A method and example are considered for determining the optimal specific gas loading for a granular filter with connected structure. Calculations are performed on the dependence of the total costs on the specific gas load for the conditions of removing dust from flue gases.Protecting the environment and industrial locations from dust discharges requires efficient trapping of definitive dust products and high-grade cleaning from dust for outgoing technological gases and ventilation discharges [1][2][3][4][5].The commonest method of removing particles from a dusty gas is passage through a granular filter, which enables one to avoid exceeding permissible discharges to the air and to organize waste recycling in some processes [1]. Advantages of Granular Filters:The filter material is readily available and quite cheap; it provides a high degree of cleaning; it has strength and thermal stability in combination with good permeability and capacity to resist sharp changes in pressure; it is stable against corrosion and rusting; there are no electrocapillary phenomena; it can be regenerated by various methods; and individual filter elements are easily combined in a variety of ways.Basic Types of Granular Layer: • immobile freely poured or packed in a certain fashion granulated material; • periodically or continuously mixing of the material; and • material with a connected structure (sintered or pressed metal powders, glass, graphitized carbon, porous ceramics and plastics, and so on). However, granular filters for removing dust from gases are of restricted use because of the high cost of the filters. The surface area of the filter and consequently the cost can be reduced by increasing the specific gas loading q, but then the pressure difference across the filter ∆p and the energy consumption E increase. The optimum value of the specific gas load q opt is determined by the minimal sum of the total costs C 0 for performing the process: the cost C for the content and servicing of the filter, the amortization allowance A, and the energy cost E [8].We consider a method of determining q opt for a granular filter with connected structure (e.g., porous metal), whose total cost usually substantially exceeds the cost of packed filters [1].
