Titanium Wet Chlorine Cooler for Chlor-Alkali Industry​

Specifications:

Titanium Wet Chlorine Cooler for Chlor-Alkali

Titanium tubular chlorine cooler adopts a vertical, floating head, steel shell rubber-lined head, and the pattern plate and pipe are pure industrial titanium. The diameter is 800 mm, 367 titanium tubes (26*1.5*4000mm), and the total heat transfer area is about 110 square meters. Wet chlorine gas goes into the tube, and cooling water goes out of the tube. The detailed structure is shown in Fig.

Application:

The application of titanium wet chlorine cooler and salt electrolysis to produce Chlor-alkali will generate a large amount of high-temperature wet chlorine gas, the temperature is generally 75-95 ℃, and it needs to be cooled and dried before it can be used. The production of chlorine gas produced by electrolysis of salt has previously affected the production and quality of chlorine gas due to unreasonable cooling processes or corrosion of cooling equipment, and also seriously polluted the environment. Titanium coolers resistant to high temperature and wet chlorine corrosion were put into production, which changed the production outlook of chlorine production in the Chlor-alkali industry. Titanium is extremely corrosion-resistant in the environment of high temperature and humid chlorine gas. The corrosion rate of titanium in chlorinated water at room temperature is only 0.000565mm/a; in chlorinated water at 80 °C, the corrosion rate of titanium is 0.00431mm/a; In % wet chlorine gas, the corrosion rate of titanium at room temperature is 0.00096mm/a. After many Chlor-alkali plants have used titanium wet chlorine gas coolers, some have been used for nearly 20 years, and they are still intact.

Features:

Titanium in Chlor- Alkali Industry

Because titanium has excellent corrosion resistance in wet chlorine gas, chloride, and chlorine-containing solutions, pitting corrosion and stress corrosion will not occur, which is unmatched by ordinary stainless steel. It is the reason why it is widely used as a corrosion-resistant material for equipment in many industrial sectors in contact with chemicals, and it solves the common corrosion problem that has existed in Chlor-alkali plants for many years. Therefore, the Chlor-alkali industry is one of the departments with the most applications for titanium equipment. The main titanium equipment includes wet chlorine coolers, metal anodes of electrolytic cells, heating pipes for dechlorination towers, pumps and valves for vacuum dechlorination of chlorine-containing brackish water, etc.
