Automatic flushing device for regeneration tank overflow weir

Abstract

The invention relates to an automatic flushing device for a regeneration tank overflow weir, and is characterized in that an outlet pipeline of a barren liquor pump (8) is additionally connected with a pipeline flushing header pipe (1); the flushing header pipe (1) is provided with an electromagnetic control valve (2); a distribution pipe (3) is arranged in a 360 degree annular direction parallel to the overflow weir (6); the distribution pipe (3) is provided with a plurality of branched pipes (5); the inner side of the overflow weir (6) is provided with an overflow weir flushing pipe (4) in 360 degree annular direction; a plurality of small holes are evenly distributed in the overflow weir flushing pipe (4). The current situations of high suspended sulfur of an alkali liquor system, large manipulation intensity and difficult control caused because a regeneration tank overflow weir of a desulfurization system is often blocked by sulfur foams are solved, fluctuation of a liquid level caused by frequent sulfur scraping and frequent adjustment is reduced, and alkali liquor regeneration and sulfur foam generation effects are affected, so that the fluctuation of the liquid level is reduced, the sulfur foam generation and smooth overflowing are ensured, and the efficiency of desulfurization regeneration is improved.

Description

technical field [0001] The invention belongs to the field of chemical equipment, and in particular relates to an automatic flushing device for a sulfur bubble overflow weir of a regeneration tank. Background technique [0002] With the continuous improvement and improvement of the wet desulfurization process in recent years, the wet desulfurization process has been applied more and more in the fields of coal chemical industry, nitrogen fertilizer and other chemical industries. Regeneration of desulfurization liquid is the key and core link of desulfurization, sulfur analysis, regeneration, flotation and separation in wet system. Due to the characteristics of high viscosity and easy adhesion of sulfur foam, during the regeneration process of desulfurization liquid, sulfur foam is very easy to deposit sulfur foam overflow weir in the regeneration tank, resulting in blockage of sulfur foam overflow weir, resulting in the formation of sulfur foam cannot removed from the system....

AI Technical Summary

Problems solved by technology

Due to the characteristics of high viscosity and easy adhesion of sulfur foam, during the regeneration process of desulfurization liquid, sulfur foam is very easy to deposit sulfur foam overflow weir in the regeneration tank, resulting in blockage of sulfur foam overflow weir, resulting in the formation of sulfur foam cannot removed from the system

Aiming at the blockage of sulfur foam overflow weir, most manufacturers adopt the method of manual removal, which requires a large number of personnel operations and poor operating environment. At the same time, due to the poor timeliness of personnel operations, it also has a certain impact on the normal operation of the desulfurization system.
