Description
Technical field
The utility model relates to fermentation equipment, specifically refers to a kind of moving-bed type solid substances continuous fermentation apparatus.
Background technology
China's cellulose family renewable resources is very abundant, annual available stock number reaches 5,000,000,000 tons, only agricultural crop straw just has 700,000,000 tons, but at present except about 200,000,000 tons are used to except the industries such as papermaking, building, weaving, major part is not used appropriately as waste, and idle, heap is abandoned, burn and cause the wasting of resources and environmental pollution.If adopt biomass technical transform to be alcohol fuel 50% wherein; just can obtain the liquid fuel of 500,000,000 ~ 1,000,000,000 tons of oil equivalents; therefore; if suitable technology can be adopted these biomass in addition rational trans-utilization; not only can to save food resource; alleviate energy scarcity, and can also process refuse, elimination public hazards, protection of the environment, this will produce far-reaching influence to the sustainable development of China's economy.
The non-grain biomass such as agricultural crop straw are primarily of Mierocrystalline cellulose, xylogen, hemicellulose and soluble solid composition, and Mierocrystalline cellulose and hemicellulose account for 2/3 to 3/4 of dry weight.Mierocrystalline cellulose is the polymkeric substance of glucose, and its crystalline texture is difficult to be degraded.Hemicellulose is by five-carbon sugar--pectinose, wood sugar; Several different sugar composition such as hexose--glucose, semi-lactosi, sweet dew sugar and sugar acid.Hemicellulose ratio is easier to be degraded into monose.Xylogen has been the complex material of colloid effect, and Mierocrystalline cellulose and hemicellulose link together by it.This energy obtained from non-grain biomass by various technology is then called biomass energy.Change into except liquid fuel after directly burning and biomass being vaporized, non-grain biomass can also change into liquid fuel by many technological approaches again---ethanol.Therefore, the fuel ethanol production technology developing the non-grain biomass such as agricultural crop straw has become the inexorable trend of economy and social development.
The process that fermenting crops straws produces alcohol fuel is divided into 4 steps: 1. pretreatment of fiber element and hemicellulose, removes the material hindering saccharification and fermentation, makes it more easily be degraded and ferment; 2. monose is become with acid or enzymic hydrolysis polymkeric substance; 3. alcohol is become with zymamsis bacterium fermentation hexose with five-carbon sugar; 4. isolation and identification tunning---alcohol fuel.Produce the efficiency of alcohol fuel to improve fermenting crops straws, the large gordian technique of the main pre-treatment around agricultural crop straw, cellulase hydrolysis and fermented bacterium and zymotechnique etc. three conducts a research both at home and abroad.In solid-state stalk fermentation process, due to microorganism growth and breeding in water-fast matrix interface, conveying, the heat transmission and microorganism growth etc. of its nutritive substance have uneven; Oxygen major part simultaneously needed for solid-state stalk fermentation microbial growth and metabolism, from gas phase, also has part be present in the water mixed with solid-state straw substrate and relate to gas, solid, liquid three-phase.In addition, for bio-reactor, solid-state stalk fermentation except the transmission of oxygen be except a restrictive factor, more complicated and prior two parameters are the pH of solid-state straw medium and the water-content of substratum.For this reason, the research and development of a series of modern solid-state stalk fermentation technology such as key equipment and Fermentation Process of Parameter Measurement & Control technology of solid-state stalk fermentation has competitively been carried out recent decades both at home and abroad.
