Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the field of heater, especially a compact, high-efficiency online titanium heater with a control system. BACKGROUND
[0002] In the photovoltaic, semiconductor and medical industries, pure water is widely used in various process steps as a crucial resource. However, the unique properties of pure water, i.e. its extremely low ion concentration, pose unique challenges to the heating process. When pure water is heated, due to the low ion concentration in the water, metal ions (such as iron ions) in the stainless steel heater are more likely to dissolve and penetrate into the pure water, resulting in water pollution, which is undoubtedly a serious problem for industries with extremely high water quality requirements.
[0003] The common heater designs on the market mainly include box-type heating and coil-type heating. These designs, although to some extent meet the heating needs, have relatively large heating parts, resulting in more heat loss and low heating efficiency. This not only increases energy consumption, but also may affect the stability and efficiency of the overall process.
[0004] In terms of control, existing heaters also have many shortcomings. Some heaters still use traditional circuit breakers, fuses, relays and temperature controllers in combination, which is simple but lacks flexibility and intelligence. While some other heaters are equipped with relatively complete control systems, but are often bulky and rely on PLC as the central control, which not only increases the cost, but also brings inconvenience to subsequent maintenance and maintenance.
[0005] In terms of safety protection, existing heaters also have shortcomings. Many heaters rely only on circuit breakers and fuses as protection measures, while temperature protection is often shared by process temperature sensors. This protection method may not provide sufficient safety protection under complex and variable working conditions. Especially in the field of pure water heating, due to the special water quality, the corrosion resistance and safety of the heater are required to be higher.
[0006] In addition, the current domestic mainstream metal heater is mainly stainless steel heater. Although stainless steel heater performs well in some aspects, but in the field of pure water heating, its corrosion resistance is relatively weak, and the problem of metal ion precipitation is more serious. In contrast, titanium heater has more advantages in corrosion resistance, but the cost is also relatively high.
[0007] Finally, in terms of the configuration of the control system, many heaters are either not equipped with a control system, requiring the user to provide their own, or are only equipped with a rudimentary control system that cannot meet the requirements of safety and anti-interference. This not only increases the user's use cost, but also may bring hidden dangers to the safety and stability of the overall process.
[0008] In summary, the existing metal heater has many shortcomings in the field of pure water heating, including low heating efficiency, inflexible control, imperfect safety protection, and poor corrosion resistance. Therefore, developing a high-efficiency, intelligent, and safe metal heater is of great significance to meet the demand for pure water heating in the photovoltaic, semiconductor, and medical industries.
