Description

Technical Field

[0001] The invention belongs to the technical field of flue gas filtering, and in particular relates to a flue gas filtering device with a sonic soot blower. Background Art

[0002] The boiler flue is a pipe for exhausting smoke and taking in air from an industrial furnace. It is designed to guide and discharge the exhaust gas generated during the combustion process of the boiler, which contains smoke and other harmful substances. The flue system usually includes equipment such as chimneys and flue gas purifiers. The chimney is responsible for discharging the exhaust gas to the outside, while the flue gas purifier is used to purify the harmful substances in the exhaust gas to protect the environment. In addition, the design of the boiler flue also takes into account energy saving and improvement of thermal efficiency. The boiler tail flue refers to the flue installed at the tail of the boiler for exhausting smoke. The flue gas has a higher temperature after coming out of the high-temperature kiln.

[0003] Conventional high-temperature flue gas filtering devices often experience condensation, film sticking, and phase change when filtering the above flue gas. These phenomena will cause contamination of the filter element in the filtering device, affect the high-temperature flue gas filtering effect, and also shorten the life of the filter element.

[0004] Existing filtering devices are equipped with cooling devices to cool the flue gas. However, due to the excessive fluidity of the flue gas, the cooling effect of the cooling device on the flue gas is limited. In addition, the flue gas is unevenly distributed when passing through the filter element in the filtering device, which can easily cause local blockage or melting of the filter element in the filtering device. Summary of the invention

The sliding sleeve drives all the filters to squeeze all the No. 2 springs. Under the squeezing action of the No. 2 spring, the cooling mechanism is horizontally close to the filter and the guide sleeve. This process can increase the uniformity of the cooling mechanism spraying the filter and the guide sleeve, and avoid the filter being partially overheated and causing the surface of the filter to melt;

[0022] 5. Since the guide sleeve is conical, after the driving rod contracts to a certain extent, the cooling mechanism approaches the surface of the filter under the extrusion of the guide sleeve. At this time, the cooling mechanism rotates with the central tube, and the cooling mechanism can spray the surface of the filter closely, thereby increasing the cleaning effect of the filter surface and cooling the filter surface, further preventing the filter from melting due to heat. At the same time, the brush cleans the surface of the filter to prevent the surface of the filter from being blocked. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0032] like Figure 1-Figure 6 As shown, a flue gas filtering device with a sonic soot blower provided by the present invention comprises a jacket 1, the jacket 1 is fixedly connected with a fixing flange 3, the fixing flange 3 is provided with a threaded hole for connection, a sleeve 2 is slidably provided in the jacket 1, the jacket 1 is fixedly connected with a fixing seat 10, a driving component 4 is connected between the fixing seat 10 and the sleeve 2, the driving component 4 can drive the sleeve 2 to move in the jacket 1, and the driving component 4 is elastically connected to the sleeve 2, the sleeve 2 is fixedly connected with a plurality of filter screens 9, and a plurality of sonic soot blowers are provided on the inner wall of the sleeve 2;

[0033] The fixing seat 10 is rotatably connected with a central tube 11, and the fixing seat 10 is fixedly connected with a power assembly 5, and the power assembly 5 can drive the central tube 11 to rotate, and the central tube 11 is fixedly connected with a plurality of guide sleeves 12, and each guide sleeve 12 is provided with an air guide hole 13, all guide sleeves 12 and all filter screens 9 are arranged at intervals from each other, all guide sleeves 12 and all filter screens 9 are conical, and the opening directions of the guide sleeves 12 and all filter screens 9 are the same, and the central tube 11 passes through all filter screens 9;

[0034] A cooling mechanism 6 is arranged between the guide sleeve 12 and the filter screen 9, and the cooling mechanism 6 is slidably connected to the central tube 11. A No. 2 spring 14 is arranged between the cooling mechanism 6 and the filter screen 9 and between the cooling mechanism 6 and the guide sleeve 12. The cooling mechanism 6 is connected to the central tube 11 through a hose, and one end of the central tube 11 can be connected to an external water pump, so that the cooling mechanism 6 can perform a spraying operation.

[0035] In this embodiment, the fixed flange 3 is fixedly connected to the flue gas duct by bolts. At this time, the flue gas enters from one end of the outer jacket 1, and all the sonic soot blowers are started. The sonic soot blowers are used to prevent smoke from being adsorbed in the flue gas duct. Each filter screen 9 filters the flue gas in turn. During this process, the central tube 11 is connected to an external water pump, and the external water pump introduces water into the central tube 11. Then, the flue gas is sprayed and cooled by each cooling mechanism 6. During this process, the guide sleeve 12 on one side of the cooling mechanism 6 guides the flue gas and performs contact cooling.

