Description

Technical Field

[0001] This invention relates to the field of electrostatic precipitator technology, specifically to a dry circulating electrostatic precipitator. Background Technology

[0002] Electrostatic precipitator technology utilizes the electrostatic force generated by a high-voltage electric field to charge dust particles in flue gas. Under the influence of the electric field, the charged dust particles are separated from the airflow, moving towards the anode and cathode and adhering to the electrode surfaces, thus achieving gas-solid separation and dust removal. Dry electrostatic precipitators, with their advantages of handling large volumes of flue gas, low operating resistance, and simple maintenance, have been widely used in flue gas control in coal-fired power plants, metallurgy, cement, chemical and other industrial fields.

[0003] CN114589009A describes a dry circulating electrostatic precipitator that uses a conductive frame to energize a conductive strip and an electrostatic sheet, while limiting the energization. This allows for dust collection on the electrostatic sheet and the conductive frame. When the electrostatic sheet moves to its lowest point and aligns with the collection hood, the collected dust is then collected by a high-speed airflow. This design also allows for the surface to be tapped on the dust-collecting electrostatic sheet, thus solving the problem of secondary pollution.

[0004] To address the issues in existing technologies, such as uneven distribution of circulating ash, blockage of pipes, inability to pick up fine ash, easy escape, re-entrainment of ash during rapping cleaning (secondary dust generation), "back corona" on the plates when encountering high resistivity dust, drastic efficiency drop, easy clogging of the ash hopper, and uneven return of circulating ash. Summary of the Invention

[0005] The technical solution provided by this invention is as follows: A dry circulating electrostatic precipitator, comprising:

[0006] The treatment enclosure features a horizontally penetrating ventilation structure. A tapered exhaust pipe is located at the bottom of the enclosure. An adsorption device is fixedly connected to the inner wall of the enclosure. A dust collection device is connected to the bottom of the enclosure. A fixed base is fixedly connected to the side of the enclosure. The enclosure also includes air vents for converging and diffusing air, located on both sides of the enclosure. The dust collection device includes a dust collection pipe for collecting dust and releasing air. A fixed end of a motor is fixedly connected to the inner wall of the dust collection pipe. A conveying pipe is fixedly connected to the motor's drive shaft. The drive end of a gear assembly is fixedly connected to the top of the conveying pipe. A mixing assembly is fixedly connected to the output end of the gear assembly. The components include a conveying pipe with a pressing plate fitted and fixedly connected to its side, a filter ring fitted and rotatably connected to the side of the pressing plate, a filter ring fixedly connected to the side of the inner wall of the processing housing, and a rotating bracket providing rotational support for the conveying pipe. The side of the rotating bracket is fixedly connected to the side of the inner wall of the dust collection pipe. During operation, air enters the air duct through the external conveying equipment and then passes through the inside of the processing housing for electrostatic dust removal. Dust is adsorbed on the side of the adsorption device and cleaned by the scraping mechanism set in the adsorption device. The dust falls under the action of the dust collection device. The fixed base supports the processing housing. After the motor is started, the motor drive shaft drives... The conveying pipe rotates, and the motor is fixed at the lower end of the dust collection pipe. The conveying pipe is vertically inserted inside the dust collection pipe. The rotating support is a bearing seat fixed to the inner wall of the dust collection pipe. During the rotation of the conveying pipe, the dust rotates inside the dust collection pipe due to the rotational support of the rotating support. The dust falls and passes through the inside of the filter ring under the action of the rotating extrusion plate. The extrusion plate is fixed to the outer wall of the conveying pipe and located above the filter ring. The filter ring is fixed to the inner wall of the dust collection pipe. The dust accumulates at the top of the filter ring and is squeezed and crushed by the extrusion plate before falling. After falling into the inside of the conveying pipe, the dust enters the mixing component through the rising airflow inside the conveying pipe. An air inlet is provided at one end. Air enters through the air inlet as the conveying pipe rotates, forming an upward airflow. This upward airflow is then driven by a reversing structure inside the gear assembly to rotate the mixing component laterally. The gear assembly consists of a driving bevel gear fixed to the outer wall of the conveying pipe and a driven bevel gear fixed to the rotating shaft of the mixing component. The crushed dust is sprayed into the introduced air, allowing the dust to combine with the unevenly distributed dust particles in the air, which facilitates the enhancement of the electrostatic dust removal effect. The circulating dust mixes with the fine dust in the flue gas. The fine dust adheres to the circulating dust, forming larger dust clumps. These larger dust clumps are more easily attracted by electrostatics and are less likely to escape.

