High-efficiency microorganism hydrogen preparation and hydrogen energy-electric energy conversion integrating apparatus

Abstract

The invention refers to a device for producing hydrogen by using microbe to yeast organic substances and conversion of hydrogen energy and electricity energy. It sets biological hydrogen producing reaction device, gas purifying device inlet connects with the outlet of reaction device, the hydrogen device is connected with purifying device, hydrogen energy and electricity energy device inlet is connected with the outlet of hydrogen of hydrogen storing device. The invention converts each kinds of compound inorganic substances into simple substance which can be used by microbe by decomposing microbe, and generates hydrogen through high efficiency hydrogen generating microbe. Finally, they are converted into electricity energy in fuel battery. It can realizes the controllable conversion between biology mass-energy and electricity energy. It applies to organic waste water discharging industry process and resource utilization, environment protection process to organic waste and water in city environment protection department and resource utilization, and so on.

Description

(1) Technical field [0001] The invention relates to an integrated device for biological hydrogen production and hydrogen energy-electric energy conversion, in particular to an integrated device for hydrogen production and hydrogen energy-electric energy conversion by using microorganisms to ferment organic matter. (2) Background technology [0002] Fossil fuels, including oil, natural gas and coal, form the bulk of today's energy mix. However, fossil fuels such as oil and natural gas are very valuable non-renewable resources, and the proven reserves in the world can only be used for about 50 years according to the current consumption level; on the other hand, the massive utilization of fossil energy has brought serious damage to the environment impact, resulting in air, water and soil pollution. With the development of the economy and society, the human demand for energy continues to increase, and the gap between energy demand and supply will become larger and larger. In o...

Problems solved by technology

The problems existing in the practical process of microbial hydrogen production are mainly manifested in: 1) The efficiency of microbial hydrogen production is low, and the hydrogen production activity of high hydrogen-producing microbial strains reported abroad can reach 26.9mmolH 2 / h·g cell (Kumar N, Das D. Continuous hydrogen production by immobilized Enterobacter cloacae IIT-BT 08 using lignocellular material assolid matrices. Enzyme Microbial Technol, 2001, 29: 280-287), domestic reports that the activity of microbial hydrogen production can reach 24.9 mmolH 2 / h·g cell (Lin Ming, Ren Nanqi, Wang Aijie, etc. High-efficiency hydrogen-producing fermentation bacteria produce hydrogen under the condition of no gas phase. China Biogas, 2002, 20(2): 3-7); 2) The hydrogen production reactor is too Complex or unsatisfactory effect on increasing the hydrogen release rate of the strain; 3) The cost of hydrogen production is expensive

At present, in the research of biological hydrogen production at home and abroad, the main consideration is how to produce hydrogen, but little consideration is given to how to use the hydrogen produced by microorganisms
