AI Technical Summary

Technical Problem

The existing preparation method of cuprous iodide is complicated to operate, has a long reaction time, a low product yield, and produces a lot of three wastes, making it unsuitable for industrial production. In addition, the utilization rate of iodine resources is low, resulting in a waste of resources.

Method used

The iodine element in the aromatization stock solution generated during the production of 3,5-dimethylphenol is used as raw material. Sodium iodide is generated through a reaction in a No. 1 stirring tank, and then reacts with a copper sulfate solution to generate cuprous iodide. A pure product is obtained after filtration, washing, and drying, and the unseparated iodine element is recovered to improve iodine utilization.

Benefits of technology

The method realizes efficient recovery and utilization of iodine resources, produces high-purity cuprous iodide, reduces production costs and brings economic benefits.

Abstract

The utility model belongs to the technical field of chemical reaction devices, and particularly relates to a production device of cuprous iodide. The production device of the cuprous iodide comprises a raw material tank, a first stirring tank, a reaction tank, a filtering and washing tower and drying equipment which are connected in sequence, the raw material tank comprises an aromatization stock solution storage tank, a sodium carbonate solution storage tank and a sodium sulfite storage tank; the aromatization stock solution storage tank, the sodium carbonate solution storage tank and the sodium sulfite storage tank are respectively communicated with the first stirring tank; and the reaction tank is also communicated with a copper sulfate solution storage tank. The utility model provides a production device of cuprous iodide, which aims at solving the problems of resource waste and difficulty in subsequent garbage treatment due to the fact that elemental iodine contained in an aromatization stock solution is treated as garbage in the prior art, takes the aromatization stock solution as a raw material, fully utilizes the elemental iodine in the aromatization stock solution and generates more expensive cuprous iodide.
