Abstract

The invention discloses an anticorrosive material for a smoke discharge and desulfurizing chimney, which comprises an anti-permeability material and an abrasion-resistant material, wherein the anti-permeability material mainly comprises EpigenXD modified epoxy resin added with glass flakes, and the abrasion-resistant material mainly comprises the EpigenXD modified epoxy resin added with abrasion-resistant white corundum filler particles. The abrasion-resistant white corundum filler particles are divided into fillers I and fillers II, and the fillers I and the fillers II are mixed according to a certain proportion. The anticorrosive material for the smoke discharge and desulfurizing chimney is small in construction difficulty, low in cost, good in anticorrosive effect, good in abrasion-resistant performance, capable of effectively preventing damage of external force and internal stress and resisting to corrosion of acid liquor or scour of smoke and convenient in use and maintenance. In addition, scour and abrasion damage which easily happen to the anticorrosive material of the smoke discharge and desulfurizing chimney are effectively avoided, service life of an anticorrosive layer is prolonged, and maintenance cost can be reduced to a large extent.

Description

technical field [0001] The invention relates to the field of industrial anticorrosion materials, in particular to an anticorrosion material used for exhaust gas desulfurization chimneys. Background technique [0002] With the implementation of the national energy-saving and emission reduction strategic goals, thermal power plants or heating boilers need to carry out flue gas desulfurization and purification. After desulfurization, the corrosiveness of the internal environment of the chimney increases. Domestic chimneys that have been anti-corrosion after desulfurization have an anti-corrosion effect. It is not ideal, and the main problems are: cracking, leakage, peeling, etc. Most of the parts appear in seams, dust accumulation platforms, corbels, high-speed airflow areas, etc. [0003] In the desulfurization system, the flue gas treatment system (absorption tower, etc.), the flue gas transmission and discharge system (flue), and the chimney must all be treated with anticorr...
