Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization absorption towers, and specifically discloses a smoke exhaust device for a desulfurization absorption tower. Background Art

[0002] A desulfurization absorption tower is a device used to reduce the sulfur dioxide content in industrial waste gas. Its main function is to deeply treat the waste gas containing sulfur dioxide through an absorption liquid, so that the sulfide reacts with the absorption liquid, thereby reducing the sulfur dioxide content in the gas. The desulfurization absorption tower can also be used to treat waste gas and sewage containing other pollutants. The specific working principle of the desulfurization absorption tower is to spray the waste gas and sewage to be treated into the desulfurization absorption tower through a sprayer, and inject an absorption liquid (such as calcium hydroxide solution, etc.) so that the pollutants such as sulfur dioxide and hydrogen sulfide in the waste gas and sewage are absorbed by the absorption liquid, and then through chemical reactions, the sulfur dioxide and other substances in the waste gas and sewage are converted into non-volatile solid waste or recyclable liquid waste, thereby achieving the purpose of reducing air and water pollution.

[0003] The smoke outlet on the side or top of the desulfurization absorption tower is connected to a smoke outlet channel, which is mainly used to guide the flue gas produced during the operation of the desulfurization absorption tower, purify the flue gas containing a large amount of moisture and particulate matter produced in the desulfurization absorption tower, and discharge the purified flue gas into the atmosphere. At present, the desulfurization absorption tower is usually equipped with a smoke outlet between its smoke outlet and the smoke outlet channel; the utility model patent with the authorization announcement number: CN220558924U discloses a flue gas desulfurization absorption tower, in which the desulfurization absorption tower in the prior art allows the flue gas to enter the tower body from the smoke inlet, and then be discharged from the gas outlet after being processed by the spray layer and the demisting layer in turn. The above-mentioned gas outlet is a cylindrical structure, which is often called a smoke outlet by people in this field. The smoke output of the desulfurization absorption tower is proportional to the air intake. Since the functionality of the smoke outlet of the desulfurization absorption tower is poor, after the smoke discharged from the desulfurization absorption tower enters the smoke outlet channel, the smoke will diffuse into the entire smoke outlet channel, causing dirt to often adhere to the inner wall of the smoke outlet channel near the smoke outlet end. After long-term accumulation of this dirt, it is easy to affect the smoke output rate of the desulfurization absorption tower, thereby affecting the treatment process of industrial waste gas; and, since the existing smoke outlet of the desulfurization absorption tower is a fixed structure with poor flexibility, the size of the smoke outlet cannot be adjusted, thereby reducing the rate at which smoke passes through the smoke outlet channel, greatly reducing the treatment efficiency of industrial waste gas. Utility Model Content

[0004] Aiming at the problem that the smoke outlet of a desulfurization absorption tower has poor functionality and flexibility, thus leading to low industrial waste gas treatment efficiency, the utility model provides a smoke outlet device for a desulfurization absorption tower.

DETAILED DESCRIPTION

[0023] In order to make the purpose, features and advantages of the utility model more obvious and easy to understand, the technical scheme of the utility model will be clearly and completely described below in combination with the drawings in the specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the utility model, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0024] This specific embodiment provides a smoke outlet device for a desulfurization absorption tower, such as Figure 1-Figure 5 As shown; it includes a cover plate 1, which can be installed at the smoke outlet of the desulfurization absorption tower, the inner plate surface of the cover plate 1 can be tightly connected to the smoke outlet of the desulfurization absorption tower, and the smoke outlet channel used by the desulfurization absorption tower can be fixedly installed on the outer periphery of the cover plate 1, so that the desulfurization absorption tower and its smoke outlet channel are installed as an integrated structure. The first support 10 and the second support 11 are fixedly installed on the side end of the inner plate surface of the cover plate 1, and the first support 10 and the second support 11 are symmetrically installed on both sides. A rotating shaft 12 is arranged between the first support 10 and the second support 11, and the rotating shaft 12 can be rotatably installed at the smoke outlet of the desulfurization absorption tower. The first shaft seat 13 and the second shaft seat 14 are respectively installed at both ends of the rotating shaft 12, and the first shaft seat 13 and the second shaft seat 14 are tightly connected to the first support 10 and the second support 11 respectively. By setting the matching structure of the rotating shaft 12 and the first support 10 and the second support 11, the cover plate 1 can be rotatably installed at the smoke outlet of the desulfurization absorption tower, so as to facilitate the disassembly and assembly operations of the operators, thereby improving the flexibility of the device.

[0025] The cover plate 1 is provided with a first smoke outlet 2 and a second smoke outlet 3. The first smoke outlet 2 is a square outlet structure and is arranged at the center of the cover plate 1. The second smoke outlet 3 is a fan-shaped outlet structure and is arranged at the side of the first smoke outlet 2 and is connected to the first smoke outlet 2. Moreover, the opening area of ​​the second smoke outlet 3 is larger than the opening area of ​​the first smoke outlet 3. The flue gas flowing out of the smoke outlet of the desulfurization absorption tower can directly enter the smoke outlet channel through the first smoke outlet 2 and the second smoke outlet 3, thereby realizing the smoke circulation.

