Description

Technical Field

[0001] This utility model relates to the field of flue gas treatment technology, and in particular to a noise reduction and dust removal device for steel chimneys. Background Technology

[0002] With the continuous development of science and technology, various heavy industries have gradually developed, such as thermal power plants and steel plants. During the production process, these factories generate a large amount of smoke and dust, which requires the use of tall chimneys to process and discharge the smoke and dust. Steel chimneys are commonly used because they have high strength, good corrosion resistance, and are easy to install.

[0003] While steel chimneys offer advantages in installation and ease of use, their overall height makes them susceptible to damage from strong airflows during certain weather conditions. This can create turbines and cause the chimney to vibrate, potentially leading to tilting over time. Furthermore, the accumulation of dust at the base of the chimney presents significant challenges in dust removal. Utility Model Content

[0007] In at least some embodiments, the stabilizing frame of the stabilizing component is configured as a hexagonal frame, the stabilizing frame is set on the ground position where the outer wall component is installed, and a vertical reinforcing frame is provided on the wall of the outer wall component, with a reinforcing rope connected to the top of the reinforcing frame and the end position of the stabilizing frame.

[0008] In at least some embodiments, the outer tube of the dust removal component is located at the bottom of the outer wall component, and the outer tube extends to the outer end of the outer wall component. A contact tube is located at the inner end of the outer tube, and an inner rotating tube is rotatably installed at the inner end of the contact tube.

[0010] In at least some embodiments, the inner wall cylinder of the inner wall assembly is located at the inner end of the outer wall assembly, a spacer is provided on the outer wall of the inner wall cylinder, and an outer pipe is provided at the bottom outer end of the area where the inner wall cylinder and the spacer cylinder of the outer wall assembly are in close contact.

[0011] In at least some embodiments, a support frame is provided on the outer wall of the top frame block of the top frame assembly, an outer groove is provided at the bottom of the wall of the top frame block, the upper end of the support frame of the top frame block is in an extended shape, and the top support frame of the top frame block is connected to the baffle plate.

[0012] This utility model provides a noise reduction and dust removal device for steel chimneys, which has the following beneficial effects:

[0013] In this invention, the outer wall assembly is first configured as a double-layered structure consisting of an outer wall cylinder and a spacer cylinder. The spacer cylinder has spiral strips to create a certain gap between the spacer cylinder and the outer wall cylinder. After adding filler, this better reduces overall noise. Simultaneously, a stabilizing component is installed at the bottom of the outer wall assembly, which increases the stability of the device. The dust removal component is connected to an external flue, allowing the inner rotating cylinder to rotate externally, facilitating the cleaning of dust filtered at the outer end of the inner rotating cylinder. An auxiliary component located near the dust removal component has an internal auxiliary component structure that increases the device's vibration damping effect, achieving overall noise reduction. After connecting the inner wall assembly to external pipelines, heat dissipation can be achieved through the inner wall assembly, ensuring the overall operation of the device.

[0014] Furthermore, a reinforcing ring is directly installed on the outer wall of the outer cylinder to reinforce it. The reinforcing plate at the bottom of the outer cylinder provides temperature support from the bottom, ensuring the overall stability of the device. To reduce noise in the outer wall assembly, a gap is created between the outer cylinder and the spacer cylinder, with the gap being spiral-shaped. This increases the overall stability of the outer wall assembly and further enhances noise reduction after the gap is filled. To ensure greater stability during installation, a stabilizing frame is installed at the bottom of the outer wall assembly on the ground. A reinforcing rope is connected to the top of the stabilizing frame, and the end of the rope is then attached to the end of the stabilizing frame for further reinforcement.

[0015] In addition, after the external cylinder is connected to the flue, the external cylinder is transmitted to the inner rotating cylinder through the contact cylinder. The inner rotating cylinder corresponds to the filter frame of the external cylinder, which can filter a certain amount of smoke and dust, thus assisting in the dust removal effect. When cleaning the filter frame of the inner rotating cylinder, the control block is adjusted from the outside using tools. The control block transmits to the gear disk at the bottom of the inner rotating cylinder through the transmission rod, causing the inner rotating cylinder to rotate and thus rotating the filter frame, thereby achieving the cleaning effect of the filter frame of the inner rotating cylinder.

