[0002] Electrostatic precipitator equipment is usually composed of 1-5 electric fields.

The expansion that cannot be released freely will cause the dust collecting electrode system to twist, deform, and fail.

DETAILED DESCRIPTION

[0046] The present invention is further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0047] In the present specification, it should be understood that terms such as “having”, “including” and “comprising” used herein do not exclude the existence or addition of one or more other elements or combinations thereof.

[0048] like Figure 1 As shown, the present invention provides a dust collecting electrode system, comprising: a dust collecting electrode assembly 1, which is located inside the dust collector; a suspension assembly 2, which is connected to the electrostatic precipitator, and the suspension assembly 2 is also connected to the dust collecting electrode assembly 1; and a vibration cleaning assembly 3, which is arranged on the dust collecting electrode assembly 1.

[0049] The dust collecting electrode system provided by the present invention is a suspended structure with a certain degree of freedom and less restraint. It can adapt to high temperature environments exceeding 450°C and ensure that the dust collecting electrode system does not twist or swing in high temperature environments, causing deformation of the internal structure and changing the discharge distance between it and the discharge electrode, resulting in failure. The expansion force can be released.

[0050] Based on the above situation, another embodiment, such as Figure 2 As shown, the dust collecting electrode assembly 1 includes a plurality of dust collecting electrode plates 4, and the dust collecting electrode plates 4 are connected to the suspension assembly 2. The plurality of dust collecting electrode plates are arranged in a row to form a plurality of dust collecting electrode plate rows 5, and the same pole spacing between a plurality of adjacent dust collecting electrode plates 4 is 350-550 mm.

[0051] The existing arc-shaped dust collecting electrode system has a small difference in the length of adjacent electrode rows, and the operating temperature is not high, so the expansion of the dust collecting electrode is relatively small and the reserved expansion gap is small. Under high temperature conditions, the expansion of the dust collecting electrode increases, and the linear expansion coefficient of the high temperature resistant material also increases, so it is necessary to adjust the length of the electrode and control the expansion of the same electrode spacing.

[0052] The dust collecting electrode plate rows of the dust collecting electrode system are vertically suspended in an orderly manner inside the electric field by the dust collecting electrode suspension system. The spacing between the dust collecting electrode plate rows is called the same-pole spacing. The same-pole spacing is generally between 350-550mm. In some individual cases, there are also same-pole spacings less than 350mm and greater than 550mm.

[0053] Specifically, Figure 2 and Figure 3 As shown, it also includes a plate fixture 6, one end of which is movably connected to the dust collecting plate row 5, and the other end of the plate fixture 6 is fixedly connected to the adjacent dust collecting plate row 5.

[0054] in, Figure 5 yes Figure 4 A partial enlarged view of the connection between the middle plate fixture and the dust collecting plate row.

[0055] Provide an embodiment, such as Figure 5 As shown, it also includes a steel plate 7 with an opening 8 formed thereon. The steel plate 7 is arranged on the side of the dust collecting electrode plate row 5. One end of the electrode plate fixture 6 is arranged in a movable manner so as to extend into the opening 8 to realize a movable connection between the electrode plate fixture and the dust collecting electrode plate row. The other end of the electrode plate fixture 6 is fixedly connected to the adjacent dust collecting electrode plate row 5.

[0056] Each row of dust collecting plate rows is connected by a plate fastener 6 that penetrates the dust collecting plate rows to prevent the dust collecting plate rows from twisting and deforming to affect the same pole spacing. The same pole spacing is ensured by a supporting steel plate at the fixed rod position between each adjacent row of dust collecting plate rows.

[0057] After the steel plate is opened, one end of the plate fastener is passed through the steel plate, and then welded to one row of plates, and the steel plate is welded to another row of plates. The end of the plate fastener that extends into the opening can move between the steel plates. This structure can ensure that the dust collecting plate row can release the expansion caused by the expansion when it expands to the left and right sides due to heat.

[0058] Of course, there are other active connection schemes that can be adjusted differently according to the environment in which the dust collecting electrode system is used.

[0059] The dust collecting electrode system provided by the present invention can avoid the problem that the dust collecting electrode system is twisted, deformed and fails due to thermal expansion under high temperature conditions.

[0060] Based on the above embodiment, another embodiment is as follows: Figure 6 The suspension assembly 2 includes a suspension beam 9 and a suspension plate 10. One end of the suspension beam 9 is slidably connected to the electrostatic precipitator, and the other end of the suspension beam 9 is fixedly connected to the electrostatic precipitator. One end of the suspension plate 10 is arranged between the suspension beams 9, and the other end of the suspension plate 10 is connected to the dust collecting electrode plate 4. It also includes two support members 11, which are arranged on two ring beams 12 on the electrostatic precipitator. One end of the suspension beam is slidably connected to one of the ring beams 12 through one support member, and the other end of the suspension beam 9 is connected to another of the ring beams 12 through another support member.

