PURPOSE:To permit to wash an air ejector without dismantling it by a method wherein air ejector inner wall washing fluid supplying conduit is connected to an air supplying pipeline connected to the nozzle of the air ejector in the titled apparatus equipped with the air ejector and a water sealing type vacuum pump. CONSTITUTION:In the titled apparatus, the reaction gas, induced into a reaction chamber 1 from the direction of an arrow sign A, is sucked into an exhaust conduit 2 through an exhaust port 1a, subsequently, is exhausted into the direction of the arrow sign B through the air ejector 7 and the water packing type vacuum pump 8. The driving source of the air ejector 7 is air discharged from first and second mechanical boosters (vacuum pumps) 3, 5 and the air supplying conduit 7b. In this case, a branched conduit 14 for supplying the washing water is connected to the air supplying conduit 7b in order to permit the washing of the air ejector 7. Upon washing the ejector 7, opening and closing valves 11, 12 are closed, another opening and closing valve 13 is opened and the washing water from the branched conduit 14 is injected into the ejector 7 to remove solid materials adhering to the inner wall of the ejector 7. |
