Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall be included within the scope of protection of the present invention.
In the specific embodiment, as shown in fig. 1 and 2, a flue gas desulfurization turbulator device is arranged in a tower body of a desulfurization tower and located between a spraying mechanism and an inlet flue, the turbulator device comprises a positioning plate 1, a group of turbulating holes 2 arranged on the positioning plate 1, and a turbulating unit 3 arranged in the turbulating holes 2, the turbulating unit 3 comprises an inner cylinder 3-1 coaxially arranged with the turbulating holes 2, and a group of swirl blades 3-2 fixed between the outer wall of the inner cylinder 3-1 and the hole wall of the turbulating holes 2, all the swirl blades 3-2 are uniformly arranged in the circumferential direction of the inner cylinder 3-1 and are all obliquely arranged, and a flue gas channel is reserved between the adjacent swirl blades 3-2.

As a further improvement of the utility model, the porosity of the turbulence holes 2 in the locating plate 1 is 40-60%. The flue gas flow line of turbulator device top becomes more smooth and easy, the anticlockwise swirl grow of turbulator device below, and increase along with the increase of turbulator device porosity, this is because the inflow flue gas easily produces decurrent speed after striking tower wall and turbulator device, the part flue gas that is detained below the turbulator device forms anticlockwise swirl under the influence of 6 high-speed flue gases of entry flue, when 3 diameters of turbulence unit are fixed, increase turbulator device porosity, the through-flow sectional area of flue gas increases, the high-speed flue gas that enters in the tower upwards flows more, the impact influence of detaining the flue gas below the turbulator device weakens, cause the regional increase of the anticlockwise swirl that the flue gas formed of detaining. The anticlockwise vortex causes the flue gas to carry water, which can cause the corrosion of the inlet flue 6 and influence the overall desulfurization efficiency of the desulfurization tower, so that the installation of the turbulator device with proper porosity has important influence and effect on improving the uniformity distribution of the flow field in the tower and controlling the flue gas to carry water. When the porosity of the turbulent hole 2 on the positioning plate 1 is 50%, the effect between the flue gas and the slurry is more facilitated, and the desulfurization efficiency is improved.

When the diameter of the turbulence unit 3 is reduced when the porosity is constant, the anticlockwise vortices below the turbulator device become larger and tend to move towards the inlet flue 6, which also causes corrosion of the inlet flue 6, which is extremely disadvantageous for in-tower desulfurization. When the porosity is constant (e.g. 50%), the flow field over the turbulator device becomes more uniform and smooth as the diameter of the turbulence unit decreases, since when the porosity is constant, the number of openings tends to increase as the diameter of the turbulence unit 3 decreases, and the rectifying effect of the turbulator device increases. When the ratio of D1 to D2 is 13: 1.0, or 13: 1.2 the flow field in the tower is more uniform and stable, which is beneficial to improving the mass transfer efficiency between the slurry and the flue gas in the tower and the utilization rate of the slurry, reducing the operation load of the circulating pump 11, further reducing the operation cost and improving the benefit.
