Abstract
An electrostatic precipitator for removing particles from a gas stream includes electrically chargeable electrode elements suspended from the housing of the precipitator and grounded collector plates fixedly supported by the housing in positions between adjacent pairs of electrode elements to leave a clearance therebetween. An electrode stabilizer extends through an opening in one of the collector plates without touching the collector plates to connect a pair adjacent electrode elements. The stabilizer and pair of electrode elements are configured to form a rigid structure substantially eliminating sway between the electrodes and collector plates.
Description
DI8C~P~ ELECTRODE 8TABILIZER
Background Of The Invention The invention relates to electrostatic precipitators and in particular to a frame for stabilizing discharge electrode elements in an electrostatic precipitator.
Electrostatic precipitators are used to remove particulate from an exhaust gas stream. Such precipitators generally include a plurality of parallel discharge electrode elements alternating with a plurality of grounded collecting electrode plates. The discharge electrode elements comprise formed sheet metal configurations vertically hung in the direction of gas flow. The grounded collector plates comprise formed sheet metal plates spaced from and aligned parallel to the electrode discharge elements. The grounded collecting electrode plates are generally mounted and stabilized directly from the precipitator casing or housing.
When a particulate laden gas flows through the spaces between the discharge electrode elements and the grounded collector plates, particulate in the gas take on a charge from the electric corona discharge emanating from the discharge elements. The charged particles are subsequently attracted to the grounded collecting electrode plates. By this mechanism, particulate are removed from the exhaust gas flowing through the precipitator. In conventional precipitators, the collector plates are tapped with a rapping device so as to force the collected particulate down the collecting plate and into a collection chamber.
207~i21~
- One currently utilized electrostatic precipitator design is shown in Figure 1. The precipitator includes a casing or housing 10 that encloses a plurality of electrically charged sheet metal elements 12 interspaced with alternating grounded collector plates 14. Particulate laden air 13 enters the front of the precipitator casing 10 and passes through the spaces between discharge electrode elements 12 and collector plates 14 so as to remove particulate. Clean air 15 then exits through an opening in back of the precipitator housing.
Discharge electrode elements 12 are suspended from a support frame 16, which includes first frame members 16a extending parallel to the longitudinal dimension of the housing and second frame members 16b extending perpendicular to the first frame members 16a and connected therebetween. The support frame 16 is suspended from electrically insulated supports 18 mounted on the top of housing 10 and connected to frame members 16b. The top of each electrode element 12 is connected to the spaced frame members 16a. A steadying frame 20 engages the bottom of each discharge electrode element 12 so as to reduce swaying of the electrode plates. The connection of the plates 14 to the casing 10 is not illustrated for purposes of clarity. However, the grounded collector plates 14 are mounted directly on the casing 10 via hanger bolts and anvil beams to form a fixed connection with the housing end girders.
When the discharge electrode elements 12 of the electrostatic precipitator shown in Figure 1 are charged, they are attracted to the grounded collector plates 14. This 2~7621~
attraction often results in regular swaying of the discharge electrode elements. Such swaying is a problem because it changes the distance between the discharge electrode elements and collector plates so as to reduce the efficiency of the electrostatic precipitator. In some instances, regular harmonic swaying occurs in which circumstances the amount of sway may be so great as to bring discharge electrode elements 12 into contact with some of the collector plates 14.
Such contact damages the precipitator unit. The steadying frame 20 is used to reduce sway of the electrode plates 12.
However, steadying frame 20 does not eliminate sway altogether.
To overcome the sway problem, conventional electrostatic precipitators have utilized a spacer steadying bar 22 installed between a discharge electrode plate and a collector plate. Figure 2 is a cross sectional view of the precipitator shown in Figure 1 looking in the direction of gas flow. As shown in Figure 2, a number of spacer steadying bars 22 are fixed between the steadying frame 20 and a collector plate 14. Such spacer steadying bars are made of an electric insulating material in order to prevent flow of electric current from the discharge electrode elements to the collector plate. The spacer steadying bar 22 prevents the discharge electrode elements from swaying because all of the electrode elements sway only in unison due to the interconnection of steadying frame 20.
When spacer steadying bars are used to reduce swaying of discharge electrodes, particulate stick to the surface of the spacer steadying bars. This particulate build up causes 207621 ~
- electric current channels to form between the discharge electrode elements and the collecting plate through the particulate coating on the surface of the spacer steadying bars. The surface currents result in spacer steadying bar degradation and eventual breakdown of the spacer steadying bar.
When such breakdown occurs, time consuming electrostatic precipitator repairs are required forcing the shut down of the equipment whose exhaust gas is being cleaned by the precipitator.
Summary Of The Invention Accordingly, the invention is directed to providing an electrostatic precipitator in which discharge electrode sway is prevented by a stabilizer system that is less prone to regular mechanical breakdowns. The invention also provides a frame that stabilizes discharge electrode elements of an electrostatic precipitator without attachments between the electrode elements and the grounded collector plates of the precipitator or the precipitator's grounded housing structure.
