Description
Technical field
This utility model relates to a kind of heat-exchange device, and specifically, this utility model relates to a kind of double-tube heat exchanger, special
It it not the double-tube heat exchanger of a kind of disassembling cleaning.
Background technology
Double-tube heat exchanger is the dress that a kind of inner and outer pipes utilizing phase fit each transmits different temperatures media implementation heat exchange
Putting, this traditional heat-exchange device structure is very simple, it is easy, easy to use to make, therefore still occupies in existing market
The biggest share.But, prior art, in order to prevent double-tube heat exchanger from leaking, generally uses overall heat exchange structure., overall
The heat exchanger of structure use during the encrustation of once inner and outer pipes, heat exchanger effectiveness reduces accordingly.After this type of situation occurs
Because user cannot realize Physical snaking operation, heat exchanger integral replacing can only be made and process, although this simple replacement can
Solving the realistic problem in producing, its side effect is the increase in user's application cost.
Utility model content
After this utility model is mainly for prior art products once fouling, user cannot implement what Physical snaking processed
Problem, proposes a kind of dismountable double-tube heat exchanger.This kind dismountable heat exchanger structure is simple, connection is reliable, dismounting is easy,
It is important that the exposed windows that partial disassembly is formed, user may utilize window and implements Physical snaking operation.Sleeve pipe change
After hot device obtains the process of efficient snaking in time, easily return to original specified heat exchange efficiency.
This utility model is achieved through the following technical solutions technical goal.
Dismountable double-tube heat exchanger, it includes inner tube, outer tube, joint, oblique bend pipe, flat bend pipe and adapter.Said inner tube with
Outer coaxial tube fit, adjacent outer tube one end is connect by radially connected adapter series winding, and the inner tube of front and rear row is curved by joint peace
Pipe realizes the series winding that turns round and connects, and the inner tube of up-downgoing realizes the other end series winding that turns round by joint and oblique bend pipe and connects.Its improvements
It is: described joint is one group of dismountable flange joint, and wherein the outer shoulder of large aperture flange docks with outer tube end, opposite side
The outer shoulder of small-bore flange connects flat bend pipe or oblique bend pipe, and large aperture flange and small-bore flange opposing end surface respectively set a phase
With the interior shoulder of size, interior shoulder configures the pressure ring matched, and between interior shoulder and outer wall of inner tube, plug dress gasket seal, is positioned at
Pressure ring therein is compacted gasket seal along with the bolt regulation of flange joint configuration, directly constitutes dismountable end sealing knot
Structure.
In said structure, described gasket seal is graphite product, and gasket seal bundle is on inner tube pipe end outer wall.
In said structure, the external diameter of described pressure ring is equal to the interior shoulder aperture of large aperture flange or small-bore flange, and two
Person's matched in clearance.
This utility model compared with prior art, has the positive effect that:
1, the string that turns round between inner tube or between outer tube is connected by dismountable end sealing structure, this simple in construction, connects
Connecing easily, it is convenient to dismantle；
2, i.e. form, after dismantling flat bend pipe or oblique bend pipe, window of removing contamination, it is simple to implement physical method and remove in inner and outer tubes
The dirt of wall；
3, owing to taking out stains in time, can avoid double-tube heat exchanger used too fast fall effect or lose efficacy, therefore user is not
Needing frequent integral replacing, its result is to greatly reduce use cost.

Detailed description of the invention
Below according to accompanying drawing and in conjunction with the embodiments, the utility model is described in further detail.
Dismountable double-tube heat exchanger shown in the drawings, it includes inner tube 1, outer tube 2, joint 3, oblique bend pipe 4, flat bend pipe 5 and
Adapter 6.Said inner tube 1 fit coaxial with outer tube 2, adjacent outer tube 2 one end is connect by radially connected adapter 6 series winding, front and rear row
Inner tube 1 realize, by joint 3 peace bend pipe 5, the series winding that turns round and connect, the inner tube 1 of up-downgoing realizes separately by joint 3 and oblique bend pipe 4
One end series winding that turns round connects.Joint 3 in this utility model is one group of dismountable flange joint, wherein macropore diameter flange 3.1
Outer shoulder docks with outer tube 2 end, and the outer shoulder of other end small-bore flange 3.4 connects flat bend pipe 5 or oblique bend pipe 4, large aperture
Flange 3.1 and small-bore flange 3.4 opposing end surface respectively set the interior shoulder of a same size, and the pressure ring 3.3 of interior shoulder configuration is adopted
By matched in clearance, plug dress gasket seal 3.2 between interior shoulder and inner tube 1 outer wall, the gasket seal 3.2 in the present embodiment is stone
Ink goods, gasket seal 3.2 is directly restrainted on inner tube 1 pipe end outer wall.The pressure ring 3.3 disposed between two flanges, along with method
The bolt of Lan Jie configuration regulates and is compacted gasket seal 3.2, directly constitutes dismountable end sealing structure.
By after dismountable double-tube heat exchanger actually used a period of time that this utility model is made, compared with technical products one
Sample, inside pipe wall certainty residual soil, thereby result in heat exchanger effectiveness and decline problem, user can according to practical situation at the appropriate time
Shut down and make internal snaking process.First, unscrewing joint 3 respectively, dismantle flat bend pipe 5 and oblique bend pipe 4 the most successively, these turnings are even
Fitting i.e. forms window after laying down, and this window leads directly to inner tube 1 and outer tube 2 inwall, is conducive to implementing physical method and removes inner tube 1 He
The dirt of outer tube 2 inwall residual.Owing to snaking can be implemented in time, double-tube heat exchanger used too fast fall effect can be avoided or lost efficacy,
Therefore user is not required to frequent integral replacing, and its result is to be substantially improved heat exchange efficiency, and reduces use cost.
