Detailed Implementation

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a coupling treatment device for ink waste liquid VOC, including a base plate 1. The upper end surface of the base plate 1 is respectively provided with a treatment box 2, a storage box 14 and a pressure pump 18. The storage box 14 is connected to the interior of the treatment box 2 through a material pipeline. A delivery pump 17 is installed on the material pipeline. The output end of the pressure pump 18 is connected to the interior of the treatment box 2 through an air pipe.

[0025] The base plate 1 serves as the installation foundation for the entire device, providing a stable mounting platform for the treatment tank 2, storage tank 14, and pressurization pump 18, ensuring the overall structural stability of the equipment. The treatment tank 2 can hold waste liquid and treat VOCs within it. The pressurization pump 18 injects air into the treatment tank 2, increasing the internal air pressure and promoting VOC volatilization.

[0026] As shown in the figure, the treatment tank 2 is equipped with a stirring mechanism for agitating the waste liquid. The stirring mechanism includes a rotating rod 4 rotatably connected inside the treatment tank 2, and several blades 5 are fixedly connected to the rotating rod 4. A drive motor 3 is installed at the bottom of the treatment tank 2 via a flange, and the output end of the drive motor 3 is fixedly connected to the bottom end of the rotating rod 4. Each blade 5 is inclinedly arranged on the rotating rod 4, and each blade 5 has several openings 6.

[0027] When in use, the stirring mechanism can drive the rotating rod 4 and the blade 5 to rotate via the drive motor 3. The inclined design and the opening 6 can create turbulence in the waste liquid in the treatment tank 2, which enhances the mixing effect and VOC volatilization efficiency.

[0028] As shown in the figure, a top plate 9 is detachably installed on the top of the processing box 2. An annular support plate 13 is fixedly connected inside the processing box 2. The top plate 9 is installed above the annular support plate 13, and two hanging plates 12 are fixedly connected to the top plate 9. An adsorption processing mechanism is provided on the top plate 9. The adsorption processing mechanism includes several hanging rods 10 fixedly connected to the top plate 9, and each hanging rod 10 is fitted with an adsorption sleeve 11.

[0029] It should be noted that the rod 10 is made of breathable material, and the gas treated by the adsorption sleeve 11 can be output to the outside through the rod 10.

[0030] The annular support plate 13 provides a stable installation foundation for the top plate 9, and the hanging plate 12 can assist in hoisting, facilitating the disassembly and maintenance of the top plate 9. The adsorption sleeve 11 is made of adsorption materials such as activated carbon, which can efficiently capture gaseous VOCs to ensure that the exhaust gas meets the standards. It is installed on the hanging rod 10 for easy replacement.

[0031] As shown in the figure, an isolation mesh plate 7 and a reinforcing shell 8 are fixedly connected inside the processing box 2, with the reinforcing shell 8 positioned above the isolation mesh plate 7. The reinforcing shell 8 is a Venturi tube structure, which can increase the gas flow rate and improve processing efficiency.

[0032] As shown in the figure, a discharge pipe 19 is fixedly connected to the treatment tank 2, and a control valve 20 is installed on the discharge pipe 19. A cover plate 16 is hinged to the upper end face of the storage tank 14, and a level gauge 15 is installed on the storage tank 14. The discharge pipe 19 and the control valve 20 can discharge the treated liquid in the treatment tank 2 to the outside.

[0033] The working principle of this utility model is as follows: During use, the ink waste liquid can be stored in the storage tank 14. The transfer pump 17 can then send the ink waste liquid into the treatment tank 2 for processing. During this process, the drive motor 3 drives the rotating rod 4 and the inclined blade 5 to rotate at high speed, creating turbulence in the waste liquid. This promotes thorough mixing of the treatment agent and the waste liquid, accelerates the chemical reaction, and enhances the evaporation efficiency of volatile organic compounds. Furthermore, starting the pressure pump 18 injects air into the bottom of the treatment tank 2 through an air pipe. With the cooperation of the reinforced housing 8, this can form… The high-speed airflow increases the air pressure inside the chamber, forcing VOCs to transfer from the liquid phase to the gas phase. On the other hand, the combined effect of the airflow and stirring creates intense turbulence between the gas and liquid phases, enhancing the desorption process of VOCs. The volatilized gaseous VOCs can rise to the top of the treatment chamber 2 and come into contact with the adsorption sleeve 11. The adsorption sleeve 11 is filled with activated carbon or other adsorption materials, which can efficiently capture VOCs and ensure that the exhaust gas meets the standards. The treated purified liquid can be discharged through the discharge pipe 19. The adsorption sleeve 11 that is saturated can be replaced through the detachable top plate 9, making maintenance convenient.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
