The invention discloses a waste heat recycling system with a heat pipe exchanger. The waste heat recycling system is mainly composed of a boiler, the heat pipe exchanger, a granite and water film dust remover, a chimney and a heat-preservation water tank. The boiler is a coal-fired boiler and is connected with the lower portion of the heat pipe exchanger through a flue gas pipe. A gas inlet pipe is arranged on one side of the upper portion of the heat pipe exchanger, and the heat pipe exchanger is connected with a blower through the gas inlet pipe; and a gas outlet pipe is arranged on the other side of the upper portion of the heat pipe exchanger, and the heat pipe exchanger is connected with the boiler through the gas outlet pipe. A water inlet pipe and a water outlet pipe are arranged at the top of the heat pipe exchanger, the water inlet pipe is provided with a circulation water pump, and the circulation water pump is connected with the bottom of the heat-preservation water tank through the water inlet pipe. A high-pressure water pump is arranged on the other side of the bottom of the heat-preservation water tank and connected with the boiler through a water pipe. The top of the heat-preservation water tank is connected with a normal-temperature water inlet pipe and the water outlet pipe. The heat pipe exchanger is connected with the granite and water film dust remover through a flue gas pipe. An induced draft fan is arranged behind the granite and water film dust remover and connected with the chimney.
