Abstract

The invention discloses an SF6 waste gas continuous recovery method and a recovery device, belongs to the technical field of SF6 gas recovery, and solves the problem of how to continuously recover an on-site SF6 waste gas. A gas path is connected to the front end of a compressor from the front end of a built-in recovery bottle of the SF6 waste gas recovery device, and a second pressure detection unit is connected into the gas path; and a gas path is connected to the front end of the built-in recovery bottle to a gas outlet connector, the gas outlet connector is connected with an expansion adapter, the other side of the expansion adapter is provided with a plurality of gas path connectors, each connector can be connected with an external recovery steel cylinder for continuous gas recovery, and in addition, if the waste gas recovered on site is too much, a proper recovery steel cylinder can be carried according to requirements. Whether expansion needs to be carried out or not is flexibly judged according to field requirements, if the recovery capacity needs to be expanded, a steel cylinder with the corresponding volume can be carried according to the field recovery gas volume, the recovery device is connected through the expansion part, the upper limit of the recovery gas volume of the recovery device is expanded, and external vacuumizing is not needed.

Description

technical field [0001] The invention belongs to the technical field of SF6 gas recovery, and relates to a continuous recovery method and recovery device for SF6 waste gas. Background technique [0002] Sulfur hexafluoride gas is currently the best insulation and arc extinguishing medium in the world, and is widely used in electrical equipment in the field of high voltage and ultra-high voltage. However, the greenhouse effect of SF6 gas is more than 20,000 times that of carbon dioxide, and it can exist stably in the air for more than 3,200 years. It is one of the six emission-restricted greenhouse gases pointed out in the "Kyoto Protocol", and has been listed as one of the top 10 global pollutants. [0003] Therefore, when using the SF6 detector on the SF6 site, it is necessary to recycle the SF6 waste gas in the detection instrument to reduce the pollution caused by the SF6 waste gas to the environment, but the gas storage tank in the existing SF6 waste gas recovery device ...
