Description

Technical Field

[0001] The utility model relates to the technical field of chemical industry, in particular to a sulfur trioxide vaporization anti-corrosion device. Background Art

[0002] Sulfur trioxide is a non-polar molecule. Its gaseous form is a serious pollutant and one of the main sources of acid rain. It is a colorless, transparent, oily liquid or solid (depending on the specific crystal form) at room temperature. It is solid under standard conditions and has a strong irritating odor.

[0003] However, in the prior art, most sulfur trioxide vaporization devices have relatively low corrosion resistance. The interior of the device is easily adhered to by vaporized sulfur trioxide. If it is not cleaned for a long time, it is easy to cause the inner wall to be corroded, thereby causing damage. When the vaporization operation is performed again, the purity of sulfur trioxide is also likely to be reduced, which ultimately affects the quality of electronic-grade sulfuric acid. Moreover, sulfur trioxide will produce harmful gases during the vaporization operation. Direct discharge without purification will pollute the environment, thereby affecting the surrounding environment. Utility Model Content
