[0017] In order to make the content of the present invention more clearly understood, the present invention is further described in detail below according to specific implementation modes and in combination with the accompanying drawings.

[0018] Figure 1 A schematic diagram of a converter vaporization flue saturated steam power generation device provided in an embodiment of the present application. The device includes a converter vaporization system, a heat accumulator 3, a steam-water separator 4, a turbine unit 8, a generator unit 9, and a condenser 11. The discontinuous and pressure-unstable converter saturated steam is first stabilized in the heat accumulator 3, and then separated into steam and water through the steam-water separator 4 to obtain stable, water-free steam. These stable dry steams are sent to the turbine unit 8 through a pipeline to generate power, which can ensure the reliable and safe operation of the generator unit 9.

[0019] Specifically, the outlet end of the converter vaporization system is connected to the inlet end of the heat accumulator 3 through a steam pipeline, and the steam generated by the converter vaporization system enters the heat accumulator 3 through the steam pipeline for pressure stabilization.

[0020] In this embodiment, the working pressure of the heat accumulator 3 is 0.4 MPa~2.0 MPa.

[0021] Preferably, a steam inlet check valve 1 is provided on the steam pipeline between the converter vaporization system and the heat accumulator 3, and the installation direction of the steam inlet check valve 1 is the steam inlet direction of the heat accumulator 3, that is, the medium flow direction in the steam inlet check valve 1 is from the converter vaporization system to the heat accumulator 3. The steam inlet check valve 1 can prevent the steam in the heat accumulator 3 from flowing back into the converter vaporization system.

[0022] The outlet end of the heat accumulator 3 is connected to the inlet end of the steam-water separator 4 through a steam pipe, and the steam in the heat accumulator 3 enters the steam-water separator 4 through the steam pipe to separate the steam and water, thereby forming stable steam without water.

[0023] Preferably, a steam outlet check valve 2 is provided on the steam pipeline between the heat accumulator 3 and the steam-water separator 4, and the installation direction of the steam outlet check valve 2 is the discharge direction of the heat accumulator 3, that is, the flow direction of the medium in the steam outlet check valve 2 is from the heat accumulator 3 to the steam-water separator 4. The steam outlet check valve 2 can prevent the steam in the steam-water separator 4 from flowing back into the heat accumulator 3.

[0024] The outlet of the steam-water separator 4 is connected to the inlet of the turbine unit 8 through a steam pipeline, and a steam inlet speed shut-off valve 6 and a steam inlet regulating valve 7 are sequentially arranged on the steam pipeline between the steam-water separator 4 and the turbine unit 8. Figure 1 The steam inlet speed shut-off valve 6 is located between the steam-water separator 4 and the steam inlet regulating valve 7. The dry steam after being diverted by the steam-water separator 4 enters the turbine unit 8 through the steam pipeline to perform work. The steam inlet speed shut-off valve 6 can control the on-off of the steam pipeline between the steam-water separator 4 and the turbine unit 8. The steam inlet regulating valve 7 can adjust the flow rate of steam in the steam pipeline between the steam-water separator 4 and the turbine unit 8.

[0025] Preferably, a flow meter 5 is provided on the pipeline between the steam-water separator 4 and the steam inlet speed shut-off valve 6 , and the flow meter 5 is used to record the steam flow in the pipeline between the steam-water separator 4 and the steam inlet speed shut-off valve 6 .

[0026] The generator set 9 is connected to the turbine set 8. The turbine set 8 drives the generator set 9 to generate electricity under the driving of steam.

[0027] The inlet end of the condenser 11 is connected to the outlet end of the turbine unit 8 through a steam pipe, and a vacuum pump 10 is connected to the condenser 11 through a pipe. After the steam works in the turbine unit 8, exhaust steam is formed and enters the condenser 11 to condense into water. At the same time, the outlet end of the condenser 11 is also connected to a condensate pump 12 through a pipe, and the condensate pump 12 can transport the condensed water formed in the condenser 11 to the soft water system for recycling.

[0028] Therefore, the technical solution of the present application can convert the saturated steam of the converter vaporization flue with unstable and discontinuous pressure into saturated steam with stable pressure, which is used for power generation by the turbine unit 8 to ensure the reliable and safe operation of the generator unit 9.

[0029] In addition to the above embodiments, the present invention may also have other implementation modes; any technical solutions formed by equivalent replacement or equivalent transformation shall fall within the protection scope required by the present invention.
