Description
Technical field
The present invention relates to a kind of multiple flow spiral winding tube type heat exchangers, in particular to a kind of to be disposed on same tube sheet
Concentric more than two circular ring shape stringings region and the multiply of thimble tube anti-vibration support is equipped in the changeover portion of tube bank
Flow spiral winding tube type heat exchanger.
Background technique
Currently, the shell-and-tube heat exchanger for a variety of media for heat exchange is mostly spiral winding tube type heat exchanger.In spiral winding
Heat exchanger tube is replaced by helix shape in space between pipe heat exchanger central tube and shell is entwined its main part, phase
The hand of spiral of adjacent two layers of spiral heat exchange tube on the contrary, this part is known as winding section, heat-exchanging tube bundle from winding section to tube sheet it
Between part be known as changeover portion.
There are two types of the common piping modes of multiple flow spiral winding tube type heat exchanger: one, using axial stringing and radial cloth
The mode (such as Fig. 1) that pipe combines arranges a kind of heat exchanger tube of process fluid on axial tube sheet, arranges other works on radial tube sheet
The heat exchanger tube of skill fluid, radial tube bank, can not be by heat exchanger tubes with biggish bending angle and axis due to closer to supervisor's plate off axis
It is attached to tube sheet, so that the partial region of axial tube sheet can not carry out stringing (such as Fig. 2).Two, one piece of axial tube sheet and more
The mode (such as Fig. 3) that a bobbin carriage is connected corresponds to bobbin carriage on axial tube sheet and several circular stringing regions is arranged (as schemed
4).Above two piping mode causes a part of region of tube sheet that can not carry out stringing, and the utilization rate of tube sheet is low.In addition, due to
Multiple inlet and outlets need to be divided into using radial tube sheet or several round cloth form of tubes, same process fluid, therefore, heat exchange
Device with process pipe when connecting, it is also necessary to which consider pipeline summarizes problem.
Tube bank changeover portion is for connecting tubesheet holes and winding section, when spiral winding tube type heat exchanger diameter is smaller, transition
Segment length is shorter, can not consider the support of changeover portion.As the enlargement of spiral winding tube type heat exchanger application is (usual
DN3000 is referred above to large heat exchanger), diameter is increasing, and required transition section length is also increasing, and changeover portion is prevented
It shakes more important.Also, the inlet and outlet of shell-side fluid are normally at the transition fragment position of spiral winding tube type heat exchanger, if mistake
Crossing section cannot be supported well, and the transversal flow of shell-side fluid is easier to cause the flutter failure of changeover portion heat exchanger tube.It crosses
Cross section heat exchanger tube common fixation methods be spiral wound tube type heat exchanger changeover portion restrain outmost turns steel band or steel plate
Wrapping is fixed, but the radial clearance between heat exchanger tube is eliminated or reduced to this method, hinders the uniform distribution of shell-side fluid.
And there are still biggish gaps between internal heat exchange tubes, not can solve the vibration problem of changeover portion heat exchanger tube.In addition,
Axial stretching can occur under cold and hot action of thermal difference for heat exchanger tube, to damage the outer surface of heat exchanger tube.
