Photo reactions in industrial scale<br />
Picture: Ekato<br />
The agitated photo reactor by<br />
Ekato was designed <strong>for</strong> multiphase<br />
reactions with liquids,<br />
gases and solids. The reactor is<br />
available in sizes up to 50 m 3<br />
and beyond. As light sources,<br />
mercury lamps or LED are positioned<br />
inside a quartz glass<br />
tube. Between 4 and 20 tubes<br />
are submerged into <strong>the</strong> reaction<br />
mass, passed through nozzles in<br />
<strong>the</strong> tank head, where <strong>the</strong>y connect<br />
to <strong>the</strong> power supply and<br />
<strong>the</strong> cooling medium. Cooling is<br />
necessary to prevent high surface<br />
temperatures of <strong>the</strong> tubes,<br />
which might damage <strong>the</strong> product.<br />
The agitator has to provide<br />
high pumping rates and <strong>the</strong>reby<br />
a permanent renewal of <strong>the</strong><br />
reactants in <strong>the</strong> irradiation zone.<br />
For reactions with gases,<br />
bubbles are efficiently dispersed<br />
to ensure high conversion rates.<br />
With suspensions, agitation facilitates<br />
heat removal during<br />
reaction. Sealing of <strong>the</strong> agitator<br />
shaft towards <strong>the</strong> atmosphere is<br />
obtained by double or triple<br />
acting mechanical seals or by<br />
using hermetic magnetic drives.<br />

Flexible tripod agitators<br />
Picture: Geppert<br />
Geppert offers complete tripod<br />
agitators, equipped with up-to<br />
date process control. These machines<br />
offer flexibility of application<br />
and are easy to clean and<br />
maintain. Due to <strong>the</strong> tripod agitators’<br />
stand-alone statics <strong>the</strong>y<br />
may be applied with various<br />
container sizes, shapes or volumes.<br />
Data aquisition and processing<br />
make even online viscosity<br />
measurements possible.<br />
For special requirements arising<br />
from <strong>the</strong> product or <strong>the</strong> production<br />
area, tailor-made versions<br />
of <strong>the</strong> tripod agitators are available.<br />
So <strong>the</strong> devices can be<br />
delivered as explosion-proof<br />
models according to Atex RL<br />
2014/34/EU <strong>for</strong> use in hazardous<br />
zones 1 and 2 as well as<br />
containers with zones 0 to 1. In<br />
addition, special designs like tripod<br />
agitators <strong>for</strong> fixed container<br />
mixers or fully automated<br />
plants, which are used in clean<br />
rooms or areas of nuclear waste<br />
processing, complete <strong>the</strong> product<br />
range.<br />
