A system for the purification of the particulate present in fumes and in exhaust gases in combustion processes, comprising an Ionizing Part (PI) and a Collection Part (PR), wherein the Ionizing Part (PI) comprises a perforated portion (40, 50) with at least one electron emitter inside the holes (42, 52) consisting of one or more tips (P) to which a high negative voltage is applied to create an electron cloud, wherein said negative supply is provided by a constant voltage generator, in which the fumes and exhaust gases are passed through the Ionizing Part (PI) to transfer a negative charge to the particles of particulate present in the flow of the fumes and exhaust gases, and wherein the Collection Part (PR) comprises a plurality of metal pipes (20) positively charged to collect the particles of particulate previously negatively charged.

The invention provides an integrated separator system for the preconcentration of a material comprising one or more grizzly bars and one or more electrodes which provide a high voltage pulse (HVP) discharge to the material. The invention also provides a process for preconcentration of a material preferably a mineral within a rock which comprises: providing the material into an integrated separator system comprising one or more grizzly bars and one or more electrodes which are capable of providing at least one high voltage pulse discharge(s) to the material; applying one or more high voltage pulse discharge(s) to the material as the material is travelling along the grizzly bar(s) to preferentially disintegrate the particles containing mineral grains of high conductivity/permittivity; separating the disintegrated particles by way of the grizzly bar(s) resulting in the separation of the feed material into low grade (oversize) and high grade (undersize) products; and wherein the disintegrated particles from step b) pass through a screening element for further treatment. The present invention also relates to a process for comminution of a material.

An air-conditioning apparatus including an electrical precipitator part that has an electric discharge electrode having a body portion and corona discharge portions being for corona discharge and protruding from the body portion, and a collecting electrode that is provided opposite the electric discharge electrode, and an medium-efficiency particulate air filter part that is provided downstream of the electrical precipitator part , wherein the collecting electrode is a plate-shaped member, a plate surface thereof is provided parallel to a gas flow direction, and the corona discharge portion has a first corona discharge section that protrudes from the body portion at one side end of the body portion, upstream in the gas flow direction, and a second corona discharge section that protrudes from the body portion at the other side end of the body portion, downstream in the gas flow direction.

Precipitator unit of a two-stage electro filter where air to be cleaned from electrically charged particles is intended to flow through the unit. Said unit comprising at least two cylindrical precipitators (10, 11) that each comprise at least two electrode elements arranged at a gap distance from each other. Each one of the precipitators (10, 11) is also intended to be connected to a high voltage source. The respective electrode elements of a precipitator (10, 11) are connected to different poles of the high voltage source. The main planes of the precipitators (10, 11) are axially spaced in the air flow direction and a cone shaped duct (21) extends between the circumference of the first precipitator (10) and a center opening (13) of the second precipitator (11). A first amount of polluted air flows across the area of the first precipitator (10) and continues afterwards through the inside of the cone shaped duct (21) and out of the unit through the center opening (13) of the second precipitator (11). A second amount of polluted air flows outside the circumference of both the first precipitator (10) and the cone shaped duct (21) in order to be cleaned by the second precipitator (11).

Easy-Air (-) Ion Generator: The present invention provides an electric device that creates ‘corona discharge’ for cleaning the air from airborne/atmospheric particulate matter including gaseous and biological contaminates. The invention uses high voltage DC current that performs two functions/phases: (1) The first function has two pairs of positive and negative polarity, therein for building a force field between the metal plates for attracting airborne particles, gaseous and biological contaminates that are incinerated. SEE FIG. #1. (2) The second function has negative current wires that goes across the force field, which comes into contact with the filtered air separating negative ions that flow into the room or local area. SEE FIG. #2. The negative ions attach themselves to any particulate matter including soot, tobacco smoke, smog, oil smoke, fly ash, cement dust, suspended atmospheric dust, settling dust, and heavy dust and with its increased molecular weight and pulls the particulate matter to the ground or surface reducing/related atmospheric particulate matter to enhance air quality. Any related airborne/atmospheric particles with a heavier molecular weight due to the negative ionization process are also attracted to the positive current force field and are re-filtered to enhance air quality. SEE FIG. #1. Additionally, the corona discharge is used to split the diatomic oxygen molecule into valent oxygen atoms. These oxygen atoms have a negative charge and will bond quickly with another oxygen molecule to produce ozone. For each split oxygen molecule 2 ozone molecules are produced. SEE FIG. #2.

Provided is a solvent separation method and a solvent separation apparatus in which a vaporized solvent is collected at one internal side of a solvent separation unit by attracting the vaporized solvent based on electric field, while the vaporized solvent is prevented from coming into contact with electrodes, and the collected solvent is discharged from the solvent separation unit. Different electric fields are alternately applied to a pair of first electrodes and a pair of second electrodes present at predetermined locations inside a tetragonal tubular solvent separation unit to attract a vaporized solvent toward the second electrodes. Thus, the vaporized solvent is collected in a space between the second electrodes inside the solvent separation unit, and the collected solvent is discharged from the solvent separation unit, together with a portion of the exhaust atmosphere present around the collected solvent.
