The invention relates to equipment for cleaning products using washing liquids in the field of acoustic oscillations.A device for cleaning products containing the tank for washing fluid, and electromagnetic means for creating vibrations and heating the liquid.A disadvantage of this device is the high energy consumption associated with low efficiency of energy conversion of electrical current into the energy fluctuations.The technical result of the invention is to reduce energy consumption.This result is achieved by the fact that the device for cleaning products containing a bath of washing liquid and a tool for generating vibrations according to the invention a tool for generating oscillations made in the form placed in the bath bubbler having a weekend supersonic nozzle and communicated with through the possible energy to the energy of ultrasonic oscillations at least 50 times.In a preferred embodiment, the inputs in the bubbler nozzle swirler installed.This allows to further reduce energy intensity by increasing the power of the generated oscillations at a constant Energobud.In another preferred embodiment, between the means for supplying gas and bubbler installed pulsator.This leads to the achievement of the same result for a similar reason.The last preferred embodiment of the present invention is provided for installation between the means for supplying gas and bubbler heater.This allows for clearance of goods at controlled temperature, expanding the technological capabilities of the device, this is achieved efficiency of heat transfer is higher than the closest analogue.In Fig. 1 shows a diagram of the device of Fig. 2 and 3 show embodiments of the nozzles of the bubbler.Device for cleaning products contains 1 bath for washing liquid placed in it bubbler 2 connected with 3 gas supply directly, or through the pulsator 4 and/or the heater 5. The outlet of the bubbler 2 made in the form of STV purified product is placed in the bath 1, filled with washing liquid, and means 3 creates a gas bubbler 2. In nozzles 6 gas reaches a supersonic speed and output of them creates turbulent breakdown, accompanied by the formation and collapse of cavitation cavities, especially when pulse mode feed gas that is generated in the presence of the pulsator 4. In the presence of the swirler 7 supersonic swirling gas flows at some distance from the exit nozzle 6 retain the barrel-shaped form and create a regular jumps seals in units of barrels to crushing on a separate bubbles. Efficiency of energy conversion into energy of ultrasonic vibrations in such a way to create them according to the calculation and experimental data validation reaches 40-60%, while the creation of acoustic oscillations using high-frequency current does not exceed 1,5%.If necessary, heat the washing liquid, in particular when cleaning metal products from oils in alkaline solution prior to plating or wash in soapy water, milk jars, between the tool 3 gas supply and bubbler 2 is advisable to install the heater 5. In this case, the gas is used as coolant. In the process field of ultrasonic oscillations of the gas reaches equilibrium temperature, that is completely transmits the resulting quantity of heat of the liquid. This is confirmed by theoretical calculation, under which a characteristic of the process of the contact phase Reynolds numbers in the range from 100 to 1000 averaged over time in the number of Nusselt reach values of 15-20. At the same time, it should be noted that the dissipative heat in the electromagnetic vibrators are transmitted washer fluid a maximum of 45%.Under the action of ultrasonic vibrations to the liquid in the cleaning products be self-oscillations, the frequency of which depends on the physical properties of the products, in particular on the density and elastic modulus. Pollution, as a rule, differ sharply on these parameters from the material of the purified product, therefore, is the detachment of contaminants from the products due to desinfecte natural vibrations of their mating surfaces. This leads to an increase in the rate of separation of the impurities is higher than the value determined by the solubility of the contaminant in the used washing liquid with regard to the acceleration of mass transfer in the field of ultrasonic vibrations. It should be noted that from the surface are removed even pollution, is not soluble in the used washing idcol in hot water is flushing mineral oils and scale.Thus, the proposed device allows to reduce the energy intensity of cleaning products, increase productivity and quality of treatment, to make cleaning under controlled temperature conditions. 1.
