Airflow uniform distribution type wet-method smoke desulfurization and absorption tower

Abstract

The invention provides an airflow uniform distribution type wet-method smoke desulfurization and absorption tower. The airflow uniform distribution type wet-method smoke desulfurization and absorption tower comprises an absorption tower barrel body, wherein a slurry tank is arranged at the bottom of the absorption tower barrel body; a smoke inlet channel is arranged in a barrel wall of the absorption tower barrel body above the slurry tank; a smoke outlet channel is arranged at the top of the absorption tower barrel body; an adsorbent slurry spraying device and a demister are arranged between the smoke inlet channel and the smoke outlet channel from top to bottom; an airflow uniform distribution device is arranged between the adsorbent slurry spraying device and the smoke inlet channel; the airflow uniform distribution device comprises a plurality of flow guide rods which are arrayed horizontally at intervals; the cross section of each flow guide rod is in an inversed V-shaped structure. According to the airflow uniform distribution type wet-method smoke desulfurization and absorption tower, smoke in the absorption tower can be distributed uniformly so that airflow in the absorption tower is effectively rectified, the problem that the partial air speed is too high is solved obviously, the contact area between the smoke and the slurry is enlarged and the contact time between the smoke and the slurry is prolonged; the utilization rate of the slurry is improved; the airflow uniform distribution type wet-method smoke desulfurization and absorption tower has the characteristics of simple structure, low modification cost and the like, is convenient to maintain and is easy to popularize.

Description

technical field [0001] The invention relates to a spray absorption tower in wet flue gas desulfurization equipment, in particular to a wet flue gas desulfurization absorption tower with uniform air distribution. 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 d...
