Description

Technical Field

[0001] The present application relates to the technical field of air purification, and in particular to an electrostatic dust removal and automatic cleaning device thereof. Background Art

[0002] Electrostatic dust removal equipment is a common air purification equipment, widely used in industrial production, environmental protection and public places. It uses the principle of electrostatic action to settle particulate matter in the air to achieve the purpose of purifying the air. Electrostatic dust removal equipment is mainly composed of high-voltage power supply, discharge electrode, dust collecting electrode and other parts. The working principle of electrostatic dust removal equipment is: use high-voltage electric field to ionize the flue gas, and the dust in the airflow is charged and separated from the airflow under the action of the electric field. The negative electrode is made of metal wires with different cross-sectional shapes, called the discharge electrode; the positive electrode is made of metal plates with different geometric shapes, called the dust collecting electrode. Under the action of the electric field force, the charged dust tends to the dust collecting electrode and deposits on it to achieve the purpose of dust collection.

[0003] Since the dust will remain on the electrode after the electrostatic dust removal is completed, it needs to be cleaned up when it is used next time. When cleaning, it is necessary to first turn off the electrostatic dust removal equipment, turn off the power and wait for cooling, remove the electrostatic dust removal net, and clean the substances adhering to the dust removal net with water or cleaning. After waiting for it to be clean, it will be installed in the dust removal equipment. In this process, the electrostatic dust removal equipment cannot be used, which will cause the dust removal work to stop. Therefore, an electrostatic dust removal and automatic cleaning device that can also remove dust during the cleaning process are needed. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of this application is to provide an electrostatic dust removal and automatic cleaning device to solve the above problems.

[0005] The above-mentioned purpose of the present application is achieved through the following technical solutions: an electrostatic dust removal and automatic cleaning device thereof, comprising an electrostatic dust removal device, the electrostatic dust removal device comprising a No. 1 dust removal box and a No. 2 dust removal box, the No. 1 dust removal box and the No. 2 dust removal box are both fixedly provided with a mounting frame for placing a high-voltage electric box, through holes are evenly opened on the mounting frame, and dust accumulation plates are arranged under a plurality of the through holes, connecting plates are rotatably arranged at both ends of the dust accumulation plate, and one end of the connecting plate away from the dust accumulation plate is fixedly connected to the mounting frame, and discharge electrodes are arranged on both sides of the dust accumulation plate. The discharge electrode is fixedly connected to the mounting frame, the upper end of the No. 1 dust removal box is connected to a No. 1 gas pipeline, the end of the No. 1 gas pipeline away from the No. 1 dust removal box is connected to the No. 2 dust removal box, a No. 1 switch valve is installed on the No. 1 gas pipeline, the upper end of the No. 2 dust removal box is connected to a No. 2 gas pipeline (14), the end of the No. 2 gas pipeline away from the No. 2 dust removal box is connected to the No. 1 dust removal box, a pressurizing valve is installed in the No. 1 gas pipeline and the No. 2 gas pipeline, and the inlets of the No. 1 dust removal box and the No. 2 dust removal box are connected with a dust removal inlet pipeline.

[0006] By adopting the above technical scheme, when the dust removal inlet pipe enters the No. 1 dust removal box and the No. 2 dust removal box respectively, after the high-voltage electric box is discharged, the dust and dust in the exhaust gas are adsorbed by the electrode particles in the electrode, so that the dust is adsorbed by the dust accumulation plate. After adsorption for a period of time, the high-voltage electric box on the No. 1 dust removal box is closed first, and the No. 2 switch valve of the No. 2 gas pipeline is opened. A part of the air that has been dusted will enter the No. 1 dust removal box along the No. 2 gas pipeline. Since the high-voltage electric box on the No. 1 dust removal box has been closed, the dust accumulation plate will gradually lose its electromagnetic attraction, so that the dust adsorbed on it will no longer be firm. Therefore, the air will blow off the dust on the dust accumulation plate, and at the same time, the air will re-enter the No. 2 dust removal box along the inlet pipe to continue dust removal. After the No. 1 dust removal box is cleaned, the No. 2 dust removal box is also cleaned according to the above scheme.

[0007] Furthermore, the bottoms of the No. 1 dust removal box and the No. 2 dust removal box are both connected with recovery pipes, and the recovery pipes are connected with recovery boxes.

[0008] By adopting the above technical solution, the dust removed from the dust collecting plate will enter the collection box through the recovery pipe and be collected uniformly, which is convenient for subsequent processing or secondary utilization.

[0009] Furthermore, the dust collecting plate is provided with wind guide stripes, and the cross section of the wind guide stripes is curved.

[0010] By adopting the above technical solution, considering that simple pressurized air may not be able to clean and remove all the dust on the dust accumulation plate, the opening of the air guide stripes will cause the dust accumulation plate on the connecting plate to shake, thereby better removing the dust on the dust accumulation.

[0011] Furthermore, a linkage plate is provided at the bottom of the dust collection plate to connect the bottoms of multiple dust collection plates together.

[0012] By adopting the above technical solution, considering that the air enters only from one place, the dust collection plates on both sides receive less wind force, resulting in a lower shaking frequency. Therefore, after the dust collection plates are connected together through the linkage plates, the shaking dust collection plate in the middle will drive the dust collection plates on both sides, thereby driving all the dust collection plates to shake, thereby better cleaning the dust on the dust collection plates.

