Description

Technical Field

[0001] This utility model relates to the technical field of regenerative oxidation equipment, specifically a uniform air distribution structure for a regenerative oxidation device. Background Technology

[0002] Regenerative thermal oxidizers (RTOs) are a type of high-efficiency equipment for treating organic waste gas. Compared with traditional catalytic combustion and direct-fired thermal oxidizers (TO), they have the advantages of high thermal efficiency (≥95%), low operating costs, and the ability to handle large volumes of low-concentration waste gas. When the concentration is slightly higher, secondary waste heat recovery can also be performed, which greatly reduces production and operating costs. However, current RTOs have the following shortcomings when in use.

[0003] First, the airflow entering the boiler is often not dispersed enough, resulting in uneven airflow and incomplete combustion, which leads to waste and environmental pollution. Second, the airflow velocity entering the boiler is often too high, which is not conducive to complete combustion of the gas. Therefore, improvements are needed. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a uniform air distribution structure for a regenerative oxidation device. By setting a dispersion mechanism inside the air duct and the circular pipe, the airflow can be uniformly dispersed, making the air intake of the device more uniform. Furthermore, an air distribution plate is installed inside the protective frame, which solves the problem of uneven air distribution in current equipment, resulting in incomplete gas combustion and waste.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] A uniform air distribution structure for a regenerative oxidation device includes a duct and a circular pipe connected to the air inlet of the duct. A dispersion mechanism is provided inside the duct and the circular pipe. The dispersion mechanism includes a support frame fixedly connected to the inner wall of the circular pipe and a rotating rod rotatably connected to the support frame. An array of fan blades is fixedly connected to a support at the top of the rotating rod, and a fixing frame is fixedly connected to the rotating rod. A turntable is fixed to the top of the fixing frame, and the turntable has an array of air inlets. The turntable is rotatably connected to a rotating seat on the inner wall of the duct. When high-pressure gas enters the inner side of the duct through the circular pipe, it drives the fan blades and the rotating rod to rotate, achieving airflow dispersion inside the duct. Furthermore, when the airflow exits through the air inlets, it undergoes secondary dispersion, facilitating uniform airflow distribution.

[0009] Furthermore, a flow guiding mechanism is fixedly connected to the upper part of the air duct. The flow guiding mechanism includes an annular plate fixedly connected to the inner wall of the air duct, and flow guiding plates equidistantly arranged on the inner side of the annular plate. An inclined flow guiding groove is formed between two adjacent flow guiding plates.

[0010] Furthermore, the exhaust end of the air duct is connected to a protective frame, and an air distribution plate is fixedly connected to the inner side of the protective frame. The air distribution plate includes an air plate body fixedly connected to the inner wall of the protective frame, and the air plate body has an array of cross-shaped air outlet holes.

[0011] Furthermore, the air deflector body has round holes between the cross-shaped air outlet holes.

[0012] Furthermore, the air inlet end of the circular tube is connected to an air inlet pipe via a flange.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, the present invention provides a uniform air distribution structure for a regenerative oxidation device, which has the following beneficial effects:

[0015] 1. This utility model, by installing a dispersion mechanism inside the air duct and circular pipe, mainly consists of a support frame, a rotating rod, fan blades, a fixed frame, and a turntable. When external gas enters the inner side of the air duct through the circular pipe, it will agitate the fan blades, causing the fan blades and rotating rod to rotate. When the fan blades rotate, they can agitate the airflow, causing part of the airflow to disperse outward, thus achieving uniform airflow dispersion. The dispersion force and range depend on the size of the fan blades. When the rotating rod rotates, it can also rotate the fixed frame and the turntable. When the airflow is discharged through the air inlet, the rotating turntable can cause the discharged airflow to rotate, and multiple airflows can merge, thus achieving secondary airflow dispersion and avoiding uneven air distribution. Furthermore, an air distribution plate is set inside the protective frame, with cross-shaped air outlet holes and circular holes, which further achieves uniform airflow dispersion.

