Abstract

The invention provides an energy-saving device for thermoelectric power generation based on a heat distribution pipeline, aiming at problems in a process of conveying a heat working medium through a heat pipe network, great economical loss is caused by the fact that a lot of heat energy is dissipated in the air due to heat radiation of a pipeline. The energy-saving device is composed of twelve parts, namely a positive electrode, a negative electrode, a lead wire, a heat supply pipeline, inner heat-conducting ceramic, a polyurethane filling layer, outer heat-conducting ceramic, a steel hoop, a bolt, a copper electrode, a P type semiconductor and an N type semiconductor. The temperature of the heat working medium conveyed by a heat supply pipeline of a secondary pipe network is commonly more than 80 DEG C and an outdoor average temperature of the North in winter is about 4 DEG C; and a temperature difference between inside and outside of the heat supply pipeline can cause the loss of a lot of heat energy. A semicircular heat-conducting ceramic sleeve is prepared by adopting a pressure casting process and thermoelectric energy conversion semiconductor materials N-Bi2Te3 and P-Bi2Te3 and a copper electrode are pressed and cast between the two ceramic sleeves to form a semiconductor device for the thermoelectric power generation; and 500W generation power can be realized through each meter of the heat distribution pipeline.

Description

technical field [0001] The invention relates to an energy-saving device and method for generating electricity based on temperature difference of a thermal pipeline, belonging to the fields of thermoelectric conversion and waste heat utilization. Background technique [0002] The main way of heating in winter in northern my country is to transfer heat energy to the heating terminal through the thermal power pipe network through the thermal power plant. During the process of transporting hot water or hot steam, about 30% of the heat energy of the heat pipe network is dissipated in the air due to the heat dissipation of the pipes, causing huge economic losses and waste of resources. Therefore, how to make good use of the heat loss of the thermal pipeline has become an urgent problem of energy saving and environmental protection. However, the heat loss of thermal pipelines has the characteristics of low heat flux density, large diffusion area, and long transmission distance, wh...