[0061] Based on the above embodiments, Figure 7 As shown, one end of the suspension beam is slidably connected to the ring beam on the electrostatic precipitator through a sliding assembly, and the other end of the suspension beam is fixedly connected to the electrostatic precipitator through a fixing assembly.

[0062] Specifically, one end of the suspension beam 9 is slidably connected to the ring beam 12 on the electrostatic precipitator through a sliding assembly 13. The sliding assembly 13 includes a sliding end limit block 14, a sliding end bolt 15, and a sliding end nut 16. The sliding end limit block 14 is arranged on the top of the support member 11. The sliding end bolt 15 passes through the sliding end limit block 14 and a support member 11, and the upper and lower ends of the sliding end bolt 15 are respectively fixed by the sliding end nut 16. It also includes a sliding end washer 17, which is respectively arranged between the sliding end nut 16 and the sliding end limit block 14, and between the sliding end nut 16 and the support member 11. In this embodiment, two sliding assemblies are selected, and the suspension beam is located between the two sliding assemblies.

[0063] Based on the above embodiments, specifically, Figure 8 As shown, the other end of the suspension beam 9 is fixedly connected to the electrostatic precipitator through a fixing assembly 18, and the fixing assembly 18 includes a fixing end bolt 19 and a fixing end nut 20. The fixing end bolt 19 passes through the bottom plate on the side of the suspension beam 9 and another support member 11, and the upper and lower ends are respectively connected by the fixing end nut 20. A fixing end washer 21 is also included, which is arranged between the fixing end nut 20 and the bottom plate on the side of the suspension beam 9, and between the fixing end nut 20 and the support member 11. In this embodiment, two fixing assemblies are provided, and the two fixing assemblies respectively pass through the bottom plates on both sides of the suspension beam and are connected to the ring beam.

[0064] Based on the above embodiments, specifically, Fig. 9 As shown, one end of the suspension plate 10 is arranged between the suspension beams 9, and the other end of the suspension plate 10 extends to the lower end of the suspension beam 9 and is connected to the dust collecting plate through a connecting piece 22.

[0065] Specifically, Fig. 9 As shown, the connecting member 22 includes a rivet 23, a washer 24 and a round pin steel 25. The rivet 23 passes through the fixing member 26 of the suspension plate 10 and the dust collecting plate and is fixed by the round pin steel 25. A washer 24 is arranged between the round pin steel 25 and the fixing member 26.

[0066] The suspension assembly should not only suspend the dust collecting electrode assembly, but also ensure the internal stability of the entire dust collecting electrode system, so that the dust collecting electrode system as a whole presents a relatively stable cubic structure. The entire structure needs to ensure that the dust collecting electrode system does not fail due to distortion and swinging, which causes deformation of the internal structure and changes in the discharge distance between the negative dust collecting electrodes, during the flow of flue gas in the electric field, the high temperature expansion caused by the flue gas temperature, and the vibration of the equipment caused by operations such as vibration and cleaning. This requires that the dust collecting electrode suspension assembly has a certain strength and rigidity, and a certain ability to resist bending deformation under high temperature conditions.

[0067] The suspension beam 9 is made of alloy steel, which has a large allowable stress at high temperature, a small expansion amount, and is not easy to bend.

[0068] like Figures 7 to 9 As shown, the suspension beam 9 replaces the integrated steel such as I-beam or H-beam with the back-to-back form of channel steel, which increases the welding contact area with the suspension plate 10 without weakening the overall rigidity of the dust collecting pole suspension beam, increases the number of welds, and reduces the potential safety hazard of high temperature weld cracking caused by high temperature;

[0069] The suspension beam 9 and the suspension plate 10 are connected by welding and bolts to provide double protection, thereby improving the safety factor when used under high temperature.

[0070] The suspension beam of the dust collecting electrode provided by the present invention changes the material and structure of the suspension beam, improves the allowable stress of the dust collecting electrode suspension beam at high temperature, and changes the welding form of the single weld between the suspension plate and the dust collecting electrode suspension beam to avoid stress concentration on the single weld, thereby solving the safety hazard caused by the reduction of the allowable stress of the weld at high temperature.

[0071] The collecting electrode suspension beam provided by the present invention is used in an electrostatic precipitator, and its operating temperature is a high temperature exceeding 450°C. The existing technology does not have a collecting electrode suspension beam at this temperature. The suspension beam provided by the present invention suspends the collecting electrode in the electrostatic precipitator to collect dust in the flue gas. At high temperatures, it can prevent the material from expanding. The expansion that cannot be released freely will cause the collecting electrode system to twist, deform and fail.

