Abstract

The invention discloses a reactor and system for preparing potassium manganate. The reactor comprises a body, an ore pulp heating device and a stirring device, wherein a reaction space is limited in the body, an oxygen inlet, a waste oxygen outlet and a feeding port are formed in the top of the body at an interval, and a discharging port is formed in the upper-middle part of the body; the oxygen inlet is used for delivering oxygen or oxygen-enriched air to the reaction space, and the waste oxygen outlet is used for discharging residual oxygen and water vapor in the reaction space; the feeding port is used for delivering ore pulp into the reaction space, and the discharging port is used for discharging potassium manganate material liquid obtained after the oxidizing reaction of ore pulp in the reaction space; the ore pulp heating device is arranged in the body and is used for heating the ore pulp to 250-260 DEG C; the stirring device is arranged at the inner part of the body and is used for stirring the ore pulp. The reactor can efficiently prepare potassium manganate, has the advantages of simple structure, convenience in operation, cleanness and environmental friendliness, and is easy to realize industrialized mass production.

Description

technical field

[0001] The invention relates to the field of chemical industry, in particular to a reactor and a system for preparing potassium manganate. Background technique

[0002] At present, the preparation technology of industrial potassium permanganate is mainly divided into solid-phase oxidation method and liquid-phase oxidation method. Due to the limitations of the process itself and the MnO 2 Powder activity is poor, MnO 2 The oxidation reaction is not complete, resulting in MnO 2 Low conversion rate. In the process of preparing potassium permanganate by liquid phase oxidation, the preparation process of potassium manganate still has the problems of low conversion rate of manganese dioxide, low recovery rate of manganese and KOH, high energy consumption and serious environmental pollution.

[0003] Therefore, the preparation method and equipment of potassium manganate still need to be improved. Contents of the invention
