Problems solved by technology

When the mash concentration is too high, take the mash prepared from corn starch as an example. In the existing field, for example, in the process of producing butanol by fermenting corn starch, if the weight concentration of corn starch is greater than 8.5%, due to the large amount of butanol produced When the butanol concentration reaches the maximum value of 10

Abstract

The invention belongs to the technical field of producing biological butanol by fermentation, which relates to a method and a device for producing the biological butanol by extracting and fermenting starch substances and sugar substances. The method comprises the following steps: discharging fermented liquor from a last fermentation tank; then feeding the fermented liquor into a next fermentation tank for continuous fermentation; adding an extracting agent to be mixed for extracting butanol in the bulking tank and conveying process of feeding the fermented liquor from the last fermentation tank to the next fermentation tank; extracting and separating the butanol generated by the fermented liquor with the extracting agent; and feeding the fermented liquor separated from a mixture of the extracting agent and the butanol into the next fermentation tank for fermentation. The invention realizes the method and the device for producing the biological butanol by the continuous extraction and fermentation. The biological butanol can be produced by a method for continuously adding the extracting agent, continuously separating the biological butanol and continuously supplementing original fermented liquor. The invention can improve the yield of the biological butanol by 3 times to maximum extent, save one second of steam, reduce the discharge of over 60 percent of wastewater and bring considerable economic benefits to enterprises for producing the biological butanol.

Description

technical field [0001] The invention belongs to the technical field of fermentation production of bio-butanol, and relates to a method and a device for continuously extracting and fermenting starchy substances and sugar substances to produce bio-butanol. Background technique [0002] Bio-butanol refers to butanol produced through biological fermentation using existing biological resources. Butanol is widely used in organic synthetic plastics, resins, paints, medicine and defense industries. In addition to being used as a solvent, butanol is also a potential large-scale power fuel. Its combustion value is equivalent to that of gasoline, and it is a substitute for automobile oil. The existing bio-butanol production process is to sterilize starchy substances or carbohydrates after hydrolysis of cellulose at high temperature, and then connect Clostridium acetobutylicum, Butyricum acetobutylicum, Clostridium saccharobutyricum or Clostridium pasteurianus Produced by fermentation...