[0007] Preferably, the rotating pipe for releasing air and the ejector pipe offset from the rotation center of the rotating pipe are provided. The ejector pipe has an air inlet groove on its side and a mixing groove on its inner wall side. The air inlet pipe is configured as a horizontal rotating mechanism. The side of the air inlet pipe is fixedly connected to the side of the rotating pipe and the side of the air inlet pipe is fixedly connected to the output end of the gear assembly. The side of the air inlet pipe is connected to the side of the conveying pipe. When working, the dust-laden air in the conveying pipe enters the air inlet pipe and flows along the rotating pipe, driving the ejector pipe to rotate. The ejector pipe offsets from the rotation center of the rotating pipe, causing the air to be ejected from the air inlet groove under centrifugal force and mixed with the air in the mixing groove.

[0008] Preferably, the conveying pipe includes an air supply pipe, with an inlet pipe fixedly connected to the bottom of the air supply pipe and a drive fan fixedly connected to the inner wall side of the inlet pipe. When the drive fan rotates with the inlet pipe, it pushes the dust-laden air upward into the air supply pipe, reducing dust accumulation in the conveying pipe.

[0009] Preferably, the extrusion plate includes an air guide cone, a connecting plate is fixedly connected to the bottom of the air guide cone, and an arc-shaped blade is fixedly connected to the bottom of the connecting plate. When the air guide cone rotates synchronously with the conveying pipe, it disperses the airflow to all sides. The connecting plate drives the arc-shaped blade to rotate and extrudes and scrapes the dust on the top of the filter ring, making it easier for the dust to enter the dust collection pipe downwards.

[0010] Preferably, the air guide cone is sleeved on the side of the air supply pipe and fixedly connected to the side of the air supply pipe. The arc-shaped blade is set as a downwardly guiding arc-shaped structure. The arc-shaped blade is set inside the filter ring. When the air supply pipe rotates, the air guide cone rotates synchronously with the air supply pipe. The downwardly guiding arc-shaped blade pushes the dust downward. The arc-shaped structure reduces the axial thrust on the dust during the scraping process, allowing the dust to pass through the filter ring more smoothly and fall into the dust collection pipe.

[0011] Preferably, the filter ring includes a rotating ring, a crushing ring fixedly connected to the bottom of the rotating ring, a squeezing hole opened at the top of the crushing ring, a fixing ring fixedly connected to the top of the squeezing hole, a side of the fixing ring fixedly connected to the side of the inner wall of the processing shell, a rotating ring rotatably connected to the bottom of the air guide cone, and an arc-shaped blade extending into the interior of the crushing ring. The rotation of the air supply pipe drives the air guide cone to rotate, the air guide cone is fixed to the outer wall of the air supply pipe, and the rotation of the air guide cone drives the connecting plate to rotate. One end of the connecting plate is fixed to the air guide cone, and the other end is fixed to the arc-shaped blade. The rotation of the connecting plate drives the arc-shaped blade to rotate, and the rotation of the arc-shaped blade causes some air to flow downward and carries the scraped dust into the interior of the dust collection pipe. The downward-sloping arc design of the blades gradually changes the dust-scraping process from line-based to point-based, thereby reducing resistance during dust handling. The connecting plate supports the arc-shaped blades, which rotate inside the crushing ring. The crushing ring is fitted around the arc-shaped blades. The arc-shaped structure of the crushing ring reduces the possibility of dust overflow after entering the crushing ring. The rotating ring is fitted at the bottom of the air guide cone and forms a rotational fit with the inner wall of the crushing ring. The fixing ring is fixed to the inner wall of the processing shell to secure the crushing ring. The extrusion holes are opened on the circumferential wall of the crushing ring. The extrusion holes crush large dust particles into smaller dust particles, reducing the bridging effect of dust accumulation.

