Embodiment Construction

[0022] As shown in Figure 1, B, C, E, and F are the vertices of the cross-section of the compound parabolic condenser 3 without truncation and truncation, respectively, and M, N, G, and H are the half acceptance angles θ, respectively. c And truncation angle θ d The intersection of the incident outermost light ray and the compound parabolic concentrator 3. The tubular reactor 4 should be placed as close as possible to the apex P of the involute in the CPC to achieve the maximum reception of the reflected light in the CPC by the tubular reactor 4. According to the actual reaction needs and comprehensive consideration of the cost, the CPC can be truncated. As shown in the dotted line EF in Figure 1, the concentration ratio of CPC will decrease at this time, but the cost will also decrease.

[0023] As shown in Figure 2, each figure shows the convergence of incident light rays from different angles on the surface of the reaction tube in the compound parabolic condenser 3. Under the c...

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...
