Abstract

The invention relates to a rotary-type photocatalysed or adsorptive reactor, comprising a sink, a rotating wheel, a water inlet and a water outlet and a light source. The reactor is characterized in that the sink is oblique; the rotating wheel is mounted on the sink horizontally, connected with two sides of the sink via a central axis and provided with a neck; a sheet is mounted on the neck, and both sides of the neck are loaded with catalyst, film or absorbing agent; parts of the rotating wheel breaks the surface of the water, and the sheet on the rotating wheel is shocked by stream to promote the rotating wheel to slowly rotate; sunlight or ultraviolet lamp can be taken as light source; or the rotating wheel can be connected with bearings on both sides of the sink via the central axis and connected with a reducing motor. The reactor can greatly increase the contact area among catalyst light sources and pollutants, enlarging photopermeability by using glass sheets, and prolonging reaction time. The reactor features simple and compact structure, little energy consumption, high clearance, low processing cost, moderate processing condition, and easy realization of industrialization.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to equipment used for degrading organic matter in urban micro-polluted water, or sewage produced in chemical industry, petroleum, petrochemical industry or medicine, in particular to a wheel-type photocatalytic or adsorption reactor. Background technique [0002] In terms of photocatalytic reactors studied at home and abroad, they can be divided into suspension type and supported type according to the form of catalyst in the reactor. The suspension type can improve the photocatalytic efficiency, but the recovery of the catalyst is difficult and the recovery cost is high. The supported type can solve the problem of catalyst recovery very well, but the specific area of ​​the reaction is greatly reduced, which reduces the photocatalytic efficiency. If the problem of the contact area of ​​the reaction in the reactor can be solved, the supported photocatalytic reactor will be a go...
