Recycling device for terbium oxide production waste gas

The utility model discloses a recovery treatment device for terbium oxide production waste gas, which comprises a base plate, a filtering mechanism and a purifying mechanism, and water in a water bucket sprays injected gas, so that the purifying and filtering effects can be further improved; under the action of two concentration detectors, the concentration of gas in the purification box can be detected, so that the purification and filtration effect and quality can be ensured, an exhaust channel is formed in one side of the purification box and is externally connected with an exhaust pipeline, the purified and filtered gas can be exhausted, and the purification and filtration efficiency is improved. By arranging the filter cavity, solid particles in gas can be intercepted, so that the actual use effect can be ensured; the gas injection pipe is externally connected with the gas inlet pipe, the purpose of injecting waste gas can be achieved, the injected waste gas can be preliminarily purified and filtered by
