定义
A precision-engineered mesh screen component designed for catalyst baskets in chemical manufacturing reactors. It serves as a structural support and containment system for catalyst particles, ensuring uniform fluid distribution while preventing particle migration or loss. The screen's mesh geometry is optimized for specific catalyst sizes and process conditions to maintain optimal reaction efficiency and prevent pressure drop issues.
工作原理
Operates on the principle of size-based filtration and mechanical support. The woven or welded mesh structure creates openings smaller than the catalyst particles, physically containing them while allowing reactants and products to flow through. This maintains catalyst bed integrity, promotes even fluid distribution, and prevents channeling that could reduce reaction efficiency.
材料
Typically manufactured from corrosion-resistant alloys such as 316L stainless steelInconelHastelloyor titanium. Material selection depends on process temperaturepressureand chemical compatibility. Common specifications include ASTM A240 for stainless steel or equivalent international standards.
Mesh Size
10-100 mesh (2.00-0.149 mm openings)
Open Area
30-60%
Thickness
1-5 mm
Wire Diameter
0.5-2.0 mm
Pressure Rating
Up to 100 bar
Maximum Temperature
Up to 1000°C depending on material
标准

常见问题

What factors determine mesh screen selection for catalyst baskets?

Key factors include catalyst particle size (mesh must be smaller than smallest particles), chemical compatibility with process fluids, operating temperature and pressure, required open area for flow, and mechanical strength needs.

How often should catalyst basket mesh screens be inspected?

Regular inspection every 6-12 months is recommended, or during each catalyst changeout. More frequent inspection may be needed in high-temperature or corrosive environments to check for deformation, corrosion, or clogging.
