Continuous-flow and ultrasonic-wave light biological hydrogen producing reactor

Abstract

The invention discloses a continuous-flow and ultrasonic-wave light biological hydrogen producing reactor comprising a light source, a transparent tank irradiated by the light source and an ultrasonic cell crusher, wherein one side of the transparent tank is provided with a liquid inlet, the other side is provided with a liquid outlet, and the top of the transparent tank is provided with an air inlet and an air outlet; an amplitude transformer of the ultrasonic cell crusher vertically and downwards extends into a bacterium suspension filled in the transparent tank, and air sealing is arranged between the amplitude transformer and an upper cover of the transparent tank. The continuous-flow and ultrasonic-wave light biological hydrogen producing reactor combines a flat plate type reactor and the ultrasonic cell crusher so as to enhance organic matter as a carbon source in a degraded solution and raise the hydrogen producing speed of photosynthetic bacteria; when low-strength ultrasonic waves propagate in a medium, the continuous-flow and ultrasonic-wave light biological hydrogen producing reactor can change the permeability of a cell membrane, reinforce matter delivery, increase the metabolic activities of bacteria and promote the generation of useful matter; the continuous-flow and ultrasonic-wave light biological hydrogen producing reactor enhances the speed of a reactant entering the active position of enzyme or cells, promotes the mass transfer diffusion process that a product departs from the active center of the enzyme and enters a liquid medium, raises the enzyme activity, promotes the catalytic reaction of the enzyme and raises the speed of biological reaction.

Description

technical field [0001] The invention relates to a photobiological hydrogen production reactor, in particular to a continuous flow ultrasonic photobiological hydrogen production reactor. Background technique [0002] Hydrogen production by photosynthetic bacteria is considered to be one of the most promising ways of biological hydrogen production (DebabrataDas, 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. [0003] In the prior art, there are three types of photobiological hydrogen production reactors: tube type, flat plate type, and stirred tank type. The flat-plate photobioreactor has a stron...

Problems solved by technology

However, in the above three types, the cell membrane in the bacterial suspension is thicker, the hydrogen produced in the cell membrane is not easy to pass through the cell membrane, and the substrate in the bacterial suspension is difficult to enter the cell membrane. Therefore, there has always been a problem of low hydrogen production rate.
