Spiral-plate heat exchanger, it is that two spirality channels are made by two parallel metal plate coils, leads between cold fluid and hot fluid
Cross the heat exchanger that spiral wooden partition is exchanged heat.Spiral-plate heat exchanger is widely used, many application field heat exchanger spirals
Sheet heat exchanger substitutes tubular heat exchanger.Spiral-plate heat exchanger heat conductive efficiency is good, has a self-cleaning effect, non-disconnectable formula structure it is close
Sealing property is good, suitable for hypertoxic, inflammable, explosive or precious fluids heat exchange.But although it has self-cleaning effect, due to
Design or misoperation can also block, and at this moment also be difficult to mechanically clean using dismountable structure, because internal
Do not allow after the chaotic dismounting of structure easy to clean.The shortcomings that spiral-plate heat exchanger maximum is that maintenance is difficult, and inner ring spiral plate such as occurs
Rupture, will make whole equipment scrapping, when pipeline of the medium by heat exchanger, it is undesirable to be usually present heat transfer effect.
Utility model content
The purpose of this utility model is overcome the deficiencies in the prior art, avoid heat exchanger occur when in use block, no
Easily cleaning or maintenance, and provide a kind of strake heat exchanger, the utility model by the way that spiral-plate heat exchanger is improved, when
Medium can be with turbulization when passing through spiral plate, and heat transfer effect is more preferable, and it is convenient for dismounting and washing, be not susceptible to block.
The purpose of this utility model is achieved by the following measures：A kind of strake heat exchanger, including tubular shell, institute
It is provided with the spiral plate for rolling into cylinder in the housing stated, described spiral plate forms helical duct, on described spiral plate
Even to be welded with branch chapelet, described spiral plate is internally formed cavity, is provided with cavity dimidiation in described cavity
Septum cordis plate, is welded with support ring on described central partition plate, and the half cavity upper and lower ends that are separated by central partition plate are equal
Semicircle shrouding is provided with, the inlet duct and outlet conduit for being passed through helical duct, described entrance are provided with described housing
Pipeline is connected with spiral plate, and described outlet conduit connects with the semicircle shrouding of cavity bottom, and described housing upper end is provided with
Upper cover, housing lower end are provided with low head, and described upper cover and low head are ellipticity, described upper cover and lower envelope
The pipeline connected with cavity is provided with head.
Preferably, the crisscross distribution of branch chapelet on the described each helical layer plate for rolling into tubular, the branch of same file
Chapelet and adjacent columns branch chapelet not in the same horizontal line, and on adjacent layer spiral plate between branch chapelet not in same level
On line.
Preferably, described upper cover, low head are by flange and housing seal, and flange intermediate cryptographic packing is close
Envelope.
Preferably, described upper cover both sides are provided with hoisting ring.
Preferably, described low head bottom is provided with supporting leg.
Preferably, described inlet duct, outlet conduit, the pipeline opening of upper low head pipeline are welded with flange.
The beneficial effects of the utility model are：The utility model is by will install elliptoid upper cover additional with on heat exchanger
End socket, can dismantle heat exchanger and inner passage also disassembling cleaning, internal structure clearly arrange it is regular, it is easy to maintenance, clearly
Wash fast, exchanged especially suitable for toughness, the liquid for having precipitating liquid with liquid, and gas-liquid, steam condensation, spiral board channel
The branch chapelet of interior setting is regular, and flowing forms turbulent flow up and down in passage where heated medium, less scaling, and this spiral
Structure can largely reduce the resistance of fluid, improve heat transfer efficiency.
