[0002] The dissolution reactor is a common equipment for chemical production or raw material mixing, and is often used in petrochemical, fine chemical, biochemical, and pharmaceutical chemical industries. It realizes the forced uniform mixing of liquid and solid media in the reactor body, and at the same time realizes the heat transfer, mass transfer and other processes of the medium. The existing reactor usually has only one stirring device in the reactor, and the solid medium and liquid medium in the reactor body cannot be mixed evenly by a single stirring device. At the same time, the contact area between the cooling pipe in the reactor body and the reaction medium is small, resulting in poor heat exchange effect of the medium. Ultimately, it is impossible to achieve rapid and uniform mixing of the reactants, resulting in failure to dissolve quickly and poor reaction effect. Therefore, it is necessary to design a reactor for material dissolution to overcome the above difficulties. Summary of the invention
