The speed of efficient absorption layer is fast, and turbulence level is high, and air and the contact of photocatalysis Decomposition layer and efficient absorption layer are abundant, and air is clean
Net effect is good.As a kind of improvement of the utility model, photocatalysis Decomposition layer includes the porous fixation of about two parallel arrangements
Plate, the TiO 2 porous stratum granulosum between two porous fixed plates, several ultraviolet lamp beads are set to two porous fixed plates
Respectively close on the side of TiO 2 porous stratum granulosum, porous fixed plate located above is close to TiO 2 porous stratum granulosum
Side on be additionally provided with rotatable blade.By the way that ultraviolet lamp bead is respectively set in the both sides of TiO 2 porous stratum granulosum, by force
The discomposing effect of photocatalysis decomposition layer, and the blade being arranged rotates under the action of the air of flowing, accelerates the turbulent flow of air
Confusion degree, raising air come into full contact with photocatalysis Decomposition layer, strengthen clean effect.
It is high pressure nitrogen fill area, high pressure nitrogen as a kind of improvement of the utility model, between net air duct and Installation cabinet
The air pressure superatmospheric 5%~10% of fill area.Since the setting of high pressure nitrogen fill area makes between net air duct and Installation cabinet not
It is easily accessible dust, the clean cleaning in experiment cover, the quality for being conducive to pure air is kept to be guaranteed.
As a kind of improvement of the utility model, the both ends of air diffuser plate further respectively have deflector, the deflector
Parallel coaming plate arrangement.So that the pure air conveyed from the both ends of air diffuser plate is reclined coaming plate side flow, eliminates coaming plate
Both sides air flow blind angle that may be present, improve the clean level of operating space.
The beneficial effects of the utility model are as follows：
The vertical clean work station of the utility model, by the way that photocatalysis Decomposition layer is arranged by the organic gas in air point
Solution, while net air duct is set in Installation cabinet, and nitrogen higher-pressure region is formed between net air duct and Installation cabinet, dustless sky is provided
Gas circulation environment avoids the drug on operation console contaminated, protects operator to convey the air of high cleanliness to operating space
The health of member.
