Abstract

The invention relates to an ultra-low emission type desulfurization and dust removal rotational flow tray jet tower. The ultra-low emission type desulfurization and dust removal rotational flow tray jet tower comprises a desulfurization tower, wherein a sprinkling system is located on the lower portion of the desulfurization tower, a demister is located on the upper portion of the desulfurization tower, a size rotational flow tray mixer is arranged between the sprinkling system and the demister and located in a rotational flow tray mixer liquid storage tank, the size rotational flow tray mixer comprises a standpipe and a bubble cap, and the standpipe is covered with the bubble cap; multiple tray holes are formed in a tray of the size rotational flow tray mixer. The four desulfurization techniques including sprinkling, rotational flow, tray and bubbling are combined, the characteristics that the rotational flow tray can be used for uniform mixing and a bubbling technique absorbent is of a continuous phase and can achieve deep desulfurization are utilized, and deep desulfurization and deep dust removal are achieved. When the concentration of flue gas SO2 at an inlet of an absorption tower is below 10000 mg / Nm3, the requirement for ultra-low emission that the concentration of SO2 at an outlet is smaller than 35 mg / Nm3 can be met.

Description

(1) Technical field [0001] The invention relates to the field of gas-liquid exchange for waste gas treatment, is suitable for the purification of flue gas desulfurization and dust removal, and particularly relates to an ultra-low emission desulfurization and dust removal swirl tray injection tower. (2) Background technology [0002] As the country's requirements for air pollutant control are getting higher and higher, there are more and more technologies for flue gas pollutant control, forming a diversified technical route for desulfurization and dust removal with ultra-low emissions. However, most desulfurization and dust removal ultra-low emission technology routes have many problems such as high investment, many links, high operating costs, difficult operation, and difficult maintenance. There are also relatively advanced integrated flue gas pollutant treatment technologies, but due to the limitations of various technical parameters, they cannot meet the needs of most use...
