Description

Technical Field

[0001] This utility model belongs to the field of cyclone separator technology, specifically relating to a wear-resistant liner for the target area of ​​a cyclone separator in a circulating fluidized bed boiler. Background Technology

[0002] A cyclone separator for circulating fluidized bed boilers is a highly efficient gas-solid separation device, typically located at the boiler furnace outlet. It captures solid particles (such as bed material and fly ash) from the flue gas and returns them to the furnace to maintain combustion efficiency and ensure continuous combustion. Its working principle is based on the interaction of centrifugal force and gravity. Dust-laden flue gas enters the separator tangentially and rotates at high speed. Particles are thrown against the wall due to inertia and separated, while clean gas exits from the center. This equipment features simple structure, high separation efficiency, and resistance to high temperatures and wear. It is a key component in circulating fluidized bed boilers for achieving material circulation and low emissions, directly affecting the boiler's combustion stability and environmental performance.

[0003] The wear-resistant lining used in the target area of ​​the cyclone separator in a circulating fluidized bed boiler is generally installed on the inner wall of the cyclone separator inlet to prevent the inner wall from being easily eroded by high concentrations of particles. However, the replacement of traditional castable or brick linings requires crushing and dismantling, which is time-consuming and reduces the frequency of wear-resistant lining replacements. Utility Model Content

Detailed Implementation

[0014] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0016] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0017] Example Reference Figure 1-5 This embodiment of the present invention provides a wear-resistant liner for the target area of ​​a cyclone separator in a circulating fluidized bed boiler, comprising: The separation mechanism 100 includes a rotary separator body 110, an air outlet pipe 120 connected to the top of the rotary separator body 110, an air inlet pipe 130 connected to the surface of the rotary separator body 110, and an inner liner body 140 disposed inside the inner liner body 140 for protecting the inner wall of the air inlet pipe 130. The replacement mechanism 200 includes a modular replacement component 210 for quick modular disassembly and assembly of the inner liner body 140, and an overall replacement component 220 for overall replacement of the inner liner body 140.

[0018] The modular replacement component 210 and the overall replacement component 220 work together to quickly replace the inner lining body 140 as a whole or in individual pieces. This solves the problem of low replacement efficiency caused by the traditional method of breaking and dismantling the inner lining body 140, which is time-consuming, and improves the replacement efficiency of the inner lining body 140.

[0019] Specifically, the modular replacement component 210 includes an installation cylinder 211 disposed inside the air intake pipe 130, several limiting strips 212 fixedly installed on the inner wall of the installation cylinder 211 for limiting the installation of the inner liner body 140, several stops 213 fixedly installed at the end of the installation cylinder 211 for limiting the installation of the inner liner body 140, and snap-fit ​​components 214 for limiting the installation of the inner liner body 140.

[0020] It should be noted that the dimensions of the rotary separator body 110 need to be adapted to the dimensions of the boiler in order to avoid affecting the boiler's performance in various aspects.

[0021] Furthermore, the snap-fit ​​component 214 includes several grooves formed at the end of the mounting cylinder 211, a rotating shaft 2141 rotatably mounted inside the grooves, a snap plate 2142 fixedly mounted at the end of the rotating shaft 2141 and used to limit the inner liner body 140, and a rotating piece 2143 fixedly mounted on the surface of the snap plate 2142.

[0022] The mechanism, through the cooperation between the rotating shaft 2141 and the clamping plate 2142, is used to clamp and limit the modular inner lining body 140, making it easy to disassemble and replace, and improving the replacement efficiency of a single inner lining body 140.

[0023] Preferably, a spring 2144 is fixedly installed on the surface of the card plate 2142, and a limit ring 2145 is fixedly installed on the other end of the spring 2144, with one side of the limit ring 2145 contacting the inner wall of the groove.

[0024] The spring 2144 and the limiting ring 2145 work together to limit the rotation of the clamping plate 2142, so as to keep the clamping plate 2142 in a state of being engaged or disengaged from the inner lining body 140, so as to facilitate the replacement of the inner lining body 140.

[0025] Furthermore, the overall replacement component 220 includes an internally threaded cylinder 221 fixedly installed inside the intake pipe 130, and a raised thread 222 provided on the surface of the mounting cylinder 211. Mounting cylinder 211 is threaded into the interior of internally threaded cylinder 221 via raised thread 222.

[0026] The engagement between the internal threaded cylinder 221 and the raised thread 222 facilitates the disassembly and assembly of the mounting cylinder 211, thereby making it easier to disassemble and assemble the entire inner liner body 140 and improving the efficiency of its overall replacement.

[0027] Furthermore, a locking block 223 for limiting the installation of the mounting cylinder 211 is fixedly installed on the surface of the mounting cylinder 211, and a rotating handle 224 for easy rotation and disassembly is fixedly installed on the surface of the mounting cylinder 211.

[0028] The locking block 223 is used to limit the installation of the mounting cylinder 211, thereby improving the installation positioning of the mounting cylinder 211. The rotating handle 224 is used to facilitate the rotation of the mounting cylinder 211, making it easy to install and remove it from the inside of the internal threaded cylinder 221.

[0029] When it is necessary to replace a single inner lining body 140 during use, the rotating plate 2143 rotates the clamping plate 2142, causing the clamping plate 2142 to detach from the surface of the inner lining body 140. Then, the inner lining body 140 is pulled out from between the limiting strips 212, and the new inner lining body 140 is inserted between the limiting strips 212 until one side of the inner lining body 140 abuts against the stop block 213. At this time, the clamping plate 2142 is rotated again, so that the end of the clamping plate 2142 rotates to one side of the inner lining body 140 to clamp the inner lining body 140, thus completing the quick replacement of a single inner lining body 140. When the entire inner liner body 140 needs to be replaced, the mounting cylinder 211 needs to be rotated by turning the handle 224, so that the mounting cylinder 211 gradually exits the interior of the internal thread cylinder 221 until the mounting cylinder 211 is completely removed from the interior of the internal thread cylinder 221, thereby disassembling the entire inner liner body 140. Then, the mounting cylinder 211 with the new inner liner body 140 is installed inside the internal thread cylinder 221. Under the action of the protruding thread 222, the mounting cylinder 211 is threaded into the interior of the internal thread cylinder 221 until the locking block 223 is engaged at the opening end of the air intake pipe 130, thus completing the replacement of the entire inner liner body 140.

[0030] In summary, the modular replacement component 210 and the integral replacement component 220 work together to quickly replace the inner lining body 140 as a whole or in individual pieces. This solves the problem of low replacement efficiency caused by the traditional method of breaking and dismantling the inner lining body 140, which is time-consuming, and improves the replacement efficiency of the inner lining body 140.
