Anticorrosion treatment of regenerative thermal incinerator The regenerative thermal incinerator is often used for organic waste gas purification treatment, also known as RTO equipment. Three chamber RTO furnace and rotary RTO furnace are commonly used. The waste gas enters the heat storage chamber through the air duct, is heated by the ceramic heat storage body, and then enters the combustion chamber for thermal oxidation at about 760 ℃. The purified gas is discharged through the tail flue and chimney or reaches the next treatment process. During operation, due to the complex composition of waste gas, sulfur S, chlorine Cl, etc. are also common corrosive impurities in addition to organic substances

Antiseptic coating for ZS-1033 quartz sand pickling tank Pickling corrosion in the quartz sand pickling industry is a common problem in the industry. Quartz sand pickling tank plays an important role in quartz sand processing. However, the acid substances produced in the acid cleaning process of quartz sand will corrode the surface of the acid cleaning tank and affect its service life. Therefore, it is of great significance to carry out anti-corrosion treatment on quartz sand pickling tank. This article will introduce the anti-corrosion methods, process flow and factors affecting the anti-corrosion effect of pickling tanks, with a view to providing reference for related industries. Anticorrosion methods of pickling tank: common anti-corrosion methods of pickling tank include coating

***Ammonium hydrogen: It is a corrosion product with the chemical formula of NH4HSO4, colorless crystal, easily soluble in water, almost insoluble in ethanol, acetone and pyridine, and its aqueous solution is strongly acidic. Store in a cool, dry and ventilated warehouse to prevent containers from being damaged and dissolved by moisture*** Ammonium hydrogen is mainly produced in the process of SCR ammonia denitrification. The active component V2O5 in the catalyst can accelerate the conversion of SO2 in the gas phase to SO3, and then react with the escaping NH3 in the reducing agent to generate * * * ammonium hydrogen. Features: melting point temperature is 147 ℃, boiling point temperature is 350 ℃, easy to form liquid * *

In the north of China, the cold and dry winter determines the key role of heating boilers in residential heating and industrial heating. This is a heating season that lasts for several months. When the heating boiler operates in * * *, it will encounter two completely different corrosion problems. First of all, under the high temperature operation state, the central temperature of the furnace of the heating boiler is very high, but the furnace wall temperature is relatively low, generally 300~400 ℃. This extreme high temperature environment will cause high-temperature oxidation corrosion, deposition corrosion caused by various corrosive substances brought in by fuel, such as sulfide, chloride, and high-temperature liquid corrosion. Therefore, for

Working mechanism of chlorine resistant coating Zhisheng Metalworking//136 * -//612//8 * - 735//* 9ZS-711 inorganic anti-corrosion coating can play a good role in protecting metal from chloride ion corrosion. The following will start with the principle of chloride ion corrosion of metals, and introduce how the anti-corrosion coating plays a protective role. Chlorine ion is a highly corrosive ion, which exists in many chemical production scenarios. When a metal is exposed to an environment containing chloride ions, chloride ions will penetrate the metal oxide layer to reach the metal surface, and electrochemical reaction will occur with the metal to form soluble metal salts. This electricity
