Description

The invention relates to the technology of ultrajet processing, diagnostics of materials and to the preparation of activated suspensions and can be used in various industries (mining, chemical, metallurgical, etc.).

In the existing known methods, the process of preparing structurally heterogeneous hydro-media, consisting of a mechanical mixture of the liquid phase (liquid, matrix) and particles of the solid phase (filler, powder) is divided in time. As a rule, fractionation and/or dispersion of the original solid product is carried out mechanically, and then it is mixed with a liquid matrix (liquid carrier). In this case, the mixing process can be combined with the grinding of the filler, separation, etc. (See, for example, RU 2119824, B01F 3/12, 1998).

Such a sequence of actions reduces the efficiency of activation of the liquid-phase matrix by solid filler particles. Among the processes activating the liquid matrix are diffusion, chemical and other physical processes and phenomena occurring at the interface between two phases (see the above patent). The presence of passivating chemical and molecular (adsorption) films on the surface of the powder particles also reduces the efficiency of the process of activation of the liquid-phase matrix (LM) by the elements of the dispersed solid phase (SP).

To eliminate these shortcomings, the process of dispersion of the solid phase is combined with the process of forming a suspension (see, for example, RF patent 2097180, class B28C 5/36, 1997). Due to this, it is possible to increase the efficiency of the activation process of a structurally inhomogeneous hydro-environment (final product), i.e. get its new quality and improve consumer properties.

However, this method also has the following disadvantages:

- the difficulty of regulating the preparation of a suspension with desired properties due to the uncontrolled dispersion process;

- no activation of the liquid matrix during the preparation of the suspension;

- restrictions on the strength characteristics of TF;

- the complexity of obtaining multicomponent suspensions;

- low productivity of the process of saturation of the liquid matrix with TF particles.

The closest technical solution adopted as a prototype is a method for preparing suspensions (US Pat. RF 2397012, IPC B01F 3/12, publ. 20.08.2010), which consists in combining the process of dispersion of the solid phase with the process of formation of a structurally heterogeneous hydro-environment, which is carried out by exposing the target to a jet of liquid for a certain time, which at the moment of interaction with the target has a given specific kinetic energy and exposure time sufficient to destroy the target material; spots of contact with it. And also by the fact that the change in time of the location on the target surface of the spot of contact with it of a jet of a structurally inhomogeneous hydro-environment is carried out by moving the jet of a structurally inhomogeneous hydro-environment and the target relative to each other; the effective time of the impact of the jet on the target is defined as the ratio of the diameter of the contact spot of the jet with the target to the velocity of the relative movement of the jet over the target surface, which ensures the maximum intensity of target destruction; a jet of a structurally inhomogeneous hydro-environment has constant or changing energy parameters; a structurally inhomogeneous hydro-environment is supplied to the target in the form of a continuous or intermittent jet of a given duty cycle; change the angle of attack of the jet; changing the location on the target surface of the spot of contact with it jets of structurally inhomogeneous fluid is carried out continuously or periodically; as a structurally inhomogeneous hydro-environment for the jet, a structurally inhomogeneous hydro-environment formed after the impact of the jet on the target is used; which is used as the remaining pure structurally heterogeneous fluid or with solid particles; as a structurally inhomogeneous hydro-environment, a medium is used, the particles in which consist of a solid material, the hardness of which is less than, greater than or equal to the hardness of the target material; quartz, flint or diamond is used as a solid material; as a target, a target is used, consisting of at least two halves made of materials of different hardness; the half of the target on the side of the impact of the jet has a greater hardness; the impact of a jet of a structurally inhomogeneous hydro-environment is carried out at the junction of the halves of the target; a jet of a structurally inhomogeneous hydro-environment acts on a target immersed in a liquid; the liquid in which the target is immersed contains hard-to-wear abrasive or particles from the target material or an identical material; as the specified abrasive is ground, it is added to the specified structurally heterogeneous hydraulic medium; as an activated structurally heterogeneous hydro-environment with desired properties is obtained, it is selected from different levels; as a structurally heterogeneous hydro-environment, a polycomponent emulsion, solution or suspension is used; a saline solution is used as a polycomponent structurally heterogeneous hydro-environment. The selection of a structurally inhomogeneous hydro-environment and the formation of a jet is carried out with equipment made of the same material as the target. The jet of a structurally inhomogeneous hydro-environment and the hydro-environment itself, in which the target is located, are affected by physical fields; the impact is carried out by a thermal field; during the impact of a jet of a structurally inhomogeneous hydraulic medium on the target, the parameters of acoustic emission (AE) are measured and they are used to judge the intensity of the process of blurring the target and obtaining an activated structurally inhomogeneous hydraulic medium with a decrease in the AE parameters by no more than 5-7%, relative movement of the jet is carried out structurally inhomogeneous hydro-environment and target, which is stopped when the AE parameters reach the previous values.

