  • Patent number: 9796632
    Abstract: A method of manufacturing a ceramic filter for hot gas filtration, and, more particularly, to a method of manufacturing a ceramic filter for hot gas filtration through a drying process. The ceramic filter manufactured by the method is advantageous in that the pore size thereof can be easily adjusted, and the filtering area thereof can be maximized, thus improving the performance thereof. Consequently, the method of manufacturing a ceramic filter can be usefully used in the filter-related industry because a high-performance ceramic filter can be manufactured at a low cost and at low energy.
    Type: Grant

  • Patent number: 8431187
    Abstract: Disclosed herein is a method of producing a filter medium for treating medium and high temperature exhaust gas using foam coating and a filter medium produced using the method. The filter medium has excellent heat resistance and heat contraction resistance, and exhibits partial dust collection efficiency of 99% or more by weight, total dust collection efficiency of 99.999% or more by weight, and high dust removal efficiency, for all dust particle sizes. Further, the filter media can be efficiently used to treat medium and high temperature exhaust gas because pores having an average pore size of 30 ?m or less are uniformly distributed on the surface of the filter media.
