Description

A kind of air cleaning unit with photocatalyst structure
Technical field
The present invention relates to air purification field, and in particular to a kind of air cleaning unit with photocatalyst structure.
Background technology
Air purifier is also known as " air cleaner ", air cleaner, clarifier, is to refer to adsorb, decompose or convert Various air pollutants (generally comprise finishing pollution, bacterium, the anaphylactogen of PM2.5, dust, pollen, peculiar smell, formaldehyde etc Deng), the product of air cleanliness is effectively improved, family expenses, commercialization, industry, building are broadly divided into.The filter screen technology of air purifier Be primarily referred to as taking HEPA (High efficiency particulate air Filter, high efficiency particle air filter) filter screens or The pollutant that active carbon filter screen came in air filtering, but two kinds of filter screens have respective advantage and disadvantage, and the advantage of HEPA filter screens is Effective and safe, is the main technology for removing particulate pollutant in air, but have the disadvantage that suspended particulates can only be filtered out, can not filter out Pernicious gas.There is good gas-tight design using the air purifier of HEPA filter screens, otherwise air can lose around screen pack Filter effect.And activated carbon is a kind of loose porous material, its flourishing gap structure makes it have very big surface area, so Volatile organic macromolecule material, such as stupid, toluene are easily absorbing, and is also loaded cold catalyst technology, is had for formaldehyde etc. The catalytic decomposition of poisonous gas.
The species of air purifier is various on the market at present, but the effect of purification is but difficult to the expectation for reaching people, main If formaldehyde, toluene that the limitednumber of the filtrable pollutants in air of these clarifiers, particularly interior decoration are produced etc. Toxic and harmful gas, with poor sealing, it is impossible to which the effective defect for filtering out toxic and harmful gas, filter effect does not reach The expectation of people;In addition, its function of existing air purifier is more single, such as, in hot summer, it can not provide system Cold effect, and occupy certain space, caused to one family than larger loss, so being badly in need of a kind of coverage rate more Extensively, the more preferable air purifier of clean-up effect.
The content of the invention
The invention aims to solve above-mentioned technical problem, there is provided a kind of air cleaning dress with photocatalyst structure Put, the apparatus structure is simple, reasonable in design, purification efficiency is high, its internal air purification structure integrated level height and installing/dismounting Convenient, the later stage is changed and Maintenance and Repair are convenient.
