Stainless Steel Air Cooled Heat Exchanger For Ethanol Purification
The air-cooled heat exchanger is a device that uses ambient air as
the cooling medium and sweeps the outside of the finned tube to
cool or condense the high-temperature process fluid in the tube.
The air cooler is mainly composed of five basic components: tube
bundles, fans, frames, shutters and ladder platforms composition.
The air cooler uses natural air as the cooling medium, which saves
valuable water resources, reduces the discharge of industrial
sewage, and protects the natural environment.
Especially in industries such as coal-carbon chemical industry and
thermal power plants, air-cooled substitution has greater cost and
environmental advantages than other heat exchange methods.
1. Induced wind type:
The tube bundle is located on the suction side of the fan. Because
the wind tube has a good function of blocking sunlight, wind, rain
and snow on the heat exchange fin tube, the induced-draft air
cooler has a relatively stable heat exchange performance.
At the same time, it has the characteristics of uniform air
distribution, less thermal cycle, less pollution and low noise.
2. Blowing type:
The tube bundle is located on the exhaust side of the fan. This
structure is very convenient for maintenance, and the fan motor is
always in a cooler air environment, which allows the device to
process higher temperature process media, thereby maintaining a
longer service life.
3. Inclined top air cooler:
The tube bundle can be placed in a herringbone shape, with a
compact structure and a small footprint, which is about 40% of the
horizontal; but the distribution of the medium in the tube and the
air outside the tube is not even enough, and it is easy to form a
hot air recirculation; it can realize an antifreeze structure,
which is especially suitable for steam turbines. Exhausted steam
It is widely used in petrochemical, traditional coal chemical, new
coal chemical, food, dairy, cold storage, beer, medicine, coal and