[0016] In addition, to further stabilize the device, an auxiliary frame is fixed directly to the bottom of the inner end of the outer wall component. A stabilizing column is sleeved on the stabilizing cylinder of the auxiliary frame. The stabilizing column is set at the bottom of the spacer cylinder. The spring between the stabilizing column and the stabilizing cylinder can make the device more stable as a whole, thereby achieving a certain noise reduction effect.

[0017] In addition, to enable the device to have a certain cooling effect, a spacer is directly installed on the outer wall of the inner cylinder. Cooling material is injected into the outer part of the inner cylinder through the outer pipe of the spacer and then flows through the spacer structure of the inner cylinder to achieve the cooling effect of the inner wall components. When the device exhausts smoke, the top frame blocks are spaced at a certain distance by the support frame. At the same time, the outer groove of the top frame block can better exhaust the smoke and dust. The baffle structure on the top of the top frame block can better block the smoke and dust without hindering the exhaust of the smoke and dust. Attached Figure Description

[0036] This utility model proposes a noise reduction and dust removal device for steel chimneys, comprising: an outer wall assembly 1; a stabilizing assembly 2 is provided at the bottom of the outer wall assembly 1; a dust removal assembly 3 is installed on the inner side of the lower end of the outer wall assembly 1; an auxiliary assembly 4 is installed at the lower inner end of the outer wall assembly 1; an inner wall assembly 5 is installed on the auxiliary assembly 4; the inner wall assembly 5 is also located at the inner end of the outer wall assembly 1; and a top frame assembly 6 is installed at the top of the outer wall assembly 1.

[0037] In this embodiment of the disclosure, such as Figure 2 Figure 4 As shown, the outer wall assembly 1's outer wall cylinder 101 is configured as a vertical structure. A reinforcing ring 102 is provided on the outer wall of the outer wall cylinder 101, and a reinforcing plate 103 is installed on the bottom outer wall of the outer wall cylinder 101. The reinforcing plate 103 is configured as a triangular structure. The reinforcing ring 102 is directly installed on the outer wall of the outer wall cylinder 101, so that the reinforcing ring 102 can achieve the effect of reinforcing the outer wall cylinder 101. The reinforcing plate 103 at the bottom of the outer wall cylinder 101 can provide temperature support from the bottom of the outer wall cylinder 101, ensuring the overall stability of the device. For stabilization, a spacer cylinder 104 is sleeved and installed at the inner end of the outer wall cylinder 101. There is a gap between the spacer cylinder 104 and the outer wall cylinder 101. The gap between the spacer cylinder 104 and the outer wall cylinder 101 is supported by a spiral frame. First, in order to reduce the noise of the outer wall assembly 1 as a whole, a gap is directly set between the outer wall cylinder 101 and the spacer cylinder 104. At the same time, the gap between the outer wall cylinder 101 and the spacer cylinder 104 is set as a spiral shape, so as to increase the overall stability of the outer wall assembly 1 by the gap part, and at the same time, after the gap is filled, a better noise reduction effect is achieved.

[0038] In this embodiment of the disclosure, such as Figure 1 Figure 2 As shown, the stabilizing frame 201 of the stabilizing component 2 is set in the shape of a hexagonal frame. The stabilizing frame 201 is set on the ground position where the outer wall component 1 is installed. A vertical reinforcing frame 202 is set on the wall of the outer wall component 1. A reinforcing rope 203 is connected to the top of the reinforcing frame 202 and the end of the stabilizing frame 201. In order to make the device more stable during installation, the stabilizing frame 201 is directly set at the bottom of the outer wall component 1 where it is installed on the ground. At the same time, the top of the reinforcing frame 202 of the outer wall component 1 is connected to the reinforcing rope 203, and then the end of the reinforcing rope 203 is connected to the end of the stabilizing frame 201, so that the device can be further reinforced.

