Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of auxiliary facilities for waste power plants, and specifically relates to an atomizer for waste power plants which is convenient for maintenance. Background Technique
[0002] Waste incineration power plants utilize the heat generated by waste incineration. Then, water is heated and vaporized by the heat, and then steam is used to drive the steam turbine to operate in cooperation with the generator for power generation. During the waste incineration process, a large amount of toxic and harmful gases are generated. Direct emission of these gases will pollute the atmosphere. Therefore, waste gas needs to be treated. Among them, the deacidification of waste gas generally uses a rotary atomizer to generate centrifugal force by high-speed rotation, and then the lime slurry is atomized and sprayed out by the centrifugal force. Then, the lime slurry droplets contact the waste gas to produce a chemical reaction, thereby removing acidic substances in the flue gas.
[0003] For the existing atomizer used in waste power plants, since it atomizes lime slurry, the lime slurry is very easy to scale in the atomization disk, which leads to blockage of the spray nozzle of the atomization disk and affects the atomization effect. It requires the staff to disassemble and brush it, which is time-consuming and laborious. Content of the Utility Model
[0004] Based on this, the purpose of the utility model is to provide an atomizer for waste power plants which is convenient for maintenance, so as to solve the technical problems mentioned in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: an atomizer for waste power plants which is convenient for maintenance, including a fixed frame and a transmission shaft. A bolt penetrates through the bottom of the transmission shaft. An atomization disk is sleeved outside the transmission shaft. An adjusting frame is connected inside the atomization disk. Spray nozzles are opened on the outer surfaces of the adjusting frame and the atomization disk. Limiting teeth are arranged at the top of the atomization disk and the bottom of the adjusting frame. A slip ring penetrates through the bottom of the fixed frame.
[0006] By adopting the above technical solution, when the spray openings on the centrifugal disk are blocked, loosen the bolts and move the adjusting frame away from the centrifugal disk. At this time, the limiting teeth on both of them are separated. Then rotate the adjusting frame or the centrifugal disk to adjust the included angle of the spray openings on both of them, so that the spray openings on the centrifugal disk are completely aligned with the spray openings on the adjusting frame, thereby increasing the diameter of the spray openings. After that, fit the adjusting frame and the centrifugal disk together, and prevent them from rotating towards each other through the engagement of the limiting teeth on both of them, so as to avoid relative movement between the centrifugal disk and the adjusting frame during high-speed rotation. Then tighten the bolts so that the top of the adjusting frame abuts against the slip ring, and the bolts abut against the bottom of the centrifugal disk, clamping the adjusting frame and the centrifugal disk together to prevent relative movement in the vertical direction between the two from causing the separation of the limiting teeth. And through the setting of the slip ring, it is avoided that the adjusting frame wears greatly against the fixed frame when following the centrifugal disk to rotate at high speed. At this time, when the atomizer is started again, since the diameter of the spray openings becomes larger, it is convenient to flush out and throw out the previously blocked lime scale in the spray openings. After the cleaning is completed, loosen the bolts again to adjust the adjusting frame back to its original position to reduce the diameter of the spray openings for atomizing the lime slurry, and the diameter can be adjusted to be larger or smaller to adjust the size of the lime slurry droplets.
[0007] Further, the bolt is threadedly connected to the transmission shaft and abuts against the centrifugal disk.
[0008] By adopting the above technical solution, the staff tightens the bolts so that the top of the adjusting frame abuts against the slip ring, and the bolts abut against the bottom of the centrifugal disk, clamping the adjusting frame and the centrifugal disk together to prevent relative movement in the vertical direction between the two from causing the separation of the limiting teeth.
[0009] Further, the adjusting frame is rotatably connected to the centrifugal disk.
[0010] By adopting the above technical solution, the staff rotates the adjusting frame or the centrifugal disk to adjust the included angle of the spray openings on both of them, so that the spray openings on the centrifugal disk are completely aligned with the spray openings on the adjusting frame, thereby increasing the diameter of the spray openings.
[0011] Further, the limiting teeth at the top of the centrifugal disk abut against the limiting teeth at the bottom of the adjusting frame, and the adjusting frame abuts against the slip ring.
[0012] By adopting the above technical solution, the engagement of the limiting teeth on both of them prevents them from rotating towards each other, thereby avoiding relative movement between the centrifugal disk and the adjusting frame during high-speed rotation.
[0013] Further, the cross-section of the slip ring is in a "T" shape, and the slip ring is rotatably connected to the fixed frame.
[0014] By adopting the above technical solution, through the setting of the slip ring, it is avoided that the adjusting frame wears greatly against the fixed frame when following the centrifugal disk to rotate at high speed, and the "T" shape of the slip ring can prevent the slip ring from falling off the fixed frame.
[0015] Furthermore, a motor is installed on the outer surface of the fixing frame, and the transmission shaft is connected to the output end of the motor. An inlet for slurry is provided on one side of the top of the fixing frame.
