Description

Technical Field

[0001] This application relates to the technical field of purification and treatment devices, and in particular to a combined purification and treatment device for biomass boiler flue gas. Background Technology

[0002] Biomass boilers are a type of boiler that uses biomass energy as fuel. They are classified into biomass steam boilers, biomass hot water boilers, biomass hot air furnaces, biomass thermal oil furnaces, vertical biomass boilers, and horizontal biomass boilers. When biomass boilers are in use, they often produce a large amount of high-temperature flue gas. In order to avoid pollution of the surrounding environment by the high-temperature flue gas, purification treatment devices are often needed to purify the high-temperature flue gas produced by biomass boilers.

[0003] When in use, the relevant purification and treatment device usually connects the biomass boiler to a sealed container through a pipeline. The high-temperature flue gas generated by the biomass boiler is then introduced into the sealed container through the pipeline. The toxic and harmful substances in the high-temperature flue gas are then filtered and absorbed by the graphite or activated carbon plates in the container before being discharged, thereby achieving the effect of purifying the high-temperature flue gas.

[0004] However, when using the above-mentioned methods, the high-temperature flue gas often passes through the graphite or activated carbon plates at normal pressure during filtration and purification. This process is often slow and requires a significant amount of time to purify the high-temperature flue gas, resulting in low efficiency and poor purification effect. Therefore, those skilled in the art have provided a combined purification and treatment device for biomass boiler flue gas to solve the problems mentioned in the background art.

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses a combined purification and treatment device for flue gas from a biomass boiler. (Refer to...) Figure 2 Figure 3 A combined purification and treatment device for flue gas from a biomass boiler includes a purification tank 1, with an inspection door 102 installed on the side wall of the purification tank 1. Several support legs 101 are fixedly connected to the bottom of the purification tank 1. Air inlet and outlet mechanisms 2 for air intake and exhaust are provided at both ends of the purification tank 1.

[0024] The pressurized filtration mechanism 3 is located on the inner wall of the purification tank 1 to compress and pressurize the high-temperature flue gas for rapid filtration and purification.

[0025] The pressurized filtration mechanism 3 includes a filtration pool 301 and a filtration assembly 4. The filtration pool 301 is fixedly connected to the bottom inner side of the purification tank 1, and the filtration assembly 4 is installed on the top of the filtration pool 301.

[0026] The filter assembly 4 includes a movable frame 401, an activated carbon plate 402, and a compression unit 5. The side wall of the movable frame 401 is installed on the top of the filter tank 301 through the compression unit 5, and the side wall of the activated carbon plate 402 is installed in the middle of the movable frame 401 through a convenient insertion mechanism 6.

[0027] The compression unit 5 includes two support slide rods 501 and two electric push rods 502. One end of the two support slide rods 501 is symmetrically fixed to the top of the water filter tank 301. The two electric push rods 502 are symmetrically fixed to the inner side of the top of the water filter tank 301. The side wall of the movable frame 401 is slidably connected to the side wall of the two support slide rods 501, and the output end of the two electric push rods 502 is fixedly connected to the bottom of the movable frame 401.

[0028] The air inlet / outlet mechanism 2 includes an air outlet pipe 201, an air outlet valve 202, an air inlet pipe 203, and an air inlet valve 204. One end of the air outlet pipe 201 is fixedly connected to the top of the purification tank 1, the air outlet valve 202 is fixedly connected to the side wall of the air outlet pipe 201, one end of the air inlet pipe 203 is fixedly connected to the bottom of the filter water tank 301 through the bottom of the purification tank 1, and the air inlet valve 204 is fixedly connected to the side wall of the air inlet pipe 203.

[0029] In this embodiment, firstly, the purification tank 1 is erected in the usage area using the support legs 101. Then, by opening the maintenance door 102, which is hinged or snap-fitted on one side, the activated carbon plate 402 is easily installed into the middle of the movable frame 401 via the convenient insertion mechanism 6. Next, the purification tank 1 is connected to the biomass boiler via the air inlet pipe 203. The air inlet valve 204 is opened to open the air inlet pipe 203, allowing the high-temperature flue gas generated by the biomass boiler to be transported through the inlet pipe 203 to the filter water tank 301 at the bottom of the purification tank 1. The water in the filter water tank 301 initially filters and adsorbs the ash and slag in the high-temperature flue gas, while the water-insoluble flue gas rises from the water surface and enters the upper part of the purification tank 1. Then, the activated carbon plate 402 is installed in the middle of the movable frame 401 via the convenient insertion mechanism 6. The activated carbon plate 402 filters, absorbs, and purifies the toxic and harmful substances in the flue gas. Simultaneously, two electric push rods 502, controlled by the same control system, retract, causing the connected movable frame 401 to slide downwards on the support slide rod 501. This downward movement of the movable frame 401 causes the activated carbon plate 402 to follow suit, shortening the distance between the activated carbon plate 402 and the water surface. This compresses the space between the activated carbon plate 402 and the water surface, pressurizing the flue gas and allowing it to be quickly filtered out through the filter holes of the activated carbon plate 402. The reciprocating up-and-down movement of the activated carbon plate 402 facilitates the compression and pressurization of the high-temperature flue gas, enabling it to quickly and thoroughly pass through the activated carbon plate 402 to filter, adsorb, and purify the toxic and harmful substances, effectively improving purification efficiency and effect.

