Description

Technical Field

[0001] This invention relates to the field of waste gas treatment technology, and more specifically, to a catalytic oxidation tower for waste gas treatment. Background Technology

[0002] Waste gas refers to toxic and harmful gases emitted during human production and daily life, particularly from chemical plants, steel mills, pharmaceutical factories, processing and manufacturing plants, as well as coking plants and oil refineries, and from domestic waste gas generated by human life. These emitted waste gases have strong odors, severely pollute the environment, and affect human health. Rubber and plastic waste gas refers to gases containing sulfides and hydrocarbons, which can cause significant harm to the respiration of humans and animals. If large amounts of industrial waste gas are discharged into the atmosphere without treatment, it will inevitably degrade air quality, seriously harm human health, and cause huge losses to the national economy. Currently, waste gas treatment mainly relies on water washing or combustion for purification, resulting in relatively simple structural and functional methods.

[0003] However, it still has some drawbacks in actual use. For example, in the current waste gas treatment, there is a catalytic oxidation tower for waste gas. When the waste gas is oxidized and burned inside the current oxidation tower, the air exchange and transportation inside the oxidation tower only relies on the air exchange port on one side of the oxidation tower. The required amount of oxygen is insufficient to support the complete combustion of the waste gas, resulting in incomplete combustion of the waste gas, which affects the purification effect of the waste gas. At the same time, a large amount of incompletely burned waste gas is discharged outdoors, which still causes serious pollution to the atmosphere.

[0004] Therefore, based on the above, and drawing on years of experience in design, development and manufacturing in the relevant industry, the inventor has researched and improved the existing structure and its shortcomings, and provides a catalytic oxidation tower for waste gas treatment, in order to achieve a more practical value. Summary of the Invention

[0005] To overcome the aforementioned deficiencies of the prior art, embodiments of the present invention provide a catalytic oxidation tower for waste gas treatment. By assembling an air inlet assembly, a rotating assembly, and an oxidation tower, and utilizing their coordinated operation, the air pump is first turned on, and fresh air from the outside is introduced through the air inlet bend, a fixed circular pipe, and a connecting metal pipe into the combustion chamber inside the fixed oxidation tower. Simultaneously, a drive motor drives a drive shaft to rotate on the side of the mounting frame. The drive shaft drives a drive gear to rotate, which in turn drives a driven wheel and a first connecting gear to rotate sequentially, until a second connecting gear is driven to rotate. At this point, the second connecting gear drives the connecting pipe inside it to rotate, and then through the fixed circular pipe at its bottom and the connecting... The metal tube rotates in a regular circular motion, distributing the fresh air output from inside the tube throughout the combustion chamber and mixing it thoroughly with the fuel. This effectively and completely combusts the exhaust gas, further improving combustion efficiency and completeness. By incorporating a limiting structure with two connecting gears and a limiting right-angle rod, the limiting right-angle rod on the first connecting gear is rotated and fitted into the arc-shaped limiting opening on the fixing block during subsequent equipment placement. This ensures the stability of the first connecting gear and further guarantees the stability and robustness of the two connecting gear structures, preventing malfunctions and enhancing the practicality and safety of the device, thus addressing the problems mentioned in the background art.

[0012] In a preferred embodiment, a limiting right-angle rod is embedded in the top of the first connecting gear, the bottom end of the limiting right-angle rod extends into the interior of the first connecting gear, and the limiting right-angle rod is made of an alloy material.

[0013] In a preferred embodiment, the limiting structure includes a fixing block, the side of which has an arc-shaped limiting opening, the bottom end face of which has recesses on the left and right sides, and the bottom end face of which has a fixing pivot.

[0014] In a preferred embodiment, a mounting base plate is rotatably sleeved at the bottom end of the fixed pivot, and top side plates are inlaid on both the left and right sides of the top of the mounting base plate. A fixing spring is embedded in the surface of the top side plate, and a fixing circular plate is embedded in one side of the fixing spring.

