Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of anti-corrosion materials, in particular to an anti-corrosion device used in an ammonium sulfate production area. Background Art
[0002] In the ammonium sulfate treatment process, the main components of the slurry are ammonium sulfate, ammonium sulfite, ammonium bisulfite, chloride ions, etc., and some miscellaneous acids also exist. They are generally of low concentration but complex composition. The pH value is generally between 3 and 7, and the temperature is about 40℃ to 50℃. When the device is running, the overflow and leakage of slurry and bubbles will seriously corrode floor floors, ceilings, walls, grooves, cofferdams and surrounding equipment.
[0003] The original anti-corrosion layer of the cofferdam, floor and trench in the existing ammonium sulfate device area is mostly acid-resistant tiles with epoxy mortar grouting or granite blocks with epoxy mortar grouting. Acid-resistant tiles and granite blocks have good anti-corrosion performance. Even if there is serious leakage in the floor, from the surface, most of the acid-resistant bricks or blocks are not damaged, but chemical media usually penetrate from the grouting of tiles or granite blocks, causing the anti-corrosion layer to fail, and the corrosive liquid directly enters the concrete substrate, which in turn causes corrosion, powdering, strength reduction, peeling and damage to the concrete in various areas; if things go on like this, it will cause the bottom layer of the substrate to form a "karst landform corrosion" type suspension, ground depression and collapse, leaving a large safety hazard; at the same time, due to the penetration of chemical media, it will also cause pollution of the soil and groundwater at the bottom.
[0004] Therefore, in view of the different operating environments and corrosion conditions in various areas of the ammonium sulfate unit, it is urgent to develop an anti-corrosion device with a wider range of chemical corrosion resistance, corrosion medium permeability resistance, wear resistance and erosion resistance, substrate adhesion, compression and impact resistance, and certain temperature resistance.
