Abstract

The invention relates to the field of tail gas recovery, in particular to an analysis tail gas recovery device which comprises a tail gas gathering unit and a negative pressure extraction unit, the tail gas gathering unit communicates with a gas analyzer, a first pipeline is arranged at the end, away from the gas analyzer, of the tail gas gathering unit, and one end of the negative pressure extraction unit is connected to the first pipeline; the other end of the analysis tail gas recovery device is connected with the industrial treatment device; the analysis tail gas recovery device further comprises an atmosphere emptying unit and a pressure supplementing unit; the atmosphere emptying unit is used for emptying redundant pressure in the first pipeline, and the atmosphere emptying unit is located at the end, away from the tail gas gathering unit, of the first pipeline and communicates with the first pipeline; the pressure supplementing unit is used for maintaining the pressure in the first pipeline to be stable and comprises a pressure stabilizing supplementing piece and a pressure regulator, and the pressure regulator is located between the pressure stabilizing supplementing piece and the first pipeline and communicates with the pressure stabilizing supplementing piece and the first pipeline. According to the invention, normal pressure and stable pressure states can be kept in the first pipeline.

Description

technical field [0001] The present application relates to the field of tail gas recovery, in particular to an analytical tail gas recovery device. Background technique [0002] In industrial production, for normal and safe production, various industrial gases must be analyzed. During analysis, gas analyzers are often used to analyze gases. Gases need to be discharged at atmospheric pressure through a gas analyzer, but toxic and harmful gases cannot be directly Atmospheric emission, the exhaust gas must be recovered at atmospheric pressure and constant pressure by the analytical exhaust gas recovery device and transported to the industrial processing device (the gas enters the analytical exhaust gas recovery device after passing through the gas analyzer, and the gas entering the analytical exhaust gas recovery device is called tail gas) , for harmless treatment or recycling. [0003] The exhaust gas enters the industrial processing device through the analytical exhaust gas r...
