flash tank
1、 Flash evaporation principle:
When water is heated at atmospheric pressure, 100 ℃ is the maximum temperature allowed for liquid water at that pressure. Heating again cannot increase the temperature of water, but can only convert it into steam. The heat absorbed by water during the process of heating up to boiling point is called "sensible heat", or the sensible heat of saturated water. The heat required to convert saturated water into steam at the same atmospheric pressure is called "latent heat".
However, if water is heated under a certain pressure, its boiling point will be higher than 100 ℃, so more sensible heat is required. The higher the pressure, the higher the boiling point of water and the higher the heat content. When the pressure decreases, some sensible heat is released, and this excess heat is absorbed in the form of latent heat, causing some water to "flash evaporate" into steam.
2、 The function of flash evaporation tank:
Flash evaporation is the process where high-pressure saturated water enters a relatively low-pressure container, and due to a sudden decrease in pressure, this saturated water is transformed into a portion of the saturated water vapor and saturated water under container pressure. During the transportation of high-temperature and high-pressure condensed water, the pressure changes cause the condensed water to become secondary steam. The generated secondary steam is recovered through a flash evaporation tank to provide steam for low-pressure steam equipment, effectively reducing energy waste. The flash evaporation tank adopts rotary technology to effectively separate the secondary steam and condensed water entering the flash evaporation tank.
