one）Product Description:

Produced by the companyceramicsRaschig ringIt is one of the earliest artificial fillers used in industry. It is usually made of ceramics, with a height equal to the diameter, and commonly used sizes ranging from 25mm to 75mm (there are also sizes as small as 6mm and as large as 150mm). The ceramic wall thickness ranges from 2.5mm to 9.5mm, and if strength permits, the wall of the ring should be thinned as much as possible. Although the mass transfer performance of Rasi ring is not ideal, it is still adopted by some factories due to its simple structure, easy manufacturing, and low price.

　　As the gas velocity increases, the frictional force between the two-phase fluids also increases. When the gas velocity increases to a certain value, the flow of the liquid begins to be hindered by the frictional force between the two-phase fluids, causing the liquid holding capacity of the packing layer to increase with the increase of gas velocity. This phenomenon is called liquid blocking phenomenon.

　　Produced by the companyceramicsRaschig ringIt is the earliest annular packing with a fixed geometric shape in the history of tower packing. The characteristics of Rascal ring are that the outer diameter and height of the packing ring are equal, the structure is simple, and the price is low. However, there are phenomena such as uneven liquid distribution and severe wall flow channel flow.

two）Product Principle:

　　Produced by the companyceramicsRaschig ringThe inflection point is called the load point, and the empty tower gas velocity corresponding to the load point is called the load point gas velocity. After exceeding the gas velocity at the loading point, the slope of the p/H-u relationship line increases, which is beneficial for improving the mass transfer rate. If the gas velocity continues to increase to the next turning point, the increasing liquid holding capacity in the packing layer will fill the free space of the entire packing layer with liquid, resulting in a sharp increase in pressure drop. At this point, the liquid begins to transition from a dispersed phase to a continuous phase, and the gas begins to transition from a continuous phase to a dispersed phase. The Raschig ring bubbles through the liquid layer and carries a large amount of liquid out of the top of the tower. The operation of the tower is extremely unstable and even completely destroyed, a phenomenon known as flooding. The turning point at which liquid flooding occurs is called the flooding point, and the corresponding empty tower gas velocity is called the liquid flooding gas velocity or flooding point gas velocity. The factors that affect the gas velocity of the pan point mainly include the characteristics of the filler (specific surface area, porosity, geometric shape, etc.), the physical properties of the fluid (density, viscosity, etc.), and the flow rate of the gas-liquid two-phase flow. The pan point gas velocity is the upper limit of the normal operating gas velocity of the packed tower, and the actual operating gas velocity is usually taken as 50% to 85% of the pan point gas velocity. Ceramic Ball Ring Packing is a type of annular packing with equal height and diameter developed on the basis of ceramic Rascal Ring, which allows gas and liquid in the packing tower to freely pass through the window holes, improves gas-liquid distribution, and fully utilizes the inner surface of the ring. Ceramic ball rings have excellent acid and heat resistance, and can withstand corrosion from various organic acids and solvents, making them suitable for use in various high-temperature environments.
