With the development of industry, flue gas emissions have increasingly become a major source of environmental pollution. In order to reduce the emission of harmful gases and reduce the impact on the environment, catalytic incineration flue gas treatment technology has been widely used. However, in the catalytic incineration process, the waste heat generated by the combustion of flue gas is often used.
Wasted. In order to improve energy efficiency, measures need to be taken** to use these waste heats. Corrosion resistance is a crucial factor when performing waste heat**.
The core of catalytic incineration flue gas treatment technology is the use of catalysts to convert harmful gases into harmless substances. Under the action of a catalyst, the oxidation reaction of organic waste gas in the flue gas at high temperature generates a large amount of heat. If these heat are not used in time, it will not only lead to waste of energy, but also increase thermal pollution to the environment. Therefore, it is very necessary to catalyze the waste heat of incineration flue gas.
However, due to the exposure and reaction of various chemicals in the flue gas treatment process, the flue gas waste heat** equipment faces serious corrosion problems. On the one hand, oxides and acids in the flue gas will corrode the surface of the equipment, shorten the life of the equipment, and affect the safety of the equipment.
Run. On the other hand, particulate matter and heavy metal substances in the flue gas will form a corrosive atmosphere at high temperatures, accelerating the corrosion rate of the equipment. Therefore, the corrosion resistance of the material should be considered when designing and selecting catalytic incineration flue gas waste heat equipment.
At present, there are many corrosion-resistant materials that can be applied to catalytic incineration flue gas waste heat equipment. Common corrosion-resistant materials are stainless steel, nickel-based alloys, ceramic materials, etc. These materials have good chemical stability and high temperature resistance, and can operate stably for a long time in complex flue gas environments. In addition, different materials can be selected for compounding according to the actual situation to improve the corrosion resistance of the equipment.
In addition to the selection of corrosion-resistant materials, other measures can be taken to improve the corrosion resistance of the equipment. First of all, the equipment is fully anti-corrosion treatment, such as plating, coating, etc., to form a protective film to reduce direct contact with corrosive media. Secondly, strengthen the cleaning and maintenance of the equipment, remove the sediment in the flue gas in time, and reduce the accumulation of corrosive media. Finally, when designing the equipment structure, the fluid channel should be reasonably arranged to reduce the dead angle and dust accumulation, and reduce the erosion of the corrosive medium to the equipment.
In summary, catalytic incineration of flue gas waste heat** is an important means to improve energy efficiency. However, corrosion resistance is a key issue when performing waste heat**. The correct selection of corrosion-resistant materials and appropriate anti-corrosion measures can improve the corrosion resistance of the equipment, prolong the service life of the equipment, and ensure the safe operation of the equipment. At the same time, it is also necessary to carry out long-term monitoring and maintenance work to detect and solve potential corrosion problems in a timely manner, ensure the normal operation of the catalytic incineration flue gas treatment system, and contribute to environmental protection and energy conservation.
