    Abstract: PROBLEM TO BE SOLVED: To provide a diesel engine exhaust emission control device for reducing the size of a cyclone and achieving a high PM collection rate and a low fuel cost.SOLUTION: A diesel engine exhaust gas treatment apparatus includes a tubular collection part having a discharge electrode 1-2 for charging particulate matters contained in exhaust gas from a diesel engine using fuel having lower quality than heavy oil and a dust collecting electrode for collecting the charged particulate matters, and a cyclone type classifying collection means for classifying and collecting the particulate matters separated from the tubular collection part. In a high-concentration exhaust gas delivery part for the particulate matters, provided near the inner surface on the downstream side of the tubular collection part, a cyclone collection means 2-1 is provided which is constituted by one or more tangential cyclones. This actualizes such a system that a high-concentration exhaust gas flow exhausted from the high-concentration exhaust gas delivery part is selectively introduced into the tangential cyclones 2-1a depending on the flow amount of the exhaust gas.

    Abstract: An electrostatic precipitator, particularly a WESP, comprising an array of collector tubes and a like array of separately powered discharge electrodes provided in the form of pairs of rods extending within each of the collector tubes. The pairs of rods are provided in the form of a first length rod having a terminal end, the first length rod powered by a first power source, and an axially opposed, second length rod having a terminal end, the second length rod powered by a second power source, wherein each first length discharge electrode rod, of a pair of rods, extends from an inlet of the electrostatic precipitator into a respect e collector tube and each second length discharge electrode rod, of the same pair of rods, extends from an outlet of the electrostatic precipitator into the same, respect e collector tube such that the respective terminal ends of the pairs of discharge electrode rods are spaced apart, thereby defining a gap therebetween. This arrangement enables different energy levels to be applied to each of the first and second length discharge electrode rods of the pairs of discharge electrode rods, by the first and second power supplies, respectively, thereby inducing different levels of ionization within a gas stream flowing through the collector tube array of the electrostatic precipitator, at different locations within the electrostatic precipitator.

    Abstract: The invention relates to a system of cyclones with electrostatically enhanced recirculation, comprising a collector cyclone (Col) with diameter D 1 and an entry for dirty gases (GS), located upstream from a recirculator (Con) with diameter D 2 and a central channel for exhausting the cleaned gases (GL), these cyclones being placed in series and having a recirculation line, from the concentrator to the collector, to recirculate part of the gas stream. It is characterized in that there are means, in the recirculator, for applying a high voltage (AT, ) producing an ionizing electric field that drives the particles away from the central exhaust channel, without any significant particle deposition on the recirculator walls. The current density in the recirculator field is below 0.1 mA/m 2 and the average electric field is below 2xl0 5 V/m. According to the process of the invention, the particles are driven away from the central exhaust channel, in the recirculator, by the joint action of mechanical and electrical forces, these latter deriving from the particles traversing the ionized field, concentrating them in the fraction of the gas stream that is recycled back to the collector cyclone, where a part is captured (P). It is used for dedusting and dry gas cleaning, especially for acid gases, and for capturing bacteria.
