Abstract
Description
Technical Field
[0001] The utility model relates to a dust collector, in particular to a post-electric field dust vibration structure. Background Art
[0002] Bag dust collectors, cyclone dust collectors, electrostatic precipitators, wet dust collectors and composite dust collectors are the main dust removal equipment on the market. Electrostatic precipitators are essential supporting equipment for thermal power plants. Electrostatic precipitators ionize gases through discharge at the discharge electrode, and particulate pollutants acquire electron charge. The charged particulate pollutants then move to the collecting electrode and deposit on the collecting electrode plate. Finally, the particulate pollutants on the collecting electrode are removed into the ash hopper to achieve the purpose of removing particulate pollutants in the flue gas. Electrostatic precipitators have the advantages of high dust removal efficiency, small pressure loss, low energy consumption and good applicability. Their function is to remove particulate smoke in the flue gas emitted by stoves or oil-fired boilers, thereby greatly reducing the amount of smoke discharged into the atmosphere.
[0003] An important reason for the poor dust removal effect of the original electrostatic precipitator is the unsatisfactory vibration effect. This is because the transmission of vibration force to the anode plate decays quickly during vibration, and the normal vibration acceleration value generated is small, making it difficult to clean the dust thoroughly. However, if the vibration is strong, local deformation of the plate will occur. If the vibration force is too small, the cleaning will not be thorough, resulting in a decrease in the dust removal efficiency of the electrostatic precipitator after the equipment has been used for a period of time. Utility Model Content
[0004] The utility model provides a post-electric field dust vibration structure, which solves the problem that the vibration attenuation is fast when the electric field height of the original electrostatic precipitator is too high.
[0005] The utility model is achieved in this way:
[0006] A post-electric field dust vibration structure, comprising: the dust vibration structure is arranged in the final electric field, the final electric field is composed of a plurality of grid structures, the grid structure is composed of a plurality of metal grid plates, the metal grid plates include two metal clamping plates, and a wave vibration component is installed between the two metal clamping plates;
[0007] The wave vibration component includes an interlayer cavity vertically sandwiched between the two metal clamps, a accommodating cavity opened at the midline position of the interlayer cavity, a polarization axis arranged in the accommodating cavity and passing through the interlayer cavity, a power component arranged on the polarization axis, a plurality of paddles arranged on the outside of the polarization axis, a plurality of baffles corresponding to the paddles welded in the interlayer cavity, and when the power component drives the polarization axis to rotate, the paddles hit the baffles to make the accommodating cavity for installing the baffles and the two metal clamps vibrate.
[0008] As a further improvement, the top and bottom of the accommodating cavity are both provided with an intercepting tube, the inner diameter of the intercepting tube is larger than the diameter of the polarization axis, and the inner side of the intercepting tube is filled with a sponge attached to the outer side of the polarization axis.
[0009] As a further improvement, the paddle includes a first paddle welded on the outside of the polarization axis, a receiving chamber opened in the first paddle, a second paddle slidably arranged in the receiving chamber, and an elastic member connected between the second paddle and the first paddle.
[0010] As a further improvement, the baffle includes a pre-fixed seat welded in the interlayer cavity, and a baffle welded on the pre-fixed seat, and when the paddle rotates, the first paddle or the second paddle hits the baffle.
[0011] As a further improvement, the power assembly includes a first servo motor fixedly connected to the top of the polarization axis, and a second servo motor fixedly connected to the bottom of the polarization axis, and the first servo motor and the second servo motor rotate in opposite directions.
[0012] As a further improvement, it also includes a disturbance component, which is arranged on the side of the grille structure. The disturbance component includes a clamping component that cooperates with the metal grille plate, and a pushing member for driving the clamping component to reciprocate. The pushing member is electrically connected to the power component. After the power component is turned off, the pushing member starts with a delay and pushes the clamping assembly to clamp onto the metal grille plate to fix it.
[0013] As a further improvement, the clamping assembly includes a transverse frame of the same length as the grille structure, and a plurality of U-shaped buckles locked on the transverse frame, the transverse frame is fixedly connected to the pushing member, the U-shaped buckles correspond one-to-one with the metal grille plate and are clamped on the metal grille plate after the pushing member is pushed out.
