Characteristic Research On Inversion Problem Of Quantum Acoustic Field And Its Manipulation On Suspended Particles

The rapid development of social and national economy has led to a huge consumption of energy resources.The consumption of coal,oil and biomass as major energy resources usually produces large quantities of fine particulate matter(PM_2.5),which threatens human health and atmospheric environment.As it is difficult for traditional dust removal methods to completely remove fine particles from the exhaust gas,the acoustic control of PM_2.5.5 pollutants has gradually become a hot research area of advanced dust removal technology.In order to develop the acoustic control technology of PM_2.5.5 pollutant,the characteristic research on inversion problem of quantum acoustic field and its manipulation on suspended particles is proposed depended on theory.Based on the structural coherence and destructive coherent characteristics caused by acoustic wave superposition,the theoretical model of quantum acoustic field inversion?QAFI?for quantum acoustic source and waveguide is established.The main mechanism of suspended particles manipulated by QAFI is established,and the engineering design criteria and manufacturing method of application device are formulated.The acoustic manipulation platform device of suspended particles is developed,including the quantum acoustic source pair coupled one-dimensional waveguide and the orthogonal quantum acoustic source pairs coupled two-dimensional waveguide.Then,from the point of view of experiment and simulation,by studying the acoustic characteristics of quantum acoustic source,the inversion amplification and its controllability are verified.By studying the acoustic characteristics of acoustic wave evolution in waveguide,the mechanism of quantum acoustic field inversion superposition is verified.These results demonstrate the feasibility of the theoretical model of QAFI and the effectiveness of the particle manipulation platform device based on the theoretical model.Through the experiment of tobacco-fired smoke particles,the suspended particles manipulation through modulated multiple acoustic wave packets with a pair of opposite quantum acoustic sources is studied,and the properties of suspended particles manipulated by QAFI are obtained.Combined with the acoustic field distribution pattern in the waveguide,the relation between the manipulation effect of suspended particles and the multiple acoustic wave packets is analyzed,and the effective correspondence of both is obtained.The remarkable manipulation efficiency is verified.Then,using the two-dimensional waveguide experimental device,the suspended particles manipulation with the pairs of orthogonal quantum acoustics sources of phase adjustable is studied,and the manipulation effect of suspended particles is obtained.Through the phase control of two sets of orthogonal opposite acoustic sources,the non-uniform two-dimensional acoustic standing wave field generated in the waveguide is verified,and the spatial and temporal distribution difference between the?phase and 0 phase acoustic field is obtained.By analyzing the relationship of particle manipulation effect and acoustic field distribution pattern,the effective correspondence is obtained,and the remarkable universality is verified.Finally,through the acoustic manipulation experiment of suspended particles under six different thermal environment conditions,the study on the acoustic aggregation of suspended particles manipulated by temperature tuning is carried out,and the manipulation effect is obtained.Through the time domain,frequency domain and probability analysis of opacity data,the temperature effect of the particle acoustic aggregation process is obtained.By studying the resonance characteristics of waveguide,the parameter change of the resonant frequency and the maximum acoustic pressure with temperature is obtained.By analyzing the relationship between the manipulation effect of suspended particles and the sub-resonance,resonance and super-resonance,the effective correspondence between temperature tuning and particle acoustic aggregation is obtained,and the outstanding potential of eliminating error is verified.
