And (4) storing the condensed water after the exhaust steam is condensed in a hot well below the condenser. In the continuous operation process of the unit, the liquid level of the hot well needs to be stabilized in a certain range (generally 40-80%). Too high and too low liquid level of the hot well can affect the steam exhaust vacuum degree of a unit or the operation condition of a condensate pump.
The existing liquid level adjusting mode is to configure a frequency converter on a condensate pump, adjust the frequency of the frequency converter at any time through an internal program of a control system, and keep the water inlet and the water outlet of a hot well balanced, so that the liquid level is stabilized in a normal range.
However, the waste heat power station is generally small in installed scale, unstable in steam quantity, expensive in price and large in investment due to the adoption of a frequency converter; and the frequency converter has overlarge regulating amplitude, the working condition is not easy to be stable, the frequency converter is also easy to break down, and the problems are urgently to be improved.
