Blast furnace gas power generation purifying device and treatment method thereof

[0042]A blast furnace gas power generation and purification device of the present invention includes a power generation unit 200 and a purification unit 300; a TRT power generation device 220 is arranged on the power generation main pipeline 210 of the power generation unit 200, and bypasses are connected in parallel at both ends of the TRT power generation device 220 pipeline 240, and the TRT power generation device 220 cools down the gas during the power generation process; the power generation unit 200 in this embodiment is also provided with a temperature regulation controller 230, a flue gas thermometer 214, a TRT power generation device 220, a bypass regulating valve Groups 241 are electrically connected to temperature adjustment controllers 230 , respectively. The flue gas temperature detector 214 is used to detect the temperature of the gas in the pipeline and transmit the temperature signal to the temperature regulation controller 230; Spend. The power generation mai...

[0047] The basic content of this embodiment is the same as that of Embodiment 1, except that the purification unit 300 in this embodiment also includes a liquid storage tank 340 and a purification tank 350. 350, the bottom of the dehydration device 330 is connected to the purification tank 350 through the dehydration drain pipe 331; the purification tank 350 is connected to the liquid storage tank 340 through the purification liquid outlet pipe 351, and the liquid storage tank 340 is connected to the liquid storage tank 340 by spraying the liquid supply pipe 343 The spraying mechanism 315 is connected, the spraying liquid supply pipe 343 is provided with a liquid supply pump 341 , and the spraying liquid supply pipe 343 is provided with a liquid supply valve 342 , and the liquid supply valve 342 is used to control the flow of the spraying liquid supply pipe 343 . The purification tank 350 neutralizes the washing liquid discharged from the tower bottom drain pipe 313, and the ne...

[0050] Refer to attached figure 2 As shown, a blast furnace gas treatment system of the present invention has the same basic structure as in Embodiment 1, except that a U-shaped drain pipe 318 is arranged at the bottom of the reaction tower 310, and the bottom of the U-shaped drain pipe 318 is connected to the purification tank 350 is connected, the height H of the U-shaped drain pipe 318 is greater than 4m, and the U-shaped drain pipe 318 keeps at least 4m of purified water; It is worth noting that when the liquid at the bottom of the reaction tower 310 is discharged into the purification pool 350, due to the large amount of gas in the pipeline, if the gas is not effectively controlled, it is very easy to cause the gas to break through the drainage pipeline. The liquid is leaked into the atmosphere. In this process, the existing technicians often use complex valves or valve groups to control the gas to prevent the gas from leaking into the atmosphere. The applicant of the p...
