INDIRECT-HEAT HOT AIR BLOWER FOR DEODORIZATION

摘要

PURPOSE: An indirect-heat hot air blower for deodorization is provided to heat stalls and work places of pigpens in the winter season and to secure pleasant indoor environment by removing external polluted air. CONSTITUTION: An indirect heat hot air blower for deodorization is composed of a burner(2) for receiving and burning fuel and air from the outside; a furnace(6) for supplying a moving path passing combustion gas burnt in the burner; a heat-exchanging unit(8) disposed to the outer wall of the furnace to receive heat from the high-temperature combustion gas; a first heat exchanger(10) connected and installed to the end of the furnace to pass the high-temperature combustion gas and first preheat the air; a first air inlet port(16) disposed to the side of the first heat-exchanger to receive the air from a blower(14); a first air discharge port(18) arranged to the first heat exchanger to discharge the preheated air; a second air inlet port(20) for flowing in the air discharged from the first air discharge port; a second heat exchanger(12) for secondarily preheating the air flowing into the second air inlet port; a second air discharge port(22) installed to the second heat exchanger to discharge the secondarily preheated air; a third air inlet port(24) connected and installed to the second air discharge port to flow in the secondarily preheated air; a catalytic bed(4) for removing pollutants in the air flowing into the third air inlet port; and a third air discharge port(26) for discharging the air passing through the catalytic bed.
