Gas producer

The utility model provides a gas producer, and relates to the technical field of gas producers, the gas producer comprises a gas pipeline, a diffusion pipeline and a bell jar valve, the bell jar valve is used for discharging gas in the gas pipeline into the diffusion pipeline, a middle pipeline communicating the gas pipeline with the diffusing pipeline is arranged between the gas pipeline and the diffusing pipeline, gas in the gas pipeline is used for being discharged into the diffusing pipeline through the middle pipeline, and a collecting pipeline communicating with the diffusing pipeline is arranged below the diffusing pipeline. Coal tar condensed from the diffusing pipeline flows into the collecting pipeline under the action of gravity. Compared with the prior art, the coal gas producer disclosed by the utility model has the advantages that coal tar in the diffusion period of the coal gas producer is effectively collected, the coal tar is prevented from entering the bell jar valve, and the bell jar valve
