Abstract

The invention discloses an absorption device for acidic substances in sulfur hexafluoride gas and hydrolyzable fluoride, which comprises a gas absorption pool and an absorption liquid. The absorption liquid is arranged inside the gas absorption pool. The gas absorption pool is a vertical The long and thin structure placed vertically, the absorption liquid is a certain concentration of sodium hydroxide solution; the control pipeline of the gas absorption pool is provided with a number of electromagnetic valves that can be opened and closed arbitrarily; the bottom of the gas absorption pool is connected to There is an air inlet, and a pressure reducing valve and a steady flow valve are sequentially connected between the air inlet and the bottom of the gas absorption pool; the bottom of the gas absorption pool is also connected with an automatic sampler and a liquid outlet ; The top of the gas absorption pool is connected with an exhaust port; the top of the gas absorption pool is provided with a pressure sensor. The invention also proposes a method for absorbing acidic substances and hydrolyzable fluorides in sulfur hexafluoride gas, which has the characteristics of convenient operation, high absorption efficiency and less solution consumption.

Description

technical field [0001] The invention relates to a device and method for absorbing acidic substances and hydrolyzable fluorides in sulfur hexafluoride gas, belonging to the technical field of electric power equipment. Background technique [0002] At present, for the absorption of acidic substances and hydrolyzable fluorides in sulfur hexafluoride gas, a pure manual device is used under normal pressure. The test device is complicated, the absorption speed is slow, and the contact area between the gas and the absorption solution is limited. Although the absorption liquid content is large, However, it is not easy to absorb completely. Such an absorption method reduces the accuracy of detection of acidity and hydrolyzable fluoride content in sulfur hexafluoride gas. The parallel test error is large and the test takes a long time. With the acceleration of the UHV power grid construction process in the power industry, the rapid and accurate detection of the acidity of sulfur hexaf...
