[0020] like Figures 1 to 4 As shown, the utility model includes a gas-uniform liquid-holding porous bottom plate 1, a supporting wall plate 2 and a turbulent guide vane 3. The top of the porous bottom plate 1 is fixedly connected to the bottom of the turbulent guide vane 3 through the supporting wall plate 2, and the porous bottom plate 1 is installed in the middle position of the existing absorption tower by installing a supporting beam 4.

[0021] In this embodiment, the gas-equilibrated liquid-holding porous bottom plate 1 includes a fixed portion 5 and an opening portion 6, both ends of the opening portion 6 are fixedly connected to the fixed portion 5, a plurality of through holes 7 are evenly arranged on the opening portion 6, and the fixed portion 5 is connected to the mounting support beam 4.

[0022] In this embodiment, the turbulent guide vane 3 includes an end plate 8 and a center plate 9. Both ends of the center plate 9 are connected to the end plate 8. The center plate 9 is composed of a plurality of guide vanes 10 that are inclined, parallel and equidistantly arranged.

[0023] In this embodiment, a spray layer is arranged at the upper part of the absorption tower, and an inlet is arranged at the lower part of the absorption tower, and the inlet is below the gas-homogenizing and liquid-holding porous bottom plate 1 .

[0024] When in use, the flue gas enters through the entrance of the absorption tower, and first passes through the lower spray layer for primary absorption and cooling. The flue gas is quickly cooled and saturated, and a large amount of dust particles and acidic gases are adsorbed. The dust in the saturated flue gas is entrained by water or droplets, and the saturated flue gas passes through the efficiency enhancement device. The flue gas flows evenly through the gas-liquid-holding porous bottom plate 1 below, and turbulent collision is achieved through the turbulent guide vanes 3 above. The absorption and adsorption efficiency is improved by extending the residence time through collision and turbulence, making the slurry in the liquid holding layer more acidic, accelerating the transfer speed of particle components, and increasing the dissolution reaction and adsorption rate; improving the capture efficiency of acidic gases and dust particles, and achieving the flue gas purification effect.

[0025] The utility model can be used in conjunction with a high-efficiency demister to replace the existing deacidification tower + wet electrostatic precipitator, and can effectively reduce the volume of the existing desulfurization tower and reduce water consumption and energy consumption.

[0026] The utility model can realize self-cleaning in the process of flushing reaction between flue gas and absorption slurry, and does not need cleaning facilities. The absorption tower with an efficiency enhancement device can increase the absorption efficiency and dust removal efficiency by more than 25%.

[0027] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any way. Any simple modification, change and equivalent change made to the above embodiment according to the essence of the utility model technology still falls within the protection scope of the technical solution of the utility model.
