Description

Technical Field

[0001] The present invention relates to the technical field of electrostatic dust removal heating, and particularly to a heating coordination mechanism for efficient dust removal. Background Art

[0002] Electrostatic dust removal is a method of gas dust removal; when the dusty gas passes through a high-voltage electrostatic field, it is electrically separated. After the dust particles combine with negative ions and carry negative charges, they tend to discharge on the anode surface and deposit; it is used in industries such as metallurgy and chemistry to purify gases or recover useful dust particles; a dust collection method that uses an electrostatic field to ionize gas so that dust particles are charged and adsorbed onto the electrodes; in a strong electric field, air molecules are ionized into positive ions and electrons. When the electrons run towards the positive electrode, they encounter dust particles, making the dust particles carry negative charges and be adsorbed onto the positive electrode and collected; of course, through technological innovation, there is also a method of collecting dust using a negative electrode plate; it was formerly commonly used in factories and power stations fueled by coal to collect coal ash and dust in flue gas; in metallurgy, it is used to collect oxides of tin, zinc, lead, aluminum, etc., and there are also dust removal and sterilization products that can be used in homes.

[0003] Before performing electrostatic dust removal on the gas in a thermal power plant, it is necessary to heat the gas in the pipeline to remove the moisture in the gas. Since the gas contains acidic substances, the wet gas adhering to the inside of the device easily causes corrosion of the device. Moreover, the traditional porcelain sleeve heating device has a small contact area with the gas during heating, and the too-fast gas flow rate will result in insufficient gas heating effect, causing moisture to exist in the gas flow and reducing the subsequent dust removal effect.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

At the inner center of the flue gas flow channel, an electric heater is fixedly installed through multiple fixed shafts. An annular porcelain sleeve is fixedly sleeved outside the electric heater. A first temperature detector and a second temperature detector are respectively fixedly installed at both ends of the annular porcelain sleeve on the outer side wall of the electric heater. A sliding ring is arranged between every two adjacent annular porcelain sleeves.

One end of the rectangular base away from the sliding ring is fixedly installed with a driving blade. A cleaning collar is movably sleeved on the outer side wall of the driving blade. A limiting groove is formed on the surface of the driving blade. A dust removal box is also installed at one end of the driving blade away from the rectangular base. A gear belt is movably sleeved in the cleaning slider through multiple rotating shafts. A first transmission connecting rod is rotatably connected inside the cleaning slider. A first transmission bevel gear and a first transmission gear are fixedly installed on the outer side wall of the first transmission connecting rod. A second transmission connecting rod is also rotatably connected inside the cleaning slider. A second transmission bevel gear and a third transmission gear are respectively fixedly installed at both ends of the second transmission connecting rod. A driving toothed ring is movably and limit-sleeved inside the cleaning slider and the rectangular base. A second limiting connecting rod is fixedly installed at the bottom of the driving toothed ring. The second limiting connecting rod is limit-movably sleeved inside the cleaning slider. A first limiting connecting rod is fixedly installed at the top of the driving toothed ring. The first limiting connecting rod is movably and limit-sleeved inside the rectangular base and the driving blade. And the outer side wall of the first limiting connecting rod is fixedly connected with the cleaning collar through the limiting groove.

[0007] Preferably, balls are arranged at the part of the inner side wall of the sliding ring in contact with the annular porcelain sleeve, and an arc-shaped groove adapted to the annular protrusion on the surface of the annular porcelain sleeve is arranged on the side surface of the cleaning slider.

[0008] Preferably, the driving blades arranged on the outer sides of two adjacent sliding rings are perpendicular to each other in the radial direction of the electric heater.

[0009] Preferably, along the direction of air flow, the length of the driving blade gradually becomes longer.

[0010] Preferably, the first transmission gear meshes with the tooth group on the outer side wall of the gear belt, the first transmission bevel gear meshes with the second transmission bevel gear, two symmetric rack groups are arranged on the inner side wall of the driving toothed ring, and the third transmission gear meshes with the rack group inside the driving toothed ring.

[0011] Preferably, the part of the outer side wall of the third transmission gear provided with the tooth group is less than half of the length of the outer side wall area of the third transmission gear.

[0012] Preferably, the rack group of the gear belt extends to the outside of the cleaning slider, and a tooth pick adapted to the gear belt is fixedly installed on one side of the cleaning slider away from the gear belt.

[0013] Preferably, one side of the driving blade facing the direction of the air flow is designed in an arc shape. The cleaning collar fits on the surface of the driving blade. A dust collection port is formed on one side of the dust removal box facing the cleaning collar. A reset link is rotatably connected to the inner side of the dust removal box.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

This not only ensures the efficient progress of subsequent dust removal work but also avoids the corrosion of internal devices by the gas.