[0013] Furthermore, a linkage block is provided on one side of the linkage plate, a linkage rod is fixedly provided in the middle of the linkage block, a linkage motor is provided at one end of the linkage rod away from the linkage block, the linkage motor is fixedly provided in the electrostatic dust removal equipment, and the output end of the linkage motor is fixedly connected to the linkage rod.

[0014] By adopting the above technical solution, the linkage motor is started and driven, and the linkage rod will drive the linkage block to push the linkage plate, so that the linkage plate drives all the dust accumulation plates to swing, and the dust accumulation plates can be dusted more stably.

[0015] Furthermore, a water flushing device is provided at the other end of the dust removal inlet pipe, and the water flushing device includes a flushing pipe and a nozzle ring installed in the flushing pipe, and the nozzle ring is evenly distributed with spray heads. The nozzle ring is fixedly connected to a water pump, and the end of the water pump away from the spray head is connected to the filter container. One end of the flushing pipe is connected to the dust removal inlet pipe, and the other end is connected to the exhaust gas inlet pipe.

[0016] By adopting the above technical scheme, since large particles of dust may damage the dust accumulation plate during the electrostatic dust removal process and shorten its service life, the above scheme is set up to transmit the cleaning liquid in the filter container to the nozzle ring along with the water pump, and then reach the injection head, so as to pre-treat the air entering the electrostatic dust removal equipment, and separate the large particles of dust from the air along with the cleaning liquid, and then the air entering the electrostatic dust removal equipment will not contain large particles of dust.

[0017] Furthermore, the output ends of the injection heads are all tilted downward.

[0018] By adopting the above technical solution, the spray head is tilted downward to flush the middle part of the pipeline, and the cleaning liquid will be cross-sprayed to contact the particulate dust in the air more evenly, achieving a better pretreatment effect.

[0019] Furthermore, a rotating cylindrical body rotatably connected to the flushing pipe is provided in the flushing pipe, a rotating shaft is rotatably provided in the middle of the rotating cylindrical body, stirring plates are distributed in a circular array on the shaft body of the rotating shaft, the stirring plates are fixedly connected to the rotating shaft, a rotating motor is provided at the bottom of the rotating shaft, the rotating motor is fixedly connected to the flushing pipe, and the output end of the rotating motor is fixedly connected to the rotating shaft.

[0020] By adopting the above technical solution, the rotating motor drives the stirring plate on the rotating shaft. When the cleaning liquid and the air come into contact, they will be fully mixed by the stirring plate, so that the cleaning liquid and the air are mixed more fully.

[0021] Furthermore, a thread strip is provided on the inner side of the rotating cylindrical body, and the thread strip is evenly distributed in the rotating cylindrical body.

[0022] By adopting the above technical solution, when the stirring plate rotates, the air and the cleaning liquid are mixed. Due to the centrifugal force, the air is brought to the inside of the rotating cylindrical body, and the centrifugal force is brought to the threaded strips, so that the rotating cylindrical body rotates at the same time. The stirring plate and the rotating cylindrical body rotate at the same time, which will completely mix the particles in the air and the cleaning liquid, and fully react, so as to better perform pretreatment.

[0023] Furthermore, the bottom of the flushing pipe is in a cone shape, and drainage holes are provided around the flushing pipe.

[0024] By adopting the above technical solution, the treated cleaning liquid will flow to the bottom of the flushing pipe. Since the bottom is cone-shaped, it will flow into the hydrophobic holes and be separated.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. When the exhaust gas pipeline enters the No. 1 dust removal box and the No. 2 dust removal box respectively, after the high-voltage electric box is discharged, the dust and dust in the exhaust gas are adsorbed by the electrode particles in the electrode, and then the dust is adsorbed by the dust accumulation plate. After a period of adsorption, first close the high-voltage electric box on the No. 1 dust removal box, open the No. 2 switch valve of the No. 2 gas pipeline, and the dust-removed air will enter the No. 1 dust removal box through the No. 2 gas pipeline. Since the first stage closes the high-voltage electric box on the No. 1 dust removal box, the dust accumulation plate will gradually lose its electromagnetic attraction, and the dust adsorbed on it will no longer be firm, so The air will blow away the dust on the dust plate. Considering that the air that blows away the dust may be contaminated with a small amount of dust for the second time, the air will re-enter the No. 2 dust removal box through the inlet pipe to continue dust removal. After the No. 1 dust removal box is cleaned, the No. 2 dust removal box is also cleaned through the above scheme. The bottoms of the No. 1 and No. 2 dust removal boxes are connected with a recovery pipe, and the other end of the recovery pipe is connected to a recovery box. The dust removed from the dust plate will enter the collection box through the recovery pipe for unified collection, which is convenient for subsequent processing or secondary utilization.

The cleaning liquid in the filter container is transferred to the nozzle ring by the water pump, and then reaches the injection head to pre-treat the air entering the electrostatic dust removal equipment, and the large particles of dust in the air are separated from the air along with the cleaning liquid. The air entering the electrostatic dust removal equipment will not contain large particles of dust. The output ends of the injection heads are tilted downward to flush the middle of the pipe.
