The utility model relates to the field of industrial heat exchange systems, in particular to an efficient tube shell heat exchange device for preparing steam, which comprises a shell, a plurality of inlets and outlets are arranged on the shell, and a plurality of tube plates, a plurality of first tube pass tube bundles and a plurality of second tube pass tube bundles are arranged in the shell. The pipeline is divided into a first pipeline and a second pipeline, the first pipeline is formed by arranging heat exchange pipes composed of three concentric circular pipes, water flows in the innermost-layer pipe, refrigerant flows in the middle circular ring space, water flows in the outer-layer circular ring space, in this way, the refrigerant is clamped between the inner-layer water and the outer-layer water, and the heat exchange effect can be greatly improved; a refrigerant enters the second pipeline from the first pipeline; water enters the shell side from the first pipeline, exchanges heat with the refrigerant
