Novel pump-free internal circulation type photosynthetic biological hydrogen production reactor

Abstract

The invention provides a novel pump-free internal circulation type photosynthetic biological hydrogen production reactor. The novel pump-free internal circulation type photosynthetic biological hydrogen production reactor comprises an outer reaction barrel, an inner reaction barrel and a gas collecting device, wherein a barrel cover is arranged at the top of the outer reaction barrel; the inner reaction barrel is arranged in the outer reaction barrel; an outer annular reaction chamber is formed between the inner reaction barrel and the outer reaction barrel; an inner circular reaction chamberis formed in the inner reaction barrel; the edge of the lower end of the inner reaction barrel is in contact with the bottom of the outer reaction barrel; a liquid permeating hole is formed in the lower part of the inner reaction barrel; a gas guide pipe is arranged at the top of the inner reaction barrel; an outlet of the gas guide pipe extends into the bottom of the outer annular reaction chamber; an exhaust port is formed in the barrel cover; and a gas inlet of the gas collecting device is connected with the exhaust port in the barrel cover. The novel pump-free internal circulation type photosynthetic biological hydrogen production reactor is simple and compact in structure and convenient to operate; the reactor is designed to be cylindrical, so that light is uniformly transmitted, andthe occupied area is small; and gas produced by the reactor is guided into reaction liquid again, so that stirring aerodynamic force is provided for the reaction liquid, energy consumption is effectively reduced, and low-energy-consumption and high-efficiency hydrogen production is realized.

Description

technical field [0001] The invention belongs to the technical field of rural energy in agricultural engineering, and in particular relates to a novel pumpless internal circulation photosynthetic biological hydrogen production reactor. Background technique [0002] Due to the rapid development of our country's economy, the demand for energy is constantly increasing, especially the demand for primary energy, which has brought serious energy problems and environmental problems. Therefore, finding a clean alternative energy source is an urgent task. However, in many emerging energy sources, the product of hydrogen combustion or catalytic oxidation is water or water vapor, which does not produce CO 2 and other greenhouse gases, not only alleviates the greenhouse effect, but also does not pollute the environment, and alleviates the problem of environmental pollution. At the same time, hydrogen has a high calorific value and can replace fossil fuels such as coal, oil, and natural ...
