BX500 Type Wire Mesh Corrugated Packing The CY700 Type Stainless Steel Wire Mesh Regular Packing is a general-purpose regular packing, which accounts for the vast majority of regular packings currently used in industry. The corrugated packing is a disk-shaped packing composed of many corrugated thin plates, with a compact structure and regular arrangement. The specific surface area can be adjusted by the shape of the corrugation structure; the angle between the corrugation and the tower axis is mainly 30° and 45°. The packing disks are vertically installed inside the tower, with adjacent corrugated plates overlapping in opposite directions during assembly. The adjacent packing disks are arranged at a 90° angle to each other, which causes the rising gas stream to continuously change direction and the descending liquid to be redistributed. This vertical arrangement allows for thorough mixing of the fluid within the tower, thus achieving a high mass transfer efficiency. However, corrugated packing is not suitable for materials with high viscosity, prone to polymerization, or containing suspended particles. Additionally, the installation and cleaning of the packing are difficult, and the cost is relatively high.

BX500 Wire Woven Corrugated Packing, CY700 Stainless Steel Wire Mesh Corrugated Packing can be divided into two main categories based on material: wire woven corrugated packing and plate corrugated packing. The wire woven corrugated packing is further categorized into metal wire mesh and plastic wire mesh, while the plate corrugated packing materials include metal, plastic, and ceramic. In recent years, the development of new high-efficiency structured packings has mainly focused on metal plate corrugated packing and metal wire mesh corrugated packing, especially after surface treatment through physical and chemical methods, which significantly enhances separation efficiency. In summary, the main advantages are: ① High theoretical plate number with high throughput and low pressure drop; ② Excellent low-load performance, with the theoretical plate number increasing as gas load decreases, nearly without a low-load limit; ③ Significant improvement in scale-up effects; ④ Provides favorable conditions for the distillation separation of difficult-to-separate systems, heat-sensitive materials, and high-purity products, fully meeting the requirements of precise, large-scale, and high-vacuum distillation units.

BX500 Type Screen Wavy Filling Material, CY700 Type Stainless Steel Screen Regular Filling Material is a disc-shaped regular filling material composed of vertically arranged screen wavy strips. The specific surface area value has a decisive impact on the mass transfer performance. Depending on the specific surface area, the screen wavy filling material can be divided into 250m2/mi, 350m2/m3, 500m2/m3, and 700m2/m3 types. Due to the dense screen, the void ratio is high, reducing the pressure drop of the filling layer. The unique capillary action of the screen makes it easy for the liquid to form a film-like distribution on the filling surface, with a thin liquid film and small holding capacity, thus exhibiting excellent wettability and high separation efficiency. The drawbacks are the high cost, susceptibility to clogging, and fear of corrosion. Metal wire mesh wavy filling materials are commonly used in vacuum distillation, atmospheric distillation, and absorption operations; plastic mesh wavy filling materials are suitable for general absorption processes below 80℃.
