Using the technical scheme of the present embodiment, when heat exchanger in use, fluid enters heat exchanger from the first end of heat exchanger,
By fluid to clean spiral active force, drive cleaning spiral 6 move and/or vibrate, by clean spiral 6 motion and/
Or vibration is clean by the Fouling Cleaning inside the heat exchanger tube of heat exchanger.Said structure realizes heat exchanger and need not be stopped i.e.
Dirt that can be in automated cleaning heat exchanger tube.Technical scheme efficiently solves asking for the on-line cleaning of heat exchanger
Topic.
In the technical scheme of the present embodiment, the first housing is lower tube box, and the second receiving space forms boiling-house, lower perforated plate
It is arranged on the first end of heat exchanger main body and heating tube 7 is formed and fixes.
As shown in figure 1, in the technical scheme of the present embodiment, cleaning part is the cleaning spiral 6 with helical structure, cleaning
Spiral 6 telescopically moves in heating tube 7.Fouling Cleaning in heating tube 7 is clean, and the fouling in heating tube 7 is not also
When very firm, cleaning spiral 6 is under the active force of fluid, by the motion of itself by the dirt removal in heating tube 7.Above-mentioned knot
It is easy that structure is set, compact-sized.Specifically, clean spiral 6 steel wire diameter in 1mm between 3mm.Clean the pitch of spiral 6
For 0.8 to 1.5 times of the internal diameter of heating tube 7.Clean spiral 6 external diameter and heating tube 7 internal diameter between gap in 3mm extremely
Between 10mm.Cleaning spiral 6 is made up of elastic yarn.
As shown in figure 1, in the technical scheme of the present embodiment, heat exchanger also includes guide frame, position limiting structure and reinforcing
Cap 5, guide frame are fixed on the second fixed structure, and position limiting structure is arranged on guide frame, are strengthened cap 5 and are movably arranged
Limited on guide frame and by position limiting structure, the second end of cleaning part, which is fixed on, strengthens on cap 5.The setting for strengthening cap 5 increases
The active force of fluid and cleaning part is added, has so been advantageous to remove the dirt in heating tube.Specifically, strengthen in the present embodiment
Cap 5 is umbrella-shaped structure (as shown in Figure 2).Certainly, the form of reinforcing cap 5 has a variety of, and reinforcing cap 5 is bowl structure 18 (such as Fig. 3 institutes
Show) or chondritic (as shown in Figure 4) it is also possible.
As shown in figure 1, in the technical scheme of the present embodiment, guide frame is guide rod 2, and the first end of guide rod 2 is consolidated
It is scheduled on the second fixed structure, the second end of guide rod 2 extends for free end and to the direction of heating tube 7, guide rod 2 and heating
Pipe 7 is coaxially disposed.On the one hand said structure has guiding function, another aspect guide rod 2 and heating to the direction for cleaning spiral 6
Pipe 7 is coaxially disposed the drag losses for reducing fluid matasomatism on cleaning spiral 6.
As depicted in figs. 1 and 2, in the technical scheme of the present embodiment, strengthening cap 5 has mounting hole, and guide rod 2 is arranged on
In mounting hole, the diameter of mounting hole is more than the diameter of guide rod 2 and moved so as to strengthen cap 5 along guide rod 2.Said structure easily adds
Work, convenient installation.
As shown in figure 1, in the technical scheme of the present embodiment, position limiting structure includes gag lever post 4, and gag lever post 4 includes first
Gag lever post and the second gag lever post, the first gag lever post and the second gag lever post are arranged on guide rod 2, the first gag lever post and the second limit
Spacing between the bar of position is more than the length for strengthening cap 5.In the certain limit that said structure limits cleaning spiral 6, so clean
Spiral will not be wound mutually.
As shown in figure 1, in the technical scheme of the present embodiment, heating tube 7, guide rod 2 and position limiting structure be it is multiple,
Guide rod 2 is set correspondingly with heating tube 7, and position limiting structure is set correspondingly with guide rod 2.Multiple position limiting structure institutes
Plane it is at least partly different.Said structure can increase the external diameter setting for strengthening cap 5.
As shown in figure 1, in the technical scheme of the present embodiment, heat exchanger also includes coupling spring 11, coupling spring 11
First end is fixed on first fixed structure and in the first accommodating chamber, the second end of coupling spring 11 and the first of cleaning part
End is connected.On the one hand the setting of coupling spring 11 is advantageous to cleaning part vibration damping.On the other hand, spiral 6 and coupling spring are cleaned
11 have different coefficient of elasticity, and specifically, the coefficient of elasticity of coupling spring 11 is less than cleaning spiral 6, in the active force of fluid