The disadvantage of the known method is the lack of methods to achieve a stable homogeneous structure for processing inhomogeneous hydraulic media (liquids) of the initial structurally inhomogeneous hydraulic systems: a structurally inhomogeneous hydroenvironment, for example, based on carbon nanotubes, graphene, water-soluble polymers, etc.

The objective of the invention is to determine the number of minimum required cycles (time) of processing, providing a stable homogeneous structure of the original structurally heterogeneous hydraulic systems: structurally heterogeneous hydromedia, for example, based on carbon nanotubes, graphene, water-soluble polymers, etc.

The technical result consists in reducing energy costs and the duration of processing of the initial structurally heterogeneous hydraulic media with the provision of a stable homogeneous structure of the hydraulic media.

The specified task and technical result are achieved by the method of processing structurally inhomogeneous hydraulic media, which consists in combining the process of dispersion of the solid phase with the process of formation of a structurally inhomogeneous hydraulic medium by exposing the solid phase to a jet of a structurally inhomogeneous hydraulic medium formed in a nozzle jet-forming unit and having at the moment of interaction with the solid phase, the specific kinetic energy and exposure time sufficient to destroy the material of the solid phase, the impact on the solid phase is carried out by a supersonic jet of liquid, while the solid phase is used in the form of a target, which is a compact solid material, and when the target is exposed to a supersonic jet of a structurally inhomogeneous hydraulic medium liquids change the location of the supersonic jet contact spot on the target surface in time to maintain the efficiency of target destruction. According to the invention, the process of processing a structurally inhomogeneous hydro-environment is repeated until the required stabilization of acoustic emission signals (high-frequency elastic deformation waves) generated in the zone of impact of the jet on the target and fixed by piezoelectric transducers.

And also by the fact that the piezoelectric transducers are installed on the nozzle jet block and on the target against which the structurally inhomogeneous hydraulic medium hits, and the diagnostic comparison of acoustic emission signals is carried out by analyzing these signals recorded by the piezoelectric transducers.

And also by the fact that emulsions and/or microsuspensions based on carbon nanotubes, graphene and water-soluble polymers are treated as initial structurally inhomogeneous hydromedia.

And also by the fact that the processing of the initial structures is carried out on a technological installation containing a device for periodic or continuous supply of structurally inhomogeneous hydro-media for processing, an ultra-jet formation unit with a jet-forming nozzle, a housing with a target, piezoelectric transducers (sensors) of acoustic emission (AE) waves - waves of elastic deformation of the medium generated during the formation of a high-velocity ultrajet (US) on the contact surfaces of the nozzle and in the US itself.

And also by the fact that re-processing is carried out on one technological installation in a cyclically closed mode.

And also by the fact that several installations are used for processing, on which the structurally heterogeneous hydro-environment formed at the previous installation is sequentially processed (homogenized).

And also by the fact that a copper plate is used as a target.

And also by the fact that the treatment area is connected to a generator of ultrasonic vibrations.

Thus, due to the fact that the process of processing a structurally inhomogeneous hydro-medium is repeated until the required stabilization of the acoustic emission signals (high-frequency elastic deformation waves) generated in the zone of impact of the jet on the target and fixed by piezoelectric transducers, it is possible to determine the number of minimum required cycles (time) of processing, which ensures a stable homogeneous structure of the initial structurally inhomogeneous hydromedia: emulsions and/or microsuspensions, for example, based on carbon nanotubes, graphene, water-soluble polymers, etc.

