Description

Technical Field

[0001] The present invention relates to the technical field of electrostatic precipitators, in particular to an electrostatic precipitator with a dust cleaning device. Background Art

[0002] Electrostatic precipitator is a kind of high-efficiency dust removal equipment that uses high-voltage electrostatic field to separate dust and gas. It is widely used in industrial fields such as electricity, metallurgy, and chemical industry. After the dust-laden gas enters the dust collector, it is ionized by the high-voltage electric field to produce a large number of electrons and ions. The dust particles absorb the charge and move to the opposite electrode under the action of the electric field force. They are eventually captured by the anode plate. The dust accumulated on the anode plate is then removed by the cleaning device and collected in the ash hopper, thereby achieving gas purification. When cleaning the anode plate, mechanical impact or vibration is used to remove the dust accumulated on the plate, which is a common cleaning method. There will be obvious attenuation when the force is transmitted through the electrode plate. The vibrating force is greater in the area close to the vibrating point, while the vibrating force is weaker at the edge or middle of the electrode plate away from the vibrating point, resulting in incomplete removal of dust accumulation. Long-term residual dust accumulation will reduce the conductivity of the anode plate, weaken the electric field strength, and thus reduce the dust removal efficiency. In addition, during the vibration, the dust accumulation on the electrode plate is shaken off. If the dust particles that fall off do not fall into the ash hopper in time, they may be re-rolled by the airflow flowing through the dust collector, forming "secondary dust", which will cause some dust to be discharged with the purified gas, reducing the actual dust removal effect, and even causing the outlet dust concentration to exceed the standard.

DETAILED DESCRIPTION

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0028] Example 1 Reference Figure 1 、 Figure 2 、 Figure 4 and Figure 7, which is the first embodiment of the present invention, and provides an electrostatic precipitator with a dust cleaning device. The electrostatic precipitator with a dust cleaning device includes a main assembly 100, including a box 101. The top of the box 101 is provided with an openable cover (not shown in the figure), and the bottom is provided with an ash hopper. An anode plate 102 is fixed in the box 101, and a discharge electrode 103 is provided on one side of the anode plate 102. There are multiple anode plates 102 and discharge electrodes 103. After the smoke enters the interior of the box 101, the discharge electrode 103 will generate an electric field and make the dust adhere to the anode plate 102, thereby removing the smoke. This is the existing technology, and this solution will not be elaborated in detail, and those skilled in the art can clearly understand the working principle.

[0029] The cleaning assembly 200 is arranged on one side of the anode plate 102 and includes a cleaning part 201. The cleaning part 201 includes a collecting frame 2011 located on one side of the anode plate 102. There are multiple collecting frames 2011, and two are located on both sides of multiple anode plates 102 in a group. A scraper 2012 is fixed on one side of the collecting frame 2011. One side of the scraper 2012 is inclined upward, and one side of the scraper 2012 fits the shape of the anode plate 102.

[0030] When the collection frame 2011 moves from bottom to top, the scraper 2012 will fit with the anode plate 102, and as the scraper 2012 moves upward, the dust on the anode plate 102 will be scraped off, thereby completely removing the dust on the anode plate 102 to avoid dust residue. The fallen dust will enter the collection frame 2011 along the inclined surface of the scraper 2012, and the dust will be collected by the collection frame 2011 to prevent the dust from floating in the box body 101 and being rolled up again by the airflow, thereby causing secondary dust.

[0031] When the collecting frame 2011 moves upward and downward, the scraper 2012 will not contact the anode plate 102, thereby preventing the scraper 2012 from scraping dust off the anode plate 102 and causing the dust to float inside the box 101.

[0032] A support plate 2013 is provided inside the collection frame 2011, and a support shaft 2014 is fixed inside the support plate 2013. The support shaft 2014 is rotatably connected to the collection frame 2011 through a bearing. The support plate 2013 is used to support and intercept dust. When the collection frame 2011 moves to the bottom of the box body 101, the support plate 2013 will release the restriction and open downward under the pressure of the dust. At this time, the dust will fall directly into the ash hopper, thereby preventing the dust from floating inside the box body 101 and causing secondary dust.

[0033] A torsion spring 2015 is fixed to the outside of the support shaft 2014, and the other end of the torsion spring 2015 is fixed to the collection frame 2011. When the dust is emptied and the pressure on the support plate 2013 disappears, the torsion spring 2015 can drive the support shaft 2014 and the support plate 2013 to rotate upward, so that the support plate 2013 is closed with the collection frame 2011 again.

[0034] Example 2 Reference Figure 3-Figure 6 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.

[0035] Specifically, the cleaning component 200 also includes a driving member 202, which includes a reciprocating roller 2021 rotatably connected to the inside of the box body 101. A motor 2022 is fixed on the top of the box body 101, and the output shaft of the motor 2022 is fixed to the reciprocating roller 2021. Reciprocating rollers 2021 are provided on both sides of each collection frame 2011. The reciprocating rollers 2021 on both sides of an anode plate 102 are connected by a belt drive, so that one motor 2022 can drive the two reciprocating rollers 2021 to rotate at the same time.