[0072] Based on the above embodiment, another embodiment is as follows: Fig.10As shown, the rapping and cleaning component 3 includes a rapping motor, a rapping shaft 27 and a rapping hammer 28. The rapping motor is arranged on the shell of the electrostatic precipitator. The rapping shaft is connected to the rapping motor and is arranged inside the shell. A row of limit holes is opened on the rapping shaft 27, which are arranged in an orderly manner in a spiral line around the circumference. The rapping hammer assembly is installed on the rapping shaft through a metal pin. When the rapping shaft rotates, it drives the rapping hammer to rotate. Every time it rotates a certain angle, a rapping hammer falls and hits the pole plate row. One rapping hammer falls in turn and is evenly distributed to 360° of the circumference according to the number of pole plate rows.

[0073] Among them, the installation position of the rapping hammer corresponds to the dust collecting electrode plate row.

[0074] Under high temperature conditions, the yield strength of the shaft decreases after being heated, so it is necessary to select high temperature resistant alloy steel and increase the shaft diameter to 60mm or more. The linear expansion coefficient of the material increases under high temperature, and the shaft will expand due to heat, so the problem of shaft expansion failure needs to be solved.

[0075] The shaft with a length of 12 meters is divided into four equal sections, each section is 4 meters long, and the sections are connected by three couplings 29 in the middle.

[0076] like Fig.11 As shown, in order to release the axial expansion of the shaft, the three couplings 29 are designed with enlarged expansion gaps. The coupling consists of a first coupling 30 and a second coupling 36, and the movable distance between the two couplings is expanded from 20 mm to 30 mm or more, which can fully release the axial expansion of each section of the shaft.

[0077] Fig.12 This is a structural diagram of a rapping hammer. The rapping hammer on the rapping shaft can hit the dust collecting plate through the rotation of the shaft.

[0078] The present invention fully releases the axial expansion of the dust collecting pole vibration cleaning component to prevent the shaft from failing due to high temperature.

[0079] The present invention fully releases the expansion of the dust collecting electrode system through the suspension component, the dust collecting electrode component and the vibration and cleaning component to prevent high-temperature failure.

[0080] The present invention also provides an electrostatic precipitator, such as Fig.13 As shown, it includes a housing 31 and also includes:

[0081] A discharge electrode system 32, which is suspended inside the shell, and the discharge electrode system is not in contact with the shell;

[0082] The dust collecting electrode system 33 is located inside the housing in a suspended manner;

[0083] The discharge electrode system releases negative charge, so that the dust in the flue gas is charged and moves toward the dust collecting electrode system and is adsorbed on the dust collecting electrode system.

[0084] From the side, due to the presence of the built-in ash-sliding slope 34, which is formed by overlapping multiple ash-sliding planes, the overall circular structure in the equipment is changed. The length of the plate needs to be adjusted according to the ash-sliding plane, so that the connecting lines of the plate rows on the ash-sliding slope are parallel to the corresponding ash-sliding planes. Calculate the expansion of the longest plate in the high-temperature electrostatic precipitator at the operating temperature (calculated according to the high-temperature linear expansion coefficient of the corresponding material). This length is the actual length of the theoretical dust collecting plate row at high temperature. The direction of the expansion is vertically downward because the dust collecting pole suspension end is fixed.

[0085] The distance for ash accumulation and a certain margin need to be left on the ash sliding slope, so the length of the dust collecting plate row should ensure that the distance between each row of dust collecting plate rows and the ash sliding plane = the high-temperature expansion of the longest plate + the reserved height for ash sliding surface accumulation + a certain margin. After the dust collecting plate contacts the accumulated ash, the dust accumulation at the contact part cannot slide down the slope well, causing overlap with the discharge electrode system and equipment failure. Example:

[0086] The dust collecting plate is made of 304 stainless steel at high temperature, with an operating temperature of 550°C. The average linear expansion coefficient of 304 stainless steel at 550°C is 18.58 (10-6mm / mm*°C). The longest dust collecting plate is 10m long. Then: the high-temperature expansion of the longest plate = 18.58*10 = 185.8mm; the reserved height for ash sliding surface accumulation is preset to 250mm, and 50mm is reserved. The sum of the three = 485.8mm, rounded = 500mm.

[0087] The connecting lines of the bottom side views of the electrode plate rows on the ash sliding slope are parallel to the corresponding ash sliding planes at a distance of 500 mm, thereby a dust collecting electrode system suitable for a high-temperature electrostatic precipitator with a built-in ash sliding slope can be designed.

[0088] Therefore, the dust collecting electrode system corresponds to the shape of the shell.

[0089] Similarly, the shape of the discharge electrode system that matches the dust collecting electrode system must also correspond to the shape of the shell.

[0090] The soot on the dust collecting electrode can also be vibrated or blown by other vibrating devices or blowing devices to make the dust on the dust collecting electrode system fall off and fall onto the ash sliding slope on the bottom ash sliding plate.

[0091] The dust collecting electrode system adopted by the electric precipitator provided by the present invention is reasonably matched with the interior of the high-temperature electric precipitator and meets the needs of the high-temperature electric precipitator.

[0092] There are other optional embodiments of the present invention, which will not be described in detail here.

[0093] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes, and they can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described herein.