[0016] By adopting the above technical solution, the staff connects the pipeline for conveying lime slurry to the inlet for slurry. Then, the staff starts the motor. After the motor starts, the output end drives the transmission shaft to rotate. Since one end of the transmission shaft is in a plum blossom shape, it is convenient to transmit torque to drive the centrifugal disc to rotate. The rotation of the centrifugal disc drives the adjusting frame to rotate through the limit teeth. At the same time, the lime slurry passes through the inlet for slurry and enters the centrifugal disc. The lime slurry is broken into droplets and thrown out by the centrifugal force generated by the high-speed rotation of the centrifugal disc in cooperation with the spray orifice.
[0017] Furthermore, the cross-section of one end of the transmission shaft is in a plum blossom shape.
[0018] By adopting the above technical solution, after the motor starts, the output end drives the transmission shaft to rotate. Since one end of the transmission shaft is in a plum blossom shape, it is convenient to transmit torque to drive the centrifugal disc to rotate.
[0019] Furthermore, a first guiding slope and a second guiding slope are respectively arranged on the inner ring of the adjusting frame, and there are multiple second guiding slopes. The multiple second guiding slopes are distributed in an annular array.
[0020] By adopting the above technical solution, the lime slurry is guided by the first guiding slope and the second guiding slope, which is more convenient for the lime slurry to flow towards the spray orifice when subjected to centrifugal force.
[0021] In summary, the main beneficial effects of the present utility model are as follows:
[0022] In this utility model, through the settings of bolts, adjusting frames, spray nozzles, slip rings and limit teeth, when the spray nozzles on the centrifugal disk are blocked, loosen the bolts and move the adjusting frame away from the centrifugal disk. At this time, the limit teeth on the two separate. Then rotate the adjusting frame or the centrifugal disk to adjust the included angle of the spray nozzles on the two, so that the spray nozzles on the centrifugal disk are completely aligned with the spray nozzles on the adjusting frame, thereby increasing the caliber of the spray nozzles. Then fit the adjusting frame and the centrifugal disk together, and prevent the two from rotating towards each other through the mutual engagement of the limit teeth on the two, so as to avoid relative movement between the centrifugal disk and the adjusting frame during high-speed rotation. Then tighten the bolts so that the top of the adjusting frame abuts against the slip ring, and the bolts abut against the bottom of the centrifugal disk, clamping the adjusting frame and the centrifugal disk together to prevent relative movement in the vertical direction between the two from causing the separation of the limit teeth. And through the setting of the slip ring, it is avoided that the adjusting frame wears greatly with the fixed frame during high-speed rotation following the centrifugal disk. At this time, when the atomizer is started again, since the caliber of the spray nozzles becomes larger, it is convenient to flush out and throw out the previously blocked lime scale in the spray nozzles. After cleaning, loosen the bolts again to adjust the adjusting frame back to its original position to reduce the caliber of the spray nozzles, so as to atomize the lime slurry, and the caliber can be adjusted to be larger or smaller to adjust the size of the lime slurry droplets; by increasing the caliber of the spray nozzles, it is convenient to flush out and throw out the lime scale, without the need to completely disassemble and clean, the operation is simple and fast, and the size of the spray nozzles can be adjusted to facilitate the adjustment of the droplet size, increasing flexibility.

[0028] Next, the technical solutions in the embodiments of this utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this utility model. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as a limitation to this utility model.
[0029] The following is an illustration of the embodiments of the overall structure of the present utility model.
[0030] Embodiment 1:
[0031] An atomizer for a waste power plant that is convenient for maintenance, as Figures 1-4 shown, includes a fixing frame 1 and a transmission shaft 4. A bolt 5 penetrates through the bottom of the transmission shaft 4. The bolt 5 is threadedly connected to the transmission shaft 4 and abuts against the centrifugal disc 6. Tighten the bolt 5 so that the top of the adjusting frame 7 abuts against the slip ring 9, and the bolt 5 abuts against the bottom of the centrifugal disc 6, sandwiching the adjusting frame 7 and the centrifugal disc 6 together; the centrifugal disc 6 is sleeved outside the transmission shaft 4, and an adjusting frame 7 is connected inside the centrifugal disc 6. The adjusting frame 7 is rotatably connected to the centrifugal disc 6. Spray ports 8 are provided on the outer surfaces of both the adjusting frame 7 and the centrifugal disc 6. Rotate the adjusting frame 7 or the centrifugal disc 6 to adjust the included angle of the spray ports 8 on the two, so that the spray ports 8 on the centrifugal disc 6 are completely corresponding to the spray ports 8 on the adjusting frame 7, thereby increasing the diameter of the spray ports 8; limiting teeth 10 are provided at the top of the centrifugal disc 6 and the bottom of the adjusting frame 7. The limiting teeth 10 at the top of the centrifugal disc 6 abut against the limiting teeth 10 at the bottom of the adjusting frame 7. The mutual engagement of the limiting teeth 10 on the two prevents the two from rotating towards each other, thereby preventing relative movement between the centrifugal disc 6 and the adjusting frame 7 during high-speed rotation; a slip ring 9 penetrates through the bottom of the fixing frame 1, and the adjusting frame 7 abuts against the slip ring 9. The cross-section of the slip ring 9 is in a "T" shape, and the slip ring 9 is rotatably connected to the fixing frame 1. Through the setting of the slip ring 9, it is avoided that the adjusting frame 7 and the fixing frame 1 generate large wear during high-speed rotation following the centrifugal disc 6.
