The invention relates to a novel shell side structure for a
vinyl acetate synthesis reactor. An upper ring-shaped
distributor and a lower ring-shaped
distributor are uniformly disposed at upper and lower ends of the shell side structure along
peripheral directions respectively, the upper ring-shaped
distributor is provided with at least two
discharge ports, the lower ring-shaped distributor is provided with at least two inlet ports, at least two
discharge ports among the at least two
discharge ports are in a flow communicatio with each other through an annular channel arranged in the upper ring-shaped distributor, and at least two inlet ports among the at least two inlet ports are in the flow communication with each other through an annular channel arranged in the lower ring-shaped distributor. A shell and tube
vinyl acetate synthesis reactor comprising the novel shell side structure is further related. By means of the shell side structure and the shell and tube
vinyl acetate synthesis reactor with the same, uniform flow and uniform heat removing of water and steam which serve as heat removing mediums can be achieved in a shell side, the radial
temperature difference of the reactor can be reduced, so that the overall performance of the shell and tube
vinyl acetate synthesis reactor can be improved, the synthesis reaction heat can be reasonably utilized, the operation cost is lowered, and the investment and operation costs of devices of a heat-conducting medium
circulating pump and the like can be reduced.
