Abstract

The invention discloses a device for measuring the content of fluorine in a fluorine-containing mixed gas, which comprises a base, a protective box is fixed on the upper end of the base, a cavity is arranged in the protective box, and a protective box is installed in the bottom of the cavity , the first chromatographic column, the second chromatographic column and the third chromatographic column are equidistantly arranged in the protective box, and the first chromatographic column, the second chromatographic column and the third chromatographic column are connected to each other, and the cavity Both sides are hinged with bearing plates; a method for measuring fluorine gas content in fluorine-containing mixed gas, comprising the following steps: pushing the entire car body to a measurement position in a production workshop in advance, and using a wire winder to lower the bearing plate. The invention can not only quickly detect the content of fluorine gas, but also can detect the mixed gas at different positions according to the needs. At the same time, it is convenient to move, has fast detection time, high efficiency, does not affect the normal production, and reduces labor costs and production costs. , Strong practicability.

Description

technical field [0001] The invention belongs to the technical field of forming molds, and in particular relates to a device for measuring the fluorine content in a fluorine-containing mixed gas. Background technique [0002] Fluorine gas is a very corrosive pale yellow diatomic gas with a strong pungent smell and a strong oxidant. At room temperature, it can combine with almost all elements and generate a lot of heat energy. [0003] At present, medium-temperature electrolytic fluorine production is the main development direction of domestic and foreign electrolytic fluorine production processes. The fluorine gas produced contains oxygen, nitrogen, carbon tetrafluoride, hydrogen fluoride and other impurity gases. Fluorine gas is also the raw material for the industrial production of sulfur hexafluoride. The control of the concentration of fluorine gas in the process of producing sulfur hexafluoride plays a guiding role in the production of the subsequent system. Therefore, t...
