Material conveying method for horizontal reactor of potassium manganate

Abstract

The invention provides a material conveying method for a horizontal reactor of potassium manganate. The method is characterized in that: a multi-stage stirring reaction chamber is arranged inside the horizontal reactor; the reaction chamber is divided into relatively-independent reaction spaces by a deflection plate; and the materials are pushed to flow from the lower part of a previous chamber to the upper part of a next chamber, that is, the materials flow from the lower part of a first chamber to the upper part of a second chamber, and then flow from the lower part of the second chamber to the upper part of a third chamber and by analogy to an outlet of the reactor. The material conveying method provided by the invention effectively solves the problem that the potassium manganate product deposits at the bottom of the reaction materials and can not overflow to the next reaction chamber because the specific weight of the potassium manganate product is higher than that of the materials, increases the retention time of the materials in the reactor, and avoids the 'short-cut' of the materials, therefore, the reaction efficiency and the conversion rate are increased, the continuous operation and continuous reaction is realized, the volume of the reactor is reduced, the heat loss is reduced, the equipment investment and the running cost are reduced, and the floor area occupied by the equipment is reduced. The method can be applied to the reactions of high-grade and low-grade materials, and has a board material applicable range.

Description

technical field [0001] The invention relates to a material delivery method for the wet production of potassium manganate by a potassium manganate enterprise, in particular to a material delivery method for a horizontal reactor, and belongs to the field of chemical industry. Background technique [0002] Most enterprises in my country and the world use vertical reactors for the wet production of potassium manganate. The reaction kettle works under strong alkali, pure oxygen, high temperature and certain pressure. The cross section of the reaction kettle is cylindrical and made of 16Mn material. There is a stirring device in the reaction kettle, and it is equipped with an oxygen supply and pressurization system. The advantages of the vertical reactor are: easy operation and high conversion rate; but the disadvantages are: continuous operation cannot be realized, production efficiency is low, large investment, and large floor area.
