Description

Technical Field

[0001] This utility model belongs to the field of flue gas filtration technology, specifically relating to a flue gas filtration device based on boiler AI automatic combustion. Background Technology

[0002] In industrial production, boilers that utilize AI-automated combustion are now an important source of heat energy. The flue gas produced by these boilers contains a large amount of harmful substances such as sulfides. The emission of these substances causes serious environmental pollution. In order to reduce the impact on the environment, traditional flue gas treatment technology usually adopts the spray scrubbing method, which uses a spray solution to chemically react with the sulfides in the flue gas to achieve the purpose of purifying the flue gas.

[0003] However, existing spray scrubbing devices have some shortcomings. First, these devices are usually designed with a fixed-size filter space, which cannot be adjusted according to the actual concentration of flue gas. When the flue gas concentration is low, the fixed-size filter space will lead to excessive use of spray solution, resulting in unnecessary waste. At the same time, the reduced efficiency of the solution contacting the flue gas also affects the filtration effect. On the other hand, when the flue gas concentration is high, the fixed-size filter space may not be able to provide sufficient contact area, resulting in insufficient filtration and failure to meet environmental emission standards.

[0004] To address the aforementioned issues, this invention proposes a flue gas filtration device based on AI-assisted automatic combustion in boilers. Utility Model Content

[0005] The purpose of this invention is to provide a flue gas filtration device based on boiler AI automatic combustion, which can more flexibly and efficiently meet the flue gas treatment needs under different operating conditions and flue gas concentrations.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A flue gas filtration device for automatic combustion of boilers based on AI includes a boiler body. The top of the boiler body is connected to a flue gas filtration chamber via a guide pipe. A pre-filter plate is provided inside the flue gas filtration chamber on the side near the guide pipe. A filter sheet is installed inside the flue gas filtration chamber on the side of the pre-filter plate away from the guide pipe. A sulfide filtration chamber is provided inside the flue gas filtration chamber and between the pre-filter plate and the filter sheet.

[0008] A spray body is provided at the top of the sulfide filter chamber. Spatial compression blocks are slidably connected to both sides of the flue gas filter chamber at corresponding positions. The spatial compression blocks are in contact with the bottom surface of the inner side of the flue gas filter chamber and the bottom of the spray body. A driving mechanism is installed between the flue gas filter chamber and the spatial compression blocks. The driving mechanism is used to drive the two spatial compression blocks to move in opposite directions.

[0009] The driving mechanism includes connecting plates fixed on both sides of the flue gas filter chamber. A bidirectional threaded rod and a limiting rod are mounted between the two connecting plates. Both the bidirectional threaded rod and the limiting rod are located at the top of the flue gas filter chamber. The bidirectional threaded rod is rotatably connected to the two connecting plates, and the limiting rod is slidably connected to the space compression block. The two ends of the outer side of the bidirectional threaded rod are threadedly connected to the two space compression blocks respectively. The threads at the two ends of the bidirectional threaded rod have opposite directions. A motor is mounted on the outer side of one of the connecting plates, and the output end of the motor is connected to the bidirectional threaded rod.

[0010] An inclined surface is provided on the bottom surface of the inner side of the flue gas filter chamber and at the location of the sulfide filter chamber. A solution collection chamber is also installed inside the flue gas filter chamber and at the inclined lower end of the inclined surface.

[0011] The space compression blocks located inside the sulfide filter chamber each have curved surfaces at their ends that are close to each other.

[0012] A soft pad is provided on the top of the spatial compression block and between the spatial compression block and the flue gas filter chamber.

[0013] A baffle plate is fixed to the bottom surface of the flue gas filtration chamber and to the side of the solution collection chamber away from the inclined surface.

[0014] The technical effects achieved by this utility model are as follows:

[0015] This invention can automatically adjust the size of the filtration space according to the concentration of flue gas. When the flue gas concentration is low, the filtration space will shrink accordingly, reducing the amount of spray solution used, while ensuring the contact effect between the flue gas and the solution, thereby improving filtration efficiency and reducing resource waste. Conversely, when the flue gas concentration is high, the filtration space will increase to ensure sufficient contact area for effective flue gas purification. This invention can more flexibly and efficiently meet the flue gas treatment needs under different working conditions and flue gas concentrations. Attached Figure Description

Detailed Implementation

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figure 1-4 As shown, a flue gas filtration device for automatic combustion of boilers based on AI includes a boiler body 1. The top of the boiler body 1 is connected to a flue gas filtration chamber 3 via a guide pipe 2. After the materials inside the boiler body 1 are burned, the exhaust gas generated by the combustion is transported to the interior of the flue gas filtration chamber 3 through the guide pipe 2. The exhaust gas is filtered by the objects inside the flue gas filtration chamber 3. A pre-filter plate 5 is provided on the side of the flue gas filtration chamber 3 near the guide pipe 2. When the flue gas passes through the pre-filter plate 5, it undergoes a pre-filtration, which can filter out large molecules in the flue gas. The pre-filter plate 5 can be made of glass fiber, polyester fiber, etc. These materials can effectively remove larger particles, such as dust and pollutants, reducing the burden on subsequent filtration stages.

