Method for adjusting nozzle water flow of tail gas absorption tower

Abstract

A method for adjusting the nozzle water flow in a tail gas absorption tower. Traditional tail gas absorption tower nozzle assemblies have the advantages of simple structure and convenient installation, but they still have their shortcomings. The method of the present invention is as follows: when it is necessary to adjust the water flow rate according to the tail gas emission speed in the tail gas absorption tower, a motor (501) can drive a first rotating shaft (502) to rotate. The first rotating shaft (502) drives a secondary bevel gear (504) to rotate through a main bevel gear (503). The secondary bevel gear (504) drives a rotating wheel (506) to rotate through a second rotating shaft (505). This causes the holes on the rotating wheel (506) and the holes on the fixed wheel (509) to intersect, allowing water to pass through. The size of the intersection of the holes directly affects the water flow rate, thereby controlling the nozzle water flow rate.

Description

Technical Field

[0001] This invention relates to the field of exhaust gas absorption tower technology, specifically to a method for adjusting the nozzle water flow of an exhaust gas absorption tower. Background Technology

[0002] Tail gas absorption towers, also known as waste gas purification towers, waste gas treatment towers, acid mist purification towers, and acid mist treatment towers, are mainstream waste gas treatment equipment in environmental protection equipment. They are high-efficiency waste gas absorption towers with low pressure loss. These towers retain the advantages of polypropylene equipment, such as corrosion resistance, lightweight and high strength, and resistance to scaling, while significantly improving mass transfer efficiency. Tail gas absorption towers typically use a spray method to absorb the liquid-soluble components of the exhaust gas. Therefore, the nozzle assembly is a crucial part of the tail gas absorption tower. Traditional tail gas absorption tower nozzle assemblies are simple in structure and easy to install, but they still have shortcomings. Therefore, we introduce a method for adjusting the nozzle water flow in tail gas absorption towers.

[0003] Existing patent (publication number: CN217594237U) discloses a spraying device for a phosphoric acid absorption tower, including a feed pipe, a connecting pipe, an outer ring pipe, an inner ring pipe, a nozzle, a connecting pipe, a pad, a support beam, U-bolts, and nuts. Its advantages are: this invention uses an annular anti-clogging nozzle inside the phosphoric acid absorption tower, ensuring uniform spraying without dead angles within the tower diameter, resulting in good spraying and ammonia removal effects. The nozzles are less prone to clogging, ensuring long-term stable operation of the equipment. It is suitable for phosphoric acid absorption towers of any diameter. In the process of developing this invention, the inventors discovered the following problems with the existing technology: 1. Existing tail gas absorption towers do not allow for convenient adjustment of the nozzle spray volume as needed, easily leading to water waste; 2. The existing tail gas absorption towers mainly use sealing rings to seal the nozzles and water pipes, but these sealing rings wear down under prolonged water flow, causing a decrease in the seal between the nozzles and water pipes. Summary of the Invention

[0004] The purpose of this invention is to provide a method for adjusting the nozzle water flow of a tail gas absorption tower, in order to solve the problems mentioned in the background art, such as the inconvenience of adjusting the spray volume of the nozzle in existing tail gas absorption towers as needed, which easily leads to poor operating parameters; and the fact that the sealing between the nozzle and the water pipe of existing tail gas absorption towers is mainly achieved by sealing rings, but the sealing rings will be worn down under the scouring of water flow for a long time, resulting in a decrease in the sealing performance between the nozzle and the water pipe.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A method for adjusting the nozzle water flow of a tail gas absorption tower: First, align the limiting grooves (8) on both sides of the water pipe (9) with the limiting strips (7) on the inner wall of the connector (2), and insert the water pipe (9) into the connector (2). At this time, the front end of the water pipe (9) will open the second sealing ring (604), and the front end of the water pipe (9) will contact the first sealing ring (603). The first sealing ring (603) will squeeze the first spring (601). Under the reaction force of the first spring (601), the first sealing ring (603) will be tightly attached to the front end of the water pipe (9), making the sealing effect better. The second sealing ring (604) is embedded in the inner wall of the connector (2), avoiding the water flow from directly scouring the second sealing ring (604), making the second sealing ring (604) more secure. The sealing ring (604) can achieve a better sealing effect and will not be worn out under the long-term scouring of water flow, which will lead to a decrease in the sealing between the nozzle and the water pipe (9). When it is necessary to adjust the water flow rate according to the exhaust gas emission speed in the exhaust gas absorption tower, the first rotating shaft (502) can be driven to rotate by the motor (5010). The first rotating shaft (502) drives the secondary bevel gear (504) to rotate through the main bevel gear (503). The secondary bevel gear (504) will drive the rotating wheel (506) to rotate through the second rotating shaft (505), so that the holes on the rotating wheel (506) and the holes on the fixed wheel (509) intersect, allowing water to pass through. The size of the hole intersection directly affects the water flow rate, thereby controlling the nozzle water flow rate.

