Abstract

The invention relates to a quick waste liquid recycling device and belongs to the technical field of waste liquid recycling. The quick waste liquid recycling device comprises a separation tank and a recycling tank connected with the separation tank. A cooling device is arranged between the separation tank and the recycling tank. A stirring device and a heating device are arranged in and out of the separation tank respectively. The quick waste liquid recycling device is characterized in that a heat conductive part connected with the inner wall of the separation tank is arranged below the stirring device in the separation tank, the heat conductive part is in a screen shape, and holes are formed in the heat conductive part. The waste liquid recycling device is quick to operate and saves time cost.

Description

technical field [0001] The invention relates to the technical field of waste liquid recovery, in particular to an energy-saving waste liquid recovery device. Background technique [0002] In the process of producing dihydrophenylglycine sodium salt, the finished product is obtained by centrifugation and drying. The generated methyl isobutyl ketone after centrifugation contains a small amount of methanol. In order to ensure the performance of methyl isobutyl ketone, it is necessary to Methyl isobutyl ketone is washed and recovered. [0003] In the prior art, sodium chloride solution is used to react with the mixed solution of methyl isobutyl ketone and methanol, then the methanol located in the lower layer of the solution is discharged, and the methyl isobutyl ketone above the solution is evaporated by heating and then condensed and recovered. [0004] However, the heating conduction efficiency in the prior art is not high, and the rate of heat conduction to the center of th...
