Definitions
- the invention relates to the structure of emission control systems for cleaning aerosols loaded gases or atmospheres and types of emission control systems having such a structure.
- the invention is to be embedded in the technology of electrostatic particle separation, in particular of a space-charge-type electrostatic particle separator.
- a space charge separator unipolar charged particles are deposited according to the field of their own space charge [1].
- wet scrubbers have provided a useful improvement in efficiency in which the particles / aerosols are loaded prior to entering the scrubber. Charged particles are separated by the wet scrubbing process and the electrostatic deposition under the influence of the space charge.
- An electrostatic precipitator also operates on the principle of mutual repulsion of the charged particles on a wall to reference potential, preferably ground potential. As the charged particles pass through the grounded portion of a precipitator, a portion of the charged particles are forced to the grounded wall by the electric field generated by the space charge. Deposited particles are entrained and discharged in the co-flowing water flowing down the walls of the grounded tube electrodes.
- a gas stream to be processed is ionized before it passes through the wet scrubber in order to provide the particles / aerosols in the gas stream with an electrical charge of predetermined polarity.
- the charged particles / aerosols become close to the scrubber liquid and / or packing elements as an effect of the attractive forces between the charged particles and the electrically neutral packing elements and the liquid carried. The particles are removed from the gas stream through the scrubber liquid.
- a particle of ionizing scrubber (see, for example, US Pat., Pub., 2006/0236858 A1 consists of a charge and collector section.)
- the collector consists of either a fixed or liquid bed packed section continuously irrigated from above charged particles are transported directly from the charging means to the collector means and the clean gas then passes through a liquid separator to remove liquid droplets.
- the described separator have a collection chamber between the charging device and the collector device, therefore, the space charge distribution at the collector input is homogeneous.
- the direction of the gas flow at the inlet and at the outlet of the collector is the same.
- electrostatic space charge separators without collecting chamber between the charging device and the collector device (see for example US 4,072,477 or DE 10 2006 055 543).
- the output of the charging device is attached to a chamber which has electrically conductive packing material, for. B. tower packing elements.
- the direction of the gas flow at the entrance and exit is either the same or the gas flow changes direction within the collector means.
- the space charge distribution in the input area of the collector is not homogeneous. It is maximum in the area where the gas stream enters the collector and is minimal in relation to the entrance area to the wall. There is a non-homogeneous space charge distribution. As particles are separated, the space charge field decreases and the aerosol collection worsens in the central and upstream entrance areas.
- the invention has for its object to make the deposition of electrically charged particles in the inlet region of a collector of an electrostatic emission control system more effective.
- an exhaust gas purification system for purifying aerosols loaded gases or atmospheres is known to consist of at least one assembly of an ionization and adjoining it in the flow direction collector device.
- the emission control system is fitted with its input to a raw gas duct or to raw gas ducts. It flows at its outlet clean gas flows into the environment or in a secondary exhaust duct.
- the ionization device of an assembly consists of at least one plane perpendicular to the channel axis with at least two identical, lying in a plane, the channel axis equally distributed ionization stages through which the gas flows radially with respect to the channel axis.
- the gas streams change their direction of flow into the associated collector device, which is centrally seated with respect to the channel axis. They are deflected into a common flow direction after the confluence with the collector, so that, in the collector region, the clear cross section in FIG Course of the gas flow with respect to the channel axis not oblique, not one-sided flow profile sets.
- the collector device consists of collector stages, which in each case connects to an ionization of the ionization, in which the radial gas flow from the associated ionization stage opens and pivots in the course of gas flow parallel to the channel axis to (claim 1) ,
- an emission control system specified as follows, namely the emission control system consists of at least two, channel axially juxtaposed assemblies of one ionization and central collector device, in which the central collector devices follow each other directly and initial component to the gas continuing channel.
- the first upstream central collector device upstream of the gas allows the gas streams flowing into it to flow and flow only to the following central collector device.
- an additive gas flow composed of flows emerges from the gas collector downstream of the last collector device.
- the assemblies with respect to the channel axis similar or twisted to each other.
- the emission control system now consists of at least two modules lined up in a row axial from one ionizing and collector device each.
- the number of ionization stages per module is the same and the gas flow in the ionization stages of successive modules is radially opposite.
- the channel leading the raw gas with its terminating channel piece closed at the end, either fans the raw gas stream via openings in its jacket wall to the attached ionization device of the first component flowed into partial gas streams of one ionization stage in order to radially outwardly reach the respectively attached collector stage stream.
- a channel piece leads to associated ionization stage of the following module, in which the partial gas flow flows radially inward. All partial gas flows through this assembly open into the associated central collector means, redirect there and continue to flow together axially for discharging or reprocessing.
- the gas stream composed of the partial gas streams flows into the axially adjoining, end-side sealed channel piece and fanning in through openings in the jacket wall back into the attached ionization stages of the following assembly. Now they flow radially outward there to the respective collector stage to flow from there to the respective or summarized discharge or reprocessing in a subsequent assembly.
