Description

Technical Field

[0001] This utility model belongs to the field of electrostatic precipitator technology, specifically relating to a structure for preventing condensation on the discharge electrode of an electrostatic precipitator. Background Technology

[0002] An electrostatic precipitator, also known as an electrostatic dust collector or electrostatic precipitator, is a device that uses electrostatic force to remove suspended particles from the air, such as flue gas and industrial dust.

[0003] Electrostatic precipitators (ESPs) operate on the principle of corona discharge and electrostatic fields. They typically consist of two parts: a discharge electrode (cathode) and a collecting electrode (anode). During operation, a high-voltage direct current is passed through the discharge electrode, creating a strong electric field that charges airborne particles. Under the influence of this electric field, the charged dust particles are attracted to and adsorbed onto the surface of the grounded collecting electrode. Subsequently, periodic mechanical vibration or water washing removes the adsorbed dust, which is then collected in the dust hopper.

[0004] However, the surface of the discharge electrode is easily affected by temperature changes. When the temperature drops below the dew point, condensation will occur on its surface. This condensation will have adverse effects on the discharge electrode, such as causing the electrode surface to become damp and reducing its insulation performance, which in turn will affect the normal operation of the electrostatic precipitator and reduce the dust removal efficiency.

[0005] In view of this, we provide a structure to prevent condensation on the discharge electrode of an electrostatic precipitator. Utility Model Content

[0011] As the utility model prevents electric precipitator discharge electrode dew structure optimal, the top of shell is connected with lug, the surface of lug is rotatably connected with limit board.

[0012] As the utility model prevents electric precipitator discharge electrode dew structure optimal, the recess of lug is matched with limit board, and the limit board is fixedly connected in the recess of lug by the fixed pin.

[0013] As the utility model prevents electric precipitator discharge electrode dew structure optimal, the lateral wall of shell is installed with temperature monitor, and the inside of shell is connected with temperature measuring probe, and the temperature measuring probe is installed in the inside of shell away from blower mechanism.

DETAILED DESCRIPTION

[0022] The technical scheme in the embodiments of the utility model will be apparently and completely described in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the range protected by the utility model.

[0023] Embodiment one

[0024] Please refer to Figures 1-4 The utility model provides the following technical scheme: prevent the electrode condensation structure of electric dust collector discharge, including electrode chamber 1 and the anti-condensation mechanism 2 of assembly in the electrode chamber 1 side wall, electrode chamber 1 is by chamber shell 101, cathode 102 and anode 103 are composed, cathode 102 and anode 103 are assembled in chamber shell 101, anti-condensation mechanism 2 is by shell 201, heating sheet 202, blowing mechanism 203 are composed, blowing mechanism 203 is by motor 2001 and fan blade 2002 are composed.

[0025] In the preferred embodiment, the fan blade 2002 is rotatably connected to the inside of the shell 201 by the motor 2001, and the motor 2001 is assembled on the side wall of the shell 201.

[0026] In the preferred embodiment, the dust screen 4 is inserted into the inside of the shell 201, the dust screen 4 is made of metal material, and the dust screen 4 is located between the heating sheet 202 and the blowing mechanism 203, and the air inlet hole 3 is formed in the side wall of the shell 201.

[0027] In the preferred embodiment, the protruding block 5 is connected to the top end of the shell 201, and the limiting plate 6 is rotatably connected to the surface of the protruding block 5.

[0028] In the preferred embodiment, the recessed block 7 is connected to the top end of the shell 201, and the fixing pin 8 is connected to the top end of the recessed block 7.

[0029] In the preferred embodiment, the recess of the recessed block 7 is matched with the limiting plate 6, and the limiting plate 6 is fixedly connected to the inside of the recess of the recessed block 7 by the fixing pin 8.

[0030] In the embodiment, the anti-condensation mechanism 2 is tightly fitted on the side wall of the electrode chamber 1 when installed in the inner core position of the electric dust collector. Once the heating sheet 202 is powered on, hot air is generated quickly. Then, the motor 2001 is started when powered on, and the output shaft drives the fan blade 2002 to rotate, thereby driving the air flow. The air flow is heated by the heating sheet 202 and blown into the electrode chamber 1. With the continuous injection of hot air, the temperature of the electrode chamber 1 is significantly increased, thereby greatly reducing the risk of condensation on the surface of the cathode 102 due to low temperature.

[0031] At the same time, the air flow caused by the rotation of the fan blade 2002 allows external air to continuously enter the inside of the shell 201 through the air inlet hole 3. In this process, the dust in the air is effectively blocked by the dust screen 4, preventing dust from entering the electrode chamber 1 and ensuring the cleanliness of the electrode chamber 1 and the stable operation of the electric dust collector, thereby improving the overall dust removal efficiency and equipment service life.

[0032] When the dust screen 4 is clogged due to dust accumulation, the user only needs to simply pull out the fixing pin 8 from the top end of the recessed block 7, then rotate the limiting plate 6 to easily move it out of the notch of the recessed block 7, and move it away from the top of the dust screen 4. Then, the user can easily pull out the dust screen 4 from the shell 201 for replacement or cleaning of the clogged dust screen 4. This ingenious design greatly facilitates the maintenance operation of the dust screen 4.

[0033] Example Two

[0034] Please refer to Figures 1-4 , the side wall of the shell 201 is provided with a temperature monitor 9, and the inside of the shell 201 is connected with a temperature measuring probe 10 installed inside the shell 201 away from the air blowing mechanism 203.

[0035] In the embodiment, according to the description in Example One, the temperature measuring probe 10 and the temperature monitor 9 can effectively monitor the temperature of the hot air when the hot air flows, facilitating accurate regulation and control of the working efficiency of the heating sheet 202 to ensure the anti-condensation effect. The temperature monitor 9 and the temperature measuring probe 10 are one device, and the model is TKA-550K ASONE high-precision digital temperature controller.

[0036] In summary, according to the description in Examples One and Two, the anti-condensation mechanism 2 uses the heating sheet 202 and the air blowing mechanism 203 to blow hot air into the electrode chamber 1 to increase the temperature and reduce the risk of condensation on the cathode 102. The temperature monitor 9 and the temperature measuring probe 10 monitor the temperature in real time to ensure accurate regulation and control of the efficiency of the heating sheet 202. At the same time, the dust screen 4 effectively blocks dust, maintains the cleanliness of the electrode chamber 1, improves the dust removal efficiency and the service life of the equipment.

[0037] It should be noted that the cathode 102 described in the text is also a discharge electrode, and the model of the heating sheet 202 is SUS100.

[0038] Finally, it should be noted that the above only describes the preferred embodiments of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacements to some technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
