[0043] The technical solutions in the embodiments of the present application will be described in detail below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.
[0044] Please refer to Figures 1-4 , the present application provides a technical solution: an intelligent high-strength sound wave agglomeration sound source system, comprising:
[0045] The intelligent control unit is used for signaling the sound emitting unit according to the particle size of particulate matter and the frequency and amplitude of the sound wave required for agglomeration. The particle size of particulate matter is adjusted in a single frequency sound source adjustment mode and a narrow frequency bandwidth sound source adjustment mode. The particle size value is calculated according to the average value of the total number of detection data. The single frequency sound source adjustment mode is adopted. The particle size value is calculated according to the detection data range value. The particle size range is the part with a heavy proportion. The narrow frequency bandwidth sound source adjustment mode is adopted.
[0046] The signal emitting unit comprises a single-chip microcomputer for generating a corresponding sound wave signal.
[0047] The power amplification and matching unit comprises a power amplifier for power amplifying the sound wave signal of the signal emitting unit. The power amplifier uses a switching power amplifier chip, so that the unit can amplify the initial sound wave signal emitted by the signal emitting unit by several times while maintaining a low power loss.
[0048] The sound source emitting unit is used for generating a high-intensity sound wave required for agglomeration. After the power amplifier power amplifies the sound wave signal, the sound wave signal is at least divided into three paths and connected to the sound source emitting unit. The sound source emitting unit comprises at least one wideband sound emitter capable of frequency modulation and at least two fixed-frequency sound emitters located on both sides of the wideband sound emitter. The fixed-frequency sound emitter and the wideband sound emitter work in combination to receive the sound wave signal from the corresponding line and output the sound wave. The generated sound wave is agglomerated and superimposed to enhance the sound wave intensity.
[0049] In specific implementation, the intelligent control unit comprises an environment and particle size collection and analysis module, an agglomeration signal optimization calculation module, and an agglomeration signal control output module.
[0050] The environment and particle size collection and analysis module is used for real-time monitoring of environmental parameters such as the particle size value of particulate matter and temperature, and transmitting the data to the agglomeration signal optimization calculation module. The agglomeration signal optimization calculation module fuses and analyzes the data according to a preset algorithm, and accurately determines and adjusts the sound wave frequency, amplitude, and other parameters of the signal emitting unit in combination with a predefined optimal parameter model of dust particle agglomeration. The parameters include sound wave frequency and amplitude. The agglomeration signal control output module controls the issuance of instruction signals according to the instructions of the agglomeration signal optimization calculation module.
[0051] In specific implementation, the sound wave frequency affects the overall dust removal effect by changing the agglomeration efficiency. The frequency and the agglomeration efficiency roughly present a parabolic relationship, that is, there is an optimal sound wave frequency that makes the agglomeration efficiency reach a maximum value. When deviating from this optimal sound wave frequency, the agglomeration efficiency will be greatly reduced. The optimal sound wave frequency is strongly correlated with the average particle size of particulate matter. The optimal frequency determined by the agglomeration signal optimization calculation module according to the environmental parameters is calculated as follows:
[0052]
[0053] wherein f op is the optimal frequency, unit: Hz; p p is the particle density, unit: kg / m 3 ; υ is the shear viscosity coefficient of the gas, unit: N·s / m 2 ; d is the average particle size of the particles, unit: m.
[0054] In specific implementation, the sound source sounding unit further comprises a multi-frequency coupling acoustic barrel, which comprises an f0 interface in the middle and f1 and f2 interfaces on both sides. The outlet interface of the broadband sound wave generator is connected to the f0 interface by bolts, and the outlet interfaces of the fixed-frequency sound wave generators are connected to the f1 and f2 interfaces by bolts, respectively.
[0055] In this way, the total number of sound wave generators is not less than three, which ensures a sound pressure level of more than 155 dB. When the sound wave generators work simultaneously, the sound waves generated by them will be superimposed at the outlet of the multi-frequency coupling acoustic barrel. If the frequency, phase and amplitude of these sound wave generators are accurately controlled, their sound waves will be enhanced, thereby generating greater sound output. Under the action of the multi-frequency coupling acoustic barrel, the sound beam can be enhanced.
[0056] In specific implementation, the multi-frequency coupling acoustic barrel comprises a barrel A section, a middle profiled horn and two profiled horns on both sides. The barrel A section is a square-to-round pipe opening, which is connected to the corresponding broadband sound wave generator and fixed-frequency sound wave generator flanges. The interfaces between the barrel A section and the broadband sound wave generator and fixed-frequency sound wave generator are the corresponding f0, f1 and f2 interfaces. One end of the middle profiled horn and the two profiled horns on both sides converges, and the other end is connected to the barrel A section flange.
[0057] In specific implementation, the broadband sound wave generator and the fixed-frequency sound wave generator respectively adopt an electromagnetic modulation sound wave generator capable of frequency adjustment and a whistle sound generator with fixed frequency.
[0058] In this way, the electromagnetic modulation sound wave generator can realize the adjustment ability from low frequency to high frequency, and the two fixed-frequency whistle sound generators on both sides can ensure stable high-frequency sound wave output. During device operation, only the fixed-frequency sound wave generator needs to be started initially. When the particle size of single particles changes, the electromagnetic modulation sound wave generator is turned on, and the sound wave agglomeration sound source is 5000 Hz. It can realize the frequency adjustment ability in a wide range of 100 Hz to 10 KHz, and can maintain a stable sound pressure level of 160 dB output in the entire frequency adjustment range.
[0059] In specific implementation, a phase adjuster is further arranged between the power amplification and matching unit and the sound source sounding unit, the power amplifier of the power amplification and matching unit is directly connected with the wide-band sound wave sounder through a line, and the phase adjuster is arranged between the power amplifier and the fixed-frequency sound wave sounder and connected with them through a line in sequence.
[0060] In this way, under the action of the phase adjuster, the phase of the signal of each fixed-frequency sound wave sounder is adjusted, so that the sound emitted by each fixed-frequency sound wave sounder reaches the gathering position at the same time, and the effect of sound wave gathering is optimized.
[0061] In specific implementation, the system further comprises a real-time feedback loop, which is used to feed back the actual effect of sound wave gathering in the gathering space to the intelligent control unit, so as to make further correction for the next regulation and control, and ensure that the gathering effect is continuously in the best state.
[0062] A regulation and control method of an intelligent high-intensity sound wave gathering sound source system, which is applied to the intelligent high-intensity sound wave gathering sound source system in any one of the above aspects, and comprises a single-frequency sound source adjustment method and a narrow-band sound source adjustment method.

