Example Embodiment
[0049] Referring to FIG. 1, the gas cleaning device 500 may include a particle charging unit 150, a flow guiding structure 30 and a particle collector 10.
[0050] The particulate gas FG may be introduced into the gas cleaning device 500 via the gas inlet duct 301.
[0051] The particle charging unit 150 is configured to form charged particles P1 by charging the neutral particles P0 of the particle-charged airflow FG. The particulate gas FG can be, for example, flue gas from a combustion process.
[0052] The particles P0 may be solid or liquid particles, for example. The diameter of the particle P0 may, for example, be in the range of 5 nm to 500 nm.
[0053] The charging unit 150 may include an ion source 100 and an intake duct 301. The ion source 100 is configured to provide a flow of ionized gas IG. The ionized gas IG includes ion J1, such as Figure 1a The black dots are shown.
[0054] The ionized gas IG may be introduced into the intake duct 301 via the nozzle 130. The subst...
