Tray bubble type biomass continuous hydrogen production method and device

Abstract

The invention relates to a tray bubble type biomass continuous photosynthetic hydrogen production method and device, belonging to the technical field of biomass photosynthetic hydrogen production. The method is characterized in that by utilizing sunlight, under the conditions of a built-in light source and a closed volume, biomass alternately passes through quartz side optical fiber trays and U-shaped heat exchanger trays, and under the bubble effect of reflux hydrogen, a continuous hydrogen producing process is realized by suspension heat exchange and dark-and-light fermentation. The method provided by the invention is simple in process and convenient to operate. The device is mainly composed of a sunlight transmitter, a tray type fermentation reaction tank, a heater, a gas chamber, a bubble chamber, a reaction liquid reflux part and a hydrogen reflux part. The device provided by the invention is reasonable in design and simple to operate, can ensure that the temperature of the reactor is uniform, realizes alternate dark-and-light fermentation of feed liquid, and achieves biomass continuous hydrogen production under an environmental condition of lower temperature, thereby reducing the limits of conventional energy resource consumption and hydrogen production by low-temperature fermentation, improving the biomass hydrogen producing efficiency, and realizing stable, efficient and continuous operation of the reactor.

Description

technical field [0001] The invention belongs to the technical field of biomass photosynthetic hydrogen production, and in particular relates to a method and device for continuous photosynthetic hydrogen production of tray bubble biomass. Background technique [0002] Facing the current situation that conventional energy is very scarce and environmental pollution is becoming more and more serious, hydrogen is recognized by the energy industry as a The most ideal alternative energy source for fossil fuels, many scientists and economists believe that the future era is the era of hydrogen energy and hydrogen energy economy. In the process of hydrogen development, because the world has very rich biomass resources, it is the only renewable energy that can be stored and transported, and the use of biomass to produce hydrogen has become a hot technology that is competing for development in the world today. Biomass hydrogen production mainly includes biomass gasification hydrogen pr...

Problems solved by technology

[0003]In my country, biomass photosynthetic hydrogen production started relatively late, and hydrogen production methods and devices are not mature enough, and are still in the experimental stage

In the process of biomass photosynthetic hydrogen production, most of the artificial light sources are used as the light supply method, and the operating cost is relatively high, which affects the competitiveness of hydrogen and fossil energy; the external light source setting method is limited by the transparent material of the reactor. It is difficult to keep the reactor warm, and the light utilization rate of the external light supply is low, and the reaction solution is unevenly illuminated, so that the hydrogen production effect of the reactor is poor, and the hydrogen production requirements cannot be met in a low temperature environment; when using a built-in light source, due to the structural design of the reactor It is unreasonable and cannot solve the problems of light and dark fermentation, uniform feed liquid temperature, and continuous hydrogen production, which restricts the large-scale application of hydrogen production from biomass
