At present, a plurality of 1/4 fan-shaped flat plates are connected alternately instead of curved surfaces to form an approximate spiral surface.
Although the processing technology of the discontinuous helical baffle is mature and popularized and applied in the petrochemical industry, the discontinuous helical baffle still has a plurality of defects. For example, the joints of the fan-shaped plates form unsmooth acute-angle transitions, back pressure exists on axially moving fluid, energy loss is caused by sudden turning of the fluid when the fluid passes through, and energy consumption is more serious when the helix angle is larger; the spiral curved surface has a serious triangular leakage area, so that the flow of the shell pass fluid deviates from the spiral flow, and the shell pass heat transfer performance is reduced.
