[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figures 1 to 3 The utility model provides an embodiment: an automatic alkali-adding purification and discharge device for acid mist condensation, comprising a base plate 1, the outside of which is fixedly connected to an alkali liquid tank 2 for storing alkaline liquid. In order to achieve an efficient spray purification function, a spray tower 3 is also fixedly connected to the outside of the base plate 1. The spray tower 3 is designed to be cylindrical and has a multi-layer spray device inside. The outside of the alkali liquid tank 2 is fixedly connected to a drive assembly that provides power, and the drive assembly includes a motor 4 and a stirring rod 5. The motor 4 is fixed to the outside of the alkali liquid tank 2 by a bracket, and the stirring rod 5 extends into the inside of the alkali liquid tank 2 to stir the alkali liquid to maintain its uniformity. In order to accurately control the amount of alkali added, a metering pump 6 is fixedly connected to the outside of the alkali liquid tank 2, and the metering pump 6 is connected to the alkali delivery pipe 7.

[0032] The alkali delivery pipe 7 is made of corrosion-resistant material to ensure long-term stable operation. The other end of the alkali delivery pipe 7 is fixedly connected to a connecting pipe 8, which transports the alkali solution to multiple spray pipes 9. The spray pipes 9 are arranged horizontally, and multiple nozzles 10 are fixedly connected to the bottom. These nozzles 10 can evenly spray the alkali solution into the spray tower 3 to form fine droplets so that they can fully contact with the acidic gas and undergo a neutralization reaction. In addition, multiple activated carbon plates 11 are fixedly connected to the interior of the alkali solution tank 2. These activated carbon plates 11 are used to adsorb residual acidic gases and odors, further improving the purification effect. The activated carbon plates 11 are made of high-efficiency activated carbon material and have a large specific surface area and good adsorption properties.

[0033] Reference Figures 2 to 4 The outside of the spray tower 3 is fixedly connected to a delivery pipe 12, which is made of corrosion-resistant material and is used to transport the treated gas to the purifier 13. The outside of the base plate 1 is fixedly connected to the purifier 13, and the purifier 13 is equipped with high-efficiency filter material to further remove impurities and odors in the gas. The top of the purifier 13 is fixedly connected to a discharge pipe 14, which is designed to be circular and is used to safely discharge the purified gas into the atmosphere. The outside of the spray tower 3 is also fixedly connected to a docking pipe 15, which is made of stainless steel and has good corrosion resistance and sealing performance. The inside of the docking pipe 15 is fixedly connected to a limit ring 16, which is used to limit the movement range of the connecting block 18. A spring 17 is provided on the outside of the limit ring 16. The spring 17 has a certain elasticity and can provide a buffering effect during the operation of the device. The outside of the spring 17 is fixedly connected to a connecting block 18, which is made of wear-resistant material and can slide inside the docking pipe 15.

[0034] The connecting block 18 is fixedly connected to the outside of a sealing ring 19. The sealing ring 19 is made of a high-temperature-resistant and corrosion-resistant rubber material to ensure the sealing performance of the device. The sealing ring 19 is fixedly connected to the outside of a fixing rod 20, which is used to fix the connecting pipe 15 to other components. The inside of the connecting pipe 15 is also fixedly connected to a limit plate 21, which is used to limit the movement range of a ball 22. The outside of the connecting pipe 15 is slidably connected to a ball 22, which can roll inside the connecting pipe 15 to achieve relative movement between the connecting pipe 15 and the connecting block 18. The outside of the connecting pipe 15 is also fixedly connected to a limit block 23, which is used to limit the movement range of a sliding ring 25. The outside of the limit block 23 is fixedly connected to a spring 24. The spring 24 has a certain degree of elasticity and can provide a buffering effect during the operation of the device. The outside of the spring 24 is fixedly connected to a sliding ring 25. The sliding ring 25 can slide outside the connecting pipe 15 to achieve relative movement between the connecting pipe 15 and the limit block 23.

[0035] Working principle: First, acidic gas is introduced into the spray tower 3, and then the motor 4 in the drive assembly is started, and the alkaline liquid in the alkali liquid tank 2 is stirred by the stirring rod 5 to maintain its uniformity. Then, the metering pump 6 accurately controls the amount of alkali added according to actual needs, and transports the alkaline liquid to the alkali pipe 7. The alkali pipe 7 transports the alkaline liquid to the connecting pipe 8, and the connecting pipe 8 distributes the alkaline liquid to multiple spray pipes 9. The nozzle 10 at the bottom of the spray pipe 9 evenly sprays the alkaline liquid in the spray tower 3 to form fine droplets. These droplets fully contact with the acidic gas and undergo a neutralization reaction to achieve the purpose of purifying the acidic gas. At the same time, the activated carbon plate 11 inside the alkali liquid tank 2 can absorb residual acidic gas and odor, further improving the purification effect. Finally, the treated gas is further filtered and purified through the purifier 13, and finally safely discharged into the atmosphere through the discharge pipe 14;

[0036] Inside the butt joint pipe 15, a limit ring 16 is fixedly connected to limit the range of movement of the connecting block 18. A spring 17 is provided on the outside of the limit ring 16, and its elasticity can provide the necessary buffering effect during the operation of the device. The connecting block 18 slides inside the butt joint pipe 15, and a sealing ring 19 is fixedly connected to its outside. The outside of the sealing ring 19 is also fixedly connected to a fixing rod 20. At the same time, a limit block 23 is also fixedly connected to the outside of the butt joint pipe 15. It works together with the spring 24 and allows the sliding ring 25 to slide outside the butt joint pipe 15, thereby realizing the relative movement between the butt joint pipe 15 and the limit block 23. When the pipe butt joint is completed, the self-locking process It also starts. First, the connecting block 18 moves to the preset position under the action of spring 17. At this time, the sealing ring 19 is close to the fixing rod 20, forming a preliminary sealing state. Then the ball 22 rolls under the restriction of the limit plate 21, pushing the connecting block 18 to continue to slide forward until it is completely embedded in the limit ring 16. At this time, the sealing ring 19 is subjected to greater pressure, forming a tighter sealing effect. Finally, the sliding ring 25 slides under the restriction of the limit block 23, so that the fixing rod 20 is tightly fitted with the docking tube 15, completing the final self-locking process.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