[0016] 2. This utility model provides a flow guiding mechanism on the upper inner side of the air duct. The flow guiding mechanism consists of an annular plate and a flow guiding plate. The flow guiding plate is inclined, which makes the flow guiding groove inclined. This method can not only make the airflow discharge more uniform, but also reduce the wind speed and make the gas combustion more complete. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0024] Example

[0025] like Figure 1 , Figure 2 and Figure 5 As shown in the figure, a uniform air distribution structure for a heat storage oxidation device according to one embodiment of the present invention includes a wind duct 1 and a circular pipe 7 connected to the air inlet end of the wind duct 1. A dispersion mechanism 6 is provided inside the wind duct 1 and the circular pipe 7. The dispersion mechanism 6 includes a support frame 601 fixedly connected to the inner wall of the circular pipe 7 and a rotating rod 602 rotatably connected to the support frame 601. An array of fan blades 604 are fixedly connected to a support 603 provided at the top of the rotating rod 602. A fixed frame 605 is fixedly connected to the air duct 1. A turntable 606 is fixed on the top of the fixed frame 605. An array of air inlets 607 are opened on the turntable 606. The turntable 606 is rotatably connected to a rotating seat 5 set on the inner wall of the air duct 1. When high-pressure gas enters the inner side of the air duct 1 through the round pipe 7, it will drive the fan blades 604 and the rotating rod 602 to rotate, thereby dispersing the airflow inside the air duct 1. When the airflow is discharged through the air inlets 607, it can be dispersed again, which facilitates the uniform distribution of the airflow.

[0026] It should be noted that the air duct 1, protective frame 2, and circular pipe 7 constitute the main body of the device. By setting a dispersion mechanism 6 inside the air duct 1 and circular pipe 7, external airflow can enter the inside of the air duct 1 through the circular pipe 7. The dispersion mechanism 6 disperses the airflow, making the air intake of the device more uniform. The dispersion mechanism 6 mainly consists of a support frame 601, a rotating rod 602, a support 603, a fan blade 604, a fixing frame 605, and a turntable 606. The support frame 601 is used for the rotating installation of the rotating rod 602. 03 is equipped with fan blades 604. When the airflow enters the inner side of the air duct 1, it will come into contact with the fan blades 604, causing the fan blades 604 to rotate. When the fan blades 604 rotate, the airflow will be dispersed and dispersed to the outside, and then evenly filled to the inner side of the air duct 1. It should also be noted that the size and amplitude of the airflow diffusion depend on the size of the fan blades 604. Afterwards, the airflow is discharged through the air inlet 607. When the rotating rod 602 rotates, it will drive the turntable 606 to rotate. Therefore, the gas discharged through the air inlet 607 will also rotate, which will further disperse and mix the gas.

[0027] like Figure 1 and Figure 3 As shown, in some embodiments, a flow guiding mechanism 4 is fixedly connected to the upper part of the air duct 1. The flow guiding mechanism 4 includes an annular plate 401 fixedly connected to the inner wall of the air duct 1, and flow guiding plates 402 equidistantly arranged on the inner side of the annular plate 401. An inclined flow guiding groove 403 is formed between two adjacent flow guiding plates 402.

[0028] It should be noted that by setting the flow guiding mechanism 4 on the upper inner side of the air duct 1, the airflow can be discharged evenly and the flow velocity can be reduced. The main body of the flow guiding mechanism 4 is an annular plate 401 and a flow guiding plate 402. The flow guiding plate 402 is set at an angle, so that the airflow is discharged at an angle, which can slow down the flow velocity and make the gas combustion more complete.

[0029] like Figure 1 , Figure 4 and Figure 5 As shown, in some embodiments, the exhaust end of the air duct 1 is connected to the protective frame 2, and the inner side of the protective frame 2 is fixedly connected to the air distribution plate 3. The air distribution plate 3 includes an air plate body 301 fixedly connected to the inner wall of the protective frame 2, and the air plate body 301 is provided with an array of cross-shaped air outlet holes 302.

[0030] It should be noted that the cross-shaped air outlet 302 has a cross-shaped structure, which facilitates the fusion and flow of gas when it flows out, making the gas dispersion more uniform.

[0031] like Figure 4 As shown, in some embodiments, the air deflector body 301 has round holes 303 between the cross-shaped air outlet holes 302, so that the gas can be discharged quickly.

[0032] like Figure 1 As shown, in some embodiments, the air inlet end of the circular tube 7 is connected to the air inlet pipe 8 via a flange.

[0033] It should be noted that a fan can be installed on the air inlet pipe 8 during actual use to allow gas to enter quickly.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
