Problems solved by technology

[0003] The existing methods of hydrogen production mainly include the physical method of hydrogen production by electrolysis of water, the chemical method of hydrogen production by thermochemical method, and the biological hydrogen production method of biological fermentation hydrogen production. Among them, the first two methods consume a huge amount of energy for hydrogen production , but biological hydrogen production is quite special. In fact, using fermentation bacteria to treat some sugar-containing substances, such as food residues such as kitchen waste or some substances containing cellulose and fructose, the fermentation bacteria will decompose sugar and generate hydrogen, and can also be used in During the fermentation process, waste and other substances are decomposed to reduce environmental pollution and produce hydrogen. The specific operation is to mix fermentation bacteria and biomass into the fermentation tank, and the fermentation bacteria will only decompose the organisms. During anaerobic decomposition, the fermentation bacteria will produce Acetic acid is the main product represented, so the pH value in the fermentation tank decreases, which affects the growth environment of the fermentation bacteria itself. The present invention proposes a new biological hydrogen production device, which can adjust the environment in the fermentation tank in real time, such as pH value and Temperature, etc., provide the best fermentation environment for the fermentation bacteria, and increase the decomposition speed of the fermentation bacteria

Abstract

The invention belongs to the technical field of biological hydrogen production, and discloses a device for producing hydrogen through biomass gasification. The device comprises a fermentation tank, an acid-base detector arranged on the inner cavity wall of the fermentation tank, a liquid collecting barrel arranged below the fermentation tank, a heating barrel and a water suction pump which are arranged at the top of the fermentation tank, a heater arranged at the bottom of an inner cavity of the heating barrel, a thermometer arranged on the inner wall of the heater, and an exhaust pipe communicating with the inner cavity of the fermentation tank. A sodium carbonate solution in the heating barrel is heated to a constant temperature through the heater and conveyed into heat flow pipes through pipelines, the heat flow pipes are submerged in a mixed material in the fermentation tank, and the heat flow pipes are arranged in the fermentation tank and can uniformly heat the mixed material of mixed zymophyte and biomass in the fermentation tank. Therefore, the environment temperature of the mixed materials in the fermentation tank is increased and maintained, the purpose of temperature adjustment is achieved, the most suitable growth temperature range is provided for unfermented bacteria, and the fermentation rate is increased.

Description

technical field [0001] The invention belongs to the technical field of biological hydrogen production, and in particular relates to a device and method for biomass gasification hydrogen production. Background technique [0002] With the development of the times, people's awareness of environmental protection and the protection system have become more and more perfect, and people's pursuit of environmentally friendly and clean energy has become increasingly intense. Hydrogen energy is one of the main choices for environmental protection and clean energy, because its Not only is it rich in reserves on the earth, but its preparation technology has also made great progress. [0003] The existing methods of hydrogen production mainly include the physical method of hydrogen production by electrolysis of water, the chemical method of hydrogen production by thermochemical method, and the biological hydrogen production method of biological fermentation hydrogen production. Among them...
