Description

The high-efficiency bellows condenser
Technical field
The utility model relates to a kind of employed solution-air of chemical industry, oil, metallurgy and Thermal Power Engineering or liquid-liquid cold condenser of being used for.
Background technology
Existing solution-air or liquid-liquid cold condenser are made of housing and two ends end socket thereof and the heat exchanger tube that is arranged on enclosure interior, because its heat exchanger tube is a light pipe, then heat exchange efficiency is low, and fluid resistance is big, influence the heat exchange effect, and resistance to corrosion is poor.
Summary of the invention
The purpose of this utility model is exactly in order to address the above problem, the high-efficiency bellows condenser that provide a kind of heat transfer efficiency height, heat exchange area is big, fluid resistance is little, anti-dielectric corrosion ability is strong.
Technical solution of the present utility model:
A kind of high-efficiency bellows condenser, it includes the capping at housing and two ends thereof, be provided with heat exchanger tube by tube sheet in the housing, in capping, be provided with medium import and media outlet, on housing, be provided with material inlet and material outlet, wherein, heat exchanger tube or many straight tubes that are arranged side by side, or the many U type pipes that are arranged side by side, the tube wall that it is characterized in that each heat exchanger tube is a ripple struction, and the inner surface of each heat exchanger tube tube wall is provided with porous metallic layers.
The utility model changes the structural pipe wall of heat exchanger tube into ripple struction, and its inner surface scribbles porous metal material, housing employing rod baffle support tube bank.So corrugated tube of the present utility model compares with traditional heat exchanger tube, characteristics such as have the heat transfer coefficient height, flow resistance is low, and anti-dielectric corrosion ability is strong.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of high-efficiency bellows of the present utility model.
The specific embodiment
As Fig. 1,2, high-efficiency bellows condenser of the present utility model, it includes the capping 2 at housing 1 and two ends thereof, be provided with heat exchanger tube 4 by tube sheet 3 in the housing 1, in capping 2, be provided with medium import 5 and media outlet 6, on housing 1, be provided with material inlet 7 and material outlet 8, wherein, heat exchanger tube 4 can be many straight tubes that are arranged side by side, also many U type pipes that are arranged side by side, characteristics of the present utility model are that the tube wall of each heat exchanger tube 4 is a ripple struction, and the inner surface of each heat exchanger tube 4 tube wall is provided with porous metallic layers 9.
In the utility model, the ripple struction of the tube wall of each heat exchanger tube 4 can be continuous, also is interrupted, and preferably the two ends tube wall of each heat exchanger tube 4 is the even surface structure, so that fixedly connected with the tube sheet 3 at two ends, other is ripple struction.In the ripple struction of the tube wall of each heat exchanger tube 4 of the utility model, the peak-to-peak value between its crest and the trough is 0.1-3mm, is preferably 0.5-1.5mm.Can come support fixation by the many rod baffle 10 that are welded on the baffling circle in the middle of each corrugated tube 4, rod baffle 10 is thin round bar, is weldingly fixed on the baffling circle of annular with level or vertical direction respectively to constitute fixed support.Because of each corrugated tube 4 adopts the rod baffle supporting construction, then housing 1 fluid flow resistance can reduce to consistent with light pipe.
Porous metallic layers 9 of the present utility model can adopt 60-120 purpose aluminium powder, iron powder or nickel powder sintering or be painted on the inner surface of tube wall of corrugated tube 4 in vacuum high temperature furnace, form rough a large amount of aperture, can quicken vaporizing liquid greatly and generate bubble.The thickness of this porous metallic layers 9 is 0.1-0.6mm, best 0.2-0.3mm.
Efficient corrugated tube of the present utility model is with special equipment plain tube to be processed into the inside and outside continuous wave pattern shape curve shape that is, and according to dielectric property at bellows inside surface pyrolytic coating metal material, as Al, Fe or Ni etc.Because of this machining deformation is not to rely on the attenuate of thickness of pipe wall to form, but utilize the plasticity and the toughness of material, allow metal flow form, so at crest, trough place wall thickness attenuate not, machining stress is little, and stress distribution is even, do not have stress concentration point, can bear the big temperature difference and big pressure reduction.The corrugated tube inner surface has porous coating, increase by 10 times of surperficial products, improved the turbulence intensity of fluid greatly, constantly change flow rate of fluid and flow direction, destroyed laminar sublayer, changed the flow regime of medium side interlayer, destroyed or the elimination of thermograde between from the tube wall surface to the main flow, improve the inside and outside heat transfer coefficient of pipe greatly, and under low flow velocity, can reach turbulent condition.Because of tube wall surface has porous metal coating, make that thermograde is very little in the tube wall, thermal resistance is little, overall heat-transfer coefficient improves 2-5 doubly than common tube.And because the heat exchanger tube inner surface forms uneven and a large amount of apertures, the medium that is cooled is in heat exchanger tube surface heat release.Medium can reach turbulent flow, particularly medium disturbance in pipe in advance under lower flow velocity, play the effect of washing away automatically, and is less scaling, increased heat transfer efficiency and heat exchange area, also has saving manufacturing expense, characteristics such as simple in structure simultaneously.Can be widely used in oil, petrochemical industry, thermal power engineering field.
