And an air inlet and an air outlet are arranged on two sides of the reaction cabin.
The distance between the photocatalyst net and the ultraviolet lamp panel is 10-20 mm, and the wavelength of the ultraviolet lamp panel is 365-405 nm.
The reactor is characterized in that a supporting piece for installing a fan is arranged in the reaction cabin cavity, and the supporting piece and the photocatalyst net are arranged in parallel or are obliquely arranged in the reaction cabin cavity.
The air inlet and the air outlet are arranged on two sides of the reaction chamber cavity in a staggered mode.
The area of the air inlet is larger than that of the air outlet.
The air outlet is of a bell mouth-shaped structure.
Be provided with in the reaction chamber cavity and be used for settling support piece's slot, be used for settling the slot of ultraviolet lamp plate and be used for settling the slot of photocatalyst net, support piece, ultraviolet lamp plate and photocatalyst net are all pegged graft fixedly through respective slot.
And a cover plate is arranged on the reaction cabin cavity.
After adopting foretell structure, because the fan, ultraviolet lamp board and the photocatalyst net that design in proper order in the reaction chamber cavity, thereby can make the air get into the reaction chamber cavity, the photocatalyst in the reaction chamber cavity can produce the photocatalytic reaction of similar photosynthesis after absorbing the ultraviolet ray in sunlight or the irradiation light source, produce the free hydroxyl radical and the super oxyanion free radical that the oxidability is extremely strong, free harmful substance and microorganism in the air decompose into harmless carbon dioxide and water, reach the purpose that removes the peculiar smell, disinfect, restrain ethylene growth, especially rationally design the interval and the ultraviolet lamp wavelength of photocatalyst net and ultraviolet lamp, effectively give play to the photocatalyst maximum efficiency and saved the cost.
