Embodiment Construction

[0034] The following is attached Figure 1-6 The present invention is further described.

[0035] like figure 1 As shown, the present invention includes a liquid storage tank 1, a pump 2, a base 3, a support 4, a photocatalytic reactor 5, a compound parabolic concentrator 6, a gas-liquid separator 7, a gas flow meter 8, a plane mirror 26 and parameters Measure components. The reaction liquid starts from the liquid storage tank 1 and enters the photocatalytic reactor 5 through the pump 2 . The hydrogen gas generated by the photocatalytic reaction is separated at the gas-liquid separator 7 and enters the gas flow meter 8 . The radiometer 9 is fixed on the bracket 4 to maintain the same inclination angle with the photocatalytic reactor 5; the temperature probe 10 is placed at the water inlet 16.

[0036] Through the coupling of the flat plate reactor and the light concentrating module, the solar energy can be directly used to photocatalytically decompose water to produce hydro...

Abstract

The invention discloses a concentrating fixed-film solar photocatalytic hydrogen production device. The device comprises a liquid storage tank, a base, a bracket, a photocatalytic reactor, a concentrating assembly, a gas-liquid separator and a parameter measuring assembly, wherein a bottom outlet of the liquid storage tank is connected with one end of the photocatalytic reactor through a pump, andthe other end of the photocatalytic reactor is sequentially connected with a gas-liquid separator and a gas flowmeter; the photocatalytic reactor is supported and fixed by the base and the bracket; the photocatalytic reactor comprises a reactor box body and a reactor cover plate having high light transmittance and located on the reactor box body, and the reactor box body is filled with a supported photocatalyst; and the concentrating assembly comprises a compound parabolic concentrator and a planar mirror added via a sunken design. With the concentrating assembly, the utilization rate of solar energy is increased, the distribution of light condensation rays on the photocatalytic reactor can be adjusted, and photocatalytic hydrogen production performance can be improved. By using the supported photocatalyst, extra energy input can be avoided, and operation cost is low; and the supported photocatalyst can be repeatedly used.

Description

technical field [0001] The invention belongs to the field of large-scale production of renewable energy, and relates to a photocatalytic water decomposition hydrogen production and hydrogen separation and measurement device under direct solar light, in particular to a concentrating fixed-film solar photocatalytic hydrogen production device. Background technique [0002] With the continuous consumption of conventional fossil energy such as coal, oil, and natural gas, serious energy supply crisis and environmental pollution problems have been caused, and the development of renewable energy is urgently needed. As an energy carrier, hydrogen has the characteristics of high energy density, convenient storage and transportation, the product of combustion is water, and it does not pollute the environment at all. Solar energy is the most abundant solar energy, clean and pollution-free, but its dispersion and instability make it difficult to use directly on a large scale. Solar phot...