[0036] Furthermore, the power assembly 5 drives the central tube 11 to rotate, and the central tube 11 drives all the cooling mechanisms 6 to rotate, thereby increasing the spraying range of the cooling mechanism 6 and the contact degree between the smoke and the water vapor. At the same time, the cooling mechanism 6 can absorb the heat on the surface of the guide sleeve 12 through the sprayed water vapor, thereby improving the cooling effect on the surface of the guide sleeve 12. The guide sleeve 12 is conical, so that the guide sleeve 12 can quickly gather the water vapor after absorbing heat and guide it downward;

[0037] The central tube 11 drives all the guide sleeves 12 to rotate, and the air guide holes 13 on the guide sleeves 12 evenly disperse the smoke to various areas of the next filter screen 9, so as to prevent the smoke from concentrating in a certain area of ​​the filter screen 9 and causing partial blockage of the filter screen 9, thereby reducing the filtering effect of the filter screen 9;

[0038] Furthermore, the driving component 4 can pull the sliding sleeve 2 to slide along the inner wall of the outer sleeve 1. During this process, the driving component 4 drives all the filter screens 9 to approach all the guide sleeves 12, all the No. 2 springs 14 are compressed, and the cooling mechanism 6 approaches the filter screens 9 and the guide sleeves 12. Since the guide sleeve 12 is conical, under the extrusion of the guide sleeve 12, the cooling mechanism 6 gradually approaches the surface of the filter screen 9. At this time, the cooling mechanism 6 rotates with the central tube 11, and the cooling mechanism 6 can spray the surface of the filter screen 9, thereby increasing the cleaning effect of the surface of the filter screen 9 and cooling the surface of the filter screen 9 to prevent the filter screen 9 from melting due to heat.

[0039] like Figure 5 As shown, a flue gas filter device with a sonic soot blower provided by the present invention, the driving assembly 4 includes a driving rod 41, a limit seat 42, a first spring 43, and a baffle 44;

[0041] In this embodiment, the drive rod 41 is started, and the drive rod 41 squeezes the No. 1 spring 43 through the baffle 44. At this time, the No. 1 spring 43 pushes the sliding sleeve 2 to slide along the inner wall of the outer sleeve 1, and the sliding sleeve 2 drives all the filter screens 9 to squeeze all the No. 2 springs 14. Under the squeezing action of the No. 2 springs 14, the cooling mechanism 6 is horizontally close to the filter screen 9 and the guide sleeve 12, thereby increasing the uniformity of the cooling mechanism 6 spraying the filter screen 9 and the guide sleeve 12, thereby avoiding local overheating of the filter screen 9 and causing the surface of the filter screen 9 to melt.

[0042] like Figure 5 As shown, a flue gas filtering device with a sonic soot blower provided by the present invention, the power assembly 5 includes a motor 51, a driving wheel 52 and a driven wheel 53;

[0043] The housing of the motor 51 is fixedly connected to the fixing seat 10 , the output shaft of the motor 51 is fixedly connected to a driving wheel 52 , the central tube 11 is fixedly connected to a driven wheel 53 , and the driven wheel 53 is meshed with the driving wheel 52 .

[0044] In this embodiment, the motor 51 is started, the motor 51 drives the driving wheel 52 to rotate, and the driving wheel 52 drives the central tube 11 to rotate by meshing with the driven wheel 53.

[0045] like Figure 6 As shown, a flue gas filtering device with a sonic soot blower provided by the present invention, the cooling mechanism 6 includes a sliding seat 61 and a rotating rod 62, the sliding seat 61 is slidably connected along the length direction of the central tube 11, and a No. 2 spring 14 is provided between the sliding seat 61 and the filter screen 9 and between the sliding seat 61 and the guide sleeve 12. The sliding seat 61 is rotatably connected to a plurality of rotating rods 62 through elastic torsion springs, and a plurality of water spray holes are provided on the rotating rods 62, and the sliding seats 61 are connected to the central tube 11 through a hose.

[0046] In this embodiment, the water flow in the central tube 11 is sprayed outward through the rotating rod 62 on the sliding seat 61 .

[0047] like Figure 6 As shown, a flue gas filtering device with a sonic soot blower provided by the present invention is shown, and multiple rows of brushes 63 are arranged on the rotating rod 62.

[0048] In this embodiment, the driving assembly 4 drives all the filter screens 9 to approach all the guide sleeves 12, all the No. 2 springs 14 are compressed, and the sliding seat 61 approaches the filter screens 9 and the guide sleeves 12. Since the guide sleeve 12 is conical, under the squeezing of the guide sleeve 12, the sliding seat 61 gradually approaches the surface of the filter screen 9. At this time, the sliding seat 61 rotates with the central tube 11, and the surface of the filter screen 9 is cleaned by the brush 63 to avoid clogging of the surface of the filter screen 9.

[0049] like Figure 1 As shown, a flue gas filtering device with a sonic soot blower provided by the present invention is provided, wherein a plurality of meshing teeth 7 are fixedly connected in an annular manner to a filter screen 9, a push block 8 is fixedly connected to the central tube 11, and the push block 8 is embedded between the meshing teeth 7 on the filter screen 9.

