Definitions

  • the present invention relates to a device for separating materials in the form of particles and/or drops from a gas flow. Further, the present invention relates to a method for separating materials in the form of particles and/or drops from a gas flow.
  • filters, cyclones, or electrical methods are used in gas purification systems and for separating particles from a gas flow.
  • Methods and devices for separating particles or drops from a gas flow are e.g. known from DE 1471620 A1 and DE 19751984 A1 .
  • Air purifiers that are currently being used have moved away from the conventional method of using filters in order to mechanically extract unwanted particles from air.
  • Such conventional filtration systems suffer from the disadvantages that the air flow has to be limited to a slow flow stream and that the filter has to be periodically removed for cleaning.
  • the operation of the cyclones is based on the decrease in the gas flow speed so that the heavy particles in the gas flow fall down into the collection organ. Cyclones are thus applicable for separating heavy particles.
  • electric air purifiers exploit the properties of charges in ionised gas and use electrostatic means to extract the charged particles from a directed airflow. This method of extraction improves efficiency not only in terms of overall amount of particles being extracted but also the types of particles.
  • An air purifier would typically exploit the properties of positively or negatively charged particles where an electric field would interact with these charged particles. The charged particles would respond to the electric field and be pulled towards the ion blow onto a collection surface.
  • Document EP 1165241 B1 discloses a method and device for separating materials in the form of particles and/or drops from a gas flow, in which method the gas flow is directed through a collection chamber the outer walls of which are grounded, and in which high tension is directed to the ion yield tips arranged in the collection chamber, thus providing an ion flow from the ion yield tips towards the collection surface, separating the desired materials from the gas flow. It is characteristic of the invention that the collection surface conducting electricity are electrically insulated from the outer casings, and that high tension with the opposite sign of direct voltage as the high tension directed to the ion yield tips is directed to the collection surface.
  • the electrical insulation is made of ABS
  • the surface conducting electricity comprises a thin chrome layer arranged on the insulation layer.
  • the ion yield tips are arranged in rings, with the help of which the distance between the ion yield tips and the collection surface is made shorter. Thus, some particles contained in the slow gas flow do not pass through the ion beams, but instead between the fastening rod and the ion yield tips.
  • Document US 2003/061934 A1 describes a method to clean air for separating materials in the form of particles and/or droplets from a gas flow.
  • the gas flow is directed through a collection chamber in which the outer walls are grounded, and in which high voltage is supplied to the ion yield tips arranged in the collection chamber.
  • an ion beam from the ion yield tips towards collection surfaces is established to separate desired material from the gas flow.
  • the electrically conductive collection surfaces are electrically insulated from the outer castings and high voltage is supplied to the collecting surfaces, in which the direct-current voltage has an opposite sign as the high voltage directed to the ion yield tips.
  • a device for separating materials in the form of particles and/or drops from a gas flow comprising an inlet for incoming air to be purified, a collection chamber, an outlet for the purified air, a voltage source, a fastening column to which ion yield tips have been coupled, the device is configured to direct high tension to the ion yield tips providing ion beams from the ion yield tips to the collection surface, the collection surface conducting electricity is electrically insulated from the outer wall of the collection chamber by an electrical insulation, and the device is configured to direct voltage of opposite sign to the ion yield tips than the voltage directed to the collection surface, wherein the ion yield tips are arranged directly on a surface of the fastening column having a length, wherein the ion yield tips protrude from the surface of the fastening column into a cavity of the collection chamber, wherein a diameter of a cylindrical fastening column is in a range between 40 - 150 mm and a maximum

  • a system and a method of separating materials in the form of particles and/or drops from a gas flow are provided.
  • separation of materials from a gas flow can be further improved.
  • a high reduction efficiency can be achieved.
  • a device according to certain embodiments of the invention using a fastening column with a diameter of 100 mm, using a voltage of 60 kV and using a current of 1400 ⁇ A has provided an excellent reduction efficiency, for example for particles having a size of greater than 50-200 nm.
  • the reduction efficiency can be improved from about 70 % to about 80 % by means of certain embodiments of the invention.
  • a suitable amount of ion yield tips can be arranged directly on the surface of the fastening column.
  • the gas flow is exposed to an electric field in the cavity between the ion yield tips and the collection surface and all of the material contained in the gas flows through the cavity. There is no gas flow through rings outside the electric field.
  • the reduction efficiency can be also improved for particles and/or drops the diameter of which varies from one nanometer to 10 nanometers or to 20 nanometers or to a few dozen nanometers.
  • the system according to certain embodiments of the invention also improves the reduction efficiency of particles and/or drops with a diameter of less than 10 nanometers.
  • the present invention relates to a device for separating materials in the form of particles and/or drops from a gas flow, the device comprising a chamber arranged within a housing providing an inlet and an outlet for an air flow.
  • the housing provides a surface which serves as a collection surface.
  • a column Inside the housing substantially at the centre is provided a column with a cylindrical or elliptical body.
  • a series of ion yield tips is arranged for directing ion beams to the collection surface.
  • the column is connected to a power supply that allows the ion yield tips to generate electric fields in the form of ion beams emanating from the ion yield tips.
  • the housing and the column are isolated from each other and they can be connected to separate power supplies so that they possess different charges for the purpose of directing the electric fields.
  • the column is typically at least partially a cylindrical body that has a surface defined by the diameter in its cross section and the length of the body.
  • the dimensions of the column define the cross sectional area of a cavity between the column and the collection surface.
  • the local velocity of the air flow in the cavity can be increased by increasing the diameter of the column.
  • the larger the surface area the more ion yield tips can be arranged on the body, thereby increasing the electric field and current generated encapsulating the body. This allows greater exposure of the electric field for the particles contained in the air flow to be charged and then directed to the collection surface for removal.
  • the high density of the electric field created inside the chamber improves the efficiency of extraction of the particles by extracting more particles from a fast flow of air. Furthermore, all particles included in the air flow have to pass through the cavity between the column and the collection surface.

  • the electrical insulation may be glass, plastic, acrylic-nitrile-butadiene-styrene (ABS), or some other similar substance insulating high tension, for instance.
  • the device 1 is configured to direct voltage of opposite sign to the ion yield tips 10 than the voltage directed to the collection surface 12.
  • voltage with the opposite sign of direct voltage (positive in the figure) as the high tension directed to the ion yield tips 10 (negative in the figure) is directed to the surface 12 conducting electricity.
  • the voltages are opposite, i.e. positive for the ion yield tips 10 and negative for the surface 12 conducting electricity, or negative for the ion producing tips 10 and positive for the surface 12 conducting electricity.
  • the voltage of the ion yield tips 10 is substantially equal to that of the collection surface 12, but it is also possible to use voltages of different magnitude.
