Phase change heat exchanger with self-soot-blowing function

The utility model discloses a phase change heat exchanger with a self-soot-blowing function, which comprises an evaporation section of the phase change heat exchanger and a condensation section of the phase change heat exchanger, wherein the smoke inlet side of the evaporation section of the phase change heat exchanger is provided with a soot-blowing baffle; the soot-blowing baffle is a switching type baffle and comprises 2n blades; two adjacent blades form one group, and n groups are formed and are respectively controlled by n electric actuating mechanisms which are respectively independently operated; each group of blades of the soot-blowing baffle is separated by a diaphragm to form an independent smoke channel. According to the phase change heat exchanger disclosed by the utility model, the smoke inlet side is provided with the soot-blowing baffle, so that a heat exchange element of the evaporation section can be subjected to soot blowing to keep a heated surface clean, and the problems such as the heat e