- the exhaust gas purification system consists of a first gas channel section-like hollow cylindrical piece as ionization device whose wall intersects at least one plane perpendicular to the channel axis. In this sit the ionization stages through the hollow cylinder wall around the circumference uniformly distributed. They are surrounded by a second gas channel cross-section-like hollow cylinder piece like a shell over at least the length of the first hollow cylinder.
- either the raw gas channel opens into the first hollow cylindrical piece, which is closed on the opposite end, in such a way that the raw gas has to flow radially outwards through the ionization stages, and the second, surrounding hollow cylindrical piece through an annular disc raw gas side with the first hollow cylindrical piece connected in a gastight manner.
- This forms the collector for the gas flowing in from the ionization stages, from where the gas stream recombined therein exits as clean gas stream on the off-gas side, open end.
- the raw gas channel flanges on the second hollow cylinder on the front side.
- the second hollow cylinder is connected to the first hollow cylinder on the side facing away from the raw gas stream via a gas-tight annular disk, while the first hollow cylindrical piece is closed at the end facing the Rohgas- ström.
- the raw gas channel flanges on the second hollow cylinder shell-side and forms with the first hollow cylinder a front side gas-tight closed, annular cavity.
- the partial flows redirect there and continue to flow as a total flow from the first hollow cylinder through the collector device.
- the clear cross-section of the first hollow cylinder is closed gas-tight at the end facing away from the further flow.
- the gas channel cross-section seen from the outside, is convexly round or convexly polygonal.
- the situation is thus improved by changing the way in which a gas stream flows into the inlet area of a collector device.
- the improvement relates to electrostatic precipitators without collecting chamber between the charging / ionizing device and the collector device, in which the gas in the input of the collector device only through an opening in a side wall of the collector device, in which the gas flow within the collector changes direction.

- Figure 7b circular cylindrical collector device in plan view with a wall portion as ionization
- FIG. 9 shows a side view of a separator consisting of two separator planes with plane-wise radially opposite gas flow in the ionization devices
- the space charge separators known from the prior art (US 4,072,477 Fig. 1, and DE 10 2006 055 543, Fign.13 and 14) are presented as a comparison here in Fig. 1.
- the output of the charging / ionizing device is coupled to a grounded collector device constructed of electrically conductive packing material, for example tower packing elements.
- the gas flow changes its flow direction in the input region of the collector device.
- the gas flow enters the inlet region of the collimator device only from the one left-hand opening in the image; it is coarse and, by two parallel vertical lines, into the regions following one another in the entrance region over the clear width: entrance, central and opposite, divided.
- the space charge density decreases there in the axial extension of the opening axis to the opposite wall of the collector device from.
- FIG. 2b shows the course of the decrease of the space charge or the space charge density profile qualitatively with one-sided inflow from the ionization stage: the space charge density is initially maximum in the entrance area, decreases rapidly towards the center and becomes minimal at the opposite wall.
- the course of the space charge density decreases from the inflow opening to the opposite wall, ie over the clear diameter there, monotonously or obliquely.
- the entrance area of the collector means is used ineffectively for particle deposition / collection.
- the loaded with charged particles / aerosols gas penetrates via opposing openings in the collector. Therefore, more charged particles penetrate into the central entrance area, where they increase the space charge density. This increases the deposition efficiency and makes more intensive use of the entry area for particle collection.
- the turbulence increases the space charge distribution and thus the collector efficiency.
- the separator in which the gas stream with charged particles / aerosols from at least two mutually opposite openings in the side walls in the inlet region of the collector 3 enters, is shown schematically in Figures 3a) in the side view and in Figure 3b) in plan view.
- the separator includes the charging / ionizing device consisting of these, for example, two channels / ionization stages 1 and 2. The direction of gas flow is indicated by arrow.
- the charging / ionizing device can consist of two but also more than two channels / ionization stages. An even number of ionization stages is preferable because then, with equal distribution about the axis of the separator, there are always two openings of ionization stages in the entry region axially facing each other and the space charge densities in the two successive gas flows over the clear cross section of the collector entry region as desired , hump-shaped superimpose, provided that the inflows are equally strong. With 3 or more odd-numbered, high-flow inflows into the collector inlet area, an asymmetrical space charge density distribution over the clear cross-section with increasing number of inflows is always weaker, ie becomes more symmetrical. Unequal strong Inflows into the inlet region result in an asymmetry of the space charge profile over the clear cross section with respect to the separator axis, which is dependent on the inflow intensities.
- FIG. 4 shows the construction of a separator in which the four ionization stages 1, 2, 4, 5 of the ionization device lie in a plane perpendicular to the axis of the precipitator, uniformly distributed around this axis and there are always two such ionization stages 1, 2 and 4, respectively. 5 are facing with their inlet opening in the central collector means 3, d. H. the two gas flows from the ionization stages 1 and 2 as well as 4 and 5 are directed towards each other or the axes of these inlet openings coincide in pairs. The respective gas flow through the ionization stages 1, 2, 4, 5 flows radially to the axis of the separator, as indicated by the arrows.
