Definitions

  • the invention relates to a plastic pipe for wet electrostatic precipitator and a kit for an emission control system.
  • wet electrostatic precipitators are preferably used for industrial waste gas purification, when dry exhaust gas cleaning is only possible to a limited extent and cooling and condensation of the waste gases are required for environmental reasons.
  • wet electrostatic precipitators are used when solid particles in the exhaust gas stream are to be mixed with a liquid or when the recovery of solvent-containing substances is prescribed by legislation.
  • gas scrubbers upstream or downstream of the wet electrostatic precipitator are so-called cyclone scrubbers, dynamic scrubbers or venturi scrubbers or rotary scrubbers or absorption scrubbers.
  • the particles bound in the liquid are collected in a settling tank or a so-called thickening tank, and then the treated and clarified water is returned to the wet electrostatic precipitator.
  • a settling tank or a so-called thickening tank By this cleaning process, microscopic particles smaller than 2 ⁇ m in size can be removed from the exhaust gas flow with high efficiency and the continuous water spraying reduces the particle deposition / accumulation on the inner surface of the wet electrostatic precipitators.
  • the exhaust gas separation performance of a wet electrostatic precipitator system is essentially determined by the physicochemical properties of the exhaust gas particles present in the exhaust gas stream, their composition and by the respective dielectric constants of the exhaust gas particles, ie their electrical behavior in the electric field.
  • tubular or honeycomb wet electrostatic filters currently in use also permit the separation / separation of quasi-sticky, liquid or solid particles of different sizes from an exhaust gas flow.
  • wet electrostatic precipitators high technical requirements in terms of chemical and thermal resistance and resistance to a high voltage field and thus possible electrical flashovers are made.
  • bent PVC-coated sheets which are summarized to form hexagonal honeycomb structures, lined with plastic on the inside and dimensionally stable glued.
  • these plastic PVC PVC pipes have strong combustion or hot spot areas.
  • the residence time of the exhaust gas flow in the electric field of the wet electrostatic precipitator is an important reference, since the polarization and ionization probability of the exhaust gas flow is influenced by water / liquid molecules of the spray liquid oriented in the E field, even in a collision cascade.
  • the outflow speed and the design of the exhaust gas purification line to a co-determining the efficiency of the cleaning system factor.
  • the DE 533 849 A1 describes a wet electrostatic precipitator with a sprinkling path, wherein the distance between not sprinkled to be sprinkled electrodes is chosen so that caused by the E-field flashovers are to be avoided. This is ensured by appropriate spacing of the so-called support / support rods of the electrodes.
  • From the DE 574 079 A1 takes a multi-stage wet electrostatic precipitator, consisting of a chamber, within this chamber cleaning stages are introduced, which are able to clean, for example, coke oven exhaust gases.
  • the wet electrostatic precipitators are designed according to the publications metallic.
  • the EP 0600011 A1 describes a wet electrostatic filter assembly consisting of a gas treatment line, a spray field, a funnel field, a liquid receiver and an extraction vessel.
  • the liquid spray mist field and its spatial and temporal distribution within the exhaust gas purification section is attributed an essential cleaning contribution.
  • the EP 0600011 A1 suggests this To produce a funnel-shaped spray field, wherein the industrial waste to be purified is subjected to a treatment with different liquids in successive and in series cleaning stages / sections.
  • the entire spray field consists of different liquids or liquid mixtures, so that a fractional purification of the exhaust gas flow - adapted to the exhaust gas composition - is achieved.
  • the physico-chemical reaction kinetics of different exhaust gas molecule compositions in the exhaust stream through the respective fluid is taken into account, the temporal probability of residence of the exhaust gases in the spray field - in conjunction with the different spray liquids - is crucial for the efficiency and separation efficiency of the emission control stage.
  • the E-field is designed so that a group of electrodes - even with different potentials - builds up an electric field distribution along the exhaust gas purification path, thereby avoiding flashovers due to spatial differences in potential.
  • a high sulfur oxide content located in the exhaust gas stream can significantly reduce the breakdown voltage of a wet electrostatic filter or a wet electrostatic filter device and thus ultimately the breakdown probability in the built-up E field depends on the concentrations of the exhaust gas composition. For example, if a high concentration of electrically highly polarizable components of exhaust gas - meaning exhaust components whose molecules have a high dipole or quadrupole moment - in the exhaust stream, the rollover probability with increasing electric field strength is higher and the efficiency of the emission control section is reduced in terms of achievable emission control quality ,
  • the DE 299 20 576 U1 describes a wet electrostatic precipitator for separating sulfur oxides and sulfur-containing dusts, wherein a plurality of elongated and parallel filter cells - consisting of plastic tubes - is used, which are bundled or arranged in a honeycomb structure.
  • the DE 299 24 343 U1 describes support collars for the bundle mounting of wet electrostatic filter tubes in selected and preferred storage sections that are attachable along the exhaust purification path.
  • honeycomb hollow plastic body preferably polyolefins, which can be welded together very well to form the honeycomb structure for a wet electrostatic filter arrangement.
  • Wet electrostatic filter assemblies are usually equipped with a series of vertical tubes through which the exhaust stream of an industrial plant to be cleaned flows. In the middle of the tube, electrodes are suspended or attached in such a way that particles in the exhaust gas flow are electrostatically charged.
  • the polarized and charged exhaust particulates are attracted to the inner wall of the tube, in the sense of an electrostatic cylinder capacitor, with the inner surfaces constantly flushed with water and the exhaust gas containing water subsequently drained into a collection tank called a settling tank, thereby reducing particles to a size be removed from the exhaust stream of about 1 micron.
  • the purified water is returned to the circulation, whereby a continuous interior wall wetting or mecanicwandberieselung the wet electrostatic precipitator takes place with the purified water.
  • the quality of an emission control system is also characterized by the purification of particles in the exhaust gas stream with a size of less than one micron particle size.
  • a high degree of separation or separation of pollutant particles contained in the exhaust stream advantageously and permanently determines the environmental impact of the respective emission control system and is to be seen in connection with the global exhaust gas reduction strategy.
  • the exhaust gas carried from the dryer is cooled in a piping system by injecting water to the saturation point and then passes into a filter device, wherein the exhaust gas to be cleaned is expanded over the entire cross section. In the subsequent gas scrubber process, dust and gaseous organic compounds are separated.
  • the pre-dried exhaust gas - so-called "dryer exhaust” - then flows into the wet electrostatic precipitator, which consists for example of different high voltage field arrangements and is equipped centrally with arranged in the wet electrostatic precipitator electrodes.
  • the particles and aerosols still contained in the exhaust gas flow in this process are also negatively charged or polarized by the E-field and move along the field lines towards the honeycomb or tubular inner surface of the wet electrostatic precipitator, the surface cleaning by a periodic or continuous Wasserbe réelleung or Wasserbesprayung and thus particle removal experiences.
  • the high-voltage system into, for example, two electric field areas with respective electric field zones, the water flushing of only one half of the inner surface of a wet electrostatic filter is possible.
  • the exhaust gas flow is guided through a flap device via the respective wet electrostatic precipitator half in operation. This allows targeted sections of the interior surfaces of wet electrostatic precipitators to be cleaned of adsorbed particles during operation of the emission control system.
  • the DE 10341980 A1 discloses a device for separating paint overspray from an overspray particle-containing air stream by means of at least one separation stage.
  • This device should make it possible to sequentially overspray particles of different types of overspray, in particular different colors, sorted and able to detect.
  • at least one separation stage has at least two particle collection areas, which can be arranged alternately in the flow path of the same subregion of the air stream containing the overspray particles.
  • the device comprises at least one separating element with at least one particle collecting area and at least one cleaning device for cleaning particles from the at least one separating element.
  • This cleaning device can be designed, for example, as a wet cleaning device.
  • the cleaning device comprises a cleaning container which is filled with a cleaning bath of water and / or of a solvent.
  • the sieve passes through the cleaning bath, so that by passing the sieve through the cleaning bath, the overspray particles adhering to the sieve are detached from the sieve by the liquid cleaning agent of the cleaning bath.
  • the cleaning action of the cleaning bath is mechanical by means of rotating brushes and cleaning nozzles arranged in the cleaning bath, which generate a stream of the liquid cleaning agent directed transversely to the main surfaces of the sieve through the sieve and are arranged on the opposite side of the sieve from each of the rotating brushes supported.
  • the disadvantage is that in the described method in operation additional maintenance and cleaning incurred, which are caused by large-scale particle agglomerations on the inner surface of the wet electrostatic precipitator of an emission control system and must be partially removed manually.
  • the object of the invention is to provide a tubular or honeycomb-shaped wet electrostatic filter, in which a particle agglomeration and deposition is reduced in the long-term operation of the exhaust gas purification system, the electric field stabilized and electrical flashovers are prevented.
  • an electrically conductive non-stick coating or anti-adhesion layer on the wet electrostatic filter inside.

