For a less demanding, lower throughput gas cleaning system, the venturi scrubber is a well tested and respected design used by many industrial processes. It uses a combination of vortex technology and high pressure water misting to remove harmful elements from the exhaust gases.
Our incinerators are designed to ensure Dioxins, furans and similar gaseous components are destroyed using homogeneous high temperature (> 850°C), ensuring there is an excess of oxygen (>6 %) and sufficient residence time at high temperatures to make sure all 3 conditions are met.
If the three conditions above are not met, dioxins will "crack" into smaller but reactive dioxins, which can reform into new dioxin molecules, especially in the presence of heavy metals which can act as catalysts. (Reformation and "de novo" formation).
Through a combination of R&D and CFD modeling we have enhanced our venturi to incorporate a new spray head that has been optimally designed to cope with the demands of operating continuously within a waste sector. The atomized liquid provides an enormous number of tiny droplets for the dust particles to impact on. These liquid droplets incorporating the particles must be removed from the scrubber outlet stream.
Gas scrubbers are very effective at removing noxious gases, particles, odours, fumes and dust from gas streams.
The overall process is quite straight forward - the key to successful operation is ensuring there is a continual flow of air and water made available to the venturi scrubber.
As the gas stream is introduced into a scrubber box, it is forced to pass through a converging section, where (in accordance with Bernoulli equation) gas stream velocity is rapidly increased. The throat section between pipes is where particle and gas removal occur as the inlet gas stream mixes with the fog of tiny liquid droplets.
