Biological hydrogen production device

Abstract

The invention discloses a biological hydrogen production device. The biological hydrogen production device comprises a crushing machine, a fermentation tank and an air washing device, wherein the crushing machine comprises a machine case provided with an inner cavity, a crushing device is arranged in the inner cavity, the inner cavity is divided into a crushing cavity and a blending cavity by virtue of a separating board, a plurality of communicating holes communicating the crushing cavity with the blending cavity are formed in the separating board, the crushing device is arranged in the crushing cavity, a crushing substrate inlet and a blending substrate inlet are respectively formed in the upper ends of the crushing cavity and the blending cavity, a mixed substrate outlet provided with a valve is formed in the lower end of the crushing cavity, the fermentation tank is connected with the crushing machine, the air washing device is connected with the fermentation tank, and the air washing device comprises at least one air washing tank, wherein at least one air washing tanks are sequentially connected. The biological hydrogen production device has the advantages that the blending cavity is arranged in the crushing machine, the crushing substrate and the blending substrate can be fully mixed while the crushing substrate and the blending substrate are crushed, the practice that crushing is firstly carried out and then stirring is carried out in the conventional technology is replaced, hydrogen production time is greatly shortened, the crushing substrate and the blending substrate are mixed more fully and more thoroughly, and a fermentation effect is better.

Description

technical field [0001] The invention relates to the technical field of biological fermentation hydrogen production, in particular to a biological hydrogen production device. Background technique [0002] Energy is an important basic resource for the development of human society. The rapid development of economy, the rapid growth of population and the continuous improvement of living standards have led to a rapid increase in energy demand. As an ideal alternative energy source, hydrogen energy has broad application prospects and huge market potential in the fields of clean energy production, resource regeneration, and environmental protection. [0003] Fermentative biological hydrogen production technology is an emerging high-tech in the field of energy and environmental protection. It uses waste biomass as raw material to produce clean renewable energy hydrogen through microbial fermentation, integrating renewable energy production, waste treatment, carbon dioxide emission ...

AI Technical Summary

Problems solved by technology

[0004] At present, in terms of biohydrogen production equipment, there are few complete sets of biohydrogen production equipment specifically for waste such as domestic garbage, residual activated sludge, agricultural and forestry waste, or high-concentration organic wastewater. It can be used to treat waste, but it often has the problem of low hydrogen production efficiency. When producing hydrogen, first use a pulverizer to pulverize the substrates such as domestic garbage organic matter, remaining activated sludge, agricultural and forestry waste, or high-concentration organic wastewater, and then Add the pulverized substrate into the fermenter, and at the same time add the necessary reconciliation substrates such as carbon source, nitrogen source, growth factor, which are usually viscous or liquid, and then use the fermenter The set agitator stirs and mixes these blended substrates and pulverized substrates to help fermentation, but the device has the following defects: the hydrogen production time is long, the mixing effect of the blended substrates and pulverized substrates is poor, the fermentation effect is poor, and even There will be a situation where the stirring device does not stir
