Detection and absorption device for SF6

Abstract

The invention provides a detection and absorption device for SF6. SF6 enters a closed tank of a mineral oil content measuring unit and filtered by a filter membrane, and a product is discharged into an SF6 acidic material absorption unit; a motor controls an injector to inject a CCl4 solution into the closed tank, CCl4 mist spray is formed by a first atomizer, mineral oil in the filter membrane is eluted, an eluent is discharged into a detection tank, elution is stopped when content change of the mineral oil in the eluent tends to be stable, and a liquid in the detection tank is subjected to volume fixing with the CCl4 solution; after the volume fixing is finished, detection work is completed with an infrared light source and an infrared detector; for SF6 discharged from the closed tank, SF6 acidic materials make sufficient contact with an NaOH solution and are absorbed completely by aid of an NaOH solution circulating module and a gas circulating module assisted by a second atomizer and a gas spray nozzle. The detection and absorption device can measure the content of the mineral oil in SF6 accurately and sufficiently absorb the acidic materials in SF6 and is excellent in working performance.

Description

technical field [0001] The invention provides a detection and absorption device for sulfur hexafluoride gas, which belongs to the technical field of power system detection technical background [0002] Whether it is industrial sulfur hexafluoride gas or sulfur hexafluoride gas in operation, the mineral oil content is a key indicator of its quality control, which is crucial to improving the safety and service life of electrical equipment. Quantification of mineral oil content in sulfur hexafluoride gas needs to be measured with the help of carbon tetrachloride standard solution prepared from mineral oil. Due to the strong volatility of carbon tetrachloride and the large number of prepared solutions, the parallel test error is relatively large. Not very accurate. At present, there are mainly two types of determination of mineral oil content in sulfur hexafluoride gas: one is to use carbon tetrachloride solution to absorb mineral oil in sulfur hexafluoride gas, and then use in...

The utility model has the characteristics of convenient operation, high absorption efficiency, and less solution consumption. The disadvantages are: 1. There is no real-time detection function of the absorption process, so it is difficult to ensure the complete absorption of acidic substances in sulfur hexafluoride gas and accurate detection of the measured six The volume of sulfur fluoride gas; 2) only rely on sulfur hexafluoride gas to enter from the bottom of the gas absorption pool and absorb it by NaOH solution, the absorption efficiency needs to be further improved and increased
