[0030] 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.
[0031] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a waste gas acid-base balance pH neutralization tank with dual stirring function, including a tank body 1 for containing the waste gas to be treated and the reagents for acid-base neutralization reaction, providing a relatively closed and stable space environment for the reaction. The tank body 1 is made of stainless steel. A mounting cover 2 is provided on the upper part of the tank body 1 to seal the top opening of the tank body 1 and prevent waste gas leakage. A drive motor 3 is fixedly connected to the upper part of the mounting cover 2 to provide power for the stirring process. This technology is prior art and will not be described in detail. A planetary gear set 4 is provided inside the mounting cover 2. The output shaft of the drive motor 3 is fixedly connected to the main gear in the planetary gear set 4. This technology is prior art and will not be described in detail. A gas supply pipe 7 is fixedly connected to the upper part of the mounting cover 2. Two sets are provided to transport and discharge the waste gas. A stirring mechanism is provided at the lower part of the planetary gear set 4. The stirring mechanism includes a stirring component and a spraying component.
[0032] Reference Figure 2 - Figure 4The stirring assembly includes a rotating rod 51, which is connected to the main gear in the planetary gear set 4 and is directly driven by the drive motor 3. It can drive multiple sets of stirring blades 52 to rotate. The rotating rod 51 is fixedly connected to the lower side of the output shaft of the drive motor 3. The stirring blades 52 are fixedly connected to the outside of the rotating rod 51. The blades of the stirring blades 52 are inclined and rotate under the drive of the rotating rod 51 to stir the waste gas and the agent, increase the contact area and collision opportunities, promote the full reaction of acidic or alkaline components in the waste gas with the agent, and improve the neutralization efficiency. The outside of the rotating rod 51 is rotatably connected to a connecting cylinder 53, which is rotatably connected to the secondary gear in the planetary gear set 4. Under the action of the planetary gear set 4, the connecting cylinder 53 can be driven to rotate in the opposite direction, thereby driving the fixed part 54 to rotate. The output end of the planetary gear set 4 is rotatably connected to the upper interior of the connecting cylinder 53.
[0033] Furthermore, a fixing member 54 is fixedly connected to the lower outer side of the connecting cylinder 53 to fix the turbulence vane 56 and the sleeve 55, and to transmit the rotational motion of the connecting cylinder 53 to the turbulence vane 56, so that the turbulence vane 56 generates a lateral turbulence effect in the tank body 1. By coordinating with the vertical stirring of the stirring blade 52, a dual stirring effect on the waste gas and the reagent is achieved, further improving the mixing degree of the materials and accelerating the acid-base neutralization reaction process. The lower part of the stirring blade 52 is fixedly connected to a sleeve 55. Multiple sets of sleeves 55 are provided, and multiple sets of sleeves 55 are respectively set on the upper and lower sides of the fixing member 54 for connecting the fixing member 54. The sleeves 55 are rotatably connected to the outside of the rotating rod 51. Multiple sets of fixing members 54 and sleeves 55 are provided. A turbulence blade 56 is fixedly connected on the opposite side of the multiple sets of fixing members 54. Multiple sets of turbulence blades 56 are provided, and the multiple sets of turbulence blades 56 are inclined. The multiple sets of turbulence blades 56 are arranged in a circumferential array with the center point of the fixing member 54, which generates a lateral turbulence effect on the waste gas in the tank 1.
[0034] Reference Figure 1 - Figure 3 The spraying assembly includes a delivery pipe 6, which is fixedly connected inside the mounting cover 2. A nozzle is located at the lower part of the delivery pipe 6. The delivery pipe 6 serves as a channel for transporting the neutralizing agent from the outside into the tank 1. The agent is then evenly sprayed into the exhaust gas inside the tank 1 through the lower nozzle, ensuring that the agent is fully dispersed in the exhaust gas and reacts fully with the acidic or alkaline components in the exhaust gas. This provides the necessary reactants for the acid-base neutralization reaction, ensuring its smooth progress. A sealing ring is located at the lower part of the mounting cover 2, filling the gap between the mounting cover 2 and the tank 1 to prevent exhaust gas from leaking through the gap during operation, ensuring good sealing of the device.
