Description

Technical Field

[0001] The utility model relates to the technical field of electrostatic precipitators, in particular to an offline zero-wind-speed vibration-cleaning electrostatic precipitator. Background Art

[0002] Electrostatic precipitator is an essential supporting equipment for thermal power plants. Its function is to remove particulate dust from the flue gas emitted by coal-fired or oil-fired boilers to reduce the amount of dust discharged into the atmosphere, which can improve environmental pollution and improve air quality.

[0003] However, the existing electrostatic precipitator requires a large spacing between the internal electrode plates, which makes the electrode plates take up more space when arranged, so the volume of the traditional electrostatic precipitator is designed to be larger, resulting in the electrostatic precipitator requiring a larger site when put into use, which invisibly increases the use cost of the electrostatic precipitator; in addition, when the dust particles on the electrode plates of the existing electrostatic precipitator are vibrated by the vibrating device, the dust particles that fall off the surface of the electrode plates are likely to float in an undirected manner in the precipitator to form dust, and the dust is likely to continue to float in the precipitator, resulting in the dust particles on the electrode plates being difficult to enter the ash bin and be collected after being vibrated, affecting the dust removal efficiency of the electrostatic precipitator. Utility Model Content

[0004] The purpose of the utility model is to provide an off-line zero-wind-speed vibration-cleaning electrostatic precipitator to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: an offline zero-wind-speed vibration and dust-cleaning electrostatic precipitator, comprising a shell, vibration mechanisms are installed on both sides of the top of the shell, the front cover of the shell is provided with a smoke inlet, the bottom end of the shell is fixedly connected to an ash bin, the back cover of the shell is provided with a smoke outlet, both sides of the inner top of the shell are fixedly connected to a first cross bar, both sides of the inner bottom of the shell are fixedly connected to a second cross bar, the bottom end of the first cross bar and the top end of the second cross bar are clamped with a vertical bar, the outer wall of the vertical bar is fixedly connected to two card plates, one side wall of the card plate is clamped with an electrode plate, the top of the ash bin is fixedly connected to a module, the top of the module is provided with a plurality of negative pressure air ports, and the outer wall of the ash bin is fixedly installed with an air pump.

[0011] Preferably, the negative pressure air port is communicated with the interior of the ash bin, and the smoke inlet and outlet ducts and the ash bin are all communicated with the interior of the shell.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. This offline zero-wind-speed vibration-cleaning electrostatic precipitator uses a first horizontal bar, a second horizontal bar, a vertical bar and a card plate to arrange the electrode plates in the electrostatic precipitator through the insulating card plate in a structural form similar to a screen connection. Compared with the parallel arrangement of traditional electrode plates, the overall volume of the electrostatic precipitator can be reduced, effectively reducing the space required for the site when the electrostatic precipitator is put into use, thereby helping to save the use cost of the electrostatic precipitator.

[0014] 2. This offline zero-wind-speed vibration-cleaning electrostatic precipitator uses modules, negative-pressure air ports and air pumps to enable the electrode plates on the electrostatic precipitator to generate several negative-pressure air intakes at the junction of the ash bin and the inside of the precipitator after the vibration step is completed. This allows the dust particles that are vibrated off the electrode plates to be quickly collected into the ash bin through the negative-pressure air ports, thereby reducing the probability of dust generation in the precipitator, accelerating the collection speed of dust particles in the ash bin and reducing the adverse effects on the dust removal efficiency of the electrostatic precipitator.

[0024] like Figures 1 to 5As shown, the offline zero-wind-speed vibration and dust-cleaning electrostatic precipitator of this embodiment includes a shell 1, and vibration mechanisms 2 are installed on both sides of the top of the shell 1, the front cover of the shell 1 is provided with an inlet pipe 3, the bottom end of the shell 1 is fixedly connected to the ash bin 4, the back cover of the shell 1 is provided with an outlet pipe 6, both sides of the inner top of the shell 1 are fixedly connected with a first cross bar 8, both sides of the inner bottom of the shell 1 are fixedly connected with a second cross bar 12, the bottom end of the first cross bar 8 and the top of the second cross bar 12 are clamped with a vertical bar 10, the outer wall of the vertical bar 10 is fixedly connected with two clamping plates 16, and one side wall of the clamping plate 16 is clamped with an electrode plate 11, the top of the ash bin 4 is fixedly connected with a module 13, the top of the module 13 is provided with a plurality of negative pressure air ports 17, and the outer wall of the ash bin 4 is fixedly installed with an air pump 5.

