Problems solved by technology

However, these air purifiers have some defects in performance: the materials for filtering solid suspended particles need to be replaced frequently; the adsorption materials have low purification efficiency for most inorganic pollutants, and the greenhouse gas CO in the air 2 The effect is little, and the regeneration of the adsorbent is also difficult; the negative ions produced are easy to combine with the dust in the air, adsorbed on furniture and walls, and when people walk around, they float into the air again to form "heavy ions" and produce secondary secondary pollution

Description

1. Technical field [0001] The invention relates to a limited space air purification device for civil and industrial use. 2. Background technology [0002] With the development of modern industry, the air quality that human beings rely on for survival is declining day by day. The main reason for the decline in air quality is the large amount of harmful gases emitted by human production and life, such as COx, NOx, SOx, H 2 S, HF, HCl, Cl 2 And a small amount of organic matter, etc., as well as various dusts produced by human activities, as well as the pollution of the ambient air by solid suspended particles such as sand and dust caused by climate deterioration. In addition, people's long-term activities in relatively closed spaces (such as hotels , hotels, conference rooms, waiting rooms, etc.) have also led to a decline in air quality in limited spaces. With the improvement of people's living standards, the requirements for air quality are also getting higher and higher. ...
