Example Embodiment

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0019] The high-quality wet flue gas desulfurization spray absorption tower shown in the figure includes a spray tower cylinder 8, and the lower and upper parts of the spray tower cylinder 8 are respectively provided with a flue gas inlet channel 1 and a flue gas outlet channel 7, The connection between the upper part of the flue gas inlet channel 1 and the spray tower body 8 is a chamfered or arc-shaped smooth transition structure, and the connection between the lower part of the flue gas inlet channel 1 and the spray tower body 8 is 10~20° from the horizontal plane. Slope to avoid crystallization or scaling here. Between the flue gas inlet channel 1 and the flue gas outlet channel 7, a slurry spray device 4 and a mist eliminator 5 are horizontally arranged from bottom to top, and a porous sieve plate is horizontally arranged between t...

Abstract

The invention discloses a high-quality spray absorber for wet flue gas desulfurization. The absorber comprises an absorber cylinder body which is provided with a flue gas inlet channel and a flue gas outlet channel. A perforated screen plate, flue gas redistribution rings, slurry spray devices, a demister and a rotating-stream plate device are arranged horizontally from bottom to top between the flue gas inlet channel and the flue gas outlet channel. Inner side edges of the flue gas redistribution rings are in an undulate or serrated shape, and the rotating-stream plate device is composed of a plurality of evenly-distributed independent rotating-stream plate separators. According to the high-quality spray absorber for wet flue gas desulfurization, the problem of no flue gas flowing above the absorber close to the flue gas inlet section is solved, the phenomenon of the easy crystallization and scaling of the area is overcome, gas-liquid contact area is maximized, absorption reaction is effective, and the absorber is applicable to desulfurization of flue gas with high sulfur dioxide content. 'fog-drop particles' carried in the flue gas are eliminated to the maximum extent, chimney 'rain' phenomena are reduced greatly, and the content of fog-drop particles can achieve 60 milligrams/nanometer3. The absorber is wide in applicable range, and can be used for wet flue gas desulfurization in a double-alkali way, an acetylene sludge way, a lime-gypsum way and the like.

Description

technical field [0001] The invention relates to a spray absorption tower in wet flue gas desulfurization equipment, in particular to a high-quality wet flue gas desulfurization spray absorption tower. Background technique [0002] The acid rain problem is one of the global environmental problems facing mankind today. The sulfur oxides SO produced by coal burning 2 and nitrogen oxides NO x Pollution is the main protozoa of acid rain in my country. Since my country's energy structure is dominated by coal, in my country's power industry, thermal power has always accounted for about 70% of the total power generation, and coal-fired power plants are the largest source of air pollution in my country. Controlling the flue gas pollution of power plants is the requirement to realize the coordinated development of economy, society and environment, and it is also the requirement to give full play to the advantages of my country's coal reserves and realize the sustainable development ...
