Title:
A DEVICE FOR UNIFORM DRYING OF COATED MONOLITH USING MONOTONOUS HOT AIR DISTRIBUTION
Document Type and Number:
WIPO Patent Application WO/2023/007310
Kind Code:
A1
Abstract:
The present invention is "A device for uniform drying of coated monolith using monotonous hot air distribution". One of the main steps in the automotive exhaust gas catalyst production process is the monolith drying step after wash coating. The purpose is the controlled evaporation of the moisture of the coated slurry in order to stabilize the slurry on the monolith channel walls. A continuous dryer based on a hot air system is designed in which by proper and uniform direction of hot air to the interior of monolith channels, uniform drying speed and consequently uniform distribution of precious metals in the catalyst is maintained between different channels and the heat efficiency of the process is increased. Besides, the proposed device operates continuously and, unlike conventional equipment, will require only one operator for continuous operation. The design is modular and it is possible to easily change the type of loaded monolith.
