Device and method for measuring content of carbonate in sodium fluoride

Abstract

The invention relates to the field of detection of the content of carbonic acid in sodium fluoride, in particular to a device and method for measuring the content of carbonate in sodium fluoride. The device comprises a reaction tank, the reaction tank is provided with a feed port for placing reaction raw materials and an air inlet for continuously feeding air, and the upper end of the reaction tank is provided with a pressure regulating pipe; an absorption tower is arranged at the upper end of the right side of the reaction tank, an electromagnetic valve is slidably arranged in the pressure regulating pipe, and a buffer balloon is hermetically connected to the upper end of the pressure regulating pipe. The device has the beneficial effects that the electromagnetic valve which is provided with the piston ring and is mounted in the sliding manner is arranged in the reaction device, so that pressure adjustment is realized through sliding of the electromagnetic valve, air flow quickly flows to the absorption tower, and the pressure difference between the buffer inner cavity and the reaction inner cavity is matched with control of the electromagnetic valve on the valve, internal circulation of air flow is realized, so that carbon dioxide is fully absorbed after multiple times of cyclic absorption, and the detection precision is further improved.

Description

technical field [0001] The invention relates to the technical field of carbonate detection in sodium fluoride, in particular to a device and method for determining the content of carbonate in sodium fluoride. Background technique [0002] Sodium fluoride usually contains more carbonate impurities after production. In order to measure the content of carbonic acid in sodium fluoride, it is usually carried out by adding acid solution to produce carbon dioxide. [0003] However, in the actual detection process, due to the carbon dioxide contained in the reaction vessel and the air, the detection accuracy will be seriously affected. At the same time, during the absorption process through the soda solution, due to the fast flow rate of the air flow, it is usually impossible to achieve complete absorption, thereby further increasing detection error. [0004] Therefore, a device and a method for measuring the content of carbonate in sodium fluoride are provided to solve the problem...
