Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment and exhaust gas purification technology, and in particular to a non-powered decentralized air purification device. Background Technology

[0002] During operation, wastewater treatment plants generate waste gas containing harmful components such as hydrogen sulfide and volatile organic pollutants. If this waste gas is directly discharged, it will pollute the surrounding atmospheric environment and endanger the health of the staff.

[0003] In the existing process of treating waste gas, the waste gas tank is covered and an outlet is set up. The outlet is connected to an air purification box to purify the waste gas generated in the waste gas tank before it is discharged. However, during the use of the air purification box, multiple purification modules inside need to be replaced and maintained frequently. When replacing them, the air purification box's sealed environment is damaged, causing a small amount of waste gas to escape and cause air pollution. At the same time, the purification modules are sealed and embedded in the air purification box, making them inconvenient to remove, resulting in low maintenance efficiency.

[0004] Therefore, a non-powered decentralized air purification device has been developed that allows for easy removal and replacement of multiple purification modules and maintains a sealed state during maintenance to prevent exhaust gas from overflowing and causing pollution. Utility Model Content

[0005] To overcome the shortcomings of existing wastewater tank exhaust gas purification devices, such as the disruption of the air purification box's sealed environment during purification module replacement leading to a small amount of exhaust gas leakage and causing air pollution, and the inconvenience of removing the purification modules due to their sealed embedding within the air purification box resulting in low maintenance efficiency, this utility model provides a non-powered decentralized air purification device that allows for easy removal and replacement of multiple purification modules while maintaining a sealed state during maintenance to prevent exhaust gas leakage and pollution.

Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0020] A non-powered, decentralized air purification device, such as Figures 1-5 As shown, the system includes an installation frame 1, an opening / closing door 2, a pretreatment plate 3, a diaphragm 4, an oxidation desulfurization module 5, a catalytic oxidation module 6, a biocatalyst module 7, a rotating plate 8, a gear 9, a torsion spring 10, a rack 11, a pressing frame 12, an ejection frame 13, a guide rod 14, and a telescopic spring 15. The opening / closing door 2 is slidably connected to the front of the installation frame 1, and the door 2 has a handle groove for easy pulling. The air inlet of the installation frame 1 has a conical structure for easy air collection. The pretreatment plate 3 is slidably engaged with the lower part of the installation frame 1, and the diaphragm 4 is slidably engaged with the lower part of the installation frame 1, located above the pretreatment plate 3. The oxidation desulfurization module 5 is slidably engaged with the upper part of the installation frame 1, and the catalytic oxidation module 6 is also slidably engaged with the upper part of the installation frame 1, located above the oxidation desulfurization module 5. The upper part of the installation frame 1 is also slidably engaged with... The system includes a biocatalyst module 7, located above the catalytic oxidation module 6. A rotating plate 8 is rotatably connected to the lower part of the mounting frame 1. A gear 9 is connected to the left side of the rotating plate 8. A torsion spring 10 connects the rotating plate 8 and the mounting frame 1. A rack 11 is connected to the lower side of the opening and closing door 2, meshing with the gear 9. A pressing frame 12 is slidably connected to the left side of the mounting frame 1. The pressing frame 12 has an inclined guide groove to guide the ejector frame 13. Two guide rods 14 are connected to the rear side of the interior of the mounting frame 1. The ejector frame 13 is slidably connected between the guide rods 14. A telescopic spring 15 connects the guide rods 14 to the ejector frame 13. The ejector frame 13 slides with the pressing frame 12. The pressing frame 12 contacts the opening and closing door 2. A limit frame is provided on the opening and closing door 2 to limit the pressing frame 12 and prevent accidental activation.

[0021] When using this utility model, firstly, according to the distribution location of each sewage tank, the air inlet end of the mounting frame 1 of each device is connected one-to-one with the air outlet of the corresponding sewage tank to achieve a decentralized layout, avoiding the leakage risk of centralized waste gas transportation. The waste gas is introduced into the device without power through the conical air inlet at the bottom of the mounting frame by the slight positive pressure in the sewage tank, without the need for additional power equipment, which is energy-saving and environmentally friendly. The waste gas enters from the bottom of the mounting frame 1, passes through the pretreatment plate 3 for particulate matter filtration, the diaphragm 4 for preliminary separation, and then passes through the oxidation desulfurization module. 5. Hydrogen sulfide is removed, volatile organic pollutants are degraded by the catalytic oxidation module 6, and finally, after deep purification by the biocatalyst module 7, the waste gas is discharged without power from the top of the mounting frame under its own pressure difference, realizing multi-stage purification of waste gas without power. When the purification module needs to be replaced or maintained, the operator holds the handle of the opening and closing door 2 and slides the opening and closing door 2 to the right. The opening and closing door 2 drives the rack 11 on the lower side to move to the right. The rack 11 meshes with the gear 9, driving the gear 9 to rotate, which in turn drives the rotating plate 8 to rotate, and the torsion spring 10 is twisted. This seals the air inlet with the rotating plate 8. Simultaneously, after the opening / closing door 2 slides upwards, it no longer presses against the pressing frame 12. At this point, the operator presses the pressing frame 12 downwards. Through the sliding engagement between the pressing frame 12 and the ejector frame 13, the ejector frame 13 is pushed forward along the guide rod 14. The telescopic spring 15 is stretched. As the ejector frame 13 moves forward, it simultaneously pushes forward the pretreatment plate 3, diaphragm 4, oxidation desulfurization module 5, catalytic oxidation module 6, and biocatalyst module 7 within the mounting frame 1, facilitating quick removal and replacement by the operator. After replacement, release the pressing bracket 12. Under the reset action of the telescopic spring 15, the push-out bracket 13 slides backward to reset. Release the opening and closing door 2. Under the reset action of the torsion spring 10, the gear 9 rotates in the opposite direction, driving the rack 11 and the opening and closing door 2 to slide downward, closing the mounting frame 1 and restoring the sealed state of the device. At the same time, the opening and closing door 2 limits the pressing bracket 12 to prevent accidental contact. This allows for easy removal and replacement of multiple purification modules and maintains a sealed state during maintenance to prevent exhaust gas from overflowing and causing pollution.
