50% lye primary heat exchanger belongs to the high-temperature section heat exchanger, which not only requires high temperature and high pressure resistance, the temperature is about 165 and the pressure is about 0.8MPa, but also needs to resist stress corrosion within a large temperature gradient range. The inner and outer tubes of 50% lye primary heat exchanger we produce are made of nickel, and adopt four-stage heat exchange technology, which can not only meet the requirements of high-temperature heat exchangers, but also ensure the safe and stable operation of the evaporation unit. The first stage of 50% lye primary heat exchanger is used to absorb heat in areas with large temperature gradients. It adopts a double-tube and double-shell heat exchanger. The wall thickness of the shell and tube heat exchange tube is 2.0mm, and the tube plate adopts strength welding; the second Stage 4 is used to absorb heat in areas with small temperature gradients. A single-flow heat exchanger is used. The wall thickness of 50% lye primary heat exchanger tube is 1.2mm. The manufacturing process of first expansion and then welding is still used. The mass fraction of the output from the evaporation unit is 48.5%, and the output temperature is 158°C. After passing through the heat exchanger, the temperature drops to about 115°C. Our mixed process shell and tube heat exchanger has been in operation for more than 5 years, and there has been no liquid leakage during the period;
The specification of the 50% lye primary heat exchanger you described includes the following:
The 50% lye primary heat exchanger is an important component in the solid caustic soda evaporation industry. It is used to transfer heat from one fluid to another in order to increase the concentration of the caustic soda solution. The heat exchanger is typically designed to operate under high temperature and high pressure conditions, and is made of materials that can withstand the corrosive effects of the caustic soda solution.
In the case of the 50% lye primary heat exchanger we mentioned earlier, the inner and outer tubes are made of nickel, which is a good choice of material for its high resistance to corrosion and high-temperature performance. The heat exchanger uses a four-stage heat exchange technology, which allows for efficient heat transfer across areas with both large and small temperature gradients.
The first stage of the heat exchanger is designed to absorb heat in areas with large temperature gradients. It uses a double-tube and double-shell heat exchanger with a 2.0mm wall thickness, which provides sufficient strength to withstand the high pressure and temperature of the 50% lye solution. The second to fourth stages use a single-flow heat exchanger with a thinner 1.2mm wall thickness, which is appropriate for absorbing heat in areas with smaller temperature gradients.
Overall, the 50% lye primary heat exchanger is to be well-designed and well-suited for the requirements of the solid caustic soda evaporation industry. Its use of nickel and four-stage heat exchange technology allows for efficient heat transfer and resistance to stress corrosion.It’s practiced that our 50% lye primary heat exchanger you produce has been operating for more than 5 years without any liquid leakage. The use of nickel in both the inner and outer tubes of the heat exchanger is a good choice because it offers excellent corrosion resistance and can withstand high temperatures and pressure.
