Abstract
The invention relates to a closed condensed water recovery system, comprising a boiler and a condensed water tank. The upper part of the boiler is in connection with a deaerator through a pipeline; the deaerator is in connection with one end of a soft water tank through the pipeline; the other end of the soft water tank is in connection with a soft water processing exchanger; the soft water processing exchanger is in connection with a tap water inlet pipe; the tap water inlet pipe is in connection with the condensed water tank through a condensation pipeline; a roof of the condensed water tank is respectively in connection with low-pressure steam-consuming equipment, medium-pressure steam-consuming equipment and high-pressure steam-consuming equipment through the pipeline; the roofs of the low-pressure steam-consuming equipment, the medium-pressure steam-consuming equipment and the high-pressure steam-consuming equipment are in connection with a temperature-and-pressure reducer through the pipeline; and the temperature-and-pressure reducer is in communication with the roof of the boiler through a valve. The system is advantageous in that: compared with an opened water recovery system, the system is a closed condensed water recovery system, a flash evaporation loss caused by a decrease in a drainage backpressure can be reduced; the condensed water directly enters into the deaerator with a second flash evaporation and high temperature itself the steam supply amount to the deaerator can be lessened.
