Abstract
Description

[0002] In the process of industrial production, the emission of flue gas causes serious pollution to the environment. In order to reduce pollution, it is very important to effectively remove dust from the flue gas. At present, dry dust removal is a common way to treat flue gas.
[0003] In the dry dust removal process of the prior art, in order to improve the dust removal effect, the filter layer is often designed to be in a pleated shape. This design can make the passage path of the flue gas more tortuous and complex, thereby increasing the contact opportunities between the dust and the filter layer and improving the dust removal efficiency. However, this pleated filter layer has disadvantages in practical applications. When the filter layer needs to be cleaned, if a sweeping method is used, the accumulated dust is difficult to clean due to the narrow space between the pleats, and the cleaning effect is not good. If a backblowing method is used, the structural characteristics of the pleats require a greater backblowing force to blow out the accumulated dust, which increases the energy consumption of the equipment and requires more effort to adjust the backblowing parameters.

DETAILED DESCRIPTION
[0020] The present disclosure is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present disclosure, rather than to limit the present disclosure.

In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".
[0022] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this disclosure can be understood according to specific circumstances.
[0023] In the present disclosure, unless otherwise expressly specified and limited, a first feature being “above” or “below” a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them.

A first feature being “below”, “below”, and “below” a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.
[0024] In the description of this embodiment, terms such as "up", "down", "left", and "right" and other orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of description and simplification of operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present disclosure.
[0025] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.
[0026] like Figure 1 to Figure 12 As shown, it shows a dust removal device for flue gas treatment in an embodiment of the present disclosure, including a shell 1, a moving part 2, a dust removal layer body 3 and an elastic support strip 4, the shell 1 has an air inlet 101 and an air outlet 102, the moving part 2 is slidably arranged relative to the shell 1 and is located in the shell 1, the moving parts 2 are symmetrically arranged with two and are configured to move closer to or away from each other, the two ends of the dust removal layer body 3 are respectively arranged on the two moving parts 2, the elastic support strip 4 is embedded in the dust removal layer body 3, and the elastic support strip 4 is configured to be corrugated in the initial state to support the dust removal layer body 3 in a corrugated shape; The dust removal layer 3 is configured to be stretched flat together with the elastic support strip 4 when the two moving parts 2 move away from each other, and to restore the corrugated shape together with the elastic support strip 4 under the action of the elastic force of the elastic support strip 4 when the two moving parts 2 move toward each other.
[0027] For example, Figure 2~Figure 10 As shown, in actual operation, the two moving parts 2 are initially in a state of being close to each other. At this time, the elastic support strip 4 embedded in the dust removal layer body 3 is corrugated, and will support the dust removal layer body 3 to be corrugated by its elastic force. The smoke containing dust enters from the air inlet 101 of the shell 1. When passing through the dust removal layer body 3, the passage path of the smoke becomes complicated, and the smoke contacts the dust removal layer body 3, thereby being effectively intercepted, and finally the smoke is discharged from the air outlet 102.
[0028] When the dust removal layer 3 needs to be cleaned, the two moving parts 2 are driven to slide in the direction away from each other. In this process, the elastic support strips 4 are stretched, and the originally corrugated dust removal layer 3 is gradually stretched flat. At this time, the cleaning tool can more conveniently clean the stretched surface of the dust removal layer 3. Since there is no obstruction of wrinkles, the accumulated dust can be easily and thoroughly cleaned. After the cleaning work is completed, the two moving parts 2 are controlled to approach each other again. The elastic support strips 4 restore the corrugated shape under the action of their own elastic force, and then drive the dust removal layer 3 to restore the corrugated shape, so that the dust removal device can be put into normal dust removal work again.
[0029] The elastic support strip 4 is a metal strip with elasticity, and is embedded in the dust removal layer 3 along the sliding direction of the moving part 2. Under normal working conditions, the dust removal layer 3 is corrugated, and dust can be more fully intercepted, thereby improving the dust removal efficiency. By designing the moving part 2 as a slidable structure, the dust removal layer 3 can be stretched flat during cleaning, avoiding the problem of dust accumulation between folds that is difficult to clean, and the cleaning process becomes simple and easy to operate.
[0030] In some examples, there are multiple elastic support bars 4, and the multiple elastic support bars 4 are arranged parallel to each other.
[0031] For example, Figure 6 and Figure 7 As shown, multiple elastic support strips 4 arranged in parallel to each other can support the dust removal layer 3 from multiple positions, avoiding the situation where the stability of the overall structure is affected by the failure of a single support strip. When restoring the corrugated shape, it can also ensure that the entire dust removal layer 3 is evenly restored to the corrugated shape, dispersing the pressure it bears and reducing the risk of fatigue damage to the elastic support strips 4.
