The liquid of near-wall strengthen the design of flow-disturbing, the scale velocity for slowing down heat exchange tube wall is reached, while in the company of flexible shaft
Connect down, the spiral band in plug-in part also plays the role of to scrape scale removal to tube wall.
Combined type flow-disturbing antiscale plug-in part in a kind of heat exchanger tube of this secondary design, the invention is designed spiral band and support member
Combine, radius of its overall radius less than heat exchanger tube.It is built-in to be set to support member, support member by supporting plate, rotating end cap,
Hollow shaft three constitutes, and wherein together with a welding hollow shaft, this invention sets the supporting plate on support member in hollow shaft
Four supporting plates are put, in order that the plug-in part is rotated with liquid, one end of supporting plate is provided with rotating end cap.Exterior is set to
Spiral band, in connecting hole on the supporting plate by rotating the axle on tie, is connected to by way of hole axle gap coordinates
On the border of heat exchange tube wall.Under the working condition of heat exchanger tube, liquid starts support member by outside rotating end cap
Rotation, spiral band rotates also with the flowing of liquid around the hollow shaft of support member, meanwhile, spiral band is also in shaft hole matching
Under, itself starting to rotate, several spiral band combinations rotate the further flow-disturbing state for increasing inside pipe wall, while
The boundary layer dirt layer around tube wall is destroyed, the effect of antiscaling, descaling is reached.
Supporting plate on support member can be evenly distributed around hollow shaft in hollow shaft so that under flowfield impingement, around sky
Heart axle Rotating with Uniform, under given conditions, supporting plate can be around hollow shaft uneven distribution so that produce specific direction deflection,
While rotation, strengthen the friction to side tube wall, for four are evenly distributed on hollow shaft surrounding in 1- Fig. 5 in figure below
Supporting plate.
The radius of supporting plate is adjusted according to the radius of heat exchanger tube, less than heat exchange tube diameter 1mm~2mm, blade shape
It is arc-shaped.
Axle is provided with outside spiral band to be connected with the rotation hole in supporting plate in support member, supporting plate and hollow shaft
Connect through welding etc. mode.
Rotating end cap is connected in the hollow shaft of support member by welding manner.
The connected mode of plug-in part can be connected with iron wire iso-deflection axle.
The present invention has advantages below:
(1) rotating end cap set in this combined type flow-disturbing antiscale plug-in part makes the device that rotation is produced under the flowing of fluid
The moment of torsion for turning reaches the effect of plug-in part spin；
(2) support member set in this combined type flow-disturbing antiscale plug-in part increases heat exchange with the combining structure of spiral band
Flow-disturbing degree in pipe, while fluid scouring power is increased, shearing force of the increase fluid to dirt；
(3) when the spiral band set in this combined type flow-disturbing antiscale plug-in part is operationally contacted with heat exchange tube wall, meeting
The dirt on tube wall, and the rotation for passing through spiral band are scraped, the flow-disturbing degree around tube wall is further enhanced, antiscale is reached
The purpose of snaking.
(4) multiple spiral bands and the connection of support member are demountable structure, side in this combined type flow-disturbing antiscale plug-in part
Just clean, improve the service life of plug-in unit.
