heat exchanger for cooling fluidized particles with backmixing and circulation modes.

摘要

HOT particulate material fluidised CHILLING IN A ZONE heat exchanger having an upper portion running in a circulation mode through it and a bottom portion operating in a fallback mode mix. Particulate material drops from a collection zone SUPERIOR TO INPUT A heat exchanger. EXCHANGER contains a series of tubes for indirect heat exchange MATERIAL WITH PARTICLE a fluid coolant. PARTICLE MATERIAL LEAVING THROUGH EXCHANGER an outlet at a central portion of the exchanger. EXCHANGER SECTION BETWEEN THE ENTRY AND CONSISTS OF CIRCULATION OUTPUT SECTION. Particulate material is further subjected to heat exchange BELOW exchanger outlet ON MIXING return portion. Fluidizing GAS TO INTRODUCE ON THE BOTTOM OF TURBULENCE Exchanger NECESSARY FOR PROVIDING THE EXCHANGE OF PARTICLE IN THE MIX RETURN PORTION OF COOLER AND FOR TRANSPORTATION PARTICLE THROUGH PORTION OF CIRCULATION Exchanger. METHOD AND FACILITATE THE EXCHANGE DESIGN INCREASED SURFACE AREA AND IMPROVED EXCHANGER WORK ON ELIMINATION OF HEAT RETURN PORTION MIXING Exchanger.
