Description

Technical Field

[0001] This utility model relates to the field of wire mesh packing technology, specifically to a wire mesh packing. Background Technology

[0002] Wire mesh packing is a type of packing material arranged in a uniform geometric pattern and neatly stacked within a column. Due to its advantages such as large specific surface area, low pressure drop, uniform fluid distribution, and high mass and heat transfer efficiency, it has been widely used. Wire mesh packing is the main form of corrugated mesh packing, with its main body made of wire mesh. Wire mesh corrugated packing has high separation efficiency and is particularly suitable for precision distillation and vacuum distillation equipment, providing an effective means for the distillation of difficult-to-separate systems and heat-sensitive systems. Silicon carbide wire mesh packing is a type of packing material. To improve the structural support of the wire mesh packing, silicon carbide wire mesh packing has silicon carbide slurry attached to an organic wire mesh and sintered to obtain an integrated packing structure. Silicon carbide wire mesh packing has good corrosion resistance and high-temperature heat resistance, and is widely used in high-temperature distillation operations.

[0003] Silicon carbide wire mesh filler uses organic wire as the wire mesh material. Organic wire mesh itself has poor structural support. After molding, the main structural stress of silicon carbide wire mesh filler is borne by the external silicon carbide sintered layer. Although silicon carbide has high hardness, its own structure is brittle. When subjected to external pressure, the structure of silicon carbide wire mesh filler is prone to breakage and deformation, resulting in poor structural stability. Therefore, a wire mesh filler is proposed. Utility Model Content

[0032] The working principle or structural principle is as follows: During processing, a wire mesh structure is formed by mixing and weaving support wires 5 and organic wires 6. This wire mesh structure is then placed in a stamping machine and formed into a corrugated mesh structure through stamping. Silicon carbide slurry is then attached to the upper part of the wire mesh and sintered to obtain an integrated filler structure, completing the filler processing. During installation, the filler core 1 is first aligned and installed into the interior of the mounting frame 2. Then, multiple support bolts 9 are sequentially inserted and tightened into the screw holes on the side of the mounting frame 2. The support bolts 9 provide support and limit for the filler core 1. After completion, the lifting bolts 11 are tightened into the screw holes on the upper part of the mounting frame 2. Using the hoisting bolt 11 as the tether point for the hoisting rope, the entire packing is placed into the distillation column through the hoisting device. During placement, the packing is positioned by the engagement of the positioning protrusion 8 at the bottom of the mounting frame 2 with the upper groove of the mounting base. Then, the upper packing is positioned and installed in the same manner. During the installation of the upper packing, the positioning protrusion 8 is engaged with the upper positioning groove 7 of the lower mounting frame 2 to position the packing. After the positioning is completed, the fastening bolt 10 is inserted into the screw hole at the top of the mounting frame 2. After the fastening bolt 10 is inserted through the mounting frame 2, the mounting frame 2 is tightened with bolts to limit the installation and complete the packing installation operation.