[0024] Inside the flue gas filtration chamber 3, on the side of the pre-filter plate 5 away from the guide pipe 2, a filter 7 is installed. This filter 7 is used to filter small particles in the flue gas and is the final purification filter. The filter 7 can be activated carbon, HEPA filter, electrostatic filter material, etc. These materials can remove even smaller particles and harmful gases, ensuring that the final emission gas meets environmental protection standards. Inside the flue gas filtration chamber 3, between the pre-filter plate 5 and the filter 7, a sulfide filter chamber 6 is set up. This sulfide filter chamber 6 can filter sulfides such as sulfur dioxide generated in the flue gas.

[0025] See attached document Figure 3 As shown, the specific filtration method is as follows: A spray body 13 is installed at the top of the sulfide filter chamber 6. The spray body 13 can spray solutions such as nitric acid and sodium hydroxide that can combine with sulfur to form water-soluble salts, thereby removing sulfur. The sulfur-removed flue gas continues to travel until it passes through the filter plate 7 and is then discharged through the outlet pipe 14. (Refer to the attached diagram.) Figure 3 An inclined surface 15 is provided on the bottom surface of the inner side of the flue gas filter chamber 3, at the position of the sulfide filter chamber 6. The inclined surface 15 guides the solution falling into the inner side of the flue gas filter chamber 3. A solution collection chamber 16 is also installed inside the flue gas filter chamber 3 at the inclined lower end of the inclined surface 15. The solution is guided into the solution collection chamber 16 and then processed through the solution collection chamber 16. A baffle plate 17 is fixed on the bottom surface of the inside of the flue gas filter chamber 3 on the side of the solution collection chamber 16 away from the inclined surface 15. The baffle plate 17 can block the solution and prevent the solution from flowing to other positions when the solution collection chamber 16 cannot collect the solution in time.

[0026] Space compression blocks 8 are slidably connected to both sides of the flue gas filter chamber 3 at positions corresponding to those of the sulfide filter chamber 6, see Appendix. Figure 4As shown, the space compression blocks 8 located inside the sulfide filter chamber 6 are all provided with curved surfaces 4 at their respective ends facing each other. The curved surfaces 4 create a curved space inside the sulfide filter chamber 6, thereby slowing down the flue gas and ensuring sufficient contact time between the solution and the flue gas. The space compression blocks 8 are in contact with the bottom surface of the inner side of the flue gas filter chamber 3 and the bottom of the spray body 13. Soft pads are provided on the top of the space compression blocks 8 and between the space compression blocks 8 and the flue gas filter chamber 3. The space compression block 8 is configured to seal with the flue gas filter chamber 3 when it moves. The soft pad on the top of the space compression block 8 can seal the spray holes of the spray body 13 that come into contact with the space compression block 8. The soft pad can be made of rubber, silicone, etc. The bottom of the space compression block 8 is inclined so that it can cooperate with the inclined surface 15 and will not get stuck. A drive mechanism is installed between the flue gas filter chamber 3 and the space compression block 8. The drive mechanism is used to drive the two space compression blocks 8 to move in opposite directions.

[0027] The two space compression blocks 8 are driven by a drive mechanism to move towards each other. As the space compression blocks 8 move, they compress the space inside the sulfide filter chamber 6 and block the spray holes at the spray body 13. This causes the space inside the sulfide filter chamber 6 to shrink when the space compression blocks 8 move towards each other. When there is less flue gas, the two space compression blocks 8 can be moved towards each other to reduce the internal space of the sulfide filter chamber 6 and block the spray holes at both ends of the spray body 13. This arrangement can minimize the waste of the solution sprayed at the spray body 13, allowing the flue gas to come into contact with the solution as much as possible. A sensor can be installed in the guide tube 2 to detect the flue gas concentration. This sensor can be a flue gas concentration sensor or a sensor that can reduce the concentration of flue gas. The drive mechanism is activated by a controller.

[0028] See attached document Figure 2 The drive mechanism includes connecting pieces 9 fixed on both sides of the flue gas filter chamber 3. A bidirectional threaded rod 10 and a limiting rod 11 are mounted between the two connecting pieces 9. The bidirectional threaded rod 10 and the limiting rod 11 are both located on the top of the flue gas filter chamber 3. The bidirectional threaded rod 10 is rotatably connected to the two connecting pieces 9, and the limiting rod 11 is slidably connected to the space compression block 8. The two ends of the outer side of the bidirectional threaded rod 10 are threadedly connected to the two space compression blocks 8 respectively. The threads at the two ends of the bidirectional threaded rod 10 are in opposite directions. A motor 12 is mounted on the outer side of one of the connecting pieces 9. The output end of the motor 12 is connected to the bidirectional threaded rod 10.

[0029] When driven by motor 12, it can drive the bidirectional threaded rod 10 to rotate, and then the two space compression blocks 8 are connected by threads on the outer sides of both ends of the bidirectional threaded rod 10. This allows the space compression blocks 8 to move in opposite directions, thereby enabling the two space compression blocks 8 to expand and shrink the space inside the sulfide filter chamber 6.

[0030] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
