Definitions
- the invention relates to an electrostatic precipitator according to the preamble of claim 1.
- EP 0 252 371 A1 describes an electrostatic precipitator in the form of an electrostatic dust separator, in which a particle-laden or dust-laden gas stream is guided between parallel deposition plates in a substantially cylindrical housing section. Between the parallel-aligned precipitation plates are longitudinally extending lanes in which tensioned discharge electrodes are arranged in frames.
- this is associated with various advantages.
- deflection of the plate bearings is avoided, as occurs, for example, in the prior art in firmly screwed plates by the knocking.
- the problem of mechanical distortion of permanently screwed or continuous plates is avoided, as occurs by thermal expansion. This leads to improved lifetime and more constant distance, for example, to voltage-carrying electrodes.
- the invention makes it possible to make the mechanism of the knock easier than, for example, in the case of firmly screwed plates.
- Preferred main application of an electrostatic precipitator according to the invention is the dedusting of converter gas.
- the gas purification system is alternately flowed through by dust-laden, combustible converter gas and only slightly dusty ambient air.
- the resulting flammable converter gas is collected in a gas container after the dust has been separated.
- a switching station installed after the filter allows the deflection of the non-combustible exhaust air via a chimney into the atmosphere. If converter gas and the oxygen-containing exhaust air of the blowing breaks mix, explosive gas mixtures can form, which can ignite in the oil filter and lead to deflagration. Such deflagrations can lead to dust surges, which affect the separation efficiency of the electrostatic precipitator.
- An inventive electrostatic filter is therefore particularly suitable for this field of application with the sum of its features, especially since the round housing shape enables a particularly favorable throughflow and at the same time good mechanical strength of the entire electrostatic precipitator.
- each of the Teiiplatten a pair of plates is flexible, in particular oscillatory arranged.
- a particularly effective tapping on the partial plates can be realized, wherein in particular the striking of the respective free end region of the partial plate, ie the lower end of a hanging partial plate and the upper end of a stationary partial plate occurs.
- a boundary between a respective upper and lower part plate substantially at half the height of the housing.
- this also includes the edge-side plates in a transverse direction, which are the shortest plates due to the round housing cross-section.
- the precipitation plates consisting of upper and lower partial plates form a total of one plate wall, which are struck by means of a knocking rod driven only on one side.
- the precipitation plates which consist of upper and lower partial plates, are guided by a tapping rod, so that the tapping rod effects both the striking and at least partially the reliable alignment or holding of the plates.
- reinforcing rings are arranged in the longitudinal direction one behind the other, wherein between two reinforcing rings, a field of precipitation plates is arranged.
- a field may, for example, consist of a plurality of mutually parallel plate walls which are each aligned parallel to a vertical direction and a longitudinal direction of the housing and each consist of a plurality of successively arranged in the longitudinal direction precipitation plates or pairs of partial plates.
- the housing can be formed much more resistant to pressure and static more stable, with supporting elements for the precipitation plates and / or electrode frame can be added to the reinforcing rings.
- at least one of the reinforcing rings is designed to be rotationally asymmetrical. This is to be understood in particular as meaning that the reinforcing ring has at least two significantly long sections of considerably different cross-sectional shape over its circumference.
- a support frame for receiving the lower, vertically mounted partial plates is received in a lower portion of the reinforcing ring.
- a lower portion of the reinforcing ring has a relation to an upper portion of weakened cross-sectional profile. In this way, for example, sufficient space can be created to support a support frame for the upright mounted sub-panels at the lower portion, without significantly reducing a free passage cross-section of the housing.
- the reinforcing ring has a tie rod, wherein the tie rod is arranged in a preferred embodiment in a region of a horizontal diameter.
- the tie rod is designed in the interest of a lightweight construction as a grid frame.
- the tie rod can generally be advantageously designed as a walk-walkway, so that it allows easy maintenance access to the precipitation plates.
- Fig. 1 shows a three-dimensional view of a field of precipitation plates of an electrostatic precipitator according to the invention.
- FIG. 2 shows a three-dimensional view of four reinforcing rings of the electric filter.
- An electrostatic precipitator comprises a housing (not shown) which has a substantially constant and substantially circular cross section in a cylindrical section, a longitudinal direction L of the electrostatic filter running in the direction of the cylinder axis, into which a flow through the electrostatic precipitator with a particle or dust-laden gas occurs.
- Such a field 2 is shown in FIG. It comprises a plurality of plate walls 4, each extending parallel to one another and extending in the longitudinal direction L and the vertical direction H, each consisting of a plurality of precipitation plates 3 arranged one after the other in the longitudinal direction L. Between the plate walls 4 lanes for gas passage extend, in which (not shown) electrode frame are arranged.
- the precipitation plates 3 each comprise an upper sub-plate 3a and a lower sub-plate 3b.
- the upper part plates 3 a are each suspended, namely on an upper support strip 5 of a respective plate wall 4.
- the support strips 5 protrude slightly beyond the field 2 and are mounted in corresponding receptacles 6 at upper portions 1 a of the support rings 1.
- the lower part plates 3b are received in a lower support frame 7 and stored vertically.
- the lower support frame 7 comprises end-face arcuate elbows 7a and rib members 7b extending therebetween and along the longitudinal direction L, to which the lower constituent plates 3b are received.
- the lower and upper sub-plates 3a, 3b can be considered as a total of centrally divided precipitation plate 3, wherein the two sub-plates are each mounted oscillating and flexible.
- the division level is approximately halfway up the precipitation plates or the electrostatic precipitator. Due to the design, the edge plates in the width direction B located side plates 3a, 3b or precipitation plates 3 are formed shorter than the centrally arranged in the width direction, which extend beyond the maximum free inner height of the electrostatic precipitator.
- an arrangement of a plurality of tapping poles 8 is provided, which are struck in the longitudinal direction L per field 2 by only a single stop mechanism (not shown). The tapping poles 8 of a field 2 are connected to each other by crossbars 9.
- Each individual sub-plate 3a, 3b is in each case located between two abutment blocks 8a of a knocking rod 8, so that the movably mounted sub-plates deflect in one direction after being hit by the first block and then strike against the second block. This achieves effective tapping of the collected dust from the precipitation plates.
- the knocking rods 8 constitute a guide for the movably mounted partitions 3a, 3b.
- the attachment of the knocking rod is made by depending on the requirements a) by a respective bolt at the lower end of two of the suspended mounted part plates (not shown), or b) by a respective pendulum joint with support structure on each end face (not shown).
- Both types of suspension are known in a similar manner from electrostatic precipitators of rectangular design, in which case there is no division of the precipitation plates and the continuous, exclusively hanging mounted plates are struck at its lower end.
- the elbows 7a of the lower support frame 7 are accommodated on the lower portions 1b of the reinforcing rings 1, for which purpose the lower portions have a cross-sectional profile weakened with respect to the upper portions 1a.
- the upper portions 1a have a rectangular profile cross-section and the lower portions 1b have a T-shaped cross section. Due to the different cross-sectional profiles of the sections 1 a, 1 b of the support ring 1 of this rotational asym metric is formed.
- the lower portion extends over slightly less than half the circumference of the support ring. From the upper portion 1a are also lateral, vertical supports 1c tangentially continued, by means of which an additional support of the entire E lektrofilter can take place.
- a tie rod 10 is provided, which extends along a horizontal diameter of the reinforcing rings 1.
- the tie rods are designed as lattice frames and designed as walkways, through which the electric goods can be better accessed for maintenance purposes.
