Description
Technical field
This utility model relates to shell-and-tube heat exchanger technical field, changes particularly to a kind of bifilar stream mixed tube bundle shell-and-tube
Hot device.
Background technology
Heat exchanger is to regulate processing medium temperature and recovery waste heat thus realizes one of energy-saving and cost-reducing key equipment.Around pipe
Heat exchanger is a kind of special shell-and-tube heat exchanger, compared with general shell-and-tube heat exchanger, has heat transfer coefficient around heat exchange of heat pipe
Greatly, compact conformation, tube side fouling tendency be little, economic operating cost, take up room the advantage such as little, in the mistake of large-scale air segregation apparatus
Cooler and liquefier (liquid oxygen, liquid ammonia) are widely used, are also widely used in pharmacy, food, oil, chemical industry, smelting simultaneously
The fields such as gold, electric power, weaving and HVAC.
Existing wrap-round tubular heat exchanger mainly has the parts such as housing, core cylinder and helical bundle, and core cylinder is two ends welding
Being fixed on the closed cylinder of tube sheet, be positioned at the effect of heat exchanger center support helix pipe, this structure causes core cylinder part not
Participating in heat exchange, waste the space of heat exchanger, decrease heat exchange area, make heat exchanger the compactest, heat exchange efficiency has much room for improvement.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, this utility model provides a kind of bifilar stream mixed tube bundle shell-and-tube and changes
Hot device, replaces core cylinder with self-support type straight tube bundle, adds heat exchange area, tradition wound tube heat exchanger core cylinder part is occupied
Space is used, and improves heat exchanger heat exchange efficiency.
This utility model be the technical scheme is that a kind of bifilar stream mixed tube bundle shell-and-tube heat exchanger, including housing,
Tube sheet, flange, end socket, cylindrical shape dividing plate, serpentine pipe, spiral rib straight tube, normal straight tube, shell side inlet/outlet pipe, Helical Tube
Journey inlet/outlet pipe, straight tube tube side inlet/outlet pipe and hanging support.It is characterized in that: be made up of spiral rib straight tube and normal straight tube
Self-support type straight tube bundle, for replacing the core cylinder of traditional wound pipe heat exchanger, the two ends of straight tube bundle are by being fixedly welded on pipe
On plate；Described serpentine pipe is wrapped in outside straight tube bundle, and the winding direction of adjacent two layers serpentine pipe is contrary, and serpentine pipe two ends are by welding
It is fixed on tube sheet；Described end socket, cylindrical shape dividing plate form bobbin carriage with flange, and cylindrical shape dividing plate one end is welded in inside end socket,
The other end and the circular trough Butt sealing on tube sheet, and bobbin carriage is divided into two spaces, correspond respectively to straight tube tube side and spiral
Pipe tube side.
Described tube sheet is corresponding to processing a circular trough in the plane of bobbin carriage, for docking with cylindrical shape dividing plate.
Described normal straight tube and spiral rib straight tube all use larger-diameter tubing, can be selected for carbon steel pipe or rustless steel
Pipe, and described serpentine pipe uses the tubing of small diameter, can be selected for stainless steel tube or copper pipe.
Described self-support type straight tube bundle presses circular concentric stringing, and its internal layer arranges spiral ribs bar straight tube, and outermost layer is arranged general
Logical straight tube, forms self-supporting by spiral ribs bar between straight tube.
Described serpentine pipe is the most successively wrapped on self-support type straight tube bundle, serpentine pipe the most circumferentially
Interval 90 or 60 arranges 2～6mm thick metal isolating strips, and after the pipe end of serpentine pipe is the most swollen with the employing of tube sheet junction, weldering mode is solid
Fixed.
Described spiral rib pipe is at normal straight tube outer wall winding screw metal rib, and the height of rib is equal to tube pitch,
Rib two ends are fixed on straight tube by spot welding.
Compared with prior art, this utility model has the advantages that one is to instead of with self-support type straight tube bundle
The core cylinder of tradition wound tube heat exchanger, takes full advantage of the space shared by core cylinder part, adds heat exchange area, improve heat exchange
Efficiency；Two is self-support type straight tube bundle and helical bundle constitutes mixed tube bundle, makes heat exchanger structure more compact, and improves and change
The flowing space of hot device shell-side fluid；Three is bobbin carriage to be divided into two spaces, it is achieved thereby that tube side is bifilar with cylindrical shape dividing plate
Stream.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further illustrated.
The assembling process of bifilar stream mixed tube bundle shell-and-tube heat exchanger: first by spiral rib straight tube and normal straight tube by interior
Layer outer layers inserts side tube sheet the most one by one, the most again by root, straight tube is inserted opposite side tube sheet, then by the most swollen rear weldering
Mode all straight tubes are fixed with tube sheet, form self-support type straight tube bundle；Serpentine pipe is the most successively wrapped in from propping up
On support straight tube bundle, serpentine pipe arranges some parting beads between layers, and adjacent layer helical bundle is oppositely oriented, serpentine pipe pipe end and pipe
Plate uses the most swollen rear weldering mode to fix；Heat-exchanging tube bundle entirety is loaded housing, and by tube sheet and case weld；Finally will be with circle
The end socket of cylindrical partition is installed at housing two ends, and is connected fixing with shell flange.
During heat exchanger work, shell-side fluid flows into from inlet tube 13, axially washes away straight tube tube bank and serpentine pipe in housing
Tube bank, and carry out heat convection with straight tube and serpentine pipe, flow out from outlet 5.Corresponding with serpentine pipe tube side two kinds of straight tube tube side
Various heat exchange medium, separately flows into straight tube 10,11 and from straight tube tube side fluid inlet tube 8 and serpentine pipe tube side fluid inlet tubes 9
Serpentine pipe 12, and with shell-side fluid heat-shift, finally from straight tube tube side fluid outlet 15 and serpentine pipe tube side fluid issuing
Pipe 14 flows out.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Within the spirit of utility model and principle, any modification, equivalent substitution and improvement etc. made, should be included in this utility model
Protection domain within.
