Abstract

This invention discloses an equipment to prepare hydrogen by photosynthetic biologic reaction, which is composed of solar collector, optical fiber, photonic biologic reactor, cleaning device, hydrogen storage device and heater with constant temperature. The head of the optical fiber is connected with the solar collector and the end is connected with photonic biologic reactor which is in turn connected with cleaning device and hydrogen storage device through pipeline. There is a heater with constant temperature outside the photonic biologic reactor. This equipment of hydrogen preparation transfers the focused and filtered solar to all parts in the reactor by optical fiber, which improves the poor illumination density issue at deep area and make solar distributed uniformly in the reacting liquid so that to reach high efficiency of solar transfer.

Description

technical field [0001] The invention relates to a photosynthetic biological hydrogen production device, in particular to a solar photosynthetic biological hydrogen production device. Background technique [0002] With the continuous progress of society and the continuous improvement of the degree of industrialization, the demand for energy by human beings is increasing day by day, and traditional fossil energy can no longer meet the needs of social development. The use of traditional energy also discharges a large amount of waste gas and dust into the atmosphere. , the environmental pollution, greenhouse effect and acid rain caused by the carbon dioxide, sulfur dioxide and nitrogen oxides generated by it make the energy of the 21st century face a huge challenge. As a promising clean energy in the future, hydrogen is considered to be the best alternative energy for fossil fuels due to its high energy and clean combustion. Focusing on the future energy structure, the research,...
