Abstract
Description
Technical Field
[0001] This utility model relates to the field of waste gas treatment technology, specifically a waste gas catalytic combustion device. Background Technology
[0002] Catalytic combustion is a combustion method that uses a suitable catalyst to decompose and oxidize combustible substances in harmful gases at a lower temperature. Specifically, in catalytic combustion, the catalyst lowers the activation energy of the reaction, allowing flameless combustion to occur at a lower ignition temperature of 200–300°C. The oxidation of organic matter occurs on the surface of the solid catalyst, simultaneously producing CO2 and H2O and releasing a large amount of heat.
[0003] However, in traditionally used catalytic combustion equipment, the catalyst carrier and the combustion equipment shell are often an integrated structure, which makes it inconvenient to replace the catalyst carrier, resulting in many inconveniences in practical applications. Although existing technologies have proposed the application of separate combustion chambers, it is still necessary to disassemble the pipeline when replacing the catalyst carrier, which is not only labor-intensive but also affects the normal operating time of the catalytic combustion equipment. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waste gas catalytic combustion device, comprising a horizontal shell including a bottom shell and a top cover plate hinged to the rear end top surface of the bottom shell; the bottom shell has longitudinally extending support rails on both side walls; a sleeve hole is provided in the middle of the front wall of the bottom shell; gears are rotatably installed at the bottom of the rear ends of both side walls of the inner cavity of the bottom shell; a lower support body is slidably fitted onto the bottom of the inner cavity of the bottom shell; a strip plate is fixed to the bottom end of both side walls of the lower support body; a strip groove is provided in the middle of the top surface of the strip plate; a rack that meshes with the bottom of the gear is fixed in the strip groove; an upper support body is slidably fitted onto the top of the inner cavity of the bottom shell. The upper support body has two strip plates fixed to the bottom of its two side walls, which are supported on the support rails. The bottom surface of the strip plate has a groove in the middle, and a rack that meshes with the top of the gear is fixed in the groove. The telescopic cylinder piston is fixed to the middle of the front wall of the bottom shell, and the piston rod end is fixed to the front wall of the lower support body through the sleeve hole. The front wall of the top of the combustion furnace has a rectangular opening. The rear end of the bottom shell is fixedly connected to the outer edge of the rectangular opening. The inner wall of the top of the combustion furnace has frame-shaped support plates fixed at the lower edge and middle of the rectangular opening, respectively.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0025] Please see Figure 1-6 The present invention provides a technical solution: a waste gas catalytic combustion device, wherein the front wall of the top of the combustion furnace 1 is provided with a plurality of rectangular openings 1.1 along the vertical direction, and fixing strips 1.2 are fixed on both sides of the rectangular openings 1.1 on the front wall of the top of the combustion furnace 1, and frame-shaped support plates 1.3 are fixed on the inner wall of the top of the combustion furnace 1 at the lower edge and middle of the rectangular openings 1.1, respectively.
[0026] The horizontal housing 2 includes a bottom housing 2.1 and a top cover plate 2.2 hinged to the rear top surface of the bottom housing 2.1. Support rails 2.1.1 extending longitudinally are provided on both side walls of the bottom housing 2.1. A sleeve hole 2.1.2 is provided in the middle of the front wall of the bottom housing 2.1. Gears 2.3 are rotatably installed on the rear bottom of both side walls of the inner cavity of the bottom housing 2.1. Connecting strips 2.4 are fixed to both sides of the rear end of the bottom housing 2.1, and are bolted to corresponding fixing strips 1.2, meaning the rear end of the bottom housing 2.1 is directly opposite the rectangular opening 1.1. Furthermore, a handle is installed in the middle of the front wall of the top cover plate 2.2 to facilitate its flipping.
[0027] The lower support 3 is slidably fitted into the bottom of the inner cavity of the bottom shell 2.1. Strip plates 3.3 are fixed to the bottom ends of the two side walls of the lower support 3.3. A strip groove 3.3.1 is provided in the middle of the top surface of the strip plate 3.3. A rack 3.3.2, which meshes with the bottom of the gear 2.3, is fixed inside the strip groove 3.3.1. A rectangular groove 3.1, nested and matched with the catalyst carrier 6, is provided in the middle of the lower support 3.1. Support bosses 3.2 are provided at the bottom of the front and rear walls of the inner cavity of the rectangular groove 3.1.
[0028] The upper support 4 is slidably fitted onto the top of the inner cavity of the bottom shell 2.1. The bottom ends of the two side walls of the upper support 4 are respectively fixed with strip plates 4.3, which are supported on the outer side of the support rails 2.1.1. A strip groove 4.3.1 is provided in the middle of the bottom surface of the strip plate 4.3. A rack 4.3.2, which meshes with the top of the gear 2.3, is fixed inside the strip groove 4.3.1. The upper support 4 also has a rectangular groove 4.1 in the middle that nests and matches the catalyst carrier 6. Support bosses 4.2 are respectively provided at the bottom of the front and rear walls of the inner cavity of the rectangular groove 4.1.
[0029] The piston cylinder of the telescopic cylinder 5 is fixed to the middle of the front wall of the bottom housing 2.1, and the end of the piston rod is fixed to the front wall of the lower support body 3 through the sleeve hole 2.1.2.
[0030] The catalyst support 6 has support strips 6.1 at the top of the front and rear walls respectively, and the support strips 6.1 have grooves 6.2 in the middle.
[0031] In summary, the catalyst carrier 6 is respectively installed in rectangular groove 1 3.1 and rectangular groove 2 4.1 and 4.1, and the support strip 6.1 is respectively supported on support boss 1 3.2 and support boss 2 4.2.
[0032] The push-pull action of the telescopic cylinder 5 facilitates the direct push-pull action of the lower support body 3. Due to the meshing action of the rack 3.3.2 and the gear 2.3, when the lower support body 3 slides longitudinally, it will drive the gear 2.3 to rotate. The rotating gear 2.3 will then drive the upper support body 4 to slide in the opposite direction relative to the lower support body 3 through the rack 4.3.2.
[0033] When the upper support 4 and the lower support 3 are located inside the top shell of the combustion furnace 1, the strip plate 3.3 and the strip plate 4.3 are supported on the corresponding frame support plate 1.3. When the lower support 3 is located inside the top shell of the combustion furnace 1, the upper support 4 is located in the middle of the inner cavity of the horizontal shell 2, and vice versa.
[0034] The catalyst carrier 6, which moves with the lower support 3 or the upper support 4 to the top shell of the combustion furnace 1, participates in the catalytic combustion reaction. The catalyst carrier 6, which moves with the lower support 3 or the upper support 4 to the inner cavity of the horizontal shell 2, can be quickly replaced after the top cover 2.2 is flipped upwards.