[0032] In some examples, it further includes a rotating member 5, a swing arm 6 and a flexible scraper 7, wherein the rotating member 5 is rotatably disposed in the housing 1, and the moving member 2 is slidably disposed on the rotating member 5 along the radial direction of the rotating member 5; The swing arm 6 is swingably disposed on the inner wall of the shell 1 , and the flexible scraper 7 is disposed on the swing arm 6 . The flexible scraper 7 is configured to be able to contact the dust removal layer 3 in a stretched flat state under the drive of the swing arm 6 .
[0033] For example, Figure 6 As shown, when cleaning the dust removal layer 3, firstly, the two moving members 2 are slid away from each other along the radial direction of the rotating member 5, and the elastic support strip 4 is stretched, thereby flattening the dust removal layer 3. Then, the external driving force drives the rotating member 5 to rotate. Since the moving member 2 is arranged on the rotating member 5, the rotation of the rotating member 5 drives the moving member 2 and the stretched dust removal layer 3 to rotate together.
[0034] At the same time, the swing arm 6 starts to swing, driving the flexible scraper 7 to contact the bottom surface of the dust removal layer 3 in a stretched state. With the rotation of the dust removal layer 3, the accumulated dust is scraped off the surface of the dust removal layer 3 to complete the cleaning. After the cleaning is completed, the moving parts 2 approach each other, and the dust removal layer 3 restores the corrugated shape under the action of the elastic support strips 4. The dust removal layer 3 is cleaned by the coordinated work of the rotating part 5, the swing arm 6 and the flexible scraper 7.
[0035] In some examples, the movable member 2 has a push-up slope 201, and the push-up slope 201 is configured to contact and push the swing arm 6 when the two movable members 2 move away from each other, so that the flexible scraper 7 on the swing arm 6 contacts the dust removal layer 3 in a stretched state. It also includes a spring 18, and the two ends of the spring 18 act on the swing arm 6 and the inner wall of the shell 1 respectively, so as to provide a force to move the swing arm 6 away from the dust removal layer 3.
[0036] For example, Figure 2-Figure 9 As shown, when the dust removal layer 3 is cleaned, the two moving parts 2 slide away from each other, and the pushing inclined surface 201 set on the moving part 2 gradually approaches the swing arm 6.
[0037] The middle part of the swing arm 6 is hinged to the inner wall of the shell 1, and a flexible scraper 7 is arranged at the bottom end of the swing arm 6, and the top end is used to contact the push-up slope 201. Under normal conditions, the swing arm 6 is parallel to the inner wall of the shell 1. When the push-up slope 201 contacts the top end of the swing arm 6, the push-up slope 201 applies a thrust to the swing arm 6, and the swing arm 6 starts to swing until the flexible scraper 7 contacts the bottom surface of the dust removal layer body 3 in a stretched flat state. The linkage between the sliding of the moving part 2 and the swinging of the swing arm 6 is realized by the push-up slope 201, making the cleaning process simpler. After cleaning, the moving part 2 is reset, and the push-up slope 201 is separated from the contact with the swing arm 6. Under the action of the spring 18, the swing arm 6 returns to a state parallel to the inner wall of the shell 1.
[0038] During cleaning, the rotating member 5 drives the moving member 2 to rotate, and the moving member 2 is in the shape of an arc. During the rotation of the dust removal layer 3, the moving member 2 always abuts against the swing arm 6, so that the flexible scraper 7 always fits the bottom surface of the dust removal layer 3, and the accumulated dust is scraped off the surface of the dust removal layer 3. Because the moving member 2 is not a complete circle, in order to prevent the moving member 2 from being out of contact with the swing arm 6, the rotation of the rotating member 5 is a reciprocating rotation in both directions, and is maintained within a certain angle, so as to ensure that the moving member 2 can always contact the swing arm 6 during the rotation.
[0039] In some examples, a water tank 8, a water pipe 9 and a moisturizing nozzle 10 are also included. The water tank 8 is used to be arranged next to the shell 1. The water pipe 9 is arranged through the side wall of the shell 1 and is located above the dust removal layer 3. The moisturizing nozzle 10 is arranged on the water pipe 9 and is connected to the water pipe 9. The moisturizing nozzle 10 is used to intermittently spray liquid onto the dust removal layer 3.
[0040] For example, Figure 2 As shown, the moisturizing nozzle 10 is set to an intermittent working mode. The moisturizing nozzle 10 works once every preset time interval, and the amount of water sprayed each time is certain to ensure that the moisture content of the dust removal layer 3 is maintained within a certain range, preferably less than 15%, to ensure that the dust removal layer 3 always has good air permeability.
[0041] After the liquid is sprayed, a layer of liquid film will form on the fiber surface of the dust removal layer 3. This reduces the degree of wear on the fiber by dust, prolongs the replacement cycle of the dust removal layer 3, and makes it easier for dust particles to be adhered to the liquid film when the smoke passes through, thereby enhancing the dust adsorption capacity of the dust removal layer 3 and improving the dust removal efficiency. In addition, the dust removal layer 3 has a certain moisture content, which can reduce the dryness of the intercepted dust accumulation, and can also reduce dust during cleaning, thereby reducing pollution to the environment.
