The invention relates to the technical field of detection, in particular to a vertical dry-wet circulation box device for a corrosive environment. The device comprises a shell; the shell is hollow andis divided into a circulating box and a liquid storage box which are arranged at intervals up and down through a built-in fixed frame; a communicating structure for communicating the circulating boxwith the liquid storage box is mounted on the fixed frame at the bottom of the circulating box; a liquid injection port and a vent hole are formed in the circulating box; the liquid injection port iscommunicated with a water suction pump through a pipeline; the vent hole is connected with an air blower through a pipeline; a liquid outlet is formed in the liquid storage tank; and the liquid outletis communicated with the water suction pump through a pipeline. The device is simple in structure, the occupied space position of the whole experimental device can be reduced through the vertical structure arrangement mode that the circulating box and the liquid storage box are vertically arranged, and rapid flowing of liquid is facilitated through the vertical structure, so the experimental efficiency is improved, and the device has great popularization value.
