Many people want to know about the sorting and working principles of heat exchangers. Heat exchangers include condensers, coolers, heaters, evaporators, reboilers, etc. When it comes to the sorting of heat exchangers, we can divide them into regenerative type, partition type and mixed type.
What are the functions of regenerative heat exchangers? The heat exchanger has valve switching and rotary functions. The principle of this heat exchange is to heat the solid material to a certain temperature. This is through a heat storage body composed of solid groups. Then it can heat the solid material to a certain temperature. This is through a heat medium. Heating a cold solid can transfer heat from a high-temperature fluid to a low-temperature fluid. It achieves the purpose and function of heating.
There are many categories of partition heat exchangers: spray heat exchanger, jacket heat exchanger, shell-and-tube heat exchanger, plate heat exchanger and immersion snake tube heat exchanger.
Plate heat exchanger is a classic partition heat exchanger. Plate and sealant gasket are its main structures. This kind of heat exchanger occupies a dominant position in the industrial field. It has advantages that cannot be underestimated. Many industries have replaced shell-and-tube heat exchangers with it.
Shell-and-tube heat exchangers are named after the principle of heat exchangers. Under normal circumstances, shell-and-tube heat exchangers have two forms of heat exchange fluids. The flow outside the tube is called the shell side. The flow in the pipe is the pipe pass. The main structure consists of: tube plate, shell, tube bundle, head and other parts. Its shell is round. The interior is equipped with spiral tubes or parallel tube bundles. Two sections of the tube bundle are fixed on the tube sheet.
Hybrid heat exchangers have a wide range of applications. The use requirement of this kind of heat exchanger is that hybrid heat exchangers can be used as long as fluids are allowed to mix with each other. According to the purpose, it is divided into the following types.
Hybrid condenser. The commonly used method is steam condensation. It is the direct contact between steam and water.
Cooling tower (cold water tower). This heat exchanger is energy-saving to use. It can cool the water that has warmed up in production through mechanical ventilation or natural wind. The economic benefits of the system are improved.
What is the main working principle of jet heat exchanger? This is a heat exchanger that can be ejected through a nozzle with higher pressure. The speed is fast. The low-pressure fluid flow channel can be mixed into direct contact with the jet and then enter the diffusion tube together. After reaching the same temperature as the outlet of the diffuser, it can be provided to users for use.
The washing tower (gas washing tower) is to wash gas. This is used in the industrial field. The liquid is used to absorb some components in the gas mixture to remove dust from the gas. The common use is cooling gas.
