Filters For Cleaning Gases From Radioactive Aerosols

Metal ceramic filters are designed for deep cleaning of industrial gases and air from radioactive aerosols and radioactive particles, as well as for separation of dust and gas mixtures in gas-plasma dry-conversion facilities for uranium hexafluoride.

Terms of Use

Operating temperature: not more than 750 ° С
Relative humidity: not more than 80%
The efficiency of purification from particles with a size of ≥ 0.15 μm: not less than 99%
Dependence of pressure drop on gas filtration rate up to 1 m / s: linear

Advantages
  • high mechanical strength;
  • corrosion resistance to filtered gases, chemically inert to the material of the filter element;
  • low pressure drops at high gas flow rates;
  • long service life, the ability to regenerate and restore characteristics.
Material used
  • nickel;
  • steel 20;
  • nickel mesh and sintered nickel powder;
  • copper (for mounting rings).
