DRYING FURNACE

Japanese Patent JP3655461

B2

PROBLEM TO BE SOLVED: To reduce the labor required for cleaning the inside of a drying furnace, such as the drying furnace for painting, drying furnace for printing, etc., and, at the same time, to reduce the burden of an exhaust gas treating device.
SOLUTION: A water electrolysis accelerating material 16 prepared by kneading the powder of a pyroelectric material with a heat-resistant organic adhesive is applied to the exposed internal surface 14 of the furnace casing 2, such as the furnace wall, etc., of a drying furnace. When the material 16 is heated as the temperature in the furnace rises, minus electric charges appear on the exposed internal surface 14 of the furnace casing 2 due to the pyroelectric effect of the material 16. When an evaporated organic solvent which is produced at the time of drying the coating film is condensed on the exposed internal surface 14 of the furnace casing 2, etc., and the condensed solvent adheres to the surface 14, etc., as gum, part of water molecules contained in the gum receives the electrons which appear due to the pyroelectric effect of the material 16 and electrolyzed into hydrogen and ionized oxygen. Since the ionized oxygen reacts to the organic matter which is the main component of the gum and dissolves the organic matter into water and carbon dioxide through oxidation, the quantity of the gum can be reduced.
