Description

Technical Field

[0001] This utility model relates to the field of wet flue gas desulfurization equipment, specifically to a spray range simulation device for hollow cone nozzles. Background Technology

[0002] As the industry matures, hollow cone nozzles are increasingly used in wet desulfurization, taking a dominant position. The spray layer, a core component of wet desulfurization equipment, typically uses steel beams as support to hold the absorption tower under the hollow cone nozzles, through which slurry is sprayed for the spraying operation.

[0003] In actual operation, it is necessary to ensure that the tower wall and support beam of the absorption tower are not within the direct spray range of the hollow cone nozzle. Otherwise, the tower wall and support beam will be easily eroded and corroded, and will cause adverse consequences such as corrosion perforation in a short period of time, which will seriously affect the structural strength of the support beam and tower wall, and may even jeopardize the safe operation of the entire desulfurization system.

[0004] Therefore, it is necessary to simulate the spray range of the hollow cone nozzle during the initial installation of the hollow cone nozzle, and assess whether the position of the tower wall and spray support beam meets the specifications. Even if the absorption tower wall and support beam are not within the direct spray range of the hollow cone nozzle, the installation angle of the hollow cone nozzle should be adjusted in time to reduce the occurrence of slurry directly spraying onto the support beam and tower wall. Utility Model Content

[0005] This application provides a spray range simulation device for hollow cone nozzles, which can solve the technical problem in the prior art where improper installation of hollow cone nozzles, due to the lack of trial operation conditions and testing methods during the early stage of installation, results in slurry directly spraying onto the tower wall and support beams during later operation, thus posing a safety hazard to the desulfurization system.

[0006] This application provides a spray range simulation device for a hollow cone nozzle, comprising:

[0007] The jet simulator includes several angle simulation rods, which are integrated at one end and radiate outwards at the other end to simulate the jet range of the hollow cone nozzle under test; the length of the angle simulation rods is much greater than the depth of the hollow cone nozzle under test.

[0008] By adopting the above technical solution, several angle simulation rods are integrated at one end for easy insertion into the hollow cone nozzle. The other ends of these rods are radially arranged to simulate the spray range of the hollow cone nozzle under test. During the installation phase of the hollow cone nozzle, inserting the spray simulator into the nozzle simulates its spray range. This allows operators to adjust the installation angle of the nozzle based on the simulated range, ensuring that the absorber tower wall and support beams are outside the direct spray range of the nozzle. This prevents direct spraying of slurry from the nozzle, solving the problem of slurry directly spraying onto the tower wall and support beams during later operation due to incorrect installation caused by a lack of trial operation conditions and testing methods during the initial installation of the hollow cone nozzle, thus posing a safety hazard to the desulfurization system.

[0009] In one embodiment, the injection simulator is provided with four angle simulation rods, and the four angle simulation rods are arranged in pairs facing each other, and the included angle between the opposing angle simulation rods is adapted to the injection angle of the hollow cone nozzle to be tested.

[0010] By adopting the above technical solution, the included angle formed between two relative angle simulation rods located on the same horizontal plane is the spray angle of the hollow cone nozzle, so as to better adapt to the spray angle of the hollow cone nozzle, so that the spray simulator can more intuitively simulate the spray range after the hollow cone nozzle is installed after being inserted into the hollow cone nozzle.

[0011] In one embodiment, the included angle between the angle simulation rods is set to 90° or 120°.

[0012] By adopting the above technical solution, in the actual use of hollow cone nozzles, the common spray angle of hollow cone nozzles is 90° or 120°. Therefore, the angle between the two relative angle simulation rods, that is, the spray angle of the spray simulator, can also be set to 90° or 120° to better adapt to the spray angle of the hollow cone nozzle.

[0013] In one embodiment, the cross-section of the angle simulation rod is set to rectangular.

[0014] By adopting the above technical solution, it is easier for operators to insert the injection simulator into the hollow cone nozzle, so that the angle simulation rod is in close contact with the edge of the hollow cone nozzle.

[0015] In one embodiment, the angle simulation rod is provided with scale lines.

[0016] By adopting the above technical solution, when the contact points of the four angle simulation rods and the hollow cone nozzle are at the same numerical position on the scale line, the center point of the integrated end of the injection simulator and the center point of the hollow cone nozzle injection point are in a coaxial state, which further reduces the operation error when the injection simulator simulates the injection range of the hollow cone nozzle.

[0017] In one implementation, it further includes:

[0018] An auxiliary balance plate is provided, and a positioning groove is provided on the auxiliary balance plate, into which the integrated end of the injection simulator can be inserted.

[0019] By adopting the above technical solution, it is possible for operators to adjust the injection simulator and the hollow cone nozzle injection point to be on the same axis.

[0020] In one embodiment, the auxiliary balance plate is further provided with a horizontal correction device.

