Description

Technical Field

[0001] The utility model relates to the technical field of thermal power supporting facilities, in particular to a thermal power cooling device. Background Art

[0002] A thermal power plant, also known as a coal-fired power plant, is a factory that uses combustibles (such as coal, oil, natural gas, etc.) as fuel to produce electricity. Its basic production process is: when the fuel burns, it heats water to generate steam, converting the chemical energy of the fuel into thermal energy. The steam pressure drives the turbine to rotate, converting the thermal energy into mechanical energy, and then the turbine drives the generator to rotate, converting the mechanical energy into electrical energy.

[0003] When a thermal power plant generates electricity, fuel combustion generates a large amount of heat energy. Part of this heat energy is converted into electrical energy, while the other part needs to be cooled as waste heat. Most of the waste heat is contained in the exhaust gas generated after the fuel is burned. Due to the influence of high temperature, the exhaust gas will bring up more dust and particles. If it is discharged directly, it will affect the external environment and cause air pollution. In order to solve the above problems, when the exhaust gas is discharged, it can be cooled, and the dust and particles contained in it can be purified and filtered, so as to avoid the exhaust gas discharge affecting the external environment of the thermal power plant, which is more convenient for the long-term production and processing of the thermal power plant. For this reason, we propose a thermal power cooling device. Utility Model Content
