Abstract
Description
Technical Field
[0001] The invention relates to the technical field of electrostatic dust removal, and in particular to an electrostatic dust collector. Background Art
[0002] In order to achieve lower dust concentration emissions, enterprises need better dust removal equipment. In the existing production process, there are many kinds of dust removal equipment. As a common dust treatment equipment, electrostatic precipitator is mostly used to treat dust generated in the daily production of energy industrial enterprises such as thermal power plants. The working principle of the electrostatic precipitator is to use a high-voltage electrostatic field to ionize the dust-containing gas. The dust in the dust-containing gas is separated from the gas under the action of the electric field. The dust combines with the negative ions generated by the discharge electrode (also known as the corona electrode, cathode, negative electrode, etc.) in the electrostatic precipitator and carries negative charge. The negatively charged dust moves to the dust collecting electrode (also known as the anode, positive electrode, etc.) in the electrostatic precipitator under the action of the electric field force, and is finally adsorbed on the surface of the dust collecting electrode, thereby achieving the purpose of dust removal. Among them, the discharge electrode is usually made of metal wires with different cross-sectional shapes, and the dust collecting electrode is usually made of metal plates with different geometric shapes.
[0003] After the electrostatic precipitator has been working for a long time, a large amount of dust will adhere to the surface of the dust collecting electrode and the discharge electrode. In order to make the dust attached to the dust collecting electrode and the discharge electrode fall off as soon as possible so as not to affect the smooth progress of the subsequent electrode discharge process, a corresponding anode rapping device and a cathode rapping device are usually provided in the electrostatic precipitator. Generally speaking, the anode rapping device and the cathode rapping device are either provided at the top of the electrostatic precipitator or at the side of the electrostatic precipitator, so that the rapping device raps the dust on the dust collecting electrode and the discharge electrode from the top or side of the equipment. Specifically, the dust collecting electrode usually includes an anode plate and an anode vibration rod provided at the end of the anode plate, and the discharge electrode usually includes a cathode wire and a frame for fixing the cathode wire, and a cathode vibration rod is provided at the end of the frame; the anode rapping hammer in the anode rapping device and the cathode rapping hammer in the cathode rapping device can both rotate along the circumferential direction of the rapping axis, thereby respectively striking the anode vibration rod and the cathode vibration rod, that is, realizing the rapping operation of the discharge electrode and the dust collecting electrode.
[0004] However, in the actual rapping process, the electrostatic precipitator with this setting mode can only be rapped along the axial direction of the anode rapping rod or the cathode rapping rod due to the relatively simple rapping mode. Therefore, the area near the anode rapping rod and the area near the axial direction of the anode rapping rod in the anode plate, as well as the area near the cathode rapping rod and the area near the axial direction of the cathode rapping rod in the cathode line, usually have less dust adhesion under the rapping of the rapping device. However, for other areas in the anode plate and the cathode line, especially the area in the middle of the anode plate and the cathode line, the above-mentioned rapping device cannot effectively exert a good rapping effect, which is not conducive to cleaning the dust on the dust collecting electrode and the discharge electrode.
[0005] This shows that the prior art needs to be further improved and enhanced. Summary of the invention

DETAILED DESCRIPTION
[0021] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.
[0022] Reference Figure 1-Figure 9 As shown, an embodiment of the present invention provides an electrostatic precipitator, including a body 100, a dust collecting module 200, a discharge module 300 and a cleaning module 400. Specifically, the body 100 has a dust collecting chamber 110, the dust collecting module 200 is located in the dust collecting chamber 110, and the dust collecting module 200 includes an anode plate 210 and a first vibration rod 220 arranged at the top of the anode plate 210; the discharge module 300 is parallel to the dust collecting module 200, the discharge module 300 includes a fixed frame 310 and a cathode line 320 arranged on the fixed frame 310, and the top of the cathode line 320 has a second vibration rod 330; the cleaning module 400 includes a first rapping unit 410 correspondingly arranged above the first vibration rod 220 and a first rapping unit 410 correspondingly arranged above the first vibration rod 220. A second rapping unit 420 above the second vibration rod 330, as well as a third rapping unit 430 and a fourth rapping unit 440; wherein, the first rapping unit 410 and the second rapping unit 420 can contact the first vibration rod 220 and the second vibration rod 330 respectively, and the third rapping unit 430 and the fourth rapping unit 440 are respectively arranged on the side walls of the anode plate 210 and the fixed frame 310, so that the rapping force is transmitted to the anode plate 210 and the cathode line 320 along the axial and radial directions of the first vibration rod 220, and along the axial and radial directions of the second vibration rod 330 respectively.
