Packing sheet material ethylene propylene diene rubber, heat resisting temperature be 120 DEG C, plate heat exchanger is simple in structure, but with heat transfer process into
Row, the medium of the higher side of pressure seal in the medium of the relatively low side of pressure, the exception of pressure and temperature are will appear in system, such as
Fruit medium has corrosivity, it is also possible to the corrosion of plate heat exchanger gasket seal, gasket seal be caused to be easy to damage and generate
Leakage, heat exchange can not carry out, it is necessary to stop and replace gasket seal, and maintenance, cleaning and the dismounting of plate heat exchanger are all compared
Cumbersome, dismountable place easily causes leakage, seriously affects the normal operation of alkali vaporising device.
Invention content
The utility model provides a kind of heat exchanger suitable for the heat exchange of high/low temperature lye, using heat exchanger with oblate,
The problem of avoiding leakage and liquid leakage, and segmental baffle is eliminated, there is no heat exchanging corner in shell-side flow path, improves heat exchange
Area utilization reduces the resistance of shell-side flow path.
In order to achieve the above object, the utility model uses following scheme：
A kind of heat exchanger suitable for the heat exchange of high/low temperature lye, including low temperature lye import 6, low temperature lye export 7, high temperature
Lye import 8, high temperature alkaline solution outlet 9, spiral flat tube heat exchanger tube 10, bundled fixed band 11, upper cover 12, low head 13, shell
14；12 top of upper cover connects low temperature lye export 7, and 13 bottom end of low head connects low temperature lye import 6, and outermost layer is shell
14, for shell 14 close to 12 one end of upper cover connection high temperature alkaline solution import 8, shell 14 connects high temperature alkaline solution close to 13 one end of low head
Outlet 9, the interior installation spiral flat tube heat exchanger tube 10 of shell 14, low temperature lye import 6 connect 10 lower end of spiral flat tube heat exchanger tube, low temperature
Lye export 7 connects 10 upper end of spiral flat tube heat exchanger tube, low temperature lye by spiral flat tube heat exchanger tube 10 inside, high temperature alkaline solution is logical
It crosses outside spiral flat tube heat exchanger tube 10.
Spiral flat tube heat exchanger tube 10 described above is fixed by bundled fixed band 11, and the section of spiral flat tube heat exchanger tube is flat
Flat circular cross-section, i.e. cross sectional shape are made of two parallel lines and two semi arches, while flat straight section length is straight equal to circular arc
Diameter, whole heat exchanger tube are spiral-shaped, lead of screw 350mm, and the channel in spiral flat tube heat exchanger tube 10 is that a spiral is logical
Road.
The beneficial effects of the utility model：The utility model provides a kind of heat exchange suitable for the heat exchange of high/low temperature lye
Device, using heat exchanger with oblate, the problem of avoiding leakage and liquid leakage, low temperature lye is from low head into upper cover goes out, and high
Warm lye is then to be brought out from the upper end of shell under, and low temperature lye and high temperature alkaline solution form adverse current in heat exchanger with oblate and change
Heat, since the runner of heat exchanger with oblate shell side and tube side is all helical flow path, lye can week during countercurrent flow
Change speed and direction to phase property, so the helical flow path that low temperature lye passes through shell side by the helical flow path and high temperature alkaline solution of tube side
When all increase the turbulivity of itself, longitudinal mixing well can be formed, destroy the fluid boundary layer on tube wall, enhancing is entire
The heat transfer efficiency of heat exchanger；Heat-exchanging tube bundle in heat exchanger with oblate is that bundled fixed brings fixation, is not had in heat-exchanging tube bundle
Baffle plate, point contact at long axis in adjacent heat exchange tube section form helical flow path at short axle, and heat exchanger with oblate is cancelled
The analysis of arch baffling does not have heat exchanging corner in shell-side flow path, improves heat exchange area utilization rate, just improve the effect of heat exchange yet
Rate, while the resistance of shell-side flow path is reduced again.
