specific Embodiment approach 1

[0009] Specific implementation mode one: combine figure 1 To illustrate this embodiment, the photofermentation anaerobic fluidized bed hydrogen production reactor of this embodiment includes a water inlet tank 1, a water inlet pump 2, a reactor body 3, a gas flow meter 7, a water inlet pipe 10, a gas outflow pipe 12 and two A group of lighting systems 6, a group of lighting systems 6 are respectively arranged on the left and right sides of the reactor body 3, the bottom of the reactor body 3 communicates with the water inlet tank 1 through the water inlet pipe 10, and the water inlet pump 2 is installed on the water inlet pipe 10, and the reaction A gas outflow pipe 12 is installed on the upper cover of the device main body 3, and the gas flow meter 7 is installed on the gas outflow pipe 12;

[0010] The photofermentation anaerobic fluidized bed hydrogen production reactor also includes an activated carbon fiber adsorption carrier 4, a return pump 5, a single pipe 8 in the sed...

specific Embodiment approach 2

[0011] Specific implementation mode two: combination figure 1 Describe this embodiment, the carbon fiber specific surface area of ​​the activated carbon fiber adsorption carrier 4 of this embodiment is 1500m 2 / g, the micropore radius is Total pore volume 705±15×10 -3 ml / g, the length of chopped strands is 0.1mm. In this way, the photofermentation bacteria are adsorbed on the outer surface of the carbon fiber, so that the photofermentation bacteria can receive light more effectively. When the light propagates to the surface of the activated carbon fiber, the light energy is fully absorbed and utilized by the photofermentation bacteria adsorbed on the outer surface of the carrier. , therefore, the utilization rate of light energy is improved more effectively. Other compositions and connections are the same as in the first embodiment.

specific Embodiment approach 3

[0012] Specific implementation mode three: combination figure 1 The present embodiment will be described. The reflux pump 5 of the present embodiment adopts a reflux pump with a flow rate of 150 ml / min. With such a setting, the carrier is in a suspended fluidized state, with good mass transfer conditions, and the microorganisms are easy to fully contact with the wastewater, and each photofermentation bacteria adsorbed on the surface of the carrier can receive light and produce hydrogen, effectively improving the Light energy utilization efficiency of photofermentation hydrogen production reactor. Other compositions and connections are the same as those in Embodiment 1 or Embodiment 2.

[0013] Specific implementation mode four: combination figure 1 To illustrate this embodiment, the lighting system 6 of this embodiment adopts an incandescent lighting system, and the average light intensity is controlled to be 4000 lx. Such setting can effectively provide sufficient light en...

Abstract

The invention discloses a photo-fermentation anaerobic fluidized bed hydrogen production reactor and relates to an anaerobic fluidized bed hydrogen production reactor. The invention aims to solve the problems of susceptibility to losing biomass and low utilization of light energy of the conventional photo-fermentation hydrogen production reactor. In the reactor, one end of a return tube is inserted into the main body of the reactor from the upper cover of the main body of the reactor, and the other end of the return tube is communicated with a water inlet tube; the connecting point of the return tube and the water inlet tube is between a water inlet pump and the main body of the reactor; a return pump is mounted on the return tube; an active carbon fiber absorbing carrier is filled in themain body of the reactor; one end of a settling area single tube is mounted on the middle side wall of the main body of the reactor, and the other end of the setting area single tube is communicated with a supernate outlet tube; the setting area single tube is arranged in an inclined manner; the connected end of the settling area single tube and the main body of the reactor are pressed against the connected end of the setting area single tube and the supernate outlet tube; and an outlet pump is mounted on the supernate outlet tube. The reactor is used in photo-fermentation anaerobic fluidizedbed hydrogen production.

Description

technical field [0001] The invention relates to an anaerobic fluidized bed hydrogen production reactor, in particular to a photofermentation anaerobic fluidized bed hydrogen production reactor, which belongs to the technical field of fermentation hydrogen production. Background technique [0002] Energy is an important basic resource for the development of human society. With the development of the world economy, the rapid increase of the world population and the continuous improvement of people's living standards, the world's energy demand continues to increase, which leads to increasingly fierce competition for energy resources, aggravated environmental pollution and increased pressure on environmental protection, forcing the world to Governments and scientists of various countries are committed to finding alternative fossil energy sources, that is, new renewable clean energy sources that do not pollute the environment or have low pollution. As a low-cost, low-energy gree...
