Simulation greenhouse gas generation device

The present invention discloses a simulation greenhouse gas generation device. The simulation greenhouse gas generation device comprises a pipeline arranged in a vertical direction; an area in the pipeline is divided into a greenhouse gas mixing function section, a greenhouse gas flow stabilization function section and a greenhouse gas test function section which are distributed from bottom to top; a plurality of corrugated plate fillers are installed in the greenhouse gas mixing function section, wherein the corrugated plate fillers are arranged in a staggered manner; three installation holes, located below the corrugated plate fillers, are formed at the side wall of the pipeline; each of the outlets of a first gas incoming valve, a second gas incoming valve and a third gas incoming valve is communicated with one end of a corresponding gas pre-distribution pipe; a plurality of gas distribution holes are formed at the upper wall of pipe sections of the gas pre-distribution pipes, wherein the pipe sections of
