DEEP RECOVERY SYSTEM FOR RESIDUAL HEAT OF FUME

摘要

Disclosed is a deep recovery system for residual heat of fume. The recovery system comprises an upright thin-wall hollow tubular housing (1), a rotating core (2) coaxially provided on an upper part of the housing (1) and capable of rotating relative to its own central axis, a partition plate (3) provided in the housing (1) and passing through the central axis of the housing (1) and the rotating core (2), a baffle plate (4), a spray device (5), and a water-water heat exchanger (6) connected to a heat emission unit and a water inlet and a water outlet of the spray device (5), wherein the rotating core (2) is of upright thick-wall hollow tubular shape, the longitudinal cross section of a side wall of the rotating core (2) is honeycomb-shaped, and the interior thereof is filled with a moisture-absorbent material; the partition plate (3) divides the internal space of the housing (1) and the rotating core (2) into an air flow channel (8) and a fume flow channel (9); multiple baffle plates (4) are respectively provided between the top of the housing (1) and the top of the rotating core (2), between the top of the rotating core (2) on the side of the fume flow channel (9) and the top of the partition plate (3), between the bottom of the rotating core (2) on the side of the air flow channel (8) and the partition plate (3), and between the bottom of the rotating core (2) on the side of the fume flow channel (9) and the housing (1); and the spray device (5) is provided in the fume flow channel (9) at a lower part inside the housing (1).
