Description
Technical field
The invention belongs to the synthetic fermentative prodn field of biomass, be specifically related to a kind of biomass synthesis gas fermentative production of ethanol and use equipment.
Background technology
Serious day by day along with energy dilemma, exploitation can replace the renewable and clean energy resource of fossil energy to become the research focus.Alcohol fuel is a kind of substitute energy that application potential is arranged very much, and utilizing the biomass synthesis gas fermentation is a kind of new technology of producing alcohol fuel.
Biomass synthesis gas comes from the Pintsch process gasification of biomass, and staple is CO, H
2And CO
2, steel-making waste gas also can be used as raw material.The biomass source is abundant, and the acquisition of synthetic gas is with low cost, can obtain acetate, ethanol, butyric acid and butanols etc. through anaerobically fermenting.What can utilize the biomass synthesis gas fermentative production of ethanol is one type of special anaerobion, and since the eighties in 20th century, scientists has been found many these quasi-microorganisms successively.One of limiting factor of this fermenting process is a gas-liquid mass transfer efficient, and the fermentation unit that therefore is used to test should have higher rate of mass transfer.
Existing synthetic gas fermentation equipment is more complicated all in design, and cost does not fully take into account the dissolved efficiency of gas than higher, is still waiting further improvement.
Summary of the invention
The purpose of this invention is to provide a kind of biomass synthesis gas fermentative production of ethanol and use equipment.
The present invention adopts following technical scheme:
A kind of biomass synthesis gas fermentative production of ethanol is used equipment; Comprise the reactor drum cylinder; The intravital bottom of reactor column is provided with gas distributor; Be provided with the gas introduction tube that is got into by reactor drum cylinder top in the reactor drum cylinder, the outlet of gas introduction tube is provided with pneumatic outlet and injection port to extending below and pass gas distributor in the both sides of reactor drum cylinder top, gas introduction tube; Reactor drum cylinder bottom is provided with outlet and gas circulation inlet, and the gas circulation inlet passes through pipeline connection with the pneumatic outlet at reactor drum cylinder top.
Gas distributor be provided with ventilating pit, with the identical plectane of reactor drum cylinder inside diameter.
Be equipped with valve on pneumatic outlet, injection port, outlet and the gas circulation inlet.
The import of gas introduction tube is connected with the air outlet of gas-holder,, the air outlet of gas-holder is provided with reducing valve.
Said reactor drum cylinder has a plurality of; A plurality of reactor drum cylinder series connection are provided with; The pneumatic outlet of a last bank of reactor cylinder is connected with the gas introduction tube of next bank of reactor cylinder; So repeatedly, the import of the gas introduction tube of the first bank of reactor cylinder is connected with the air outlet of gas-holder, and the air outlet of gas-holder is provided with reducing valve.
Nutrient solution was got in the reactor drum cylinder by injection port when biomass synthesis gas fermentative production of ethanol of the present invention used with equipment; Again by the gas introduction tube air inlet; Synthetic gas is got in the nutrient solution of reactor drum cylinder bottom through the certain pressure of reducing valve control by gas introduction tube; Synthetic gas receives stopping of reactor drum cylinder to be reduced speed and changes the synthetic gas direction that flows; Synthetic gas upwards further is dispersed into small bubble through gas distributor, and micro-bubble rises in the inner nutrient solution of reactor drum cylinder and is dissolved in the nutrient solution gradually, and then is utilized by mikrobe; Synthetic gas feeds the bottom of reactor drum cylinder earlier, changes into upwards after being stopped by the reactor drum cylinder and flows, and be dispersed into micro-bubble through gas distributor, has prolonged the residence time of bubble in nutrient solution; Form sealed environment in the reactor drum cylinder, certain pressure can be kept in inside, helps the dissolving of synthetic gas in nutrient solution; The synthetic gas that is not absorbed by nutrient solution is discharged by pneumatic outlet and is continued to utilize through inner continuation of gas circulation inlet entering reactor drum cylinder; Finally obtain fermented liquid, detect the ethanol content in the fermented liquid by outlet.
