Wire Mesh Padding
Wire packing the detailed introduction£º
The metal screen corrugated metal screen referred to packing. Corrugated metal screen is the world is widely efficient packing, it is by the number of parallel inline corrugated metal nets arranged composition disc packing, corrugated axis inclination to 30 degrees or 45 degrees, and the adjacent two pieces of corrugated piece in opposite directions. Corrugated metal screen with high spicific surface, pore ratio, light weight; Gas interlinked, have little inclination of road rules, pressure reduction; Radial diffusion good gas contact, fully, almost no low load limit and large elasticity of operation etc. Characteristics. Apply to difficult to separate and heat in the department of atmospheric distillation, that vacuum distillation, etc.
The metal screen corrugated advantages:
Wire packing is this world is widely efficient packing, its main advantage is:
1. The number is high, the flux theory board, reduced pressure;
2. Low load performance is good, theoretical tower number with gas load decreases and increased, nearly no low load limit;
3. Operating flexibility;
4. Amplification effect is not obvious,
5. Can satisfy the precision, large, high vacuum distillation device requirements. Separate matter is difficult, heat of high purity and products that rectification separation provides favorable conditions.
Wire packing mainly with nets specifications:
Material: 304, 304 L, 316, 316 L, etc
Nets specification: 60Ä¿*0.15£¬60Ä¿*0.12£¬,5Ä¿*0.17,50Ä¿*0.15µÈ
80/60Ä¿*0.16,102/60Ä¿*0.16
