This invention relates to the field of energy recycling, specifically to a hydraulic turbine-based oil pipeline residual pressure recovery and power generation system. The system includes a high-pressure oil pipeline, a low-pressure oil pipeline, a hydraulic turbine power generation unit, a working support unit, and an intelligent control unit. The hydraulic turbine power generation unit forms a parallel pipeline structure with the bypass protection submodule of the working support unit via a power generation branch. The upstream end of the parallel pipeline structure is connected to the high-pressure oil pipeline, and the downstream end is connected to the low-pressure oil pipeline. The intelligent control unit and the working support unit have bidirectional communication connections, forming a safe oil transportation and residual pressure recovery structure with switchable operating modes. This invention, through the parallel layout of hydraulic turbine power generation and main pipeline pressure reducing valve, changes the traditional passive energy consumption mode. Based on the actual pressure and flow requirements of the pipeline operation, it can rationally realize the recovery and utilization of excess pressure energy.

This utility model relates to the field of oil transportation pipelines, specifically to a high-tightness oil transportation pipeline connection assembly. It includes two supports placed at both ends of the oil pipeline, with multiple inclined support rods rotatably connected to the supports, the ends of which push the adjacent flanges outwards. The advantages of this utility model compared to existing technologies are: at the connection point of adjacent oil pipeline fittings, this assembly provides two tightly fixed flanges on both sides, each with a set of rotatable support rods. The ends of the support rods press tightly against the inner side of the flanges, and the outward expansion of the oil inside the pipe causes the support rods to move closer together. The force carried by this force further tightens the two flanges together, preventing the pipeline from being damaged or leaking due to excessive oil pressure at the connection point.

This disclosure relates to a liquefied oil transportation pipeline and a coal liquefaction system. The transportation pipeline includes a main pipeline, a diversion valve assembly, and a slag discharge assembly. The diversion valve assembly is connected to the main pipeline to divide the main pipeline into multiple independently controllable diversion pipelines. Each diversion pipeline includes a delivery pump. Multiple slag discharge assemblies are provided, each corresponding to and connected to a diversion pipeline, and located between the delivery pump and the diversion valve assembly. These assemblies are used to dynamically recover coking impurities in the diversion pipelines. This liquefied oil transportation pipeline, by dividing the main pipeline into multiple independently controllable diversion pipelines through the diversion valve assembly, avoids situations where one delivery pump in the same pipeline has an excessive flow rate while another has an insufficient flow rate during the transportation of solid-containing liquefied oil. The slag discharge assembly is also provided in each diversion pipeline, which can dynamically recover coking impurities generated in the diversion pipelines, preventing coking impurities from entering the delivery pumps through the diversion pipelines and causing damage.
