Description

Technical Field

[0001] The utility model relates to the field of waste gas treatment, in particular to a combined high-efficiency biological waste gas purification device. Background Art

[0002] Biological waste gas usually refers to the gaseous emissions containing organic matter generated during the biological treatment process. These waste gases may come from various biological treatment facilities, such as aerobic digesters in sewage treatment plants, composting facilities, biological filters, etc. In these facilities, microorganisms decompose organic substances to treat sewage or waste, and gases such as oxygen, carbon dioxide, and methane will be generated during the process.

[0003] After retrieval, an integrated combined waste gas purification device is disclosed in the publication number: CN212701017U, which includes a device main body. The device main body includes a primary purification chamber, a secondary purification chamber, and a disinfection and sterilization chamber. The inner side walls of the device main body are symmetrically provided with installation limit plates. Between the two groups of installation limit plates, a HEPA filter screen, an activated carbon fiber board, a particulate matter bearing plate, and a honeycomb activated carbon board are slidably arranged from top to bottom in sequence. The front edge position of the primary purification chamber is movably installed with a cover plate. This waste gas purification device can effectively combine with microorganisms in the waste gas to achieve sedimentation, achieving a further impurity removal effect. At the same time, the remaining circulating adsorption liquid drips into the bottom of the secondary purification chamber and is sprayed through a spray head by a circulating water pump in cooperation with a circulating water pipe, thereby achieving the effect of recycling, effectively saving energy, and being able to effectively disinfect and sterilize harmful substances in the waste gas, thereby meeting the emission standards and avoiding polluting the atmosphere, having a good environmental protection effect.

[0004] In the above application, since the waste gas reaches the primary purification chamber first and is adsorbed by filter plates such as activated carbon fiber plates, larger dust particles and the like will block the filter plates, resulting in a decrease in the passing rate of the filter plates and a reduction in work efficiency. Since the circulating adsorption liquid in the secondary purification chamber has no discharge port and filling port, the circulating adsorption liquid is recycled all the time, resulting in a decrease in the adsorption effect and failing to achieve a good adsorption effect.

[0031] Working principle: The waste gas first reaches the inside of the pretreatment purification chamber 1 through the waste gas passage 19. Start the induced draft fan 30. The pure water in the first circulating water pipe 5 is sprayed out from the first spray head 29 via the first mounting plate 20. The large particulate matter contained in the waste gas is mixed and settled to the inner bottom of the pretreatment purification chamber 1 by the pure water. A water pump is arranged at the inner bottom of the pretreatment purification chamber 1. The input end of the water pump is at the inner bottom of the pretreatment purification chamber 1, and the output end of the water pump is connected to the first circulating water pipe 5. The pure water is sprayed out by the first spray head 29 again via the first circulating water pipe 5. The waste gas after sedimentation reaches the lower part of the primary purification chamber 2 through the waste gas passage 19 at the bottom of the side wall of the pretreatment purification chamber 1. Due to the action of the induced draft fan 30, the waste gas flows, comes to the upper part of the primary purification chamber 2 from the lower part of the primary purification chamber 2 through the filtration of the filter element plate 8, and comes to the upper part of the secondary purification chamber 3 via the conduit 18. A second mounting plate 24 is arranged at the inner top of the secondary purification chamber 3. A second spray head 26 is fixedly connected to the lower part of the second mounting plate 24. The circulating adsorption liquid 22 sprayed out by the second spray head 26 will combine with the microorganisms in the waste gas to achieve the effect of further dust removal. The circulating adsorption liquid 22 drips into the bottom of the secondary purification chamber 3. A water pump is arranged at the bottom of the secondary purification chamber 3. The input end of the water pump is fixed at the bottom of the secondary purification chamber 3, and the output end of the water pump is connected to the second circulating water pipe 10. The circulating adsorption liquid 22 is sprayed out by the second spray head 26 again via the second circulating water pipe 10. The waste gas mixed with the circulating adsorption liquid 22 reaches the disinfection and sterilization chamber 4 through the further purification of the filler 23 through the waste gas passage 19. The disinfection and sterilization chamber 4 is divided into an oxidation chamber and a disinfection chamber by a partition plate 25. The oxygen brought by the active oxygen pump 14 reaches the oxidation chamber through the oxygen delivery pipe 13. Due to the strong oxidizing property of the active oxygen, it can effectively disinfect and sterilize the harmful substances in the waste gas. The waste gas after sterilization comes to the sterilization chamber and is finally disinfected by the ultraviolet lamp 28 on the side wall, and finally is discharged into the atmosphere through the exhaust pipe 15.