[0039] In this embodiment of the disclosure, such as Figure 2 Figure 4As shown, the outer casing 301 of the dust removal component 3 is located at the bottom of the outer wall component 1, extending to the outer end of the outer wall component 1. A contact casing 302 is located at the inner end of the outer casing 301, and an inner rotating casing 303 is rotatably mounted on the inner end of the contact casing 302. Filter frames are positioned on the inner rotating casing 303 and the contact casing 302 corresponding to the positions of the outer casing 301. After the outer casing 301 is connected to the flue, the outer casing 301 communicates with the inner rotating casing 303 through the contact casing 302. The inner rotating casing 303 corresponds to the filter frame of the outer casing 301, enabling the removal of dust. The inner rotating cylinder 303 has a gear disk at its bottom, which meshes with the transmission rod 304. The top of the transmission rod 304 is connected to the control block 305 via a bevel gear. When cleaning the filter screen of the inner rotating cylinder 303, the control block 305 is adjusted from the outside using tools. The control block 305 transmits power to the gear disk at the bottom of the inner rotating cylinder 303 through the transmission rod 304, causing the inner rotating cylinder 303 to rotate and thus rotate the filter screen, achieving the cleaning effect of the filter screen of the inner rotating cylinder 303.

[0040] In this embodiment of the disclosure, such as Figure 3 Figure 5 As shown, the auxiliary frame 401 of the auxiliary component 4 is located at the inner end of the outer wall component 1. The auxiliary frame 401 is provided with six sets of stabilizing cylinders 402, which are connected and fixed to each other. Stabilizing columns 403 are sleeved on the stabilizing cylinders 402. Springs are added to the stabilizing columns 403 and the stabilizing cylinders 402. In order to further stabilize the device, the auxiliary frame 401 is directly fixed at the bottom of the inner end of the outer wall component 1. Stabilizing columns 403 are sleeved on the stabilizing cylinders 402 of the auxiliary frame 401. The stabilizing columns 403 are located at the bottom of the spacer cylinder 104. The springs between the stabilizing columns 403 and the stabilizing cylinders 402 can make the whole device more stable, thereby achieving a certain noise reduction effect.

[0041] In this embodiment of the disclosure, such as Figure 5 Figure 6 As shown, the inner wall cylinder 501 of the inner wall assembly 5 is located at the inner end of the outer wall assembly 1. A spacer 503 is provided on the outer wall of the inner wall cylinder 501. An outer pipe 502 is provided at the bottom outer end of the inner wall cylinder 501 where it is in close contact with the spacer cylinder 104 of the outer wall assembly 1. In order to enable the device to have a certain cooling effect, the spacer 503 is directly provided on the outer wall of the inner wall cylinder 501. After the cooling material is injected into the outside of the inner wall cylinder 501 through the outer pipe 502 of the spacer cylinder 104, it flows through the spacer 503 structure of the inner wall cylinder 501, thereby achieving the cooling effect of the inner wall assembly 5.

[0042] In this embodiment of the disclosure, such as Figure 1 Figure 3As shown, a support frame is provided on the outer wall of the top frame block 601 of the top frame assembly 6. An outer groove 602 is provided at the bottom of the wall of the top frame block 601. The upper end of the support frame of the top frame block 601 is protruding. The top support frame of the top frame block 601 is connected to the baffle plate 603. When the device exhausts smoke, the top frame block 601 is spaced a certain distance apart by the support frame. At the same time, the outer groove 602 of the top frame block 601 can better exhaust the smoke and dust. The structure of the baffle plate 603 at the top of the top frame block 601 can better block the smoke and dust without hindering the exhaust of the smoke and dust.

[0043] The working principle of this embodiment is as follows: During installation, the stabilizing frame 201 of the stabilizing component 2 needs to be erected first. Then, the auxiliary component 4 is installed at the bottom of the inner wall component 5. At the same time, the dust removal component 3 is rotated and installed at the inner end of the auxiliary component 4. The dust removal component 3 is located at the inner end of the inner wall component 5. The outer wall component 1 is installed as a whole at the outer end of the inner wall component 5. At the same time, the outer wall component 1 is wrapped around the outer end of the dust removal component 3, so that the outer wall component 1 and the auxiliary component 4 are in contact and fixed to each other. At this time, the stabilizing component 2 connects and reinforces the outer end of the outer wall component 1.

[0044] During installation, the external flue is directly connected to the external cylinder 301. When cleaning the dust entering the flue is required, the dust removal component 3 is rotated from the outside to assist in cleaning the debris filtered by the dust removal component 3. The bottom of the inner wall component 5 is connected to the external pipe to allow the inner wall component 5 to be injected with a cooling liquid, which helps to improve the overall heat dissipation of the device.
