Recovering heat and dust from hot waste gases - by thermodynamic action on liq. layer

摘要

In recovering both heat and suspended particles from high-temp. fluid or heat only from a suspension-free fluid, esp. from hot waste gases, heat is transferred from gas to water during dry cooling of the gas. The system utilises the intensive heat exchange at the surface of turbionar-quasi compressible thermal layers. After partial cooling, incoming dusty gas is fed by a central distributor into a series of tubular units for sepg. dust, with the purged gas then further cooled by sec. heaters inside a boiler. A tert. heater with descending inclined tubes then transfers retained particles into a bunker, while corresp. rising tubes collect hot gases, and further descending tubes distribute cooled gases from the boiler into a fixed collector. ADVANTAGE - No compressed air is needed, and clogging by dust is largely avoided.
