Esterification reaction equipment capable of reducing esterification reaction time

Esterification reaction equipment capable of shortening esterification reaction time comprises a pulping tank, a first esterification kettle and a second esterification kettle, the first esterification kettle is communicated with the pulping tank through a slurry conveying pipeline, the second esterification kettle is communicated with the first esterification kettle through a first extraction pipeline, and the second esterification kettle is communicated with a second extraction pipeline. The first extraction pipeline is also communicated with a reflux pipeline communicated with the pulping tank, a reflux control valve is mounted on the reflux pipeline, and an extraction control valve is mounted on the first extraction pipeline at the communication part of the first extraction pipeline and the reflux pipeline; the pulping tank comprises a tank body, a vertically-arranged supporting pipe and lifting equipment used for driving the supporting pipe to move up and down are installed at the top of the tank body, a