[0032] Refer to Figure 1 、 Figure 2 and Figure 4 , in the above embodiment, a motor 2 is installed on the outer surface of the fixing frame 1. The transmission shaft 4 is connected to the output end of the motor 2. The cross-section of one end of the transmission shaft 4 is in a plum blossom shape. After the motor 2 is started, the output end drives the transmission shaft 4 to rotate. Since one end of the transmission shaft 4 is in a plum blossom shape, it is convenient to transmit torque to drive the centrifugal disc 6 to rotate; a slurry inlet 3 is provided on one side of the top of the fixing frame 1. Connect the pipeline for transporting lime slurry to the slurry inlet 3, so that the lime slurry passes through the slurry inlet 3 and enters the centrifugal disc 6.
[0033] Embodiment 2:
[0034] On the basis of the above Embodiment 1, in order to facilitate the entry of lime slurry into the spray ports 8, the following settings are now made.
[0035] Refer to Figure 2 and Figure 4, in the above embodiment, a first guiding slope 11 and a second guiding slope 12 are respectively arranged on the inner ring of the adjusting frame 7. There are multiple second guiding slopes 12, and the multiple second guiding slopes 12 are distributed in an annular array. The first guiding slope 11 and the second guiding slope 12 are used to guide the flow of lime slurry, making it more convenient for the lime slurry to flow towards the spray port 8 when subjected to centrifugal force.
[0036] The implementation principle of the present utility model is as follows: First, the staff connects the pipeline for transporting lime slurry to the slurry inlet 3. Then, the staff turns on the motor 2. After the motor 2 starts, the output end drives the transmission shaft 4 to rotate. Since one end of the transmission shaft 4 is in a plum blossom shape, it is convenient to transmit torque to drive the centrifugal disk 6 to rotate. The rotation of the centrifugal disk 6 drives the adjusting frame 7 to rotate through the limiting teeth 10. At the same time, the lime slurry passes through the slurry inlet 3 and enters the centrifugal disk 6. The centrifugal force generated by the high-speed rotation of the centrifugal disk 6 cooperates with the spray port 8 to disperse the lime slurry into mist droplets and throw them out. At the same time, the first guiding slope 11 and the second guiding slope 12 are used to guide the flow of lime slurry, making it more convenient for the lime slurry to flow towards the spray port 8 when subjected to centrifugal force;
[0037] When the spray port 8 on the centrifugal disk 6 is blocked, the staff first turns off the motor 2. Then, the staff loosens the bolt 5 and moves the adjusting frame 7 away from the centrifugal disk 6 in the vertical direction to separate the limiting teeth 10 on the two. Then, the staff rotates the adjusting frame 7 or the centrifugal disk 6 to adjust the included angle of the spray ports 8 on the two, so that the spray port 8 on the centrifugal disk 6 completely corresponds to the spray port 8 on the adjusting frame 7, thereby increasing the diameter of the spray port 8;
[0038] After adjustment, the staff fits the adjusting frame 7 with the centrifugal disk 6, and the limiting teeth 10 on the two are engaged with each other to prevent the two from rotating towards each other, thereby preventing relative movement between the centrifugal disk 6 and the adjusting frame 7 during high-speed rotation. Then, the staff tightens the bolt 5 so that the top of the adjusting frame 7 abuts against the slip ring 9, and the bolt 5 abuts against the bottom of the centrifugal disk 6, clamping the adjusting frame 7 and the centrifugal disk 6 together to prevent relative movement between the two in the vertical direction, resulting in the separation of the limiting teeth 10. And through the setting of the slip ring 9, it is avoided that the adjusting frame 7 generates excessive wear with the fixed frame 1 when following the centrifugal disk 6 to rotate at high speed;
[0039] After fastening the structure, the staff starts the motor 2 again. Since the diameter of the spray port 8 becomes larger, it is convenient to flush out and throw out the lime scale previously blocked in the spray port 8. After cleaning, the staff loosens the bolt 5 again to adjust the adjusting frame 7 back to its original position to reduce the diameter of the spray port 8, so as to atomize the lime slurry, and the diameter can be adjusted to be larger or smaller to adjust the size of the lime slurry mist droplets.
[0040] Although embodiments of the present utility model have been shown and described, the specific embodiments are only explanations of the present utility model and not limitations thereof. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions and variations without creative contributions to the embodiments as needed, but as long as they are within the scope of the claims of the present utility model, they are protected by the patent law.
