Description

Technical Field

[0001] The utility model relates to the technical field of water treatment devices, in particular to a medium-pressure ultraviolet disinfection water treatment device. Background Art

[0002] Medium-pressure ultraviolet disinfection technology is an efficient, environmentally friendly and reliable disinfection method. Generally, the wavelength of medium-pressure ultraviolet light is between 250-280 nanometers. This wavelength is called the "sterilization wavelength" and can destroy the nucleic acids of bacteria and viruses, making them lose their ability to reproduce, thereby achieving the disinfection effect. In water treatment equipment, medium-pressure ultraviolet light can quickly kill bacteria and viruses and complete the disinfection process in a short time.

[0003] For example, patent number CN221051631U discloses a medium-pressure ultraviolet disinfection water treatment device, which relates to the field of medium-pressure ultraviolet disinfection technology, including a disinfection box, the outer surface of which is fixedly connected to a water outlet pipe, and a cleaning mechanism is provided inside the disinfection box, the cleaning mechanism includes a water wheel and two movable racks, and the outer surfaces of the two movable racks are fixedly connected to five racks. Through the setting of the cleaning mechanism, when water flows through the outlet pipe, the water flow will drive the water wheel to rotate, and the rotation of the water wheel drives the chute plate to move back and forth through the crank, so that the movable rack drives multiple racks to move back and forth, and the movement of the rack will drive the rotating tube to rotate through the gear, and the rotation of the rotating tube will drive the scratching blade to rotate and scratch the impurities attached to the surface of the ultraviolet disinfection lamp tube, thereby keeping the surface of the ultraviolet disinfection lamp tube clean, and effectively avoiding the problem that impurities in the flowing water will block the ultraviolet rays from diffusing to the outside, resulting in a weakened disinfection effect;

[0004] Generally, the effect of ultraviolet disinfection treatment is affected by UV intensity and residence time. However, the water flow of the medium-pressure ultraviolet disinfection water treatment device in the patent enters through the water inlet pipe and is discharged from the water outlet pipe. The two are at the same level. When the water flow is faster, the water flow stays in the disinfection box for a shorter time, affecting the overall disinfection treatment effect.
