It should also be understood that terms defined in general dictionaries, such as general dictionaries, should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an idealized or extremely formal sense, unless explicitly defined herein.

[0030] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0031] like Figures 1 to 3 As shown, the flue gas dust removal device disclosed in Example 1 of the present application includes a dust bin assembly 10, a dust bag 20 and a cleaning assembly 30. The dust bag 20 is connected to the dust bin assembly 10 and is arranged in the dust bin assembly 10. The cleaning assembly 30 includes a frame structure 31 and a brush structure 32. The frame structure 31 is movably connected to the dust bin assembly 10 and the moving direction is parallel to the dust bag 20. The brush structure 32 is connected to the frame structure 31, and the brush structure 32 is arranged on the circumferential outer side of the dust bag 20.

[0032] By applying the technical solution of the first embodiment, when there are too many particles attached to the dust bag 20, the control frame structure 31 is moved in a direction parallel to the dust bag 20. Since the brush structure 32 is arranged on the outer side of the dust bag 20 in the circumferential direction, the particles are separated from the dust bag 20 by the brush structure 32 and fall to the bottom of the dust bin assembly 10 under the action of gravity, thereby cleaning the dust bag 20. This cleaning method does not require opening the dust bin assembly 10 and disassembling the dust bag 20, and has high working efficiency. The technical solution of the first embodiment effectively solves the problem of low dust removal efficiency in the flue gas dust removal process in the prior art.

[0033] like Figures 1 to 3 As shown, in the technical solution of the first embodiment, the dust bin assembly 10 includes a dust bin structure 11 and a guide rail structure 12. The guide rail structure 12 is connected to the dust bin structure 11 and is arranged in the dust bin structure 11. The guide rail structure 12 is parallel to the dust bag 20 and both are arranged in the vertical direction. The frame structure 31 is movably connected to the guide rail structure 12. The guide rail structure 12 guides and limits the movement of the cleaning assembly 30 to avoid deviation of the movement of the cleaning assembly 30. The guide rail structure 12 is arranged in parallel with the dust bag 20, ensuring that the cleaning assembly 30 moves in a direction parallel to the dust bag 20, avoiding the cleaning assembly 30 from affecting the normal operation of the dust bag 20.

[0034] like Figure 1 As shown, in the technical solution of the first embodiment, the guide rail structure 12 includes a guide section 121 and a limit section 122, the limit section 122 is connected to the guide section 121 and is arranged at both ends of the guide section 121, the frame structure 31 is movably connected to the guide section 121, and the projection of the guide section 121 in the vertical direction is located within the projection of the limit section 122 in the vertical direction. The setting of the limit section 122 prevents the frame structure 31 from moving out of the range of the guide rail structure 12, and prevents the frame structure 31 from falling off. The cross-sectional shape of the guide section 121 is U-shaped, and the frame structure 31 has a connecting portion, which is arranged in the guide section 121 and can be moved relative to the guide section 121. The U-shaped guide section 121 has a better limiting effect, which further prevents the frame structure 31 from falling off.

[0035] like Figure 1 As shown, in the technical solution of the first embodiment, the height of the guide section 121 in the vertical direction is less than the height of the dust bag 20 in the vertical direction. The guide section 121 is arranged corresponding to the dust bag 20. Since the height of the guide section 121 in the vertical direction is less than the height of the dust bag 20 in the vertical direction, during the movement of the frame structure 31, the dust bag 20 is always located in the brush structure 32, and will not be separated, and there is no need to repeatedly install the cleaning assembly, thereby improving work efficiency.

[0036] like Figure 1 and Figure 3 As shown, in the technical solution of the first embodiment, the distance between the inner edge of the brush structure 32 and the outer wall of the dust bag 20 is 10 mm to 35 mm. A pulse generator is provided at the upper end of the dust bag 20. Controlling the pulse size and frequency of the pulse generator can improve the dust removal efficiency. When the brush structure 32 cleans the dust bag 20, starting the pulse generator is beneficial to dust cleaning. When the brush structure 32 cleans the dust on the dust bag 20, the dust bag 20 shakes under the action of the pulse generator and contacts the moving brush structure 32 to complete the dust removal. When the distance between the inner edge of the brush structure 32 and the outer wall of the dust bag 20 is less than 10 cm, the cleaning component 30 encounters greater resistance during movement, making it difficult to move, and the dust bag 20 is subjected to greater external force from the cleaning component 30, making it easy to be damaged; when the distance between the inner edge of the brush structure 32 and the outer wall of the dust bag 20 is greater than 35 cm, the distance between the brush structure 32 and the dust bag 20 is far, resulting in incomplete cleaning.