In technical terms, a multivariant implementation of the method is possible, its combination with other additional (external) physical and technological influences, factors, fields, etc. There is a technical possibility of obtaining structurally heterogeneous hydro-media with different sizes of FF, their separation in a natural way (sedimentation) or in special separators. The use of carbon nanomaterials makes it possible to obtain the most preferable type of structurally inhomogeneous hydraulic media - with a minimum spread in the size of the dispersed material

Thus, the patented method has a great innovative potential, exceeding the potential of the classical method of jet-impact activation of liquids.

in fig. 4 is a diagram of LPG homogenization in a closed cycle at a hydrotechnological plant.

in fig. 5 - Scheme of LPG homogenization using several hydroprocessing units

The initial structurally inhomogeneous hydro-environment (SNG), for example, a suspension to be homogenized, (Fig. 1 pos. 1) in which there are different-sized accumulations of cluster-like microstructures (Fig. 1 pos. 4, 5, 6), for example, in the form of molecular linkages of carbon nanotubes among themselves, such as hydrosolid-phase small-sized nodules (lumps), is compressed to pressures

P=50-500 MPa,

depending on the strength of adhesion of individual structural elements (particles) of the dispersed hydro-environment. Then, with the help of a standard jet-forming path used in technological equipment for hydrocutting materials, a high-speed jet is formed from the initial LPG (Fig. 1, item 12) in the jet-forming nozzle 2 (Fig. 1), which moves at a speed

VC

towards the solid target 9, made of an erosion-resistant material, such as structural nitride ceramics or hard alloy type VK-8.

During the shock-dynamic interaction of an ultrajet (US) with the surface of a solid target, i.e. when exposed to 12 on 9, as shown in Fig. 1, there is a very intense conversion of the kinetic energy of the US into the surface energy of the spray cloud formed by shock spraying of the initial SNS to an ultrafine state and the formation of an aerosol cloud. Moreover, as calculations show, the sizes of submicrodroplets of this cloud are smaller than the sizes of structural inhomogeneities of the initial hydro-medium. This, from a physical point of view, is the dominant mechanism of homogenization of the CIS, primarily cluster-like nodules of microsuspensions and dispersed emulsions.

The problem is to determine the time (duration, cyclicity) of the process of ultrajet homogenization (USH) of liquid-phase structures, which in this case are size-variable microsuspensions. Moreover, the economic cost of excessive repeated repetition of the cycle is quite obvious: compression and acceleration of the SNS in the form of US - shock braking of US - the formation of an ultrafine spray - condensation and obtaining a homogenized hydrosubstance in the form of a more homogeneous suspension. Therefore, the purpose of the proposed method is to determine the required number of repetitions of the SSG cycle of the original LPG according to the criterion of uniformity of the formed hydrosubstance, for example, a suspension based on carbon nanotubes.

The main informative feature of the parameters of inhomogeneities in the initial LPG, which strikes the surface of a solid target in the form of a US, is the spread of amplitude values and the repetition rate of high-frequency (up to 10 MHz) impulse-like waves of elastic deformations of the target material (Fig. 1, item 7) - acoustic emission waves (AE ). In addition to the propagation of AE waves over the target material, they move along the hydrocolumn of the US itself, as shown in Fig. 1 pos. 13.

On the target 9, the AE waves are recorded by the piezoelectric transducer 10 (AE signal sensor) and processed by the appropriate acoustic emission instrumentation. AE waves from the side of the generated US from the initial LPG and coming along the column from the zone of its impact to the target (Fig. 1 pos. 11) are recorded by sensor 3. Moreover, these AE sensors - 3 and 10 must have good acoustic contact with the object in which they propagate and/or AE waves are generated, for example, by applying an immersion composition such as CIATIM grease to the contact site. The coefficient of variation v can be chosen as an informative sign of the AE signal. This coefficient is determined by the ratio of the root-mean-square deviation a to the mathematical expectation m of the level of amplitude values recorded by AE sensors and formed in the measuring equipment by analog-to-digital signal processing units:

Obviously, the more stable the AE signal, the smaller the spread in the levels of AE waves, which is directly related to the inhomogeneities of the homogenized SNS due to their influence on the dynamics of the impact interaction between the US and the target.

