Photobiological hydrogen producing reactor with built-in light conducting scatterer

Abstract

The photobiological hydrogen producing reactor with built-in light conducting and scattering column consists of one reactor box with liquid inlet and liquid outlet; and one light accepting plate covering the top of the reactor box. It features that the light accepting plate has at least two light conducting and scattering columns fixed perpendicular to the light accepting plate and at least two parallel baffle plates perpendicular to the columns. The light accepting plate and the light conducting and scattering columns are made of organic glass or transparent resin. The present invention has the advantages of low cost, high hydrogen producing rate, etc, and may be used widely in environment protection, energy source and other industry.

Description

Photobiological hydrogen production reactor with built-in light guiding and scattering columns technical field The invention relates to a biological hydrogen production reactor, in particular to a photobiological hydrogen production reactor with a built-in light guiding and scattering column for realizing biological hydrogen production by using photosynthetic bacteria. Background technique Hydrogen production by photosynthetic bacteria is considered to be one of the most promising ways of biological hydrogen production (Debabrata Das, et al. Hydrogen production by biological processes: a survey of literature. International Journal of Hydrogen Energy 26 (2001) 13-28.). This is mainly because: photosynthetic bacteria hydrogen production has a high photochemical conversion rate in theory; it can avoid the problem of oxygen inhibition; the method has the ability to use a wide spectral range; the method has the ability to remove the capacity for organic pollutants. At present...

Problems solved by technology

The stirred tank photoreactor is based on the traditional microbial fermenter, adding light for the cultivation of photosynthetic bacteria and hydrogen production. Its advantage is that it has a large volume of culture solution in a limited area. The liquid can only reach the microorganisms, the light intensity attenuation is large, the photochemical conversion efficiency is low, and the shear force generated by stirring will inhibit cell growth and damage cells. In addition, the method of cell suspension culture can realize the continuous flow hydrogen production process, and at the same time, it is mixed with bacteria The loss of species (Michael Herrenbauer, Iris Perner, Karsten Schmidt, Design of a photo-bioreactor for modeling purposes, Chemical Engineering and Processing 38 (1999) 517-523;
