Diesel fuel heated dessicant reactivation with same direction reactivation and processed air flow

Abstract

Dessicants employed in dehumidifying moisturized air present within a water-damaged building are themselves dehumidified to liberate collected moisture through the use of ambient air drawn over and about a heat exchanger fired by diesel fuel, in which the moisturized air and the ambient air are drawn through the dessicant in the same direction.

1 . Apparatus for dehumidifying moisturized air present within a building from a point external thereto having an enclosure housing a heat exchanger, a dessicant, a first blower drawing ambient air from outside said enclosure over said heat exchanger through said dessicant in a first direction, a second blower drawing said moisturized air through said dessicant in a second direction, and means for firing said heat exchanger with diesel fuel, wherein said first blower and said second blower draw said ambient air and said moisturized air through said dessicant in the same direction.  
   
   
       2 . The apparatus of  claim 1  wherein said dessicant includes a silica gel composition.  
   
   
       3 . The apparatus of  claim 1  wherein said dessicant includes a rotating silica gel wheel.
