Abstract

The invention relates to a dark-fermentation photosynthetic united hydrogen production device and a dark-fermentation photosynthetic united hydrogen production method. The device comprises a support, wherein a photosynthetic biological hydrogen production reactor is placed on the support; a dark-fermentation biological hydrogen production reactor is arranged inside the photosynthetic biological hydrogen production reactor, and the top of the dark-fermentation biological hydrogen production reactor is higher than that of the photosynthetic biological hydrogen production reactor; a light insulation heat preservation layer is arranged between the photosynthetic biological hydrogen production reactor and the dark-fermentation biological hydrogen production reactor. According to the device, the lighted area of the photosynthetic hydrogen production reactor is increased, and the space is saved; a dark-fermentation biological hydrogen production reaction and a photosynthetic biological hydrogen production reaction can be performed at the same time, and the reaction time is shortened; by virtue of the light insulation heat preservation layer, the heat loss of the dark-fermentation reaction is reduced, and the energy consumption is reduced, and the hydrogen production efficiency is improved. In addition, the occupation area of the device is small; the hydrogen production method is easy to operate; modernization is easily realized, and the device can be widely applied to the environmental protection industry, the energy industry, the food industry, the feed industry and other industries, and has a great application prospect.

Description

technical field [0001] The invention relates to the technical field of agricultural engineering energy utilization, in particular to a dark fermentation photosynthesis combined hydrogen production device and a hydrogen production method thereof. Background technique [0002] Energy shortage and environmental pollution caused by energy production and consumption have become the two most serious problems faced by human beings in the 21st century, and the development of new energy is imminent. Among all alternative energy sources, hydrogen is recognized by the energy industry as the most ideal alternative energy source for fossil fuels due to its clean combustion, high energy density, and renewability. Traditional hydrogen production technologies mainly include hydrogen production by electrolysis of water and hydrogen production by fossil fuels, that is, hydrogen production by chemical method, which needs to consume a large amount of non-renewable resources such as electric ene...
