In order to realize the utilization of the waste heat of the flue gas and improve the utilization rate of energy sources, the waste heat needs to be recovered. The traditional heat exchanger mainly adopts a tube plate type structure, and has the problems of large volume, large smoke resistance, easy low-temperature corrosion, low operation rate and the like in the waste heat recovery process. The heat pipe type heat exchanger can well solve the problems, the lower part of the heat pipe type heat exchanger is a flue, the upper part of the heat pipe type heat exchanger is a water tank, a steam drum or a water jacket pipe, and the middle of the heat pipe type heat exchanger is separated by a partition plate. The flue gas passes through the flue from left to right, and the cooling water flows to form countercurrent with the flue gas flow direction, improves the heat exchange average temperature, increases the heat exchange quantity. When the heat pipe waste heat recovery device works, the flue gas flows through the flue of the heat pipe waste heat recovery device to wash the lower end of the heat pipe, the working medium at the lower part in the heat pipe absorbs heat and then is changed from liquid state to gas state, the heat absorbing end at the lower part enters the heat releasing end at the upper part, the heat absorbing end is cooled by the cooling water at the outer side of the upper part of the heat pipe and is condensed into liquid state, and the liquid state flows into the heat absorbing end again along the pipe wall, so that circulation is formed, and heat absorption and heat release are continuously carried out. In the prior art, cooling water residues on the outer side of the upper part of the heat pipe cannot be discharged completely, and the pipeline is easily frozen.
