Tail acid collecting device in isoleucine extraction process

The utility model provides a tail acid collecting device in an isoleucine extraction process. A glue separating column is connected with at least one tail acid storage tank and at least one stripping liquid storage tank through a stripping liquid pipeline; the tail acid storage tank is connected with a distributor through a circulating pipeline, and the distributor is connected with the glue separating column through a material pipeline; a first electric control valve is arranged in front of the tail acid storage tank, and an electric control valve is arranged in front of the stripping liquid storage tank. The tail acid collecting device in the isoleucine extraction process provided by the utility model can be used for fully recycling isoleucine in the tail acid and utilizing an ammonia solution in the tail acid, so as to reduce the application amount of ammonia water, so that the consumption of raw materials is reduced, no material loss is generated, the product quality is improved, and thus the tail acid collecting device is multipurpose.
