Description

Technical Field

[0001] This utility model relates to the field of dust treatment technology for activated carbon desulfurization towers, and specifically discloses a dust processor for activated carbon desulfurization towers. Background Technology

[0002] Activated carbon desulfurization towers are purification devices that use activated carbon to desulfurize industrial waste gas. During the process, the activated carbon desulfurization tower will generate smoke and dust, and the dust in the smoke and dust will pollute the environment, so it is necessary to filter the dust in the smoke and dust.

[0003] Chinese patent CN218130672U discloses a dust processor for activated carbon desulfurization towers. A rodless cylinder is installed inside the activated carbon desulfurization tower, and a sliding block is slidably installed inside the tower. A side-wall scraper ring contacts the inner wall of the tower. When the activated carbon desulfurization tower discharges flue gas, a first filter screen filters the dust in the flue gas to prevent dust from affecting the environment, and a second filter screen performs secondary filtration to improve the filtration effect. Simultaneously, the rodless cylinder can be controlled to move the sliding ring up and down, which in turn moves the annular frame, the first filter screen, and the second filter screen up and down, shaking off the dust from these screens. The annular frame also moves the side-wall scraper ring up and down, which scrapes away impurities from the inner wall of the activated carbon desulfurization tower. After the impurities on the inner wall of the activated carbon desulfurization tower are cleaned, the rodless cylinder is shut off.

[0004] The drawback of the aforementioned dust processor is that its cleaning method relies primarily on mechanical shaking and scraping, resulting in the dust being removed only from within the system—a cleaning-only, non-discharge model. Consequently, dust detached from the filter cannot be effectively collected and discharged from the system, eventually accumulating inside the device and requiring subsequent disassembly and cleaning. This not only increases maintenance frequency but also adds extra workload.

[0005] Therefore, a dust processor for activated carbon desulfurization towers is needed to solve the above problems. Utility Model Content

[0006] This invention proposes a dust processor for activated carbon desulfurization towers, which can conveniently clean and collect dust, thereby effectively reducing maintenance workload.

[0007] This utility model is implemented as follows: a dust processor for an activated carbon desulfurization tower includes an activated carbon desulfurization tower body, the outer wall of which is connected to a bend pipe, the bend pipe being composed of two horizontal sections and one vertical section, and metal sintered mesh being installed inside the two horizontal sections of the bend pipe. The bend is equipped with a back-flushing cleaning mechanism, which includes an L-shaped pipe. The two ends of the L-shaped pipe are located to the right of the two sintered metal meshes and are connected to the inside of the bend. A centrifugal fan with an air outlet connected to the inside of the L-shaped pipe is provided on the outside of the bend. A first electric butterfly valve is provided on each of the two horizontal sections of the bend, located on the opposite side of the two sintered metal meshes. A second electric butterfly valve is provided on the vertical section of the bend. The backflushing cleaning mechanism also includes two collection mechanisms, which are located on the left side of the corresponding metal sintered mesh. Each collection mechanism includes a discharge pipe connected to the horizontal section of the bend. A third electric butterfly valve is provided on the discharge pipe, and a detachable filter collection bag is provided below the discharge pipe.

[0008] As a preferred embodiment of the dust processor for activated carbon desulfurization tower of this utility model, the outer wall of the discharge pipe is fixedly connected to an internally threaded cylinder, the internal thread of the internally threaded cylinder is connected to a connection port, the lower end of the connection port is fixedly connected to an annular plate, the filter collection bag is fixedly connected to the lower end of the annular plate, and a sealing gasket that abuts against the upper edge of the connection port is embedded in the top of the inner wall of the internally threaded cylinder through a groove.

[0009] As a preferred dust processor for activated carbon desulfurization tower according to this utility model, the L-shaped pipe is equipped with a fourth electric butterfly valve at both ends.

[0010] As a preferred dust processor for activated carbon desulfurization towers according to this utility model, a reinforcing plate is fixedly connected between the activated carbon desulfurization tower body and the bend pipe.

[0011] As a preferred dust processor for activated carbon desulfurization towers according to this utility model, the outer wall of the reinforcing plate is equipped with an operation panel and a controller.

[0012] As a preferred dust processor for activated carbon desulfurization towers according to this utility model, a guide ring is fixedly connected between the inner wall of the filter collection bag and the lower end of the ring plate.

