Abstract
The invention discloses a dual-waveband ultraviolet lamp tube and a disinfection method thereof. The dual-waveband ultraviolet lamp tube comprises a dual-waveband quartz lamp tube and two lamp holders at the left end and the right end. The dual-waveband quartz lamp tube and the two lamp holders at the left end and the right end are in sealing connection. The dual-waveband lamp tube is composed of a short-waveband ultraviolet band segment and a medium-waveband ultraviolet band segment, and the light of two wavelengths is released segmentally. A short-waveband quartz tube and a medium-waveband quartz tube of the dual-waveband lamp tube are formed through sintering integrally. According to the invention, the dual-waveband ultraviolet lamp tube and the disinfection method thereof are capable of simultaneously producing ultraviolet rays of two wavebands, i.e., 184.9 nm and 253.7 nm and segmentally releasing the ultraviolet rays of the two wavebands, so that after ozone is generated, a strong oxidizing agent, i.e., hydroxyl free radical, can be generated subsequently. Under the joint effects of the ultraviolet rays of the two wavebands of 184.9 nm and 253.7 nm, the hydroxyl free radical can kill bacteria, viruses and microorganisms, realize light wave bond breaking, and degrade such poisonous and harmful gases in the air as organic and inorganic pollutants, thereby effectively removing various poisonous and harmful substances in the environment.