[0036] A clamping block 2023 is fixed on one side of the collection frame 2011, and a positioning block 2024 is sleeved on the outside of the reciprocating roller 2021. A clamping block 2023 is fixed on both sides of a collection frame 2011, and a fixed shaft 2025 is fixed in the positioning block 2024. The fixed shaft 2025 engages with the reciprocating roller 2021, and a clamping slot 2024-1 is provided on the positioning block 2024. The clamping block 2023 and the clamping slot 2024-1 are both T-shaped, and the clamping block 2023 is movably connected to the clamping slot 2024-1.

[0037] When the reciprocating roller 2021 rotates, it drives the positioning block 2024 to move up and down through the fixed shaft 2025, and then drives the clamping block 2023 and the collecting frame 2011 to move up and down through the positioning block 2024.

[0038] Specifically, the dust cleaning component 200 also includes a switching member 203, the number of which corresponds to the card block 2023, and the switching member 203 includes a force block 2031 fixed to the bottom of the card block 2023, and one side of the bottom of the force block 2031 is inclined. A sliding groove is provided at the bottom of the positioning block 2024, and the force block 2031 is movably connected to the sliding groove. An extrusion block 2032 is fixed to the bottom wall of the box body 101.

[0039] When the collection frame 2011 moves to the bottom of the box body 101, the extrusion block 2032 will contact the force block 2031 and squeeze the inclined surface of the force block 2031. The cooperation of the two drives the clamping block 2023 to move, and the clamping block 2023 drives the collection frame 2011 to move, so that the collection frame 2011 can drive the scraper 2012 to fit with the anode plate 102, so that when the collection frame 2011 moves up, the scraper 2012 can clean the anode plate 102.

[0040] A first spring 2033 is fixed to one side of the block 2023, and the other end of the first spring 2033 is fixed to the inner wall of the slot 2024-1. When the collection frame 2011 moves to the upper part of the box body 101 and the block 2023 is unlocked, the first spring 2033 can apply a thrust to the block 2023, and the collection frame 2011 and the scraper 2012 are driven to separate from the anode plate 102 through the block 2023.

[0041] Specifically, the cleaning component 200 also includes a limiting member 204, the limiting member 204 includes a limiting column 2041, a groove 2023-1 is provided on the blocking block 2023, the limiting column 2041 is located in the groove 2023-1, a limiting hole 2024-2 is provided on the positioning block 2024, and a second spring 2042 is fixed to the bottom end of the limiting column 2041, and the bottom end of the second spring 2042 is fixed to the inner wall of the groove 2023-1.

[0042] When the scraper 2012 is in contact with the anode plate 102, the limiting post 2041 will engage with the limiting hole 2024-2. The cooperation between the two can lock the position of the block 2023 and the collection frame 2011, so that the scraper 2012 will not deviate when it moves upward and cleans the anode plate 102, thereby being able to stably clean the anode plate 102.

[0043] When the limiting post 2041 is aligned with the limiting hole 2024 - 2 , the second spring 2042 applies a thrust to the limiting post 2041 , thereby enabling the limiting post 2041 to engage with the limiting hole 2024 - 2 .

[0044] Specifically, a push column 2043 is fixed on the top wall of the box body 101, and the push column 2043 is coaxial with the limiting hole 2024-2. When the collection frame 2011 moves to the upper part of the box body 101, the push column 2043 will be inserted into the limiting hole 2024-2 and push the limiting column 2041 to separate from the limiting hole 2024-2, thereby releasing the restriction on the block 2023.

[0045] Example 3 Reference Figure 3 、 Figure 5 、 Figure 7 and Figure 8 , which is the third embodiment of the present invention, and is based on the first two embodiments.

[0046] Specifically, the dust cleaning component 200 also includes a locking piece 205. A locking piece 205 is provided on both sides of a collection frame 2011. The locking piece 205 includes an insertion rod 2051 located on one side of the collection frame 2011. A slot 2014-1 is provided on the support shaft 2014. The insertion rod 2051 is inserted into the slot 2014-1. Through the cooperation of the two, the support shaft 2014 and the support plate 2013 can be locked so that the support plate 2013 will not open when it is under pressure from dust.

[0047] A stabilizing frame 2052 is fixed to one side of the collecting frame 2011 , and the inserting rod 2051 is movably connected to the stabilizing frame 2052 . The stabilizing frame 2052 is used to support and position the inserting rod 2051 .

[0048] Specifically, a fixing plate 2053 is fixed to one side of the insertion rod 2051, a third spring 2054 is fixed to one side of the fixing plate 2053, and the other end of the third spring 2054 is fixed to the stabilization frame 2052. The third spring 2054 is used to apply tension to the fixing plate 2053 and the insertion rod 2051, thereby making the insertion rod 2051 and the slot 2014-1 more tightly engaged.

[0049] Specifically, an extrusion rod 2055 is fixed to the inner bottom wall of the box body 101, and a force-bearing groove 2051-1 is opened on the insertion rod 2051, and the inner wall of the force-bearing groove 2051-1 is inclined.

