Tube and tube heat exchangers, with their sturdy structure, high heat transfer efficiency, high temperature and pressure resistance, and wide applicability to various media, are the core heat exchange equipment in the energy industry. They are widely used in multiple sub sectors such as thermal power, nuclear power, new energy, and oil and gas extraction and processing. The specific application sc
The reboiler at the bottom of the tower is a crucial supporting device for chemical separation equipment such as distillation towers and absorption towers. Essentially, it is a high-efficiency heat exchanger installed at the bottom of the tower (the reboiler at the bottom of the tower), whose core function is to provide continuous heat and gas phase reflux for material separation within the tower,
The outer coil stainless steel tower is a core non-standard pressure vessel equipment in the petroleum refining industry. It uses stainless steel as the main material of the tower body, and the outer wall of the tower is surrounded by a coil structure. It has the characteristics of corrosion resistance, high temperature and high pressure resistance, high heat transfer efficiency, and flexible oper
Let's analyze the evaporation efficiency of the falling film evaporator in detail. The conclusion is that the falling film evaporator has a high evaporation efficiency and is an efficient and energy-saving evaporator. We will explain its efficiency performance and core reasons in detail.
The tower kettle reboiler is the core heat exchange equipment that is installed at the bottom or side of the distillation tower. Its function is to heat and vaporize the liquid phase material in the tower kettle, and the generated gas phase flows back into the tower to provide upward steam for distillation separation. Its design and operation need to be adapted to the requirements of gas-liquid ba
Tube and tube heat exchanger is a core heat exchange equipment with stable structure, high heat transfer efficiency, and strong adaptability in the metallurgical industry. It is widely used in key processes such as smelting, refining, waste heat recovery, and cooling in metallurgical production. It can handle high temperature, high pressure, and corrosive media, meeting the harsh working condition