[0050] In this embodiment, when the driving rod 41 is not retracted, the push block 8 is in contact with the meshing teeth 7. When the center tube 11 rotates, the center tube 11 drives the push block 8 to rotate, and the push block 8 pushes the meshing teeth 7 on one side thereof. Under the thrust of the push block 8, the meshing teeth 7 drives the filter screen 9 to move horizontally, and the filter screen 9 drives the sliding sleeve 2 to which it is fixed to slide along the inner wall of the outer sleeve 1. Under the elastic limiting action of the No. 1 spring 43, as the center tube 11 continues to rotate, the push block 8 pushes all the filter screens 9 to vibrate horizontally at the same time, further preventing the filter screens 9 from being blocked.

[0051] like Figure 3 As shown, a flue gas filtering device with a sonic soot blower provided by the present invention is provided, and each guide sleeve 12 is provided with a plurality of air guide holes 13 , the air guide holes 13 are all strip-shaped, and all the air guide holes 13 are arranged along the generatrix direction of the guide sleeve 12 .

[0052] In this embodiment, the plurality of air guide holes 13 can increase the flow effect of the guide sleeve 12 .

[0053] Working principle:

[0054] The fixing flange 3 is fixedly connected to the flue gas pipe by bolts. At this time, the flue gas enters from one end of the outer sleeve 1, and each filter screen 9 filters the flue gas in turn. During this process, the central tube 11 is connected to the external water pump, and the external water pump introduces water into the central tube 11. The water flow in the central tube 11 is sprayed outward through the rotating rod 62 on the sliding seat 61, so as to spray and cool the flue gas; during this process, the guide sleeves 12 on one side of all sliding seats 61 guide the flue gas and perform contact cooling;

[0055] Furthermore, the motor 51 drives the driving wheel 52 to rotate, and the driving wheel 52 drives the central tube 11 to rotate by meshing with the driven wheel 53, and the central tube 11 drives all the sliding seats 61 to rotate, thereby increasing the spraying range of the sliding seats 61 and the contact degree between the smoke and the water vapor. At the same time, the sliding seats 61 can absorb the heat on the surface of the guide sleeve 12 through the sprayed water vapor, thereby improving the cooling effect on the surface of the guide sleeve 12. The guide sleeve 12 is conical, so that the guide sleeve 12 can quickly gather the water vapor after absorbing heat and guide it downward;

[0056] The central tube 11 drives all the guide sleeves 12 to rotate, and the air guide holes 13 on the guide sleeves 12 evenly disperse the smoke to various areas of the next filter screen 9, so as to prevent the smoke from concentrating in a certain area of ​​the filter screen 9 and causing partial blockage of the filter screen 9, thereby reducing the filtering effect of the filter screen 9;

[0057] Further, the driving rod 41 contracts, and the driving rod 41 squeezes the No. 1 spring 43 through the baffle 44. At this time, the No. 1 spring 43 pushes the sliding sleeve 2 to slide along the inner wall of the outer sleeve 1, and the sliding sleeve 2 drives all the filter screens 9 to squeeze all the No. 2 springs 14. Under the squeezing action of the No. 2 springs 14, the cooling mechanism 6 horizontally approaches the filter screen 9 and the guide sleeve 12. This process can increase the spraying uniformity of the cooling mechanism 6 on the filter screen 9 and the guide sleeve 12, and avoid the filter screen 9 being partially overheated and causing the surface of the filter screen 9 to melt;

[0058] Since the guide sleeve 12 is conical, after the driving rod 41 contracts to a certain extent, the cooling mechanism 6 approaches the surface of the filter screen 9 under the extrusion of the guide sleeve 12. At this time, the cooling mechanism 6 rotates with the central tube 11, and the cooling mechanism 6 can spray the surface of the filter screen 9 closely, thereby increasing the cleaning effect of the surface of the filter screen 9 and cooling the surface of the filter screen 9, further preventing the filter screen 9 from melting due to heat. At the same time, the brush 63 cleans the surface of the filter screen 9 to prevent the surface of the filter screen 9 from being blocked.

[0059] When the driving rod 41 is not retracted, the push block 8 is in contact with the meshing teeth 7. When the center tube 11 rotates, the center tube 11 drives the push block 8 to rotate, and the push block 8 pushes the meshing teeth 7 on one side thereof. Under the thrust of the push block 8, the meshing teeth 7 drives the filter screen 9 to move horizontally, and the filter screen 9 drives the sliding sleeve 2 to which it is fixed to slide along the inner wall of the outer sleeve 1. Under the elastic limiting action of the No. 1 spring 43, as the center tube 11 continues to rotate, the push block 8 pushes all the filter screens 9 to vibrate horizontally at the same time to avoid clogging of the filter screens 9.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
