Heat-pipe thermoelectric power generation energy storage and power transmission system for rear smoke channel of boiler

The invention relates to a heat-pipe thermoelectric power generation energy storage and power transmission system for a rear smoke channel of a boiler, and the system comprises a thermoelectric power generation system, an energy supply system, and an energy storage system. A thermoelectric power generation unit in the thermoelectric power generation system comprises a cold-end heat pipe device, a hot-end heat pipe device and a thermoelectric power generation piece disposed between the cold-end heat pipe device and the hot-end heat pipe device, wherein the cold-end heat pipe device and the hot-end heat pipe device are vertically arranged in a structure. The thermoelectric power generation piece is disposed on the rear smoke channel, and the hot-end heat pipe device of the thermoelectric power generation unit makes contact with the high-temperature flue gas to absorb heat, and maintains the high temperature of the hot surface of the thermoelectric power generation piece. The cold-end heat pipe device makes contact with the ambient atmosphere, and maintains the low temperature of a cold surface of the thermoelectric power generation piece. A direct current generated by the thermoelectric power generation system is converted and then is outputted to an electric appliance. Meanwhile, the redundant electric energy is directly stored in the energy storage device. Two ends of the thermoelectric power generation piece form a big temperature difference through the high-efficiency thermal conduction characteristics of a hot pipe, thereby improving the power generation efficiency of the thermoelectric power generation piece. The hot pipe is changed to be elliptical, thereby effectively reducing the wear, caused by solid particles, of the hot pipe.
