Problems solved by technology
The salt content in the water affects the power generation work, and it needs to be cleaned regularly, which increases the workload. When the temperature of the condensed water meets the requirements, the salt in the water can be removed more effectively. Therefore, it is also very important to control the water temperature. In reality, special personnel are required to check on time and increase human cost

The present invention proposes an advanced temperature control system for circulating water in a thermal power plant, including a water replenishment tank. One side of the replenishment water tank is provided with a water inlet, and the water inlet is connected to tap water. A salinity sensor is installed on the top of the replenishment water tank, and one end of the salinity sensor is submerged for processing. In water, the top of the water replenishment tank is connected to a liquid medicine valve through a pipeline, one end of the liquid medicine valve is connected to a dosing funnel through a pipeline, one side of the water replenishment tank is connected to a water replenishment pump through a pipe, and the water replenishment pump is connected to a condensate tank through a pipe. A temperature sensor is installed on the top of the water tank, and one end of the temperature sensor is submerged in the condensed water. The condensed water tank is connected to the boiler through the pipeline, the boiler is connected to the generator set through the pipeline, the generator set is connected to the steam pump through the pipeline, and the steam pump is connected to the cooling system through the pipeline. The cooling device is connected to the booster pump through pipelines, and the booster pump is connected to the condensate tank through pipelines. This kind of advanced control system for circulating water temperature in thermal power plants has a simple and reasonable structure, reduces labor costs, and is easy to promote.
Description
technical field [0001] The invention relates to the field of temperature control, in particular to an advanced temperature control system for circulating water in thermal power plants. Background technique [0002] In my country's primary energy structure, coal and other fossil fuels account for more than 70%. Therefore, thermal power plants also account for more than 60% of domestic power generation installed capacity. According to statistics, more than 40% of the world's electricity comes from fossil fuels such as coal. Although the proportion of various renewable energy sources such as wind energy and solar energy is gradually increasing, thermal power plants will still be an important part of the global power industry for a long period of time in the future. [0003] The thermal power generation unit is a complex set of technological processes that convert chemical energy such as coal into electrical energy through thermal energy and mechanical energy. The salt content...
