Description

Technical Field

[0001] This utility model relates to the field of wet electrostatic precipitators, specifically a wet electrostatic precipitator that avoids dust accumulation. Background Technology

[0002] A wet electrostatic precipitator is an electrostatic precipitator that uses water spraying or overflow to form a water film on the surface of the collecting electrode, thereby cleaning the electrode. Wet cleaning can prevent the re-entrainment of settled dust and achieve a high dust removal efficiency.

[0003] In existing technologies, during water-cooled cleaning, the wastewater generated is typically discharged through a T-connector to the air inlet and a drain pipe connected to the T-connector. This method often results in residue buildup at the bottom of the inner wall of the air inlet. As the system is subsequently switched to flue gas drying, this residue and dust clump together and accumulate inside the air inlet, leading to poor airflow over time. Utility Model Content

[0004] The purpose of this utility model is to provide a wet electrostatic precipitator that avoids dust accumulation in order to solve the problems mentioned in the background art.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4 In this embodiment of the present invention, a wet electrostatic precipitator for preventing dust accumulation includes a housing 1, an air outlet 3 installed at the top of the housing 1, an air inlet 2 installed at the bottom of the housing 1, a one-way mechanism installed inside the lower part of the housing 1, a drain pipe 5 provided on the lower part of the outer wall of the housing 1, the input end of the drain pipe 5 being aligned with the inclined lower side of the one-way mechanism, an anode tube 8 installed on the inner wall of the housing 1 above the one-way mechanism, baffles 9 fixedly installed on the upper and lower parts of the outer wall of the anode tube 8 and fixedly connected to the inner wall of the housing 1, a fixing rod 6 fixedly installed on the inner wall of the housing 1 above the anode tube 8, a cathode corona wire 7 extending into the inner cavity of the anode tube 8 fixedly installed on the lower part of the outer periphery of the fixing rod 6, and a spray pipe 4 installed on the inner wall of the housing 1 above the fixing rod 6; the one-way mechanism includes a distributor assembly and a one-way assembly.

[0020] In this embodiment: First, the desulfurized flue gas enters the outer casing 1 through the flue gas channel from the inlet 2, and then passes through the distributor assembly to achieve relatively uniform upward dispersion of the flue gas. The upwardly dispersed flue gas enters the interior of the outer casing 1 through the one-way mechanism and disperses upward from the inner cavities of multiple anode tubes 8. After the device is powered on, the cathode corona wire 7, together with the anode tubes 8, generates a stable high-voltage electrostatic field, adsorbing dust, water droplet aerosols, odors and other substances contained in the flue gas onto the inner wall of the anode tubes 8. After the device has finished operating, the device is powered off, and the water pump connected to the spray pipe 4 is started. The water pump pumps water into the spray pipe 4, and then sprays it downward from the nozzle of the spray pipe 4. The sprayed water can clean the dirt adsorbed on the inner wall of the anode tubes 8. Afterward, the water flows downward along the inner wall of the anode tubes 8 and falls on the top of the one-way mechanism. Finally, the valve on the drain pipe 5 is opened, and the sewage is discharged outward through the drain pipe 5.

[0021] Please refer to this carefully. Figure 2 and Figure 4 The distributor assembly includes a guide plate 10 fixedly installed on the lower part of the inner wall of the housing 1. The top of the guide plate 10 is inclined. A distribution pipe 11 is installed below the guide plate 10 and extends to the top of the guide plate 10. An air outlet chamber 12 is opened at the top of the inner wall of the distribution pipe 11.

[0022] In this embodiment: when the flue gas escapes upward through the distribution pipe 11, the air pressure acts on the one-way component, and the one-way component opens under pressure. Then the gas enters the outer shell 1 through the air outlet 12. After the flue gas stops entering, the one-way component resets. This can prevent water from entering the distribution pipe 11 through the one-way mechanism during the cleaning process, and can better discharge the sewage.

[0023] Please refer to this carefully. Figure 2 and Figure 4 The one-way component includes a blocking ball 13 located above the output end of the air outlet chamber 12. The bottom end of the blocking ball 13 is fixedly connected to a sliding rod 15 that passes through the air outlet chamber 12 and extends into the inner cavity of the distribution pipe 11. A fixing plate 14 is slidably connected to the outer periphery of the sliding rod 15. The outer periphery of the fixing plate 14 is fixedly connected to the inner periphery of the distribution pipe 11. A spring 16 abuts between the protrusion at the bottom end of the sliding rod 15 and the bottom end of the fixing plate 14.

[0024] In this embodiment: after the flue gas passes through the distribution pipe 11, the air pressure acts on the bottom end of the sealing ball 13. At this time, the sealing ball 13 drives the sliding rod 15 to move upward. At this time, the spring 16 is compressed, and the flue gas can overflow upward through the outlet chamber 12. When cleaning stops, the flue gas stops entering. At this time, the spring 16 returns to its original position. The returned spring 16 pulls the sealing ball 13 to block the output port of the outlet chamber 12.

[0025] Please refer to this carefully. Figure 4 The diameter of the sliding rod 15 is smaller than the diameter of the air outlet chamber 12. A sealing ring is fixedly installed at the bottom of the sealing ball 13, and an air hole is opened on the fixing plate 14.

[0026] In this embodiment: This design allows flue gas to effectively escape upwards when the sealing ball 13 is open, and effectively prevents water from entering the distribution pipe 11 when the sealing ball 13 is closed.

[0027] Please refer to this carefully. Figure 4 A triangular plate 17 is fixedly installed on one side of the bottom of the guide plate 10. The end of the triangular plate 17 near the drain pipe 5 is inclined. The lower edge of the inclined surface of the triangular plate 17 is aligned with the lower part of the inner wall of the drain pipe 5. A valve is installed on the drain pipe 5.

[0028] In this embodiment: During cleaning, the sewage falls through the inner cavity of the anode tube 8 onto the top of the guide plate 10, and then falls along the top inclined surface of the guide plate 10 onto the inclined surface of the triangular plate 17. At this time, the sewage is located at the inlet port of the drain pipe 5, which facilitates the effective discharge of sewage.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
