NMP (N-Methyl Pyrrolidone) recovery treatment device

The utility model relates to the technical field of NMP treatment, in particular to an NMP recovery treatment device which comprises a tank body, an air inlet and an air outlet are formed in the two sides of the tank body respectively, fluid moves in the direction from the air inlet to the air outlet, and a surface air cooler, a liquid collecting tank and a wire mesh demister are sequentially arranged in the tank body in the moving direction of the fluid. And a turbulent flow mechanism is arranged between the surface air cooler and the wire mesh demister. According to the utility model, the turbulent flow mechanism is additionally arranged in front of the wire mesh demister to disturb fluid in a stable state and promote mutual combination of liquefied NMP vaporific liquid drops, so that the volume is increased, the weight is increased, the liquid drops can directly fall onto the ground more easily, and even if the liquid drops cannot directly fall onto the ground, the liquid drops can be absorbed and drop in
