The elementary cell of open-frame type gasifier is heat exchanger tube, is made up of finned tube, inner tube and three part of plug-in part, functionally
Gasification section and bringing-up section can be divided into.As heat exchanger tube is used as the critical elements of high efficient heat exchanging, therefore inner tube dimensional requirement is smart
Degree is high.Do not require nothing more than inner tube accurately to assemble with finned tube and pipe inner rib plate, and require in use, internally on spiral
The position for rising the lower inner tube of LNG and NG effects can not change, and will otherwise directly affect the stability of equipment operation.At present,
On market, open-frame type gasifier heat exchanger tube used, due to all setting pipe inner rib plate inside gasification section and bringing-up section, increases
The manufacture difficulty of equipment, and increased the cost of equipment.Therefore, design a kind of open-shelf for simplifying easy to install and good effect of heat exchange
Formula gasifier is extremely urgent with heat exchanger tube.
The content of the invention
For the problems referred to above, the purpose of this utility model is to provide and a kind of simplifies the open-shelf of easy to install and good effect of heat exchange
Gasifier heat exchanger tube.
For achieving the above object, this utility model takes technical scheme below：A kind of open-frame type gasifier heat exchanger tube, its
It is characterised by：It includes the outer tube that exchanges heat, and the heat exchange outer tube includes gasification section and is fastenedly connected the bringing-up section of the gasification section；
The inner tight of the gasification section is provided with heat exchange inner tube, and female thread or ripple are provided with the inwall of the heat exchange inner tube,
Interpolation fin is installed in the inner tight of the bringing-up section, the end of the heat exchange inner tube is connect with the top of the interpolation fin
Touch.
The interpolation fin is spiral M shape interpolation fin of the cross section in M shape.
When arranging female thread on the inwall of the heat exchange inner tube, the height of the female thread is more than or equal to the heat exchange inner tube
The 1/5 of internal diameter.
When arranging female thread on the inwall of the heat exchange inner tube, the female thread is horizontal stricture of vagina or twill.
When arranging ripple on the inwall of the heat exchange inner tube, using double-deck ripple, the height of every layer of ripple is big for the ripple
In 1/4 equal to the heat exchange inner tube internal diameter.
Due to taking above technical scheme, which has advantages below to this utility model：1st, this utility model is provided with heat exchange
Inner tube, is provided with female thread or ripple in heat exchange inner tube, by increasing capacitance it is possible to increase the heating surface (area) (HS of fluid in heat exchange inner tube, while strengthening
The flow disturbance of fluid, good effect of heat exchange.2nd, this utility model is provided with interpolation fin, inwall of the interpolation fin along heat exchange outer tube
Arrange in the shape of a spiral, the cross section of interpolation fin is in M shape, the flowing that can further increase heat exchange outer tube fluid is disturbed
It is dynamic, improve heat transfer effect.3rd, this utility model is provided with heat exchange outer tube, heat exchange outer tube inside be provided with heat exchange inner tube and
Interpolation fin, this utility model pressure drop are reduced, simple structure, are easily installed.

Specific embodiment
With reference to the accompanying drawings and examples this utility model is described in detail.
Embodiment one
Shown in Fig. 1～3, the utility model proposes open-frame type gasifier heat exchanger tube, it include exchange heat outer tube 1, heat exchange
Outer tube 1 includes the bringing-up section 12 of gasification section 11 and connection gasification section 11.It is provided with the inner tight of heat exchange 1 gasification section 11 of outer tube
Heat exchange inner tube 2, is provided with female thread 21 (as shown in Figure 4, Figure 5), by increasing capacitance it is possible to increase heat exchange inner tube 2 on the inwall of heat exchange inner tube 2
The heating surface (area) (HS of interior fluid, while strengthening the flow disturbance of fluid.In the inner tight of heat exchange 1 bringing-up section 12 of outer tube is provided with
