Droplet separators in wet scrubbers
Since the introduction of new limit values for the sulphur content of fuels in the Emission Control Area (ECA) on most ships, it has become necessary to retrofit an exhaust gas purification system. The protected areas will be extended to the whole world from 2020. For wet scrubbers, vertical separators are used.

Droplet separators for vertical gas flow
In vane-type separators with vertical gas flow, the baffle vanes are arranged horizontally or at a slight horizontal angle. The liquid that is separated at the profile forms a film which drains downwards in the opposite direction to the gas flow. This liquid film interacts with the opposing gas flow. At the bottom end, larger droplets are formed from the liquid film which then fall down.
Reliable operation – even under tough conditions
Lechler droplet separators are characterized by the optimized-flow design. However, if the gas flows are heavily loaded with dust, deposits can occur under unfavorable conditions which impair the efficiency of the droplet separators. In this case, an additional cleaning system helps to guarantee availability during continuous operation. An arrangement that performs cyclical washing of the droplet separators with full-cone nozzles has proven particularly suitable for this. This allows you to increase functional reliability, avoid encrustations and also ensure that your plant operates with optimum efficiency over long periods.
