Storage tank tail gas oil gas recovery treatment device

The utility model discloses a storage tank tail gas oil gas recovery processing device which comprises a bottom plate, a lifting assembly is arranged on the upper side of the bottom plate, the lifting assembly is used for adjusting the height of a conical hopper, a first pipeline and a second pipeline are arranged in the lower side wall of the conical hopper in a penetrating mode, and an oil gas condensation recovery assembly is arranged on the upper side of the bottom plate. And the oil gas condensation recovery assembly is communicated with the pipeline II. The conical hopper is moved downwards through the lifting assembly, the conical hopper is used for sealing the oil filling port of the oil storage tank, the first pipeline is communicated with an external oil filling pipe or the first pipeline is sealed, then oil gas in the oil storage tank can be pumped out through the oil gas condensation recovery assembly and liquefied for storage, and therefore the situation that the oil gas is directly discharged in
