When it comes to liquid-liquid extraction procedures or liquid-liquid contacting activities, jet flow ring packing is the most common use. The following is a list of particular applications within which Super duplex stainless steel pall ring packing is often utilized: 1. Solute Extraction: Super duplex stainless steel pall ring packing is a technique that is often used in solvent extraction procedures. This technique is used to promote the transfer of solutes between two liquid phases that are incompatible with one another. It does this by improving the mixing and interaction between the feed solution and the solvent, which in turn makes it possible to extract the components that are sought more effectively. 2. Reactive Extraction: Reactive extraction is a process that includes the simultaneous extraction of two liquid phases and reactivity of chemical substances between them. Jet flow ring packing encourages intensive mixing and contact, which improves the kinetics of the reaction and makes it easier to recover the products of the process. 3. Extraction of Liquids from Liquids: Jet flow ring packing is employed in typical liquid-liquid extraction operations.

This is referred to as “liquid-liquid contact.” Jet flow ring packing makes it easier for liquids to come into contact with one another by generating a significant amount of turbulence and increasing the amount of interfacial area created between the two phases.                                     Chemical Reactors: Jet flow ring packing may be used in chemical reactors for liquid-liquid reactions that need improved mixing and contact. This is the case when both of these conditions are met. It does this by facilitating effective mass transfer and reaction kinetics, which ultimately results in enhanced conversion and selectivity. It is dependent on the needs of the process, such as the intended mass transfer efficiency, phase separation characteristics, chemical compatibility, and operating circumstances, that the precise selection of Jet flow ring packing is made. In order to maximize the performance of the process and obtain the required separation or reaction output, the design of the jet flow rings, including their size, shape, and configuration, may be customized. Super duplex stainless steel pall ring packing made of super duplex stainless steel packaging The qualities of low pressure drop, big flux, and high efficiency are actually possessed by super duplex stainless steel pall ring packing, which is constructed of either material classified as 2507 or material classified as 2205. Additionally, metal pall ring is also included in this category. When compared to PALL rings of comparable diameters, HYPAK packing demonstrates a comparatively smaller pressure drop and a much greater mass transfer efficiency. This indicates that when HYPAK packing is used, the fluid encounters less resistance as it flows through the packing, which ultimately results in a reduction in the amount of pressure loss that occurs inside the system. Additionally, the packing layer’s ability to distribute liquids effectively inside the layer adds to an increased mass transfer efficiency, which in turn makes the packing layer more successful in chemical and adsorption processes.size in millimeters surface area in square meters per cubic meter vacancy fraction in percent number per cubic meter Additionally, the existence of window holes on the wall of the Super duplex stainless steel pall ring packing makes it easier to distribute gas and liquid in a consistent manner throughout the packing layer, which ultimately results in an improvement in the performance of mass transfer. Through the use of this structural design, the surface area and contact area of the packing are increased, which in turn facilitates the effective transfer of mass between the gas and liquid phases. Consequently, the advantages of low pressure drop, big flux, and high efficiency are offered by both the metal pall ring and the super duplex stainless steel pall ring packing, which may be made of either 2507 or 2205 material. Given these qualities, they are suited for a wide range of applications in the chemical and adsorption fields. A 50/50 dual phase structure is commonly produced by the 2507 and 2205 metal pall rings after they have been subjected to the necessary solid solution treatment. This results in the rings exhibiting a perfect aV ratio. With a rise in temperature, the ferrite phase of the steel becomes more prevalent at temperatures higher than 1050 degrees Celsius. The substantial nitrogen component of these steels, on the other hand, prohibits considerable changes in the phase ratio before temperatures below 1300 degrees Celsius. These steels have the potential to develop V2 phase, intermetallic phases (such as 6 phase, X phase, R phase, and C phase), and oxide precipitates like Cr2N on their ferrite matrix if they are not subjected to age treatment at varying temperatures or heat treatment. Generally speaking, carbides are not found in these steels because of the low carbon content that they have, which is normally between 0.01% and 0.02%. In a nutshell, the microstructure of the 2507 and 2205 metal pall rings reveals a 50/50 dual phase structure when they are treated to an appropriate treatment with a solid solution. Over a specific temperature range, the phase ratio maintains a level of stability that is reasonably consistent. The lack of an aging treatment, on the other hand, may result in the formation of V2 phase, intermetallic phases, and oxide precipitates on the ferrite matrix. Carbide precipitates, on the other hand, are normally rare because of the low carbon content.

