Description

Technical Field

[0001] The utility model belongs to the technical field of kiln tail gas treatment, and more specifically, it particularly relates to a desulfurization and dust removal device for the tail gas of a water glass kiln. Background Art

[0002] Sodium silicate, commonly known as water glass, is an inorganic substance. Its aqueous solution is commonly known as water glass and is a mineral binder. Its products usually include solid water glass, hydrated water glass, and liquid water glass. During the production process, a large amount of tail gas such as soot, nitrogen oxides, and sulfur dioxide will be generated in the kiln, and the tail gas needs to be treated before it can be discharged.

[0003] Chinese Patent CN219494879U discloses a desulfurization and dust removal device for the flue gas of a glass kiln, belonging to the technical field of glass production. A desulfurization and dust removal device for the flue gas of a glass kiln includes a desulfurization barrel, a smoke inlet pipe, a filter pipe, a servo motor, a filter disc, and an ash knocking mechanism. The upper side of the middle part of the desulfurization barrel is connected with the smoke inlet pipe. The lower part of the smoke inlet pipe penetrates into the inside of the desulfurization barrel. The top of the smoke inlet pipe is connected with the filter pipe. The top of the desulfurization barrel is connected with the servo motor. The output shaft of the servo motor is connected with the filter disc. The filter disc is slidably connected to the bottom of the filter pipe and is slidably connected to the top of the smoke inlet pipe. An ash knocking mechanism for knocking and removing ash from the filter disc is provided on the desulfurization barrel.

[0004] When replacing the filtering component for filtering flue gas in the existing device, it is relatively inconvenient. It is impossible to always ensure that the filtering component is in a clean state, and the subsequent cleaning operation is rather troublesome. In the above document, when controlling the knocking piece to knock the filter disc, it is possible to clean the filtering component without disassembling the filtering component. However, its filter pipe is located inside the filter disc, and the filter pipe needs to be close to the filter disc to avoid the leakage of tail gas. At this time, when the filter disc rotates, the soot on the filter disc is always covered by the filter pipe, which is not convenient for clearing the soot from the filter disc.

Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments.

[0030] Please refer to Figures 1-6 As shown in the figure, the present utility model is a desulfurization and dust removal device for the tail gas of a water glass kiln, including a desulfurization barrel (1). The top of the desulfurization barrel (1) is fixedly connected with a first pipeline (2) and a second pipeline (3). The first pipeline (2) and the second pipeline (3) are mutually communicated. The top of the desulfurization barrel (1) is rotatably connected with a filter assembly (4). The bottom of the filter assembly (4) is provided with an ash cleaning assembly (5). The ash cleaning assembly (5) is fixedly connected with the desulfurization barrel (1). The outer surface of the desulfurization barrel (1) is fixedly connected with a dust suction assembly (6). The filter assembly (4) is used to block and filter the tail gas in the first pipeline (2) and the second pipeline (3).

[0031] The tail gas in the water glass kiln enters the first pipe 2 and the second pipe 3. The rotary filter assembly 4 is rotated to block the first pipe 2 with the filter assembly 4. At this time, the tail gas can enter the desulfurization tank 1 through the second pipe 3 for desulfurization treatment. When there is a large amount of soot accumulated in the filter assembly 4 at the second pipe 3, the filter assembly 4 is rotated counterclockwise by 90 degrees. At this time, the filter assembly 4 blocks the second pipe 3, and the tail gas can enter the desulfurization tank 1 from the first pipe 2. The filter assembly 4 with soot inside rotates above the dust cleaning assembly 5, and the dust cleaning assembly 5 knocks down the dust inside it. At the same time, the dust suction assembly 6 above the filter assembly 4 is started to suck away the cleaned dust.

