PURPOSE:To realize a reduction of the energy to be consumed, by adapting the immersing method and the spray method for the predegreasing zone and the main degreasing zone respectively for the processor having a successive disposition of zones for the exhaustion, predegreasing, main degreasing, washing by water, chemical treating and washing by water respectively. CONSTITUTION:The phosphating apparatus processor for the metal to be processed has a successive disposition of exjaistopm zone 1, predegreasing zone 22, main degreasing zone 23, the first washing zone 4, chemical treating zone 5 and the second washing zone 6 respectively. For the degreasing zones, the conventional method is changed, i.e. the immersing method and the spray method are adapted for the zones 22 and 23. And in order to enclose the heat energy into the zones, the air curtain 13 is provided before and after the zones 22, 23 and 5 respectively. As a result, the quantity of vapor reaching the zone 1 can be reduced, and then the flowing of the vapor within the booths is sopped to save the energy consumption. |
