Description

Technical Field

[0001] This invention relates to the field of industrial cleaning equipment technology, specifically to a novel high-frequency high-pressure acoustic soot blower. Background Technology

[0002] In industrial production and the energy sector, ash accumulation in boiler equipment has always been a significant factor affecting equipment operating efficiency and safety. Traditional high-pressure steam soot blowers remove ash by directly flushing the surface of the heat exchanger with high-temperature, high-pressure steam. Their core principle is to use the momentum of the steam jet to mechanically impact the dust and achieve ash removal.

[0003] However, existing soot blowers suffer from significant attenuation of the steam flow's impact force at the end, leading to severe localized ash accumulation and creating dead zones for cleaning. This makes it difficult to uniformly remove ash and slag from complex heating surfaces, affecting the boiler's subsequent operation. Summary of the Invention

[0004] To address the aforementioned shortcomings in existing technologies, this invention provides a novel high-frequency, high-pressure acoustic sootblower. This addresses the problem that existing sootblowers suffer from significant attenuation of steam flow impact at the end, leading to severe localized ash accumulation, creating cleaning dead zones, and making it difficult to uniformly remove ash and slag from complex heating surfaces, thus affecting subsequent boiler operation.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A novel high-frequency, high-pressure acoustic soot blower includes a base with an acoustic horn fixedly connected to its bottom surface; a cover plate fixedly installed on the top surface of the base, a vibration chamber provided at the connection between the base and the cover plate, the vibration chamber being rhomboid in shape, with both ends of the vibration chamber extending downward to form a connecting cavity, the acoustic horn communicating with the vibration chamber; a titanium diaphragm disposed inside the vibration chamber; and an air inlet adapter fixedly installed on the side of the base, the air inlet adapter communicating with the connecting cavity.

[0006] In this way, when it is necessary to remove the ash from the boiler equipment, the air inlet adapter is connected to an external compressed air source. The compressed air enters the vibration chamber through the connecting cavity. The titanium diaphragm is located between the cover plate and the base. Under the action of the compressed air, it generates high-frequency vibration, thereby generating high-frequency and high-pressure sound waves. After the sound waves are amplified by the sound wave horn, they couple to form a standing wave field during propagation and trigger a chain resonance. This applies a high-acceleration peeling action and vibration fatigue crushing action to the ash in the boiler equipment, causing it to loosen and fall off. With this structure, the ash inside the boiler can be effectively removed, reducing the possibility of local ash removal forming the four corners of the ash. At the same time, the sound wave ash removal does not directly act on the metal surface, thereby reducing the possibility of wear on the equipment surface.

[0007] Furthermore, the top surface of the cover plate has symmetrically opened exhaust holes, which are connected to the vibration chamber.

[0008] In this way, excess compressed gas can be discharged through the exhaust port, maintaining the pressure balance inside the sootblower. This structure ensures smooth gas flow and reduces the possibility of pressure fluctuations inside the sootblower caused by airflow turbulence.

[0009] Furthermore, a compression ring is provided between the titanium diaphragm and the cover plate, which can improve the sealing performance between the titanium diaphragm and the cover plate and reduce the possibility of gas leakage.

[0010] Furthermore, the compression ring is made of rubber, which can act as a buffer and reduce the possibility of damage to the titanium diaphragm and the cover plate due to mutual friction.

[0011] Furthermore, the titanium diaphragm is made of titanium alloy material, which improves the high temperature and high pressure resistance of the titanium diaphragm.

[0012] Furthermore, the thickness of the titanium diaphragm is 0.2 mm to 0.5 mm, which facilitates the titanium diaphragm to generate high-frequency vibration under the action of compressed air, thereby generating high-frequency and high-voltage sound waves.

[0013] Furthermore, the acoustic horn is made of stainless steel, which improves its strength and corrosion resistance, thereby enhancing its stability under high temperature and high pressure conditions.

[0014] Furthermore, the air inlet adapter is equipped with a filter, which reduces impurities and moisture carried in the compressed air, thereby reducing the possibility of damage to the titanium diaphragm. Attached Figure Description

Detailed Implementation

[0016] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0017] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0018] Example: like Figures 1-2 As shown, a novel high-frequency, high-pressure acoustic sootblower of the present invention includes a base 1 with bolt pre-drilled holes on its top surface. A cover plate 2 is fixedly connected to the base 1 via bolts that mate with the pre-drilled holes. A vibration chamber 201 is formed at the connection between the base 1 and the cover plate 2, and a titanium diaphragm 3 is disposed inside the vibration chamber 201. The titanium diaphragm 3 is made of high-purity titanium alloy material with a thickness of 0.2 mm to 0.5 mm. Specifically, the standard GB / T 3621-2007 specifies the high-purity titanium alloy material. The titanium diaphragm 3 can withstand a temperature of 300℃ and a pressure of 1.5 MPa.

[0019] The top surface of the cover plate 2 has symmetrically opened exhaust holes 5, which are connected to the vibration chamber 201. A compression ring 6 is provided between the titanium diaphragm 3 and the cover plate 2. The compression ring 6 is made of high temperature and high pressure resistant rubber material. Specifically, the standard T / TLRIA 0002-2017 specifies the high temperature and high pressure resistant rubber material, and the elastic modulus of the compression ring 6 is within the range of 10MPa to 20MPa.

[0020] The vibration chamber 201 extends downward at both ends to form a connecting chamber 202. An air inlet adapter 4 is fixedly installed on the side of the base 1. The air inlet adapter 4 is connected to the connecting chamber 202. The air inlet adapter 4 is equipped with multiple layers of filter screens.

[0021] A sonic horn 101 is fixedly connected to the bottom surface of the base 1. The sonic horn 101 adopts a multi-segment structure, with each module connected by a flange. The vibration chamber 201 has an overall rhomboid structure. This diagonal design makes... When sound waves are reflected inside the cavity, they gradually concentrate towards the central area along the diagonal direction, forming a higher energy density inside the cavity. Under the same input power, stronger vibrations or sound field outputs can be generated.

[0022] According to computer simulations, the sound wave, after being amplified by the sonic horn 101, can reach 153dB. When the sound wave propagates to a distance of 12 meters, the sound pressure level remains above 135dB. Specifically, a traditional low-frequency, normal-pressure sonic blower can reach 147dB. The relationship between decibels and energy is shown in the following formula: Where P is acoustic energy and P0 is reference energy, it can be calculated that the acoustic energy corresponding to 153dB is about 4 times that of 147dB. The cleaning capacity of the novel high-frequency high-pressure acoustic sootblower of this invention is equivalent to the simultaneous operation of four traditional low-frequency normal-pressure acoustic sootblowers, which significantly improves the cleaning efficiency.

[0023] The above are merely embodiments of the present invention. Commonly known structures and characteristics of the solutions are not described in detail here. Those skilled in the art are aware of all common technical knowledge in the field prior to the application date or priority date, are aware of all existing technologies in that field, and have the ability to apply conventional experimental methods prior to that date. Those skilled in the art can, based on the guidance provided in this application, improve and implement this solution in combination with their own capabilities. Some typical known structures or methods should not be obstacles for those skilled in the art to implement this application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of the present invention. These should also be considered within the scope of protection of the present invention, and will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
