Problems solved by technology
However, the problem existing in the existing heat-conducting oil boilers is that the heat discharged by the boiler is directly discharged into the atmosphere, and the temperature of the flue gas is mostly above 100°C. The discharge of these high-temperature flue gases will cause a large amount of heat loss, which causes a great waste of energy.

The invention discloses a boiler flue waste heat recovery and utilization device. The waste heat recovery and utilization device includes a gravity heat pipe and a heat storage tank. The heat storage tank includes a thermal insulation shell and a phase change heat storage material arranged in the thermal insulation shell. The evaporation section of the gravity heat pipe extends into the boiler flue, the condensation section of the gravity heat pipe extends into the heat storage tank, and part of the domestic water circulation pipeline is embedded in the phase change heat storage material. In the present invention, through the heat recovery device, the evaporating section of the gravity heat pipe transfers the heat in the boiler flue to its condensing section, and stores it in the phase change heat storage material. Therefore, it can effectively avoid the loss of heat collected in the phase change heat storage material, and the heat in the phase change heat storage material can heat the domestic water in the domestic water circulation pipeline, saving energy.
Description
technical field [0001] The invention relates to a boiler flue waste heat recycling device, which belongs to the field of boiler structure design. Background technique [0002] The existing heat-conducting oil boiler is a forced circulation boiler. Its working principle is that the low-temperature heat-conducting oil enters the boiler and is heated to become a high-temperature heat-conducting oil, which takes out the heat generated by combustion in the furnace and transfers it to the heat-consuming equipment. Circulation pump circulation heating. However, the problem existing in the existing heat-conducting oil boilers is that the heat discharged by the boiler is directly discharged into the atmosphere, and the temperature of the flue gas is mostly above 100°C. The discharge of these high-temperature flue gases will cause a large amount of heat loss, which causes a great waste of energy. . Contents of the invention [0003] In view of this, the present invention aims to p...