Therefore, in the process of multiple SSG of the original SNS, a relation of the form should take place:

where:

n is the number of repetitions of the USG process;

νo is the coefficient of variation of the AE signal upon impact with the US target of a completely homogenized (homogeneous) suspension or emulsion.

It follows from relation (2) that the dependence of unstable changes in the AE signal level in the form of the coefficient of variation ν (n), as a function of the number of repetitions of the USG process, tends to some fixed value νo=const. This value of ν o is in fact the asymptote of the function ν(n) as shown in FIG. 2 Therefore, for a given value of AE signal instability A, determined by the difference between the current coefficient of variation ν(n) and its asymptotic value νo, the repetition of the USG process can be stopped. It is in this case that the required degree of homogenization of the initial LPG will take place, determined by direct studies of the homogeneity of the obtained highly dispersed homogeneous hydroproduct:

where:

nH - functionally necessary number of repetitions of the USG cycle, ensuring the validity of relation (3).

It should be noted that due to the probabilistic nature of the SSG process, it is practically impossible to ensure a value of νo close to zero, however, the specific value of νo depends on many factors of this process and is determined in the course of preliminary installation experiments with subsequent mathematical processing of the results obtained. In particular, an exponential function of the form (see Fig. 2) has a satisfactory approximation ability

where:

A - the value of v with a single USG (n=1);

k is a coefficient that actually characterizes the efficiency of the USG process as a whole.

Some remarks.

1. The reliability of the exponential representation of the function of changing the geometric inhomogeneities of the structure of the initial LPG, in the process of repeating the operation by the action of the SSG, in addition to direct experimental studies, is generally confirmed by mathematical formalization of the probabilistic nature of dispersion, which is similar to the analysis of the well-known "scale strength factor" of solids.

2. In addition to the coefficient of variation, other informative parameters of the set (array) of AE signals can be used. In particular, along with the traditional spectral representation, from the physico-energetic point of view, the amplitude analysis of AE pulses, which is unambiguously related to the structural inhomogeneity of the US-impact disturbance of the zone of dynamic contact of the LPG with the target, can be considered quite representative, as shown in Fig. 2.

Thus, by analyzing the AE signals, it is possible to obtain objective, physically substantiated information about the degree of homogenization of the initial LPG in the process of impact-dynamic US impact on it.

An example of the implementation of the method

To evaluate the effectiveness of the proposed method for express determination of the necessary repetition of US homogenization cycles by comparative analysis of AE signals, direct experimental studies were carried out. After ultrasonic homogenization of the initial LPG on a standard process unit for hydraulic cutting of materials by FLOW (USA), a comparative evaluation of the results of the following experiments was carried out:

1. Control experiments (K), during which technically pure water acted as a structurally inhomogeneous hydro-medium, which was mixed with a high-speed US by ejection according to the abrasive supply scheme. Then, the US “diluted” in this way acted on a moving target. In this case, the AE parameters were measured and the coefficient of variation was determined

2. The first model experiment (M1) consisted in supplying a portion of the suspension with a volume V1, in which quasi-cluster accumulations of carbon nanotubes were present, to the hydroabrasive jet formation unit. Then, the “diluted” structurally inhomogeneous hydro-medium interacted with the moving target with simultaneous fixation of the parameters of the AE signals and subsequent calculation of their coefficient of variation

The volume of the "diluted" homogenized suspension was:

where

- the volume of water that was spent on the formation of homogenizing US;

(kg/s) - standard water consumption of the process unit;

τ

- the time of the experiment

Then, settling and fine filtration of the US-homogenized suspension were carried out, which made it possible to obtain LPG of the initial volume

According to another option for preparing the subsequent US homogenization, fine filtration of the volume was carried out

and the resulting substrate was mixed with technically pure water, the volume of which

corresponded to the initial volume of non-homogenized suspension:

Thus, as a result of this experiment, the initial volume of a structurally inhomogeneous hydro-medium was obtained for further US-homogenization, but it had already passed one stage of shock-dynamic dispersive treatment.

