Abstract

The invention discloses a coating of a device for desulfurization of the flue gas, denitrification, and dust abatement, which is a high performance industrial anti-corrosion coating applicable to harsh conditions like an acid gas environment, etc., and is characterized by excellent permeability for anti-corrosion medium, fine wear resistance, good cohesiveness between a lining and a substrate, and good temperature upheaval-resistance. The coating is applicable to the protection of a chimney inwall provided with a desulfurating device. An approach convenient and easy to be popularized is provided for issues like desulfurization of the flue gas, denitrification, dust abatement and anti-corrosion, etc. The technique has a good effect when being adopted on devices for desulfurization of the flue gas, denitrification, and dust abatement.

Description

Technical field: [0001] The invention provides a coating capable of anti-corrosion flue gas desulfurization, denitrification and dust removal, and also discloses its production method, which belongs to the technical field of heavy anti-corrosion on the surface of environmental protection devices. Background technique [0002] The steel equipment of the flue gas desulfurization device (FGD) is in a strong corrosive environment during operation, and will be corroded quickly if it is not protected against corrosion. In addition to generating SO when burning coal 2 In addition, a small amount of SO 3 , NO X , HCL, HF and other gases, since the flue gas contains water (4-12%), it can form H in an instant 2 SO 4 , HCL, HF and other strong corrosive acidic solutions. At the same time, the flue gas containing soot passes through the equipment and pipes at high speed, and contacts with the absorption liquid in the absorption tower of the desulfurization device, causing serious w...
