Waste heat recovery system
Spiral plate heat exchanger is composed of two rolled steel plates
which form two uniform spiral channels where two heat transfer
media can realize a full countercurrent flow and thus substantially
enhance heat exchange effect. The connecting tube on the crust is
of shear structure and featured by small local resistance. As the
curvature of spiral channels is uniform, there is no great steering
of fluid flow in the equipment. The total resistance is small. So
it is possible to make the equipment possess fairly high heat
transfer capacity through raising the designed flow rate.
Appropriate technical calculation should be conducted at the time
of equipment selection to make the media in channels reach
turbulence state. (The flow rate of fluid is greater than 1m/s and
that of gas is greater than 10m/s in general.)
Spiral plate heat exchanger Features:
1>. High heat transfer efficiency: The heat transfer efficiency
of spiral plate heat exchanger is 1-3 times as much as that of
shell-and-tube heat exchanger.
The maximum heat transfer coefficient is up to 3,300W/(k).
2>. Effective recovery of low-temperature heat energy: Two heat
transfer media in the equipment can realize heat transfer through a
full countercurrent flow,being applicable to heat transfer with
small temperature difference, recovery of waste heat, and full
application of low-temperature heat energy.
3>. Strong operating reliability: The two non-removable channels
are welded for sealing, which can ensure that the two media are not
mixed together.
4>. Small resistance: Spiral plate heat exchanger can process
large-volume steam or gas with fairly small pressure loss. It has a
self-cleansing ability, for the media flow spirally and results in
remote possibility for dirt deposition. It can be easily cleaned
with steam or lye and allows for installation of cleaning device.
As the medium flows in a single channel, and the allowed flow rate
is higher than that of other kinds of heat exchangers.
Application:
1>.Electrolyte heating
2>.Concentrated lye cooling
3>.Quenching oil cooling
4>.Oleum cooling
5>. Fatty acid cooling
6>.Steam condensation

Working principle
The wet air enter into the heating area from the bottom of the equipment.
After the bottom of hot pipe absorb the heat, and the working medium in the hot pipe will be evaporated, and absorb Evaporated heat from the wet air . after evaporation , the steam will go up to the top of the hot air , meanwhile , it can be pre-condensed ,and release the potential heat to the hot air radiating area . and the condense will back return by the gravity heavy , and continuously receive heat , and repeat delivering the heat from the heating area to the heat radiating area,and heat the fresh for waste heat recovery .
