[0004] In the above-mentioned adsorption tower, the gas is extracted and sent into the adsorption tower through the air distribution plate.

[0025] Please refer to Figures 1-5 , in the embodiment of the present utility model, an adsorption tower with a variable pressure adjustment structure includes an adsorption tower 4; the top of the adsorption tower 4 is connected with a booster fan 13 in a matching manner, and one side of the adsorption tower 4 is connected with an air extraction fan 3 in a matching manner, and the other end of the air extraction fan 3 is connected with a filter element 2 in a matching manner; a water supply pipe 8 is arranged inside the adsorption tower 4, and a plurality of spray holes 9 are opened inside the water supply pipe 8, and the plurality of spray holes 9 are arranged in a circular array along the central axis of the water supply pipe 8; the water supply pipe 8 is fixed on the spray pipe fixing plate 7 by bolts, and the spray pipe fixing plate 7 is fixed inside the adsorption tower 4 by bolts.

[0026] By adopting the above technical solutions, the air extraction fan 3 adjusts the power to increase the speed of inhaling the flue gas from the filter element 2, and in cooperation with the booster fan 13 above the adsorption tower 4 to increase the pressure, the flue gas inside the adsorption tower 4 is extracted to avoid the situation of accumulation inside the flue gas, and the spray holes 9 of the inner water supply pipe 8 spray and purify the flue gas.

[0027] In this embodiment, a liquid level monitor 10 is fixed on the inner wall of the adsorption tower 4 by bolts, the liquid level monitor 10 is located below the air extraction fan 3, and the liquid level monitor 10 is electrically connected to the drain valve 12.

[0028] Further, the drain valve 12 is cooperatively connected to the drain pipe 11, and the drain pipe 11 is cooperatively connected to the bottom of the adsorption tower 4. Moreover, a bracket 5 is fixed to the outside of the adsorption tower 4 by bolts.

[0029] By adopting the above technical solution, the liquid level monitor 10 detects the liquid level of the sprayed water inside the adsorption tower 4 to prevent it from flowing into the air extraction fan 3. When the liquid level is relatively high, the drain valve 12 opens, and the sprayed water inside will flow out through the drain pipe 11.

[0030] In this embodiment, the water supply pipe 8 is located above the air extraction fan 3, and the water supply pipe 8 is cooperatively connected to the connecting pipe 6, and the other end of the connecting pipe 6 is cooperatively connected to a water pump.

[0031] By adopting the above technical solution, the water pump extracts water and sends it into the water supply pipe 8 through the connecting pipe 6 for spraying. The air extraction fan 3 is located below the water supply pipe 8, which is convenient for the extracted flue gas to be sprayed by water.

[0032] In this embodiment, the other end of the filter element 2 is cooperatively connected with a filter element connecting disc 1, and the filter element connecting disc 1 is connected to the flue gas pipe by bolts.

[0033] Further, one end of the air extraction fan 3 far from the adsorption tower 4 is cooperatively connected with an exhaust pipe 14.

[0035] In this embodiment, an air guide ring 15 is installed on the inner wall of the adsorption tower 4 above the water supply pipe 8, and a plurality of I-shaped rings 16 with different diameters are sleeved inside the air guide ring 15. The cross section of the I-shaped ring 16 is I-shaped and is used for the limiting function at both upper and lower ends.

The spray holes 9 of the water supply pipe 8 inside spray and purify the flue gas; the liquid level monitor 10 detects the liquid level of the spray water inside the adsorption tower 4 to prevent it from flowing into the air extraction fan 3. When the liquid level is high, the drain valve 12 is opened, and the spray water inside will flow out through the drain pipe 11; the water pump pumps water and sends it into the water supply pipe 8 through the connecting pipe 6 for spraying. The air extraction fan 3 is located below the water supply pipe 8 to facilitate the flue gas to be extracted to be sprayed with water; the filter element connection plate 1 facilitates the connection of the flue gas pipe, and the exhaust pipe 14 facilitates the discharge of the flue gas.