Furthermore, the invention provides a discharge electrode stabilizer system that can be fitted on both existing and new electrostatic precipitators without great expense.
More specifically, the invention provides an electronic air cleaner for removing particulate materials from a gas stream flowing through its housing that includes a plurality of aligned electrically chargeable electrode elements suspended from the housing. At least one grounded collector plate is fixedly supported by the housing and aligned between 207fi21 9 - two of the plurality of electrode elements in a position spaced from the two electrode elements to form a clearance therebetween. The collector plate has an opening and an electrode stabilizer extends between the two of the plurality of the electrode elements. The stabilizer passes through the opening in the collector plate without touching the collector plate. The stabilizer and the two electrode elements are configured to form a rigid stabilizing system or structure substantially eliminating sway between the electrode elements and the collector plates.

Detailed Description Reference will now be made in detail to the embodiment of the invention illustrated in the accompanying 2076~l9 - drawings. Throughout the drawings, like reference characters are used to designate like elements.
A cross-sectional view of an electronic air cleaner constructed according to the principles of the invention is illustrated in Fig. 3. Fig. 3 shows a cross-sectional view of an electrostatic precipitator looking in the direction of air flow. According to the illustrated embodiment, the electrostatic precipitator of the invention includes a casing 10' in which a plurality of electrode discharge elements 12' and a plurality of grounded collector plates 14' are housed. Discharge electrode elements 12' are suspended from a support frame 16', which in turn is suspended from electrically insulated supports 18' mounted on the top of housing 10' in the manner previously mentioned in connection with the discussion of Figures 1-2. The grounded collector plates 14' are fixedly mounted on housing 10' by hanger bolts and anvil beams supported on the housing end girders, also in the manner previously discussed in connection with Figures 1-2.
The electrode stabilizer system of the invention preferably comprises a rigid stabilizer frame 24 affixed only to two of the plurality of electrode elements. Alternatively, frame 24 could be connected to more than two of the discharge electrodes. Rigid stabilizer frame 24 and the two adjacent discharge electrodes 12' to which the stabilizer frame is affixed form a rigid structure that substantially eliminates sway between the electrode elements and the interspaced collector plate. Preferably, stabilizer frame 24 is made of the same electrically conducting material as the electrode 207~
- discharge elements 12'. As embodied herein, both the electrode elements 12' and the rigid stabilizer 24 are made of metal.
Stabilizer 24 may be affixed to electrode elements 12' by any known method, including welding the stabilizer frame to the electrode elements.
The electrode stabilizer frame passes through an opening in one of the collector plates 14' such that the stabilizer frame connects two adjoining electrode elements without touching collector plate 14' therebetween.
Alternatively, the term "opening" as used herein includes the design of the collector plate 14' shown in Fig. 3, which is shorter than the other collector plates to permit the frame 24 to pass underneath the plate 14' and above steadying frame 20'.
Figure 4 shows stabilizer frame 24 passing through an indentation or hole 13 in collector plate 14'.
Stabilizer frame 24 preferably comprises a plurality of cross members each affixed to two discharge electrode plates in a configuration that forms a non-deformable shape in conjunction with the two electrode plates and permits air to flow therethrough. One of the stabilizer frames 24 of the electrostatic precipitator shown in Fig. 3 is shown in greater detail in Fig. 4. The stabilizer frame is preferably comprised of a bent metal rod or strip affixed to adjoining electrode discharge elements 12'. As discussed above, the frame is attached to the electrode plates by welding or other known attachment methods and may be connected directly to electrodes 12', which may include an intermediate conducting plate 11 disposed between the electrodes and the frame.
2Q7~i21 9 ~- Frame 24 is configured in a manner to form with the electrodes 12' one or more generally triangular shapes having hollow spaces 25' through which air can flow. The triangular shape is beneficial because it forms a rigid and non-deformable truss-type member.
As can be seen in Fig. 3, collector plates 14' generally extend vertically from a point just below discharge electrode support frame 16' to a point just above discharge electrode steadying frame 20'. Collector plates 14' are aligned substantially parallel to electrode elements 12. The particulate-laden exhaust gas passes through the clearance left between discharge electrode elements 12' and collector plates 14', which is at least as large as the required electrical clearance.
As shown in Fig. 3, for example, just a few stabilizer frames can stabilize a large number of discharge electrode elements in an electrostatic precipitator. This stabilization is achieved because each of the electrode elements is connected at its top to support frame 16' and at its bottom to steadying frame 20'. Accordingly, when stabilizer frame 24 substantially eliminates sway between the two discharge electrodes 12' to which the frame is affixed and the interspaced collector electrode, sway of the other discharge electrodes 12' is also substantially eliminated through steadying frame 20'.
