The bellows tube of the utility model be it is a kind of cut by big small arc-shaped continuous phase, it is inside and outside shaped like undulatory thin-walled tube,
High official post fluid between its peaks and troughs receives strong disturbance, the three-dimensional motion of this disturbance outer fluid in pipe,
Therefore the degree of its disturbance is more strong and thorough, even if fluid flow rate is very low, can also become turbulence state, while tube wall
Thin temperature gradient is small, substantially reduces wall resistance, improves pipe internal-external heat exchanger coefficient, so that total heat transfer coefficient be made to improve.One
As for water-heat transfer water up to 1500-3500Kcal/ ㎡ .h. DEG C, vapour-water up to 2500-5000Kcal/ ㎡ .h. DEG C,
Its heat exchange efficiency is three times of general tubular heat exchanger.2. high temperature resistant can bear the larger temperature difference, pressure difference, though bellows tube wall is very thin
(0.5-0.8mm) mentions its bearing capacity significantly since it uses special free forming technique and unique circular arc shape
Height, laboratory measure bellows tube one-dimensional failure pressure and are generally 20Mpa or so, and pressure control is in 6.4Mpa or less in actual use
Still very safe.Waved tube heat exchanger adapts to reach as high as 450 DEG C compared with elevated operating temperature using stainless steel material simultaneously,
And bellows is a kind of flexible member, has certain thermal compensation ability, to larger operational difference operating condition, adaptability is good, equipment
Thermal stress is small, and more common tubulation has clear superiority.3. antiscale, descaling function are strong, fouling of heat exchangers, burn into blocking are always
A more scabrous problem, especially condition of water quality is poor, water treatment efficiency is bad, impure in steam medium or chemical reaction
In the case where foulant easily generated, this is particularly problematic.Less serious case's heat exchanger function reduction, degrading, resistance increase, energy
Consumption increases, and severe one heat exchanger, which blocks, to be unable to run, therefore heat exchanger maintenance, cleaning or the workload updated increase.Bellows tube changes
The stainless steel bellows tube of hot device, since using stainless steel quality material, itself is anticorrosive, and it is special that more important is bellows tubes
Inside and outside waveform, Turbulence Media constantly washes away the surfaces externally and internally of heat exchanger tube, and dirt is difficult to stockpile on surface, even if fouling, due to
Bellows tube is a kind of flexible member, during the work time by the effect of the temperature difference after, the curvature of bellows tube each section constantly becomes
Change, although the deformation of this Curvature varying bring is not very greatly that the linear expansion coefficient of dirt and metal bellows tube differs greatly,
Therefore a biggish pulling-out force will be generated between dirt and node pipe surface, it is sufficient to so that dirt is fallen off and realize automatic clear up, automatically
Scale removal, special this point are that tubulation and other heat exchangers can not be compared.4. stress distribution is uniform, anti-corrosion capability is strong, by
In bellows tube using unique forming technology, i.e. " free forming " or " soft forming ".The process characteristic is: in forming process, becoming
Shape is not due to what metal forced flow in a mold was formed, but a kind of process of free-flowing or is referred to as " soft forming "
Process, this forming process not will cause stress concentration, residual stress is small, stress distribution is uniform, does not have due to not having imposed deformation
There is intergranular shortcoming, therefore there is very strong anticorrosion stress-resistant ability.5. long service life, reasonable price, since bellows tube uses
Ultra-thin-wall stainless steel material, on the one hand improves the service life of product, while also greatly reducing the weight of product, saves
About material, due also to the reduction of operation and maintenance cost, the reduction of occupied area mention the ratio of performance to price of product significantly
Height, economic benefit are obvious.
The utility model has the advantages that the utility model has the following advantages that compared with traditional heat exchanger, first: heat transfer coefficient is high,
Heat exchange efficiency is three times of general tubular heat exchanger；Second: have the characteristics that high temperature resistant, the larger temperature difference, pressure difference can be born, the
Three: having the function of antiscale, scale removal；4th: stress distribution is uniform, anti-corrosion capability is strong；5th: there is impact resistance, use the longevity
The characteristics of life length, reasonable price；6th: there is processing technology simplicity, can be processed using tradition machinery.Install it is simple and direct, and pass
Tubular heat exchanger installation procedure of uniting is consistent；7th: the operation of heat exchanger, it is easy to use, it saves and produces and uses cost；8th: should
Heat exchanger stability is good, can long continuous operation, no replacement is required part is long using the longevity；9th: the heat exchanger shell pass steam point
Two-way flowing, reduces pressure drop.The utility model can be promoted and mutually be exchanged heat for vapour-liquid simultaneously, the Chemical Manufacture of liquid-liquid heat exchange or
Person's test, takes high-volume to produce by batch, to supply the needs of Chemical Manufacture, has apparent practical value and economic value.
