Including a pipe body

The utility model relates to an including a pipe body, carries out the intensive mixing with weary gas behind the pneumatic motor inflation and liquid cold working medium in the working process, retrieves the energy of weary gas, and liquid medium after mixing lets in pressure boost in the working medium pump, and the working medium of discharging afterwards pump continues the absorbed energy, circulates next time. The beneficial effects of the utility model reside in that improve the connected mode for expander, space backheat, working medium pump with the arrangement form of expander, regenerator, condenser, working medium series connection of pumps among the organic rankine cycle of tradition to it is coaxial with the rotor of working medium pump with the expander, so can retrieve wearygas energy and promote the cycle efficiency, make arranging of evaporimeter, condenser freer, the degree of freedom that the operating mode was adjusted is more, reduces part quantity to the compactdegree of part has been in
