As shown in Figure 1, the utility model provides a kind of spiral turbolator, including the spiral helicine turbolator main body of cylindrical type
100, the turbolator main body 100 is equipped at intervals with several perforation 110, the top edge of each perforation 110 along its length
Place is equipped with flow-disturbing valve 120, and the flow-disturbing valve 120 is to the separate turbolator main body 100 and tilts down extension.It is spiral
200 high temperature flue gas of pipeline can be become spiral turbulence state from laminar condition by turbolator main body 100, increase air-flow in pipe
The distance flowed through.In order to further increase the heat exchange efficiency of high-temperature flue gas, interval opens up several perforation in turbolator main body 100
110, and the flow-disturbing valve 120 extended obliquely is arranged in 110 edges in each perforation, high-temperature flue gas is when flowing through turbolator, portion
Divide gas that can pass through from perforation 110, this portion gas is mutually impacted with the gas for not flowing through perforation 110, can aggravate high temperature
The turbulent operating condition of flue gas spreads the thermal energy of the high-temperature flue gas close to pipeline center part greatly to tube wall, but also
The time by turbolator of high-temperature flue gas is further increased, to improve the heat exchanger effectiveness of high-temperature flue gas.
Common twisted piece formula turbolator is typically all to be made of the thin steel distortion of a piece of strip, in order to reach certain torsion
Rate, it may be necessary to steel disc be reversed into biggish angle, if the ductility of steel disc material is poor, can be interrupted in twist process
It splits.As shown in Fig. 2, in order to reduce technology difficulty, even if can also produce torsion rate in the case of steel ductility is poor and meet
It is required that spiral turbolator, can be cross long bloom 300 with cross section be raw material, torsion production spiral turbolator.
Cross section approximation using the spiral turbolator of which production is in X-shaped.In addition, the spiral turbolator master produced using which
100 structure of body compare common twisted piece formula turbolator more consolidate it is durable.Cross long bloom 300 is it is considered that it has 4
The blade 310 being fixedly connected with each other, and the angle between adjacent blades 310 is 90 °.Similarly, if continuing growing the number of blade,
For example lobe numbers are 6, then the angle between adjacent blades becomes 60 °, carries out torsion life using the long bloom of 6 blades
Spiral turbolator is produced, then to reach identical torsion rate, the angle of torsion will be further decreased.
As shown in figure 3, setting spiral turbolator adjacent segments away from as L, the radius of exhaust gases passes is r, then spiral turbolator
Torsion rate Y are as follows:
In one embodiment of the utility model, the radius of exhaust gases passes is 120mm, the torsion rate of the turbolator main body

As shown in Figure 1, exacerbating the turbulent flow of high-temperature flue gas after adding perforation 110 in spiral turbolator main body 100, extend
Residence time of the flue gas in pipeline 200, still, high-temperature flue gas be not in pipeline 200 residence time it is more long more
It is good, if high-temperature flue gas prolonged stay in pipeline 200, it will affect whole heat exchange efficiency.If the perforation 110 and described
If the size and shape of flow-disturbing valve 120 are different, high-temperature flue gas may form more complicated turbulent operating condition in flue, from
And the timely discharge line 200 of flue gas after heat exchange is influenced, so, it, can be by the perforation in order to guarantee whole heat exchange efficiency
110 and the flow-disturbing valve 120 be set as identical size and shape, so that heat exchange and exhaust are balanced, so that overall heat exchange efficiency
Reach higher level.In addition, in order to further enhance the smoothness of high-temperature flue gas flowing, it can be by the flow-disturbing valve far from institute
One end edge for stating turbolator main body forms arc.
Flow direction of the high-temperature flue gas in pipeline 200 is from lower from upper, so the extending direction of the flow-disturbing valve 120
It is that obliquely, i.e., the angle formed between the described 120 place plane of flow-disturbing valve and the section of the perforation 110 is acute angle.This
Utility model does not do particular determination to the angle formed between the 120 place plane of flow-disturbing valve and the section of the perforation 110.
In some embodiments of the utility model, formed between the 120 place plane of flow-disturbing valve and the section of the perforation 110
When angle is 30 °~50 °, flow-disturbing and heat transfer effect are preferable.
As shown in figure 4, safeguarding or replacing spiral turbolator, in some embodiments of the utility model, institute for convenience

It extracts out or is inserted into road 200.
In one embodiment of the utility model, the pulling part 130 is closed hoop structure 131, the cyclic annular knot
Structure 131 can be circular annular form structure, rectangular ring structure or other regularly or irregularly cyclic structures.Operator
Finger can be protruded into ring, so that it may easily lift spiral turbolator.The material of the cyclic structure 131 can be and disturb
The identical metal of sub- 100 material of main body is flowed, is fixed in the top of the turbolator main body 100 by welding, connection is more
Add firm.
In another embodiment of the utility model, the pulling part 130 is plate structure 132, and shape can be square
Shape or other shapes.Operator lifts spiral turbolator by pinching plate structure 132 with hand.Similarly, plate structure
132 can be metal material identical with 100 material of turbolator main body, pass through welded connecting.
The pulling part 130 of spiral turbolator is if it is the preferable metal of thermal conductivity, then the pulling part 130
