An air purification device for eliminating volatile organic compounds and odorous substances

Abstract

The invention relates to an air purification device for eliminating a volatile organic matter and a peculiar smell substance. The device comprises a shell (1), the shell (1) is internally provided with two air ducts, namely a main air duct and an auxiliary air duct, wherein the main air duct comprises a main air inlet (9), a coarse filter screen (2), a coarse-effect filter assembly (3), a catalytic purification assembly (4), a main fan (5), an outlet filter screen (6) and a main air outlet (10) which are arranged sequentially; and the auxiliary air duct comprises an auxiliary air inlet (11), an ion generator (8) and an auxiliary air outlet (12) which are arranged sequentially, wherein the auxiliary air inlet (11) is located in the main air outlet (10), and the auxiliary air outlet (12) islocated between the coarse-effect filter assembly (3) and the catalytic purification assembly (4). Compared with the prior art, the air quality in a room, in a vehicle and in a cabin can be effectively improved by the air purification device for eliminating the volatile organic matter and the peculiar smell substance; and meanwhile, the catalytic purification assembly (4) can keep high activity ina relatively long time, does not need to be replaced frequently, and the air purification device for eliminating the volatile organic matter and the peculiar smell substance has the advantages of being small in size, high in efficiency and low in energy consumption.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to an air purification device for eliminating volatile organic compounds and peculiar smell substances for civil air purification and industrial waste gas treatment. Background technique [0002] In modern society, people pay more and more attention to the air quality of the environment they live in, especially in confined spaces with poor ventilation, such as closed rooms, cars and cabins. [0003] Various paints, coatings, adhesives, plastic parts and other factors will lead to the accumulation of a large amount of volatile odor substances such as formaldehyde, benzene, esters, etc. in the confined space, which will pose a serious threat to people's health. Remove harmful and foul odors in the confined space Gases are a growing concern. [0004] An air purifier, also known as an air cleaner, is a device that can absorb, decompose or transform various pollutants. Commonly ...

AI Technical Summary

Problems solved by technology

[0005] Filter-type and activated carbon-type purifiers are prone to saturation and need to be replaced frequently; photocatalyst-type purifiers have low efficiency in removing volatile organic compounds; ozone, plasma and electrostatic purifiers tend to generate too much ozone and must be used before entering a confined space. Inconvenient; Chinese patent discloses a "vehicle air purifier" with patent number 201510973761.X. This patent adopts a composite treatment method of ozone and electrostatic dust removal. perform air purification

The disadvantage of this device is that positive and negative ions are used for purification when the car is started, but the efficiency is low; after the engine is turned off, ozone is used for purification, but the ozone content is not easy to control, and it is easy to cause the aging of car interior materials. At the same time, when using this type of purifier During the process, it was found that formaldehyde, benzene, ketones, esters, hydrogen sulfide and other organic and inorganic pollutants or odorous substances will also undergo partial ionization and decomposition when passing through the ozone generator, and produce substances that are difficult to desorb naturally and adhere to the ozone generator. Cause the ozone generator to reduce or even damage the working efficiency
