The device operates as follows (figure 1 and figure 2).

The first step is a preliminary ultrasonic activation (activation) of water and pre-DCU activation of the substrate (9). For ultrasonic examination of activated water by the third ultrasonic testing of generator (36), the third power amplifier (37) and the third ultrasonic inspection hydroacoustic radiator (38)located at the geometric center of the tank (6), is establishing, strengthening to the required level and omnidirectional radiation of the ultrasonic acoustic waves at a frequency ω3in the frequency range 104-106Hz. Acoustic wave impinges on the inside of the tank (6) water and alter its physico-chemical properties: increases the softness of the water (it should be neutral and transparent - content CENTURIES of not more than 0.1 mg/l), etc.

For ultrasonic inspection of activation of the substrate by using the seventh ultrasonic generator (45), the seventh power amplifier (46), sedim the th UT air radiator (47) is the formation, gain up to the required level and directed toward the substrate, the radiation of the ultrasonic acoustic waves at a frequency ω7in the frequency range 104-105Hz. An acoustic wave impinges on the surface of the substrate and partially modify its physico-chemical properties, while maintaining the structure of the material.

The next step is the preparation of the COP. For this purpose, the computer (1) is calculated required amount of dye, water and excipients depending on the nature of the substrate, which must be submitted to the tank (10) for the preparation of the COP and its activation. On command from a computer, the required amount of water from the reservoir (6) with the corresponding outlet pipe (7) enters the tank (10), the required amount of dye from the reservoir (2) for the dye on the relevant pipeline (3) enters the tank (10), as well as the required number of auxiliary substances from the reservoir (4) with the corresponding outlet pipe (5) enters the tank (10).

In the vessel (10) using the first device (13) is intense and adjustable (depending on the characteristics of water, dye, auxiliary substances, as well as the substrate to be dyed) speed (rpm) mechanical mixing of the COP, and using the first device is tion (14) is created excessive static pressure of 0.5-1.0 ATM, accelerating physical-chemical processes in the preparation of the COP and its activation.

By using the first ultrasonic inspection of the generator (32), the first power amplifier (33) and the first ultrasonic inspection sonar emitter (11)located at the geometric center of the vessel (10), is the formation, increased to the required level and omnidirectional radiation of acoustic waves at the frequency ω1in the frequency range 104-106Hz. Hydroacoustic waves affect the COP and due to physical effects such as cavitation (causes micro impact, mikropotokami, heating and other), svecokarelian effect (causes intense penetration of CA in the smallest pores of the coated substrate), dispersion, etc. to increase its quality (improved dispersion of the COP and others). This circumstance allows to accelerate the dyeing process, to increase the depth of Progresa substrate, improves rowmote and strength dyeing, and also allows you to lower the temperature, the time of dyeing, etc.

Using the first generator (48) electromagnetic signals, a first amplifier (49) electromagnetic signals and the first emitter (12) electromagnetic signals located at the geometric center of the vessel (10) is above or below the sonar emitter (11), assests which is the formation, gain and omnidirectional radiation of electromagnetic waves at a frequency ω1in the range of 104-108Hz. Electromagnetic waves also affect the COP and improve its quality (improved dispersion of the COP and others).

Prepared by the above-described way, the COP is poured into the supply tank to the spray device (16) and the COP under the influence of compressed air coming from the corresponding reservoir to the spray device and the spray gun, the spray apparatus is directed, in the scope of the current location of the moving conveyer (22) substratum, intensively sprayed, carrying out dyeing of the substrate.

Simultaneously with the fourth ultrasonic generator (39), the fourth amplifier (40) and the first ultrasonic inspection of air radiator located behind the spray device (16) and not escape from it painted substrate, formation, increased to the required level and vysokozatratnoe, collinear with the spray-jet radiation of acoustic waves at the frequency ω4in the range of 104-106Hz. Acoustic wave intensity up to 100 W/cm2and more, depending on the nature of the substrate, substantially increase (at the expense of much higher intensity compared to the intensity of the spray jet) the degree of penetration of the COP in the painted substrate during his stay in the field of spray-p and significantly improve the fixation of the COP on the surface of the coated substrate. This decreases the air pressure in the spray apparatus and decreases the consumption of CA in the dyeing process of the substrate.

