Problems solved by technology

However, the experimental research results show that the equipment has disadvantages such as low oxidation efficiency and high indoor ozone content, which is easy to cause harm to the human body.
Another commonly used indoor air purifier is the filter method. Although it can effectively purify suspended solids and a small number of harmful substances in the indoor air, the chemical pollution caused by decoration cannot be eliminated. It needs to be replaced regularly and the use cycle is uncertain, and the indoor air pollutants adsorbed on the surface of the filter screen have not been completely removed, so the used filter screen needs post-processing

Embodiment Construction

[0012] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0013] Filled spherical nano-TiO 2 The composition of the gas purification combination device includes a housing 5, an air inlet 6 is opened on the side wall of the housing, an ultraviolet lamp 4 is arranged in the middle of the housing, and a clean air outlet 2 is opened at the bottom of the housing. Glass beads 7 coated with nano-scale titanium dioxide photocatalyst are filled between the lamp tubes. The shell is covered with a fiber fabric layer 3 . A fibrous activated carbon filter 8 is arranged between the bottom of the housing and the glass beads coated with nano-scale titanium dioxide photocatalyst.

[0014] Indoor air 1 containing organic pollutants is filtered by fiber fabrics under the action of an external conventional gas power source, and then enters the photocatalytic oxidation indoor air treatment device, where it contacts the glass beads coated w...

Abstract

The invention provides a combined device for gas cleaning with filled ball carrying nanometer titanium oxide. Sais device comprises shell, the side face of shell is equipped with air inlet, the middle part is provided with ultraviolet lamp, bottom is equipped with clean air outlet, and the place between shell and ultraviolet lamp is filled with glass bead coated with nanometer titanium oxide. The invention combines photocatalytic oxidation with absorption and filtering to clean room air, the device can be used in room air cleaner to increase clearance of pollutant in air. The device is mainly used for room air cleaning, especially clearing organic chemical matter caused by room finishing.

Description

(1) Technical field [0001] The invention relates to an air purification device, in particular to a device for treating pollutants in indoor air by combining photocatalytic oxidation technology with adsorption and filtration technology. (2) Background technology [0002] Indoor air purifiers are one of the main methods for purifying indoor air pollution in recent years. With the improvement of people's living standards, its application is more common. Domestically produced indoor air purifiers mostly use traditional purification methods such as filter negative ions, electrostatic dust collection, and ozone generation, which generally have disadvantages such as low processing efficiency and easy to cause secondary pollution. Although imported products adopt more advanced technology, they are expensive and most of them are relatively large in size. Take the ozone air purifier, which is widely used in households and has good user response, as an example. It releases ozone into...
