Abstract
Description
Technical Field
[0001] The utility model provides a dehumidification device for a hydraulic generator chamber, belonging to the technical field of dehumidification of hydraulic generator chambers. Background Art
[0002] Hydropower uses the natural flow of water or its accumulated potential energy to generate electricity. By building dams to intercept rivers to form reservoirs, or by utilizing natural head differences, hydroelectric power stations can convert the kinetic energy of water into electrical energy. When water flows from high to low, it drives the turbine to rotate, which in turn drives the generator to generate electricity. This process is not only clean and environmentally friendly, but can also provide continuous power supply when there is sufficient water resources. It is currently one of the largest renewable energy sources in the world. Hydropower also has the advantage of regulating the balance of supply and demand in the power system, can respond quickly during peak hours of electricity consumption, and supplement the intermittent supply of other renewable energy sources. It is an important part of building a stable and sustainable energy system.
[0003] At present, since hydroelectric generators need water flow to drive, most hydroelectric power generation chambers are set on the water surface. Therefore, the humidity in the chamber is relatively high. High humidity can cause various problems in the generator. Therefore, most hydroelectric power generation chambers use air conditioners, dehumidifiers, ventilation and other methods for dehumidification. When using dehumidifiers, workers are required to drain the water frequently, and in low temperature environments, the water on the dehumidifier evaporator will frost, affecting the operation of the evaporator.
