The utility model can be realized by following technique measures: two thermal source muitishell adverse current acceleration type shell-and-tube heat exchangers, comprise housing, housing one side is provided with internal tube plate and outer tube plate, bobbin carriage is connected the outer tube plate outside and inside is provided with dividing plate, the housing opposite side is provided with end cap, be provided with the composite heat-exchange pipe in the housing, described composite heat-exchange pipe is made up of outer tube and the inner sleeve that is installed in the outer tube tube chamber, and the external diameter of inner sleeve is less than the aperture of outer tube; Vertical adverse current speedup deflector is set in the housing, and bobbin carriage is provided with interface tube I and interface tube II, and the upper and lower of housing is respectively equipped with interface tube III and interface tube IV between outer tube plate and the internal tube plate, and interface tube V and interface tube VI are set on housing.
Enclosure interior is at least double-shell, a vertical adverse current speedup deflector is set between every double-shell, shell side of every increase, vertical adverse current speedup deflector of corresponding increase in the housing makes the extratubal fluid flow process number of formation identical with tube fluid flow process number and direction is opposite.
In the extratubal fluid runner of described housing and vertically adverse current speedup deflector formation at least one horizontal speedup disturbance deflector is set; Laterally speedup disturbance deflector shape is identical with extratubal fluid cross section of fluid channel shape, and laterally speedup deflector one end leaves the passage breach, and has the pore that is used to support heat exchanger tube on deflector plate face.
Described composite heat-exchange pipe is the straight pipe type composite heat-exchange pipe that both sides are equipped with internal tube plate and outer tube plate, and outer tube is applied on two internal tube plates, and inner sleeve is applied on two outer tube plates and respectively and is communicated with bobbin carriage and end cap.
Described composite heat-exchange Guan Weiyi side is provided with the U type cast composite heat-exchange pipe of internal tube plate and outer tube plate.
Described composite heat-exchange pipe is the combination of U type cast composite heat-exchange pipe and straight pipe type composite heat-exchange pipe.
Annular space looping medium channel between the outer wall of inner sleeve and the inwall of outer tube, the tube chamber of inner sleeve constitutes the central medium passage, and the inwall of housing and the outer wall of outer tube constitute medium channel.
The technique effect that the utility model produces is as follows:
The two thermal source muitishell adverse current acceleration type shell-and-tube heat exchangers of the utility model, its heat exchanger tube is made of jointly outer tube and inner sleeve, three medium channels have been formed, can realize three kinds of synchronous heat exchange of medium: by the vertical adverse current speedup deflector that is provided with in the housing one way shell side is divided into muitishell simultaneously, can improve the flow velocity of shell fluid and make its longitudinally with outer tube and the formed circular passage of inner sleeve in fluid form adverse current, avoid occurring the height of shell-side fluid and circular passage inner fluid, low-temperature space forms the situation of striding the warm area heat exchange, has reduced the heat transfer temperature difference loss of two kinds of fluids; The flow velocity and the disturbance of shell fluid have been increased by the horizontal speedup disturbance deflector that is provided with in the housing.The utility model can be realized medium and the synchronous and reverse flow heat exchange of two media in addition in the annular medium channel, when reaching two kinds of synchronous compound utilizations of thermal source, reduces heat transfer temperature loss between fluid, improves heat exchange efficiency.