[0012] Preferably, the adsorption device includes an adsorption plate, with the fixed end of a lifting rod fixedly connected to the side of the adsorption plate, and a scraper fixedly connected to the movable end of the lifting rod. The side of the adsorption plate is connected with charges of different polarities. The scraper is nested on the top of the adsorption plate and slidably connected to the adsorption plate. After the adsorption plate is connected with charges of different polarities, it electrostatically adsorbs dust in the air. The lifting rod drives the scraper to move up and down and scrapes the dust accumulated on the adsorption plate. The adsorption plate is arranged in multiple layers horizontally to increase the contact area between the dust and the adsorption plate.

[0013] Preferably, the scraper includes a scraping plate with a scraping hole at its top. A movable base is fixedly connected to the side of the scraping plate, and the scraping plate is set at a certain angle. The scraping hole is sleeved on the side of the adsorption plate and slidably connected to the adsorption plate. A certain gap is provided between the scraping hole and the side of the adsorption plate. The movable base is fixedly connected to the lifting rod drive unit. The multiple adsorption plates are multiple vertically parallel metal plates. Adjacent adsorption plates are respectively connected to a high-voltage power supply and ground. By connecting multiple adsorption plates with different polarity charges, dust in the air is electrostatically adsorbed. The lifting rod is a screw structure. The lifting rod drives the scraper to move up and down to scrape the dust accumulated on the adsorption plates. The adsorption plates are horizontally multi-layered. The design facilitates the electrostatic adsorption of dust from the air. The lifting rod moves the movable base, which is fixed to the lifting rod. The movable base causes the scraper to descend and slide against the side of the adsorption plate. The inclined design of the scraper reduces the resistance during the overall movement of the scraper and concentrates the stress at the connection between the scraper and the movable base. Scraping holes are made on the scraper, which are fitted onto the side of the adsorption plate with a certain gap. The gap between the scraping hole and the side of the adsorption plate is maintained in the range of 0.5 mm to 2 mm. After scraping, a thin layer of dust is left. The dust forms a thin layer on the side of the adsorption plate, making it easier to scrape off newly adsorbed dust and less likely to stick.

[0014] The beneficial effects of the technical solution provided by this invention include:

[0015] 1. After air enters the processing housing through the air duct, it first undergoes electrostatic adsorption. Dust is retained by the side of the adsorption device. The scraper scrapes down the accumulated dust and makes it fall downwards. The processing housing is supported by the bottom. After the motor starts, the conveying pipe begins to rotate. Air enters from the lower end of the conveying pipe. The rising airflow generated during rotation carries the falling dust into the mixing component. After the dust falls to the top of the filter ring, it is repeatedly crushed and pulverized. The pulverized dust is sprayed into the introduced air. The circulating dust and the fine dust in the flue gas stick together to form larger dust clumps. The larger dust clumps are more easily attracted by electrostatics and are not easily carried away by the airflow.

[0016] 2. After the motor drives the inlet pipe to rotate, it drives the fan to force the dust-laden air into the air supply pipe. The dust-laden air enters the air inlet pipe upward along the air supply pipe, and is then thrown out by the rotating pipe. The throwing pipe rotates in the mixing tank, and the air passes over the side of the air inlet slot. When the external air enters the mixing tank, it carries out the thrown-out dust-laden air and mixes with it. The dust and the freshly treated ash particles collide and combine with each other, and the fine ash is more likely to be wrapped into larger particles, which are more likely to be retained during the subsequent electrostatic adsorption.

