[0001] The utility model relates to the technical field of tail gas recovery and treatment, in particular to a high-efficiency tail gas analysis and treatment system. Background Art

[0002] In order to ensure normal and safe production in industrial production, various industrial gases must be analyzed. During the analysis, a gas analyzer is often used to analyze the gas. The gas needs to be discharged at normal pressure through the gas analyzer, but toxic and harmful gases cannot be discharged directly into the atmosphere. An analytical tail gas recovery device must be used to recover the tail gas at normal pressure and constant pressure and transport it to an industrial processing device (the gas enters the analytical tail gas recovery device after passing through the gas analyzer, and the gas entering the analytical tail gas recovery device is called tail gas) for harmless treatment or recycling.

[0003] In the prior art, patent number: CN219424040U provides a metal tail gas recovery device, which belongs to the field of tail gas recovery technology. The metal tail gas recovery device includes a refrigeration structure, a spray structure and a dust collection structure. Among them, the refrigeration pump is arranged in the refrigeration chamber 1, the cold air output pipe of the refrigeration pump passes through the top plate of the refrigeration chamber 1 and is connected to the refrigeration chamber 2, the motor is arranged in the refrigeration chamber 1, the cold fan is arranged in the refrigeration chamber 2, and the output end of the motor passes through the top of the refrigeration chamber 1 and is connected to the cold fan. Spray pipes are arranged on the top of the spray chamber 1, the spray chamber 2 and the spray chamber 3, and a sewage pipe is arranged at the sewage outlet. Dust collecting pipes are arranged on the top of the dust collecting chamber 1 and the dust collecting chamber 2, and the air outlet of the dust collecting pipe is arranged with an exhaust fan. Through the arrangement of this structure, the problem that a large amount of large particles and high-temperature gases mixed together are usually produced in the tail gas during the metal smelting process, and such particles often cause damage to the vacuum equipment when vacuuming.

[0004] Although the above-mentioned tail gas recovery device can process and recover tail gas by spraying, it still has the following shortcomings in practical applications: the spraying treatment of tail gas requires a large amount of treatment liquid, and these treatment liquids are directly discharged, and new treatment liquids need to be continuously added, resulting in a waste of resources.
