Electrochemical protection mainly solves the electrochemical corrosion of waste gas treatment equipment. Examples of electrochemical protection measures in chemical enterprises include: taking certain electrochemical protection measures on the surface of waste gas treatment equipment, isolating the equipment surface from the air, and cutting off the path of electrochemical corrosion. The principle of electrochemical protection is to sacrifice the anode to protect the cathode, while chemical waste gas treatment equipment is the cathode of electrochemical protection. In the corrosion prevention of chemical waste gas treatment equipment, electrochemical protection methods are actively promoted, which can be applied to various metal chemical waste gas treatment equipment to protect the use of the equipment.

 

Anti corrosion design refers to arranging anti-corrosion treatment according to the needs of chemical waste gas treatment equipment, comprehensively preventing equipment corrosion. Anti corrosion design is reflected in two aspects: structure and process. In the design process, chemical waste gas treatment equipment should follow the principle of simple structure, simplify the external structure of the equipment, and the external structure should not be concave to avoid increasing the probability of corrosion. For special chemical waste gas treatment equipment, it is necessary to design drainage holes to eliminate trapped water on the surface and inside, and ensure the dryness of the equipment. The materials of chemical waste gas treatment equipment and components should be consistent, and there should be no large gaps in the connection positions. Attention should be paid to the refinement of welding. According to the design of chemical waste gas treatment equipment, arrange the painting work at the weld seam, consider the performance of the chemical waste gas treatment equipment, provide a reasonable structural design, fully play the anti-corrosion effect of weld seam painting, ensure the accuracy of weld seam connection, and protect the use of the entire chemical waste gas treatment equipment.

 

The paint corrosion of chemical waste gas treatment equipment is a simple and effective measure to ensure the anti-corrosion characteristics of chemical waste gas treatment equipment in the external environment. For example, the anti-corrosion painting method for chemical waste gas treatment equipment creates isolation conditions between the environment and metals, preventing air oxidation and water erosion. Painting anti-corrosion has strong practicality. It is necessary to fully understand the performance, materials used, and usage of chemical waste gas treatment equipment according to its actual situation in order to scientifically paint anti-corrosion equipment and prohibit the risk of corrosion in chemical waste gas treatment equipment. In anti-corrosion painting, anti-corrosion paint should be used to adapt to the operating environment of chemical waste gas treatment equipment.
