Abstract

The invention discloses a centralized control recycling device and method for waste gas in a laboratory and belongs to the technical field of gas recycling. The centralized control recycling device comprises a recycling gas path and an electric control system, wherein the electric control system comprises a control module and a first pressure sensor; the recycling gas path comprises a buffering gas tank, a gas pump, a refilling pipeline and a gas storage bottle which are connected in sequence by pipelines; the buffering gas tank is further provided with a tail gas guide pipe for being connected with a tail gas outlet of an instrument; the first pressure sensor is arranged in the buffering gas tank; the control module is electrically connected with the gas pump and the first pressure sensor respectively. With the adoption of the recycling device and the recycling method, the aim of recycling tail gas after sulfur hexafluoride gas is measured in a gas detection laboratory can be realized; the recycling device and the recycling method have the characteristics of simple structure and convenience for operation.

Description

technical field [0001] The invention relates to a gas recovery device, in particular to a centralized control recovery device and recovery method for laboratory waste gas. Background technique [0002] Pure sulfur hexafluoride (SF 6 ) gas is a colorless, odorless, non-toxic, non-combustible gas at normal temperature and pressure. It has excellent insulating properties and arc extinguishing ability, and is an ideal insulating medium. At the same time, sulfur hexafluoride can exist in the air for more than 3200 years, and the greenhouse effect is CO 2 More than 23900 times. As a greenhouse gas, sulfur hexafluoride is one of the six gases prohibited by the Kyoto Protocol. With the rapid development of the power industry and the improvement of technical equipment, the construction of high-voltage transmission and distribution lines such as 500kV, 750kV, and 1000kV has accelerated, and a large number of sulfur hexafluoride circuit breakers and fully enclosed combined electrica...
