Description

Technical Field

[0001] The utility model relates to the technical field of boiler flue gas exhaust, in particular to a soot cleaning structure for a boiler flue gas filtration device. Background Technique

[0002] A boiler is an energy conversion device. The energy input into the boiler includes chemical energy in fuel and electric energy. The boiler outputs steam, high-temperature water or organic heat carriers with a certain amount of heat energy. The original meaning of "pot" refers to a water container heated on fire, and "furnace" refers to a place for burning fuel. The boiler includes two major parts: the pot and the furnace. The hot water or steam generated in the boiler can directly provide the required heat energy for industrial production and people's livelihood, or can be converted into mechanical energy through a steam power device, or further converted into electric energy through a generator. A boiler that provides hot water is called a hot water boiler, which is mainly used for life and has a small amount of application in industrial production. A boiler that generates steam is called a steam boiler, often simply referred to as a boiler, and is mostly used in thermal power plants, ships, locomotives and industrial and mining enterprises. At present, during the use of boilers, carbon-based materials need to be burned for heating, and the generated gas is directly discharged into the air through the exhaust port. However, the air generated by burning contains a large amount of dust. Direct discharge into the air will cause serious pollution. Although existing equipment can filter soot, the filter screen used for filtration will be affected by blockage of particulate matter in the soot in the long term, and the installation of the filter screen is extremely complex and cannot be quickly removed for cleaning, resulting in backflow during soot discharge and increasing the severity of pollution.

[0006] As a preferred solution, a limiting spring is fixedly installed at the end of the inner cavity of the installation groove, and the inner end of the limiting spring is connected to the outer end of the installation block.

Detailed implementation mode

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0019] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present utility model. The "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that excludes other embodiments.

[0020] Embodiment 1:

[0021] Please refer to Figure 1 As shown, the present utility model provides a soot cleaning structure for a boiler flue gas filtering device, including a smoke inlet pipe 1. The upper end of the smoke inlet pipe 1 is connected and installed with a filtering box 2. The bottom of the filtering box 2 is hermetically installed with a mounting bottom plate 3. The upper end of the smoke inlet pipe 1 penetrates through the mounting bottom plate 3 and extends to the outside. The right side of the top of the filtering box 2 is connected with a smoke exhaust pipe 6. Both sides of the inner cavity of the filtering box 2 are fixedly installed with fixing seats 7. An installation groove 8 is opened inside the fixing seat 7. Both ends of the inner cavity of the installation groove 8 are slidably installed with installation blocks 9. A clamping convex block 11 is clamped and installed inside the installation block 9 and located in the installation groove 8. The top of the clamping convex block 11 is fixedly installed with a soot filtering plate 12. An activated carbon filter net 13 is arranged at the bottom of the soot filtering plate 12.

[0022] With the application of the installation block 9, the clamping convex block 11, the soot filtering plate 12 and the activated carbon filter net 13 in this technical solution, after the soot discharged from the boiler is filtered in stages, since the soot contains a large amount of dust particles and is easy to adsorb on the surfaces of the soot filtering plate 12 and the activated carbon filter net 13, it will cause blockage over time. Inside the filtering box 2, the bottom of the soot filtering plate 12 is installed by clamping, so that the soot filtering plate 12 and the activated carbon filter net 13 can be quickly removed in the later stage to clean the blockage on their surfaces.

[0023] Embodiment 2:

[0024] On the basis of Embodiment 1, as shown in the present utility model Figure 2 A sealing ring 4 is sleeved outside the upper end of the smoke inlet pipe 1 at the bottom of the mounting bottom plate 3, and the top of the sealing ring 4 is connected to the bottom of the mounting bottom plate 3.

[0025] Adopt asFigure 1 In the technical solution shown, the sealing ring 4 can seal and reinforce the penetration connection part between the upper end of the smoke inlet pipe 1 and the filter box 2 and the mounting base plate 3, avoiding gap leakage during smoke exhaust.

[0026] Secondly, in the technical solution, a limit spring 10 is fixedly installed at the end of the inner cavity of the installation groove 8, and the inner end of the limit spring 10 is connected to the outer end of the installation block 9; bending reinforcement plates 5 are welded and installed on both sides of the upper end of the filter box 2, and installation holes are formed on the surface of the lower end of the bending reinforcement plates 5.

[0027] It adopts the technical solution as Figure 1 shown. The limit spring 10 can squeeze and support one end of the installation block 9 and adjust the clamping distance between the two installation blocks 9, so as to squeeze and fix the end of the clamping convex block 11 and ensure the firmness of the soot filter plate 12 after being installed inside the filter box 2.

[0028] Embodiment 3:

[0029] As shown in the present utility model Figures 1-4 shown, a lapping plate is fixedly installed at the bottom of the fixed seat 7, and the inner end of the lapping plate extends into the filter box 2 and is connected to the bottom of the activated carbon filter net 13; the top of the filter box 2 is installed with a sealing top cover through the cooperation of screws and gaskets, and the sealing top cover is hermetically connected to the penetration part at the lower end of the smoke exhaust pipe 6.

[0030] Adopting the above technical solution, a part of the lapping plate connected to the bottom of the fixed seat 7 extends out, and in addition, the card slot formed at the top can cooperate with the convex block at the bottom of the activated carbon filter net 13, which can quickly complete the installation of the activated carbon filter net 13, and has high firmness and is easy to disassemble in the later stage. The sealing top cover at the top of the filter box 2 can be manually removed to remove and clean the internal filtering structure.

[0031] The working principle of the present utility model is as follows: connect the lower end of the smoke inlet pipe 1 to the smoke exhaust port of the boiler, and install the outside of the filter box 2 on one side of the wall through the mounting base plate 3 and the bending reinforcement plate 5. The flue gas enters the inside of the filter box 2 from the smoke inlet pipe 1, and the dust particles and odor gas in the flue gas are filtered by the activated carbon filter net 13 and the soot filter plate 12. Since during long-term filtration, the particles in the soot will adsorb on the surfaces of the activated carbon filter net 13 and the soot filter plate 12 and cause blockage. At this time, use tools to remove the sealing top cover, and the soot filter plate 12 and the activated carbon filter net 13 can be quickly removed from the inside of the filter box 2 manually and cleaned or replaced to avoid blockage of the filter mesh holes and affect the soot filtration and emission efficiency.
