Description

Technical Field

[0001] The present invention relates to the technical field of structured packing, and specifically to a manufacturing method for corrugated structured packing of a dense gas-liquid flow purification tower. Background Art

[0002] Since the 1980s, structured packing has gradually shown advantages such as large throughput, low resistance, high efficiency, and convenient installation, and has been widely used in industrial fields such as petroleum, chemical industry, cryogenic engineering, and light industry. So far, structured packing has won a quite large market share in the equipment business of purification tower internals, and its market share is still further expanding.

[0003] Corrugated structured packing is a product with relatively excellent performance among many structured packings. It is usually made by pressing metal sheets such as stainless steel, aluminum, and copper into corrugated sheets with a triangular cross-section and assembling them into trays. The corrugations of the packing sheets generally form two angles of 30° and 45° with the tower axis direction. When the packing is assembled into trays, the corrugation patterns of adjacent two packing sheets are opposite, and the two trays of packing are placed vertically and staggeredly at 90°.

[0004] Chinese Patent discloses a manufacturing method for dense gas-liquid flow corrugated structured packing (authorization publication number CN109351319A). This patented technology uses metal strips made of stainless steel, aluminum, or copper to manufacture packing sheets. The packing sheets are punched using a punching die provided with gradually increasing blanking holes, so that this process can meet the requirements of punching gas-liquid distribution holes much smaller than the hydraulic diameter of the packing sheets and has a sufficient service life. It has the characteristics of reasonable design, simple structure, easy processing, effectively reducing the resistance loss caused by uneven gas-liquid in the use process, further improving gas-liquid distribution, reducing the resistance of the packing tray and the distillation column, and reducing operating energy consumption.

[0005] However, there are still deficiencies in view of this patent. Although this patent uses punching to produce the packing sheets, there will be burrs of different sizes in the holes after production, which will affect the uneven gas-liquid distribution. And after punching and long-term use, its strength is poor and it is prone to damage. Therefore, those skilled in the art have provided a manufacturing method for corrugated structured packing of a dense gas-liquid flow purification tower to solve the problems raised in the above background art.

[0007] To achieve the above purpose, the present invention provides the following technical solutions:

[0008] A manufacturing method for corrugated structured packing of a dense gas-liquid flow purification tower includes the following steps:

[0017] A2: After cutting, place the metal material on the grinding table for fixing. After fixing, start the grinding motor to work, so that the grinding roller can grind the cutting surface of the metal material, and then obtain a smooth cutting surface for subsequent use.

[0018] As a further scheme of the present invention: When punching the stainless steel, aluminum or copper in S2, use a punching die provided with a gradually increasing blanking hole to punch, so as to meet the punching of gas-liquid distribution holes much smaller than the hydraulic diameter of the packing sheet.

[0019] As a further scheme of the present invention: Bonding the gas-liquid flow corrugated regular packing sheets in S3 can make them finally form a disk, and after forming the disk, grind the punched holes.

[0020] As a further scheme of the present invention: The grinding process of the punched holes includes the following steps:

[0021] a1: After being spliced into a disc, the structured packing is clamped and fixed, and the grinding motor is started to rotate the grinding cylinder. The size of the grinding cylinder is adapted to the size of the punched hole, so that the grinding cylinder can rotate in the punched hole to grind the punched hole;

[0022] a2: After grinding one of the punched holes, the grinding motor can be moved to make the grinding cylinder correspond to the next punched hole, and then the next punched hole can be ground. Repeat the above steps to grind all the punched holes on the structured packing.

[0023] As a further solution of the present invention: in S4, when flushing the structured packing, water with a temperature of 45° C.-50° C. is used for atomized spraying, and the spraying needs to be performed from top to bottom.

[0024] As a further solution of the present invention: the drying in S4 is carried out by heating and drying, wherein the drying temperature is 55° C.-150° C., and the drying time is 1.5 h.

[0025] As a further solution of the present invention: the drying temperature in S5 is 85°C-95°C, the sintering temperature is 1250°C-1350°C, and the drying and sintering times are both 1.5 hours.

[0026] Compared with the prior art, the beneficial effects of the present invention are: the present invention uses metal materials made of stainless steel, aluminum or copper with a glossy surface to manufacture filler sheets, which can ensure that the structured packing produced is more beautiful and practical. At the same time, the punched holes are polished after punching, which can ensure that the inner wall of the punched hole is smooth, reduce the resistance damage caused by uneven gas and liquid, and further improve the gas-liquid distribution. In addition, by rinsing, drying, drying and sintering the structured packing after production, the strength of the structured packing can be improved, thereby increasing the service life of the structured packing.
