Abstract

The invention belongs to the technical field of energy saving and emission reduction, and specifically relates to a thermoelectric power generation system employing high-temperature exhaust gas. The system comprises a forced-draft gas inflowing device, a heat transfer device, a thermoelectric power generation module, and a cooling water circulation module. The other end of a gas inlet pipe is communicated with a gas inflowing end of a housing gas tank, and a gas discharge end of the housing gas tank is communicated with a gas discharge pipe. The thermoelectric power generation module is made of thermoelectric material which is arranged on the external surface of the housing gas tank regularly. One end of the thermoelectric material contacts with the external surface of the housing gas tank, and the other end of the thermoelectric material contacts with the external surface of a water cooling tank. The cooling water circulation module consists of a water storage tank, a water pump, a first water pipe, a second water pipe, a condenser, and the water cooling tank. The system can make the most of heat of high-temperature exhaust gas for power generation, saves a large amount of energy, and improves the utilization rate of energy.

Description

technical field

[0001] The invention belongs to the technical field of energy saving and emission reduction, and in particular relates to a thermoelectric power generation system utilizing high-temperature waste gas. Background technique

[0002] In actual production and life, there are many situations where high-temperature exhaust gas is discharged. For example, the exhaust gas of vehicles such as automobiles and motorcycles, and the exhaust gas of factory boiler chimneys. The temperature of these high-temperature exhaust gases can reach 500°C to 800°C. At present, these exhaust gases are directly discharged into the air, resulting in a large waste of energy. If the thermal energy of these high-temperature exhaust gases can be fully utilized, on the one hand, the utilization rate of energy can be improved, and on the other hand, the pollution of the high-temperature exhaust gases to the environment can also be reduced.
