Reaction-filtration integrated device for hydrogen peroxide hydrogenation section and hydrogen peroxide hydrogenation process

The invention relates to a reaction-filtration integrated device for a hydrogen peroxide hydrogenation section and a hydrogen peroxide hydrogenation process. The reaction-filtration integrated device comprises a backwash tank and a reactor; a backwash liquid in the backwash tank goes into the reactor in two or more paths; a pipeline mounted at the bottom of the backwash tank is divided into two or more branches which are connected to a backwash liquid inlet of the reactor; the backwash liquid inlet and a hydrogenated liquid outlet are formed in the reactor. According to the reaction-filtration integrated device for the hydrogen peroxide hydrogenation section, after a working liquid, hydrogen and a catalyst are added, the mixed working liquid is stirred by a stirrer and guided by a guide cylinder to wash a filter element inside the reactor with cross flows, and therefore, the service life of the filter element can be prolonged; meanwhile, the catalyst is put in sufficient contact with the working liquid so that the reaction rate is increased; the hydrogenated liquid generated after a hydrogenation reaction flows to the inner side of the filter element from the outer side of the filter element; the reaction-filtration integrated device overcome the defects of many hydrogen peroxide hydrogenated liquid filtering devices, complex structure, large volume, large floor area, high device investment and the like at present.
