Novel alkaline hydrolysis tank and novel heating device and method for rare earth production

Abstract

The invention discloses a novel alkaline hydrolysis tank and a novel heating device and method for rare earth production. The novel alkaline hydrolysis tank for rare earth production comprises an alkaline hydrolysis tank body which is wrapped with a ceramic heating element set, and the inner surface of the ceramic heating element set is attached to the outer wall of the alkaline hydrolysis tank body. The novel heating device for rare earth production comprises the alkaline hydrolysis tank body, a temperature control device, a pressure regulating device, a power source and a temperature measuring element. The novel heating method for rare earth production includes the following steps of (1) device preparation and connection and (2) temperature control program setting for heating. The novel alkaline hydrolysis tank and the novel heating device and method for rare earth production have the advantages that energy is saved, emission is reduced, comprehensive utilization of resources is achieved, economic benefits are good, and a good development and application prospect can be achieved.

Description

technical field [0001] The invention relates to a novel alkaline hydrolysis tank, a novel heating device and a heating method, in particular to a novel alkali hydrolysis tank, a novel heating device and a heating method for rare earth production. Background technique [0002] Alkaline chlorination of rare earth concentrates requires high decomposition rate and yield, while the traditional eddy current electric heating alkaline hydrolysis tank generally directly raises the reaction temperature to 150 degrees, which is particularly easy to cause paste or overflow at high temperature, and the product It is easy to change the price, and the slurry will seriously corrode the alkaline hydrolysis tank after the pot is pasted or overflowed. In addition, the traditional alkaline hydrolysis tank generally uses a one-layer stirring paddle. As the reaction temperature rises and the water evaporates, the slurry becomes thicker and thicker, which is easy to cause a paste pot. Contents o...
