1. a water spray type thin plastic film flue gas waste-heat recovery device is characterized in that, utilizes the form of water spray type heat exchanger, adopt thickness be 50-250 μ

  • m plastic sheeting as the heat exchange material, substitute traditional metal heat exchange material, process film bundle heat-exchanging component;

    The vertical mode of film bundle heat-exchanging component is placed in the housing;

    Falling liquid film flows trickle on film bundle heat-exchanging component surface under the gravity effect;

    The heat of flue gas in the absorbing film bundle heat-exchanging component;

    Be connected with the end film between film bundle heat-exchanging component and the housing, adopt spot-welded on, the stretch-draw of equidistance silk ribbon or keel to support between two adjacent films;

    The end film (20) of film bundle heat-exchanging component and shell plates (17) adopt welding, bonding or bolt to be connected, to completely cut off fume side and trickle side;

    According to the heat exchange needs, a plurality of film bundle heat-exchanging components are corresponding up and down to be placed, and the flue gas multipaths is flowed, and trickle adopts single flow process from top to bottom, makes the approximate countercurrent heat-transfer that conducts heat, thereby water vapour is progressively freeze-outed, and realizes utilizing the latent heat of water vapour in the flue gas.
