Electrostatic precipitator with across the Gr

It is a known fact that behind the electrostatic precipitator there are xm HestäaubgeiJalt the 0-ace suspended particles _? Despite their static charge, which they absorbed in the force field ρ did not reach the precipitation electrode, they could partially settle behind the electrode system, insofar as they come into contact with opposing constructional parts, on the filter and pipe walls .

The subject of the present invention is to evaluate this knowledge in a useful manner. It proposes _s behind the force field and in multi-stage electric filters behind each force field additional to provide as iliedersehlagselektroden serving internals _P can pass the perforated from individual with Ibstand each other arranged strips or panels oriented transversely to the gas flow, and for example, are connected to ground _o These additional j Hiederschlagselektroden? / erdea liiatereinancler arranged so that the dust particles carried zoom necessarily to them are 'and adhere there to a large extent remain <= Bs are two or more liederschlagselektrodsn forgeseh en _{wherein the DurchgaagsöffHTjagea offset from one another τι®χδ.®ϊϊ Waue jgs Ibst- anö is so small that there is no lamellar flow aiiiibiidtss IisüDo the Sase

In this way, a considerable improvement in the filter efficiency _L wheel is achieved with relatively little effort.

In the embodiment according to FIGS. 4 and 5, it can be expedient be the holes of the various panels by at least the wall thickness to make the collar different sizes. In this way you get a good stacking option, since the collars are smaller Holes in the collar of the larger holes can engage.