  • This layer can also consist of a multi-layer / multi-layer layer sequence - in the sense of a sandwich layer - of different coatings and with an anti-adhesion coating applied thereto and with matched dielectric values or volume resistance values.
  • the matching of the dielectric values of the applied coating materials on the inner surface of the wet electrostatic precipitator advantageously results in electric field stabilization at high exhaust gas volume flow rates and at different polar exhaust particles, thereby improving the separation efficiency of the particles to be filtered out of the exhaust gas flow.
  • the electroconductive non-stick coating or non-stick layer may also be applied as a sandwich-like layer on the inner surface of the wet electrostatic filter. For this it is necessary to make an adjustment of the materials and fillers and the resulting dielectric constant. It was further recognized that the electric field behavior is improved by a gradient in the filler composition, starting from the inner and the exhaust gas flow directly facing electrically conductive anti-stick layer coating, toward the base body of the tubular or honeycomb wet electrostatic filter.

  • Due to the adjusted filler gradient in the respective electrically conductive anti-adhesion layer - even in a multilayer (sandwich) layer structure - is advantageously achieved that an adjustment of the dielectric ratios (ie dielectric: exhaust gas composition, liquid and wet electrostatic precipitator) with the coated, honeycomb or tubular inner surface of a Wet electrostatic filter is created.
  • the dielectric thus becomes adjustable and leads to a homogeneous electric field line stability of the wet electrostatic filters during operation.
