ELECTRODE SUPPORT FOR AN ELECTROSTATIC PRECIPITATOR APPARATUS AND APPARATUS COMPRISING IT

DESCRIPTIVE MEMORY

TECHNICAL FIELD OF THE INVENTION

The present invention relates to the field of magnetic or electrostatic separation of solid materials from solid materials or fluids, specifically with the separation by electrostatic effect of dispersed particles of gases or vapor and in particular provides an electrode support of an electrostatic precipitator apparatus and an electrostatic precipitator apparatus comprising it.

BACKGROUND OF THE INVENTION

Electric filters or electrostatic precipitators are a solution known in the state of the art to retain contaminating particles. At an industrial level, large precipitators (100 m high or 200 m high) are used to retain particulate emissions from thermoelectric plants or industries that require the burning of biomass for their operation.

Generally, an electrical filter is composed of a main electrode and a discharge electrode. Regarding their shape and arrangement, the electrodes can be flat, concave, or cylindrical.

In the state of the art, multiple documents are known that provide configurations of electrostatic precipitators. For example, JP2916901 B2 discloses an electrostatic precipitator comprising a fan tube and an electrode disposed inside the fan tube and supported from a support member. The support element also electrically connects the electrode to the power supply of the electrostatic precipitator.

Document WO 2006/015503 A1 discloses an electrical filter for a combustion plant comprising an electrode and electrode fixing means that position the electrode in an exhaust gas pipe of the combustion plant. Additionally, particle diversion means are provided to extend filter life.

However, the configurations of the existing electrostatic precipitators in the state of the technique make difficult or impossible its installation and maintenance in existing combustion systems, such as, for example, gas outlet cannons of domestic wood stoves, of the industry, such as mining, refinery, incinerator furnaces and/or any other machine or system, whether a mobile source or stationary source of pollution, that expels exhaust gases and/or polluting particles. On the other hand, those precipitators that have an electrode supported inside a tube or chamber do not allow the supply line of said electrode to be isolated both thermally and electrically.

Therefore, a solution is required that allows overcoming the deficiencies of the state of the art.

In a second object of the present invention, an electrostatic precipitator apparatus is provided, comprising an electrical power source, a first electrode connected to the electrical power source by a first power line, a conductive mantle connected to the electrical power source in a polarity different from that of the first electrode and an electrode support, where the electrode support allows both thermally and electrically to isolate the power line of said electrode and at the same time facilitate its installation and maintenance, which is characterized in that the support electrode comprises: a base having a first lateral end and a second lateral end; a grooved portion disposed in or on the base extending in a longitudinal direction, wherein the grooved portion has at least one first through perforation extending in a first transverse direction; a first projection, positioned at the first lateral end and extending in the first transverse direction; and a second projection, positioned at the second lateral end and extending in the first transverse direction; wherein the support is made of an electrically insulating and refractory material; wherein the conductive mantle extends along the first transverse direction and the electrode holder is positioned at an upper end of the conductive mantle; wherein the first electrode is supported in said at least one first through hole and extends in the first transverse direction; and wherein the first feed line extends, at least partially, along the grooved portion of the electrode holder.

The electrode support (1) (1 10) that is the object of the present invention comprises a base (2) that has a first lateral end (21) and a second lateral end (22). The shape and dimensions of said base (2) do not limit the scope of the present invention as long as said lateral end (21) and second lateral end (22) are present. In a preferred embodiment, the base (2) has an elongated shape and the first lateral end (21) and second lateral end (22) are defined as the ends in the elongated direction of the base. However, in other preferred embodiments, the base (2) may have a regular or irregular polygonal shape in which the first lateral end (21) and the second lateral end (22) can be defined as opposite sides of said polygonal shape.
