Abstract

The invention discloses an annular inlet blade of an SDA desulfurization column. The SDA desulfurizing column comprises a desulfurizing column main body. A gas inlet pipe is arranged at the top end ofthe desulfurizing column body. A plurality of air inlet blades are installed in the air inlet pipe, the bottoms of the air inlet blades are in a conical funnel shape, and the total number of the airinlet blades is 120. Each blade has a folding structure with an included angle of 135 degrees; an atomizing wheel is mounted at the bottoms of the air inlet blades; a flue gas distributor is mounted at the bottom of the atomizing wheel; a conical column is arranged at the bottom end of the desulfurizing column main body. The annular gas inlet blades change the speed and pressure of the original flue gas entering the desulfurizing column, so that the flue gas flow field is changed, and the problem of scaling of a product is improved. By arranging the baffle and the flue structure, the flue gasdistribution ratio of the upper flue and the lower flue is adjusted, and the desulfurization reaction is more sufficient.

Description

technical field [0001] The invention relates to a desulfurization tower blade, in particular to an annular inlet blade of an SDA desulfurization tower. Background technique [0002] As we all know, the desulfurization tower is a tower equipment for desulfurization of industrial waste gas. The desulfurization tower was originally built with granite masonry and was the most widely used. It uses the principle of water film desulfurization and dust removal, also known as granite water film desulfurization dust collector, or granite water film desulfurization dust collector. Dust removal agent, achieve the effect of dust removal and desulfurization (denitrification) at the same time. Now with the development of FRP technology, the desulfurization tower is gradually changed to FRP. Compared with granite desulfurization towers, FRP desulfurization towers are low in cost, easy to process, stainless and non-rotten, and light in weight, so they will become the development trend of d...
