Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology, specifically to an industrial waste gas scrubbing tower for industrial waste gas treatment. Background Technology

[0002] Among environmental pollution sources, industrial organic waste gas is one of the most important sources. These waste gases include carbon dioxide, carbon disulfide, carbon monoxide, soot, and industrial dust, which pollute the air when released into the atmosphere. These substances enter the human body through the respiratory tract via various routes; some cause direct harm, while others accumulate and can further endanger human health. A waste gas scrubbing tower is a commonly used waste gas treatment device. It uses an absorbent liquid to contact the waste gas and, through mass transfer, intercepts pollutants in the waste gas into the absorbent liquid, thereby reducing the concentration of pollutants in the waste gas.

[0003] A search revealed that Chinese utility model patent CN213824158U discloses an industrial waste gas scrubbing tower for industrial waste gas treatment. The tower includes a scrubbing tower body, a stirring rod fitted to the bottom of the inner wall of the body, a water storage tank at the bottom of the body, an air inlet pipe connected to one side of the water storage tank, a first filter screen fixedly installed inside the body, a scrubbing chamber inside the body, inclined plates fixedly installed at the bottom of the inner walls on both sides of the scrubbing chamber, a spray pipe fixedly installed on the inner wall of the chamber, a nozzle fixedly installed at the bottom of the spray pipe, a packing layer fixedly installed on the inner wall of the chamber, a feed pipe connected to one side of the packing layer, and a demister fixedly installed at the top of the inner wall of the chamber. This device uses a fan to draw waste gas into the water storage tank, and the liquid in the tank adsorbs impurities from the waste gas. However, in actual use, the accumulation of impurities in the liquid reduces the flow efficiency, requiring replacement of the liquid. After replacement, residual impurities remain in the water storage tank, making cleaning difficult. Utility Model Content

[0014] Please see Figure 1-5An industrial waste gas scrubbing tower for industrial waste gas treatment includes a filter box 1, an outlet box 2 fixedly connected to the top of the filter box 1, a conical filter cylinder 3 fixedly connected inside the filter box 1, and a mounting plate 4 fixedly connected inside the filter box 1. The top of the mounting plate 4 has multiple filter openings, each containing a filter screen 5. A first motor 6 is fixedly connected to the top of the mounting plate 4, and a rotating shaft 7 is fixedly connected to the output end of the first motor 6. The bottom end of the rotating shaft 7 extends to the bottom end of the conical filter cylinder 3. A circular guide plate 8 is fixedly connected to the bottom end inside the filter box 1. Multiple rotating plates 9 are fixedly connected to the outer wall of the rotating shaft 7, and cleaning brushes 10 are fixedly connected to the ends of the rotating plates 9 that are furthest from each other. A connecting plate 11 is fixedly connected to one end of the filter box 1, and an exhaust fan 12 is fixedly connected to one end of the connecting plate 11. An air inlet pipe 13 is fixedly connected to the air inlet end of the exhaust fan 12, and an air outlet pipe 14 is fixedly connected to the air outlet end of the exhaust fan 12. The other end of the air outlet pipe 14 extends into the interior of the filter box 1, where the filter box 1 is filled with filter solution. Drainage pipe 15 and water inlet pipe 16 are fixedly installed on the outer wall of filter box 1. When the exhaust fan 12 is started, the industrial waste gas is drawn into the interior of filter box 1. The industrial waste gas separates impurities inside the filter solution. As the gas rises, it passes through the conical filter cylinder 3 and is intercepted a second time. After rising, the gas passes through the filter screen 5, forming a third filtration of the gas, thus completing the washing and filtration of the industrial waste gas. When the first motor 6 is powered on, the output end of the first motor 6 drives the rotating shaft 7 to rotate. During the rotation of the rotating shaft 7, the rotating plate 9 and the cleaning brush 10 rotate, cleaning the bottom of the conical filter cylinder 3 and the top of the annular guide block. When the filter solution is discharged, the phenomenon of impurity residue is greatly avoided.

[0015] Preferably, one end of the exhaust box 2 has a pull-out opening, and both ends of the interior of the exhaust box 2 have sliding grooves. A movable slider 17 is slidably connected inside each of the two sliding grooves. A support drawer 18 is fixedly connected between the two movable sliders 17. The bottom of the support drawer 18 has multiple air inlets, and the top of the exhaust box 2 has multiple air outlets. One end of the support drawer 18 is fixedly connected to a push-pull handle 19. By manually filling the support drawer 18 with filter material and allowing gas to pass through the filter material, the washing and filtering effect on industrial waste gas is further improved. Please see Figure 3 Multiple air inlets and outlets are equipped with filter screens 20, which further improves the filtration effect of exhaust gas. Stable feet 21 are fixedly installed at the four corners of the bottom of the filter box 1 to support the overall device and increase the height of the overall device. Please see Figure 1An observation window 22 is provided at one end of the filter box 1. The inside of the observation window 22 is fixedly installed with curved tempered glass, which allows the staff to more intuitively view the filter solution inside the filter box 1.

[0016] The first motor 6 is a commercially available device known to those skilled in the art. We are simply using it here without making any structural or functional improvements, and we will not go into detail about it here.

[0017] In summary, when this industrial waste gas scrubbing tower is in use, the exhaust fan 12 first draws the industrial waste gas into the filter box 1. Impurities in the industrial waste gas are separated within the filter solution. The rising gas passes through the conical filter cylinder 3, where impurities are further intercepted. After rising further, the gas passes through the filter screen 5, forming a third filtration. Filter material is manually added to the carrying drawer 18, and the gas passes through the filter material, completing the scrubbing and filtration of the industrial waste gas. When the first motor 6 is powered on, its output drives the rotating shaft 7 to rotate. During the rotation of the rotating shaft 7, the rotating plate 9 and cleaning brush 10 rotate, cleaning the bottom of the conical filter cylinder 3 and the top of the annular guide block. This greatly reduces the possibility of impurities remaining when the filter solution is discharged.

[0018] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
