Reach catharsis.The working principle of air purifier is mainly filtered by nethike embrane, and such as volatility of the pollutant in air
Organic matter (VOCs) can not be removed.This is also the big difficulty for solving problem of environmental pollution.
Photocatalysis oxidation technique is a kind of novel method for removing VOCs and the other organic compounds of removal.It is to utilize
The strong oxidizing property hydroxyl radical free radical and negative oxygen ion that semiconductor light-catalyst generates under the irradiation of ultraviolet light, due to hydroxyl free
The presence of base leads to the radical reaction that is mutually related of a series of complex, and these reactions eventually lead to the mineralising drop of organic matter
Solution, is oxidized organic matter and is reduced to harmless inorganic matter.To remove the various pollutants in air or in water, reach purification
Purpose.And catalyst itself is not lost by any decrement, it will not poison deactivation or replacement due to load problem.But
It is that there is presently no widely promote and apply for photocatalysis oxidation technique.The main reason is that: (one) selects a kind of not only effective but also resistance to
Carrier of photocatalyst does not have a new breakthrough, i.e., it is rotten how solid, powdery photochemical catalyst to be fixed on a kind of ultraviolet resistance for a long time
On the object of erosion；(2) ultraviolet source and catalyst in a limited space in optimal placement design problem, i.e. photochemical catalyst energy
It is maximumlly irradiated by light source, the oxidation reaction area of photochemical catalyst Yu medium processed, Lai Tigao treatment effeciency is increased with this；
(3) in a limited space in photochemical catalyst and medium processed effective haptoreaction process rational design problem.