[0013] As a preferred dust processor for activated carbon desulfurization towers according to this utility model, a mounting frame is fixedly connected between the reinforcing plate and the bend, and the centrifugal fan is installed on the outer wall of the mounting frame.

[0014] The beneficial effects of this utility model are: Under normal filtration conditions, the first and second electric butterfly valves remain open, while the fourth and third electric butterfly valves are closed, allowing dust-laden exhaust gas to pass through the sintered metal mesh for filtration. When dust removal is required, the first and second electric butterfly valves are closed, while the fourth and third electric butterfly valves are opened simultaneously. Subsequently, the centrifugal fan is started, generating a reverse airflow that penetrates the sintered metal mesh, guiding the blown-off dust through the discharge pipe into a removable filter collection bag for collection. This design achieves automated dust cleaning and collection, thereby greatly reducing maintenance workload. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0019] Please see Figure 1-4 A dust processor for an activated carbon desulfurization tower includes an activated carbon desulfurization tower body 1, with a bend 2 connected to the outer wall of the activated carbon desulfurization tower body 1. The bend 2 consists of two horizontal sections and one vertical section, and a metal sintered mesh 3 is installed inside the two horizontal sections of the bend 2. The bend 2 is equipped with a back-flushing cleaning mechanism, which includes an L-shaped pipe 8. The two ports of the L-shaped pipe 8 are located to the right of the two metal sintered meshes 3 and are connected to the inside of the bend 2. The outside of the bend 2 is equipped with a centrifugal fan 7 whose air outlet is connected to the inside of the L-shaped pipe 8. The two horizontal sections of the bend 2 are each equipped with a first electric butterfly valve 4 located on the opposite side of the two metal sintered meshes 3, and the vertical section of the bend 2 is equipped with a second electric butterfly valve 5. The backflushing cleaning mechanism also includes two collection mechanisms, which are located on the left side of the corresponding metal sintered mesh 3. The collection mechanism includes a discharge pipe 10 connected to the horizontal section of the bend 2. A third electric butterfly valve 11 is provided on the discharge pipe 10, and a detachable filter collection bag 16 is provided below the discharge pipe 10.

[0020] In this embodiment: Under normal filtration conditions, the first electric butterfly valve 4 located at the two horizontal sections of the bend 2 and the second electric butterfly valve 5 located at the vertical section of the bend 2 remain open. Simultaneously, the two fourth electric butterfly valves 9 on the L-shaped pipe 8 and the third electric butterfly valve 11 on the discharge pipe 10 are closed. The dust-laden exhaust gas flowing from the activated carbon desulfurization tower body 1 enters the bend 2. Subsequently, the exhaust gas passes through the sintered metal mesh 3 installed in the two horizontal sections of the bend 2, where dust is trapped. The filtered clean gas is finally discharged through the right-side port of the bend 2.

[0021] When it is necessary to remove the accumulated dust on the sintered metal mesh 3, firstly close the two first electric butterfly valves 4 and the second electric butterfly valve 5, and simultaneously open the two fourth electric butterfly valves 9 and the two third electric butterfly valves 11. Then, start the centrifugal fan 7, and the high-pressure airflow generated is introduced into the right side of the two sintered metal meshes 3 through the L-shaped pipe 8. This reverse airflow penetrates the sintered metal mesh 3, blowing off the dust layer attached to it. The blown-off dust, carried by the airflow, enters the opened discharge pipe 10 and is guided downwards into the removable filter collection bag 16. The dust is trapped and collected, while the gas is discharged through the filter bag.

[0022] After dust removal is complete, the centrifugal fan 7 stops, the first electric butterfly valve 4 and the second electric butterfly valve 5 are reopened, and the fourth electric butterfly valve 9 and the third electric butterfly valve 11 are closed, restoring the filtration mode. This design achieves automated dust cleaning and collection, thereby greatly reducing maintenance workload.

[0023] As a technical optimization of this utility model, an internally threaded cylinder 12 is fixedly connected to the outer wall of the discharge pipe 10, and a connection port 14 is connected to the inner thread of the internally threaded cylinder 12. A ring plate 15 is fixedly connected to the lower end of the connection port 14, and a filter collection bag 16 is fixedly connected to the lower end of the ring plate 15. A sealing gasket 13 that abuts against the upper edge of the connection port 14 is embedded in the top of the inner wall of the internally threaded cylinder 12 through a groove.

