Problems solved by technology

The hydrogen production reactor has the following disadvantages: the reaction liquid flows in one direction in the reactor, and the contact process between photosynthetic bacteria and organic materials is short, resulting in insufficient reaction and low hydrogen production rate
However, it also needs to provide an external high-pressure air source device, which consumes more auxiliary energy

Abstract

The invention relates to a microbiology device, in particular to a photosynthetic hydrogen preparation device. The device consists of a cylindrical reaction cylinder (1), a guide flow cylinder (2) coaxially arranged in the reaction cylinder (1) and an electric-heating tube (4) arranged on the upper part of the reaction cylinder (1), wherein a light source is arranged in the cylinder wall of the guide flow cylinder (2); and the upper part of the reaction cylinder (1) is provided with a gas outlet (5) and a reactive fluid outlet (3). The device is characterized in that: a reactive fluid inlet tube (6) is arranged at the top of the reaction cylinder (1); the upper part of the guide flow cylinder (2) extends into the guide flow cylinder (2); and the elevation of the reactive fluid outlet (3) is higher than that of the upper end face of the guide flow cylinder (2). The photosynthetic hydrogen preparation device can push reactive fluid in the guide flow cylinder to flow downwards based on the pressure of a flow pump and the gravitational potential energy of the reactive fluid so as to accelerate the circulatory flow of the reactive fluid in a reactor. The device has good hydrogen preparation effect and obvious effect of helping to lower energy consumption.

Description

technical field [0001] The invention relates to a microbiology device, in particular to a biological hydrogen production device. Background technique [0002] Biological hydrogen production is a bioengineering technology that uses the physiological metabolism of microorganisms to decompose organic matter to produce hydrogen. It is of great significance to deal with organic waste and solve energy shortage problems. At present, the methods of biological hydrogen production mainly include photolysis of water to produce hydrogen, fermentation of hydrogen and photosynthesis of hydrogen. Hydrogen production by photolysis of water is a hydrogen production method in which microalgae and cyanobacteria use solar energy as energy and water as raw material to decompose water into hydrogen and oxygen through photosynthesis and its unique hydrogen production enzyme system; fermentation hydrogen production is heterogeneous Anaerobic bacteria use carbohydrates and other organic matter to p...
