the installation positions of the first box body 2 and the second box body 6 have height difference, and the spontaneous overflow requirement of the first overflow pipe 3 needs to be met; the flue gas to be treated enters the flue gas inlet pipe 1 and is mixed with the liquid absorption medium which is supplemented and entered in the first pipeline 16 and flows into the liquid absorption medium in the first box body 2, wherein the liquid absorption medium which is supplemented and entered into the flue gas inlet pipe 1 plays roles in cooling, extinguishing fire, primary cleaning and the like, the flue gas and the liquid absorption medium which are primarily subjected to wet purification treatment by the liquid absorption medium in the first box body 2 enter the overflow pipe 3 after being filtered by the screen 12 and are mixed with the liquid absorption medium which is supplemented and entered in the second pipeline 17 and flow into the centrifugal pump 4, the gas-liquid mixture which is formed after high-pressure mixing by the centrifugal pump 4 enters the liquid absorption medium in the second box body 6 through the overflow pipe 5, the gas which is subjected to wet purification treatment again passes through the liquid absorption medium in the second box body 6 is discharged out of the gas outlet pipe 6-2, and the mixture formed by the liquid absorption medium and the oil smoke gas in the second box body 6 continuously overflows into the liquid receiving head 18-1 through the liquid level adjusting hose 14 and is discharged out of the sewage treatment plant through the sewage pipe 18 and the sewage pump 19 to be comprehensively treated; the height of the liquid level of the liquid absorption medium in the second box body 6 is adjusted by adjusting the height of the upper port of the liquid level adjusting hose 14.
In the exhaust gas purifying apparatus of embodiment 1, the liquid absorbing medium circularly flows between the first case and the second case, and is suitable for industrial production with small exhaust gas emission; the exhaust gas purifying apparatus in embodiment 2, in which the liquid absorbing medium is continuously monitored and replenished in real time, is suitable for industrial production with large exhaust gas emission.
For different flue gases, the liquid absorbing medium used can be adjusted, for example, the liquid absorbing medium can be alkali-containing solution for absorbing CO and is applied to the exhaust emission treatment of boilers, thermal power generation combustion or other combustion 2 And NO compounds and other toxic substances.
The size and the shape of the first box body and the second box body of the novel self-priming pump are not particularly limited, and the power of the various pump bodies can be customized according to actual use situations.
The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that it will be apparent to those skilled in the art that several modifications and variations can be made without departing from the technical principle of the present utility model, and these modifications and variations should also be regarded as the scope of the utility model.
