Sterilization processing device dedicated for blast pipe

Abstract

The invention discloses a special sterilization treatment device of air duct suitable for multiple air ducts, comprising ultraviolet pipe sterilizer and installing support fixed with air duct. The installing support is set in the air duct on the flow direction of air duct. Said ultraviolet pipe sterilizers are set at two ends of said installing support by the installing structure of sterilizer. The length direction of ultraviolet pipe adopted by the invention is the same with the flow direction in the air duct and is set at the center position of air duct. The length direction is near the main flow direction. The available time when air flow passes through the special sterilization treatment device of air duct is long and bacterial virus can be killed in effect. And composite ultraviolet lamp pipe is used to carry out oxidation for formaldehyde, ammonia and benzene so on in room to realize the treatment for volatile organic compound in room.

Description

technical field [0001] The invention relates to a sterilization treatment device, in particular to a special sterilization treatment device for air ducts in an air-conditioning system. Background technique [0002] With the improvement of people's quality of life and more attention to their own health, the issue of indoor air quality (IAQ) has become the focus of attention. At present, most commercial buildings and high-end residences are equipped with central air-conditioning systems. While this centralized air-conditioning system brings convenience to people, it also has many disadvantages. [0003] Because most of the existing central air conditioners and traditional air purifiers only use filter devices to filter "inhalable particulate matter", they are powerless to major pollutants such as microorganisms and odors. The core of indoor air quality is germs and viruses and harmful volatile organic compounds (VOCs) such as ammonia, formaldehyde, and benzene. Facts have pro...

AI Technical Summary

Problems solved by technology

However, there are some problems in the existing equipment. As shown in Figure 1, the lamp tube is installed on the top and bottom of the air duct, and the direction of the lamp tube is perpendicular to the direction of the airflow. Therefore, the irradiation time of the UVC ultraviolet rays on the airflow is too short to achieve the effect of killing bacteria. Cumulative radiation intensity of the virus

[0005] As shown in Figure 2, for large-sized air ducts, the existing equipment is installed on the side wall of the air duct, which is too far away from the main air flow in the air duct, and the sterilization effect is poor

In addition, the existing equipment is installed perpendicular to the direction of the airflow, so the parts facing the direction of the airflow, facing away from the direction of the airflow, and the parts where the airflow is close to the reflector are prone to dust accumulation, which will seriously affect the penetration of ultraviolet rays, which is not conducive to the sterilization effect
