ABSTRACT:
Disclosed is a contaminated waste steam heat recovery apparatus 10 and method therefore which includes a primary condensing unit 38, a low pressure water washing unit 26, a liquid to liquid heat exchanger 36 and a vent fan 31. Waste gas is ducted from fryer 11 to a de-super-heating chamber 14 wherein superheated steam is converted to saturated steam by spraying water into the steam using spray nozzles 15. The gas is then introduced into a vertically disposed air to liquid heat exchanger 16 and is drafted downward therethrough. As heat is removed from the waste gas, water vapor in the steam condenses and in the process, collects some of the oil and hydrocarbons present. A plurality of condensate trays 19 are disposed below the bottom end of heat exchanger 16 in a cascading fashion to collect hold the condensate in the airflow path such that it will absorb some of the heat still present in the remaining waste gas. An oil outlet 22 is provided at the top of collection basin 22 for drawing off concentrated oil 23. The waste gas is pulled into a low pressure water washer 26 where it is washed by a second set of spray nozzles 15. Waste gas and water are sucked downward through a set of turbulence inducing baffles 28. The remaining waste gas is sucked out though exhaust tube 30, using vent fan 31, and vented to the atmosphere.
