Problems solved by technology

[0004] This arrangement is completely satisfactory, but it can happen that particles such as charged soot particles can deposit on the insulator, especially at the location of the end disks, forming a layer of soot that leads to arcing, which reduces the filtration effectiveness of the device, and sometimes the need to stop the device

Embodiment Construction

[0072] as Figure 1 to Figure 10 The purifying device 10 for purifying a particle-laden gaseous medium, which is the subject of an embodiment in the present invention, is used for purifying exhaust gases of an internal combustion engine.

[0073] The purification device is shown very diagrammatically in some of the figures in order to reveal its characteristic components.

[0074] In particular, this purification device 10 comprises a longitudinal housing 11 in which is housed a corona-effect electric filter, the working principle of which is known in the prior art, in particular in patent application WO01 / 19525 is known.

[0075] Such as figure 1 As shown, the housing 11 is closed at its ends by end plates. The end plates are here made of (also figure 2 , image 3 , Figure 7 and Figure 8 The end disc 31 and the ring 13 of the cylindrical part 30 shown in .

[0076] Two diametrically opposite openings 14 and 15 are formed in the housing 11 to enable gas to enter an...

Abstract

The invention relates to a device for purifying a gaseous medium loaded with particles comprising a shell (11) closed at the ends thereof by an end plate (31) protected by a disjoined shell (70), an electrostatic filtration chamber (20) having a passage for the gaseous medium loaded with particles; said chamber (20) comprising an emissive structure (40) comprising serrated plates (42) forming tips(47) directed towards a collecting structure (50) on either side of said emissive structure (40) and designed to trap the particles contained in the gaseous medium; said end plate (31) and said shell(70) are each brought to a different predetermined potential so as to create an electric repulsion field in the vicinity of said end plate (31), directed towards said passage.

Description

technical field [0001] The application relates to a device for purifying gaseous media laden with various particles, such as dust particles, organic particles suspended in various exhaust gases, especially from industrial boilers, chimneys where industrial furnaces are installed, diesel Exhaust gas from engines, etc. Background technique [0002] The applicant has proposed a device of this type for purifying particle-laden gaseous media, more particularly for the exhaust gases of internal combustion engines (see in particular patent application WO 01 / 19525). [0003] The treatment device comprises a corona effect electric filter or electrofilter comprising: a cylindrical longitudinal housing in which a longitudinal channel for the treatment gas extends; A central longitudinally extending emitter structure of the channel; and a longitudinally extending collection structure (formed of stainless steel mesh, designated as a cartridge) between the channel and the housing and com...
