Problems solved by technology

Through the observation in the actual project, it is found that the solution is sputtered after the spray slurry is in contact with the tube-grid synergistic device, and it is difficult to form a stable liquid film, which is not conducive to the further improvement of the desulfurization efficiency.

Embodiment 1

[0036] like Figure 1 to Figure 4 As shown, the present invention provides a high-efficiency and low-resistance synergistic device for a desulfurization tower, at least one layer of turbulent columns is provided, and the turbulent columns are installed at the inlet of flue gas to be desulfurized through a mounting bracket 1, and installed on the Spray layer spray area;

[0037] The spoiler row includes a disturbing flow member 2, the cross section facing the desulfurization slurry spraying direction is a semi-circular arch, and the semi-circular arch is provided with a through hole 3 through which the flue gas and desulfurization slurry can pass, and the cross-section of the spoiler 2 is is semicircular.

[0038] The spoilers 2 on the same spoiler row are evenly distributed;

[0039] The through holes 3 are evenly distributed on the spoiler 2 .

[0040] The diameter of the semicircular section of the spoiler 2 is D, the gap between two adjacent spoilers 2 on the same spoile...

Abstract

A high-efficiency and low-resistance synergistic device for a desulfurization tower of the present invention is provided with at least one layer of turbulence columns, and the turbulence columns are installed at the entrance of the flue gas to be desulfurized through a mounting bracket, and installed on the spray layer to spray area; the turbulence column includes if there are disturbing flow parts, the section facing the desulfurization slurry spraying direction is a semi-circular arch, and the semi-circular arch is provided with a through hole through which both the flue gas and the desulfurization slurry can pass. is semicircular. The invention proposes a desulfurization synergist with a new structure, which can prevent slurry from splashing while ensuring low resistance in operation, and effectively forms a liquid film layer on the surface of the synergist.

Description

technical field [0001] The invention relates to the technical field of desulfurization, in particular to a high-efficiency and low-resistance synergistic device. Background technique [0002] my country is a big coal-fired power generation country, and the environmental problems caused by coal-fired power plants have been paid more and more attention. In recent years, the country's requirements for waste emissions have become more and more stringent. my country's new "Emission Standard of Air Pollutants for Thermal Power Plants" (GB13223-2011) has been implemented since 2015. Most power plants are facing more stringent environmental protection requirements, and some economically developed regions require power plants to achieve near-zero emissions. At present, my country's coal-fired power plants use more SO 2 The treatment technology is wet desulfurization, mainly limestone-gypsum method. Although the effect of calcium-based wet desulfurization is remarkable, considering ...