[0025] Specifically, the shell 1 is welded from a steel structure, and its volume is one-third of the volume of a traditional electrostatic precipitator shell 1. The rapping mechanism 2 includes a vibration motor and other components that assist in completing the rapping action. A smoke inlet is provided on the front of the smoke inlet 3, and a smoke outlet is provided on the back of the smoke outlet 6. The diameter of the smoke inlet is larger than that of the smoke outlet to extend the residence time of the flue gas in the dust collector. The function of the first cross bar 8 and the second cross bar 12 is to fix the two ends of the vertical bar 10 so that the card plate 16 on the vertical bar 10 can be fixed in the shell 1, so that the card plate 16 can fix the electrode plate 11 in the shell 1 in the form of a screen structure, thereby realizing the rearrangement of the electrode plate 11 in the shell 1 and optimizing the arrangement of the electrode plate 11. The card plate 16 is made of an insulated The module 13 is made of an insulating material so that each electrode plate 11 can independently generate an electric field, reducing the interference between the electrode plates 11. The module 13 is a plate-like structure with an inverted "trapezoidal" cross-section, so that the opening at the top of the module 13 is larger than the negative pressure air port 17 at the bottom, so that the air flow speed at the bottom of the module 13 is greater than the air flow speed at the top opening, so that the dust particles near the top of the module 13 can be sucked into the ash bin 4 through the faster negative pressure air flow, thereby accelerating the ash bin 4 to collect the dust particles that are vibrated off from the electrode plates 11. The negative pressure air port 17 can generate negative pressure inside and at the top of the module 13, thereby realizing negative pressure collection of dust particles. The air pump 5 can draw out the air in the ash bin 4, so that negative pressure can be formed in the ash bin 4.

[0026] Furthermore, an exciting hammer 9 is engaged at the output end of the vibrating mechanism 2, and the exciting hammer 9 is movably connected to the electrode plate 11. The exciting hammer 9 can transmit the vibration generated by the vibrating mechanism 2 to the electrode plate 11, so that the electrode plate 11 transmits the resonance generated by the vibration through the vertical rod 10 and the first cross bar 8 and the second cross bar 12, thereby realizing the vibrating of multiple electrode plates 11.

[0027] Furthermore, a first door panel 7 is installed at the smoke inlet of the smoke inlet 3, and a second door panel 15 is installed at the smoke outlet of the smoke outlet 6. After the electrostatic precipitator is powered off and kept offline, the first door panel 7 and the second door panel 15 can close the openings of the smoke inlet 3 and the smoke outlet 6, so that external airflow cannot enter the interior of the dust collector, thereby keeping the interior of the dust collector well sealed, thereby achieving zero wind speed inside the electrostatic precipitator during vibration.

[0028] Furthermore, a connecting pipe passes through the top of the air pump 5, which is connected to the ash bin 4. A dustproof net 14 is installed at the junction of the connecting pipe and the ash bin 4. After the air pump 5 is powered on, the air in the ash bin 4 is sucked away through the connecting pipe, so that negative pressure is generated in the ash bin 4. The dustproof net 14 can prevent dust particles from being sucked into the air pump 5 to ensure the normal operation of the air pump 5.

[0029] Furthermore, a scraper is movably connected to one side wall of the dustproof net 14, and the scraper is engaged with the output end of the driving mechanism fixedly installed in the ash bin 4. The function of the scraper is to clean the impurities on the dustproof net 14 to ensure that the air pump 5 draws the air out of the ash bin 4, thereby achieving a negative pressure environment in the ash bin 4.

[0030] Furthermore, the module 13 is located below the electrode plate 11, and the module 13 is fixedly connected to the outer shell 1 through the ash bin 4. The opening at the top of the module 13 faces the electrode plate 11, so that the dust separated from the electrode plate 11 by vibration can be sucked downward along the surface of the electrode plate 11, thereby facilitating the rapid collection of dust particles by the ash bin 4.

[0031] Furthermore, the negative pressure air port 17 is connected to the interior of the ash bin 4, and the inlet duct 3, the outlet duct 6 and the ash bin 4 are all connected to the interior of the outer shell 1. The negative pressure generated inside the ash bin 4 can generate negative pressure at the top of the module 13 through the negative pressure air port 17, thereby realizing that dust particles are quickly sucked into the interior of the ash bin 4 through the negative pressure.

[0032] The method of use of this embodiment is as follows: when using the offline zero wind speed vibration cleaning electrostatic precipitator, it is necessary to first connect the electrostatic precipitator to the power supply and make the internal electrical appliances powered on and running, then the flue gas will enter the interior of the shell 1 through the inlet pipe 3, and then pass through the electrode plate 11, so that the dust particles in the flue gas are adsorbed on the electrode plate 11, and then the flue gas will be discharged from the outlet pipe 6. When it is necessary to vibrate the dust particles adsorbed on the electrode plate 11, it is necessary to close the first door panel 7 and the second door panel 15, so that the inlet pipe 3 and the outlet pipe 6 are closed, so that The interior of the shell 1 is kept at a zero wind speed state, and then the vibration mechanism 2 is started, so that the exciting hammer 9 vibrates the electrode plate 11, so that the dust particles on the electrode plate 11 are separated from the electrode plate 11, and then the air pump 5 is started to extract the air inside the ash bin 4, so that a negative pressure is generated in the ash bin 4. At this time, the top of the module 13 will also generate some small negative pressures through the negative pressure air port 17, and the dust particles separated from the electrode plate 11 are sucked by negative pressure, so that the dust particles are quickly sucked into the ash bin 4 through the module 13 for collection.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
