Detailed Implementation

[0015] 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.

[0016] Please see Figures 1-5This utility model provides a technical solution, including a purification box 1. Three partition plates 2 are connected inside the purification box 1, dividing the interior into four cavities. A treatment liquid tank 3 is connected to the top of the purification box 1, and a liquid inlet pipe 4 is connected to the top of the treatment liquid tank 3. Two liquid inlet pipes 5 are connected to the lower half of one side of the treatment liquid tank 3. Multiple inlet pipes 6 are connected to one side of each of the two liquid inlet pipes 5, extending into the interior of the purification box 1 below the partition plates 2. Multiple high-pressure nozzles 7 are connected to the lower surface of each inlet pipe 6. Four mounting pipes 8 are connected to the surfaces of the three partition plates 2. A one-way valve 9 is installed inside the pipe 8. Four drain pipes 12 are installed on the rear side of the purification box 1. The four drain pipes 12 are respectively installed in the lower half of the four cavities inside the purification box 1. An electric butterfly valve 13 is installed on the surface of each of the four drain pipes 12. Two exhaust pipes 14 are installed on the upper half of the rear side of the purification box 1. One end of the exhaust pipe 14 extends into the uppermost cavity inside the purification box 1. A support frame 15 is installed on one side of the purification box 1. A high-pressure exhaust fan 16 is installed at the top of the support frame 15. An air inlet pipe 17 is installed at the output end of the high-pressure exhaust fan 16. The air inlet pipe 17 extends into the lowermost cavity inside the purification box 1.

[0017] A rotating shaft 19 is rotatably mounted inside the intake pipe 17. Three turbine fans 18 are connected to the surface of the shaft 19 inside the intake pipe 17. The top of the shaft 19 extends into the uppermost cavity inside the purification chamber 1. Agitator blades 20 are connected to the surface of the shaft 19 within each of the four cavities. Their function is to drive the rotating shaft 19 to rotate through the rotation of the turbine fans 18, thereby allowing the agitator blades 20 to thoroughly agitate and mix the gas and the treated liquid within the four cavities, increasing the contact area between the exhaust gas and the treated liquid, and improving purification efficiency. Simultaneously, the rotation of the turbine fans 18 also generates a certain negative pressure effect, which helps the exhaust gas enter the purification chamber 1 more smoothly, further improving the overall operating efficiency of the device.

[0018] A stabilizing frame 21 is connected to the surface of the end of the infusion pipe 6 away from the liquid inlet pipe 5, and the top of the stabilizing frame 21 is connected to the bottom of the partition plate 2. Its function is to effectively fix the position of the infusion pipe 6 and prevent it from shaking or shifting due to the impact force generated by the liquid flow when the high-pressure nozzle 7 is working. This not only ensures the stability of the infusion pipe 6, but also ensures the uniformity and accuracy of the treatment liquid sprayed by the high-pressure nozzle 7, thereby further improving the effect of waste gas purification.

[0019] A transparent graduated plate 22 is connected to one side of the treatment liquid tank 3. Its function is to allow operators to visually observe the liquid level in the treatment liquid tank 3, facilitating timely replenishment of the treatment liquid and preventing interruptions or efficiency reductions in the purification process due to low liquid levels. The design of the transparent graduated plate 22 not only improves the reliability of the device operation but also simplifies daily maintenance, making operation more convenient and efficient.

[0020] An activated carbon plate 23 and an exhaust fan 24 are connected to the inside of the exhaust pipe 14, and the activated carbon plate 23 and exhaust fan 24 are arranged side to side. The activated carbon plate 23 effectively adsorbs harmful substances and odors in the exhaust gas, further purifying the gas and ensuring that the discharged gas meets environmental standards. The exhaust fan 24 generates airflow through rotation, accelerating the gas discharge process and preventing gas stagnation inside the purification chamber 1, thereby improving the overall purification efficiency. The synergistic effect of both not only optimizes the exhaust performance of the device but also significantly enhances the thoroughness of exhaust gas treatment, providing a reliable guarantee for environmental protection.

[0021] A separator cylinder 10 is connected to the surface of the separator plate 2 above the one-way valve 9. The upper half of the separator cylinder 10 has multiple through holes 11, which allow for uniform gas distribution between different cavities. When gas enters the separator cylinder 10 from the lower cavity through the one-way valve 9, the through holes 11 allow the gas to flow into the upper cavity in a more dispersed manner, avoiding uneven purification caused by excessively concentrated airflow. This structure not only improves the contact efficiency between the gas and the treatment liquid but also further optimizes the stability and effectiveness of the purification process. Furthermore, the separator cylinder 10 effectively prevents liquid backflow, ensuring that the purification process within each cavity operates independently and efficiently.

[0022] The bottom of the purification chamber 1 is connected to four support legs 25, which are arranged in a rectangular pattern. This rectangular arrangement provides stable support for the entire purification unit, ensuring its stability during operation and preventing tipping or displacement due to vibration or external factors. This structure not only enhances the overall stability of the device but also facilitates installation and adjustment in different locations. Furthermore, the rational layout of the support legs 25 provides sufficient space at the bottom of the device, facilitating future maintenance and cleaning, further improving the practicality and ease of operation of the equipment.

[0023] Working Principle: Exhaust gas is introduced into the lowermost cavity of the purification chamber 1 via the high-pressure exhaust fan 16 and the intake pipe 17. During the intake process, the turbine fan 18 is driven to rotate by the airflow, which drives the rotating shaft 19 and the stirring blades 20 to operate synchronously. The stirring blades 20 thoroughly mix the gas and the treatment liquid in the four cavities, increasing the contact area between the two to improve the purification effect. At the same time, the liquid in the treatment liquid tank 3 is replenished through the liquid filling pipe 4 and distributed to multiple liquid delivery pipes 6 through the liquid flow pipe 5, and finally evenly sprayed out by the high-pressure nozzles 7 to react with the exhaust gas. The separator cylinder 10 on the separator plate 2 achieves uniform gas distribution in different cavities through its surface through holes 11, avoiding the problem of uneven local purification. The one-way valve 9 ensures that the gas flows along a predetermined path and prevents backflow. After multi-stage purification, the gas enters the uppermost cavity. When it passes through the exhaust pipe 14, the activated carbon plate 23 further adsorbs residual harmful substances, while the exhaust fan 24 accelerates the gas discharge. Waste liquid generated during the purification process is discharged through drain pipe 12, and electric butterfly valve 13 controls the timing of discharge to ensure orderly waste liquid discharge. A transparent scale plate 22 displays the liquid level in the treatment liquid tank 3 in real time, facilitating timely replenishment of the treatment liquid by operators and ensuring the continuity of the purification process. The entire device relies on support legs 25 for stable operation, while also facilitating maintenance and cleaning.
