Description
Technical Field
The invention belongs to the technical field of chemical equipment, and particularly relates to a liquid chlorine vaporizer.
Background
The liquid chlorine vaporizer is the key equipment in the chlor-alkali industry and has the function of converting liquid chlorine into gas. The common types include a shell and tube vaporizer and a coil vaporizer. Most of the tube plate orifices adopt a welding or expansion joint process, and the orifice corrosion and stress crack are often caused by process defects and complex overflowing media, so that the leakage at the orifice is caused.
Three common types of corrosion in liquid chlorine vaporizers are: crevice corrosion, pitting corrosion, stress cracking corrosion.
Among the various corrosions, crevice corrosion is the most common. Crevice corrosion occurs in the form of cracks, which occur at sites where the oxygen supply is insufficient, causing damage to the passivation film. Crevice corrosion may occur in the same material or between different materials where at least 1 of the materials is metal.
Pitting corrosion is localized corrosion occurring on the metal passivation film. If the passivation film is not regenerated fast enough, the corrosion is accelerated, and the depth of the corrosion is increased. Such corrosion is typically prone to occur in aqueous solutions containing halides such as chlorides.
Stress corrosion cracking is corrosion in which cracks are generated in a metal material under the action of tensile stress and a specific corrosion medium. The occurrence of cracks is often unexpected and no significant change is observed in the corroded part, the conditions for stress corrosion cracking being: 1. the material is sensitive to the particular medium causing stress corrosion; 2. the presence of this particular medium in a corrosive environment; 3. the component surface is applied with tensile stress exceeding a critical value, including internal stress; 4. other corrosion such as pitting or crevice corrosion.
Aiming at the corrosion problem of the liquid chlorine vaporizer, the traditional solution method mostly adopts a method of disassembling a weld repair or blocking a pipeline, but the fundamental problem cannot be solved, the working efficiency of the vaporizer is reduced, and finally, huge funds are invested to scrap and replace new components.
