Secondary filtering type air purification device

Abstract

The invention provides a secondary filtering type air purification device, and belongs to the field of environmental protection purification. A dustproof net cover is arranged on the outer side of a suction ventilator. A filter device is arranged in an inner cavity of a primary purification box. An ultraviolet sterilizer is arranged at the right end of the inner cavity of the primary purification box. Disinfection plates are arranged on the left side in a disinfection cavity. An ultraviolet sterilization lamp is fixedly arranged on the left side in a purification cavity. The lower end of an air outlet pipe is connected with an exhaust net through a telescopic air pipe. According to the device, a casing pipe is arranged on the right side of an inner cavity of the disinfection cavity, a sealing cover is arranged on the casing pipe, clear water and disinfection liquid can be added by opening the sealing cover, and the dual functions of washing dust removal and disinfection on gas are achieved; an activated carbon adsorption layer is arranged on the right side in the purification cavity, and the function of carrying out absorbent purification on the treated gas again is achieved; and the device has the beneficial effects of being simple in structure, high in practicality and good in purification and disinfection effect.

Description

technical field [0001] The invention relates to a facility related to environmental protection and purification, in particular to a secondary filter type air purification device. Background technique [0002] At present, the contradiction between air pollution caused by the development of industrialized society and people's continuous pursuit of high living standards is becoming increasingly prominent; indoor ventilation is relatively small, or public places such as shopping malls, stations, and supermarkets with a large flow of people, due to The air flow is small, and there are a lot of pollutants in the air, such as dust and smoke. Taking the smoke produced by cigarettes as an example, the toxic substances of second-hand smoke contained in the ambient air are no less harmful to passive smokers than active smokers. Light, especially the harm to young children is particularly serious; Although there are many types of air purifiers, the purification and disinfection are not ...

[0002] At present, the contradiction between air pollution caused by the development of industrialized society and people's continuous pursuit of high living standards is becoming increasingly prominent; indoor ventilation is relatively small, or public places such as shopping malls, stations, and supermarkets with a large flow of people, due to The air flow is small, and there are a lot of pollutants in the air, such as dust and smoke. Taking the smoke produced by cigarettes as an example, the toxic substances of second-hand smoke contained in the ambient air are no less harmful to passive smokers than active smokers. Light, especially the harm to young children is particularly serious; Although there are many types of air purifiers, the purification and disinfection are not ideal, and the filter material is inconvenient to disassemble and wash, and most air purifiers have disadvantages such as high cost and inconvenient movement; Therefore, improvements are needed