[0016] 2. When the air flow drives the sliding ring to rotate, it can scrape and clean the annular protrusions provided on the surface of the annular porcelain sleeve, preventing impurities from adhering and the corrosive gas moisture in the air flow from adhering to the surface of the annular porcelain sleeve after evaporation. At the same time, it can automatically clean the surface of the driving blades, ensuring the overall heat dissipation effect and anti-corrosion protection effect.

[0017] 3. Through the design of the dust removal box, it is possible to capture and collect large particulate impurities in the air flow and pre-treat dust impurities in the air flow, reducing the pressure of subsequent dust removal work and also reducing the impact of large particulate impurities on subsequent electrostatic dust removal work.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Reference Figure 1-8, A heating coordination mechanism for efficient dust removal, including a flue gas flow channel 1. At the inner center of the flue gas flow channel 1, an electric heater 2 is fixedly installed through multiple groups of fixed shafts. An annular porcelain sleeve 23 is fixedly sleeved outside the electric heater 2. A first temperature detector 21 and a second temperature detector 22 are respectively fixedly installed at both ends of the annular porcelain sleeve 23 on the outer side wall of the electric heater 2. A sliding ring 3 is arranged between every two adjacent annular porcelain sleeves 23. Multiple cleaning sliders 31 evenly distributed along the ring are fixedly installed on the outer side wall of the sliding ring 3. One end of the cleaning slider 31 away from the sliding ring 3 is fixedly installed with a rectangular base 32. One end of the rectangular base 32 away from the sliding ring 3 is fixedly installed with a driving blade 4. A cleaning collar 41 is movably sleeved on the outer side wall of the driving blade 4. A limiting groove 42 is formed on the surface of the driving blade 4. A dust removal box 5 is further installed at one end of the driving blade 4 away from the rectangular base 32. Inside the cleaning slider 31, a gear belt 312 is limited and movably sleeved through multiple groups of rotating shafts. A first transmission connecting rod 311 is rotatably connected inside the cleaning slider 31. A first transmission bevel gear 313 and a first transmission gear 314 are fixedly installed on the outer side wall of the first transmission connecting rod 311. A second transmission connecting rod 315 is also rotatably connected inside the cleaning slider 31. A second transmission bevel gear 316 and a third transmission gear 318 are respectively fixedly installed at both ends of the second transmission connecting rod 315. A driving gear ring 44 is movably limited and sleeved inside the cleaning slider 31 and the rectangular base 32. A second limiting connecting rod 45 is fixedly installed at the bottom of the driving gear ring 44. The second limiting connecting rod 45 is limited and movably sleeved inside the cleaning slider 31. A first limiting connecting rod 43 is fixedly installed at the top of the driving gear ring 44. The first limiting connecting rod 43 is movably limited and sleeved inside the rectangular base 32 and the driving blade 4. And the outer side wall of the first limiting connecting rod 43 is fixedly connected with the cleaning collar 41 through the limiting groove 42;

[0029] Specifically, the heating section of the electric heater 2 is wrapped by the annular porcelain sleeve 23. The first temperature detector 21 and the second temperature detector 22 are arranged at both ends of the annular porcelain sleeve 23, which can avoid the influence of the heating of the electric heater 2, can measure the temperature of the air flow before and after passing through the whole device in real time, and can analyze the data in real time through the central control room to master and adjust the heating parameters. This is the prior art and will not be elaborated here, so as to improve the dust removal efficiency;

[0030] The sliding ring 3, the driving blade 4 and their connection components in contact with the air flow are all made of aluminum alloy, which has the advantages of good heat dissipation effect, light weight and corrosion resistance, and can ensure the stable operation of the device;

[0031] When the component connected to the sliding ring 3 rotates through the sliding ring 3, the heat on the surface of the annular porcelain sleeve 23 can be dissipated through the rotation of the sliding ring 3 and the driving blades 4, increasing the contact area between the heating device and the air flow, making the heating efficiency of the electric heater 2 for the air flow higher, ensuring the efficient removal of moisture in the air flow, preventing subsequent condensation corrosion of the device, and also ensuring the high efficiency of electrostatic dust removal.

