Embodiment

[0029] At present, limestone-gypsum desulfurization is the mainstream method for removing sulfur dioxide from flue gas in coal-fired power plants, which achieves ultra-low emission requirements of sulfur dioxide. However, with the continuous growth of new energy installed capacity, the power generation load of coal-fired power plants is decreasing year by year. At present, the power generation load of many coal-fired power plants in China is basically about 50%, which is about half of the original design load, or even lower. Generally, power plants have at least two coal-fired generating units, and each unit has an independent desulfurization tower. Each unit operates under low load, and the corresponding desulfurization tower also operates under low load. Therefore, waste of energy is caused.

[0030] To this end, this embodiment provides a desulfurization system capable of reducing energy waste.

[0031] In one embodiment, the desulfurization system includes at least two ...

Abstract

The invention relates to the technical field of environmental protection, in particular to a desulfurization system which comprises at least two desulfurization towers, the two desulfurization towers are the first desulfurization tower and the second desulfurization tower respectively, the first desulfurization tower is connected with a first smoke inlet pipeline and a first smoke outlet pipeline, and the second desulfurization tower is connected with a second smoke outlet pipeline. The second desulfurization tower is connected with a second smoke inlet pipeline and a second smoke exhaust pipeline, the first smoke inlet pipeline is suitable for being connected with a first coal-fired power generation unit, and the second smoke inlet pipeline is suitable for being connected with a second coal-fired power generation unit; the chimney is communicated with the first smoke exhaust pipeline and the second smoke exhaust pipeline; the communicating pipeline is communicated with the first smoke inlet pipeline and the second smoke inlet pipeline; and the first switching structure is arranged at the joint of the communicating pipeline and the first smoke inlet pipeline, and the first switching structure has a first state that the first coal-fired power generation unit is disconnected from the first desulfurization tower and is communicated with the second smoke inlet pipeline through the communicating pipeline.
