Description
Technical field
The utility model relates to condenser, especially relates to a kind of high-efficiency vertical condenser.
Background technology
Condenser has the heat exchanger of phase transformation as side, mainly carries out condensation heat transfer process, is widely used in the industries such as chemical industry, petrochemical industry, refrigeration.For the heat transfer process having phase transformation, feature is that the fluid temperature (F.T.) undergone phase transition remains unchanged substantially, under the relatively little temperature difference, carry out heat exchange; Heat exchange amount is mainly latent heat r, and r is generally comparatively large, and therefore required heat transfer coefficient is higher; Affect the physical property of phase-change heat-exchange except the influence factor of monophasic fluid, also have latent heat, surface tension and buoyancy lift etc.; Because phase transformation produces condensate liquid, condensate liquid is that heat transmits further and adds thermal resistance.The thermal resistance that condensate liquid liquid film brings and flow condition thereof make flow morphology become complicated, add difficulty for controlling whole heat transfer process preferably.
Condensation heat transfer is mainly divided into film condensation and dropwise condensation.Film condensation is that condensate liquid forms thin film along whole wall, and flows under gravity, and the latent heat of vaporization that condensation is released must pass through liquid film, and therefore, thickness of liquid film directly affects heat transmission; When coagulating liq well can not infiltrate wall, then on wall, form many little liquid pearls, now the part surface of wall directly contacts with steam, and therefore, heat exchange rate is much larger than film condensation (may greatly several times, an even order of magnitude).Condensation process is strictly upper to be said, is first to be transitioned into membranaceous by pearl, condenses to a certain degree at pearl, and condensate liquid increases and just can be formed membranaceous, and therefore desirable state namely completes heat exchange in pearl condensation process; Reach this ideal state to be difficult to, these needs coordinate structural design flexibly under higher heat exchange efficiency.
The principle of Augmentation of condensation heat transfer is the thickness of the liquid film of thinning viscous on heat exchange surface as far as possible, and it is thin that schedule of reinforcement can make the liquid film of condensation thereon draw with some special surfaces, or the liquid condensed is drained from heat exchange surface as early as possible.In order to strengthen flow disturbance, promote heat convection, condenser thermal transfer element by new and effective coil pipes such as initial light pipe elliptical tube finally, bellows, different drop shaped tube and alternating curved bellowss, then is become heat transfer element board-like finally from tubular type.In these methods, although can enhanced heat exchange largely, to a certain degree change coagulation forms, these special designs all result in fluid-pressure drop and greatly raise, and the flexibility of these device structures is lower, can not adjust according to the change of operating mode; Meanwhile, the gasket seal corrosion-vulnerable in conventional plate type heat exchanger is also a weak link.
In addition, gravity acceleration g has a significant impact heat transfer free convection.Nusselt number Nu is the accurate number characterizing heat convection intensity, and Nu larger expression heat convection is stronger, and its expression formula is as follows:
Nu＝f(Gr，Pr)
Wherein,
so Nu is directly proportional to gravity acceleration g.
Therefore,
heat exchange is strengthened.For heat exchanger form, conventional shell and tube is horizontal, and this just reduces heat exchange efficiency in form.

One, change the coagulated state of condensate liquid, reduce thermal resistance;
Contact and rough surface are that condensation of gas provides liquefaction core.For shell side condensation heat gas, due to the existence of contact between plate, contact part does not have cold-side fluid to pass through, therefore shell side gas by have contact local time, heat exchange degree is weak relative to there be not the place of contact, has therefore upset the formation homogeneity of condensate liquid, has made condensation process close to dropwise condensation, reduce thickness of liquid film, reduce thermal resistance.
Two, sheet structure parameter can flexible modulation;
According to different working condition requirements, can flexible modulation distance between plates, plate to spacing and contact density, reach heat transfer effect in various degree.Because there are these architectural characteristics flexibly, condensation process can be controlled and mainly carry out under pearl condensing state.
Three, heat exchange efficiency is high, saves occupation area of equipment;
Owing to having contact between plate, the disturbance of energy larger fluid, makes the liquid form of liquid be turbulence state, greatly enhances heat transfer.Simultaneously for the fluid having gaseous state, the uneven cavity between plate pair can strengthen the disturbance of gas, increases gassiness side heat exchange (gas heat-transfer efficiency is general lower) largely.Higher heat exchange efficiency, means that the heat exchange area needed for heat transfer effect reaching same is less, not only reduces the floor space of equipment like this, decrease the difficulty of the installation of equipment, maintenance clean etc. equally.
