Metal wire mesh packing with metal plate inserts, and wire mesh corrugated packing with anti-wall flow rings, suitable for vacuum distillation of thermally sensitive, difficult-to-separate systems under conditions with operating pressures below 7KPa, such as requiring fewer theoretical plates but lower pressure drop.

The 700Y metal wire mesh packing for the distillation column and the BX500 type mesh corrugated packing are formed by compressing the corrugations and mesh into several layers. The corrugations have a tilt angle of 30° or not 45°, with adjacent corrugations facing opposite directions. When installing the packing from the tower, the three packs should be stacked at a 90° angle to each other. The regular packing, due to its regular, uniform, and symmetrical structure, defines the vapor-liquid flow path, improves the phenomena of沟流 and wall flow, and boasts advantages such as low resistance, high throughput, and good分流 efficiency. It is widely used in the tower equipment in various fields of fine chemicals and petrochemicals.

Filling material features and functions

1. This type of packing is made of metal wire mesh filled with metal sheet strips, featuring a screen corrugated packing with a wall-flow prevention ring, constructed from four metal sheets, each approximately 0.2mm thick.

2. The plate has punched holes, with a hole rate of 10% on each side. The latter mainly serves to increase the lateral mixing of gases, ensuring an even distribution of the liquid in general.

3. The sheets are then stamp-formed into four pieces with a significant slope or wavy design.

Product Advantages Significance

1. Metal wire mesh packing with metal plate inserts and woven wire packing with anti-wall flow rings exhibits high separation capabilities. BX packing, with its broad operational range, boasts significant capacity.

2. They are formed into corrugated sheet materials by several parallel and metal wire mesh stamping processes, which are then vertically stacked and assembled into disk-shaped packing.

3. They offer excellent separation performance, such as high selectivity and separation capacity.

4. These types of fillers are widely used in difficult-to-separate systems and in precise distillation, as they are highly favored for their high mass transfer efficiency under low pressure drop.

Metallic wire mesh packing with metal-encased sheets and screen corrugated packing with anti-overflow rings are primarily used in a variety of precise separation, fine separation, high-purity separation, deep cryogenic separation, and air separation applications. The packing layer per meter can provide 3-12 different theoretical stages, significantly reducing the tower height. Caution: Be cautious when using for systems with high liquid-gas ratios, strong corrosiveness, clogging systems, high surface tension, and high viscosity. The main difference between BX500 screen corrugated packing and CY700 screen corrugated packing lies in the different specific surface area and wave peak spacing. The larger the specific surface area, the greater the treatment capacity, but the higher the resistance will also be. Choosing packing with a larger specific surface area within the tower will yield better results, but ultimately, selecting the appropriate product based on our tower conditions, flow rate, resistance, etc., is key to achieving good performance.
