Automatic electrolyte sampling device of medium-temperature electrolytic fluorine production equipment

Abstract

The invention belongs to the technical field of electrolytic fluorine production, and particularly relates to an automatic electrolyte sampling device of medium-temperature electrolytic fluorine production equipment, the device comprises a sampling pipe, a connecting flange, a pneumatic valve A, a pneumatic valve B, a sampling bottle, a safety bottle, a vacuum machine, an automatic control system and nitrogen. By means of the device, operators can operate remotely, the possibility that the operators make contact with poisonous and harmful substances such as hydrogen fluoride and electrolyte is eradicated, and the safety capacity of the system is improved. Sampling can be completed without cutting off current, the stability of continuous operation of the electrolytic cell is improved, and the continuous operation performance of the electrolytic cell is improved. The electrolyte is not contacted with metal and air in the sampling process, so that the accuracy of the sample is improved.

Description

technical field [0001] The invention belongs to the technical field of electrolytic fluorine production, and in particular relates to an electrolyte automatic sampling device for medium-temperature electrolytic fluorine production equipment. Background technique [0002] In the field of electrolytic fluorine production, the main technique of electrolyte sampling is manual sampling. In production practice, conventional sampling methods include full distribution sampling and local sampling. [0003] In the above methods, the sampling port of the electrolyzer needs to be opened, causing the poisonous and harmful hydrogen fluoride and hydrogen gas inside the electrolyzer to leak into the environment; among them, due to the flammable and explosive characteristics of hydrogen, it is generally necessary to stop the operation of the electrolyzer for sampling operation. Moreover, there are certain potential safety hazards for personnel to come into contact with toxic and harmful sub...

Problems solved by technology

[0003] In the above methods, it is necessary to open the sampling port of the electrolytic cell, causing the poisonous and harmful hydrogen fluoride and hydrogen gas inside the electrolytic cell to leak into the environment; due to the flammable and explosive characteristics of hydrogen, it is generally necessary to stop the operation of the electrolytic cell for sampling operations

And there are certain potential safety hazards for personnel to come into contact with toxic and harmful substances such as electrolytes, hydrogen fluoride, and hydrogen.

After sampling, when scraping the sample, due to the characteristics of the metal (sampling rod) reacting with the electrolyte surface, the adsorption layer is thin, and the electrolyte itself absorbs water, etc., there will be a certain distortion in the sample