[0026] A cylinder 4 is fixedly mounted on the outer surface of the cover plate 1, and the cylinder body of the cylinder 4 is fixedly mounted on the outer surface of the cover plate 1 and arranged on the side of the first smoke outlet 2. A receiving seat 15 is fixedly connected to the end of the piston rod of the cylinder 4, and a slide bar 5 is fastened to the end surface of the receiving seat 15. The slide bar 5 is arranged in the first smoke outlet 2, and the length of the slide bar 5 is adapted to the transverse length of the first smoke outlet 2. Driven by the piston rod of the cylinder 4, the slide bar 5 can be displaced along the longitudinal side of the first smoke outlet 2, thereby adjusting the position of the slide bar 5 in the first smoke outlet 2.

[0027] A fixing block 16 is fixedly mounted on the outer plate surface of the cover plate 1, and the fixing block 16 is arranged at the side of the first smoke outlet 2. A limiting rod 17 facing the receiving seat 15 is fixedly mounted on the fixing block 16. By setting the matching structure of the fixing block 16 and the limiting rod 17, the position of the slide bar 5 can be limited, thereby ensuring the coordination of the overall device.

[0028] A turn bar 7 is rotatably mounted on the inner plate surface of the cover plate 1. One end of the turn bar 7 is hinged to the cover plate 1 through a second pin 18. Under the connection of the second pin 18, the turn bar 7 can be rotated in a pointer-like manner on the inner plate surface of the cover plate 1. The third support 19 and the fourth support 20 are arranged on both sides of the second pin 18. The third support 19 and the fourth support 20 are both tightly connected to the inner plate surface of the cover plate 1. The angle formed between the third support 19 and the fourth support 20 is adapted to the rotation angle of the turn bar 7, thereby limiting the rotation angle of the turn bar 7. A first pin 8 is mounted on the outer side surface of the turn bar 7. The first pin 8 is arranged in the middle of the turn bar 7. A slide groove 6 is provided on the inner side surface of the slide bar 5. The outer end of the first pin 8 is arranged in the slide groove 6 and slides with the slide groove 6. By setting the matching structure of the first pin 8 and the slide slot 6, the first pin 8 can be moved laterally along the slide slot 6, and at the same time, the rotation of the turn bar 7 can be ensured, thereby forming a matching structure. The other end of the turn bar 7 is fixedly connected to the fifth support 21 arranged in the second smoke outlet 3, and the side of the fifth support 21 is installed with a third pin 22, and the third pin 22 is slidably matched with the outer plate surface of the cover plate 1. By setting the third pin 22, the turn bar 7 can be supported when it rotates, thereby ensuring the stability of the turn bar 7 when it rotates.

[0029] A foldable folding plate 9 is arranged in the second smoke outlet 3, and the folded edge at one end of the folding plate 9 is tightly connected to the turning bar 7, and the folded edge at the other end of the folding plate 9 is tightly connected to the inner groove surface of the second smoke outlet 3. By setting the folding plate 9, the flow rate of smoke through the second smoke outlet 3 can be limited, thereby controlling the flow rate of smoke from the smoke outlet of the desulfurization absorption tower to the smoke outlet channel. In addition, the rotation angle of the turning bar 7 is the same as the fan-shaped arc of the second smoke outlet 3, thereby ensuring that the folding plate 9 can completely cover the second smoke outlet 3 when it is fully unfolded.

[0030] The working principle of the utility model is:

[0031] The operator can install the device between the smoke outlet of the desulfurization absorption tower and the smoke outlet channel. The first smoke outlet 2 in the device is a normally open smoke outlet, and the smoke generated in the desulfurization absorption tower can pass through the first smoke outlet 2. The second smoke outlet 3 is a movable smoke outlet. If the smoke generated in the desulfurization absorption tower is less, the folding plate 9 can be unfolded to close the second smoke outlet 3, so that the smoke flows out from the first smoke outlet 2; if the smoke generated in the desulfurization absorption tower is more, the operator can control the cylinder 4 to drive the slide bar 5 to slide in the first smoke outlet 2 according to the amount of smoke generated. Under the cooperation of the first pin shaft 8, the rotating bar 7 can be rotated on the inner plate surface of the cover plate 1, thereby pulling the folding plate 9, thereby controlling the opening size of the second smoke outlet 3, so as to adapt to the smoke generated in the desulfurization absorption tower, so as to ensure the passing rate of the smoke entering the smoke channel. Since the first smoke outlet 2 and the second smoke outlet 3 are both arranged inside the cover plate 1, when the smoke passes through the first smoke outlet 2 and the second smoke outlet 3, the smoke airflow flows out at a high speed, thereby ensuring that the smoke will not contact the inner wall of the smoke outlet channel near the smoke outlet end for a long time, avoiding the generation of dirt, thereby ensuring the smoke outlet rate of the desulfurization absorption tower.

[0032] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