[0042] In some examples, an air guide cover 11 is disposed in the shell 1 , one end of the air guide cover 11 is connected to the air inlet 101 , and the other end of the air guide cover 11 is disposed on the lower surface of the dust removal layer body 3 .
[0043] For example, Figure 2 and Figure 4 As shown, one end of the air guide hood 11 is connected to the air inlet 101, and the other end is covered on the lower surface of the dust removal layer 3. After the smoke enters the air guide hood 11, it is restricted to flow inside it. The air guide hood 11 can guide the smoke to the dust removal layer 3, so that the smoke impacts the lower surface of the dust removal layer 3 in a relatively stable state. The corrugated dust removal layer 3 removes the smoke and finally discharges it from the air outlet 102.
[0044] In some examples, a side wall of the air guide cover 11 is provided with a clearance hole 12 , and the clearance hole 12 is configured to allow the swing arm 6 to pass through when the swing arm 6 swings toward a direction close to the dust removal layer body 3 .
[0045] For example, Figure 2 and Figure 4 As shown, when the swing arm 6 swings, it can pass through the clearance hole 12 opened on the side wall of the wind guide cover 11 to avoid interference with the wind guide cover 11, so that the swing arm 6 can approach and contact the dust removal layer body 3 as required, ensuring the normal cleaning action. The clearance hole 12 meets the space requirement for the swing arm 6 to swing without affecting the wind guide cover 11 to guide the smoke.
[0046] In some examples, the movable member 2 has a positioning hole 13, the rotating member 5 has two groups of threaded holes 14, and also includes a positioning bolt 15. The positioning bolt 15 passes through the positioning hole 13 and is threadedly connected to one group of the threaded holes 14, and is used to lock the position of the movable member 5 when stretching or unstretching the dust removal layer 3.
[0047] For example, Figure 6-Figure 10 As shown, when the dust removal layer 3 needs to be cleaned, the two moving parts 2 slide away from each other to evenly flatten the dust removal layer 3. At this time, the positioning hole 13 on the moving part 2 moves to align with a group of threaded holes 14. The positioning bolt 15 passes through the positioning hole 13 and is screwed into the group of threaded holes 14 to fix the moving part 2 in the state where the dust removal layer 3 is stretched flat.
[0048] After cleaning is completed, the moving parts 2 slide close to each other, and the dust removal layer body 3 returns to the corrugated shape. At this time, the positioning holes 13 on the moving part 2 are aligned with the other group of threaded holes 14. The positioning bolts 15 pass through the positioning holes 13 and are screwed into the group of threaded holes 14 to position the moving part 2 at this position. The positioning bolts 15 cooperate with the positioning holes 13 and the threaded holes 14 to achieve the locking of the position of the moving part 2 under different working conditions.
[0049] In some examples, the shell 1 has an operating chamber 103, the swing arm 6, the rotating part 5 and the moving part 2 are all located in the operating chamber 103, the side wall of the shell 1 has an inspection port 104, the inspection port 104 is connected to the operating chamber 103, and an inspection door 105 is hinged in the inspection port 104, and the inspection door 105 is used to open or close the inspection port 104.
[0050] For example, Figure 2 and Figure 4As shown, during daily operation, the swing arm 6, the rotating member 5 and the moving member 2 all work in the operating chamber 103. When cleaning work is required, first open the inspection door 105 to connect the operating chamber 103 with the outside. Then manually adjust the moving member 2, slide it to the position where the dust removal layer body 3 is stretched flat, and then pass the positioning bolt 15 through the positioning hole 13 and screw it into the corresponding threaded hole 14. An inspection port 104 is set on each side of the housing 1 for controlling the two moving members 2 respectively.
[0051] In some examples, a rotating driving member 16 and a driving gear 17 are further included, wherein the rotating driving member 16 is disposed on the outer wall of the shell 1, and the driving gear 17 is rotatably disposed in the shell 1, the rotating member 5 is a ring gear, and the driving gear 17 is meshed with the ring gear, and the rotating driving member 16 is drivingly connected to the driving gear 17 for driving the ring gear to rotate.
[0052] For example, Fig.12 As shown, the rotary drive member 16 is mounted on the outer wall of the housing 1, and its power output shaft is connected to the central axis of the driving gear 17 through a pair of bevel gears to ensure effective power transmission. The rotary drive member 16 drives the driving gear 17 to rotate in the housing 1, thereby driving the ring gear to rotate. By controlling the direction of the rotary drive member 16, the direction of the ring gear can be adjusted to match the needs of the cleaning action.
[0053] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure rather than to limit it. Although the present disclosure 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 disclosure may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present disclosure, which should be included in the scope of the claims of the present disclosure.