[0014] The beneficial effects of the utility model are:
[0015] After the final electric field has been used for a period of time, it is difficult to transmit the vibration force to the end farther from the striking point during vibration because the adsorbed particles have a certain viscosity and the height of the electric field is relatively high. In the attenuation process, it is easy to cause the far end to not be thoroughly vibrated, which in turn leads to a significant decrease in the dust removal efficiency of the electrostatic precipitator. In this regard, the present invention proposes to change the setting of the traditional single-layer metal anode plate, and instead set two metal clamps, and set a wave vibration component between the two metal clamps. By designing a polarization axis that is equal to the length of the metal clamps, the paddle plate will be driven to hit the baffle plate during the rotation of the polarization axis. Since the baffle plates are evenly distributed in the accommodating cavity, the entire interlayer cavity will be hit during the rotation of the polarization axis to vibrate it, and then the metal clamp connected to it will also vibrate, allowing the particles adhering to it to fall into the cleaning hopper for unified treatment, so that the entire metal clamp can be evenly vibrated, so that the smoke ash at various positions on the metal clamp can be shaken off, and the cleaning is more thorough.
[0016] After the vibration process begins, continuous vibration is generally required, and the smoke and dust can only be completely knocked off after multiple vibrations. However, after one vibration, the entire metal clamp needs to experience a period of attenuation after the initial vibration, and it is necessary to wait for a period of time before the next knocking can be performed (if continuous knocking has a worse effect), which will lengthen the entire vibration cycle. In this regard, the present invention also proposes to set a disturbance component on the side of the grille structure. After one knocking of the structure, the push member is started with a delay, so that the push member pushes out the clamping component, so that the clamping component clamps the metal clamp to prevent it from shaking in a small range. At the same time, it withdraws immediately after the metal clamp is stable, and the power component is started again. The cleaning process in the final electric field can be completed in a short time, so that normal dust removal action can continue. BRIEF DESCRIPTION OF THE DRAWINGS

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.
[0025] Reference Figure 1 to Figure 5 As shown, a post-electric field dust vibration structure includes: the dust vibration structure is arranged in the final electric field, the final electric field 10 is composed of a plurality of groups of grid structures, the grid structure is composed of a plurality of metal grid plates 11, the metal grid plates 11 include two metal clamping plates 111, and a wave vibration component is installed between the two metal clamping plates 111; the wave vibration component includes an interlayer cavity 21 vertically clamped between the two metal clamping plates 111, a receiving cavity opened at the midline position of the interlayer cavity 21, a polarization axis 23 arranged in the receiving cavity and passing through the interlayer cavity 21, a power component arranged on the polarization axis 23, a plurality of paddles 231 are arranged on the outside of the polarization axis 23, a plurality of baffles 211 corresponding to the paddles 231 are welded in the interlayer cavity 21, and when the power component drives the polarization axis 23 to rotate, the paddles 231 are made to hit the baffles 211 to make the receiving cavity for installing the baffles 211 and the two metal clamping plates 111 vibrate.
[0026] During the dust removal process, the flue gas source enters from the air inlet pipe, passes through the front-stage electric field to adsorb coarse particles, then enters the final-stage electric field to adsorb fine particles, and finally is discharged from the outlet pipe.
[0027] After the final electric field 10 has been used for a period of time, it is difficult to transmit the vibration force to the end farther from the striking point during vibration because the particles adsorbed therein have a certain viscosity and the height of the electric field is relatively high. In the process of attenuation, it is easy to cause the far end to fail to be thoroughly vibrated, which in turn leads to a significant decrease in the dust removal efficiency of the electrostatic precipitator. In this regard, the present invention proposes to change the setting of the traditional single-layer metal anode plate and instead set two metal clamping plates 111, and set a wave vibration component between the two metal clamping plates 111, so as to The design of the long polarization axis 23 will drive the paddle 231 to hit the baffle 211 during the rotation of the polarization axis 23. Since the baffle 211 is evenly distributed in the accommodating cavity, the polarization axis 23 will hit the entire interlayer cavity 21 to vibrate during the rotation of the polarization axis 23, and then the metal clamp 111 connected thereto will also vibrate, allowing the particles adhering to it to fall into the cleaning hopper for unified treatment, so that the entire metal clamp 111 can be evenly vibrated, and the soot on various positions of the metal clamp 111 can be shaken off, and the cleaning is more thorough.