[0030] Furthermore, after the high-temperature flue gas is purified, the exhaust valve 202 is opened to open the exhaust pipe 201. At this time, the purified flue gas can be discharged from the purification tank 1 and released into the surrounding environment through the opened exhaust pipe 201.

[0031] Furthermore, the convenient insertion mechanism 6 includes two telescopic slides 601, two springs 602, two limiting blocks 603, and two control rods 604. The two telescopic slides 601 are symmetrically opened on the inner wall of the movable frame 401. One end of each of the two limiting blocks 603 is elastically connected to one end of each of the two telescopic slides 601 by the two springs 602. The two control rods 604 slide through the top of the movable frame 401 and are fixedly connected to the top of each of the two limiting blocks 603.

[0032] The convenient insertion mechanism 6 also includes two limiting slots 7, which are symmetrically opened on the side wall of the activated carbon plate 402, and the two limiting slots 7 fit into the two limiting blocks 603.

[0033] When installing the activated carbon plate 402 based on the above embodiment, pulling the control rod 604 causes the connected limiting block 603 to slide and retract into the telescopic groove 601 on the inner wall of the moving frame 401. Then, the limiting groove 7 on the side wall of the activated carbon plate 402 is aligned with the limiting block 603, and the activated carbon plate 402 is embedded into the middle of the moving frame 401. By releasing the control rod 604, the spring 602 provides a reaction force, causing the limiting block 603 to spring back and slide out from the telescopic groove 601. 03. The spring-loaded sliding extension inserts into the corresponding limiting slot 7 to form a limiting engagement and fixation, thus completing the convenient engagement and fixation of the activated carbon plate 402. Similarly, by pulling the control lever 604, the limiting block 603 retracts and releases its engagement with the limiting slot 7, allowing the activated carbon plate 402 to be removed from the middle of the moving frame 401, thus completing the disassembly of the activated carbon plate 402. This facilitates the convenient installation and disassembly of the activated carbon plate 402, making it easier to maintain or replace the activated carbon plate 402 and ensuring its proper use for filtering and purifying flue gas.

[0034] The implementation principle of the combined purification and treatment device for biomass boiler flue gas in this application embodiment is as follows: In use, firstly, the purification tank 1 is erected in the usage area using the support leg 101. Then, the purification tank 1 is opened by opening the maintenance door 102, which is hinged or snap-fitted on one side. At this time, by pulling the control lever 604, the connected limiting block 603 is slidably retracted into the telescopic groove 601 on the inner wall of the moving frame 401. Then, the limiting groove 7 on the side wall of the activated carbon plate 402 is aligned with the limiting block 603, and the activated carbon plate 402 is embedded into the middle of the moving frame 401. By releasing the control lever 604 and using the reaction force provided by the spring 602, the limiting block 603 is forced to retract from the telescopic groove 601. The activated carbon plate 402 is easily secured by a spring-loaded sliding extension mechanism. The limiting block 603 springs back and slides out, inserting into the corresponding limiting slot 7 to form a locking and fixing mechanism. Similarly, pulling the control rod 604 retracts the limiting block 603, releasing it from the limiting slot 7, allowing the activated carbon plate 402 to be removed from the center of the moving frame 401. This facilitates the easy installation and removal of the activated carbon plate 402, enabling maintenance, repair, or replacement, and ensuring proper filtration and purification of flue gas. Furthermore, the purification tank 1 is connected to the biomass boiler via the air inlet pipe 203. The air inlet valve is then opened... 204. This opens the air inlet pipe 203, allowing the high-temperature flue gas from the biomass boiler to be transported through the inlet pipe 203 to the filter water tank 301 at the bottom of the purification tank 1. The water in the filter water tank 301 initially filters and adsorbs the ash and slag in the high-temperature flue gas, while the water-insoluble flue gas emerges from the water surface and enters the upper part of the purification tank 1. There, it passes through the activated carbon plate 402 to filter, absorb, and purify the toxic and harmful substances in the flue gas. Simultaneously, two electric push rods 502, controlled by the same control system, retract and drive the connected movable frame 401 to slide downward on the support slide rod 501. The downward movement of the movable frame 401 causes the activated carbon plate 402 to be subjected to force. As the activated carbon plate 402 moves downward, the distance between it and the water surface is shortened, thereby compressing the space between the activated carbon plate 402 and the water surface. This allows the flue gas to be pressurized in the compressed space and quickly filtered out through the filter holes of the activated carbon plate 402. The reciprocating up and down movement of the activated carbon plate 402 effectively compresses and pressurizes the high-temperature flue gas, allowing it to quickly and fully pass through the activated carbon plate 402 to filter, adsorb, and purify toxic and harmful substances, effectively improving purification efficiency and effect. Finally, after purification, the high-temperature flue gas is opened by opening the outlet valve 202, thereby opening the outlet pipe 201. At this time, the purified flue gas can be discharged from the purification tank 1 and released into the surrounding environment through the opened outlet pipe 201.

[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
