Embodiment
The utility model is further explained with reference to embodiment and accompanying drawing.Following embodiments do not limit in any form
The utility model processed.All technical schemes obtained by the way of equivalent substitution or equivalent transformation, are in the utility model
Protection domain among.
Fig. 1 is a kind of schematic diagram of heat exchanger with flight according to the utility model embodiment.The heat exchanger includes
Heat exchanger body 1 and multiple flights.2 be left-turn spiral piece, and 3 be right hand helix piece.Wherein, the arbitrary cross section of flight
Width is identical, and the end face width of adjacent two flight is also identical, and adjacent two flight is using the central point of its contact face as weldering
Contact, 90 ° of interaction link together.Flight is cut entirely with heat exchanger body 1 on whole hand of helix with heat exchanger inwall
Face uses welding structure, to ensure intensity requirement.Wherein, flight uses mold cold-press moulding, and production efficiency is high, and quality is steady
Fixed, presentation quality is good.Flight needs welded and installed in heat exchanger body after machining, therefore helical pitch of its mold used etc.
In flight helical pitch plus the helical pitch springback capacity after blank cold pressing.Process the flight such as 3 of different ratio of height to diameters：1、2：1、1.8：1、
1.5：1、1.2：When 1, it is also necessary to be tested to determine the helical pitch of blank to the blank of flight.
Fig. 2 is welding flight heat exchanger top view.Adjacent flight is divided into left-turn spiral piece and right hand helix piece, left
Right hand helix piece intermeshes vertical 90 ° and linked together using the central point of connecting end surface as pad.Built-in flight end face
Width be less than the diameter of heat exchanger inwall, a small gap be present in built-in flight and heat exchanger inwall.Material is from top
To flowing down, left-turn spiral piece is flowed through, then right hand helix piece is flowed through again, passes through left-turn spiral piece, the flow direction of material is not
It is disconnected to change, with the increase of flow velocity, the vortex of fierceness is produced on mobile section, becomes the stratosphere liquid film of heat exchanger inner surface
It is thin, improve mass transfer area, increase Surface Renewal, strengthen mass transfer and heat transfer efficiency, it is ensured that without static region, prevent overheat with
Material aging, the newest oldest material of material substitution of heat exchanger body will be entered, be the renewal of peak efficiency.
Fig. 3 is flight fluting dimensional drawing.The thickness of flight is 1.5-3mm, and the centre of its at least side is provided with recessed
Groove, the groove extend along side.The groove is used to deposit solder and Welding of Heat-exchanger, ensures weld strength, prevents high viscous
The material of degree extrudes flight, comes off, and triggers accident.
Fig. 4 is flight end-beveling figure, and chamfering is in 30 ° -120 °.Material flows down from above, continuous in flow direction
While change, material is chamfered continuous shearing, breaks stream.The smaller shearing for being more beneficial to material of angle of chamfering, material become
It is more tiny, mix evenly, so as to which mass-transfer efficiency is higher.Meanwhile end-beveling is smaller, resistance is smaller, and pressure drop is also smaller, so as to
Energy consumption is saved, reduces running cost.
Using the heat exchanger of the present utility model with flight, material, to flowing down, flows through left-turn spiral above heat exchanger

Different ratio of height to diameters, ratio of height to diameter is smaller, and such as 3：1、2：1、1.8：1、1.5：1、1.2：1, then material is caused by mobile section
Vortex is fiercer, and liquid film is thinner, and Surface Renewal is faster, while mixes also evenly, so as to which mass transfer, heat transfer efficiency are higher.
Using the heat exchanger of the present utility model with flight, material, to flowing down, flows through left-turn spiral above heat exchanger
Piece, right hand helix piece then is flowed through again, passes through left-turn spiral piece, the flow direction of material constantly changes, and is chamfered and constantly cuts
Cut, with the increase of flow velocity, material produces the vortex and shearing force of fierceness on mobile section, makes thinning of liquid film, broken stream, material
Become more tiny, significantly improve mass transfer area, accelerate Surface Renewal, mixing is evenly.In the reinforcing mass transfer and the process of heat transfer
In, flight uses glossing with material contact side, reducing friction resistance, shortens residence time of material, it is ensured that not static
Region, prevent material overheat and aging, so as to effectively prevent pollute final products, improve product quality.In addition, flight side
Face is slotted for depositing solder, and contacting surface with heat exchanger body on whole hand of helix all welds, it is ensured that welding is strong
Degree, effectively prevents from extruding flight during highly viscous material-heat-exchanging, departs from, and triggers accident.
Therefore, a kind of heat exchanger with flight provided by the utility model, help to realize that good material is radially mixed
Conjunction and dispersion effect, alternate contact and the renewal at interface are effectively improved, strengthens mass transfer and heat transfer, improve reaction rate, saving energy
Consumption.Be applicable not only to the low usual heat exchanger of material viscosity, improve heat exchange efficiency, be more suitable for oil, chemical industry, fine chemistry industry,
High viscosity fluid or liquid in the industries such as plastic extrusion, environmental protection, mining and metallurgy are mixed, reacted, extracting, absorbing admittedly, plastic match colors, squeeze
Go out, conduct heat and the process such as polymer devolatilization.The devolatilization equipment of especially suitable Surface Renewal type, can be effectively by the newest thing of body
Material substitutes oldest material, realizes efficient renewal process.
It should be noted that embodiment of the present utility model has preferable implementation, and not the utility model is appointed
The limitation of what form, any one skilled in the art change or are modified to possibly also with the technology contents of the disclosure above
Same effective embodiment, as long as without departing from the content of technical solutions of the utility model, according to the technical essence of the utility model pair