[0037] like Figure 1 and Figure 3 As shown, in the technical solution of the first embodiment, the brush structure 32 includes bristles, and the bristles are made of polyetheretherketone. Polyetheretherketone has good wear resistance, corrosion resistance and high temperature resistance, is suitable for dust removal in various working environments and flue gas of various components, and has a long service life. The brush structure 32 also includes a fixing part, the bristles are connected to the fixing part, and a plurality of bristle fixing holes are provided on the fixing part. The bristles are fixed in the bristle fixing holes, and the bristles are arranged along the circumference of the dust bag 20. The fixing part is arranged along the circumference of the bristles. A plurality of dust bags 20 are provided in the dust removal bin assembly 10. The brush structure 32 is arranged one by one with the dust bag 20. A connecting rod is provided between the plurality of fixing parts. The connecting rod and the fixing part are detachably connected, such as a threaded connection, to facilitate replacement of the brush structure. The difference between the inner circle size and the outer circle size of the fixed part is 0.7mm to 15mm. When the difference is less than 0.7mm, the bristles are small in size when extended into the fixed part, the bristles are easy to fall off, and the service life of the brush structure is short; when the difference is greater than 15mm, the dust falling off the dust bag 20 is easy to accumulate on the fixed part, which is not conducive to the dust removal of the dust bag 20.

[0038] like Figure 1 and Figure 2As shown, in the technical solution of the first embodiment, the dust bin assembly 10 further includes a driving structure 13, the driving structure 13 includes a cylinder 131 and a telescopic rod 132, the telescopic rod 132 is connected to the cylinder 131, the telescopic rod 132 is parallel to the guide rail structure 12, the cylinder 131 is connected to the dust bin structure 11, and one end of the telescopic rod 132 away from the cylinder 131 is connected to the frame structure 31. The cylinder 131 controls the telescopic rod 132 to extend and retract, thereby controlling the cleaning assembly 30 to move along the guide rail structure 12, and the cylinder 131 is arranged on the outside of the dust bin structure 11 to prevent dust from entering the cylinder 131 and affecting the normal operation of the cylinder 131.

[0039] like Figure 1 As shown, in the technical solution of the first embodiment, the dust removal bin structure 11 further includes a collecting portion 111, the height of the collecting portion 111 in the vertical direction is lower than the height of the frame structure 31 in the vertical direction, and the size of the collecting portion 111 decreases continuously in the direction from close to far away from the frame structure 31. The setting of the collecting portion 111 facilitates the collection of dust falling from the dust removal bag 20, and the size of the collecting portion 111 decreases continuously in the direction from close to far away from the frame structure 31, and this structure facilitates the gathering of scattered dust together.

[0040] like Figure 1 As shown, in the technical solution of the first embodiment, the collecting part 111 has a shell 1111 and a hatch 1112, and the hatch 1112 has an open state away from the shell 1111 and a closed state close to the shell 1111. When the hatch 1112 is opened, the cleaned dust can be discharged from the dust removal bin structure 11, so as to avoid excessive dust accumulation in the collecting part 111, which affects the subsequent fume dust removal work.

[0041] The difference between the technical solution of the second embodiment and the technical solution of the first embodiment is that the driving structure 13 also includes a motor and a screw, the screw is connected to the output shaft of the motor and is arranged parallel to the dust bag 20, and the frame structure 31 has a threaded hole, and the screw matches the threaded hole. The movement of the frame structure 31 is controlled by the screw transmission method, and the transmission method is more stable.

[0042] The difference between the technical solution of the third embodiment and the technical solution of the first embodiment is that the guide rail structure 12 and the driving structure 13 are respectively arranged on different sides of the frame structure 31, which further ensures that the frame structure 31 is subjected to uniform force when moving and avoids the frame structure 31 from deflecting and flipping.

[0043] The difference between the technical solution of Example 4 and the technical solution of Example 1 is that the cleaning component 30 also includes a vibration motor, which is connected to the frame structure 31. The vibration motor has a rotor and an eccentric wheel inside. The rotor is connected to the eccentric wheel to drive the eccentric wheel to rotate. The center of the circle and the center of gravity of the eccentric wheel do not coincide with each other, so the frame structure 31 will vibrate when it rotates. The frame structure 31 vibrates, and the dust accumulated on the brush structure 32 is shaken off, thereby further improving the cleaning ability of the cleaning component 30.

[0044] Based on the above, it can be seen that the telescopic cylinder (driving structure 13) is installed on the top of the dust removal bin and fixed with a fixing device. The telescopic rod of the cylinder is connected to the cleaning device (cleaning assembly 30). The cylinder 131 is extended and retracted to drive the cleaning device to move up and down on the limit track device (guide rail structure 12). The brush (brush structure 32) on the cleaning device is used to clean the dust compacted on the dust filter bag (dust bag 20). The brushed dust is collected and processed through the conical bottom (collection part 111). The telescopic cylinder device is connected to the flue gas treatment system, and the cylinder is controlled by the PLC control valve. The timing signal is set to regularly clean the dust filter bag.

[0045] So far, the embodiments of the present application have been described in detail. In order to avoid obscuring the concept of the present application, some details known in the art are not described. Based on the above description, those skilled in the art can fully understand how to implement the technical solution of the present application.

[0046] Although some specific embodiments of the present application have been described in detail by way of examples, it should be understood by those skilled in the art that the above examples are for illustration only and are not intended to limit the scope of the present application. It should be understood by those skilled in the art that the above embodiments may be modified or some technical features may be replaced by equivalents without departing from the scope and spirit of the present application. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there is no structural conflict.
