Numerical Simulation on the Recovery Process of Acid Pickling Waste Liquor by Jet-Flow Pyrolysis

Technical Article


The direct discharge of hydrochloric acid pickling waste liquor from iron and steel enterprises seriously wastes resources and pollutes the environment. In this study, a Venturi jet-flow pyrolysis reactor was used to fabricate iron oxide and recover waste acid. Combustion, phase transformation, and gas-solidification reactions were numerically simulated in this independently-invented Venturi jet-flow pyrolysis reactor. Fluent software was combined with user-defined functions to describe the fluid flow characteristics and the distribution rules of each component during jet-flow pyrolysis in the reactor. Then, the velocity, temperature, and component concentration distributions in the reactor were analyzed. The results presented in this paper can provide a theoretical basis to study the pyrolysis treatment of hydrochloric acid pickling waste liquor, as well as data support for optimizing a Venturi jet-flow pyrolysis reactor.
