Description

Technical Field

[0001] This utility model relates to the field of soot blowing equipment technology, specifically an array-type resonant cavity intelligent acoustic soot blower. Background Technology

[0002] When the flue gas from the lower part of the boiler's flame deflector enters the upper part of the horizontal flue, the reduced flue gas velocity and backflow cause most of the fly ash to accumulate on the slope of the flame deflector. Ash accumulation on the slope of the flame deflector affects heat exchange efficiency. Frequent ash collapse in the boiler leads to negative pressure in the furnace, seriously affecting the safe operation of the unit. Traditional steam sootblowers have a small blowing range, high air consumption, and are prone to damaging the heat exchange surfaces. Some acoustic sootblowers can only be installed on the furnace wall, resulting in incomplete blowing inside the furnace and low sound power, leading to poor blowing effect. Therefore, we designed an array-type resonant cavity intelligent acoustic sootblower with a large blowing range, high sound power, high intelligence, and low air consumption to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to overcome or at least partially solve the above problems by proposing an array-type resonant cavity intelligent acoustic soot blower.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: an array-type resonant cavity intelligent acoustic soot blower, comprising an air source pipe, a first connecting pipe and a second connecting pipe connected in sequence, and a support frame. The second connecting pipe is rotatably mounted in the support frame. Multiple resonant cavity acoustic soot blowers are arrayed on the outer wall of the second connecting pipe. The second connecting pipe and the first connecting pipe are rotatably connected together. One end of the outer wall of the second connecting pipe is provided with a drive assembly that enables the second connecting pipe to rotate and drive the resonant cavity acoustic soot blowers to flip.

[0005] In a preferred embodiment, the drive assembly includes a driven sprocket, a chain, a drive sprocket, and a motor. The driven sprocket is disposed at one end of the outer wall of the second connecting pipe, the drive sprocket is disposed at the output end of the motor, and the chain meshes with the outer walls of the driven sprocket and the drive sprocket.

[0024] This utility model discloses an array-type resonant cavity intelligent acoustic soot blower, which solves the technical problems in the prior art. The overall concept is as follows:

[0025] Example 1:

[0026] Please see Figure 1 , Figure 2An array-type resonant cavity intelligent acoustic soot blower includes an air source pipe 1, a first connecting pipe 3, and a second connecting pipe 11 connected in sequence, as well as a support frame 9. The second connecting pipe 11 is rotatably disposed in the support frame 9. Multiple resonant cavity acoustic soot blowers 12 are arrayed on the outer wall of the second connecting pipe 11. The second connecting pipe 11 is rotatably connected to the first connecting pipe 3. One end of the outer wall of the second connecting pipe 11 is provided with a drive assembly that enables the second connecting pipe 11 to rotate and drive the resonant cavity acoustic soot blowers 12 to flip.

[0027] In specific implementation, the drive assembly includes a driven sprocket 5, a chain 6, a driving sprocket 7, and a motor 8. The driven sprocket 5 is located at one end of the outer wall of the second connecting pipe 11, and the driving sprocket 7 is located at the output end of the motor 8. The chain 6 meshes with the outer walls of the driven sprocket 5 and the driving sprocket 7. The motor 8 drives the driving sprocket 7 to rotate, which can drive the driven sprocket 5 and the second connecting pipe 11 to rotate through the chain 6, thereby causing the resonant cavity acoustic soot blower 12 to flip to the other side.

[0028] In practice, the diameter of the driving sprocket 7 is smaller than that of the driven sprocket 5 in order to slow down the rotation speed of the resonant cavity acoustic soot blower 12.

[0029] In specific implementation, the first connecting pipe 3 and the second connecting pipe 11 are connected together through a rotating interface 4, which facilitates the rotation of the second connecting pipe 11 to connect with the first connecting pipe 3.

[0030] In practice, the support frame 9 is arranged in a concave shape with open front, back, sides and top, and the sides are triangular. This arrangement ensures that the rotation of the resonant cavity acoustic soot blower 12 is not affected, while minimizing the space occupied by the support frame 9.

[0031] In practice, the first connecting pipe 3 is set in an "L" shape. Depending on actual needs, it can also be other suitable shapes, such as a "Z" shape, to facilitate the connection between the gas source pipe 1 and the second connecting pipe 11.

[0032] In practice, a solenoid valve 2 is installed between the gas source pipeline 1 and the first connecting pipeline 3.

[0033] In practice, the resonant cavity intelligent acoustic sootblower is mainly installed in two areas: inside and outside the furnace. The array-type resonant cavity intelligent acoustic sootblower and its installed components in the furnace area are all made of high-temperature alloy materials, which will not affect the sootblowing equipment during boiler operation.

[0034] In practical implementation, the array-type resonant cavity intelligent acoustic sootblower also includes an intelligent control system. The intelligent control system includes a host computer, a PLC, and a thermal sensor. The thermal sensor transmits the temperature data of the water-cooled wall and the heater to the PLC. The PLC transmits the temperature data to the host computer for intelligent analysis. The host computer transmits the analyzed temperature data back to the PLC. The PLC transmits action commands to the solenoid valve 2 and the motor 8 for control. The PLC controls the duration of sootblowing by controlling the opening duration of the solenoid valve. The PLC changes the direction of sootblowing by controlling the start, stop, forward rotation, and reverse rotation of the AC motor.

[0035] In practice, the intelligent control system analyzes and diagnoses the thermal deviation state of each area inside the boiler by real-time intelligent analysis of water-cooled wall and heater data. Then, based on the thermal deviation state of the corresponding areas before and after soot blowing, it determines the area, time and duration of ash removal, so as to achieve precise ash removal inside the boiler and ash removal on demand, which can greatly reduce the use of steam.

[0036] Its detailed connection methods are well-known technologies in this field. The following mainly introduces the working principle and process, and the specific work is as follows:

[0037] In use, the air supply pipe 1 is connected to the air source to supply air to the entire equipment. After the solenoid valve 2 is opened, the high-pressure airflow passes through the first connecting pipe 3, then through the rotary interface 4, and then is transmitted to the second connecting pipe 11, and finally distributed to the array-type resonant cavity acoustic sootblower. The array-type resonant cavity acoustic sootblower consists of multiple resonant cavity acoustic sootblowers arranged in a row, which greatly increases the sootblowing range and improves the power of the sootblowing sound waves.

[0038] The array-type resonant cavity intelligent acoustic sootblower can remove ash in both directions. Since the sound waves are directional after propagation through the horn, the array-type resonant cavity intelligent acoustic sootblower is installed in the middle area of ​​the furnace. After the ash removal on one side of the furnace is completed, the motor 8 is controlled to drive the drive sprocket 7 to rotate, which in turn drives the chain 6 to rotate, which in turn drives the driven sprocket 5 to rotate. Finally, the second connecting pipe 11 is rotated, and then the resonant cavity acoustic sootblower 12 is flipped to the other side to remove ash from the other side of the furnace.

[0039] The above description of the embodiments is provided to facilitate understanding and use of the present invention by those skilled in the art. It is obvious to those skilled in the art that various modifications can be made to the embodiments, and the general principles described herein can be applied to other embodiments without creative effort. Therefore, the present invention is not limited to the above embodiments. Any improvements and modifications made by those skilled in the art based on the disclosure of the present invention without departing from the scope of the present invention should be within the protection scope of the present invention.
