Solar energy photocatalytic reactor based on condenser of composite paraboloid

Abstract

The invention publishes a solar energy photochemical catalysis reactor which bases on the compound parabolic condenser. At least a compound parabolic condenser is fixed through the bearing on the cant of the equipment. The glisten surfaces of the each compound parabolic condenser connect with the adjustment screw rod, a tubular reactor installs on the center of the compound parabolic condenser, and each tubular reactor connects together through the PVC tube. Through the coupling of the parabolic condenser and the tubular reactor to realize the solar optical fiber effective accumulation and use, the photocatalyst powder and the peroxide solution recycling move in the reactor internal, the catalyst accepts the light and catalysis when passes through the tubular reactor. The invention has simple operation,and may carry on each kind of photochemical catalysis reaction directly using the sunlight, the quantity of the compound parabolic condenser and tubular reactor may fluctuates by the design requirements, therefore the equipment may apply in each kind of different active photocatalyst.

Description

Technical field [0001] The invention belongs to the field of solar energy development and utilization, and relates to a photocatalytic reaction under direct solar light. In particular, it relates to a solar photocatalytic reactor based on a compound parabolic concentrator. Background technique [0002] As a kind of chemical reaction, photocatalytic reaction is currently widely used in energy and environmental protection field research. The principle of the photocatalytic reaction is that when the catalyst powder is irradiated by a light source of certain energy, the internal electrons are excited to transition from the valence band to the conduction band, thereby generating free electrons and holes in the conduction band and the valence band, respectively. When electrons and holes respectively migrate to the surface of the semiconductor, they will undergo a photocatalytic reaction with the adsorbed substances. For photocatalytic reactions, only the direct use of solar energy as a...

In addition, it is difficult to clean the catalytic bed after catalyst deactivation

And CN1631495A has reported a kind of fixed bed type solar energy air cleaning device, this invention does not adopt light concentrating device, so it can be expected that this reactor will not be very high to the utilization efficiency of sunlight
