When the gas passes through the liquid absorption net 10, the liquid drops carried by the gas surface are absorbed by the activated carbon 101, and the gas is discharged from the gas outlet 12 through the liquid absorption net 10, so that the effect of removing foam is achieved.
As a specific embodiment of the invention, the periphery of the tower body 1 is fixedly connected with a flange 15, and the flange 15 is communicated with a cavity formed by two liquid suction nets 10.
Because the adsorption property of the activated carbon 101 in the two liquid absorption nets 10 may be reduced after the activated carbon 101 adsorbs liquid drops carried on the gas surface for a long time, the invention arranges the flange 15 at the periphery of the tower body 1, and replaces the activated carbon 101 in the two liquid absorption nets 10 by the flange 15, so that the liquid absorption nets 10 achieve the effect of good liquid absorption for a long time.

Because the time of the interphase mass transfer required by different gases and liquids is different, the invention controls the air input of the gases through the throttle valve 16, thereby controlling the rotating speed of the stirring shaft 2, if the time of the interphase mass transfer required by the gases and the liquids is shorter, the rotating speed of the stirring shaft 2 is slower, thereby reducing the flow of the gases; if the time of the interphase mass transfer required by the gas and the liquid is longer, the rotating speed of the stirring shaft 2 is faster, so that the flow of the gas is increased, and the interphase mass transfer effect suitable for different gases and liquids is achieved.
The working principle is as follows: the packing 9 in the traditional lightness-removing tower is mostly placed on the supporting plate in a random or whole-building mode, the positions between the adjacent packing 9 are relatively fixed, so when liquid flows through the packing 9 layer from top to bottom, a liquid film with a certain thickness is spread on the outer surface of the packing 9, gaps are formed between the packing 9 and the packing 9 in the packing 9 layer, and when gas passes through the gaps from bottom to top, the gas can be contacted with the liquid film on the surface of the packing 9 so as to carry out interphase mass transfer, because the positions between the adjacent packing 9 are relatively fixed, the size of the liquid film spread on the outer surface of the packing 9 is always constant, and the gaps between the packing 9 are also constant, so that the amount of the gas passing through the gaps between the packing 9 is constant, in order to solve the problem, the invention conveys high-pressure gas into the gas inlet pipe 4, and then the gas inlet pipe 4 blows towards the fan blades 3 through the gas inlet 11 so as to rotate the fan blades 3, because the fan blades 3 are fixedly connected with the stirring shaft 2, the fan blades 3 drive the stirring shaft 2 to rotate, the stirring shaft 2 stirs the filler 9 between the first partition plate 5 and the second partition plate 8, meanwhile, the liquid flows into the liquid inlet pipe 7 from the liquid inlet 13 and then enters the liquid inlet groove 53 in the first partition plate 5 through the connecting pipe 6, the liquid is sprayed into the layer of the filler 9 through the liquid spraying hole 52, because the stirring shaft 2 is fixedly connected with the first partition plate 5, the stirring shaft 2 drives the first partition plate 5 to rotate, the sprayed liquid is subjected to a certain centrifugal force, the liquid is sprayed more uniformly, high-pressure gas enters the layer of the filler 9 through the air holes 81 on the second partition plate 8 after blowing the fan blades 3, because the air holes 81 are unidirectional, the gas can only pass from bottom to top, the gas can not flow back, when the filler 9 flows to the layer of the filler 9 because the stirring shaft 2 stirs the filler 9, the area of the liquid film formed on the outer surface of the filler 9 is larger, so that a mass transfer surface with a larger area is provided, meanwhile, as the filler 9 is stirred, the gap between the filler 9 is also enlarged, so that more gas is transferred on the filler 9, and the efficiency of the lightness removing tower is further improved, as the stirring shaft 2 simultaneously stirs the filler 9, the liquid and the gas, the interphase mass transfer between the liquid and the gas is more sufficient, the mass of the gas and the liquid after lightness removing of the lightness removing tower is improved, after the mass transfer is finished, the gas is discharged from the gas outlet 12 through the vent hole 51 in the first partition plate 5, the liquid flows into the liquid outlet groove 83 through the liquid outlet hole 82 on the upper surface of the second partition plate 8, and the liquid flows into the liquid outlet 14 on the tower body 1 through the liquid outlet groove 83 and is discharged through the liquid outlet 14.
When gas is blown into the filler 9 layer, uneven blowing can occur, and the gas and the liquid can be uniformly sprayed into the filler 9 layer simultaneously when the fan blades 3 are blown by arranging the gas inlet holes 22 in the stirring shaft 2 and the rotating shaft 214, so that the effect that the gas and the liquid can carry out interphase mass transfer more quickly and sufficiently is achieved.
When the gas passes through the liquid absorption net 10, the liquid drops carried by the gas surface are absorbed by the activated carbon 101, and the gas is discharged from the gas outlet 12 through the liquid absorption net 10, so that the effect of removing foam is achieved.
Because the adsorption property of the activated carbon 101 in the two liquid absorption nets 10 may be reduced after the activated carbon 101 adsorbs liquid drops carried on the gas surface for a long time, the invention arranges the flange 15 at the periphery of the tower body 1, and replaces the activated carbon 101 in the two liquid absorption nets 10 by the flange 15, so that the liquid absorption nets 10 achieve the effect of good liquid absorption for a long time.
In order to blow the fan blade 3 better, a first air injection hose 41 and a third air injection hose 43 are respectively arranged in the air inlet pipe 4 in the vertical opposite directions, the first air injection hose 41 and the third air injection hose 43 are aligned with the fan blade 3 to blow air, so that the fan blade 3 is easier to rotate, and a second air injection hose 42 positioned between the first air injection hose 41 and the third air injection hose 43 is aligned with an air inlet hole 22 on the stirring shaft 2 to directly blow air into the air inlet hole 22 and blow the air into the layer of the filler 9 through the air inlet hole 22.
Because the time of the interphase mass transfer required by different gases and liquids is different, the invention controls the air input of the gases through the throttle valve 16, thereby controlling the rotating speed of the stirring shaft 2, if the time of the interphase mass transfer required by the gases and the liquids is shorter, the rotating speed of the stirring shaft 2 is slower, thereby reducing the flow of the gases; if the time of the interphase mass transfer required by the gas and the liquid is longer, the rotating speed of the stirring shaft 2 is faster, so that the flow of the gas is increased, and the interphase mass transfer effect suitable for different gases and liquids is achieved.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the invention as claimed.
