Technical Field

[0001] The utility model relates to the technical field of dust removal, and in particular to a flue gas bag dust collector for incineration. Background Art

[0002] Garbage is solid waste generated in human daily life and production. Due to its large discharge volume, complex and diverse composition, and its pollution, resource and social nature, it needs to be harmlessly, resourcefully, reduced and socially treated. If it is not properly treated, it will pollute the environment, affect environmental hygiene, waste resources, damage production and living safety, and destroy social harmony. The widely used garbage disposal methods today are sanitary landfill, high-temperature composting and incineration. When garbage is treated by incineration, a large amount of garbage incineration flue gas will be generated.

[0003] The existing bag filter for incineration flue gas refers to the patent document CN217247474U. The device proposed in the patent document can cool the exhaust gas. However, in the actual dust removal process, it is found that the above-mentioned device filters out the dust particles inside the garbage incineration flue gas by filtering. As the filtering and dust removal work proceeds, a large amount of dust will accumulate on the filter component, which will easily affect the dust removal quality on the one hand and be inconvenient to clean on the other hand. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example 1

[0025] like Figure 1 to Figure 5As shown, this embodiment proposes a flue gas bag filter for incineration, including a dust removal box 1, a partition 2 and a filter plate 4 are fixedly connected to the interior of the dust removal box 1, and a plurality of filter bags 3 are installed on the outer surface of the partition 2. By setting the filter bags 3, the flue gas can enter from the bottom end thereof for filtration, and the filtered dust will be accumulated on the surface of the filter bags 3, and then discharged through the pipe at the top of the filter bags 3. The pipe at the top of the filter bags 3 is located on the upper surface of the partition 2, as shown in FIG. Figure 3 shown.

[0026] In this embodiment, by providing the filter plate 4, the smoke discharged through the top of the filter bag 3 can be further filtered, so as to achieve the effect of successively treating the smoke, making the smoke treatment of the device more refined.

[0027] A dust handling mechanism 5 is provided between the partition 2 and the filter plate 4. The dust handling mechanism 5 includes two brackets 501 fixedly connected to the inner wall of the dust removal box 1. The inner wall of each bracket 501 is rotatably connected to a reciprocating screw 502. The outer surface of each reciprocating screw 502 is threadedly connected to a sleeve block 503. The outer surface of each sleeve block 503 is fixedly connected to a rubber column 505.

[0028] Preferably, four limiting rods 504 are installed between the partition plate 2 and the filter plate 4 , and the two ends of the two sleeve blocks 503 are slidably sleeved on the outer surfaces of the four limiting rods 504 .

[0029] When the reciprocating screw 502 rotates, the sleeve block 503 threadedly connected to its outer surface will reciprocate up and down. When the sleeve block 503 reciprocates up and down, the rubber column 505 will reciprocate up and down, so that the rubber column 505 can intermittently knock on the upper surface of the partition 2 and the bottom surface of the filter plate 4.

[0030] During the knocking process of the rubber column 505, the partition 2 and the filter plate 4 will generate appropriate vibrations. The vibration of the partition 2 can shake off the dust filtered and accumulated on the surface of the filter bag 3, and the vibration of the filter plate 4 can prevent the dust from clogging the filter holes on its surface. In this way, it is more convenient to clean the dust accumulated inside the device without spending much time and energy.

[0031] A dust exhaust port 10 is installed at the bottom end of the dust removal box 1, and the input end of the dust exhaust port 10 is connected to the interior of the dust removal box 1. Four support columns 11 are fixedly connected to the bottom surface of the dust removal box 1, and the bottom surface of each support column 11 is fixedly connected to a mounting pad 12. By setting the dust exhaust port 10, the dust accumulated under the partition 2 can be easily discharged. By setting the support columns 11 and the mounting pads 12, the device can be fixed to the contact surface to achieve more stable flue gas treatment work.

[0032] The outer surface of the dust removal box 1 is installed with a first sealing door 13 and a second sealing door 14. The second sealing door 14 is located above the partition 2, and the first sealing door 13 is located below the partition 2. By setting the first sealing door 13 and the second sealing door 14, the interior of the dust removal box 1 can be regularly maintained to facilitate the reuse of the device.

