Description

Technical Field

[0002] The soot blowing system of a low-low temperature economizer (also known as a low temperature economizer or a low pressure economizer) is a key equipment maintenance system, aiming to remove the ash deposited on the heating surface to ensure the safe and economic operation of the boiler. During the operation of the low-low temperature economizer, serious ash deposition occurs, resulting in an increase in resistance and a decrease in heat transfer efficiency. Moreover, serious ash deposition will lead to a decline in equipment performance, which poses higher requirements for soot blowing technology.

[0003] The existing steam soot blowing technology uses steam soot blowers that are difficult to effectively remove ash, and it also exacerbates equipment wear. Especially in equipment with a special structure like the low-low temperature economizer, the steam soot blowing effect is limited.

Therefore, there is an urgent need to design a soot blowing device and system to solve problems such as the increased resistance and decreased heat transfer efficiency caused by ash deposition on the heat exchange elements of the low-low temperature economizer, to achieve an efficient, economic, and environmentally friendly cleaning method, improve the overall operation efficiency, and extend the service life of the low-low temperature economizer.

The terminal block 35 is electrically connected to the electromagnetic oscillator 10.

[0038] The working principle and beneficial effects of the above technical solution are as follows:

[0039] The soot blowing device of the present invention includes adjusting the soot blowing position of the soot blowing mechanism through the adjusting mechanism 3, and the electromagnetic modulation mechanism 4 cooperates with the sound wave generator 5 to complete soot blowing on the device to be soot blown by the soot blowing mechanism. The fixing mechanism 8 provides reliable support for the soot blowing mechanism during the soot blowing process. The intelligent control module 9 can control the special structure and ash accumulation characteristics of the low-low economizer 18 by the soot blowing device to provide more efficient cleaning. A plurality of universal wheels 13 are fixedly installed on the peripheral side of the bottom of the mounting plate 1, which is convenient for the movement of the soot blowing device to the working position. At the same time, the limiting block 14 is fixedly installed on the top of the mounting plate 1, which is convenient for limiting the initial position of the soot blowing mechanism on the mounting bracket 2. The electromagnetic modulation mechanism 4 includes an electromagnetic oscillator 10, a modulator 11 and an amplifier 12. The electromagnetic oscillator 10 is one of the core devices of electromagnetic modulation technology. It can convert direct current electrical energy into alternating current electrical energy and generate a high-frequency oscillating electromagnetic field. This high-frequency oscillating electromagnetic field is the basis for the subsequent generation of sound waves. The modulator 11 is used to load information signals (such as audio, video, etc.) onto the high-frequency carrier signal. In electromagnetic modulation technology, the role of the modulator 11 is to convert low-frequency signals (such as sound wave signals) into high-frequency signals to reduce attenuation and interference during transmission. The amplifier 12 is used to enhance the intensity of the electromagnetic signal. During the electromagnetic modulation process, the amplifier 12 can amplify the high-frequency signal generated by the electromagnetic oscillator 10 to ensure that it can drive the sound wave generator 5 to generate sufficient sound wave energy. The above electromagnetic modulation mechanism 4 uses the action of the electromagnetic field to cause the diaphragm or oscillator and other structures of the sound wave generator 5 to vibrate, and then generate resonance in the resonance cavity to form sound waves to drive the sound wave generator 5 to perform soot blowing.

[0040] The soot blowing mechanism includes a connecting elbow 15, a connecting pipe 16 and a soot blowing pipe 17. The sound waves generated by the sonic soot blower are conveyed into the soot blowing pipe 17 through the provided connecting elbow 15 and connecting pipe 16. Since the soot blowing pipe 17 is designed in a horn shape, the sound waves are further amplified, ensuring effective cleaning of the ash accumulation on the internal components of the low-low economizer 18. Secondly, the fixing mechanism 8 includes a fixing sleeve 19 and a sliding rod 3220. The sliding rod 3220 is slidably connected in the fixing sleeve 19 through a spring 22. The lower end of the sliding rod 3220 slidably penetrates the bottom of the fixing sleeve 19 and is fixedly installed with a mounting ring 21. A buffer ring 23 is arranged on the inner wall of the mounting ring 21, and the mounting ring 21 is sleeved on the connecting elbow 15. When the soot blowing mechanism shakes during the soot blowing process, it can provide reliable buffering and effective support to prevent the soot blowing mechanism from detaching from the device being soot blown. The spring 22 sleeved on the sliding rod 3220 can ensure that the sliding rod 3220 always remains in the initial position by relying on its elastic force.

[0041] Through the provided adjustment mechanism 3, when it is necessary to adjust the working position of the soot blowing mechanism, the driving motor 25 is started at this time. The forward and reverse rotation of the driving motor 25 can achieve the up and down adjustment of the soot blowing mechanism. The output shaft of the driving motor 25 rotates through the side wall of the box body 26 and is fixedly installed with a first bevel gear 27, so that the first bevel gear 27 rotates synchronously. The two ends of the threaded rod 28 are respectively rotatably connected to the top and bottom inside the box body 26. A second bevel gear 29 is fixedly installed at the lower part of the threaded rod 28. The second bevel gear 29 is meshed with the first bevel gear 27 for transmission, so that the threaded rod 28 rotates synchronously. A threaded sleeve 30 is threadedly connected to the threaded rod 28. The threaded sleeve 30 is fixedly connected to the side wall of the mounting bracket 2 through a connecting rod 31. The threaded sleeve 30 threadedly connected to the threaded rod 28 can drive the mounting bracket 2 connected through the connecting rod 31 to move up and down with the forward and reverse rotation of the threaded rod 28. And the slide rod 3220 fixedly connected to the side wall of the mounting bracket 2 slides up and down along the guide post, providing reliable support for the mounting bracket 2.

[0042] The above-mentioned soot blowing device introduces high-intensity acoustic soot blowing technology, and uses electromagnetic modulation to ensure that the acoustic frequency and intensity can not only effectively remove ash but also will not damage the equipment. This technology can provide a more efficient cleaning solution for the special structure and ash accumulation characteristics of the low-low temperature economizer 18; at the same time, it solves the problems such as the increase in resistance and the decrease in heat transfer efficiency caused by the ash accumulation of the heat exchange elements of the low-low temperature economizer 18, realizes an efficient, economical and environmentally friendly cleaning method, improves the overall operation efficiency, and prolongs the service life of the low-low temperature economizer 18.

At the same time, this soot blowing system can penetrate deep into the pipeline and equipment interior by using acoustic vibration to thoroughly remove the accumulated ash and dirt; secondly, compared with the traditional soot blowing method, the electromagnetic modulation soot blowing system does not require a large amount of steam or compressed air, so the energy consumption is lower and no secondary pollution will be generated; the automation degree of this system is high, the operation is simple, and the labor maintenance cost is reduced; and this soot blowing system can adapt to different application scenarios and equipment types with different types of electromagnetic modulation combined with the acoustic wave generator 5, and has strong flexibility; simple operation: the automation degree of the system is high, the operation is simple, and the labor maintenance cost is reduced.