[0021] By adopting the above technical solution, since the operator needs to hold the spray simulator and the auxiliary balance plate to simulate the spray range of the hollow cone nozzle, the horizontal correction device can help the operator adjust the auxiliary balance plate to keep it parallel to the ground, thereby reducing the possibility of movement errors of the handheld spray simulator and the auxiliary balance plate during manual operation.

[0022] In one embodiment, the horizontal correction device is configured as a horizontal bubble.

[0023] By adopting the above technical solution, the operator can adjust the position of the auxiliary balance plate to keep the horizontal bubble in a balanced state, thus keeping the auxiliary balance plate parallel to the ground, thereby reducing the movement error in the measurement. The structure is simple and easy to use.

[0024] In one embodiment, at least two horizontal bubbles are provided, and the two horizontal bubbles are arranged perpendicular to each other.

[0025] By adopting the above technical solution, the horizontal accuracy of the auxiliary balance plate can be further improved.

[0026] In one embodiment, the auxiliary balancing plate is made of a rigid material.

[0027] By adopting the above technical solution, the service life of the auxiliary balance plate is further improved, eliminating the need for frequent replacements and making it more convenient to use.

[0028] The beneficial effects of the technical solutions provided in this application include:

[0029] By integrating one end of multiple angle simulation rods together and radiating the other end to form a spray simulator, the radial end of the spray simulator can simulate the spray range of the hollow cone nozzle. During the installation phase of the hollow cone nozzle, the spray simulator is inserted into the nozzle to simulate its spray range. This allows operators to adjust the installation angle of the hollow cone nozzle according to the simulated range, ensuring that the absorber tower wall and support beams are outside the direct spray range of the nozzle. This avoids direct spraying of slurry from the nozzle, solving the problem of slurry directly spraying onto the tower wall and support beams during later operation due to incorrect installation caused by a lack of trial operation conditions and testing methods during the initial installation of the hollow cone nozzle, which poses a safety hazard to the desulfurization system.

[0033] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0034] This application provides a spray range simulation device for hollow cone nozzles, which can solve the problem of slurry directly spraying onto the tower wall and support beams during later operation due to incorrect installation caused by the lack of trial operation conditions and testing methods during the early stage of hollow cone nozzle installation, resulting in safety hazards in the desulfurization system.

[0035] Reference Figure 1This application discloses a spray range simulation device for a hollow conical nozzle 3, comprising a spray simulator 1. The spray simulator 1 includes several angle simulation rods 11, which are integrated at one end for insertion into the hollow conical nozzle 3. The other ends of the simulation rods are radially oriented and used to simulate the spray range of the hollow conical nozzle 3 under test. The length of the simulation rods is much greater than the depth of the hollow conical nozzle 3, so that after the integrated end of the spray simulator 1 is inserted into the hollow conical nozzle 3, the radial end of the spray simulator 1 can extend out of the hollow conical nozzle 3. After the hollow conical nozzle 3 is installed, the integrated end of the spray simulator 1 is inserted into the hollow conical nozzle 3. When the spray simulator 1 can no longer extend into the hollow conical nozzle 3 and the several simulation rods at the radial end of the spray simulator 1 are all in contact with the edge of the hollow conical nozzle 3, the radial end of the spray simulator 1 extends out of the hollow conical nozzle 3, and the radial shape of the several angle simulation rods 11 represents the spray range of the hollow conical nozzle 3 at this installation angle. This allows operators to visually observe the spray range of the hollow cone nozzle 3 and adjust the installation angle of the hollow cone nozzle according to the simulated range. This ensures that the tower wall and support beam below are outside the direct spray range of the hollow cone nozzle, thereby reducing the possibility that the tower wall and support beam of the absorption tower to be sprayed are directly sprayed. This solves the problem of slurry directly spraying onto the tower wall and support beam during later operation due to incorrect installation of the hollow cone nozzle in the early stage when there was a lack of trial operation conditions and testing methods, which caused safety hazards in the desulfurization system.

[0036] More specifically, in one embodiment of this application, the spray simulator 1 includes four angle simulation rods 11, which are arranged in pairs opposite each other. The included angle between two opposite angle simulation rods 11 located on the same horizontal plane is the spray angle of the hollow cone nozzle 3. During use, the included angle between two angle simulation rods 11 needs to be consistent with the spray angle of the hollow cone nozzle 3. In actual use of the hollow cone nozzle 3, the common spray angle is 90° or 120°. Therefore, the included angle between two opposite angle simulation rods 11, i.e., the spray angle of the spray simulator 1, can also be set to 90° or 120° to better adapt to the spray angle of the hollow cone nozzle 3, so that the spray simulator 1 can more intuitively simulate the spray range after the hollow cone nozzle 3 is installed. In other embodiments, the hollow cone nozzle 3 may have other spray angles; in use, it is sufficient to keep the included angle between two opposite angle simulation rods 11 consistent with the spray angle of the hollow cone nozzle 3.