[0032] As Figure 3 , balls are provided at the part where the inner side wall of the sliding ring 3 contacts the annular porcelain sleeve 23, and an arc-shaped groove adapted to the annular protrusion on the surface of the annular porcelain sleeve 23 is provided on the side surface of the cleaning slider 31;

[0033] Specifically, the balls can greatly reduce the friction between the sliding ring 3 and the annular porcelain sleeve 23 while ensuring the heat transfer effect, ensuring the rotation of the sliding ring 3. At the same time, the arc-shaped groove can scrape and clean the annular protrusion provided on the surface of the annular porcelain sleeve 23 as the cleaning slider 31 rotates, preventing impurities from adhering and the corrosive gas moisture in the air flow from adhering to the surface of the annular porcelain sleeve 23 after evaporation. While ensuring the heat transfer effect of the annular porcelain sleeve 23, it avoids corrosion of the annular porcelain sleeve 23 and ensures the stable operation of the overall work.

[0034] As Figure 1 , the driving blades 4 provided on the outer sides of two adjacent groups of sliding rings 3 are perpendicular to each other along the radial direction of the electric heater 2;

[0035] Specifically, when the air flow blows on the driving blades 4, the rotation directions of the adjacent driving blades 4 are opposite, avoiding the relative rotation speed of the adjacent groups of sliding rings 3 being too slow to cause the device to malfunction, and it can also make the contact frequency of the adjacent groups of cleaning sliders 31 higher, improving the cleaning efficiency of the surface of the driving blades 4.

[0036] As Figure 1 , along the air flow direction, the length of the driving blades 4 gradually increases;

[0037] Specifically, through the design of gradually increasing the length of the driving blades 4, when the driving blades 4 contact the air flow, the flow rate of the air flow can be gradually and evenly reduced, ensuring the heat transfer and dissipation of the heat on the surface of the annular porcelain sleeve 23 by the driving blades 4, significantly increasing the contact area between the heating device and the air flow, making the heating efficiency of the electric heater 2 for the air flow higher, and ensuring the efficient removal of moisture in the air flow.

[0038] As Figure 5 , the first transmission gear 314 meshes with the tooth group on the outer side wall of the gear belt 312, the first transmission bevel gear 313 meshes with the second transmission bevel gear 316, two symmetrically arranged rack groups are provided on the inner side wall of the driving tooth ring 44, and the third transmission gear 318 meshes with the rack group inside the driving tooth ring 44.

[0039] As Figure 7 , the portion of the outer wall of the third transmission gear 318 where the tooth group is provided is less than half of the length of the outer wall area of the third transmission gear 318;

[0040] Specifically, through the local tooth group design of the third transmission gear 318, every time the third transmission gear 318 rotates one circle, the driving tooth ring 44 can be driven to complete a set of linear reciprocating cyclic motions in the direction perpendicular to the axis line of the electric heater 2 through the cooperation of the third transmission gear 318 and the inner tooth group of the driving tooth ring 44.

[0041] As Figure 6 , the rack group of the gear belt 312 extends to the outside of the cleaning slider 31, and a pick-off tooth 317 adapted to the gear belt 312 is fixedly installed on the side of the cleaning slider 31 away from the gear belt 312;

[0042] Specifically, the pick-off teeth 317 of each group of cleaning sliders 31 are all close to the side wall of the adjacent group of cleaning sliders 31 and remain engaged with the gear belt 312. Every time the pick-off teeth 317 pass by the gear belt 312, the gear belt 312 can be driven to rotate.

[0043] As Figure 8 , one side of the driving blade 4 facing the direction of the air flow is designed in an arc shape. The cleaning collar 41 is attached to the surface of the driving blade 4. A dust collection port 51 is opened on one side of the dust collection box 5 facing the cleaning collar 41. A reset link 52 is rotatably connected to the inside of the dust collection box 5. A torsion spring 54 is also provided at the connection part of the reset link 52 and the inner side wall of the dust collection box 5. A dust collection baffle 53 adapted to the dust collection port 51 is fixedly installed on the outer side wall of the reset link 52. A plurality of groups of staggered filter groups 55 are fixedly installed inside the dust collection box 5. A plurality of groups of evenly distributed communication mesh grooves 56 are also provided at one end of the dust collection box 5 away from the cleaning collar 41;

[0044] Specifically, the filter groups 55 all extend to half of the height of the inner side wall of the dust collection box 5. Through the staggered design, large particulate impurities in the air flow can enter along the inclined surface of the filter groups 55. When the driving blade 4 rotates to drive the dust collection box 5 to be at the highest position, the large particulate impurities inside the dust collection box 5 are blocked by the inclined surface of the filter groups 55 when falling under the action of gravity and are deposited at the angle between the filter groups 55 and the inner side wall of the dust collection box 5, realizing the capture and collection of large particulate impurities in the air flow and the pretreatment of dust impurities in the air flow, reducing the pressure of subsequent dust removal work.

