High-frequency pulse light air purification and disinfection device

Abstract

The invention discloses a high-frequency pulse light air purification and disinfection device. A large amount of air flow is sucked into an air inlet door under the action of a cross flow blower, dust and fibers are filtered through a primary filter screen, and the air flow enters a high-frequency pulse light assembly. By the irradiation of high-frequency pulse light, at the same time of killing bacteria and viruses in the air, a nano titanium dioxide indoor nano photocatalyst is excited to perform full photocatalytic oxidation reaction, and organic volatile gases such as formaldehyde, benzene, ammonia and the like in the air are cleared; residual harmful gases and the like are adsorbed through an active carbon fiber chamber; and the clean air becomes fresh air because negative ions are increased, and the fresh air is blown out from an air outlet through an air guide fence at the top of the high-frequency pulse light assembly. By integrating three technologies comprising a C band 253.7nm ultraviolet technology, a high-frequency oscillation technology and a nano photocatalyst technology into a high-frequency pulse light air purification and disinfection technology, the problems of 'high efficiency and high running cost' of the conventional air purification and disinfection device are well solved, and ideal air purification and disinfection effects are acquired.

Description

Technical field [0001] The invention relates to a device for purifying and disinfecting air, which is harmless to human body, saves energy, does not require consumables, and has no secondary pollution and side effects. Background technique [0002] Existing air purification technologies include chemical methods, negative ions, ozone, adsorption methods, plasma, ultraviolet rays, photocatalysis, etc. Chemical methods are gradually eliminated due to secondary pollution and side effects; negative ion methods generate negative oxygen ions, and at the same time produce trace amounts of ozone, which can improve air quality; although ozone has a significant disinfection effect, it is harmful to humans and needs to be controlled; adsorption methods include activated carbon Filtration, multi-layer filtration, molecular sieve, high-voltage electrostatic adsorption, etc., have the problem of processing and cost of adsorption materials; plasma and ultraviolet rays can effectively kill m...
