Air separation equipment adopts various technologies and methods in filtering, pre cooling, and purifying air to ensure the purity and quality of the final product.
Air filtration is the first step in the pretreatment of air separation equipment, with the main purpose of removing particulate matter and impurities from the air that may cause wear, corrosion, or affect separation efficiency. Using raw air filters, dust particles in the air are effectively removed through mechanisms such as inertial impact, Brownian diffusion, and direct blocking. The main function of the pre cooling system is to improve the efficiency of air separation and protect the core components of the air separation equipment. Before the air enters the separation tower, its temperature is lowered through a pre cooling system to reduce the moisture and carbon dioxide content in the air, thereby avoiding these components from condensing into ice or solids at low temperatures and affecting the separation process. Use a heat exchanger to exchange heat between air and a cold source (such as cold water or cold air), reducing the temperature of the air. Air purification is a key step in the pretreatment of air separation equipment, with the main purpose of removing harmful gases and impurities such as moisture, carbon dioxide, hydrocarbons, etc. from the air. These impurities may cause corrosion, blockage, or affect the purity of the product on the equipment. Purification methods: drying, adsorption, low-temperature condensation.
Air separation equipment preprocesses the air through three steps: filtration, pre cooling, and purification to ensure the purity and quality of the final product.

Shell and tube air separation heat exchanger is the most representative wall heat exchanger. It has a long history of application and is still dominant in all heat exchangers. Shell and tube heat exchanger is mainly composed of shell, tube bundle, tube sheet and head. Most of the shell is round, and there are parallel tube bundles inside. Both ends of the tube bundle are fixed on the tube plate. In shell and tube heat exchanger, there are two kinds of fluids for heat exchange. One kind of fluid flows in the tube, and its stroke is called tube side. The other flows outside the tube and its stroke is called shell side. The wall of tube bundle is the heat transfer surface. In order to improve the heat transfer coefficient of the fluid outside the tube, a certain number of transverse baffles are usually installed in the shell. The baffle can not only prevent the short circuit of the fluid and increase the velocity of the fluid, but also force the fluid to flow through the tube bundle man
