Description
Technical Field
[0001] The invention relates to the technical field of thermal power plant equipment, and in particular to a water cooling device for a thermal power plant. Background Art
[0002] A thermal power plant is referred to as a thermal power plant. The 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 steam turbine to rotate, converting the thermal energy into mechanical energy. The steam turbine then drives the generator to rotate, converting the mechanical energy into electrical energy. Among them, the high-temperature steam drives the steam turbine and is then cooled for use, which requires the use of a cooling device.
[0003] At present, the existing water cooling devices for thermal power plants on the market usually simply cool the high-temperature steam after work by spraying coolant. However, in actual use, due to the short contact time between the coolant and the high-temperature steam, the time for heat exchange between the coolant and the high-temperature steam is short, resulting in low heat exchange efficiency, which in turn leads to poor cooling effect, which has a certain impact on later utilization. This heat exchange method leads to a large amount of evaporation water loss. However, the shortage of fresh water resources is an important problem facing the world today. Thermal power companies are large water consumers. The cooling towers of the conventional wet cooling system currently used discharge a large amount of water to the environment through evaporation while cooling the circulating water. The energy consumption of water cooling devices is high. This is because during operation, there must be a certain amount of excess energy (20%-25%) in the circulating water system. This energy may accumulate at a certain valve after a long period of operation, eventually leading to unnecessary loss of energy.
[0004] In general, the energy consumption of water cooling devices in thermal power plants has always been a technical problem in the relevant field. The key to solving this problem may lie in how to more effectively utilize and convert this excess energy. Summary of the invention