[0007] A nozzle assembly for a tail gas absorption tower includes a nozzle body, a connector fixedly connected to one end of the nozzle body, and a nozzle fixedly connected to the other side of the nozzle body. The nozzle has several water outlet holes in its center. An adjustment assembly is located in the center of the nozzle body. A sealing assembly is located inside the connector. Two limiting strips are fixedly connected to the inner wall of the connector. The two limiting strips are movably connected to the center of a limiting groove. The limiting groove is located on both sides of a water pipe. Two threaded holes are located on the outer side of the water pipe, and a fixing screw is threaded into the center of each of the two threaded holes.

[0008] The adjustment assembly includes a motor fixedly connected to the outside of the nozzle body. The output end of the motor is fixedly connected to a first rotating shaft. One end of the first rotating shaft is fixedly connected to a main bevel gear. A secondary bevel gear meshes with one side of the main bevel gear. A second rotating shaft passes through the middle of the secondary bevel gear. One end of the second rotating shaft is fixedly connected to a rotating wheel, and the other end of the second rotating shaft is movably connected to a bearing sleeve. A connecting rod is fixedly connected to the outside of the bearing sleeve, and a fixed wheel is provided on one side of the rotating wheel.

[0009] More preferably, the sealing assembly includes a first spring and a second spring fixedly connected inside the connector, with a first sealing ring fixedly connected to one end of the first spring and a second sealing ring fixedly connected to one end of the second spring.

[0010] More preferably, the first spring and the second spring are perpendicular to each other.

[0011] More preferably, the connector and the water pipe are connected by a limiting strip and a limiting groove to form a limiting structure.

[0012] More preferably, the front end of the water pipe has a tapered structure.

[0013] More preferably, the rotating wheel and the fixed wheel each have two holes.

[0014] More preferably, the main bevel gear and the secondary bevel gear cooperate to form a transmission structure.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] A method for adjusting the nozzle water flow of a tail gas absorption tower: First, align the limiting grooves (8) on both sides of the water pipe (9) with the limiting strips (7) on the inner wall of the connector (2), and insert the water pipe (9) into the connector (2). At this time, the front end of the water pipe (9) will open the second sealing ring (604), and the front end of the water pipe (9) will contact the first sealing ring (603). The first sealing ring (603) will squeeze the first spring (601). Under the reaction force of the first spring (601), the first sealing ring (603) will be tightly attached to the front end of the water pipe (9), making the sealing effect better. The second sealing ring (604) is embedded in the inner wall of the connector (2), avoiding the water flow from directly scouring the second sealing ring (604), making the second sealing ring (604) more secure. The sealing ring (604) can achieve a better sealing effect and will not be worn out under the long-term scouring of water flow, which will lead to a decrease in the sealing between the nozzle and the water pipe (9). When it is necessary to adjust the water flow rate according to the exhaust gas emission speed in the exhaust gas absorption tower, the first rotating shaft (502) can be driven to rotate by the motor (5010). The first rotating shaft (502) drives the secondary bevel gear (504) to rotate through the main bevel gear (503). The secondary bevel gear (504) will drive the rotating wheel (506) to rotate through the second rotating shaft (505), so that the holes on the rotating wheel (506) and the holes on the fixed wheel (509) intersect, allowing water to pass through. The size of the hole intersection directly affects the water flow rate, thereby controlling the nozzle water flow rate.

[0017] In this invention, a motor drives a first rotating shaft to rotate, which in turn drives a secondary bevel gear to rotate via a main bevel gear. The secondary bevel gear then drives a rotating wheel to rotate via a second rotating shaft, causing the holes on the rotating wheel and the holes on the fixed wheel to intersect, allowing water to pass through. The size of the intersection of the holes directly affects the water flow rate, thereby achieving the purpose of controlling the water flow rate of the nozzle.

[0018] In this invention, the first sealing ring is pressed against the first spring by the front end of the water pipe. Under the reaction force of the first spring, the first sealing ring is pressed tightly against the front end of the water pipe, resulting in a better sealing effect. The second sealing ring is embedded in the inner wall of the connector, which prevents the water flow from directly scouring the second sealing ring. This allows the second sealing ring to achieve a better sealing effect and prevents it from being worn down by the water flow over a long period of time, thus avoiding a decrease in the seal between the nozzle and the water pipe.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] A method for adjusting the nozzle water flow of a tail gas absorption tower: First, align the limiting grooves (8) on both sides of the water pipe (9) with the limiting strips (7) on the inner wall of the connector (2), and insert the water pipe (9) into the connector (2). At this time, the front end of the water pipe (9) will open the second sealing ring (604), and the front end of the water pipe (9) will contact the first sealing ring (603). The first sealing ring (603) will squeeze the first spring (601). Under the reaction force of the first spring (601), the first sealing ring (603) will be tightly attached to the front end of the water pipe (9), making the sealing effect better. The second sealing ring (604) is embedded in the inner wall of the connector (2), avoiding the water flow from directly scouring the second sealing ring (604), making the second sealing ring (604) more secure. The sealing ring (604) can achieve a better sealing effect and will not be worn out under the long-term scouring of water flow, which will lead to a decrease in the sealing between the nozzle and the water pipe (9). When it is necessary to adjust the water flow rate according to the exhaust gas emission speed in the exhaust gas absorption tower, the first rotating shaft (502) can be driven to rotate by the motor (5010). The first rotating shaft (502) drives the secondary bevel gear (504) to rotate through the main bevel gear (503). The secondary bevel gear (504) will drive the rotating wheel (506) to rotate through the second rotating shaft (505), so that the holes on the rotating wheel (506) and the holes on the fixed wheel (509) intersect, allowing water to pass through. The size of the hole intersection directly affects the water flow rate, thereby controlling the nozzle water flow rate.