Simultaneously with the fifth ultrasonic generator (41), fifth (multichannel: at least two channels of a power amplifier, and the second (18), third (19), fourth (20) and fifth (21) air ultrasonic emitters are located respectively at the top, bottom, left and right of the painted substrate, are currently in the region of the spray jet spray device (16), is the formation, increased to the required level and directed radiation from the corresponding directions (top, bottom, left and right) acoustic waves at a frequency ω5in the range of 104-105Hz. Acoustic wave intensity up to 100 W/cm2and more, depending on the nature of the substrate, partially changing the trajectory of the COP on the spray jet out of the coated substrate and pressed the corresponding direction (top, bottom, left and right) KS to a painted substrate. In addition, by analogy with the above being enhanced by the degree of penetration of the COP in the painted substrate with corresponding direction during his stay in the area of the spray jet and significantly improves the fixation of the COP on the surface of the coated substrate.

Simultaneously with the sixth ultrasonic generators, the Torah (43), the sixth amplifier (44) and the sixth DCU air radiator (23) is the formation, increased to the required level and vysokozatratnoe towards moving on the conveyor (22) to the substrate radiation of acoustic waves at the frequency ω6in the range of 104-105Hz.

Acoustic wave intensity up to 100 W/cm or more, depending on the nature of the substrate, partially penetrate into the painted substrate and enhance the fixation of the COP on its surface (pre-commit CC), and also increase due to the transition of acoustic energy into heat energy, the temperature of its surface, which contributes to a preliminary drying gentle drying) with the removal of droplets KS, remaining on the surface of the substrate after dyeing.

Next, painted under the influence of acoustic waves, the substrate with advanced acoustic fixation of the COP on its surface and advanced acoustic drying is fed via a conveyor (22) in the device (24) for final drying of the substrate, and the waste water conduit (25) enters the tank (26) for the treatment of wastewater from BB and HT.

In the vessel (26) using a second device (29) is carried out intensive mechanical mixing of the incoming waste water, and using a second device (30) is created excessive static giving is the giving of 2.5 to 5.0 ATM, speeding physico-chemical processes occurring in the process of waste water from BB and HT.

Simultaneously, using the second ultrasonic generator (34), the second power amplifier (35) and the second DCU sonar emitter (27)located at the geometric center of the vessel (26), is the formation, increased to the required level and omnidirectional radiation of acoustic waves at the frequency ω2in the frequency range 104-106Hz. Hydroacoustic waves affect the waste water and due to physical effects such as cavitation, alternating pressure, and others increase the efficiency of coagulation HT and especially BB.

Simultaneously, using the second generator (50) electromagnetic signals, a second amplifier (49) electromagnetic signals and the second emitter (28) of electromagnetic waves located at the geometric center of the vessel (26) is above or below the sonar emitter (27), is the formation, strengthening and omnidirectional radiation of electromagnetic waves at a frequency ω2in the range of 104-108Hz. Electromagnetic waves also affect the waste water and increase the efficiency of coagulation CENTURIES and especially HT.

In further purified water due to intensive hydrodynamic impact on internal conduit addressed is raised up capacity (26) and the conduit (31) for purified water flows into the reservoir (6) for ultrasonic examination of water activation. While the original BB and coagulated (enlarged) BB (from fine BB and HT) due to the intensive hydrodynamic effects are pressed against the vessel walls (26) and under the action of increased (due to consolidation) gravity slide along the walls of the vessel (26) down and later removed. Under the influence of intense acoustic waves at a frequency ω2and electromagnetic waves at a frequency ω2is electromagnetic acoustic activation of water that significantly increases the efficiency of the subsequent ultrasonic inspection activated water in the tank (6).

When you do this:

1. The expansion of applications is due to the fact that:

- implemented dyeing PM in the air environment that simplifies and accelerates the process of dyeing;

- implemented dyeing PM, not previously painted using spray technology;

- from the waste water are removed not only CENTURIES, but HT (which allows the use of technology in the preparation of drinking water) and other

2. Improving the quality of dyeing is achieved by that:

in the preparation of the COP used a softer water, purified from BB and HT and subjected to a preliminary electromagnetic-acoustic activation in the tank to clean it, as well as the final ultrasonic inspection of the activation of the reserve is re;

- in the preparation of the COP under the influence of hydroacoustic and electromagntic waves, as well as excessive static pressure and intense hydrodynamic field is the complete dissolution of the dye;

- due to collinear (in one direction) with a spray-stream effects of intense acoustic waves increases the penetration depth of CA in the painted substrate;

- due to the bulk acoustic waves improves the uniformity of the CC on the surface of the substrate;

- due to the direct and volumetric effects of intense acoustic waves improves the fixation of the COP on the surface of the coated substrate and other

3. Improving the efficiency of dyeing is achieved by:

- production use only the circulating water by improving the quality of their cleaning from CENTURIES and especially HT;

- reduce consumption of dye and, accordingly, auxiliary substances and water in the preparation of the COP;

- exceptions to process the second (if any) stage of painting substrate;

- reduce the time dyeing of the substrate one of the spray apparatus;

- reduce the time for drying the painted substrate and other

Distinctive features of the proposed device are:

1. The preparation of the COP and its activated derivatives of titsa in the same container (small hydro) for 3-5 min at 20-25°C.

