Description

Technical Field

[0001] The present invention relates to the technical field of desulfurization nozzle devices, in particular to a desulfurization nozzle device with an anti-blocking function. Background Art

[0002] Current power plants are generally equipped with a flue gas desulfurization equipment, which contains a desulfurization nozzle. Since the liquid sprayed from the desulfurization nozzle is generally a slurry, in order to allow part of the flue gas to fully react with the liquid, the liquid sprayed from the desulfurization nozzle needs to be dispersed.

[0003] The current dispersion treatment for desulfurization liquid is to guide the liquid onto a rotating disc so that the liquid is dispersed. However, the liquid will be uneven when it is sprayed out, resulting in the liquid on the disc being not dispersed evenly enough. Therefore, grooves are cut on the disc and multiple openings are opened to allow the liquid to be sprayed out, reducing the flow rate of the liquid on the disc. However, when the liquid is relatively viscous, the openings will be blocked, resulting in poor liquid dispersion effect. Summary of the Invention

[0004] To address the deficiencies of the prior art, the present invention provides a desulfurization nozzle device with an anti-blocking function, which solves the problem that when the liquid is relatively viscous, the openings will be blocked, resulting in poor liquid dispersion.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A desulfurization nozzle device with an anti-blocking function comprises a main pipeline, a sliding pipe is slidably mounted on the main pipeline, a liquid outlet pipe connected thereto is fixedly mounted on the sliding pipe, a bottom plate is fixedly mounted on the liquid outlet pipe, and multiple groups of liquid outlets are provided on the bottom plate and the liquid outlet pipe;

[0007] The main pipeline is equipped with an anti-blocking device to prevent the desulfurization nozzle from being blocked;

[0008] The sliding tube is provided with a diversion device for allowing the liquid to fully react;

[0009] A driving device is installed on the main pipeline. When the driving device is started, the anti-blocking device drives the sliding pipe to move up and down on the main pipeline, and also drives the diverter device to rotate.

[0010] Preferably, the anti-blocking device includes a reciprocating screw fixedly mounted on the main pipeline and threadedly connected to the sliding tube, the reciprocating screw is provided with a connecting channel communicating with the main pipeline, and the sliding tube is fixedly mounted with an external gear ring.

[0011] Preferably, the anti-blocking device further comprises a support plate fixedly mounted on the connecting channel, a support column is rotatably mounted on the support plate, and a liquid separator is fixedly mounted on the support column.

[0012] Preferably, the anti-blocking device further comprises a plurality of groups of connecting rods fixedly mounted on the reciprocating screw rod, and a scraper for use with the liquid outlet pipe is fixedly mounted on each group of the connecting rods.

[0013] Preferably, the diversion device includes an inner gear ring fixedly mounted on the sliding tube, a rotating rod is rotatably mounted on the reciprocating screw, and a connecting gear meshing with the inner gear ring is fixedly mounted on the rotating rod.

[0014] Preferably, the diversion device further comprises a sprocket fixedly mounted on the rotating rod and the support column, a chain is wound around the sprocket, and a plurality of groups of connecting plates are fixedly mounted on the liquid separation plate, and each group of the connecting plates is provided with a liquid separation groove.

[0015] Preferably, the driving device includes a motor fixedly mounted on the main pipeline, a fixing rod fixedly mounted on the output end of the motor, and a driving gear meshing with the outer gear ring fixedly mounted on one end of the fixing rod.

[0016] Preferably, a connecting pipe is fixedly installed on the main pipeline, and a mounting groove communicating with the main pipeline is opened on the connecting pipe.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention sets an anti-blocking device. By starting the motor, the sliding tube drives the liquid outlet pipe and the bottom plate to rotate while also moving up and down, so that the bottom of the liquid separation plate is in constant contact with the bottom plate and the liquid in the liquid outlet pipe is pressed out through the liquid outlet. While the liquid outlet pipe rotates, the scraper also cleans the inner wall of the liquid outlet pipe, avoiding the situation where the opening is blocked when the liquid is relatively viscous, resulting in poor liquid dispersion effect.

[0019] 2. The present invention sets a diversion device, and the sliding tube rotates to drive the liquid separation plate connected to the support column to rotate, and the rotation of the liquid separation plate drives the connection plate to rotate. When the liquid flows to the rotating liquid separation plate through the connecting pipe, the liquid is diffused to the inner wall and bottom plate of the liquid outlet pipe under the action of the connecting plate and the liquid separation groove. The liquid on the inner wall of the liquid outlet pipe is discharged through the liquid outlet through the rotating liquid outlet pipe. The liquid can be sprayed evenly from the liquid outlet and the reaction effect of the liquid and the flue gas is better. BRIEF DESCRIPTION OF THE DRAWINGS

In order to solve this problem, refer to Figures 1-4 This embodiment proposes a desulfurization nozzle device with an anti-blocking function, including a main pipeline 1, a sliding pipe 11 is slidably installed on the main pipeline 1, a liquid outlet pipe 12 connected thereto is fixedly installed on the sliding pipe 11, a bottom plate 13 is fixedly installed on the liquid outlet pipe 12, and multiple groups of liquid outlet ports 14 are provided on the bottom plate 13 and the liquid outlet pipe 12 for liquid outflow, a connecting pipe 5 is fixedly installed on the main pipeline 1, and a mounting groove 51 connected to the main pipeline 1 is provided on the connecting pipe 5, and the desulfurization nozzle is installed on the equipment through the mounting groove 51;

[0029] An anti-blocking device 2 is installed on the main pipeline 1 to prevent the desulfurization nozzle from being blocked, and a diversion device 3 is installed on the sliding tube 11 to allow the liquid to react fully. A driving device 4 is installed on the main pipeline 1. When the driving device 4 is started, the anti-blocking device 2 drives the sliding tube 11 to move up and down on the main pipeline 1, and also drives the diversion device 3 to rotate, so that the liquid can react fully with the flue gas.

