Anti-corrosion liner construction method of wet flue gas desulfurization dust removing equipment

Abstract

The invention discloses an anti-corrosion liner of wet flue gas desulfurization dust removing equipment and a construction method and belongs to environmental-friendly equipment, in particular to the wet flue gas desulfurization dust removing equipment with an inner surface anti-corrosion layer. The anti-corrosion liner of the wet flue gas desulfurization dust removing equipment is characterized by comprising a framework material, a laying cushion layer, a sticking layer and a surface anti-corrosion layer, wherein the framework material consists of an inverted V-shaped spud pile with one end welded on an equipment shell and a steel wire mesh fixed by the inverted V-shaped spud pile; the laying cushion layer is an acid-proof cement layer which is adhered to the equipment shell and is applied outside the framework material; the sticking layer is a water glass and acid-proof cement mixed layer; and the surface anti-corrosion layer is formed by acid-proof ceramic tiles adhered onto the sticking layer. A structure that the acid-proof ceramic tiles are adhered onto the laying cushion layer by acid-proof cement is adopted. The anti-corrosion liner of the wet flue gas desulfurization dust removing equipment has the advantages of low cost, high temperature resistance, wear resistance, corrosion resistance, low anti-corrosion cost, difficulty in falling and easiness for repairing. The application for nearly ten years proves that the anti-corrosion liner has a good effect and a long service life which is over ten years.

Description

technical field [0001] The invention belongs to environmental protection equipment, in particular to wet flue gas desulfurization and dust removal equipment with an inner surface anticorrosion layer. Background technique [0002] The steel wet desulfurization dust collector has played a huge role in the desulfurization of flue gas from boilers and kilns, and has played a great role in the purification of coal-fired flue gas. However, in the wet desulfurization process, the SO2 in the flue gas mixes with the alkaline water in the desulfurization equipment to form acidic water, and the humidity is high, about 40°C, which greatly accelerates the corrosiveness of these acidic waters. Therefore, the anti-corrosion process of steel desulfurization and dust removal equipment is very important. Most of the current anti-corrosion measures are glass flake anti-corrosion methods, but its wear resistance is poor. It is not suitable for some occasions with dust wear or integrated desul...