[0017] 3. When the air supply pipe rotates, the air guide cone rotates as well. The arc-shaped blades press some of the air downwards, and the scraped dust is carried into the dust collection pipe. After the blades are tilted downwards, the resistance to scraping dust will be smaller. After the dust enters the crushing ring, it will not easily come out. Larger dust clumps are crushed into small particles when passing through the extrusion hole. When they accumulate, they are not easy to bridge, and the dust is not easy to get stuck.

[0018] 4. The adsorption plate consists of multiple vertically arranged metal plates. Adjacent plates are connected to high voltage and ground respectively. When the plate surface is electrified, it can attract dust in the air. The lifting rod drives the scraper to move up and down. The holes on the scraper slide around the adsorption plate. A very narrow gap is left between the scraping hole and the plate surface. After scraping, a thin layer of dust will remain on the plate surface. Newly fallen dust adheres to this thin layer of dust, making it easier to remove during cleaning and less likely to stick. Attached Figure Description

Detailed Implementation

[0028] Example 1, please refer to Figures 1-2 This invention provides a technical solution: a dry circulating electrostatic precipitator. Air enters the interior of the air duct 3 through an external conveying device and then passes through the interior of the processing shell 2 for electrostatic dust removal. Dust is adsorbed on the side of the adsorption device 4 and cleaned by the scraping mechanism set in the adsorption device 4. The dust falls under the action of the dust collection device 6. The fixed base 1 supports the processing shell 2. The motor 602 is started, and the drive shaft of the motor 602 drives the conveying pipe 604 to rotate. The motor 602 is fixed at the lower end of the dust collection pipe 601. The conveying pipe 604 is vertically inserted into the dust collection pipe 601. The rotating bracket 603 is a bearing seat fixed to the inner wall of the dust collection pipe 601. During the rotation of the conveying pipe 604, it is supported by the rotation of the rotating bracket 603 and rotates inside the dust collection pipe 601. The dust falls under the action of the rotation of the extrusion plate 605 and passes through the interior of the filter ring 606. The extrusion plate 605 is fixed to the outer wall of the conveying pipe 604 and located at the filter ring 606. Above, the filter ring 606 is fixed to the inner wall of the dust collection pipe 601. Dust accumulates on the top of the filter ring 606 and is squeezed and crushed by the extrusion plate 605 and falls down. After falling into the interior of the conveying pipe 604, the dust enters the interior of the mixing component 608 through the rising airflow inside the conveying pipe 604. The lower end of the conveying pipe 604 has an air inlet. When the conveying pipe 604 rotates, air enters through the air inlet to form an rising airflow. This airflow is driven to rotate laterally by the reversing structure inside the gear assembly 607. The gear assembly 607 is formed by the meshing of the driving bevel gear fixed to the outer wall of the conveying pipe 604 and the driven bevel gear fixed to the rotating shaft of the mixing component 608. The crushed dust is sprayed into the introduced air, so that the dust combines with the uneven dust particles in the air, which facilitates the increase of electrostatic dust removal effect. The circulating dust and the fine dust in the flue gas are mixed together. The fine dust will stick to the circulating dust and become larger dust clumps. The larger dust clumps are more easily attracted by electrostatics and are not easy to escape.

