摘要： ESP particle collector (1) for collecting particles in a particle containing gas stream, comprising an inlet section (4), a collector section (6), and an electrode arrangement (8), the inlet section comprising a flow tube (10) defining a gas flow channel (12) therein bounded by a guide wall (24) extending between an entry end (14) and a collector end (16) that serves as an inlet to the collector section (6), the entry end comprising an inlet (28) for the particle gas stream and a sheath flow inlet portion (26) for generating a sheath flow around the particle gas stream, the collector section comprising a housing (18) coupled to the flow tube, and a collector plate (20) mounted therein having a particle collection surface (23). The ESP particle collector is configured to allow optical analysis of the collector plate particle collection surface to measure particles collected thereon. The electrode arrangement comprises at least a base electrode (8a) positioned below the collection surface and a counter-base electrode (8b) positioned at a separation distance L2 above the collection surface such that an electrical field is generated between the electrodes configured to precipitate said particles on the collection surface, wherein the electric field is in a range of 0.1 kV per mm to 1.5 kV per mm, with an absolute voltage on any said electrode that is less than 10 kV, and wherein a ratio ratio I of a radius L1 of said inlet at the collector end divided by said separation distance L2 is in a range of 0.8 to 1.2.

摘要： Apparatuses and methods for selectively transmitting objects of interest from a first reservoir to a second reservoir are disclosed. The apparatuses include electromagnetic focusing apparatuses configured to interact with objects of interest to induce a change in a property of the objects of interest so as to increase or decrease the probability that the objects of interest pass through a throat diffusively coupling the first reservoir and the second reservoir.

The electrostatic dust collection apparatus of the invention includes a sheet collection electrode, an insulative bearing member and a plurality of discharge electrodes. A first surface of the sheet collection electrode faces and is parallel to a second surface of the insulative bearing member. A plurality of grooves are formed on and across the second surface of the insulative bearing member, and are parallel to one another. Each discharge electrode corresponds to one of the grooves, and is disposed in the corresponding groove. An air passage is defined between the sheet collection electrode and the insulative bearing member, and allows an air to be treated to pass through. The discharge electrodes charge a plurality of floating particles in the air to be treated. The sheet collection electrode collects the charged particles.

摘要： A particle sensor comprises an electrostatic particle charging section and a parallel-plate particle precipitation section, and a sensor for detecting the precipitated particles to produce a sensor signal. A pre-filter is placed upstream from the particle charging section. The pre-filter characteristics are such that the sensor signal in response to entrained particles which are not filtered out by the pre-filter relates to the apparent particle number concentration Napp of the particles entering the particle sensor by a calibration constant S which is less dependent on the count mean particle diameter dp,av of the particles entering the particle sensor than the dependence on dp,av that exists in the absence of the pre-filter. Thus, the dependency of the sensor signal derived from the particle deposition in the parallel-plate precipitation section on the particle size distribution (caused by incomplete particle deposition in the precipitation section) is at least partly compensated for by a pre-filter which has a suitable dependency of its filtering function on the particle size.

The system includes a vessel and an electrostatic collector mounted within the vessel which electrostatically removes contaminants from contaminated working fluid as it passes through the electrostatic collector element. The electrostatic collector element includes a plurality of concentric electrodes of different radii, a plurality of corrugated walls residing in spaces located between adjacent electrodes. An elongated center post electrode is provided that induces a voltage in at least one of the plurality of concentric electrodes. The system is configured to generate a voltage difference between each pair of adjacent concentric electrodes to electrostatically remove contaminants from the working fluid as it flows through the filtration and separation system. The system further includes a center post isolator that is configured to mount the center post isolator within the vessel and electrically insulate the center post electrode from the vessel.

摘要： A particle collector system includes a dust collection unit, a power source unit, and a capacitance measurement unit. The dust collection unit includes first and second electrodes, a second electrode, and a dielectric body covering the electrodes. The power source unit supplies power source voltage to the first and second electrodes. The capacitance measurement unit measures the capacitance between the first and second electrodes. With this particle collector system and dust collection method using it, particles can be almost completely removed without periodic performance of a particle removal operation.