[0035] Reference Figure 2 , Figure 3 and Figure 5The tank body 1 is equipped with a maintenance component, which includes a limit pin 81. The limit pin 81 is fixedly connected to the lower part of the mounting cover 2, and multiple sets are provided. The limit pin 81 has a slot 82 on its outer side. The limit pin 81 is inserted into the limit block 84 through the slot 82 to ensure the stable installation of the mounting cover 2 on the tank body 1, and to prevent the mounting cover 2 from being displaced or loosened due to vibration or other external forces, thus ensuring the sealing performance and overall structural stability of the device. The tank body 1 is rotatably connected to a limit ring 83. When it is necessary to maintain the stirring mechanism, the limit block 84 can be disengaged from the slot 82 by rotating the limit ring 83, thereby releasing the restriction on the mounting cover 2. This makes it convenient to remove the mounting cover 2 together with the stirring mechanism for maintenance or repair, improving the maintenance convenience and operability of the device. The front side of the limit ring 83 is fixedly connected to a protrusion 85.
[0036] Furthermore, a limiting block 84 is fixedly connected to the inner side of the limiting ring 83. The limiting block 84 is inserted into the slot 82. The protrusion 85 is fixedly installed to the tank body 1 by bolts 86. Removing the bolts 86 can separate the protrusion 85 from the tank body 1, thereby allowing the limiting ring 83 to rotate and realize the unlocking operation of the mounting cover 2, which provides operational convenience for the maintenance of the device. The lower right side of the limiting block 84 is set as an inclined surface, which makes it easy for the limiting block 84 to slide smoothly into the slot 82 when the mounting cover 2 is lowered during the installation process, realizing automatic alignment and installation, and improving the installation efficiency and convenience of the device.
[0037] Working principle: When in use, the drive motor 3 is started, and its output shaft drives the main gear of the planetary gear set 4 to rotate. The rotating rod 51 starts to rotate under the direct drive of the drive motor 3, which in turn drives the stirring blade 52 fixed on the outside of the rotating rod 51 to rotate. Since the blades of the stirring blade 52 are inclined, they can effectively stir the waste gas and the agent vertically during the rotation, which promotes the waste gas and the agent to mix fully in the vertical direction, increases the contact area and collision opportunities between the two, effectively promotes the full reaction of acidic or alkaline components in the waste gas with the agent, and greatly improves the neutralization efficiency.
[0038] Meanwhile, the power output of the planetary gear set 4 causes the connecting cylinder 53 to rotate in the opposite direction outside the rotating rod 51. The fixing part 54 fixed on the lower outer side of the connecting cylinder 53 rotates with the rotation of the connecting cylinder 53 and transmits the rotational motion to the turbulence vane 56. Driven by the fixing part 54, a lateral turbulence effect is generated in the tank 1. Through the lateral turbulence and the vertical stirring of the stirring vane 52 working together, the waste gas and the reagent form a complex three-dimensional flow state inside the tank 1, further breaking the possible stratification of materials, improving the degree of mixing of materials, accelerating the process of acid-base neutralization reaction, ensuring that the waste gas can be fully and efficiently treated, and making the discharged gas meet environmental protection standards.
[0039] When maintenance of the stirring mechanism is required, first remove the bolt 86 between the protrusion 85 and the tank 1 to separate the protrusion 85 from the tank 1. Then rotate the limiting ring 83. Since the lower right side of the limiting block 84 inside the limiting ring 83 is set as an inclined surface, during the rotation, the limiting block 84 can smoothly disengage from the slot 82 outside the limiting pin 81, thereby releasing the restriction on the mounting cover 2. At this time, the mounting cover 2 can be easily and quickly removed together with the stirring mechanism for maintenance or repair. The operation is simple and efficient.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
