Description

Technical Field

[0001] This utility model relates to the field of dust collector filter bag technology, specifically a dust collector filter bag for heating boilers. Background Technology

[0002] Heating boilers are core equipment that generate heat by burning fuels (such as coal, biomass pellets, or natural gas) to heat water, thereby providing heating and hot water to buildings. During their operation, fuel combustion produces flue gas containing a large amount of dust particles, which would seriously pollute the environment if directly emitted. Dust filter bags are a type of high-efficiency bag filter device, usually installed at the end of the boiler flue. Their interior is made of high-temperature resistant fiber material. When flue gas passes through, the filter bags can physically intercept and capture most of the dust particles, purifying the smoke and significantly reducing particulate matter emissions. They are a key component in ensuring that heating systems meet environmental protection standards.

[0003] The flue gas generated during the operation of heating boilers has a complex composition, containing not only dust but also acidic gases such as sulfur dioxide, as well as tar and odorous substances produced by incomplete combustion. However, existing dust collector filter bags typically only have physical filtration capabilities, effectively intercepting particulate matter but failing to treat these gaseous and sticky pollutants. Direct emissions of acidic gases exacerbate air pollution, while the release of tar and odorous substances causes environmental pollution and sensory discomfort, resulting in significant limitations in overall treatment effectiveness. Therefore, we propose a dust collector filter bag for heating boilers. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4A dust collector filter bag for heating boilers includes a dust collector filter bag body 1, an installation bag cylinder 2 fixedly installed on the right side of the dust collector filter bag body 1, an installation flange 4 installed on the right side of the installation bag cylinder 2, a first clamping arm 3 installed above the installation bag cylinder 2, a second clamping arm 6 installed below the installation bag cylinder 2, an installation bolt 5 threadedly installed at the front end of the first clamping arm 3, an activated carbon fiber layer 9 fixedly installed on the inner wall of the dust collector filter bag body 1; the activated carbon fiber layer 9 is made of activated carbon fiber felt material and has a cylindrical structure; an installation ring 8 is installed inside the installation flange 4, the outer surface of the installation ring 8 is provided with installation threads 12, a limestone block 7 is fixedly installed inside the installation ring 8, and the limestone block 7 has several honeycomb holes 14 inside; a limiting pressure block 10 is integrally fixedly installed on the inner wall of the first clamping arm 3.

[0026] In this implementation scheme: an activated carbon fiber layer 9 is installed inside the dust collector filter bag body 1. Activated carbon has a huge specific surface area and abundant micropores, which can efficiently adsorb tar components, unburned hydrocarbons and odor molecules in flue gas. At the same time, limestone blocks 7 are placed inside the mounting flange 4. The alkaline limestone blocks 7 react with acidic gases such as SO2 and HCl in the flue gas to generate solid salts. These solid salts are captured by the filter bag itself, thereby achieving the purpose of deacidification.

[0027] Furthermore:

[0028] In an alternative embodiment, the mounting ring 8 is threadedly connected to the mounting flange 4 via mounting thread 12.

[0029] In this implementation plan, the above-mentioned technology makes the installation and removal of the mounting ring 8 simple and convenient, so as to facilitate the replacement of the failed limestone block 7.

[0030] Furthermore:

[0031] In an optional embodiment, the honeycomb holes 14 penetrate the interior of the limestone block 7 and are uniformly distributed along the interior of the limestone block 7.

[0032] In this embodiment, the uniformly distributed honeycomb holes 14 increase the contact area between the flue gas and the limestone block 7, thereby improving the reaction effect between the limestone block 7 and the acidic gas.

[0033] Furthermore:

[0034] In an optional embodiment, the mounting ring 8 further includes:

[0035] The operating lever 13 is integrally fixedly installed on the right side of the mounting ring 8.

[0036] In this implementation scheme, the mounting ring 8 can be easily operated via the operating lever 13 to facilitate the installation and removal of the mounting ring 8.

[0037] Furthermore:

[0038] In an optional embodiment, the mounting flange 4 is further provided with:

[0039] The limiting groove 11 is formed on the outer surface of the mounting flange 4. The shape and size of the limiting groove 11 are larger than the shape and size of the limiting block 10. The inner diameter of the mounting bag 2 matches the local diameter of the mounting flange 4. The rear end of the first clamp arm 3 is hinged to the rear end of the second clamp arm 6. The front end of the first clamp arm 3 is bolted to the front end of the second clamp arm 6 through the mounting bolt 5. The mounting bag 2 is detachably connected to the mounting flange 4 through the first clamp arm 3 and the second clamp arm 6.

[0040] In this implementation scheme: the first clamp arm 3 and the second clamp arm 6 are limited by the cooperation of the limiting pressure groove 11 and the limiting pressure block 10, so as to prevent the first clamp arm 3 and the second clamp arm 6 from moving, and at the same time make the installation bag tube 2 and the installation flange 4 more secure.

[0041] Working principle: When using this dust collector filter bag for heating boilers, firstly, the installation bag sleeve 2 is fitted onto the installation flange 4. Then, the first clamp arm 3 and the second clamp arm 6 are fitted onto the installation bag sleeve 2, so that the limiting pressure block 10 is located inside the limiting pressure groove 11. Then, the first clamp arm 3 and the second clamp arm 6 are fixed together by the installation bolts 5. Next, the dust collector filter bag body 1 and the installation bag sleeve 2 are installed onto the installation flange 4. Next, the operating rod 13 is pinched to install the installation ring 8 into the installation flange 4 through the installation thread 12, thereby realizing the installation of the limestone block 7 into the installation flange 4. Then, the dust collector filter bag body 1 is installed onto the flue gas duct of the heating boiler through the installation flange 4. When the flue gas enters from the installation flange 4... Inside the installation bag cylinder 2 and the dust collector filter bag body 1, when the flue gas passes through the limestone block 7, it passes through the honeycomb pores 14. The acidic gases such as SO2 and HCl in the flue gas undergo a neutralization reaction to generate solid salts. These solid salts are captured by the dust collector filter bag body 1 itself, thereby achieving the purpose of deacidification. Then, when the flue gas passes through the activated carbon fiber layer 9, it efficiently adsorbs the tar components, unburned hydrocarbons, and odor molecules in the flue gas. The filtered flue gas is discharged through the dust collector filter bag body 1. Finally, when the dust collector filter bag body 1 is damaged, it can be removed from the installation flange 4 and replaced. Similarly, when the limestone block 7 is overused, the installation ring 8 can be removed and replaced. This is the working principle of the dust collector filter bag for the heating boiler.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
