Heat exchange station equipment refers to the room connected to the primary and secondary networks and equipped with relevant equipment, instruments and control equipment for user connections.It is the hub for heat exchange, heat distribution, and system monitoring.
The core equipment of the heat exchange station mainly includes the following types:
Plate heat exchanger: This is a widely used heat exchange device made of stacked corrugated metal sheets.It is compact, lightweight, and easy to disassemble and clean.Heat exchangers mainly exchange heat through three methods: conduction, convection and radiation. They are suitable for many industries such as chemical industry, metallurgy, electric power, food, papermaking, etc.
Shell and tube heat exchanger:This type of heat exchanger relies on the relative movement between the tube wall and the shell to exchange heat.It is mainly composed of shell, tube bundle and tube sheet, etc. It has a simple structure, is easy to disassemble and clean, and is suitable for a variety of media and working conditions.According to different structural forms, shell and tube heat exchangers are divided into two types: shell and tube type and sleeve type.
Cooling tower: There are two main ways for cooling towers to dissipate heat:One is direct evaporation to absorb heat, and the other is to absorb heat through contact between water and air and discharge it into the atmosphere.Cooling towers are often used to dissipate excess heat from heat exchangers to the atmosphere.
Condensate and condensate extraction pump:These devices are used to recycle condensed water in steam, collectively known as steam traps and steam pipes.Their working principle is to use mechanical action to force condensed water into liquid water and discharge it into the sewer.
Fan:The function of the fan is to draw in air and transport the gas through the centrifugal force generated by high-speed rotation to achieve ventilation.
Storage tank: A storage tank is a closed container for storing liquid or solid substances.
Auxiliary and control equipment: ensuring stable operation of the system
This type of equipment is responsible for monitoring, regulating and protecting the entire heat exchange system to ensure its safe and efficient operation.
including PLC control cabinet (for automatic control), temperature sensors, pressure sensors, flow sensors, real-time monitoring and adjustment of system parameters.
including stop valves (to cut off the medium), regulating valves (to adjust flow/temperature), safety valves (to prevent system overpressure), and check valves (to prevent backflow of the medium).
water softening equipment (removes calcium and magnesium ions in water to prevent scaling), decontamination device (filters impurities in the medium to protect the heat exchanger and water pump), pressure gauge/thermometer (intuitively displays system pressure and temperature).
Circulation and conveying equipment: promote the flow of medium.
This type of equipment provides power for the circulation of hot and cold media, ensuring that heat can be transferred in the pipe network.
divided into primary network circulation pump and secondary network circulation pump, which respectively promote high-temperature water and low-temperature water to circulate in their respective pipe networks.
When the pressure of the secondary network drops due to leakage or other reasons, the make-up water pump adds softened water to the system to maintain stable system pressure.
discharges sewage and impurities in the system or empties accumulated water in the equipment during maintenance.
Well, the above is the type of heat exchange station equipment analyzed by the editor. I hope it will be helpful to everyone.
