Production method and production device of high-purity fluorine gas and fluorine containing mixed gas

Abstract

The invention discloses a production method and a production device of high-purity fluorine gas and fluorine containing mixed gas. The production device mainly consists of an anhydrous hydrogen fluoride steel cylinder, an electrolytic cell, a solid residue catcher, a cooling acid remover, an acid adsorption tower, a buffer tank, a middle compressor, a purifier, a particulate filter, a product storage tank, a filling compressor, a finished product container, and a hydrogen gas washing tower. The production method comprises the following steps that dry nitrogen gas fills the anhydrous hydrogen fluoride steel cylinder; liquid anhydrous hydrogen fluoride is added into the electrolytic cell; an electrolytic reaction is performed to produce fluorine gas; and orderly the fluorine gas enters the solid residue catcher for removing particulate materials, enters the cooling acid remover for removing HF, enters the acid adsorption tower for removing hydrogen fluoride gas, enters the buffer tank, is compressed by the middle compressor and sent into the purifier, enters the particulate filter for removing adsorption agent particles, enters the product storage tank and fills the product steel cylinder. The production method and production device provided by the invention have the beneficial effects that the fluorine gas purity is high, the production process is simple, the operation performance is safe and reliable, the system runs stably, and continuous production and linkage self-control can be realized.

Description

technical field [0001] The invention relates to the technical field of special gas production, in particular to a production method and production device for high-purity fluorine gas and fluorine-containing mixed gas with simple production process, safe and reliable operation performance, stable system operation, continuous production and chain automatic control. . Background technique [0002] With the development of emerging technologies, there are many types of special gas demand, the technical level of domestic enterprises is uneven, the market supply and demand, in terms of quantity, the supply exceeds demand, and the production capacity is excess; 36% of production capacity; supply shortage, relying on imports. Practitioners in the production of special gases can only meet the quality requirements of special gases by relying on technological progress. [0003] High-purity fluorine gas (F2) is an important raw material in the field of fine chemicals. It is widely use...
