Process device for coating denitration catalyst slurry

Abstract

The invention discloses a process device for coating denitration catalyst slurry. The process device comprises a substrate (1), an air hood (2) and an air cylinder (3). The substrate adopted by the process device is provided with an upper cavity and a lower cavity; a seal ring and an expansion contraction ring are arranged on the upper edge of the upper cavity; a lower air connector, an exhaust connector and a slurry connector are arranged at the upper part of the substrate, wherein the lower air connector is communicated with the expansion contraction ring, the exhaust connector is communicated with the middle part of the upper cavity, and the slurry connector is communicated with the lower part of the upper cavity; the air hood is provided with an upper air connector and a lifter, the air hood is positioned above the substrate, and the lifter is fixed on the substrate; the air cylinder is positioned in the lower cavity, and a piston rod of the air cylinder is connected with a support and is positioned in the upper cavity; during working, the technical scheme that firstly vacuum is utilized for absorbing slurry to the upper end face of a honeycomb carrier from downwards to upwards along honeycomb-shaped micropores and then compressed air is utilized for blowing the slurry away from the honeycomb carrier from upwards to downwards along the honeycomb-shaped micropores is adopted to complete coating, the production of honeycomb carrier coated slurry is realized, and the purposes of improving the working condition, alleviating the strength, eliminating the waste, improving the efficiency and reducing the cost are achieved.