[0028] In order to prevent particles in the smoke from entering the accommodating chamber and interfering with the normal cooperation between the paddle 231 and the baffle 211, an intercepting tube 24 is provided at the top and bottom of the accommodating chamber. The inner diameter of the intercepting tube 24 is larger than the diameter of the polarization axis 23, and the inner side of the intercepting tube 24 is filled with a sponge that fits the outer side of the polarization axis 23. The sponge in the intercepting tube 24 can allow the polarization axis 23 to pass normally without affecting the setting of the polarization axis 23.
[0029] During the long-term slapping process, the baffle 211 will inevitably deform, causing it to move away from the paddle 231, so that the paddle 231 can no longer knock down the baffle 211. In this regard, the paddle 231 includes a first paddle 2311 welded to the outside of the polarization axis 23, a receiving chamber 2312 opened in the first paddle 2311, a second paddle 2313 slidably arranged in the receiving chamber 2312, and an elastic member 2314 connected between the second paddle 2313 and the first paddle 2311. When the polarization axis 23 rotates, the paddle 2313 will be The second paddle 2313 is swung out so that the second paddle 2313 can touch the baffle 211. In the initial stage, since the baffle 211 has not been deformed at this time, the first paddle 2311 hits the baffle 211 before the second paddle 2313 is swung out of the accommodating chamber 2312 of the first paddle 2311. After the baffle 211 is deformed, the second paddle 2313 replaces the first paddle 2311 to play the role of hitting. In this embodiment, the elastic member 2314 can be a spring, which will be stretched when rotating, and the second paddle 2313 will be retracted when not rotating.
[0030] In order to prevent the baffle 211 from being easily deformed, the baffle 211 includes a pre-fixed seat 2111 welded in the interlayer cavity 21, and a baffle 2112 welded on the pre-fixed seat 2111. When the paddle 231 rotates, the first paddle 2311 or the second paddle 2313 hits the baffle 2112. The pre-fixed seat 2111 welded in advance makes the welding surface of the paddle 231 larger and more stable.
[0031] During the rotation stage of the polarization axis 23, the polarization axis 23 does not rotate in one direction blindly. After being continuously flapped for a period of time, it needs to rotate in the opposite direction so that the coordination time between the paddle 231 and the baffle 211 can be longer. Therefore, the power assembly includes a first servo motor 251 fixedly connected to the top of the polarization axis 23, and a second servo motor 252 fixedly connected to the bottom of the polarization axis 23. The rotation directions of the first servo motor 251 and the second servo motor 252 are opposite. Through the two groups of servo motors with different directions, the activity direction of the polarization axis 23 is more flexible.
[0032] After the vibration process begins, continuous vibration is generally required, and the smoke and dust can be completely knocked off only after multiple vibrations. However, after one vibration, the entire metal clamp 111 needs to experience a period of attenuation after the initial vibration, and it is necessary to wait for a period of time before the next knocking can be performed (if continuous knocking has a worse effect), which will lengthen the entire vibration cycle. In this regard, the present invention also proposes to set a disturbance component on the side of the grid structure. After one knocking of the structure, the push member 32 is started with a delay, so that the push member 32 pushes out the clamping component 31, so that the clamping component 31 clamps the metal clamp 111, so that it no longer shakes in a small range. At the same time, after the metal clamp 111 is stable, it is immediately withdrawn and the power component is started again. The cleaning process in the final electric field 10 can be completed in a short time, so that normal dust removal action can continue.
[0033] Specifically, the clamping assembly 31 includes a transverse frame 311 of the same length as the grille structure, and a plurality of U-shaped buckles 312 locked on the transverse frame 311. The transverse frame 311 is fixedly connected to the pushing member 32. The U-shaped buckles 312 correspond to the metal grille plate 11 one by one and are clamped on the metal grille plate 11 after the pushing member 32 is pushed out. The opening of the U-shaped buckle 312 is slightly larger than the metal grille plate 11, so it can be better embedded when cooperating with the metal grille plate 11. The metal grille plate 11 can quickly calm down after contacting with the U-shaped buckle 312 and no longer jitters at a low frequency.
[0034] The above description is only the preferred implementation of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
