Application of plate heat exchanger in chlorine and caustic soda industries
In the early days, plate heat exchangers were only used in light industrial sectors such as high temperature milk sterilization, fruit juice processing, and beer brewing. With the improvement of manufacturing technology, corrosion-resistant plate materials and high-temperature and corrosion-resistant gasket materials have gradually appeared, and the plates have gradually become larger. Currently. Plate heat exchangers have been widely used in various chemical industries, food industries, metallurgical industries, petroleum industries, power stations, machinery, sewage treatment and so on. 1、循环氯盐水的冷却及加热 2、从盐水中脱出氯气的冷却及加热 3、氯饱和冷剂的冷却 4、来自反应器的循环溶液的冷却，以上板片材料均为钛材。 Application of plate heat exchangers in the chlorine gas and caustic soda industries: 1.

The importance of plate heat exchangers in the chemical industry
In the early days, plate heat exchangers were mostly used for milk sterilization or beer processing. It has been widely used in industry as a compact heat exchange equipment. Through the application of practice, people gradually have a deeper understanding of its superiority. With the expansion of application fields and the progress of weaving technology, plate heat exchangers have become very important heat exchange equipment. Heat exchangers are used in daily life for heating fins, condensers on steam turbine installations, and oil coolers on space rockets. It is also widely used in chemical, industrial, power and atomic energy industries. The advantages of plate heat exchangers: high heat transfer coefficient, large logarithmic average temperature difference, large NTU (turbidity), strong temperature and pressure resistance, small footprint, light weight, low dirt coefficient, easy cleaning, etc. Its function is for the purpose of heat exchange. The application in the chemical industry can be the exchange of a relative amount of heat in a relative time; it can also be used for the purpose of recovering heat for the use of waste heat; Some equipment is damaged due to the increase in pressure caused by the increase in textile temperature. Traditional heat exchangers have the disadvantages of large floor space, low heat exchange efficiency, large heat transfer temperature differences, and easy scaling. They are not suitable for large heat exchange situations and are not suitable for large-scale use in the chemical industry. . The plate heat exchanger has high heat transfer efficiency, small temperature difference, strong anti-fouling and anti-scaling ability, high heat transfer coefficient, and can adapt to places with high critical loads. It is more and more mature in technology, and it will be more applied in the chemical industry in the future. widely. In short, plate heat exchangers have a variety of applications in the chemical industry. At present, the status has taken a lot of significance, and development must be diversified.
