The invention provides a detecting and absorbing device applied to
sulfur hexafluoride gas. The detecting and absorbing device is characterized in that a filter membrane arranged in a sealed tank body is a
glass fiber membrane, an
injector is connected with a common opening of a multi-way valve, a first
branch opening of the multi-way valve is communicated with an atomizer arranged in the sealed tank body through a liquid outlet
pipe, a second
branch opening of the multi-way valve is connected with the bottom of a detection tank, and a third
branch opening of the multi-way valve is a
carbon tetrachloride liquid inlet; a liquid level
control switch is arranged on a lateral wall of the upper end of the detection tank, an
infrared light source and an
infrared detector are oppositely arranged on the two sides of the detection tank respectively, and the top end of the detection tank is communicated with the bottom close to an air inlet of one side of the sealed tank body; the upper end of an absorbing tank is communicated with an air exhausting pipeline, a middle lower part of the absorbing tank is communicated with an air outlet of the sealed tank body through an air inlet
pipe provided with an ejector and an
electromagnetic valve, the outer input end of the ejector is communicated with the bottom of the absorbing tank through a liquid
circulating pump, and an inlet of a six-way valve is connected with an
injection pump; the
buffer tank is in serial connection with an air
circulating pump to be communicated with the air exhausting pipeline and the air inlet pipeline respectively, and a
fluorine ion sensor is arranged at the lower end in the absorbing tank.
