In fields of application which are unsuitable for fabric filters Riedel Venturi Scrubbers HNA or absorption scrubbers are used, especially in case of:
- moist exhaust air flows with a risk of condensation
- sticky and oily dusts
- ignitable dusts
- portions of gas in the exhaust air
Riedel Venturi Scrubbers embed particles in smallest water droplets and separate them together with the water droplets. So fine particles of far below 10 µm can easily be separated.
Venturi scrubbers consist of the following components:
- Centrifugal drop separator
- Sludge discharge or water treatment system respectively
Inside intent Venturi the water is finley atomized and the dust is embedded in water droplets. In the downstream centrifugal separator the water droplets are deposited with the dust.
The muddy water is either led to a central water treatment or is decentrally cleaned by systems located behind the venturi scrubber.
Our scrubber systems are optimized in respect of maintenance and sewage water treatment. If possible the water is circulated.
Riedel absorption scrubbers are used for the separation of gases from the exhaust air flow. A washing agent which is selected in dependence on the gas to be deposited is finely atomized and passed through a packed bed. Thus a large material exchange surface is created for an efficient cleaning of the exhaust air.
The washing agent is to be renewed at regular intervals.
