Problems solved by technology

There is already a disinfection technology using ultraviolet lamps to disinfect ventilation ducts, but when the wind speed in the ventilation ducts is high, the air flows through the ultraviolet lamps quickly, and the radiation time received is too short, the radiation intensity is insufficient, and the ultraviolet dose is far from reaching disinfection Sterilization requirements; on the other hand, due to the characteristics of the ultraviolet lamp itself, the distribution of ultraviolet illuminance on the pipe section is uneven, resulting in dead angles with weak ultraviolet illuminance, which cannot effectively kill microorganisms flowing through the air
Therefore, the ultraviolet disinfection of ventilation ducts needs to solve the problems of uneven distribution of ultraviolet illumination and insufficient ultraviolet dose.

Abstract

The invention discloses an ultraviolet disinfection device and disinfection method for a ventilating duct, the ultraviolet disinfection device comprises a first fixing frame and a second fixing frame, the first fixing frame and the second fixing frame are connected through at least one ultraviolet lamp, one side or two sides of the ultraviolet lamp are provided with nanometer photocatalyst nets, and the nanometer photocatalyst nets are connected with the first fixing frame and the second fixing frame. The nanometer photocatalyst net is connected with the first fixing frame and the second fixing frame, and the nanometer photocatalyst net and the ultraviolet lamp are arranged in parallel. Correspondingly, the invention also provides a disinfection method using the ultraviolet disinfection device. The ultraviolet disinfection device for the ventilation pipeline provided by the invention is simple in structure, uniform in ultraviolet illumination distribution and sufficient in ultraviolet light dosage.

Description

technical field [0001] The invention relates to the technical field of disinfection devices, in particular to an ultraviolet disinfection device and a disinfection method for ventilation ducts. Background technique [0002] The purification and disinfection of the overall indoor air conditioning and ventilation system is the top priority of indoor air disinfection. There is already a disinfection technology using ultraviolet lamps to disinfect ventilation ducts, but when the wind speed in the ventilation ducts is high, the air flows through the ultraviolet lamps quickly, and the radiation time received is too short, the radiation intensity is insufficient, and the ultraviolet dose is far from reaching disinfection Sterilization requirements; on the other hand, due to the characteristics of the ultraviolet lamp itself, the distribution of ultraviolet illuminance on the pipe section is uneven, resulting in dead angles with weak ultraviolet illuminance, which cannot effectively...