[0023] It should be noted that the present application does not limit the specific structure and shape of the anode plate 210 and the cathode wire 320. For example, the anode plate 210 can be a rectangular plate with a flat surface, or a plurality of evenly distributed arc flanges can be provided on the surface of the anode plate 210 to increase the surface area of the anode plate 210 to a certain extent, thereby facilitating the improvement of the dust collection amount and dust collection effect of the anode plate 210; the cathode wire 320 can be a fishbone needle wire, a spiral wire, an angle steel barb wire, a tubular barb wire, a star-shaped wire, a sawtooth wire, etc. Different types of cathode wires 320 have different characteristics, and the staff can select the appropriate type of cathode wire 320 according to the actual product design requirements.
[0024] It is understandable that there are usually multiple dust collecting modules 200 and discharge modules 300 in the dust removal chamber 110, and different dust collecting modules 200 and different discharge modules 300 are arranged alternately, that is, the anode plate 210 and the cathode line 320 are arranged adjacent to each other. When the electrostatic precipitator is working, the anode plate 210 and the cathode line 320 are connected to high voltage electricity, so that the area between the anode plate 210 and the cathode line 320 forms a high voltage electric field, so that the dust-containing gas entering the high voltage electric field can be ionized. Among them, according to the different specifications and models of the electrostatic precipitator, the size of the internal high voltage electric field may also be different, so the specific number of dust collecting modules 200 and discharge modules 300, and the specific setting position between the two may also be different, and this application does not limit this.
[0025] The electrostatic precipitator provided by the embodiment of the present invention, firstly, by arranging the first rapping unit 410 above the first vibration rod 220, the first rapping unit 410 can rap the anode plate 210 along the axial direction of the first vibration rod 220; secondly, by arranging the second rapping unit 420 above the second vibration rod 330, the second rapping unit 420 can rap the cathode line 320 along the axial direction of the second vibration rod 330; thirdly, by arranging the third rapping unit 430 on the side wall of the anode plate 210, the third rapping unit 430 can rap the anode plate 210 along the radial direction of the first vibration rod 220; finally, by arranging the fourth rapping unit 440 on the side wall of the fixed frame 310, the fourth rapping unit 440 can rap the cathode line 320 along the radial direction of the second vibration rod 330. Compared with the electrostatic precipitator in the prior art, the equipment provided by the present application can vibrate the anode plate 210 and the cathode line 320 from more directions and more angles, so that the cleaning module 400 can not only effectively vibrate and clean the areas in the anode module and the cathode module close to the first vibration rod 220 and the second vibration rod 330, but can also vibrate the middle area of the anode module and the cathode module to achieve overall vibration of the anode plate 210 and the cathode line 320, thereby helping to improve the cleaning effect of the cleaning module 400 on dust attached to the surface of the anode plate 210 and the cathode line 320.
[0026] In some embodiments, reference Figure 6 and Figure 7As shown, the third rapping unit 430 includes a fixed seat 431, a rotating shaft 432, a roller 433 and a third driving member 434. The fixed seat 431 has a vibration groove (not marked in the figure) and teeth 435 formed inside the vibration groove, and the rotating shaft 432 is rotatably connected to the fixed seat 431; the roller 433 is arranged on the outer side of the rotating shaft 432, and the roller 433 is located in the vibration groove and has a protrusion 436 formed on its surface; the third driving member 434 is transmission-connected to the rotating shaft 432, so that the roller 433 can rotate with the rotation of the rotating shaft 432, and realize the contact and separation between the protrusion 436 and the teeth 435.
[0027] It should be noted that the anode plate 210 in the present application has a relative dust collecting surface (not marked in the figure) and a supporting surface (not marked in the figure), wherein the dust collecting surface is used to absorb dust, and the supporting surface is used to fix the third rapping unit 430. Specifically, by directly setting the fixing seat 431 in the third rapping unit 430 on the supporting surface, the rapping force generated when the protrusion 436 contacts the tooth 435 can be directly transmitted to the dust collecting surface of the anode plate 210, thereby realizing the rapping of the anode plate 210.
[0028] Optionally, there may be multiple protrusions 436 on the surface of the roller 433, and the multiple protrusions 436 are evenly distributed along the circumference of the roller 433. This arrangement enables the multiple protrusions 436 to collide and contact with the teeth 435 in sequence, and enables the third rapping unit 430 to generate intermittent rapping force. Compared with the way in which the third rapping unit 430 continuously generates rapping force, the intermittent rapping force can largely avoid the contamination of the anode plate 210 by secondary dust, thereby helping to improve the cleaning effect of the cleaning module 400 on the anode plate 210. Exemplarily, the protrusions 436 on the surface of the roller 433 may be six, eight, etc., and the present application does not limit the specific number of protrusions 436.
