Waste hydrogen energy-saving emission-reduction recycling device of oil product hydrogenation device

The utility model relates to a waste hydrogen energy-saving emission-reduction recycling device of an oil product hydrogenation device, which comprises a hydrogenation device provided with a waste hydrogen outlet pipe, and further comprises a compressor and a pressure swing adsorption device, one end of the waste hydrogen outlet pipe far away from the hydrogenation device is communicated with an inlet of the compressor, and the other end of the waste hydrogen outlet pipe is communicated with the pressure swing adsorption device. An outlet of the compressor is connected with an inlet of the pressure swing adsorption device through a gas pipeline. According to the utility model, waste hydrogen is conveyed into the pressure swing adsorption device through the waste hydrogen outlet pipe and the compressor, so that the waste hydrogen of the hydrogenation device can be effectively recovered, and the recovered waste hydrogen can be reused, thereby being beneficial to reducing the cost of hydrogenation reaction and r