3. The second and subsequent experiments (M2, M3, etc.) methodically fully corresponded to the first stage of US homogenization. According to their results, the coefficient of variation of AE signals was determined

etc., and also prepared the required volume of the suspension:

At the same time, the coefficients of variation of AE signals were compared with each other and the size-dispersion quality of homogenized suspensions was determined until it reached a stable value according to the standard method.

и

поверхности после УС-воздействия определялся коэффициент вариации микротопографии профиля по соотношению (1), где под m понималось значение

исследуемой поверхности.It should be emphasized that in addition to the above, a direct assessment of the instability of the characteristics of the LPG was carried out, which was carried out by measuring the geometric variability of the surface microrelief, which is directly related to the erosive ability of the US - homogenized suspension. At the same time, in addition to the standard values

And

surface after US exposure, the coefficient of variation of the profile microtopography was determined by relation (1), where m was understood as the value

surface under study.

These experiments were very time consuming, but they made it possible to obtain physically reliable information about the characteristics of structural inhomogeneities of homogenized suspensions by evaluating their hydroerosive effect on the surface layer of the target. Taking into account the relative functional insufficiency of this effect of the solid-dispersed fraction of nanosuspensions as a target, we used not a highly erosion-resistant material such as a VK-8 hard alloy, but a polished plate made of electrolytic copper M1. This increased the contrast of the profiles of the surfaces subjected to the action of the US, formed with different fractional composition of the characteristics of the CIS.

For methodological generality and increasing the reliability of comparative analysis, the quality of US homogenization was also evaluated by direct calculation of the coefficient of variation of the submicrogeometric parameters of the solid dispersed fraction studied by LPG.

In table. 1 shows the obtained data normalized to the values of the control experiment.

Comparative analysis of the degree of homogenization of a cluster-like suspension based on carbon nanotubes by analyzing AE signals

Based on the results of the experiments, the following conclusions were made:

а также неравномерностями микропрофиля поверхности, сформированной эрозионным действием УС из СНГ. Количественные оценки, подтверждающие справедливость данного положения не трудно получить расчетом соответствующих коэффициентов корреляции.1. Informative signs of AE signals from the US homogenization zone closely correlate with other physically objective characteristics of the CIS instability: the spread of carbon nanotube clusters

as well as irregularities in the microprofile of the surface formed by the erosive action of US from the CIS. Quantitative estimates confirming the validity of this provision are not difficult to obtain by calculating the corresponding correlation coefficients.

2. Informative signs of AE are the most sensitive to the structural-phase inhomogeneities of the US in comparison with other parameters. This is explained by the impulse nature of the generation of bursts in the wave pattern of the formation of a high-frequency acoustic field under multiple impacts of ensembles of linked nanoparticles in comparison with the relatively uniform "noise" effect of their individual structural components.

3. In this case, repeated (M2) US-homogenization provides high quality of structurally inhomogeneous hydromedia according to the criterion of geometric stability - the scatter in size and concentration of accumulations of quasi-cluster microstructures. At the same time, the values of the coefficients of variation of the informative parameters are close to the control values.

In the future, the AE method makes it possible to express-optimize and diagnose other parameters of the process of ultrasonic treatment of a structurally inhomogeneous hydro-medium, in particular, to determine the rational angle of interaction of a homogenized LPG jet with the surface of a solid target.

Thus, in terms of technical characteristics and controllability, US-homogenization significantly exceeds the known prototypes of ultrasonic stabilization of the dispersion characteristics of suspensions from initially structurally inhomogeneous hydraulic systems. Moreover, the analyzed hydrophysical technology can be effectively implemented on one US-homogenizing unit, as shown in Fig. 4. If it is necessary to increase the productivity of the process of homogenization of structurally inhomogeneous hydromedia, their US processing can be carried out on several sequentially operating units, as is schematically shown in Fig. five.

However, as shown by preliminary experiments, as a rule, the required structural-phase quality of the initially inhomogeneous micro- and nano-structurally inhomogeneous hydromedia is ensured by the criterion of the minimum scatter of the geometric characteristics of their solid-phase component even with 2-fold US homogenization.

It is obvious that the application of the AE method is highly expedient not only for the implementation of the process of processing liquids, but also for information and diagnostic support for the technology of ultrajet processing of materials and liquids.