[0050] When the extrusion block 2032 squeezes the inclined surface of the force-bearing block 2031 and causes the collection frame 2011 to move, the position of the force-bearing groove 2051-1 will be vertical to the extrusion rod 2055. As the collection frame 2011 continues to move downward, the extrusion rod 2055 can squeeze the inclined surface of the inner wall of the force-bearing groove 2051-1. Through the cooperation of the two, the insertion rod 2051 is driven to separate from the slot 2014-1, thereby releasing the restriction on the support plate 2013.

[0051] Specifically, the cleaning component 200 also includes a vibrating member 206, which includes a support block 2061 fixed to one side of the positioning block 2024, and a rotating sleeve 2062 is rotatably connected to the support block 2061 through a bearing, and an elastic rod 2063 is fixed to the outside of the rotating sleeve 2062. The elastic rod 2063 itself is elastic, and a vibrating ball 2064 is fixed to the end of the elastic rod 2063. The vibrating ball 2064 has a certain weight. The number of elastic rods 2063 and vibrating balls 2064 is multiple, and they are evenly distributed in a ring shape on the outside of the rotating sleeve 2062.

[0052] Specifically, a fixing column 2065 is fixed to the inner bottom wall of the box body 101 , a spiral groove 2065 - 1 is formed on the fixing column 2065 , and a positioning shaft 2066 is fixed to the inner side of the rotating sleeve 2062 .

[0053] When the collection frame 2011 moves to the bottom of the box body 101, the fixed column 2065 will be inserted into the rotating sleeve 2062, and the positioning shaft 2066 will enter the spiral groove 2065-1. As the collection frame 2011 moves downward, the positioning shaft 2066 will slide along the inside of the spiral groove 2065-1 and drive the rotating sleeve 2062 to rotate. The rotating sleeve 2062 drives the rapping ball 2064 to rap the collection frame 2011 and make the collection frame 2011 vibrate. Then, after the support plate 2013 is opened downward, the vibration of the collection frame 2011 can quickly discharge the dust inside it, and at the same time prevent dust from remaining on the inner wall of the collection frame 2011.

[0054] During use, when the anode plate 102 needs to be cleaned, the motor 2022 is started to drive the reciprocating roller 2021 to rotate. When the reciprocating roller 2021 rotates, the positioning block 2024 is driven to move forward through the fixed shaft 2025, and the positioning block 2024 drives the card block 2023 and the collection frame 2011 to move forward through the positioning block 2024.

[0055] When the collection frame 2011 moves from bottom to top, the scraper 2012 will fit with the anode plate 102, and as the scraper 2012 moves upward, the dust on the anode plate 102 will be scraped off, thereby completely removing the dust on the anode plate 102 to avoid dust residue. The fallen dust will enter the collection frame 2011 along the inclined surface of the scraper 2012, and the dust will be collected by the collection frame 2011 to prevent the dust from floating in the box body 101 and being rolled up again by the airflow, thereby causing secondary dust.

[0056] When the collection frame 2011 moves to the upper part of the box body 101, the push column 2043 will be inserted into the limiting hole 2024-2, and push the limiting column 2041 to separate from the limiting hole 2024-2, thereby releasing the restriction on the block 2023, and applying a thrust to the block 2023 through the first spring 2033, and driving the collection frame 2011 and the scraper 2012 to separate from the anode plate 102 through the block 2023.

[0057] When the collecting frame 2011 moves to the bottom of the box body 101, the extrusion block 2032 will contact the force block 2031 and squeeze the inclined surface of the force block 2031. The cooperation between the two drives the clamping block 2023 to move, and the clamping block 2023 drives the collecting frame 2011 to move, so that the collecting frame 2011 can drive the scraper 2012 to fit with the anode plate 102.

[0058] At the same time, the position of the force groove 2051-1 will be vertical to the squeezing rod 2055. As the collection frame 2011 continues to move downward, the squeezing rod 2055 will squeeze the inner wall slope of the force groove 2051-1. Through the cooperation of the two, the insertion rod 2051 and the slot 2014-1 are driven to separate, thereby releasing the restriction on the support plate 2013. At this time, the support plate 2013 will open downward due to the pressure of the dust, and allow the dust to fall directly into the ash hopper, thereby preventing the dust from floating inside the box 101 and causing secondary dust.

[0059] At the same time, the fixed column 2065 will be inserted into the rotating sleeve 2062, and the positioning shaft 2066 will enter the spiral groove 2065-1. As the collection frame 2011 moves downward, the positioning shaft 2066 will slide along the inside of the spiral groove 2065-1 and drive the rotating sleeve 2062 to rotate. The rotating sleeve 2062 drives the rapping ball 2064 to rap the collection frame 2011 and make the collection frame 2011 vibrate. After the support plate 2013 is opened downward, the vibration of the collection frame 2011 can quickly discharge the dust inside it, and at the same time prevent dust from remaining on the inner wall of the collection frame 2011.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