[0033] Example 2

[0034] like Figure 3 to Figure 5 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes a dust handling mechanism 5, and a driving mechanism 6 is provided on the outside of the dust handling mechanism 5. The driving mechanism 6 includes a small motor 601. The small motor 601 is installed on the bottom surface of the right bracket 501 among the two brackets 501, and the output shaft end of the small motor 601 is fixedly connected to the bottom end of the corresponding bracket 501. By setting the small motor 601, the corresponding bracket 501 can be driven to rotate, thereby providing a power source for the device.

[0035] In this embodiment, the top ends of the two reciprocating screw rods 502 are fixedly connected with sprockets 602 , a chain 603 is provided between the partition plate 2 and the filter plate 4 , and the two sprockets 602 are connected in transmission via the chain 603 .

[0036] By setting up the sprocket 602 and the chain 603, when the small motor 601 is started, it will drive the corresponding bracket 501 to rotate. When the corresponding bracket 501 rotates, the sprocket 602 fixed on the top will rotate, and then the chain 603 will drive the sprocket 602 and the bracket 501 on the other side to rotate, thereby achieving the effect of rational use of resources.

[0037] In this way, by driving the small motor 601, the two reciprocating screw rods 502 can be rotated at the same time. When the two reciprocating screw rods 502 rotate at the same time, the two sleeve blocks 503 can reciprocate up and down at the same time, so that the corresponding rubber columns 505 intermittently knock on the partition 2 and the filter plate 4, thereby realizing automated cleaning of the dust accumulated inside the dust removal box 1, which is more practical.

[0038] An air inlet 8 and an air outlet 9 are installed on the outer surface of the dust removal box 1. The air inlet 8 is located below the filter bag 3, and the air outlet 9 is located above the filter plate 4. By setting the air inlet 8, the smoke generated by incineration can be introduced into the device for treatment, and then the treated smoke can be discharged to the outside through the air outlet 9.

[0039] A guide plate 7 is fixedly connected to the inner wall of the dust removal box 1, and the guide plate 7 is arranged on one side of the output end of the air inlet 8. By setting the guide plate 7, the flue gas delivered from the air inlet 8 can be guided so that the flue gas can flow downward first and then be transported upward. This can make the dust with larger mass fall down, making it convenient to gradually process the flue gas.

[0040] Working principle: When removing the flue gas, the flue gas is discharged into the interior of the dust removal box 1 through the air inlet 8. At this time, the guide plate 7 will guide the flue gas to transport the flue gas downward. In this process, the dust with larger mass can fall directly, and then the flue gas will be transported upward. At this time, the flue gas can be filtered through several filter bags 3 before it can continue to be transported upward. The flue gas filtered by the filter bags 3 will pass through the filter plates 4 for final filtration, and then be discharged to the outside through the air outlet 9. At this time, the dust contained in the flue gas will accumulate on the surface of the filter bags 3, and a small amount of dust will also adhere to the surface of the filter plates 4. Therefore, it is necessary to deal with the dust accumulated in the dust removal box 1, and then it is necessary to open the dust discharge port 10 and start the small motor 601. When the small motor 601 is started, it will first drive the corresponding reciprocating screw 502 to rotate. When the reciprocating screw 502 rotates, the sprocket 602 fixedly connected to its top will also rotate. The chain 603 provided can drive the sprocket 602 and the reciprocating screw rod 502 on the other side to rotate, so that the two reciprocating screw rods 502 can be rotated at the same time with the help of a power source. When the two reciprocating screw rods 502 rotate at the same time, the two sleeve blocks 503 can be made to reciprocate up and down, so that the rubber column 505 fixedly connected to the surface of the sleeve block 503 will intermittently knock on the surface of the partition 2 and the filter plate 4, so that the surface of the partition 2 and the filter plate 4 will vibrate, and the dust accumulated on the surface of the filter bag 3 can be shaken off by the generated vibration, and the shaken off dust will be discharged to the outside through the dust discharge port 10, and the vibration of the filter plate 4 can prevent tiny dust from clogging the filter holes on the surface of the filter plate 4, and a small amount of tiny dust will fall on the upper surface of the partition 2, and these dusts will not affect the dust removal effect of the device, and can be cleaned up when the interior of the dust removal box 1 is maintained through the first sealing door 13 and the second sealing door 14 in the later stage.

[0041] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
