Detailed description of the invention
For the ease of the understanding of those skilled in the art, the present invention is made further with accompanying drawing below in conjunction with embodiment
Bright.
The operation principle of the present invention is: install this device in pipeline, when pipeline has current to run, it is not necessary to additional dynamic
Power, utilizes the flow velocity of current self to drive the rotary part of this device, and i.e. variable pitch type helical blade 4, does not stops for a long time in pipeline
Ground quickly rotates (300-1800r/min), and changing the laminar condition of water in managing is turbulent condition, destroys the formation mechenism of incrustation scale,
Design philosophy is broken away from traditional passive clearout scale removal concept, has become passive scale removal into actively antiscale, also can strengthen simultaneously and change
Heat, increases substantially the coefficient of heat transfer K value more than 20% of pipeline.
The superelevation high-intensity magnetic field that permanent magnet produces, under the conditions of not changing the original chemical analysis of water, makes water mineral
Physical arrangement change.The flow velocity of light water is 0.5-1.0 meter per second, and stator magnetic ring 2, the amount of magnetizing of rotor magnetic ring 3 are roots
According to water velocity, pipe diameter determines an exact value.
Magnetic field more than 3000GS, allows light water with certain flow rate, cuts along the direction vertical with the magnetic line of force, by necessarily
The magnetic field of intensity, light water will become magnetic water.The originally macromole of association chain, fragments into single little molecule, hydrone
Dipole moment deflects.In water, the negative ions (dirt molecule) of dissolved salts is surrounded by single hydrone, makes the calcium in water, magnesium etc.
The acicular crystal of foulant changes into granular crystal body, adheres to each other and builds up characteristic and receive destruction, thus at heating surface or
Not tying hard scale on management wall, granular crystal body is then discharged with mudhole, simultaneously because hydrone dipole moment increases so that it is with salt
Negative ions captivation increases, and on make to be heated furnace wall, tube wall, original old dirt is by wash rice cracking, loose, self falling.
Magnetic suspension tube cleaning arrangement as shown in Figure 1, including magnetic suspension bearing, is connected with the rotating shaft 1 of magnetic suspension bearing
And along its axially extended variable pitch type helical blade 4；Magnetic suspension bearing also includes rotor magnetic ring 3, stator magnetic ring 2, rotor magnetic ring 3
It is suspended in stator magnetic ring 2 internal.It is provided with reinforcement between magnetic suspension bearing and variable pitch type helical blade 4.
Rotor magnetic ring 3 and stator magnetic ring 2 are equipped with two pairs of permanent magnetism annulus on band inclined-plane, stator magnetic ring 2 medial surface shape with
Rotor magnetic ring 3 lateral surface matches.The permanent-magnetic clamp of stator ring and the permanent-magnetic clamp of rotor annular are coaxially in rotating shaft, rotor magnetic ring 3
Axial charging equal with stator magnetic ring 2, rotor magnetic ring 3 is contrary with the magnetizing direction of stator magnetic ring 2, and between permanent-magnetic clamp, inclined-plane is mutually arranged
Scolding, produce the repulsion being perpendicular to inclined-plane, its component axially and radially, between making rotor suspension in the stator, it is ensured that rotor magnetic ring 3
Stably balance can be reached at six-freedom degree when rotating speed is sufficiently large.
Rotor magnetic ring 3 profile can be V-type, U-shaped, W type, S type etc., and stator magnetic ring 2 is matched therewith, rotor magnetic ring 3
Can be freely rotatable in stator magnetic ring 2.The lateral surface of stator magnetic ring 2 is non-circular.
As in figure 2 it is shown, current are laminar in installing magnetic suspension tube cleaning arrangement preceding pipeline additional, install magnetic suspension pipeline additional clear
After cleaning device, utilize front and rear angles poor, form gaps between their growth rates and produce turbulent flow, as it is shown on figure 3, destroy Raynaud phenomenon, allow in pipeline
Wall can not form steady flow condition, and asymmetric flow process disturbance is taken away substantial amounts of precipitate, thus kept the cleaning of inner-walls of duct.
Pipeline water side deposition makes pipe heat-transfer coefficient decline to a great extent.Owing to the thermal conductivity of incrustation scale is the lowest, only the 1/ of steel
30 1/200, thus drastically reduced the heat transfer coefficient of pipeline heat exchanger tube.
Table 1 be fouling on the energy saving of the stainless steel heat exchange tube that Ф 20 × 1.0 material is 307 to affect data (standby
Note: U.S. refrigeration circle authority Scientific Organizations Philip Kotz):
Table 1
Even if scale forming only has a few tenths of a mm, exchange heat pipe heat transfer coefficient also to have significant impact.In engineering design clearly
Clean coefficient takes 0.85, is about as much as the incrustation scale that only considered 0.1 mm of thickness, in the middle of actual motion, even if pipeline is taked
After Chemical cleaning, if not adopting an effective measure, such cleanliness factor also can only maintain less than 25 days.
The magnetic suspension tube cleaning arrangement of the present invention can make the cleanliness factor of heat exchanger tube maintain the high level of more than 0.85,
This is highly beneficial to pipeline heat exchange efficiency.
Above embodiment is only the technological thought that the present invention is described, it is impossible to limit protection scope of the present invention with this, all
It is the technological thought proposed according to the present invention, any change done on the basis of technical scheme, each fall within the present invention and protect model
Within enclosing.The technology that the present invention is not directed to all can be realized by existing technology.
