Gas cleaning (scrubbing)
Customized gas cleaning solutions for spray applications in scrubbers
Efficient gas cleaning is essential for protecting the environment and reducing harmful emissions. At Lechler, we have extensive expertise and know exactly how and where droplets need to be introduced and precisely separated in the gas cleaning process. This is the only way to ensure an efficient gas cleaning process and achieve the maximum cleaning effect.
Many control variables for maximum scrubbing efficiency
Lechler is the only company to offer a complete portfolio of nozzles and droplet separators. Comprehensive services from engineering services to complex flow simulations complete our offer for gas cleaning applications. This is why Lechler is the preferred partner for spray applications in scrubbers.

Scrubber types
Different scrubber types are recommended depending on the application. The nozzle selection and positioning are selected for their efficiency. Here, Lechler does not just provide support as a supplier but also assists with its extensive experience in the planning and design of scrubbers.
Spray scrubber
Spray scrubbers atomize the washing liquid by means of several spray nozzles and generate a large reactive surface area. They are characterized by lower installation and maintenance costs as well as lower pressure losses.
Venturi scrubber
With this special form of a spray scrubber, the gas is routed through a narrow section into which the washing liquid is injected. Dirt particles are effectively separated due to higher flow velocity. Venturi scrubbers require less washing liquid than conventional spray scrubbers but are less effective for the separation of smaller particles.
Packed-bed scrubber
With packed-bed scrubbers, the gas is routed through packing material whose large surface area is wetted with the washing fluid. This scrubber type removes pollutants very effectively but requires a lot of space and maintenance. High pressure losses have to be taken into account in calculations due to the design principle. Clogging may also occur.