Iron, chromium, nickel, and a few other alloying elements like molybdenum and nitrogen make up the majority of their composition. 2507 material is superior than 2205 material in terms of corrosion resistance and corrosion resistance because it includes greater levels of chromium, molybdenum, and nitrogen than 2205 material does.One kind of filler is known as a super duplex stainless steel pall ring. This type of filler is often constructed out of metal elements like stainless steel. The filler has a shape that is comparable to a ring, and it has a number of vertical structures that are wavy or sheet-like. These structures are designed to enhance the filler’s surface area and improve its mass transfer ability.As a result, the super duplex stainless steel ball ring packing may be manufactured based on metal ball rings that are constructed of either 2507 or 2205 materials. Within the realm of demanding chemical and adsorption processes, this particular form of filler is used extensively for the purpose of providing effective mass transfer and resistance to corrosion.I am.

The wire mesh demister The wire mesh demister is composed of two parts: the steam liquid filter mesh pad (assembled by several mesh blocks) and the support. The mesh block is composed of several layers of Pingpu corrugated vapor-liquid filter screen, grid and distance rod.The wire mesh demister is a gas-liquid separation device. When the gas passes through the wire mesh pad of the demister, it can remove the entrained mist and other moisture substances. HG/T21618-1998 standard is a new standard revised on the basis of the original Ministry of Chemical Industry HG5-1404-81, HG5-1405-81 and HG5-1406-81, combined with the actual use experience of wire mesh demister and the advanced technology in the imported device. The materials selected for the screen demister are divided into two types, one is plastic and the other is metal. The plastics are subdivided into PP polypropylene, PE polyethylene, PVC polyvinyl and PTFE polytetrafluoroethylene. Metal is subdivided into 201, 304, 304L, 321, 316, 316L, 310S, NCU-30, Monel400, N201, and other materials. The wire mesh demister Wire mesh demister, which is mainly used for separating diameters greater than 3 μ m～5 μ When the gas with mist rises at a certain speed and passes through the wire mesh on the grid, the inertia of the rising mist makes the mist collide with the filament and adhere to the surface of the filament. The fog on the surface of the filament is further diffused and the gravity sedimentation of the fog itself makes the fog form large liquid droplets and flow along the filament to its interlacing place. Due to the wettability of the filaments, the surface tension of the liquid and the capillary action of the filaments, the droplets become larger and larger, until their gravity exceeds the combined force of the rising buoyancy of the gas and the surface tension of the liquid, they will be separated and fall, and flow to the downstream equipment of the container. As long as the operating gas speed and other conditions are properly selected, the demister efficiency can reach more than 97% after the gas passes through the wire mesh demister, which can completely remove the fog.

The working table is also provided with a feeding port, and the lower end of the feeding port is provided with a tongue mould for punching out the ball ring tongue body. The upper die is arranged side by side with the cutting edge and the bending die. The inlet is a"Mouth" shape. The die for the tongue page is a knife-shaped die which is fixedly connected to the base. The model of the tongue page is two rows, three in each row. The die is detachably connected to the punch. In working condition, the stainless steel plate extends into the Feed Inlet. The two upward-extending tongue pages are punched out of the tongue body model, and the slider is extended outward. Then use the cutter to cut the semi-finished product. At the same time, the bending die is cut into a"U" shape. After that, the slider is ejected inward and the semi-finished product labeled"U" is ejected into the molding die, which is rounded up to create a stainless steel ball ring. It changes the present situation that the traditional process needs three processes to produce"Ball ring", and further improves the production efficiency.

