Description

Technical Field

[0001] This utility model relates to the technical field of exhaust gas treatment devices, specifically a catalytic oxidation device for treating exhaust gas from chemical storage tanks. Background Technology

[0002] Chemical storage tanks generate a large amount of industrial waste gas during use, and the large-scale emission of industrial waste gas is one of the main causes of air pollution. Effective treatment of industrial waste gas to achieve emission standards is one of the effective ways to alleviate air pollution.

[0003] Existing catalytic oxidation devices for treating exhaust gas from chemical storage tanks generally adopt a tower structure, mainly consisting of an iron-based catalyst packing bed that catalyzes oxidation and a hydrogen peroxide spraying system. However, in actual use, the catalyst packing bed absorbs more impurities in the upper layer than in the lower layer, resulting in uneven reaction and affecting the catalysis of subsequent waste gas. At the same time, it is inconvenient to regularly replace and clean the entire catalyst. Therefore, we propose a catalytic oxidation device for treating exhaust gas from chemical storage tanks. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A catalytic oxidation device for treating tail gas from a chemical storage tank includes: a body assembly and a loading assembly disposed on the body assembly; the loading assembly includes a material bed mechanism disposed in the middle of the body assembly, a limiting mechanism disposed on the side of the material bed mechanism, and a vibration mechanism installed in the limiting mechanism; the material bed mechanism includes a material bed frame installed in the middle of the body assembly, a motor connected to one end of the material bed frame, a material bed plate fixed in the material bed frame, a torsion spring shaft installed on the side of the material bed plate, and a movable plate fixed on the torsion spring shaft.

[0008] In a preferred embodiment, the present invention can be further configured such that: the tower body is provided with manholes located on the upper and lower sides of the material loading assembly.

[0009] In a preferred embodiment, the present invention can be further configured such that: both the inner side of the material bed frame and the material bed plate are provided with mesh.

[0013] The above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0014] 1. This utility model uses a material loading component to drive the material bed frame to rotate via a motor, thereby flipping the catalyst inside the material bed frame. This allows the catalyst in multiple locations to be used evenly and fully, greatly improving the catalytic efficiency of the catalyst. At the same time, it is convenient to replace and clean the catalyst uniformly after the flipping is completed, making it highly practical.

[0015] 2. This utility model, through the material loading component, can, after the inlet and outlet are opened, work with a vibrator to drive the vibrating rod to vibrate, thereby transmitting the vibration to the material bed frame, which facilitates the filling and discharge of catalyst in the material bed frame.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0023] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0024] The following describes, with reference to the accompanying drawings, some embodiments of a catalytic oxidation device for treating exhaust gas from a chemical storage tank, which provides a solution for this utility model.

[0025] Combination Figure 1-3 As shown, the present invention provides a catalytic oxidation device for treating tail gas from a chemical storage tank, comprising: a body assembly 100 and a material loading assembly 200 disposed on the body assembly 100.

[0026] The loading assembly 200 includes a material bed mechanism disposed in the middle of the body assembly 100, a limiting mechanism disposed on the side of the material bed mechanism, and a vibration mechanism installed in the limiting mechanism. The material bed mechanism includes a material bed frame 210 installed in the middle of the body assembly 100, a motor 220 connected to one end of the material bed frame 210, a material bed plate 230 fixed in the material bed frame 210, a torsion spring shaft 240 installed on the side of the material bed plate 230, and a movable plate 250 fixed on the torsion spring shaft 240. Through the loading assembly 200, the motor 220 can drive the material bed frame 210 to rotate, thereby flipping the catalyst in the material bed frame 210, so that the catalyst in multiple positions can be used evenly and fully, which greatly improves the catalytic efficiency of the catalyst. At the same time, it is convenient to replace and clean the catalyst uniformly after the flipping is completed, which is highly practical.

[0027] Specifically, the machine body component 100 includes a tower body 110, a sprayer 120 disposed on the upper part of the tower body 110, and an air outlet 130 and an air inlet 140 connected to both ends of the tower body 110. The exhaust gas enters through the air inlet 140. After the surface of the catalyst in the material bed frame 210 is sprayed by the hydrogen peroxide spraying system, an H2O2 film is formed, and highly oxidizing hydroxyl radicals (OH) and atomic oxygen (O) are generated. In turn, the pollutants in the exhaust gas are removed through catalytic oxidation reaction, so as to achieve the purpose of exhaust gas meeting emission standards.

[0028] Furthermore, the tower body 110 is provided with manholes 150 located on the upper and lower sides of the material loading assembly 200. The corresponding inlet and outlet ports 212 can be opened through the manholes 150 to realize the addition and discharge of catalyst in the material bed frame 210.

[0029] On the other hand, both the inner side of the material bed frame 210 and the material bed plate 230 are provided with mesh 211, which can restrict the catalyst and prevent debris from falling off the catalyst, making it highly practical.

[0030] Furthermore, the limiting mechanism includes limiting plates 260 disposed on both sides of the material bed frame 210 and a groove 270 formed in the middle of the limiting plates 260. The limiting plates 260 can limit the two sides of the material bed frame 210, so that the exhaust gas only passes through the catalyst inside the material bed frame 210. The groove 270 is an arc-shaped groove, and the curvature of the surface meets the rotation requirements of the material bed frame 210 and fits snugly, so that the material bed frame 210 can rotate between the limiting plates 260. At the same time, after rotating to the horizontal position, the corner of the material bed frame 210 contacts the two sides of the limiting plates 260, which plays a limiting role and prevents the gas from being discharged directly downward from the groove 270.

[0031] It should be noted that the vibration mechanism includes a vibrating rod 280 embedded at both ends of the limiting plate 260 and a vibrator 290 connected to the vibrating rod 280. The vibration can be transmitted to the material bed frame 210, thereby accelerating the filling and discharge of the catalyst in the material bed frame 210.

[0032] Furthermore, the material bed frame 210 is provided with an inlet / outlet 212 in the middle, which facilitates opening the material bed frame 210 for feeding and discharging materials.

[0033] The working principle and usage process of this utility model are as follows: First, open the upper manhole 150, then open the inlet and outlet ports 212, and put the catalyst into the material bed frame 210 in sequence. Excess catalyst will press the movable plate 250 to tilt, so that the catalyst will be continuously discharged downward and layered as needed until the filling is completed. During operation, the exhaust gas enters from the air inlet 140, is acted upon by the catalyst in the material bed frame 210, and is then sprayed by the sprayer 120. Finally, it is discharged from the air outlet 130. At the same time, the motor 220 periodically drives the material bed frame 210 to rotate. For the opposite side of the material bed frame 210, the catalyst on the new side can be rotated to the right below.

[0034] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
