ABSTRACT:
A deicing fluid recovery system for aircraft deicing apparatus includes a storage tank from which a deicing fluid/water deicing mixture is pumped through a line heater to a deicing fluid distribution and collection zone for application to the wings and fuselage of aircraft. Expended deicing fluid is collected in a drainage system incorporated into a concrete or asphalt pad and directed to a sump. Upon accumulation of a sufficient quantity, the diluted used deicing fluid is pumped to a sludge tank. Solids and free water are separated by settling and filtration processes in the sludge tank. The filtered deicing fluid mixture is heated through sequential heat exchangers and directed to a regenerator. The deicing fluid mixture is leaned by a dehydration process in the regenerator in which the mixture is heated and compressed air is injected to exhaust water from a stripping column. The lean deicing fluid flows over an overflow weir into an accumulator. The heated and leaned deicing fluid mixture then is passed back through the sequential heat exchangers, as a heat source, and pumped back into the storage tank for subsequent reuse.