[0029] In addition, the third driving member 434 can be a driving motor, a hydraulic motor, a hydraulic pump, a pneumatic pump, etc., and the present application does not limit the specific type of the third driving member 434. Regarding the transmission connection between the third driving member 434 and the rotating shaft 432, the present application can also have a variety of different implementations. Exemplarily, the third driving member 434 and the rotating shaft 432 can be transmitted by a belt-pulley matching method, or by a gear meshing method, or by a chain-sprocket matching method, or by a gear-rack matching method, etc.
[0030] It should also be noted that in order to further improve the rapping effect of the third rapping unit 430 so that it can evenly rap each area of the anode plate 210, the number of the third rapping unit 430 can be multiple. Preferably, in one anode plate 210, the number of the third rapping unit 430 is configured as three, and the three third rapping units 430 are respectively located at the upper part, the middle part and the lower part of the anode plate 210, so that it can rap the upper part, the middle part and the lower part of the anode plate 210 respectively.
[0031] In some embodiments, continue to refer to Figure 7 As shown, the fixed seat 431 may include a bottom plate 437 connected to the anode plate 210 and a side plate 438 perpendicular to the bottom plate 437, and the bottom plate 437 and the side plate 438 are connected to enclose a vibration groove; and, there may be multiple rotating shafts 432, and the side plate 438 is provided with multiple shaft holes (not marked in the figure), and the multiple rotating shafts 432 cooperate with the multiple shaft holes to realize the rotational connection between the multiple rotating shafts 432 and the fixed seat 431.
[0032] Further, the plurality of rotating shafts 432 are respectively configured as a driving shaft and a driven shaft, one end of the driving shaft is connected to the third driving member 434, and the other end is provided with a driving wheel (not marked in the figure), and one end of the driven shaft is provided with a driven wheel (not marked in the figure) corresponding to the driving wheel. In addition, the third rapping unit 430 may also include a belt (not marked in the figure), which is respectively matched with the driving wheel and the driven wheel to realize the transmission connection between the third driving member 434 and the rotating shaft 432.
[0033] The transmission connection between the third driving member 434 and the rotating shaft 432 is realized through the cooperation between the belt and the active wheel and the driven wheel. This transmission method has a simple structure, smooth transmission, and can mitigate impact and absorb vibration, thereby preventing the rapping force from being transmitted to the third rapping unit 430 itself to a certain extent, thereby facilitating the long-term stable operation of the third rapping unit 430.
[0034] Furthermore, there are two rollers 433 on the outside of any rotating shaft 432, and the two rollers 433 are respectively arranged at intervals along the axial direction of the rotating shaft 432. The two rollers 433 arranged on the outside of the same rotating shaft 432 can enhance the rapping effect of the third rapping unit 430, thereby facilitating the uniform transmission of the rapping force to the anode plate 210.
[0035] It is understandable that, in addition to being set to two, the rollers 433 on the outside of the rotating shaft 432 can also be set to other numbers according to different user needs, such as one or three, etc. The present application does not limit the number of rollers 433 on the rotating shaft 432.
[0036] In some embodiments, reference Figure 8-Figure 11As shown, the fourth rapping unit 440 includes a mounting seat 441, a fourth driving member 442, a guide rod 443 and an elastic member 444. Specifically, the mounting seat 441 is arranged on the inner wall of the body 100, and has a guide groove (not marked in the figure) and a fixing plate 445 arranged in the guide groove, and the fixing plate 445 is provided with a guide hole (not marked in the figure); a cam 446 is arranged on the driving shaft (not marked in the figure) of the fourth driving member 442, and a push block 447 matching the guide groove is arranged at the first end of the guide rod 443, and the second end can pass through the guide hole to contact the cam 446; the elastic member 444 is sleeved on the outer side of the guide rod 443, and the elastic member 444 is respectively connected to the push block 447 and the fixing plate 445; wherein, under the drive of the fourth driving member 442 and the elastic force of the elastic member 444, the push block 447 can move along the axial direction of the guide rod 443, so that the push block 447 and the fixing frame 310 are in contact or separated. Optionally, the fourth driving component 442 may be a driving motor, a hydraulic motor, a hydraulic pump, a pneumatic pump, etc. The present application does not limit the specific type of the fourth driving component 442 .
[0037] In the fourth beating unit 440, when the cam 446 contacts the second end of the guide rod 443, the cam 446 drives the guide rod 443 to move along its axial direction to extend out of the mounting seat 441, so that the push block 447 can slide in the guide groove and finally achieve contact between the push block 447 and the fixed frame 310; when the cam 446 is separated from the second end of the guide rod 443, the guide rod 443 shrinks to the mounting seat 441 under the elastic force of the elastic member 444, and the push block 447 also moves toward the cam 446 along the extension direction of the guide groove, and the push block 447 is separated from the fixed frame 310.
