The invention discloses an esterification reaction tower for glyceryl triacetate production. The esterification reaction tower comprises a tower body, a reboiler, a gas distribution plate, a first condenser, a pervaporation membrane separator, a second condenser, a buffer tank, a reflux channel, a gear rack mechanism, a mesh cylinder and a gear motor. According to the invention, water generated bya reaction and a gas-phase azeotrope of a water-carrying agent are rapidly and efficiently dehydrated at the tower top, the removed water is intensively recycled in the buffer tank, and the recycledwater-carrying agent can be sent back to the tower as required and can also be discharged, so that the use is flexible; active carbon in a catalyst in a material can be directly intercepted in the mesh cylinder, so that the filtering difficulty of subsequent procedures is reduced; the mesh cylinder can reciprocate up and down in the tower and continuously rotate, so that the effect of stirring feed liquid is achieved, and the active carbon is dispersed so as to facilitate the reaction; and the feeding door of the mesh cylinder is matched with the reset spring, the upper pressing head and the lower pressing head, so that the functions of automatic feeding, cleaning and discharging can be achieved, and the esterification reaction tower has the advantages of being convenient to operate and maintain.
