Method for Coating the flow channels of a monolithic Catalyst Support body with a dispersion Coating

摘要

A method for Coating the flow channels of a monolithic Catalyst Support body has a Cylindrical shape with a dispersionde CoatingThe bearing body has two end Faces are conectadasent re prepared by Parallel Flow channels away from the Cylinder.By means of the vertical orientation of the Cylinder Axis of the bearing body.The application of a Predetermined amount of storage from the dispersionde Coating deposit on the face and upper body support the aspiration of dispersion atThrough Flow channels, removing the excessive dispersion Coating out of the flow channels through libera tion by blowing the flowThe recovery of excessive dispersion to the Storage Tank and the fixing of the coating dispersion by means of unacalcinacion.The method is characterized by the fact that in the dispersion of coating with a flow rate of 0.1 to 1 m / s through Flow channels.And after the aspiration removes excessive dispersion Coating outside the channels to flow through the application of a Pulse Aspiration from below,Where is the Suction Air Flow With a Speed of between 40 and 1 m / s through Flow channels and separates the coating dispersion which llevacon excessive CurrentAir Out of the Air Stream within a Time less than 100ms. After the departure of The Catalyst Carrier body.
