Definitions
- the present invention relates to a device for electrostatically collecting particles suspended in a gaseous medium, commonly called electrostatic collector or electrofilter.
- the present invention relates more particularly to such a device comprising an interchangeable electrode.
- Electrostatic or electrofilter collectors commonly referred to by the acronym ESP (Electrostatic Precipitator) are used to collect particles suspended in a gaseous medium, for example ambient air. They thus make it possible to purify the gaseous medium and possibly to analyze the collected particles.
- ESP Electrostatic Precipitator
- An electrostatic collector comprises two electrodes arranged close to each other.
- One of the two electrodes commonly called the discharge electrode, is polarized.
- the other electrode commonly referred to as a counter-electrode or collection electrode, is generally connected to ground.
- a high electric field is induced between the two electrodes under the effect of the potential difference applied between the two electrodes.
- the electric field ionizes the gas volume between the two electrodes, creating a sheath or ring of ionized gas around the discharge electrode. This phenomenon is called corona discharge.
- the gas containing the particles to be separated which is passed between the discharge electrode and the counter electrode then passes through an ion stream and the particles to be separated are ionized in turn. Under the effect of electrostatic forces, the charged particles thus created are attracted by the counter-electrode on which they are collected.
- Discharge electrodes are generally tip-shaped or wire-shaped.
- Electrostatic collectors have a high efficiency, especially for the collection of submicron particles. Nevertheless, their performance decreases as and when they are used because of a change in the surface of the discharge electrode. Roux et al., "Investigation of a new electrostatic sampler for biological concentrating and non-biological aerosol particles", Aerosol Science and Technology, vol. 47, No. 5, p. 463-471, 2013, describes such a phenomenon.
- the discharge electrode is usually carried at very high voltages of several thousand to several tens of thousands of volts, which are dangerous.
- the positioning of the discharge electrode sometimes requires high accuracy.
- the discharge electrode must be able to be maintained in a fixed position relative to the counter-electrode, and this whatever the orientation of the electrostatic collector.
- the present invention aims in particular to solve these problems.
- the present invention relates to an electrostatic collector comprising a collection chamber, delimited by a tubular wall oriented along a first axis, and a support for holding an electrode in the collection chamber and removing an electrode from the collection chamber.
- the first fixing element is intended to electrically connect the electrode to a polarization source (or voltage source).
- the first fixing element is able to extend in the guide at least until the opening.
- the first fastening element comprises a perforated moving part, comprising a cavity intended to receive the electrode, and a return means.
- the support further comprises a pin which is fixed transversely to the guide and is disposed through the cavity of the perforated part.
- the second fastener may be a push button.
- the first fastener may be a screw.
- An advantage of an electrostatic collector of the type described above is that the electrode can be positioned with high precision in the collection chamber.
- the guide and the perforated part make it possible to maintain the discharge electrode in a vertical orientation in the collection chamber, thanks to three bearing zones.
- the first fastener may be stainless steel.
- the second fastener may be a thermoplastic polymer, for example a material selected from the group consisting of nylon, polyvinylidene fluoride and polyetheretherketone.
- the opening of the guide may have a diameter of between 0.2 mm and
- the present invention also relates to a use of an electrostatic collector comprising a collection chamber, delimited by a tubular wall oriented along a first axis, and a support comprising a guide, traversing transversely the collection chamber, the first and second ends of which are fixed to the wall, the guide having a through opening, whose longitudinal axis is oriented along the first axis, configured to receive an electrode; a first attachment member, having at least one electrically conductive portion, for extending at least partially in the guide, from the first end to the opening; and a second attachment member, having at least one electrically insulating portion, for translational movement in the guide from the second end toward the opening and the opening toward the second end.
- the second attachment member is passed from an open position to a closed position, so as to maintain the electrode in said opening.
- the second attachment member is passed from a closed position to an open position to release the electrode from said opening.
- the electrostatic collector is positioned so that the first axis is oriented vertically.
- the first fastening element extends in the guide at least until the opening.
- the second attachment member is moved to the second end of the guide, and the electrode is positioned through said opening.
- the second fastener is then moved toward the aperture so that the electrode is held between the first and second fasteners.
- the second attachment member is moved toward the second end of the guide so that the second attachment member is not in contact with the electrode.
- the second fastener is moved to the second end of the guide so that the second fastener is not in contact with the first electrode.
- the second electrode is then disposed in said opening in place of the first electrode by pushing the first electrode out of said opening. Then the second fastener is moved to said opening, so that the second electrode is held by the first and second fasteners.
- An advantage of an electrostatic collector of the type described above lies in the fact that an electrode can be handled safely by a user without risk to high voltages. An electrode can be placed in the electrostatic collector, removed from the electrostatic collector or replaced by another electrode safely.
- the first fastening element comprises a perforated moving part, comprising a cavity intended to receive the electrode, and a return means.
- the second attachment member is moved toward the opening to communicate the cavity with the opening, and the electrode is positioned within the opening and at the same time. inside the cavity.

- the first fastening element 22 comprises at least one electrically conductive part.
- the first fastener 22 is for example a metal material, preferably stainless steel. It is able to be connected to a voltage source, not shown. Since the discharge electrode is intended to be polarized at voltages of several thousand to several tens of thousands of volts, the first fixing element 22 is protected, for example by a housing or an insulating housing (not shown), so that the user does not have direct access to this element.
- a protective wall 26 at least partially covers the outer surface of the wall 1 of the collection chamber, on the side of the second end 16 of the guide 13 accessible to the user. This results in enhanced protection of the user against high voltages.
