Incinerator oxygen content detection device

The utility model relates to an incinerator oxygen content detection device which comprises an incinerator tail gas flue and an industrial oxygen meter, the incinerator tail gas flue is provided with a smoke exhaust fan, the input end of the industrial oxygen meter is communicated with an oxygen meter analysis chamber, and the oxygen meter analysis chamber is communicated with an air outlet of the smoke exhaust fan through an air inlet pipeline. And the oxygen meter analysis chamber is communicated with an air inlet of the smoke exhaust fan through an air outlet pipeline. The device has the advantages that the smoke exhaust fan is adopted to improve and stabilize the gas conveying pressure of the incinerator tail gas flue, and stable air pressure needed by an industrial oxygen meter is provided; moisture in the flue gas is removed through the condenser, and a heat preservation belt is wound outside to further enable the oxygen meter analysis chamber to keep a good dry environment; and dust particles in the fl
