Description of the drawings
Fig. 1 is the structural schematic diagram of reboiler in propane production line in embodiment；
Fig. 2 is the partial structural diagram of U-tube.
Specific implementation mode
The utility model is further described with reference to the accompanying drawings and examples.
As shown, the reboiler in the present embodiment in propane production line, including diversion cans 1, heater 2 and shell 3.
Partition board 4 is provided in the middle part of the diversion cans, the inner cavity of diversion cans is separated into oil inlet epicoele 5 and gone out by the partition board
Oily cavity of resorption 6 is provided with the inlet connector 7 being connected to oil inlet epicoele at the top of diversion cans, and the bottom of diversion cans is provided with and goes out
The oil returning pipe joint 8 of oily cavity of resorption connection.
The heater 2 includes the heating tube group 201 and be fixedly connected that the U-tube being arranged in parallel by several forms
Connecting plate 202 in heating tube group end；The connecting plate is connected by the oral area of bolt and diversion cans, the oil inlet of heating tube group
Mouth is connected to the oil inlet epicoele of diversion cans, and the oil discharge outlet of heating tube group is connected to the fuel-displaced cavity of resorption of diversion cans.
The U-tube is bellows.
The heating tube group 201 is made of at least two sections along the sequentially connected unit pipeline section in heater length direction, this reality
It is specially two sections to apply unit pipeline section in example.Buttcover plate 9 is fixedly welded on the end of the unit pipeline section, on adjacent cells pipeline section
Buttcover plate be bolted.
The shell 3 is connect by bolt with the connecting plate 202 on heater, and the shell is also by least two sections along shell
