AI Technical Summary

Technical Problem

In the flue gas desulfurization system, the anti-corrosion layer on the surface of the support column is damaged due to the erosion of high-speed rotating slurry atomized particles, which leads to corrosion and perforation, threatening the structural stability and safety of the system.

Method used

A multi-layer protective structure is adopted, including a silicon carbide anti-corrosion layer, resin putty and a semi-circular cast stone protective casing plus a dynamic air curtain and a knocking mechanism. High-pressure air is used to form a surrounding air curtain layer and periodic knocking to remove attachments, forming a multi-level protective barrier.

Benefits of technology

Effectively prevent slurry from directly contacting the pillar surface, extend the pillar life, prevent corrosion, and ensure the stability and safety of the system structure.

Abstract

The invention discloses an anti-corrosion and anti-scouring structure widely applicable to a support column of a desulfurization system, and relates to the technical field of flue gas desulfurization. The air inlet mechanism is arranged on the inner wall of the supporting column, and the air inlet mechanism is used for being connected with an air compressor to input external high-pressure air; and the protection mechanism is arranged on the air inlet mechanism, and the protection mechanism comprises a communicating pipe. According to the anti-corrosion and anti-scouring structure widely suitable for the desulfurization system supporting column, an external air compressor is connected to the upper connecting pipe, the compressor is started, air is continuously supplied to the air inlet mechanism, and compressed air sequentially flows through the middle connecting sleeve and the lower connecting pipe and then enters the communicating pipe through the upper connecting pipe and the lower connecting pipe; compressed gas is input into the hollow stainless steel pipe hoop through the communicating pipe to form a closed gas cavity, high-pressure gas flow is sprayed towards the surface of the supporting column through the gas spraying openings in the long and thin pipes, a surrounding type dynamic gas curtain layer is formed outside the gas spraying openings, and slurry and corrosive gas are prevented from making direct contact with the surface of the supporting column.
