The invention relates to a
system and a method for realizing
cogeneration by using a heat-conducting oil furnace and a
semiconductor power generation device. The
system comprises the heat-conducting oil furnace and a
semiconductor temperature difference power generation device connected with the heat-conducting oil furnace through an
oil supply pipeline; an oil-gas separator is connected with thesemiconductor
temperature difference power generation device through a high temperature
heat exchanger; a filter is connected with the heat-conducting oil furnace through a hot
oil pump; a standby hot
oil pump at the low temperature end is connected with a low temperature
heat exchanger; a high-position expansion slot is connected with the oil-gas separator; a low temperature
oil storage slot is connected with the oil-gas separator; in a phase-change working medium condenser of a power generation module, an indirect heat exchange mode is adopted, and cold fluid is used as a
cooling medium forcooling phase-change working medium steam; and the cold fluid is heated and sent into a subsequent section, so the
cogeneration is realized. The invention has the advantages that: high-grade
heat energy is recycled and used, and the
cogeneration is realized at the same time; moreover, as rotating equipment is absent in the
semiconductor temperature difference power generation device, the
system is secure and reliable; meanwhile, an aim that heat-conducting oil furnaces at the same temperature supply heat-conducting oil at different temperatures can be fulfilled.
