Abstract

The invention relates to a synergistic device for a desulfurization absorption tower, belonging to the technical field of smoke gas desulfurization devices. The synergistic device is characterized in that a group of annular hoop cylinders are arranged on the section below a spraying layer and are vertical to the flow direction of smoke gas, the upper part of each annular hoop cylinder is connected with a gas distribution conical plate in an inclined manner, a group of liquid discharge holes are formed in each gas distribution conical plate at intervals, soft sealing components in jacking contact fit are matched between the adjacent annular hoop cylinders and an anti-corrosion layer of a wall plate of the absorption tower through connecting rings constituted by connecting jacking regulating devices and jacking connecting plate components, and conical covers are respectively connected between the adjacent end parts of the gas distribution conical plates. The scheme disclosed by the invention has the advantages of novel concept and reasonable structure, the outer diameter can be easily adjusted according to field actual situations, the mounting process is simple and safe, a gas distribution cone is constituted by communicating multiple sections of inclined gas distribution conical plates, the flow resistance of the smoke gas can not be obviously increased, the smoke gas in the peripheral region in the absorption tower can be re-distributed and can flow to a central region for accumulation, the bypass phenomenon of the smoke gas in the tower can be effectively eliminated, and the smoke gas desulfurization efficiency of the system can be improved.

Description

technical field

[0001] The invention belongs to the technical field of flue gas desulfurization devices, and in particular relates to a desulfurization absorption tower efficiency device. Background technique

[0002] At present, more than 90% of the flue gas desulfurization devices of domestic large-scale coal-fired units adopt the limestone-gypsum wet desulfurization process. In this process, the desulfurization absorption tower of the core equipment basically adopts the spray absorption structure. , there are still some deficiencies in the existing spray design of the absorption tower, mainly in:

[0003] 1) Due to anti-corrosion requirements, the inner wall of the absorption tower is equipped with an anti-corrosion lining. In order to prevent the lining layer from excessive erosion and ensure the service life of the equipment, the arrangement of the spray layer in the tower must consider the anti-scouring safety between the nozzle and the inner wall of the tower Spacing...
