Experimental device for preparation and post-treatment of anhydrous zinc acetate

Abstract

The invention discloses an experimental device for preparation and post-treatment of anhydrous zinc acetate. The experimental device comprises a reaction device and a post-treatment device which are respectively provided with a stirring mechanism, the reaction device comprises a reaction cavity, a liquid inlet and a solid feeding hole are formed in the upper part of the reaction cavity, a discharge hole is formed in the bottom, and a jacket I is arranged outside the reaction cavity; the post-treatment device comprises a post-treatment cavity, a condensing device, a heat exchanger and a collector which are connected in sequence; and a feeding hole communicated with the discharging hole through a pipeline is formed in the upper part of the post-treatment cavity, a material discharging hole and a liquid discharging hole are formed in the bottom of the post-treatment cavity, a filtering mechanism is arranged at the bottom in the post-treatment cavity, and a jacket II is arranged outside the post-treatment cavity. Solid-liquid separation is achieved through the pipeline and the device, solid-liquid separation can be achieved without transferring feed liquid out during feed liquid aftertreatment, separated solids can be directly dried, the whole process is operated in a closed mode, the feed liquid does not need to be transferred out, operation is easy, and working efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of chemical equipment, and in particular relates to an experimental device for the preparation and post-treatment of anhydrous zinc acetate. Background technique [0002] Depleted zinc acetate dihydrate is an important nuclear power additive for adding zinc to nuclear power. Its upstream product is depleted anhydrous zinc acetate. The preparation of depleted anhydrous zinc acetate requires depleted zinc oxide as a raw material. The preparation reaction is A multi-step solid-liquid reaction, the solid product needs to be filtered after the reaction is completed, and then dried to obtain anhydrous zinc acetate product. The whole test operation process is relatively complicated. Contents of the invention [0003] The present invention proposes in order to overcome the shortcoming that exists in the prior art, and its purpose is to provide a kind of experimental device of anhydrous zinc acetate preparation and...
