 1 through the air inlet pipe, and the exhaust gas in the shell 1 enters the material holding mechanism 2. The catalyst packing layer in the material holding mechanism 2 contacts the exhaust gas to treat the exhaust gas. The controller controls the motor 32 to be powered on and started. After the motor 32 is started, it drives the rotating shaft 33 to rotate a set number of circles. The rotating shaft 33 drives the flip plate 34 to rotate. After the flip plate 34 rotates, the catalyst in the material holding mechanism 2 is stirred, so that the different catalysts in the material holding mechanism 2 are located at the bottom end of the inner part of the material holding mechanism 2. The catalysts inside the material holding mechanism 2 are mixed, thereby improving the catalyst's treatment effect on the exhaust gas, and the treated exhaust gas is discharged from the outlet pipe.

[0028] Example 2

[0029] After the exhaust gas is catalytically treated by the catalyst, the treated exhaust gas contains a certain amount of smoke and dust, which cannot be treated by the catalyst. Figure 4 As another preferred embodiment of the present invention, on the basis of embodiment 1, a filter mechanism 4 is fixedly connected to the inner upper end of the shell 1, and the filter mechanism 4 includes a filter screen 41, which is fixedly connected to the inner upper end of the shell 1, and a collecting plate 42 is fixedly connected to the bottom end of the filter screen 41. The collecting plate 42 is an arc-shaped plate, and strip holes 43 are provided on both sides of the collecting plate 42. The exhaust gas after catalytic treatment passes through the strip holes 43 through the collecting plate 42 and contacts the filter screen 41. The filter screen 41 filters the smoke in the exhaust gas, and part of the filtered smoke falls onto the collecting plate 42, thereby reducing the smoke falling into the material holding mechanism 2. The smoke in the exhaust gas is filtered by the filter screen 41, thereby improving the exhaust gas treatment effect.

[0030] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