[0026] This invention provides a technical solution: a nozzle assembly for a tail gas absorption tower, comprising a nozzle body 1, a connector 2 fixedly connected to one end of the nozzle body 1, and a nozzle 3 fixedly connected to the other side of the nozzle body 1, a plurality of water outlet holes 4 opened in the middle of the nozzle 3, an adjustment component 5 provided in the middle of the nozzle body 1, a sealing component 6 provided inside the connector 2, two limiting strips 7 fixedly connected to the inner wall of the connector 2, the two limiting strips 7 being movably connected to the middle of the limiting groove 8, the limiting groove 8 being opened on both sides of the water pipe 9, and two threaded holes 10 being opened on the outer side of the water pipe 9, each of the two threaded holes 10 being threadedly connected to a fixing screw 11 in the middle;

[0027] The adjustment assembly 5 includes a motor 501 fixedly connected to the outside of the nozzle body 1. The output end of the motor 501 is fixedly connected to a first rotating shaft 502. One end of the first rotating shaft 502 is fixedly connected to a main bevel gear 503. A secondary bevel gear 504 meshes with one side of the main bevel gear 503. A second rotating shaft 505 passes through the middle of the secondary bevel gear 504. One end of the second rotating shaft 505 is fixedly connected to a rotating wheel 506, and the other end of the second rotating shaft 505 is movably connected to a bearing sleeve 507. A connecting rod 508 is fixedly connected to the outside of the bearing sleeve 507. A fixed wheel 509 is provided on one side of the rotating wheel 506.

[0028] In this embodiment, as Figure 1As shown, the sealing assembly 6 includes a first spring 601 and a second spring 602 fixedly connected inside the connector 2. One end of the first spring 601 is fixedly connected to a first sealing ring 603, and one end of the second spring 602 is fixedly connected to a second sealing ring 604.

[0029] In this embodiment, as Figure 1 As shown, the first spring 601 and the second spring 602 are perpendicular to each other; thus, the first spring 601 and the second spring 602 apply forces to the first sealing ring 603 and the second sealing ring 604 in the axial and vertical directions respectively, making the sealing rings tightly fit with the water pipe 9. Furthermore, the second sealing ring 604 is embedded in the inner wall of the connector 2, which prevents the water flow from directly scouring the second sealing ring 604, allowing the second sealing ring 604 to achieve a better sealing effect and preventing wear and tear under the scouring of water flow over a long period of time, which would lead to a decrease in the sealing performance between the nozzle and the water pipe 9.

[0030] In this embodiment, as Figure 3 and Figure 4 As shown, the connector 2 and the water pipe 9 are connected by a limiting strip 7 and a limiting groove 8 to form a limiting structure; when the water pipe 9 is inserted into the connector 2, the limiting strip 7 can quickly position the water pipe 9 so that the threaded hole 10 on the outside of the water pipe 9 is aligned with the fixing screw 11, without having to spend time rotating the water pipe 9 to adjust the position of the threaded hole 10.

[0031] In this embodiment, as Figure 1 and Figure 4 As shown, the front end of the water pipe 9 has a tapered structure; the tapered structure makes it easier for the water pipe 9 to open the second sealing ring 604 when it is inserted into the connector 2.

[0032] In this embodiment, as Figure 1 and Figure 3 As shown, two holes are respectively opened on the rotating wheel 506 and the fixed wheel 509; so that when the rotating wheel 506 rotates, the hole on the rotating wheel 506 can gradually align with the hole on the fixed wheel 509, thereby releasing water.

[0033] In this embodiment, as Figure 1 As shown, the main bevel gear 503 and the secondary bevel gear 504 cooperate to form a transmission structure; the motor 501 can rotate the pulley 506 through the transmission structure, so that the holes on the rotating wheel 506 and the holes on the fixed wheel 509 intersect, allowing water to pass through. The size of the intersection of the holes directly affects the water flow rate, thereby achieving the purpose of controlling the water flow rate of the nozzle.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