[0037] In actual use, after the operator positions and initially fixes the hollow cone nozzle 3, a spray simulator 1 that matches the spray angle of the hollow cone nozzle 3 is selected, and the spray simulator 1 is inserted into the hollow cone nozzle 3 until the spray simulator 1 can no longer penetrate the hollow cone nozzle 3, and the four angle simulation rods 11 abut against the edge of the hollow cone nozzle 3. At this time, the radial range of the four angle simulation rods 11 extending from the hollow cone nozzle 3 is the spray range of the hollow cone nozzle 3 at this installation position, which makes it easier for the operator to adjust the installation position of the hollow cone nozzle 3.

[0038] To make it easier for operators to determine whether the injection simulator 1 is fully inserted into the hollow cone nozzle 3, the angle simulation rod 11 is also equipped with scale lines. When the contact points of the four angle simulation rods 11 and the hollow cone nozzle 3 are at the same value position on the scale line, the center point of the integrated end of the injection simulator 1 and the center point of the injection point of the hollow cone nozzle 3 are in a coaxial state, which further reduces the operation error when the injection simulator 1 simulates the injection range of the hollow cone nozzle 3.

[0039] Furthermore, the cross-section of the angle simulation rod 11 can be set to a rectangle to facilitate the operator in ensuring that the angle simulation rod 11 fits snugly against the edge of the hollow cone nozzle 3 after inserting the injection simulator 1 into it. In other embodiments, the cross-section of the angle simulation rod 11 can also be set to a circle according to the actual processing conditions; the specific shape can be flexibly changed according to actual needs.

[0040] To further facilitate operators in adjusting the coaxial alignment of the injection simulator 1 and the hollow cone nozzle 3, this injection range simulation device also includes an auxiliary balance plate 2. The auxiliary balance plate 2 has a positioning groove 21, the shape of which is set according to the number of angle simulation rods 11, so that the integrated end of the injection simulator 1 can pass through the positioning groove 21 and be inserted into the hollow cone nozzle 3. In use, the auxiliary balance plate 2 is placed tightly against the opening of the hollow cone nozzle 3, and the integrated end of the injection simulator 1 is inserted into the hollow cone nozzle 3 through the positioning groove 21. This ensures that the insertion direction of the injection simulator 1 is parallel to the axis of the hollow cone nozzle 3, making it more convenient to use.

[0041] Reference Figure 1 In a more detailed embodiment of this application, when four angle simulation rods 11 are provided and the hollow cone nozzle 3 to be tested is 90°, the positioning groove 21 on the auxiliary balance plate 2 is opened as a cross groove. The cross groove can assist the injection simulator 1 to be vertically inserted into the hollow cone nozzle 3, making it more convenient to use.

[0042] Furthermore, since the operator needs to hold the spray simulator 1 and the auxiliary balance plate 2 to perform simulated measurements when simulating the spray range of the hollow cone nozzle 3, in order to reduce the possibility of movement errors in the handheld spray simulator 1 and the auxiliary balance plate 2 during manual operation, a horizontal correction device is also provided on the auxiliary balance plate 2 to help the operator adjust the auxiliary balance plate 2 to keep it parallel to the ground.

[0043] The horizontal correction device is specifically configured as a horizontal bubble 22. The operator adjusts the position of the auxiliary balance plate 2 to ensure the horizontal bubble 22 is in a balanced state, thus maintaining the auxiliary balance plate 2 parallel to the ground and reducing movement errors during measurement. The device is simple in structure and easy to use. At least two horizontal bubbles 22 are provided; in one embodiment of this application, four horizontal bubbles 22 are specifically provided, with adjacent horizontal bubbles 22 positioned perpendicularly to each other. Each horizontal bubble 22 is located at one of the four corners of the auxiliary balance plate 2 to further improve the horizontal accuracy of the auxiliary balance plate 2. Simultaneously, by providing multiple horizontal bubbles 22, the operator can also use the auxiliary balance plate 2 individually to measure the horizontal position of the opening of the hollow conical nozzle 3. The auxiliary balance plate 2 is attached to the opening of the hollow conical nozzle 3. If all the horizontal bubbles 22 on the auxiliary balance plate 2 are in a balanced state, it indicates that the opening of the hollow conical nozzle 3 is parallel to the ground, meaning the nozzle axis of the hollow conical nozzle 3 is perpendicular to the ground. Combined with the spray angle of the hollow conical nozzle 3, the installation position of the hollow conical nozzle 3 is also corrected.

[0044] More specifically, in order to further extend the service life of the auxiliary balance plate 2, the auxiliary balance plate 2 is made of rigid materials, such as steel, which have good rigidity and strength, so that it does not need to be replaced frequently and is more convenient to use.
