Main products: Two models of acoustic soot blowers
Diaphragm type acoustic soot blower
Rotary flute type acoustic soot blower
The company focuses on the research and development and production of acoustic soot blowers. Its main products includeDiaphragm type acoustic soot blowerandRotary flute type acoustic soot blowerThese two products perform exceptionally well in the field of industrial ash cleaning and can effectively meet the needs of different customers.
2. Technology Origin and Professional Team
The technology of acoustic soot blowers originated from the discovery of Swedish scientists in the 1980s that the sound of ship horns could make the dust from chimneys fall off. After being successfully developed in Sweden in 1988, it was introduced to China. In 2002, Weite Technology successfully developed the rotary flute type and diaphragm type acoustic soot blowers through a large number of experiments.
Sonic dust Cleaning laboratory
The company has a strong R&D team. The core member, Professor Xu Xianjin, was formerly the academic leader of the Acoustics Research Laboratory of the Labor Protection Research Institute of Guodian Corporation. He has been engaged in the research of acoustic products for more than 30 years and has won many scientific research awards. He has profound professional attainments in the field of acoustic soot blowers. He has successively won the third prize for acoustic research and governance of the National Defense Science and Technology Commission, the second prize for power plant noise control research of the Ministry of Electric Power, the second prize for acoustic vibration research, and the second prize for research and application of acoustic soot blowers. He was invited to participate in the project appraisal of "Investigation on the Application of Acoustic Soot Blowers in Power Station Boilers" initiated by the Ministry of Electric Power in 1998.
3. Extensive application industries and scenarios
Acoustic soot blowers are widely used in multiple industries such as thermal power generation, petrochemicals, metallurgy, cement, and papermaking. In the boiler system, it can be used in key links such as cleaning the SCR denitration catalyst, superheater, economizer, air preheater, plate heat exchanger, and removing blockages in the silo, effectively improving the operational efficiency of the equipment and reducing maintenance costs.
4. Detailed Explanation of Diaphragm Soot Blower
The working principle of the diaphragm type acoustic soot blower
The working principle of the diaphragm type acoustic soot blowerIt utilizes compressed air to excite the diaphragm to vibrate, modulating the high-pressure airflow into pressure pulses. After resonance by the horn, sound waves are formed and radiated out. High-energy sound waves cause the dust to resonate and be in a free state, preventing it from adhering and accumulating on the surfaces of the boiler's heating surface and SCR reactors, etc. Under the vibration of the sound waves and the effect of gravity, the dust falls off and is discharged. The specific process is as follows:
The diaphragm is under pressure.
Compressed air at a certain pressure enters the primary chamber, causing the diaphragm to bend, and then the air enters the secondary chamber.
The diaphragm contracts, and the air beam entering the secondary chamber rapidly leaves the generator head. It vibrates repeatedly and is then amplified through the sound amplification tube to form a low-frequency high-energy sound wave.
The product composition of the diaphragm type acoustic soot blower
The diaphragm type acoustic soot blower mainly consists ofIt is composed of a generating device, a transmission device, a pipeline accessory section and a control system. All parts work in coordination to ensure the stable operation of the soot blower and achieve the efficient soot cleaning function.
Installation and technical parameters of Diaphragm type Acoustic Soot blower
When installing, configure the installation sleeve. Just make holes and weld as required. Subsequently, use bolts for connection, which is convenient for disassembly, maintenance and replacement of parts. Its technical parameters are as follows:
Model: WSB-M type
The frequency range of sound waves: 75-125Hz
Sound pressure level 1 meter away from the sound source: 143 dB
Range of application: 10 meters vertically and 6 meters horizontally
Power medium: Compressed air
Air consumption for each soot blowing: 0.42Nm³
Air source pressure: 0.5-1MPa
Power supply voltage: AC220V
Control mode: Centralized control plus local manual control
Designed annual operating hours: 8,000 hours
Weight: 80kg
Detailed Explanation of the Rotary Flute Soot Blower
The working principle of the rotary flute soot blower
The rotary flute soot blower uses a high-speed motor to drive a valve-type rotor that rotates and emits sound, continuously cutting the flow of compressed air through on-off operations. This process converts the compressed air into high-power dense and sparse waves, which are then sent into the furnace or the ash cleaning space. Under the repeated pulling and pressing of the dense and sparse waves, the accumulated ash becomes fatigued and loose, falling off and being carried away by the flue gas or discharged from the ash hopper.
Product composition of the rotary flute soot blower
The rotary flute type acoustic soot blower is also mainly composed of a generating device, a transmission device, a pipeline accessory part and a control system. All parts work together to ensure the stable operation of the soot blower and achieve the efficient soot cleaning function. Its components include solenoid valve (DN65), sound wave generator, electrical control box, gas supply pipe (DN65), cable (2.5mm), horn, etc.
Installation and technical Parameters of the rotary Flute Soot blower
The installation method is similar to that of the diaphragm type. It is equipped with an installation sleeve, and after opening a hole and welding, it is connected by bolts. The technical parameters are:
Model: WSB-X type
Sound wave frequency: 200Hz
Sound pressure level 1 meter away from the sound source: 150 dB
Range of application: 10 meters vertically and 6 meters horizontally
Power medium: Compressed air
Air consumption for each soot blowing: 3Nm³
Air source pressure: 0.5-1MPa
Power supply voltage: AC380V (three-phase four-wire system)
Control mode: Centralized control plus local manual control
Designed annual operating hours: 8,000 hours
Weight: 120kg
Operating cost
The power of the rotary flute acoustic soot blower is compressed air, and its energy consumption is extremely low. Each time the soot is blown, the air consumption is approximately 2 to 3NM³. Assuming that the ash is blown once every hour, the air consumption in 24 hours a day is 72NM³ (standard atmosphere). Based on the output of the old-fashioned piston-type air compressor with a displacement of 10m³/min, it can be converted into an electricity consumption of approximately 9 kilowatt-hours. The power of the soot blower is 1KW, and it actually consumes about 0.1 kilowatt-hour of electricity per day. So, a soot blower consumes about 10 kilowatt-hours of electricity a day.
5. Product advantages: Similarities and differences between the two soot blowers
The same advantages
Both of the two acoustic soot blowers have the following significant advantages:
The sound power is high and the dust-blowing effect is remarkable.
The ash blowing has no dead corners, ensuring that all parts of the equipment can be effectively cleaned of ash.
It operates automatically and intermittently with adjustable modes, and the operation parameters can be flexibly set according to actual needs.
The overall service life of the product is long, with the main part lasting for over 30 years, reducing the cost of replacement.
It features a high degree of automation, including manual and automatic control, operation feedback and fault feedback functions, which is convenient for operation and maintenance.
Difference
Diaphragm type soot blowers are generally recommended to be installed in SCR denitration areas and regions with low dust contentIts compressed air consumption is low, and the diaphragm is made of titanium alloy, which is strong and wear-resistant.
The rotary flute soot blower is generally installed in the tail flue of the boiler, the superheater, the economizer, the air preheater and other positionsIt has no special requirements for the soot blowing medium and requires no maintenance.
