Definitions
- the invention relates to a plastic pipe for wet electrostatic precipitator and a kit for an emission control system.
- plastic pipes for use in wet electrostatic filter systems for the purification of exhaust-gas-containing exhaust air streams in power plants, chemical plants, etc. are known from the prior art.
- 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-type electrostatic precipitators are used if solid particles in the exhaust gas stream are to be mixed with a liquid or if 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.
- Continuous spraying with finely divided water droplets thus produces a uniformly distributed, droplet-like film over the entire sprayed exhaust gas volume.
- the solid particles contained in the exhaust stream are electrostatically charged / polarized by electrodes in the E-field, and move along the electrostatic field lines to the inner surface of the wet electrostatic filter, entraining particles from the downward spray water film.
- 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 electro-filter unit.
- the exhaust gas separation performance of a wet electrostatic precipitator is essentially determined by the physico-chemical 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 E-field.
- tubular or honeycomb wet electrostatic filters currently in use also permit the separation / separation of quasi-tacky, liquid or solid particles of different sizes from an exhaust gas flow.
- the residence time of the exhaust gas flow in the electric field of the wet-electrowater filter 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 aligned in the E-FeId, also in a collision cascade , Thus, the outflow speed and the design of the exhaust gas purification line to a co-determining the efficiency of the cleaning system factor.
- DE 533 849 A1 describes a wet electrostatic filter system with a sprinkling section, wherein the distance between non-irrigated electrodes to be sprinkled is chosen such that arcing caused by the E-field is to be avoided. This is ensured by appropriate spacing of the so-called support / support rods of the electrodes.
- a multi-stage wet electrostatic filter consisting of a chamber, within which 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.
- EP 92 918 939 A1 describes a wet electrostatic filter arrangement which consists of a gas treatment line, a spray field, a funnel field, a collection container for the liquid and an extraction container.
- the liquid spray field and its spatial and temporal distribution within the exhaust gas purification section is attributed an essential cleaning contribution.
- EP 92 918 939 A1 proposes 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-FeId is designed so that a group of electrodes - even with different potentials - builds up an electric field distribution along the emission control section, which arcs of potential differences are avoided as possible.
- 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. If, for example, 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 gas flow, the rollover probability increases with increasing electric field strength and the efficiency of the exhaust gas purification path is reduced in terms of achievable emission control quality.
- 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.
- 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 réellewandberieselung 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.
- the low energy consumption, the low operating costs with high exhaust gas throughput per hour as well as a high plant availability are further decisive economic parameters for the operation of such a plant.
- 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 gas” - then flows into the wet electrostatic precipitator, which consists for example of different high-voltage field arrangements and is equipped centrally with electrodes arranged in the wet electrostatic filter.
- the particles and aerosols still contained in the exhaust gas stream in this process are likewise denoted by the E FeId negatively charged or polarized and move along the field lines towards the honeycomb or tubular inner surface of the wet electrostatic filter, which undergoes a surface cleaning or particle removal by a periodic or continuous Wasserbe Togetherung or Wassbesprayung
- the exhaust gas flow is through a flap device on the respective operating wet electrostatic precipitator half out. 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 object of the invention is to provide a tubular or honeycomb-shaped wet electrostatic precipitator, in which a particle agglomeration and deposition in the long-term operation of the exhaust gas purification system is reduced, the E-FeId stabilized and electrical flashovers are prevented.
- an electrically conductive non-stick coating or anti-adhesion layer on the wet electrostatic filter inside.
- the tubular or honeycomb wet electrostatic filter is coated on its 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 filter 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.
- the electrical field behavior is improved by a gradient in the filler composition, starting from the electrically conductive non-stick layer / coating directly facing the inside and the exhaust gas stream, toward the base body of the tubular or honeycomb wet electrostatic filter.
- Suitable plastic material for the electrically conductive non-stick coating or layer are polyethylene (PE) and / or polypropylene (PP) and / or polystyrene (PS) having a filler content of from 5 to 35% by weight of carbon black according to the invention, and also PVC having a filler content of 5 to 35% by weight of carbon black and / or polyoxymethylene (POM) having a filler content of 5 to 35% by weight of carbon black.
- PE polyethylene
- PP polypropylene
- PS polystyrene
- PVC polystyrene
- POM polyoxymethylene
- polyamide compounds such as PA 66 with a filler content of 5 to 20% by weight with metal fibers and a metal fiber length of 0.01 mm to 5 mm are also suitable.
- PA polyamide compounds
- PC polycarbonates
- metal fibers consisting of steel and / or copper and / or lead and / or brass as well as non-ferrous metal compounds with said metal fiber lengths can be used as fiber-containing fillers.
- fillers consisting of carbon-containing fibers with a filler content of 10 to 40% by weight are also usable according to the invention.
- PET polyethylene terephthalate
- PBT polybutylene terephthalate
- PPS polyphenylene sulfide
- PEI polyetherimide
- an increased electrical breakdown / flashover resistance of the wet electrostatic precipitator in an exhaust gas purification system in the operating state is thus achieved and the plant availability of the exhaust gas purification system for the operator is increased.
- the filler content of the electrically conductive polymeric inner layers of the wet electrostatic precipitators is set according to the invention to specific volume resistivity values in the range of 7 to 10 -2 ⁇ cm.
- the so-coated and filler-containing tubular or honeycomb-shaped wet electrostatic precipitators showed in experiments that exhaust gas particles in the size of 0.3 ⁇ m to 1 ⁇ m can be easily separated or cleaned from the exhaust gas flow.
- dielectric ratios ie dielectric: exhaust gas composition, liquid and wet electrostatic filter
- the invention further teaches to use a tube-shaped or honeycomb-shaped wet electrostatic filter bundle - hereinafter referred to as a kit - consisting of a plurality of tubular or honeycomb wet-type filter media according to claim 13.
- Conceivable in this context of the invention are tubular or honeycomb-shaped wet electrostatic filter assemblies which are composed of, for example, alternating, electrically conductive, non-stick coating materials and filler contents according to claims 4 to 10. This can be adapted to the exhaust gas to be cleaned in the exhaust stream, achieve an optimized cleaning arrangement by means of the wet electrostatic precipitator.