[0030] The anti-blocking device 2 includes a reciprocating screw rod 21 fixedly mounted on the main pipeline 1 and threadedly connected to the sliding tube 11, a connecting channel 22 communicating with the main pipeline 1 is provided on the reciprocating screw rod 21, an outer gear ring 23 is fixedly mounted on the sliding tube 11, the anti-blocking device 2 also includes a support plate 24 fixedly mounted on the connecting channel 22, a support column 25 is rotatably mounted on the support plate 24, a liquid separator 26 is fixedly mounted on the support column 25, the anti-blocking device 2 also includes a plurality of groups of connecting rods 27 fixedly mounted on the reciprocating screw rod 21, each group of connecting rods 27 is fixedly mounted with a scraper 28 used in conjunction with the liquid outlet pipe 12, and the driving device 4 includes a motor 41 fixedly mounted on the main pipeline 1 through the scraper 28, and the output end of the motor 41 is fixedly mounted with a fixed rod 42, One end of the rod 42 is fixedly mounted with a driving gear 43 that meshes with the outer gear ring 23. When the liquid enters the main pipeline 1 and the connecting pipe 5 in sequence through the connecting pipe 5, the motor 41 is started to rotate the fixed rod 42 at the output end to drive the driving gear 43 to rotate. The driving gear 43 rotates and drives the sliding tube 11 connected to the outer gear ring 23 to rotate on the reciprocating screw 21, so that the sliding tube 11 drives the liquid outlet pipe 12 and the bottom plate 13 to rotate while also moving up and down, so that the bottom of the liquid separation plate 26 is in continuous contact with the bottom plate 13 and the liquid in the liquid outlet pipe 12 is pressed out through the liquid outlet 14.

[0031] Example 2

[0032] Since the liquid can be sprayed evenly from the liquid outlet, the reaction effect with the flue gas will be improved. In order to solve this problem, refer to Figures 1-4The diversion device 3 includes an inner gear ring 31 fixedly mounted on the sliding tube 11, a rotating rod 32 is rotatably mounted on the reciprocating screw 21, and a connecting gear 33 meshing with the inner gear ring 31 is fixedly mounted on the rotating rod 32. The diversion device 3 also includes a sprocket 34 fixedly mounted on the rotating rod 32 and the support column 25, a chain 35 is wound around the sprocket 34, and the rotating rod 32 and the sprocket 34 on the support column 25 are connected by the chain 35. A plurality of connecting plates 36 are fixedly mounted on the liquid separation plate 26, and each group of connecting plates 36 is provided with a liquid separation groove 37. When the sliding tube 11 rotates, the inner gear ring 31 is driven to rotate, and the inner gear ring 31 is driven to rotate. The ring 31 rotates to drive the rotating rod 32 connected to the connecting gear 33 to rotate. Under the action of the sprocket 34 and the chain 35, the rotating rod 32 rotates to drive the liquid separation plate 26 connected to the support column 25 to rotate. The liquid separation plate 26 rotates to drive the connecting plate 36 to rotate. When the liquid flows to the rotating liquid separation plate through the connecting pipe 5, the liquid is diffused to the inner wall of the liquid outlet pipe 12 and the bottom plate 13 under the action of the connecting plate 36 and the liquid separation groove 37. The liquid on the inner wall of the liquid outlet pipe 12 is discharged through the liquid outlet 14 through the rotating liquid outlet pipe 12. The liquid can be sprayed evenly from the liquid outlet 14 and the reaction effect between the liquid and the flue gas is better.

[0033] Working principle: Starting the motor 41 causes the fixed rod 42 at the output end to rotate and drive the driving gear 43 to rotate. The driving gear 43 rotates and drives the sliding tube 11 connected to the outer gear ring 23 to rotate on the reciprocating screw 21, so that the sliding tube 11 drives the liquid outlet pipe 12 and the bottom plate 13 to rotate while also moving up and down, so that the bottom of the liquid separation plate 26 is in constant contact with the bottom plate 13 and the liquid in the liquid outlet pipe 12 is squeezed out through the liquid outlet 14. As the liquid outlet pipe 12 rotates, the scraper 28 also scrapes the liquid in the liquid outlet pipe 12. The wall is cleaned, and when the sliding tube 11 rotates, it drives the inner gear ring 31 to rotate, and the rotation of the inner gear ring 31 drives the rotating rod 32 connected to the connecting gear 33 to rotate. Under the action of the sprocket 34 and the chain 35, the rotating rod 32 rotates to drive the liquid separation plate 26 connected to the support column 25 to rotate, and the rotation of the liquid separation plate 26 drives the connecting plate 36 to rotate. When the liquid flows to the rotating liquid separation plate through the connecting pipe 5, the liquid is diffused to the inner wall of the liquid outlet pipe 12 and the bottom plate 13 under the action of the connecting plate 36 and the liquid separation groove 37.