[0066] S3, detecting data two by using the particle size detection sensor again to obtain a particle size initial value u1;
[0067] S4, transmitting the data two signal to the signal processor, in order to produce an optimal gathering effect, the signal processor analyzes the data according to a predetermined algorithm, so that the wide-band sound wave sounder capable of adjusting frequency emits a sound source with an initial frequency f0, and the fixed-frequency sound wave sounders on the symmetric two sides emit sounds with frequencies f 10 and f 20 , to produce the second sound wave gathering in the dust environment.
[0068] S5, the intelligent control unit performs a cycle operation of steps S1 to S4 until a qualified particle size value u m is detected, and the operation is stopped.

[0071] S12. Data signal is transmitted to the signal processor.

[0072] S13. Use the particle size detection sensor to detect data 2 again to obtain the initial particle size values u1 to u2;
[0073] S14. Data signal two is transmitted to the signal processor. To produce the optimal aggregation effect, the signal processor analyzes the data according to a predetermined algorithm, causing the frequency-tunable broadband sound wave generator to emit a sound source with an initial frequency of f0, while simultaneously causing the fixed-frequency sound wave generators on both sides to emit sound at f0 respectively. 12 and f 22 The frequency of sound emission generates a second sound wave aggregation in the dusty environment;
[0074] S15. The intelligent control unit operates in a loop from steps S11 to S14 until a qualified particle size value u is detected. m-1 ~u m Stop operation.
[0075] In practical implementation, in the single-frequency sound source adjustment method, the acceptable particle size value u m The determination is based on the maximum allowable particle size value set for the target application scenario after dust treatment. In the narrow-band sound source adjustment method, the qualified particle size value u m-1 ~u m The determination is based on the particle size range set for the target application scenario after dust treatment.
