    摘要: A drying furnace for use in coating drying in which a hot gas recycling duct for emitting radiation heat is disposed on the inlet zone of a tunnel-like furnace main body and resin-removing ducts are disposed along the ceiling of the inlet zone and the exit zone of the furnace main body respectively, wherein the furnace main body is turned in a U-shaped configuration so that the inlet and the exit thereof are arranged side by side, and the hot gas supplied to the hot gas recycling duct is supplied to each of resin-removing the ducts. Resinous substances can surely be prevented from forming and depositing at both of the inlet and the exit of the furnace and the cleaning work for the resin-removing ducts can be saved.

    摘要: A method of operating an air-supplied type coating booth in which conditioned air supplied from an air supply blower is enforced downwardly to the inside of a tunnel-shaped coating booth and the air in the coating booth is drawn together with paint mists and the likes down to the beneath of a booth floor by way of an air exhaust blower comprises the steps of detecting the flow velocity of air streams flowing into or out of inlet and the exit of the coating booth, applying primary and secondary averaging processings for signals for averaging variations caused by external disturbances fluctuating at relatively shorter and longer periods of time, judging the thus averaged direction and the flow velocity of the air streams at the inlet and the exit, variably controlling the flow rate of exhaust from the exhaust blower in accordance with the direction and the flow velocity. The exhaust blower means are divided into a plurality of blowers and the minute variations in the direction and the flow velocity are controlled excessively by the blowers situated at the inlet and the exit of the coating booth, while remaining exhaust blowers are operated at predetermined flow rate.

    摘要: A method of operating an air-supplied type coating booth adapted to enforce conditioned air by an air supply blower through a filter downwardly to the inside of a tunnel-shaped coating booth at a predetermined flow velocity and then drawn to discharge together with coating mists, etc. to the beneath of the floor comprises the step of detecting the flow velocity of conditioned air flowing through the filter to the inside of continuously, applying primary and secondary averaging processings for the detected signals containing variations fluctuating at relatively shorter and longer periods respectively, comparing the value obtained from the signals applied with the secondary averaging processing with a predetermined flow velocity value and variably controlling the flow rate of the air supplied from the air supply blower depending on the deviation and thereby maintaining the flow velocity of the conditioned air flowing to the inside of the coating booth always constant. Reduction of the flow velocity supplied to the inside of the air-supplied type coating booth due to the filter clogging can be compensated exactly with no effects of external disturbances.

    摘要: An exhaust gas processing apparatus for a paint drying oven of this invention comprises a reaction container; a first catalyst layer disposed at an upstream side of the reaction container comprising a support of a honeycomb substance or a foamed substance, a carrier layer formed on the support and a platinum group element catalyst loaded on the carrier layer; a second catalyst layer disposed downstream of the first catalyst layer comprising a support of a pellet substance, a honeycomb substance or a foamed substance and a platinum group element catalyst; and a third catalyst layer disposed downstream of the second catalyst layer comprising a support, a carrier layer formed on the support and a copper-cerium-silver catalyst loaded on the carrier layer. Thus, the exhaust gas processing apparatus of this invention exhibits improved exhaust gases purifying abilities, even at relatively low temperatures, and less pressure drop.
