Metal ball ring filler is widely used in chemical industry and other industries, to be used for medium separation, is an improvement on the basis of the Lacey ring, the ring wall has two rows of windows with extended tongue, each window has five tongue, this kind of arrangement improves the gas-liquid distribution and makes full use of the inner surface of the ring. In the prior art, the manufacture of stainless steel ball rings requires three processes, namely, breaking, bending and rounding, thus requiring at least two sets of dies, affecting production efficiency, and not using human and material resources rationally. The invention of a new manufacturing process for a ball ring aims to make up for the shortcomings of the existing technology and provides a mold capable of forming the ball ring at one time. A ball ring is formed once. The die comprises an upper die and a lower die, the lower die is composed of a base and a worktable, and the base and the worktable are supported and connected by guide pillars, the lower end of the crucible is used for forming the tongue die of the tongue page of the Bauer Ring, and the upper die is arranged side by side with the trimming and bending die. Feed the crucible into a"Darn" shape. The die with the tongue shape of a knife is fixedly connected on the base, and the die with the tongue is divided into two rows of three in each row, and the die is detachably installed on the punch. After adopting the practical new structure, the stainless steel ball ring can be made by using a set of mould, which saves the labor and improves the working efficiency and greatly reduces the manpower and material resources. The specific implementation of the Bauer Ring The following is a step-by-step explanation of the concrete embodiment of the utility model. The one-time forming die for the Bauer Ring in this embodiment comprises an upper die and a lower die. The lower die is composed of a base and a worktable. The base and the worktable are supported and connected by guide pillars. One side of the worktable is provided with four parallel sliding blocks. The other side is provided with a forming die for fixing the ball ring into a shape. 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.
