Abstract
The utility model relates to an air lift reactor used for preparing lactic acid, which comprises a cylindrical reactor, an air lift tube connected with gas inlet at the bottom of reactor, a gas distributor at the top of air lift tube, and a mycelium outlet at the bottom of reactor. The utility model is characterized in that the liquid outlet is also arranged at the lower side of reactor and mycelium sedimentation area is arranged between liquid outlet and reactor bottom. In the utility model, mycelium and fermentation liquid can be separated in the interior of reactor to avoid separation process and simplify operation procedure and facilitate the industrialized production.
Description
Technical field
The utility model relates to a kind of reactor, is specifically related to a kind of lactic acid fermented airlift reactor that is used for.
Background technology
Lactic acid is a kind of important chemical, food raw material, is widely used in a lot of fields.Lactic acid generally prepares in fermentation reactor.At present, be used for lactic acid fermented airlift reactor, the product after its fermentation, mycelium and fermented liquid are all discharged by the outlet of reactor bottom, through separating, obtain lactic acid then, and the mycelium after the separation returns reactor.
Adopt the reactor of said structure, operation is comparatively complicated, and working efficiency is lower.Tunning need pass through to separate, and then sends reactor back to.
Summary of the invention
The utility model technical issues that need to address be disclose a kind of be used to prepare lactic acid rise the solid/liquid/gas reactions device, to overcome the defective that prior art exists.
Of the present utility model a kind of be used to prepare lactic acid rise the solid/liquid/gas reactions device, comprising:
Columned reactor;
Be arranged on riser reactor bottom, that be connected with the gas inlet of reactor bottom;
Be arranged on the gas distributor at riser top;
Be arranged on the mycelium outlet of reactor bottom;
It is characterized in that: also be provided with liquid exit in the reactor lower side, be provided with the mycelium negative area between liquid exit and the reactor bottom.
Working method of the present utility model is identical with conventional reactor, but, owing to be provided with liquid exit in the reactor lower side, be provided with the mycelium negative area between liquid exit and the reactor bottom, therefore, in the reaction process mycelium in the negative area sedimentation, liquid is then discharged by liquid exit.
By above-mentioned disclosed technical scheme as seen, of the present utility model be used to prepare lactic acid rise the solid/liquid/gas reactions device, mycelium promptly separates at inside reactor with fermented liquid, has avoided separation circuit, has simplified schedule of operation, is convenient to suitability for industrialized production.
