Formic acid hydrolysis reactor

The formic acid hydrolysis reactor comprises a tower body, a delivery pump, a liquid pipeline, a liquid inlet, a liquid outlet and an inlet distributor, and further comprises a steam delivery pipeline, a steam recovery pipeline, an inlet pipe, a front pipe box, heat exchange coil pipes, a rear pipe box and an outlet pipe, and a plurality of heat exchange coil pipes are uniformly distributed in the tower body from top to bottom; the heat exchange coil pipe is divided into a front heat exchange area and a rear heat exchange area, the heat exchange coil pipes of the two heat exchange areas are respectively composed of a plurality of coiled pipes which are respectively arranged side by side and are repeatedly bent, through the technical scheme, the plurality of heat exchange coil pipes are arranged in the tower body along the vertical direction, and each heat exchange coil pipe adopts a plurality of coiled pipes which are arranged side by side, so that the temperature difference stress is smaller, and the heat ex
