Technical Field

[0001] The invention relates to the technical field of plate heat exchangers, in particular to a plate heat exchanger for chemical production. Background Art

[0002] Plate heat exchangers are a type of equipment that is widely used in chemical production due to its excellent heat exchange efficiency. Its core structure consists of multiple thin metal plates that are precisely arranged to form fluid channels, allowing fluid to flow between the plates, thereby achieving effective heat transfer. This design is particularly suitable for heat exchange between liquids and liquids, and between liquids and gases, and can quickly increase or decrease the temperature of the fluid in a short period of time. Compared with traditional tube heat exchangers, plate heat exchangers have significant advantages. It has a small footprint and is suitable for use in industrial environments with limited space; due to its large heat transfer area, it can provide higher heat exchange efficiency under the same volume, thereby improving overall production efficiency. The modular design of the plate heat exchanger makes it easy to disassemble and clean, reducing maintenance costs and extending the service life of the equipment. In modern chemical processes, plate heat exchangers can not only effectively improve the utilization rate of thermal energy, but also adapt to a variety of process requirements, and are an important tool for improving production efficiency. Due to its good adaptability and high efficiency, plate heat exchangers have become indispensable equipment in many industries such as chemical, pharmaceutical, and food processing.

[0003] Although plate heat exchangers have many advantages, they still have some disadvantages. During long-term use, certain chemical media can cause corrosion or scaling of the equipment, thereby reducing the heat exchange effect. Uneven distribution of fluid between the plates may cause local overheating or cooling, affecting the overall operating efficiency. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides a plate heat exchanger for chemical production, which solves the problem that corrosion or scaling reduces the heat exchange effect, and the problem that uneven distribution of fluid between plates causes local overheating or cooling.

The material of the magnetic sheets is iron, and a flow hole is arranged on the upper surface of the first heat exchange plate.

[0006] Preferably, the outer surface of the support frame rod is provided with a threaded opening, the first side plate and the second side plate are respectively located on both sides of the second heat exchange plate and the first heat exchange plate, and the outer surface of the threaded opening is provided with a bolt, and the lower side of the bolt is in contact with the second side plate.

[0013] The present invention provides a plate heat exchanger for chemical production, which has the following beneficial effects: The plate heat exchanger for chemical production has a trapezoidal heat exchange plate design that can enhance the turbulence effect when the liquid flows. Turbulence not only helps to improve the heat exchange effect, but also reduces the possibility of scaling, thereby extending the service life of the equipment. By increasing the complexity of the fluid's movement, heat transfer can be carried out more effectively. The application of magnetic sheets enables the separator to flexibly adjust its angle under the influence of the external magnetic field. This adjustment helps to optimize the flow speed and direction of the fluid, further improving the heat exchange effect. By changing the flow pattern, the magnetic sheet can also effectively reduce the formation of scale and ensure the long-term and efficient operation of the heat exchanger. The design of the air blowing device introduces bubbles into the flow cavity formed by the trapezoidal heat exchanger plate, which enhances the mixing of the fluid. This not only helps to remove scale attached to the heat exchanger plate, but also further improves the overall efficiency of the heat exchanger. This comprehensive design scheme not only improves the working efficiency of the heat exchanger, but also reduces the maintenance frequency and cost, providing a more reliable and economical solution for chemical production.
