Application of Automatic Caustic Washing Device in Hydrogen Peroxide Production by Anthraquinone Method
In the production of hydrogen peroxide by anthraquinone method,because the clay bed cannot completely regenerate the inert degradants produced by the side reaction into effective anthraquinones,the inert degradants continue to accumulate in the process production and affect the physical properties of the working liquid,resulting in the reduction of extraction efficiency and the reduction of hydrogen peroxide production capacity,and alkali washing has become a solution for the treatment of inert degradants.With the iteration of the process,the automatic caustic washing device has been gradually put into use,and compared with the traditional caustic washing process,it can intermittently lead 0.3%-0.5%of the circulating working liquid out of the main device for caustic washing.It can effectively improve the safety and reliability in the production process of hydrogen peroxide,reduce the investment of fixed assets and production and operation costs,and the complete set of automatic caustic washing equipment with a small area has more operability in today's promotion of all-acid working fluid system.
