Abstract

A cascaded oxidation reaction component includes several components stacked together to form at least one layer, each component is provided with a through hole, and the aperture ratio of the through hole is 2.5:1-25:1. The cascade oxidation reaction component provided by the present invention is composed of more than one layer of components, and the aperture of the lower component is smaller than the aperture of the upper component, so that the continuously consumed reaction raw materials continue to move to the lower layer as the volume becomes smaller. , during this movement, the gas-liquid redistribution is driven, and the reaction contact area of ​​the material is increased. Raw materials with different reaction rates are carried out on different reaction layers (that is, the larger ones are reacted on the upper member, and the smaller ones are reacted on the lower member) to form a three-dimensional cascade reaction system, which improves the production efficiency.

Description

technical field [0001] The present invention relates to a method for chemical reaction, in particular to a super-oxidation reaction method, as well as the organization for implementing the method, and the application of the component in iron oxide preparation device and production. Background technique [0002] Iron oxide is an important iron oxide. It is used as a colorant in paint, ink and rubber industries. It is also widely used in paint, rubber, plastic cosmetics, architectural fine grinding materials, precision hardware instruments, optical glass, Coloring of enamel, stationery, leather, magnetic alloy and advanced alloy steel, used as pigment for coloring of paint, rubber, plastic and construction, as well as polishing agent for materials such as glass, precious stones and metal. [0003] Iron oxide can be prepared by various methods, the more common ones are: ferrous sulfate produced by iron sheet and sulfuric acid is prepared by oxidation-reduction reaction. Accord...
