Technical Field

[0002] Dust particles are generated during the production process in many industrial fields such as electricity, metallurgy, and chemical industry, which brings many problems in terms of environment, resources, and equipment. In terms of environment, dust emissions pollute the air, endanger health, and affect the ecology; in terms of resources, dust containing recyclable materials is not effectively treated and causes waste; on equipment, dust deposition affects heat dissipation, accelerates aging, and increases maintenance costs. Current dust treatment methods have limitations. Chemical agent sedimentation methods will cause secondary pollution and are costly, and physical filtration methods have limited efficiency in removing tiny particles. Acoustic agglomeration technology has attracted attention because it can agglomerate tiny particles for subsequent processing, but the existing acoustic agglomeration sound source system still has some shortcomings, such as inaccurate frequency adjustment, difficulty in achieving the optimal agglomeration frequency, poor adaptability, and insufficient intelligent control. Summary of the invention

[0003] The purpose of the present invention is to overcome the above problems or at least partially solve the above problems, and to propose an intelligent high-intensity sound wave agglomeration sound source system. Sound wave agglomeration is a process of using high-intensity sound waves to cause small particles to collide with each other, aggregate and grow. When sound waves propagate in a group of dust particles, they will cause the air flow around the particles to move, causing relative movement between different particles and increasing the probability of their collision with each other. The system is based on precise acoustic principles, and effectively controls the dust particle agglomeration process by generating high-intensity sound waves and accurately controlling the frequency, amplitude and phase of the sound waves. The sound source in the system can generate sound wave signals of a specific frequency band, and these signals will form an acoustic pressure field in the propagation medium. According to the physical and chemical properties of different dust particles, after adjusting the sound wave parameters, the dust particles will agglomerate under the action of this pressure field.

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] See also Figure 1-4 The present invention provides a technical solution: an intelligent high-intensity sound wave agglomeration sound source system, comprising:

[0045] The intelligent control unit is used to calculate the sound wave frequency and amplitude required for agglomeration according to the particle size and give the signal to the sound unit. The particle size value is divided into single-frequency sound source adjustment and narrow-bandwidth sound source adjustment. The particle size value is calculated according to the total average value of the detection data, and single-frequency sound source adjustment is adopted; the particle size value is calculated according to the detection data range value, and the particle size range accounts for a relatively large part, and narrow-band sound source adjustment is adopted;

[0046] The signal sound generating unit includes a single chip microcomputer for generating corresponding sound wave signals;

[0047] The power amplification and matching unit includes a power amplifier for amplifying the sound wave signal of the signal sound generating unit. The power amplifier utilizes a switch-type power amplifier chip, so that the unit can amplify the power of the initial sound wave signal emitted by the signal sound generating unit by several times while maintaining low power loss;

[0048] The sound source sound generating unit is used to generate the required high-intensity sound waves for aggregation. After the power amplifier amplifies the sound wave signal, the sound wave signal is divided into at least three paths and connected to the sound source sound generating unit. The sound source sound generating unit includes at least one wide-band sound wave generator capable of frequency modulation and at least two fixed-frequency sound wave generators located on both sides of the wide-band sound wave generator. The fixed-frequency sound wave generator and the wide-band sound wave generator work in combination to receive the sound wave signal of the corresponding line and then output the sound wave, and aggregate and superimpose the generated sound waves to enhance the sound wave intensity.

[0049] In specific implementation, the intelligent control unit includes 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 to monitor environmental parameters in real time, such as particle size value, temperature, etc., and transmit the data to the agglomeration signal optimization calculation module. The agglomeration signal optimization calculation module fuses and analyzes the data according to the preset algorithm, and combines the predefined dust particle agglomeration optimal parameter model to accurately determine the sound wave frequency, amplitude and other parameters of the adjustment signal sound unit. Its parameters include sound wave frequency and amplitude. The agglomeration signal control output module sends out command signals according to the command control 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 agglomeration efficiency roughly show a parabolic relationship, that is, there is an optimal sound wave frequency that makes the agglomeration efficiency reach the maximum value. When it deviates 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. The optimal frequency determined by the agglomeration signal optimization calculation module based on the environmental parameters is calculated as follows:

[0052]

[0053] Among them, f op is the optimal frequency, in Hz; ρ p is the particle density, in kg / m 3 ; υ is the shear viscosity of the gas, in N·s / m 2 ; d is the average particle size, in m.

[0054] In a specific implementation, the sound source sound unit also includes a multi-frequency coupled acoustic horn, which includes an f0 interface located in the middle and f1 and f2 interfaces located on both sides thereof, the outlet interface of the broadband sound wave generator is connected to the f0 interface by bolts, and the outlet interface of the fixed-frequency sound wave generator is connected to the f1 interface and the f2 interface by bolts respectively;

[0055] In this way, the total number of sound wave generators, no less than three, guarantees a sound pressure level greater than 155dB. When the sound wave generators work simultaneously, the sound waves they generate will be superimposed at the outlet of the multi-frequency coupled acoustic horn. If the frequency, phase and amplitude of these sound wave generators are precisely controlled, their sound waves will reinforce each other, thereby producing a greater sound output. Under the action of the multi-frequency coupled acoustic horn, the sound shell can be enhanced.

[0056] In a specific implementation, the multi-frequency coupled acoustic horn includes a horn section A, a middle special-shaped horn and special-shaped horns on both sides. The horn section A is a pipe mouth that changes from square to round, which is flange-connected to the corresponding wide-band sound wave generator and fixed-frequency sound wave generator respectively. The interfaces between the horn section A and the wide-band sound wave generator and the fixed-frequency sound wave generator are the corresponding f0, f1 and f2 interfaces. One ends of the middle special-shaped horn and the special-shaped horns on both sides are connected to each other, and the other ends are flange-connected to the horn section A.

[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 modulation and a fixed frequency whistle sound generator;

[0058] With this setting, the electromagnetic modulated sound wave generator can achieve the ability to adjust from low frequency to high frequency, and the whistle sound generators with fixed frequencies on both sides can ensure the stable output of high-frequency sound waves. When the equipment is running, it is only necessary to start the fixed-frequency sound wave generator at the beginning; when the particle size of a single particle changes, the electromagnetic modulated sound wave generator is turned on, and the sound wave agglomeration sound source is 5000Hz, which can achieve a wide range of frequency adjustment capabilities from 100Hz to 10KHz, and in the entire frequency adjustment range, it can maintain a stable sound pressure level of 160dB output.

[0059] In a specific implementation, a phase adjuster is further provided between the power amplification and matching unit and the sound source sound generating unit, the power amplifier of the power amplification and matching unit and the wide-band sound wave generator are directly connected via a line, and the phase adjuster is provided between the power amplifier and the fixed-frequency sound wave generator, and they are connected in sequence via lines;

[0060] With such arrangement, under the action of the phase adjuster, the phase of the signal of each fixed-frequency sound wave generator is adjusted so that the sound emitted by each fixed-frequency sound wave generator reaches the aggregation position at the same time, thereby optimizing the effect of sound wave aggregation.

[0061] In specific implementation, the system also includes a real-time feedback loop, which is used to feed back the actual effect of sound wave agglomeration in the agglomeration space to the intelligent control unit so as to make further corrections to the next regulation and ensure that the agglomeration effect continues to be in the best state.
