Efficient desulfurization and dust removal spraying device

Abstract

The invention provides an efficient desulfurization and dust removal spraying device. The spraying device comprises a plurality of spraying layers which are sequentially arranged from bottom to top, each spraying layer comprises a slurry circulating mother pipe, a main pipe group communicated with the slurry circulating mother pipe, and a branch pipe group communicated with the main pipe group; the projections of the main pipe groups and the branch pipe groups of the odd spraying layers and the even spraying layers, which are arranged in the spraying empty tower barrel from bottom to top, on the bottom of the spraying empty tower barrel are vertically staggered; the main pipe set comprises an even number of spraying main pipes, the branch pipe set comprises two spraying branch pipes symmetrically arranged on the two sides of the main pipe set, each spraying branch pipe is connected with the nearest spraying main pipe through a flow dividing pipe, connecting pipes are arranged on the two sides or the bottoms of the spraying main pipes and the bottoms of the spraying branch pipes, and the ends of the connecting pipes are connected with nozzles. The desulfurization and dust removal spraying device can reach the ultra-low emission requirement, is low in flue gas resistance energy consumption, few in tower internal components, easy to operate and convenient to maintain, and greatlyimproves the safe operation reliability of a system.

Description

【Technical Field】 [0001] The invention relates to the technical field of desulfurization and dust removal equipment, in particular to an efficient desulfurization and dust removal spray device. 【Background technique】 [0002] Thermal power, iron and steel, metallurgy, cement and other industries are key industries for air pollution control. The wet flue gas desulfurization process is mainly used to remove sulfur dioxide from the flue gas. The desulfurization tower is the most critical core equipment in the wet flue gas desulfurization process system. According to different working principles, it can be divided into spray empty tower, tray tower, venturi grid bar tower, swirling coupling tower, liquid column tower, bubbling tower, packed tower, etc. Compared with other tower types, the spray empty tower has outstanding advantages such as mature and reliable technology, fewer internal components, simple operation, convenient maintenance, and fewer overhauls, so it has been widely u...
