Description
Technical field
The utility model relates to a kind of biological fermentation reaction unit, relates in particular to a kind of air lift type circulation complex ferment reactor, mainly is applicable to by biological fermentations such as methyl alcohol system methyl alcohol albumen and reacts.
Background technology
China's feed industry needs methyl alcohol albumen about more than 5,000,000 tons every year at present.And the industry of present domestic methyl alcohol albumen still is in the starting stage, does not set up production equipment as yet.Therefore, the simple fish meal that relies on farm crop such as plantation grain class or marine fishery production satisfies the mankind and far can not satisfy the growing market requirement to proteinic demand.Synthetic single cell protein (single cell protein) is one of important channel that solves China's food problem.And the methyl alcohol single cell protein can be a raw material from coal or Sweet natural gas, makes via the methyl alcohol biochemical reaction.It contains rich in protein, amino acid and multivitamin, and product safety and nontoxic can promote livestock to produce and improves efficiency of feed utilization.Owing to produce traditional mode of production pattern and marine fishery resources that methyl alcohol albumen need not rely on the arable land, with methyl alcohol is that raw material synthesizing methanol albumen is as high-octane concentrated feed, per 1 ton of methyl alcohol albumen can be saved 3.5 tons in grain, can prepare 10 tons of feeds, and social benefit and economic benefit are all very considerable.So development methyl alcohol albumen is one of important channel that solves China's aquaculture and foodstuffs industry protein shortage problem.
In the prior art, gas-lift fermentation reactor is the novel fermentation reactor of introducing from Chemical Manufacture in the fermentative production, and the gas-lift fermentation reactor of research is only limited to two kinds of base types at present both at home and abroad: internal-circulation type and outer circulation type.Basic functional principle is: with the reaction of internal-circulation type aerobic fermentation is example, power and the buoyancy lift of air in liquid of utilizing air to spray into, at the logical people's air of reactor bottom and adding fermented liq raw material and nutrition, power that sprays into air and buoyancy lift promote air and the mixed gas of liquid material, rising, and circulating about forming, at round-robin simultaneously, bubble in liquid stirring and sieve plate to the continuous fragmentation of bubble, airborne oxygen is dissolved in the liquid fully, satisfies mass transfer, heat transfer between required oxygen supply of fermentation and solid-liquid.Its major parts of internal-circulation type structure: aeration jet, gas-liquid rising area circulating barrel, fermentation tank body, jacket heat exchanger, opening for feed, discharge gate.Because this gas-lift fermentation reactor gas-to-liquid contact weak effect, make the dissolved oxygen in the fermented liquid fail to guarantee effectively microorganism growth and the metabolic requirement of product, what is more important can not be timely, cause interior temperature of fermentor tank and homogeneity thereof not to be effectively controlled, thereby causing product productive rate and extract yield low, fermentor tank can only be selected for use on a small scale, the tank body of small volume.
