At least the top side or side away from the stream of a group of pipe bundles is uniformly sprayed with rinsing liquid. The pipes of a group of pipe bundles are held apart by spacers so that the stream flows over their outer and inner sides. The pipes of a group of pipe bundles are identical and have different adjustment heights. The pipes have such a length that at least when a turbulent flow enters one pipe, a laminar gas stream is formed downstream.

  • Patent number: 7662219
    Abstract: An electrostatic precipitator that can prevent the corrosion of a discharge electrode even if a gas to be treated containing a corrosive mist is treated. In an electrostatic precipitator having a discharge electrode arranged along a flow path of the gas to be treated, a spray nozzle that can spray a water to the upstream side of the discharge electrode is mounted. A wet film is formed on the surface of the discharge electrode with the water sprayed from the spray nozzle. The sprayed water is desirably a water vapor or a water droplet having a particle diameter of less than 10 ?m.

  • Patent number: 7494532
    Abstract: A carrier is used to carry a liquid, and a high voltage is applied between a discharge end of the carrier and an opposed electrode to emit ionized liquid particles. The carrier has a liquid collecting end opposite to the discharge end to feed the steam of the liquid from a steam generator, condensing the liquid therearound, and feeding the condensed liquid to the discharge end. Accordingly, even when the liquid contains cations such as those of Ca and Mg, the steam of the liquid can extremely reduce the content of these impurities, avoiding the precipitation of the impurities at the discharge end of the carrier to assure stable electrostatic atomization.

  • Patent number: 7473298
    Abstract: Charged fine particulate water is provided, which has a nanometer particle size, for example, a particle size of 3 to 100 nm, and contains radicals such as hydroxyl radicals and superoxides. This charged fine particulate water can be generated by applying an electric-field intensity of 700 to 1200 V/mm between a pair of electrodes, while supplying water between the electrodes. By allowing the thus obtained charged fine particulate water to diffuse into an indoor space, it is possible to effectively remove bad odor components/bacteria from the indoor space.

    Abstract: A device designed for the removal of soot dust of fuel oil combustion. The device is based on the two-stage wet-electrostatic dust removal-desulfurization device, with different numbers of layers of the mesh screen being installed in the wet type dust removal-desulfurization device. This device not only has a relatively high efficiency in both of common dust removal and desulfurization, but also can remove the black smoke from fuel oil combustion efficiently with a removal efficiency ?99%, and thus solves the present technical problem in the treatment of in the treatment of soot dust of fuel oil combustion. At the same time, with the advantages of cheaper construction cost and economy, the device of the present invention overcomes the disadvantages of the traditional bag filter process, which is expensive and cannot operate desulfurization simultaneously.

  • Patent number: 7427313
    Abstract: The device according to the invention includes a drip chamber, which is adapted for connecting to the ordinary water mains, a metal plate and a nozzle that is connected to the drip chamber and disposed above the metal plate and a collecting vessel. The object of the drip chamber is to convert the continuous flow of water from the water mains into discrete drops, thus forming a water reservoir in the bottom of the drip chamber, which is electrically insulated from the water supply while the reservoir still receives a constant new supply of water. Water from the reservoir is passed on to the nozzle and sprayed over the steel plate. An impressed voltage on the nozzle and thereby the water attracts the impurities in the air and these will bind to the water and follow it when the water runs down into a collecting vessel, which is subsequently emptied into the house's drainage system.