2. In the preparation of the COP and its activation are emitters of electromagnetic waves in the frequency range 104-108Hz.

3. The dyeing of the substrate is carried out in the air chamber through the spray apparatus when collinear (in one direction) distribution of the spray jet and ultrasonic waves with a frequency of 104-105Hz. The first air ultrasonic emitter is located behind the spray device.

4. To ensure bulk dyeing: partial change the trajectory of the COP in the spray stream is clamped to a painted substrate with relevant areas of divergent flow CC), advanced top, bottom, left and right on the painted substrate is carried out ultrasonic testing effects with a frequency of 104-105Hz through the second, third, fourth, and fifth air ultrasonic transducers located appropriately relative to the coated substrate.

5. Additionally, during the movement of the colored substrate on the conveyor to the drying unit is fixing the COP on the surface of the colored substrate by exposure to the ultrasonic wave with a frequency of 104-105Hz using a sixth air ultrasonic emitter, located at the entrance of the drying unit and oriented along the conveyor with a painted substrate.

6. Will add the flax when the movement of the colored substrate on the conveyor to a drying installation is carried out preliminary drying by exposure to the coated substrate DCU wave with a frequency of 10 4-105Hz using a sixth air ultrasonic emitter.

7. Additionally cleaned in the tank (large hydro) of waste water is the impact of electromagnetic waves in the frequency range 104-108Hz, allowing you to clean it from HT.

The presence of the distinctive features of the prototype features allows you to make a conclusion on the conformity of the proposed method the criterion of "novelty".

Analysis of the known technical solutions to detect in these distinctive characteristics have shown the following.

The characteristics of 1,3-6 are new and do not know their use for continuous dyeing PM using waves of different physical nature. When this technology is spray-dyeing (in the sign of 3) is widely known.

Sign 2 is known in the dyeing, but do not know its use for the preparation of the COP and its activation, including in conjunction with DCU waves.

Sign 7 is known, but not known for his collaboration with DCU waves using hydrocyclone for water purification from BB and HT.

Thus, the presence of significant new features in conjunction with the well-known provides the appearance of the proposed solutions new properties that do not match the properties of the known technical solutions is qualitatively: the contrast and the strength of the dyeing, the depths of which Progresa and other and now: the reduction of the COP, reducing the time: dyeing, fixing the COP and drying of the substrate and other PM in an airborne environment, and effectively treat the effluent from the BB and HT with a view to its reuse in production.

In this case, we have a new set of features and their new relationship, and not easy integration of new features and is already known, namely the operations in the proposed sequence and leads to qualitatively new effects. This fact allows to make a conclusion on the conformity of the developed method the criterion of "substantial differences".

An example implementation of the method

Industrial tests of the developed method was carried out in 2007-2008, with the object of dyeing used different types of plastics and other PM.

We know that quality painting PM depends on several factors, the main of which are the quality of the water (its softness and others)used for preparation of the COP; the quality of the CC (the size of the particles and others) and the ability of the COP at the molecular level to evenly penetrate the substrate - object dyeing /B. I. Stepanov introduction to the chemistry and technology of organic dyes. - M.: Chemistry, 1977, 488 S./.

Figure 3 index "a", "b" and "C" respectively denoted graphics based on the arithmetical mean value is tions (P*) diameter (D, μm) particles COP when using the traditional scheme of the preparation (Fig 3,a), using only the ultrasonic acoustic waves - prototype (figure 3,b); as well as the simultaneous use of ultrasonic inspection of hydroacoustic waves (with the possibility of smooth adjustment of frequency in the range from a few kHz up to 100 kHz) and electromagnetic waves (with the possibility of smooth adjustment of frequency in the range from a few kHz to few MHz). In the method prototype in the developed method was carried out prior activation of the water used for preparation of the COP.

As can be seen from figure 3,and the size of particles in KS cooked in the traditional way, is in the range of 1-2 microns to tens of microns, and a typical value is the value ~of 11.2 μm. This fact is the cause of excess dye in the preparation of the COP (part of the dye precipitates and so on), low quality dyeing (COP unevenly distributed on the object dyeing, poorly retained on its surface and so on), the duration of the dyeing process, etc. When implementing the prototype method, the above drawbacks are eliminated not completely. For example, the size of particles in KS is in the range from 0.35 μm to 10.8 μm (Fig 3,b), and a typical value is 0.95 μm. And only in the process of implementation of the developed method of cooking is With (3) above disadvantages are eliminated almost completely. The size of the particles in the COP is in the range from 0.1 μm to 4.5 μm, and a typical value is 0.45 μm.

