| description | The utility model discloses a pipe shell type spiral baffle plate heat exchanger which comprises a shell, a floating pipe plate, a fixed pipe plate, a heat exchange pipe bundle and a spiral baffle plate. The heat exchange pipe bundle arranged in the shell is fixed between the floating pipe plate and the fixed pipe plate and penetrates through the spiral baffle plate which is coiled on the heat exchange pipe bundle. The utility model is characterized in that space of the periphery of the shell and the heat exchange pipe bundle is additionally provided with a special-shaped heat exchange stage pipe which is fixed between the floating pipe plate and the fixed pipe plate and penetrates through the spiral baffle plate like the heat exchange pipe bundle, and the special-shaped heat exchange stage pipe approaches to the inner wall of the shell. The design is reasonable, the advantages of an existing pipe shell type spiral baffle pipe heat exchanger that pressure is low, and no heat transmission exists are reserved, the short circuit of liquid at the outer side in the shell is prevented, heat exchange area is enlarged, the unstable flow state of the liquid at the surface of the heat exchange pipe is intensified, heat exchange efficiency is improved, and the utility model is an ideal pipe shell type spiral baffle plate heat exchanger. |
