Acrylic acid blending equipment for acrylic hydroxyl ester synthesis

The utility model discloses acrylic acid blending equipment for acrylic hydroxyl ester synthesis, and belongs to the technical field of material mixing equipment. Which comprises a blending tank with a stirring paddle, and is characterized in that a bubble distributor is arranged in the blending tank and is connected with a residual gas recovery pipeline; a feeding port of the blending tank is connected with an acrylic acid constant volume tank arranged at a high position through a pipeline, and a blending discharging port of the blending tank is connected with a metering tank through a pipeline. The constant-volume acrylic acid feeding device can complete constant-volume acrylic acid feeding, does not need calculation of feeding every time, and improves the production efficiency. Excessive ethylene oxide separated by the evaporator is absorbed by acrylic acid in the blending tank, so that material waste is avoided. The prepared acrylic acid is temporarily stored in the metering tank, temporary material prepa
