Introduction to Stainless Steel pall Ring Packing: Metal pall Ring is an efficient packing widely used in chemical, environmental protection, refining and other fields. Its design and performance make it an important filling material in tower interiors. Below, we will provide a detailed explanation of the metal ball ring from the aspects of structural characteristics, application cases, and performance data.   The structural characteristics of stainless steel pall rings: Metal pall rings are a new type of filler designed and improved based on traditional Raschig rings. It adopts a double-layer wall structure, with multiple uniformly distributed windows on the ring wall. These windows not only increase the specific surface area of the packing, but also improve the mass transfer efficiency between gas and liquid. At the same time, the height to diameter ratio of the metal ball ring is usually controlled within a certain range. This design enables the packing to form a more uniform distribution inside the tower, reducing short circuits and wall flow phenomena in the airflow.   Application case of stainless steel pall rings: In the chemical industry, metal pall rings are widely used inside various towers, such as absorption towers, distillation towers, extraction towers, etc. Taking the distillation tower of a large refinery as an example, the tower originally used traditional Raschig rings as packing, but during operation, it was found that the purity of the product at the top of the tower could not meet the design requirements. Later, the factory decided to use metal ball rings to renovate the tower. After the renovation, the purity of the tower top product has been significantly improved, and the pressure drop inside the tower has also been significantly reduced, thereby improving the energy efficiency of the entire production process. In addition, metal ball rings also play an important role in the wastewater treatment process in the field of environmental protection. A certain sewage treatment plant used metal Bao'er rings as the packing material for the bioreactor when treating industrial wastewater containing high concentrations of organic matter. Due to its excellent mass transfer performance and large specific surface area, metal Bao'er rings provide a favorable environment for the growth and reproduction of microorganisms. After a period of operation, the wastewater treatment efficiency of the factory has been significantly improved, and the effluent quality has reached the national discharge standards.    

The specifications of ceramic corrugated structured packing are divided into 700Y, 450Y, 350Y, 250Y, 150Y, etc. Different specifications correspond to different product dimensions in terms of length, width, and height.   When consulting ceramic corrugated structured packing, customers generally want to know the specific surface area, bulk density, porosity, inclination angle, pressure drop, theoretical plate number, hydraulic diameter, liquid load, factors and other parameters of different types of products. The length, width, and height parameters, even for the same type of ceramic corrugated filler, have different sizes. The tower diameter varies under different operating conditions, and the required length, width, and height are also different.   The function of ceramic corrugated structured packing Due to the unique structure of ceramics, they have good hydrophilicity. The extremely thin liquid film and inclined and tortuous airflow channels can promote the flow of airflow without blocking it, making ceramic fillers compatible with metal fillers. However, their corrosion resistance and high temperature resistance cannot be compared with metal fillers. The surface structure has good wettability, which can accelerate the flow of liquids and minimize the amount of retained liquid in the filler. Thereby reducing the chances of overheating, polymerization, and coking.   The different inclinations can be divided into X-shaped and Y-shaped. X-shaped inclination angle of 300, Y-shaped inclination angle of 450. The X-type pressure drop is relatively small, while the Y-type mass transfer performance is good. To balance pressure drop and mass transfer performance, holes can be opened on the plate. Due to the lack of significant amplification effect of regular packing, its surface roughness is superior to the unique corrosion resistance of the material, and it is used in mass transfer processes such as distillation, stripping, absorption, and extraction in petrochemical industry. Have you learned about the length, width, and height specifications of ceramic corrugated regular packing through the above introduction

Why is CPVC Teller rosette ring used for environmentally friendly high-temperature exhaust gas treatment？ CPVC Teller rosette ring is a powerful assistant for environmentally friendly high-temperature waste gas treatment. In the field of environmental protection, waste gas treatment is a crucial task. Especially in the treatment of high-temperature exhaust gas, it poses severe challenges to technology and equipment. And CPVC Teller rosette ring has become a powerful assistant in the field of environmental protection and high-temperature waste gas treatment due to its advantages and excellent performance.   CPVC Teller rosette ring has high temperature resistance. In the treatment process of high-temperature exhaust gas, ordinary materials often cannot withstand the test of high temperature and are prone to deformation, aging and other problems. The flower wreath filling is made of special chlorinated polyvinyl chloride material, which can withstand high temperatures stably for a long time, ensuring the normal operation of exhaust gas treatment equipment in high temperature environments. This characteristic has made it widely used in industries with severe high-temperature exhaust emissions, such as chemical, metallurgical, and power industries.     Has good chemical stability. In the process of exhaust gas treatment, various chemical substances are often encountered, which may cause corrosion to the packing and affect its treatment effect. However, it has excellent tolerance to most chemicals, is not prone to chemical reactions, and can effectively ensure the long-term stable operation of exhaust gas treatment systems. It can effectively resist acid and alkali corrosion, providing reliable protection for exhaust gas treatment.

The installation and acceptance of internal components and packing materials for methanol separation tower, distillation tower, methanol removal tower, dehydration tower, and solvent removal tower have been successful.   It is difficult to imagine the construction on site. In order to ensure the construction period, we insisted on working under the continuous heavy rainstorm, and it took 45 days to install in succession. Finally, we completed the task with the joint efforts of the owner and the professional installation team of Fangxing. Thank you for the full support of the owner and the hard work of the team!
