Packed Bed Scrubbers

Packed Bed Scrubbers is used to purify hazardous exhaust gas through its internal special filling pieces, which enlarge the surface between exhaust gas and fluids. The entire pollution control system consists of the following equipments and components Scrubbers (Packed bed, sieve tray and venturi scrubbers), Centrifugal exhaust blowers, fume collection hoods, ducts, stack or chimney. The capacity is up to 100m³/hr to 1000,000m³/hr. These are perhaps the most important & wide used gas scrubbers. The packed bed scrubbers, packed with hollow thermoplastic elements remove soluble gases like HCL, CL, BR₂ and NH₂, S0₂ H₂S & NO_x. The thermoplastic elements are fluidized by the ascending gas stream as it passes counter to the descending scrubbing liquid. The efficiency of the scrubber is the function of interfacial area between the gas, the liquid and the turbulence at the interface. The packing area not only provides a high interfacial area per unit volume but also ensures uniform distribution & flow of the liquid over it. The column diameter is designed based on the gas and liquid flows and the column height is designed based on the required concentration.