Figure 4 presents the results of estimation of efficiency of the developed continuous method of dyeing PM (plastic housings for cell phones) using waves of different physical nature in relation to standard method and in relation to the prototype method.

In figure 4,and in the form of histograms shows the dependences of the efficiency of the preparation of the COP (E,%) - defined time duration of 5 main technological stages (stage 1 - submission of dye, water and excipients; stage 2 - mechanical mixing; stage 3 is heated to a temperature of 35-40° C; stage 4 - submission of the COP in the tank for ultrasonic inspection of activation; 5 step - UT effect on the COP within 1-5 min) for the developed method is the histogram with the index "1" (dotted line) and the prototype method is the histogram index "2" (solid line).

As can be seen from figure 4,and, during the implementation of the developed method:

- at the first stage of the technological process time is reduced by ~ 10% due to the reduction of the consumption of dye, water and excipients in the preparation of the COP;

in the second stage of the technological process time is reduced by ~ 50% due to more intensive mixing, and also due to the impact of the DCU guide is Akusticheskie and electromagnetic waves;

the third, fourth and fifth generally excluded from the process because the processes of the preparation of the COP and its activation combined time and are carried out at room temperature.

Thus, the advantage of the developed device before the device is a prototype for selected private performance indicator clearly.

Figure 4,b in the form of histograms shows the dependences of the efficiency of dyeing (E*, %) substrate - plastic housings for cell phones using the spray units defined time duration of 5 main technological stages (stage 1 - initial dyeing; stage 2 - drying; stage 3 - secondary dyeing; stage 4 - drying, stage 5 - fixing the COP on the surface of the colored substrate) for the developed method is the histogram with the index "1" (dotted line) and the standard method of dyeing - histogram with index "2" (solid line).

As can be seen from figure 4,b, the implementation of the developed method:

- at the first stage of the technological process time is reduced by ~ 40% due to the exclusion of two of the five previously used the spray apparatus. This, of course, decreased consumption, KS;

in the second stage of the technological process time is reduced by ~ 20% due to the preliminary drying in a field of intense ultrasonic acoustic waves. However, natural is, decreased power consumption;

the third and fourth stages are generally excluded from the process. In addition, decreased costs COP and power;

- in the fifth stage of the technological process time is reduced by ~ 20% by pre-fixing the COP on the surface of the colored substrate in a field of intense ultrasonic acoustic waves.

Thus, the advantage of the developed method over the traditional method of dyeing of the substrate in air (using spray units) by selected private performance indicator clearly.

Figure 4,presents the values of the turbidity of the water leaving the tank to clean it during the implementation of the developed method (graph with index 1), the prototype method (graph with index 2) and a typical water treatment enterprise (graph with index 3). As can be seen from figure 4,in, the developed method, the turbidity of the water leaving the tank to clean it ranges from 2 to 4 NTU (average 2.57 m NTU), while in the prototype method, this parameter is in the range from 5 to 7 NTU (average 5,86 NTU), and with typical cleaning, this parameter is in the range from 9 to 11 NTU (average 9,86 NTU). Thus, in figv data shows that the effectiveness of clear and sewage with the developed method is much higher.

Thus:

1. The expansion of the scope is reached due to the fact that:

- dyeing PM was carried out while present in the air that this process (the use of spray devices) was significantly simplified, accelerated and did, ultimately, more cost-effective process of dyeing PM;

- was carried out by dyeing PM, previously hard to painted or not painted using spray technology;

- from wastewater was removed not only CENTURIES, but HT, which, in principle, allows to use the developed technology of purification of circulating industrial water even during the preparation of drinking water and other

2. High quality dyeing achieved by that:

in the preparation of the COP were soft water, purified from BB and HT and subjected to a preliminary electromagnetic-acoustic activation in the tank to clean it, as well as the final ultrasonic inspection of the activation in the corresponding reservoir;

- in the preparation of the COP under the influence of hydroacoustic and electromagntic waves, as well as excessive static pressure and intense hydrodynamic field was virtually complete dissolution of the dye;

- due to collinear (in one direction) with a spray-stream effects of intense acoustic waves took what was ivals the penetration depth of CA in the painted substrate;

- due to the bulk acoustic waves improved the uniformity of the CC on the surface of the substrate;

- due to the direct and volumetric effects of intense acoustic waves has improved fixation of the COP on the surface of the coated substrate and other

3. Improving the efficiency of dyeing achieved through:
