Description

Technical Field

[0001] This utility model relates to the field of oxidation furnace technology, and more specifically, to an oxidation furnace that produces uniform oxidation. Background Technology

[0002] An oxidation furnace is a common laboratory piece of equipment. It is a high-temperature electric furnace that is precisely designed and manufactured. It can use oxygen or air to carry out oxidation or reduction reactions on substances under high temperature conditions. Oxidation furnaces can be designed and manufactured in different models and specifications according to different applications and reaction conditions.

[0003] A search revealed that utility model patent CN216693581U discloses a high-efficiency CO oxidizer, comprising an oxidizer body, a filter box on one side of the oxidizer body, a waste gas inlet fixedly connected to the side of the filter box away from the oxidizer body, an air inlet fixedly connected to the front of the filter box, and a connecting pipe fixedly connected to the side of the filter box near the oxidizer. The end of the connecting pipe away from the filter box extends into the interior of the oxidizer. A combustion chamber is provided inside the oxidizer body. This patent, by setting up a filter box, waste gas inlet, air inlet, connecting pipe, oxidizer body, ignition assembly, combustion chamber, and exhaust pipe, has the advantage of being able to fully mix with air before the waste gas is oxidized, reducing the carbon monoxide concentration in the oxidizing gas. It solves the problem that existing carbon monoxide oxidizers cannot completely oxidize when the carbon monoxide concentration in the waste gas is high.

[0004] However, the aforementioned patents have the following shortcomings: the mixing of carbon monoxide and air between the filter box and the mixing box is not conducive to ensuring uniform mixing, and the mixed gas in the mixing box can only be introduced into the middle of the combustion chamber, which is not conducive to the ignition component fully igniting it, affecting the completeness and uniformity of carbon monoxide oxidation. To address this, we propose an oxidation furnace for uniform oxidation. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide an oxidation furnace with uniform oxidation.

A waste gas inlet pipe 5 is fixedly sleeved on one side of the mixing cylinder 4, and an air inlet pipe 6 is fixedly sleeved on the other side of the mixing cylinder 4. A bearing 7 is fixedly sleeved at the bottom of the inner cavity of the mixing cylinder 4. A transmission rod 8 is fixedly sleeved on the inner side of the bearing 7. The top end of the transmission rod 8 extends through the conical mixing pipe 3 and the gas guide pipe 2 to the inner cavity of the furnace body 1 and is provided with a dispersion mechanism 14. Multiple drive plates 9 are fixedly connected to the side of the bottom end of the transmission rod 8. A spiral blade 10 is provided on the outer side of the top end of the transmission rod 8. The spiral blade 10 is located in the inner cavity of the gas guide pipe 2. An exhaust mechanism 13 is provided at the top of the furnace body 1. A catalytic bed 15 is provided in the inner cavity of the furnace body 1. An igniter 16 is provided in the inner cavity of the furnace body 1.

[0027] For details, please refer to Figure 2 The dispersing mechanism 14 includes an inverted conical seat 11 fixedly connected to the top of the transmission rod 8, and a plurality of agitating blades 12 are fixedly connected to the side of the inverted conical seat 11.

[0028] In this embodiment, the transmission rod 8 drives the inverted conical seat 11 and the stirring blade 12 to rotate synchronously. The inverted conical seat 11 guides the mixed gas entering the furnace body 1 from the gas guide pipe 2 to the side of the inner cavity of the furnace body 1, and the stirring blade 12 stirs the mixed gas, so that the mixed gas moves evenly to the upper part of the inner cavity of the furnace body 1, so that the igniter 16 can ignite the mixed gas containing carbon monoxide.

[0029] For details, please refer to Figure 1 and Figure 2 The top of the furnace body 1 is fixedly connected to an exhaust pipe 17. The top surface of the exhaust pipe 17 is provided with multiple exhaust holes 18. An activated carbon adsorption layer 19 is fixedly sleeved inside the exhaust pipe 17.

[0030] In this embodiment, the exhaust gas generated in the furnace body 1 is discharged through the exhaust pipe 17 and the exhaust hole 18, and the odor in the exhaust gas is adsorbed by the activated carbon adsorption layer 19.

[0031] For details, please refer to Figure 1 A control panel 21 is fixedly installed on the front of the furnace body 1.

[0032] In this embodiment, the device is controlled using the control panel 21.

[0033] For details, please refer to Figure 1 The bottom surface of the furnace body 1 is fixedly connected with multiple support columns 20.

[0034] In this embodiment, the device is supported by multiple support columns 20.

[0035] For details, please refer to Figure 1 and Figure 2 The drive plate 9 is located at the same height as the exhaust gas inlet pipe 5 and the air inlet pipe 6.

[0036] In this embodiment, the gas introduced through the exhaust gas inlet pipe 5 and the air inlet pipe 6 is ensured to drive the drive plate 9 and the transmission rod 8 to rotate.

[0037] Working principle: In operation, exhaust gas containing carbon monoxide is first introduced into the inner cavity of mixing cylinder 4 through exhaust gas inlet pipe 5, while air is simultaneously introduced into the inner cavity of mixing cylinder 4 through air inlet pipe 6. The exhaust gas introduced through exhaust gas inlet pipe 5 and the air introduced through air inlet pipe 6 drive the drive plate 9 and transmission rod 8 to rotate. The transmission rod 8 drives the spiral blade 10, inverted conical seat 11, and stirring blade 12 to rotate synchronously. In addition, the gas between the two drive plates 9 can collide and mix. Then, the exhaust gas and air enter the upper part of the inner cavity of mixing cylinder 4, and the exhaust gas and air mix in the conical mixing pipe 3. The mixed gas then enters the air guide pipe 2. The rotating helical blades 10 guide the gas into the inner cavity of the furnace body 1. As the mixed gas moves inside the helical blades 10, the mixing time is increased. Then, the mixed gas entering the inner cavity of the furnace body 1 is guided by the side of the bottom of the inverted conical seat 11, so that the mixed gas enters between the rotating agitator blades 12. The agitator blades 12 agitate the mixed gas, so that the mixed gas moves evenly upward between the catalytic bed 15 and the igniter 16. Finally, the igniter 16 ignites the mixed gas, thereby oxidizing the carbon monoxide in the exhaust gas into carbon dioxide, and the treated gas is discharged from the exhaust pipe 17 and the exhaust port 18.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