[0029] Example 2, please refer to Figures 1-4 Based on the first embodiment, the drive shaft of motor 602 rotates, causing the inlet pipe 6042 to rotate. A drive fan 6043 is fixed to the upper end of the inlet pipe 6042. The inlet pipe 6042 is inserted into the lower end of the air supply pipe 6041. The rotation of the inlet pipe 6042 drives the drive fan 6043 to rotate, which in turn drives dust-laden air into the air supply pipe 6041 and upwards into the air intake pipe 6082. The air supply pipe 6041 and the air intake pipe 6082 are connected by a gear assembly 607. One gear of the gear assembly 607 is fixed to the upper end of the air supply pipe 6041, and the other gear is fixed to the lower end of the air intake pipe 6082. The two gears mesh with each other, changing the vertical rotation to a horizontal rotation. Dust-laden air enters the rotating pipe 6081 and is then transported upwards into the air intake pipe 6082. Driven by the air pipe 6082, the ejector pipe 6083 rotates. The rotating pipe 6081 is fixedly connected to the air inlet pipe 6082. The ejector pipe 6083 is fixed to the side wall of the rotating pipe 6081 and extends radially. The rotation of the ejector pipe 6083 causes air to be ejected. During the air purification process, the ejector pipe 6083 slides along the side of the air inlet slot 6084 and passes through the interior of the mixing tank 6085. The mixing tank 6085 is an annular cavity fixed inside the processing housing 2. The air inlet slot 6084 is opened on the side wall of the mixing tank 6085. The ejector pipe 6083 extends into the mixing tank 6085 and combines the dust-laden air with the outside air, thereby facilitating the combination of impurities in the air and the processed dust. The combination of the mixing tank 6085 and the air inlet slot 6084 facilitates the discharge of the dust-laden air inside the ejector pipe 6083 during the flow of outside air.

[0030] Example 3, please refer to Figures 1-6Based on the second embodiment, the rotation of the air supply pipe 6041 guides the rotation of the air guide cone 6051. The air guide cone 6051 is fixed to the outer wall of the air supply pipe 6041. The rotation of the air guide cone 6051 drives the rotation of the connecting plate 6052. One end of the connecting plate 6052 is fixed to the air guide cone 6051, and the other end is fixed to the arc-shaped blade 6053. The rotation of the connecting plate 6052 drives the arc-shaped blade 6053 to rotate. The rotation of the arc-shaped blade 6053 causes some air to flow downward and carries the scraped dust into the interior of the dust collection pipe 601. The downward-sloping arc-shaped setting of the arc-shaped blade 6053 changes the dust scraping process from line connection to point connection, thereby reducing the resistance during dust handling. The setting of the connecting plate 6052... The arc-shaped blade 6053 provides support and rotates inside the crushing ring 6062. The crushing ring 6062 is fitted around the arc-shaped blade 6053. The arc-shaped structure of the crushing ring 6062 allows dust to enter the interior of the crushing ring 6062, reducing the possibility of dust overflow. The rotating ring 6061 is fitted around the bottom of the air guide cone 6051 and forms a rotational engagement with the inner wall of the crushing ring 6062. The fixing ring 6064 is fixed to the inner wall of the processing housing 2 to fix the crushing ring 6062. The extrusion hole 6063 is opened on the circumferential wall of the crushing ring 6062. The extrusion hole 6063 crushes large dust particles into smaller dust particles, reducing the bridging effect of dust accumulation.

[0031] Example 4, please refer to Figures 1-8 Based on the third embodiment, the adsorption plate 401 consists of multiple vertically parallel metal plates. Adjacent adsorption plates 401 are connected to a high-voltage power supply and ground, respectively. By connecting different polarities of charges to the adsorption plates 401, dust in the air is electrostatically adsorbed. The lifting rod 402 is a lead screw structure. The lifting rod 402 drives the scraper 403 to move up and down to scrape the dust accumulated on the adsorption plates 401. The horizontal multi-layer arrangement of the adsorption plates 401 facilitates the electrostatic adsorption of dust in the air. The lifting rod 402 drives the moving base 4033 to move. The moving base 4033 is fixed on the lifting rod 402. The moving base 4033 carries... The moving scraper plate 4031 descends and slides against the side of the adsorption plate 401. The inclined setting of the scraper plate 4031 reduces the resistance when the scraper plate 4031 moves as a whole, and concentrates the stress at the connection between the scraper plate 4031 and the moving base 4033. The scraper plate 4031 has a scraping hole 4032, which is fitted onto the side of the adsorption plate 401 with a certain gap. The gap between the scraping hole 4032 and the side of the adsorption plate 401 is maintained within a certain range. After scraping, a thin layer of dust is left. The dust forms a thin layer of dust on the side of the adsorption plate 401, and the newly adsorbed dust is easier to scrape off and is not easy to stick.