[0038] By setting the fourth rapping unit 440, the device can perform a rapping operation on the fixed frame 310, so that the rapping force can be transmitted to the cathode wire 320, thereby cleaning the dust attached to the surface of the cathode wire 320. This setting method can further improve the cleaning effect of the device on the cathode wire 320, thereby facilitating the long-term stable operation of the device.
[0039] Furthermore, the push block 447 is provided with an avoidance groove (not marked in the figure), and the shape of the avoidance groove is adapted to the profile of the side wall of the fixed frame 310. The setting of the avoidance groove in the push block 447 can reduce the transition impact of the push block 447 on the fixed frame 310 during the operation of the fourth rapping unit 440, thereby facilitating the structural stability of the fixed frame 310 and avoiding deformation of the fixed frame 310 to a certain extent. In addition, the setting of the avoidance groove enables the structure of the push block 447 to better adapt to the profile of the side wall of the fixed frame 310, thereby facilitating the improvement of the rapping effect of the fourth rapping unit 440.
[0040] In some embodiments, reference Figure 1 and Fig.12 As shown, the first rapping unit 410 includes a first rapping shaft 411 and a first hammer 412 sleeved on the outside of the first rapping shaft 411, and a first driving member 413 connected to the end of the first rapping shaft 411; the second rapping unit 420 includes a second rapping shaft 421 and a second hammer 422 sleeved on the outside of the second rapping shaft 421, and a second driving member 423 connected to the end of the second rapping shaft 421. The first hammer 412 and the second hammer 422 can rotate along the axial direction of the first rapping shaft 411 and the second rapping shaft 421, respectively, to achieve contact or separation between the first hammer 412 and the first vibration rod 220, and the second hammer 422 and the second vibration rod 330.
[0041] Furthermore, there are multiple first vibration rods 220 , multiple second vibration rods 330 , multiple first vibration hammers 412 and multiple second vibration hammers 422 , and the multiple first vibration hammers 412 correspond to the multiple first vibration rods 220 , respectively, and the multiple second vibration hammers 422 correspond to the multiple second vibration rods 330 , respectively.
[0042] It is understandable that in order to avoid the secondary dust that may be generated in the dust removal chamber 110 during the operation of the first rapping unit 410 and the second rapping unit 420. Preferably, the multiple first vibrating hammers 412 are arranged at different angles on the first rapping shaft 411, and the multiple second vibrating hammers 422 are arranged at different angles on the second rapping shaft 421, so that the multiple first vibrating hammers 412 respectively and successively hit the multiple first vibration rods 220, and the multiple second vibrating hammers 422 respectively and successively hit the multiple second vibration rods 330; in other words, when the multiple first vibrating hammers 412 and the multiple second vibrating hammers 422 are working, there is a certain time interval between two adjacent striking actions, so as to realize the intermittent vibration of the first rapping unit 410 and the second rapping unit 420, and then help to improve the vibration effect of the first rapping unit 410 and the second rapping unit 420.
[0043] Exemplarily, when there are three first vibrating hammers 412 on the first vibrating shaft 411 and three second vibrating hammers 422 on the second vibrating shaft 421, along the axial direction of the first vibrating shaft 411 and the second vibrating shaft 421, the angles between the three first vibrating hammers 412 are 120°, and the angles between the three second vibrating hammers 422 are also 120°.
[0044] In some embodiments, continue to refer to Fig.12 As shown, the first rapping unit 410 also includes a first support 414 disposed on the top of the body 100, and the first support 414 cooperates with the first rapping shaft 411; the second rapping unit 420 also includes a second support 424 disposed on the top of the body 100, and the second support 424 cooperates with the second rapping shaft 421.
[0045] The setting of the first support 414 and the second support 424, on the one hand, can support and fix the first rapping shaft 411 and the second rapping shaft 421, thereby ensuring the precise rapping coordination between the first vibrating hammer 412 and the first vibration rod 220, and between the second vibrating hammer 422 and the second vibration rod 330; on the other hand, the first support 414 and the second support 424 also have a certain degree of vibration reduction and buffering effect, thereby preventing the rapping force generated by the first rapping unit 410 and the second rapping unit 420 from being transmitted to the machine body 100, thereby ensuring the structural stability of the machine body 100 and reducing the noise generated during the operation of the equipment.
[0046] In the description provided herein, a large number of specific details are described. However, it is understood that embodiments of the present invention can be practiced without these specific details.
