With reference to the accompanying drawings and examples, specific embodiments of the present invention will be described in further detail.Following instance
For illustrating the present invention, but it is not intended to limit the scope of the invention.
In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " installation ", " phase
Even ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or be integrally connected；It can
To be mechanical connection, it is also possible to be electrically connected；It can be directly connected, can also can be indirectly connected through an intermediary
Connection inside two elements.For the ordinary skill in the art, above-mentioned term can be understood at this with concrete condition
Concrete meaning in invention.
In addition, in the description of the present invention, unless otherwise indicated, " multiple ", " more ", " multiple groups " be meant that two or
It is more than two.
As shown in Figures 1 to 3, the scale-proof heat exchanger of the present embodiment, including：The end socket 3 of tube sheet 2, two of shell 1, two and more
A heat exchanger tube 4, the both ends of shell 1 have opening, and the side wall of shell 1 is equipped with shell side liquid mouth 11, as shown in Figure 1, shell side liquid mouth
11 be two, is respectively arranged on the end positions of shell 1.Two tube sheets 2 are respectively arranged on the opening at the both ends of shell 1.Each end socket 3
It is connected to form end socket chamber 30 with a tube sheet 2 respectively, and each end socket 3 is equipped with tube side liquid mouth 31.Multiple heat exchanger tubes 4 are arranged in
Between two tube sheets 2 and it is connected to two end socket chambers 30；Retainer 5 is removably equipped in each heat exchanger tube 4, retainer 5 will manage
The lumen of body 4 is limited to multiple antiscale sections 40, is filled with an antiscaling block 6 in each antiscale section 40.
Retainer 5 is set in heat exchanger tube 4, heat exchanger tube 4 is limited to multiple antiscale sections 40, when in use, Tube Sheet of Heat Exchanger
When a certain range fluctuates, antiscaling block 6 floats the fluid flow of journey in antiscale section 40, with 4 inner wall collision friction of heat exchanger tube, subtracts
Few 4 encrustation of heat exchanger tube, extends the scavenging period of heat exchanger.While keeping the cleaning of 4 inner wall of heat exchanger tube, antiscaling block 6 is logical
Itself continuous rotation is crossed, fluid is disturbed, radial heat transfer temperature difference is reduced, achievees the purpose that augmentation of heat transfer.Work as use
After a period of time, antiscaling block 6 is worn, and needs replacing antiscaling block 6, at this point, retainer 5 is removed heat exchanger tube 4, is taken out and is worn
Antiscaling block 6；When mobile retainer 5 enters heat exchanger tube 4, it is sequentially placed into new antiscaling block 6, can be weighed after assembling end socket 3
Newly come into operation.
Retainer 5 is there are many fixed forms in heat exchanger tube 4, such as uses fixing clamp fixed retainer 5.In order to preferable
Ground fixed retainer 5, and it is convenient to replacement antiscaling block 6, in the present embodiment, the both ends of heat exchanger tube 4 are equipped with internal screw thread, each interior
Screw thread is all connected with a cored screw 7, and cored screw 7 is used for fixed retainer, i.e., as shown, two cored screws 7 clamp
Retainer.User can replace antiscaling block 6 by dismantling the cored screw 7 of any one end.
Preferably, heat exchanger tube 4 is uniformly arranged on tube sheet 2, and heat exchange is made uniformly to improve heat transfer effect.
Further, for convenience in turning cored screw 7, cored screw 7 is connected with fixed end 8, and fixed end 8 is set
There is liquid through-hole 81.Fixed end is set, can not need to use spanner work when installation or during replacement antiscaling block 6
Tool.
Further, antiscaling block 6 is made of metal or plastics.Preferably, antiscaling block 6 can be with engraved structure, can also be with
Solid construction, shape can be sphere, polyhedron or bouquet body.In the present embodiment, antiscaling block 6 be made hollow out polyhedron or
Hollow out sphere.Using engraved structure, the mobile performance of fluid is preferable, reduces the inner tube of heat exchanger journey liquid due to caused by antiscaling block
Pressure drop.For antiscaling block 6 made of metal, it is preferred to use the lesser metal of the hardness such as aluminium is made, and avoids heat exchanger tube by antiscale
Block abrasion；For antiscaling block made of plastics, it is preferred to use silicone plasties are made.
Further, retainer 5 includes frame body 51 and multiple fixed knots 52 on frame body 51.Frame body 51 has a variety of
Way of realization, for example, by using a bar.In the present embodiment, as shown in Figures 2 and 3, frame body 51 of the invention includes multiple stocks 511
With multiple reinforcing annulus 512, multiple stocks 511 are circular layout, and multiple reinforcing annulus are connected on stock 511.With multiple
Every the reinforcing annulus 512 of arrangement, when extracting retainer 5 out, the inner wall that can exchange heat pipe 4 plays the role of sweeping, and removing is changed
The fouling of heat pipe inner wall.
The calculating formula of antiscaling block power suffered in heat exchanger tube is in the present invention：
V×ρq× g=V × ρf×g+△P×A
Wherein, V is antiscaling block volume, ρqFor the density of antiscale block of material, ρfFor fluid density in heat exchanger tube, △ P is antiscale
Block is along the front and back pressure difference in tube fluid direction, and A is the maximum secting area of antiscale filler, and g refers to gravity constant.
In the present invention, the antiscaling block in each heat exchanger tube can it is identical with structure, volume is identical and material is identical, can also be with
It is not exactly the same.Such as：
According to above-mentioned calculating formula, the volume of multiple antiscaling blocks in same heat exchanger tube is not exactly the same, multiple antiscaling blocks
Material is identical.In certain fluid flow and pressure limit, antiscaling block will be in position different in heat exchanger tube, and with stream
Amount or the fluctuation of pressure move up and down in a certain range, and with heat transfer tube wall collision friction, remove dirt, keep heat exchanger tube
The cleaning of inner wall.
It, can also be using antiscaling block made of different densities material, specifically by tube side fluid according to above-mentioned calculating formula
Flow and property determine.
It should be noted that setting not exactly the same for the antiscaling block in each heat exchanger tube, such as the incomplete phase of material
Together, volume is not exactly the same or shape is not exactly the same, or even is different from.
It should be noted that as shown in figure 4, Fig. 4 shows the heat exchanger tube cross-sectional view of another embodiment.The present embodiment
In, cored screw 8 only is set in one end of heat exchanger tube 4, other end setting stop collar 41 is limited.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
