Description

Technical Field

[0001] The utility model belongs to the technical field of spray tower circulating deodorization, and particularly relates to a river sewage deodorization circulating purification device. Background Technique

[0002] The purification treatment of river sewage generally refers to the treatment of rivers, which belongs to water conservancy projects. Generally, the silt in the river is transported through pipelines to a designated area for purification treatment, and the purified clear water is discharged. After the silt is filtered by a filter press, organic fertilizer can be made to turn waste into treasure.

[0003] During the process of river sewage treatment, in order to reduce the impact of odor on the working environment, a spray tower circulating deodorization device is generally used for deodorization treatment. As the use time increases, during the reverse convection process of the deodorization circulating liquid and the waste gas, the dust in the waste gas will accumulate in the deodorization circulating liquid, resulting in more dust in the deodorization circulating liquid, which is more likely to cause the blockage of the circulating nozzle. And as the use time prolongs, bacteria are likely to breed in the deodorization circulating liquid, thus generating odor. Therefore, it is necessary to design a river sewage deodorization circulating purification device to solve the above problems. Content of the Utility Model

[0021] In the following, embodiments of the river sewage deodorization and circulation purification device of the present utility model will be described with reference to the accompanying drawings.

[0022] Figure 1-2A river sewage deodorization and circulation purification device showing an embodiment of the present utility model includes a purification cylinder 1: a liquid inlet pipe 2 is installed at the upper end of the surface of the purification cylinder 1, a liquid outlet pipe 3 is installed at the lower end of the surface of the purification cylinder 1, the bottom of the purification cylinder 1 is fixedly connected by bolts to an impurity hopper 4, a valve 5 is installed at the bottom of the impurity hopper 4, a diamond filter screen 6 is welded to the bottom of the inner cavity of the purification cylinder 1, the inner cavity of the liquid inlet pipe 2 is communicated with the inner cavity of the diamond filter screen 6, the inner cavity of the liquid outlet pipe 3 is communicated with the inner cavity of the purification cylinder 1, a plurality of submerged ultraviolet germicidal lamps 7 are fixedly installed around the bottom of the inner cavity of the purification cylinder 1, and the submerged ultraviolet germicidal lamps 7 are arranged in a circular array on the outer surface of the diamond filter screen 6. By arranging the submerged ultraviolet germicidal lamps 7 outside the diamond filter screen 6, since the deodorization circulating liquid will increase its light transmittance after being filtered by the diamond filter screen 6, the sterilization efficiency of the submerged ultraviolet germicidal lamps 7 on the deodorization circulating liquid can be improved. The top of the purification cylinder 1 is fixedly connected by bolts to a top plate 8. A square rotating column 10 is rotatably connected to the inner cavity of the diamond filter screen 6, and the square rotating column 10 is rotatably connected to the bottom of the inner cavity of the purification cylinder 1. A plurality of fixing columns 14 are fixedly connected to the surface of the square rotating column 10, and a mounting plate 15 is fixedly connected to the surface of the fixing column 14. The distance between two adjacent upper and lower fixing columns 14 is the same, and the mounting plates 15 are alternately installed on the surface of the fixing column 14. By the alternate installation of the mounting plates 15, when the square rotating column 10 drives the scraper 16 to rotate to scrape the inner surface of the diamond filter screen 6, the scraper 16 will evenly scrape the inner surface of the diamond filter screen 6, thus avoiding the uneven scraping force of the scraper 16 on the diamond filter screen 6, which may cause the diamond filter screen 6 to tilt and affect the service life of the diamond filter screen 6. The scraper 16 is detachably installed on the surface of the mounting plate 15. By providing the scraper 16, the impurities attached to the surface of the diamond filter screen 6 can be scraped off, avoiding the blockage of the filter holes on the surface of the diamond filter screen 6 after long-term use, which affects the filtration efficiency. The scraper 16 is in contact with the inner surface of the diamond filter screen 6. A motor 9 is fixedly installed on the top of the top plate 8. The top of the square rotating column 10 extends to the outside of the top plate 8 and is detachably installed at the bottom of the output end of the motor 9.

A cover plate 13 is detachably installed on the top of the diamond filter screen 6.

[0023] Working principle: When the utility model is in use, the user introduces the deodorizing circulating liquid into the inner cavity of the diamond filter net 6 through the liquid inlet pipe 2 for filtration. The filtered deodorizing circulating liquid is discharged through the liquid outlet pipe 3. At the same time, the submerged ultraviolet germicidal lamp 7 is used to sterilize the filtered deodorizing circulating liquid to prevent bacteria from growing inside, improve the service life of the deodorizing circulating liquid, and drive the square rotating column 10 to rotate through the motor 9, thereby driving the scraper 16 to scrape the impurities attached to the inner surface of the diamond filter net 6. The scraped impurities will slowly precipitate and be collected in the inner cavity of the impurity hopper 4, and finally be discharged centrally through the valve 5. When it is necessary to replace the scraper 16, the top plate 8 is removed and the square rotating column 10 is pulled out of the inner cavity of the slot 12 in the mounting head 11. Then the top plate 8 is opened and the cover plate 13 is opened, and the square rotating column 10 is taken out of the inner cavity of the diamond filter net 6, so as to facilitate the user to replace the scraper 16.

[0024] In summary: For this river sewage deodorizing circulating purification device, the impurities in the deodorizing circulating liquid are removed through the diamond filter net 6, so as to prevent the impurities from blocking the circulating nozzles of the spray tower and affecting the deodorizing efficiency. With the use of the submerged ultraviolet germicidal lamp 7, the filtered deodorizing circulating liquid is sterilized, the growth of bacteria in the deodorizing circulating liquid is reduced, and the service life of the deodorizing circulating liquid is improved.