[0024] In this embodiment: when it is necessary to clean the dust, the filter collection bag 16 can be removed from the internal threaded cylinder 12 by unscrewing the connection port 14, and the dust inside the filter collection bag 16 can be poured out from the connection port 14; during installation, the connection port 14 is screwed into the internal threaded cylinder 12, and the upper edge of the connection port 14 is pressed against the sealing gasket 13 to form a reliable seal.

[0025] As a technical optimization of this utility model, a fourth electric butterfly valve 9 is provided at both ends of the L-shaped pipe 8.

[0026] In this embodiment, a fourth electric butterfly valve 9 is installed at both ends of the L-shaped pipe 8, so that the two ends of the L-shaped pipe 8 can be closed under normal filtration conditions.

[0027] As a technical optimization of this utility model, a reinforcing plate 17 is fixedly connected between the activated carbon desulfurization tower body 1 and the bend 2.

[0028] In this embodiment: by setting the reinforcing plate 17, a rigid connection structure is formed between the activated carbon desulfurization tower body 1 and the bend 2, which improves the stability of the bend 2 installation.

[0029] As a technical optimization of this utility model, an operation panel 18 and a controller 19 are installed on the outer wall of the reinforcing plate 17.

[0030] In this embodiment: the operator can input commands through the operation panel 18. After receiving the commands, the controller 19 automatically controls the start and stop of the first electric butterfly valve 4, the second electric butterfly valve 5, the third electric butterfly valve 11, the fourth electric butterfly valve 9 and the centrifugal fan 7.

[0031] As a technical optimization of this utility model, a guide ring 20 is fixedly connected between the inner wall of the filter collection bag 16 and the lower end of the ring plate 15.

[0032] In this embodiment: by setting the guide ring 20, whose inner wall is a conical structure, it is convenient to pour out the dust inside the filter collection bag 16.

[0033] As a technical optimization of this utility model, a mounting frame 6 is fixedly connected between the reinforcing plate 17 and the bend 2, and the centrifugal fan 7 is installed on the outer wall of the mounting frame 6.

[0034] In this embodiment: by setting up the mounting bracket 6, a mounting base is provided for the installation of the centrifugal fan 7.

[0035] The working principle and usage process of this utility model are as follows: Under normal filtration conditions, the first electric butterfly valve 4 located at the two horizontal sections of the bend 2 and the second electric butterfly valve 5 located at the vertical section of the bend 2 remain open. Simultaneously, the two fourth electric butterfly valves 9 on the L-shaped pipe 8 and the third electric butterfly valve 11 on the discharge pipe 10 are closed. Dust-laden exhaust gas flowing from the activated carbon desulfurization tower body 1 enters the bend 2. Subsequently, the exhaust gas passes through the sintered metal mesh 3 installed in the two horizontal sections of the bend 2, where dust is trapped. The filtered clean gas is finally discharged through the right-side port of the bend 2.

[0036] When it is necessary to remove the accumulated dust on the sintered metal mesh 3, a command is issued through the operation panel 18. The controller 19 first closes the two first electric butterfly valves 4 and the second electric butterfly valve 5, while simultaneously opening the two fourth electric butterfly valves 9 and the two third electric butterfly valves 11. Subsequently, the centrifugal fan 7 is started, and the high-pressure airflow generated by it is introduced into the right side of the two sintered metal meshes 3 through the L-shaped pipe 8. This reverse airflow penetrates the sintered metal mesh 3, blowing off the dust layer attached to it. The blown-off dust is carried by the airflow into the opened discharge pipe 10 and guided downward into the removable filter collection bag 16. The dust is trapped and collected, while the gas is discharged through the filter bag.

[0037] After dust removal is complete, the centrifugal fan 7 stops, the first electric butterfly valve 4 and the second electric butterfly valve 5 are reopened, and the fourth electric butterfly valve 9 and the third electric butterfly valve 11 are closed, restoring the filtration mode. This design achieves automated dust cleaning and collection, thereby greatly reducing maintenance workload.