[0032] Through the connection of the filter assembly 4, the first pipe 2 and the second pipe 3, the rotation of the filter assembly 4 to different positions can control the on-off of the first pipe 2 and the second pipe 3. When there is a large amount of soot accumulated in the filter assembly 4 at the second pipe 3, the filter assembly 4 is rotated to block the second pipe 3, and at the same time the first pipe 2 is conducted. The filter assembly 4 with soot inside can be rotated between the dust cleaning assembly 5 and the dust suction assembly 6 to process the soot, which is convenient for cleaning the soot without affecting the normal treatment of the tail gas.

[0033] In one embodiment, for the above-mentioned filter assembly 4, the filter assembly (4) includes a rotating shaft (401). The top of the rotating shaft (401) is fixedly connected with a rotating frame (402). The outer surface of the rotating frame (402) is fixedly connected with a plurality of blocking rings (403) and filter rings (404) respectively. The rotating shaft (401) is rotatably connected to the top of the desulfurization tank (1). The blocking ring (403) and the filter ring (404) are respectively connected to the first pipe (2) and the second pipe (3).

[0034] The rotating shaft 401 drives the rotating frame 402 to rotate, and the rotating frame 402 drives the blocking ring 403 and the filter ring 404 to rotate. When the blocking ring 403 is connected to the first pipe 2, the first pipe 2 is blocked, and at the same time the filter ring 404 is connected to the second pipe 3, and the tail gas can pass through the second pipe 3 and the filter ring 404 into the desulfurization tank 1. Similarly, when the second pipe 3 is connected to the blocking ring 403, the second pipe 3 is blocked, and the tail gas can pass through the first pipe 2 and the filter ring 404 into the desulfurization tank 1.

[0036] When the filter ring 404 containing the ash rotates to the top of the support 503, the first motor 501 under the support 503 is started, and the first motor 501 drives the cam 502 to rotate. The cam 502 pushes the sliding rod 505 to slide up and down in the fixed cylinder 504. When the sliding rod 505 moves upward, the spring 506 is compressed. At the same time, the sliding rod 505 hits the bottom of the support 503, and the support 503 vibrates to make the ash fall off the inner wall of the filter ring 404. When the sliding rod 505 moves downward, the spring 506 can push the sliding rod 505 to return to its original position.

[0037] In one embodiment, for the above-mentioned dust collection component 6, the dust collection component (6) includes a negative pressure dust collector (601), the outer surface of the negative pressure dust collector (601) is fixedly connected to a main dust collection pipe (602), the outer surface of the main dust collection pipe (602) is fixedly connected to an auxiliary dust collection pipe (603), the end of the auxiliary dust collection pipe (603) is fixedly connected to a collection box (604), and the collection box (604) is located at the bottom of the support (503).

When cleaning the ash in the filter ring 404, part of the ash will pass through the filter ring 404 and fall on the support 503. When the filter ring 404 rotates, it can drive this part of the ash to fall into the collection box 604 under the support 503.

[0041] In one embodiment, for the above-mentioned desulfurization barrel 1, a support assembly 9 is fixedly connected to the top of the desulfurization barrel (1). The support assembly 9 is respectively used for supporting and fixing the second motor (7), the reducer (8), and the negative pressure dust collector (601).

Through the connection of the filtering component 4, the first pipeline 2, and the second pipeline 3, when the filtering component 4 rotates to different positions, the on-off of the first pipeline 2 and the second pipeline 3 can be controlled. When there is more dust accumulated on the filtering component 4 at the second pipeline 3, rotate the filtering component 4 to block the second pipeline 3, and at the same time, the first pipeline 2 is conducted. The filtering component 4 with dust inside can rotate between the dust cleaning component 5 and the dust suction component 6 to process the dust, which is convenient for cleaning the dust without affecting the normal treatment of the tail gas; 2. Through the connection of the sealing ring 403, the filtering ring 404, the first pipeline 2, and the second pipeline 3, when the sealing ring 403 is connected to the first pipeline 2, the first pipeline 2 is blocked, and at the same time, the filtering ring 404 is connected to the second pipeline 3. The tail gas can pass through the second pipeline 3 and the filtering ring 404 and enter the desulfurization barrel 1.