[0045] The torsion provided by the torsion spring 54 drives the dust collection baffle 53 to block the dust collection port 51 when the device is stationary and not working, preventing the collected dust from flowing out of the dust collection port 51. At the same time, the dust collection box 5 and the driving blade 4 are designed in a detachable installation manner, and the dust collection box 5 can be directly removed for cleaning when cleaning the inside of the dust collection box 5.

[0046] In the present invention, during operation, the airflow to be dust-removed flows inside the flue gas flow channel 1 through the electric heater 2 and the annular porcelain sleeve 23. When the airflow passes through the driving blades 4, due to the relatively high flow rate of the airflow, it can push the inclined surface of the blades 4, and then drive the driving blades 4 and the sliding ring 3 to slowly rotate along the outer side wall of the annular porcelain sleeve 23. At the same time, the flow rate of the airflow decreases. The rotation of the sliding ring 3 and the driving blades 4 can dissipate the heat generated by the annular porcelain sleeve 23, greatly increasing the contact area between the heating mechanism and the airflow, significantly increasing the contact area between the heating device and the airflow, making the heating efficiency of the electric heater 2 for the airflow higher, and enabling the efficient removal of moisture in the airflow. At the same time, the arc-shaped groove on the side surface of the cleaning slider 31 can scrape and clean the annular protrusions provided on the surface of the annular porcelain sleeve 23 as the cleaning slider 31 rotates, preventing impurities from adhering and the corrosive gas moisture in the airflow from adhering to the surface of the annular porcelain sleeve 23 after evaporation, while ensuring the heat transfer effect of the annular porcelain sleeve 23 and avoiding corrosion of the annular porcelain sleeve 23;

[0047] Because under the blowing of the airflow, the rotation directions of adjacent driving blades 4 are opposite, avoiding the relative rotation speed of adjacent groups of sliding rings 3 being too slow to cause the device to malfunction, and enabling the contact frequency of adjacent groups of cleaning sliders 31 to be higher. The rotation of the sliding ring 3 drives the cleaning slider 31 to rotate. When the teeth 317 on the side surfaces of adjacent two groups of cleaning sliders 31 pass through the gear belt 312, they can drive the gear belt 312 to rotate, and then drive the first transmission gear 314 and the first transmission connecting rod 311 to rotate, and then drive the first transmission bevel gear 313 to rotate. The first transmission bevel gear 313 drives the second transmission bevel gear 316 to rotate, and then drives the second transmission connecting rod 315 to rotate, thereby driving the third transmission gear 318 to rotate. Through the tooth group partially provided on the outer side wall of the third transmission gear 318, every time the third transmission gear 318 rotates one circle, it can drive the driving ring gear 44 to complete a set of linear reciprocating cyclic motions in the direction perpendicular to the axis line of the electric heater 2 through the cooperation of the third transmission gear 318 and the internal tooth group of the driving ring gear 44. At the same time, the movement of the driving ring gear 44 drives the first limiting connecting rod 43 to move inside the driving blade 4 and the rectangular base 32, and then drives the cleaning collar 41 to move in a cycle on the surface of the driving blade 4, scraping and cleaning the solidified impurities adhering and deposited on the surface of the driving blade 4, ensuring the heat dissipation effect of the driving blade 4. At the same time, since the adjacent driving blades 4 along the axis line of the electric heater 2 are perpendicular to each other, the cleaning efficiency of the surface of the driving blade 4 is improved;

[0048] Meanwhile, the arc design on the surface of the driving blade 4 can increase the contact area with the air flow, making the heat conduction and heating effects of the driving blade 4 better. When the driving blade 4 rotates, the air flow blows in the direction of the dust collection port 51 along the arc design on the surface of the driving blade 4. By blowing the dust collection baffle 53, the reset link 52 is driven to rotate, and the air flow enters the interior of the dust removal box 5, passes through the filter screen group 55 in sequence and is discharged through the communication mesh groove 56. Through the staggered design of the filter screen group 55, large particle impurities in the air flow can enter along the inclined surface of the filter screen group 55. When the driving blade 4 rotates to drive the dust removal box 5 to the highest position, the large particle impurities inside the dust removal box 5 are blocked by the inclined surface of the filter screen group 55 when falling under the action of gravity, and are deposited at the angle between the filter screen group 55 and the inner side wall of the dust removal box 5, realizing the capture and collection of large particle impurities in the air flow and the pretreatment of dust impurities in the air flow, reducing the pressure of subsequent dust removal work.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