[0015] In a preferred embodiment, a connecting rod two is embedded inside the fixed circular plate, and an embedded post is embedded at the other end of the connecting rod two.

[0017] 1. This invention, by setting up an air intake assembly, a rotating assembly, and an oxidation tower, utilizes the cooperation of these components. First, the air pump is turned on, and fresh air from the outside is introduced into the combustion chamber inside the fixed oxidation tower through the air intake bend, a fixed circular pipe, and a connecting metal pipe.

This invention, by setting a fixing block, a notch, a second connecting rod, a fixing spring, and an embedded column, utilizes the initial state of the fixing spring being compressed, which allows it to drive the second connecting rod and one end of the embedded column to be embedded into the interior of the notch, thus completing the application of pressure and fixation. At the same time, the fixing block can be rotated laterally and vertically on the damping shaft at the top of the mounting base plate, ensuring that the fixing block can be opened when needed, increasing the flexibility of the device.

[0037] Working principle of the invention:

[0038] Step 1: First, the operator assembles all the components of the device normally, and then starts the device normally.

[0039] Step 2: First, the operator turns on the air pump 71, introducing fresh air from the outside through the intake bend 76, the fixed circular pipe 71, and the connecting metal pipe 72 into the combustion chamber 6 inside the fixed oxidation tower 1. Simultaneously, the drive motor 83 drives the drive shaft 84 to rotate on the side of the mounting bracket 81. The drive shaft 84 then drives the drive gear 85 to rotate, sequentially rotating the driven wheel 86 and the first connecting gear 88, until it rotates the second connecting gear 89. At this point, the second connecting gear 89 rotates the connecting pipe 74 inside it, which in turn rotates through the fixed circular pipe at its bottom. The pipe 71 and the connecting metal pipe 72 perform regular circular rotation, thereby distributing the fresh air output from the connecting metal pipe 72 throughout the combustion chamber 6 and fully mixing it with the fuel, thus effectively and completely burning the exhaust gas, further improving combustion efficiency and completeness. At the same time, when placing the equipment later, the limiting right angle rod 891 on the first connecting gear 88 is rotated and sleeved into the arc-shaped limiting port 92 on the fixing block 91 and locked in place, thereby ensuring the stability of the first connecting gear 88, further ensuring the stability and firmness between the two connecting gear structures, and preventing malfunctions.

[0040] Step 3: First, the operator shuts down the device normally. Then, the operator checks whether the fixing between the various components of the device is normal. Then, the operator replaces and repairs the aging and severely worn parts inside the device.

[0041] 4. In the above scheme, by setting up an air intake assembly, a rotating assembly, and an oxidation tower, and utilizing the cooperation of these components, the air pump is first turned on, and fresh air from the outside is introduced into the combustion chamber inside the fixed oxidation tower through the air intake bend, a fixed circular pipe, and a connecting metal pipe. At the same time, the drive motor drives the drive shaft to rotate on the side of the mounting frame, which in turn drives the drive gear to rotate, and then drives the driven wheel, the first connecting gear, and finally the second connecting gear to rotate. At this time, the second connecting gear drives the connecting pipe inside to rotate, and then the fixed circular pipe and the connecting metal pipe at its bottom end perform regular circular rotation, thereby distributing the fresh air output from the connecting metal pipe throughout the combustion chamber and mixing it fully with the fuel, thus effectively and completely burning the exhaust gas, further improving combustion efficiency and completeness.

[0042] By setting up a limiting structure with two connecting gears and a limiting right-angle rod, when the equipment is placed later, the limiting right-angle rod on the first connecting gear is rotated and sleeved into the arc-shaped limiting opening on the fixed block and locked in place. This ensures the stability of the first connecting gear, further ensuring the stability and firmness between the two connecting gear structures, avoiding malfunctions, and further improving the practicality and safety of the device.
