Description

Technical Field

[0001] This utility model relates to the field of catalyst regeneration technology, and in particular to a device for regenerating automotive exhaust catalysts. Background Technology

[0002] A catalyst can be defined as a substance that can increase the rate of a chemical reaction without changing the chemical equilibrium, and whose mass and chemical properties remain unchanged before and after the chemical reaction. During the use of automotive exhaust catalysts, impurities such as soot particles will adhere to the surface, pores, and gaps of the catalyst. These impurities will affect the contact area between the catalyst and the reactants, thus affecting the reaction efficiency. However, catalysts can usually be regenerated, and the regenerated catalyst will restore its catalytic ability.

[0003] In the relevant catalyst cleaning and regeneration equipment technology, the catalyst is simply rinsed. During the cleaning process, the catalyst will accumulate inside the cleaning tank. The catalyst is piled up and it is difficult to rinse the accumulated catalyst inside. In addition, simple rinsing will leave impurities such as soot particles attached to the catalyst pores and gaps, which are difficult to be directly washed away. As a result, the catalyst will still contain a large number of soot particles and other impurities, resulting in poor regeneration effect. Utility Model Content