The wire mesh demister The wire mesh demister is composed of two parts: the steam liquid filter mesh pad (assembled by several mesh blocks) and the support. The mesh block is composed of several layers of Pingpu corrugated vapor-liquid filter screen, grid and distance rod.The wire mesh demister is a gas-liquid separation device. When the gas passes through the wire mesh pad of the demister, it can remove the entrained mist and other moisture substances. HG/T21618-1998 standard is a new standard revised on the basis of the original Ministry of Chemical Industry HG5-1404-81, HG5-1405-81 and HG5-1406-81, combined with the actual use experience of wire mesh demister and the advanced technology in the imported device. The materials selected for the screen demister are divided into two types, one is plastic and the other is metal. The plastics are subdivided into PP polypropylene, PE polyethylene, PVC polyvinyl and PTFE polytetrafluoroethylene. Metal is subdivided into 201, 304, 304L, 321, 316, 316L, 310S, NCU-30, Monel400, N201, and other materials. The wire mesh demister Wire mesh demister, which is mainly used for separating diameters greater than 3 μ m～5 μ When the gas with mist rises at a certain speed and passes through the wire mesh on the grid, the inertia of the rising mist makes the mist collide with the filament and adhere to the surface of the filament. The fog on the surface of the filament is further diffused and the gravity sedimentation of the fog itself makes the fog form large liquid droplets and flow along the filament to its interlacing place. Due to the wettability of the filaments, the surface tension of the liquid and the capillary action of the filaments, the droplets become larger and larger, until their gravity exceeds the combined force of the rising buoyancy of the gas and the surface tension of the liquid, they will be separated and fall, and flow to the downstream equipment of the container. As long as the operating gas speed and other conditions are properly selected, the demister efficiency can reach more than 97% after the gas passes through the wire mesh demister, which can completely remove the fog.

1. Reducing pressure drop: Metal stepped rings have large gaps and flux in the path of gas-liquid flow, which can reduce pressure drop. 2. Increasing the capacity of the reaction tower: The increase in the capacity of the reaction tower is the direct reason for the decrease in pressure drop. The metal step ring keeps the reaction contact away from the pressure drop contact with overflow phenomenon, which means it can handle more gas-liquid and increase the capacity of the reaction tower. 3. Enhanced anti fouling ability: The pointing position of the metal step ring enables the gap in the direction of gas-liquid flow to reach a value, so any solid masonry can pass through the packing layer with the gas-liquid flow. 4. Improving reaction efficiency: The metal step ring limits its ring surface to be vertical rather than parallel, and this design has more prominent advantages in mass transfer. Because the reaction efficiency depends on the size of the contact surface. The design of parallel surfaces will prevent the inner side of the ring from coming into contact with liquid. A packed tower is a type of tower equipment. Fill the tower with appropriate height of packing to increase the contact surface between the two fluids. For example, when applied to gas absorption, the liquid enters through the distributor at the top of the tower and descends along the surface of the packing. The gas flows upstream from the lower part of the tower through the pores of the packing, and interacts closely with the liquid. The structure is relatively simple and maintenance is convenient. Widely used in gas absorption, distillation, extraction and other operations. Gas is sent from the bottom of the tower, distributed through a gas distribution device (small diameter towers generally do not have gas distribution devices), and then continuously flows against the liquid through the gaps in the packing layer. On the surface of the packing, the gas-liquid two phases are in close contact for mass transfer. A packed tower belongs to a continuous contact gas-liquid mass transfer equipment, and the composition of the two phases changes continuously along the tower height. Under normal operating conditions, the gas phase is a continuous phase and the liquid phase is a dispersed phase. The main purpose is to support the packing inside the tower, while also allowing the smooth passage of gas-liquid two-phase flow. If not designed properly, the liquid flooding of the packed tower may first occur on the packing support device. The structure of the stepped ring packing is similar to that of the Ball ring packing, with rectangular small holes on the ring wall and two layers of cross shaped blades staggered at 45 ° inside the ring. The height of the ring is half of the diameter, and one end of the ring is a flared edge. This structure improves the performance of the stepped ring packing on the basis of the Bauer ring, increasing its production capacity by about 10% and reducing pressure drop by 25%. Moreover, due to the multi-point contact between the packing, the bed layer is uniform, effectively avoiding the phenomenon of channel flow. Stepped rings are generally made of plastic and metal, and have been widely used due to their superior performance compared to fillers with holes on other sidewalls.
