A mutistage fluidized bed heat exchanger for waste water heat recovery from multitype heat sources

摘要

The present invention relates to a multi-stage waste heat recovery fluidized bed heat exchanger for multiple heat source simultaneous heat recovery, a heat recovery system using a fluidized bed heat exchanger, and a heat recovery method. And more particularly, to a water fluidized bed heat exchanger including a body having an exhaust gas inlet through which waste steam generated in an industrial process and waste steam flows in and an exhaust gas outlet through which exhaust gas cooled at the other end is exhausted; And a plurality of water inflow holes formed in the water fluidized bed, the water inflow passages being provided in the body, the water inflow passages being formed in the body, A multi-stage water fluidized bed unit in which the heat transfer pipe is immersed and absorbs latent heat and sensible heat of condensation of the waste gas and the waste steam to heat the water supply; And at least one of a plurality of water fluidized bed units, and a wasted hot water inlet for introducing the waste hot water generated in the industrial process to the multi-stage water fluidized bed heat exchanger for simultaneous heat recovery of multiple heat sources.