- the ionization device consists of at least four ionization stages, these can be distributed over at least two levels arranged one after the other in the same way. Seen in Abscheideraxialer direction, congruent or rotated by an angle ⁇ against each other, if the planes are identical. Otherwise, the uniform distribution of the ionization stages around the separator axis applies, so that the required space charge density distribution in the entry region of the central collector device is more easily achieved.
- Figures 5a and 5b show a congruent two-stage construction of the separator with each directed radially inward to the separator axis flow through the ionization stages 1, 2 and 4, 5 (claim 3).
- the two central collector devices are built together, they follow one another continuously and therefore form the entire central collector means 3.
- FIG. 5a shows the side view of the separator structure with the respective indicated High voltage connection HV per ionization stage.
- FIG. 5b shows the
- FIG. 6 shows, for example, the rotation of the two identical planes of the ionization device, which are rotated relative to one another about the separator axis by the angle ⁇ , which is pointed here.
- a construction of the space charge separator such that the ionization device with its inlet openings in the collector device form part of the same is shown in a convexly round, here specifically circular cylindrical design in Figures 7a and 7b.
- the gas stream enters the charging / ionizing device 7 through the shell wall side flange 9 for the raw gas channel in the comprehensive annular channel 6 and radially inwardly through the ionizing 8 therethrough.
- the ionizing nozzles 8 are located in several parallel successive planes in the circular hollow cylinder wall, or the ionizing device 7 is formed here.
- the plane-wise radial inflow therefrom into the central collector device causes per plane the distribution of the space charge density over the clear cross-section of the inlet region and is rotationally symmetrical with at least planar flow equality from the ionizing nozzles 8 to the separator axis.
- the hollow cylindrical wall section with the ionizing nozzles 8 in the inlet region of the collector device with a circular light cross section can be used as a circularly curved, grounded nozzle plate, as described in DE 10 2006 055 543, (DE 10 2005 4045 010 and DE 10 2005 023 521 and DE 102 44 051), to which the central collector device in the direction of flow is directly attached to the front side, here above in the image of FIG. 7a.
- Figures 8a and 8b show a convex polygonal, specially quadrangular construction of the separator (claim 6) in the manner of the convex round, specially circular separator according to Figures 7a and 7b.
- Its ionization device consists of four flat nozzle plates approximately according to DE 10 2006 055 0543, which form a rectangular clear cross-section. Raw gas inflow and clean gas outflow are indicated as in FIG. 7a. Here, too, several levels of ionization stages are strung together in a separator-like manner.
- the separator is closed at one end face by a plate as in the structure according to FIGS. 7a and 8a, which is indicated by the thick line in the image below.
- Figure 9 illustrates how the embodiment according to claim 4 can be realized by way of example.
- the raw gas introduced in the picture (arrow) enters vertically centrally into the separator, the channel leading to the raw gas, he is not shown, flanges with its tail on the end face closed in channel piece 11, from which the raw gas flow to the left and on the right in the picture, that is under direction change, in the respective charge / ionization stage 1 and 2 divides, preferably evenly.
- Both partial gas streams flow through their ionization stage 1, 2 with respect to the Abscheiderachse radially outward, in which in each case the ionization of the particles / aerosols via high voltage HV.
- the gas streams enter the outside, directly mounted collector 10, the outer collector 10, and are forcibly deflected upward in the image.
- a front side down closed pipe section which is closed at its lowest point and there has a discharge device, see indicated small flange.
- a frontally flanged in Verlan- The pipe wall is closed at the corresponding ionization stage. The initially vertically upwardly flowing partial gas flow thus enters with deflection into the following ionization stage 4 or 5 and flows therein radially inwardly towards the separator axis.
- the gas flow with particles / aerosols passes through the charging / ionizing device, which is not presented in detail here in writing or in the drawing. For example, it can be taken from DE 10 2006 055 546.
- the particles in the gas stream are electrically charged in the field of a corona discharge.
- the aerosol-laden gas stream passes through the ionization stages 1 and 2 or 1, 2, 4, 5, depending on the design of the separator in the inlet region of the collector means 3. Since the entry into the collector means, over the clear As seen in cross-section, there is no longer a one-sided space charge density distribution decreasing towards the opposite wall, a much more effective collection of the electrically charged ones occurs in the collector Particles. This advantageous over the clear cross-section, preferably symmetrical to the separator axis, so no longer unilaterally decreasing distribution of space charge leads to the much more effective deposition, which comes about only by the counterflow and rectified deflection of two partial gas streams.
- the advantage of the separator according to the invention is the process-supporting use of the inlet region of the collector device. As a result, the size of the collector device can be significantly reduced and the collector housing can be made smaller. Thus, a compact design of the separator is given, in particular, this is apparent from the exemplary embodiment according to Figures 7a to 8b. This includes the cost reduction for the construction of the space charge separator and thus investment costs.
