Method cleaning products

 

The invention relates to cleaning products with geometrically-complex surfaces. The method consists in the fact that the product is poured detergent solution, which serves the gas circulate solution, rinse liquid, produce a drying gas. When this processing detergent solution, rinsing are in continuous streams incohesive mixtures in which the gas is distributed in the form of bubbles, and in the process change the gas concentration, bubble size, the concentration of gas bubbles in different factions, and in all cases, use only the cleaned gas. The method provides an improved quality of cleaning and its speed, and also eliminates the leaching of toxic solvents. 3 C.p. f-crystals, 1 tab., 1 Il.

The invention relates to the purification of the products from contamination mainly with complex profiles of surfaces.

The known method of cleaning products (see Kratos E. B. and other "Equipment cleaning products in mechanical engineering". M: mechanical engineering, 1969, S. 81-82), in which the parts are cleaned hot and cold solvents, washing, drying. The disadvantage of this method is that it is environmentally harmful, because it involves the use of toxic solvents, malouff patent RU 2058430, class C 23 G 5/02, 20.04.1996, namely, that the product is treated in the washing solution, which serves the gas circulate solution, rinsed with water and produce air drying. This method is less harmful, because the cleaning is done in an aqueous detergent solution, rinsing in water, and the cleaning quality is significantly improved by introducing a gas into a liquid.

The disadvantage of this method is its low efficiency in cleaning products complex inner or outer shape having cavities, pockets, slits, which are arranged at an angle to the flow axis (details). The processing time is relatively simple parts large (several hours).

The technical result is to increase the quality, speed cleaning geometrically-complex products and the exclusion of leaching toxic solvent.

This objective is achieved in that in the method of cleaning products, which consists in the fact that the product is poured detergent solution, serves the gas circulate solution, rinse liquid, and then produce the drying gas: processing detergent solution, rinsing are in continuous streams incohesive mixtures in which the gas is distributed in the form of bubbles, and in the process izmenyautsya use only the cleaned gas.

The invention consists in that the processing in the flow IGS products with geometrically-complex surfaces can improve the process of separating impurities, because the gas bubbles act as a "brush", and give the thread GGS vector rotational motion allows you to spin the thread, to strengthen its turbulization and contribute to hydrodynamic cavitation. Changing the magnitude and direction of vectors, translational and rotational movements of the thread give it a pulsation (oscillatory motion), which reinforces the separation of the impurities attached to the surface.

The drawing shows a diagram of the inner surface of geometrically-complex tubular goods.

In this way the cleaning is produced as follows.

The inner cavity 1 product 2 serves heated to 60...90oWith GGS detergent, such as water + CMC (detergent OCA) + bubbles pre-cleaned gas (air, argon), missed advanced through the ceramic filters, which provide the formation of gas bubbles of a certain diameter, depending on the size of the pores of the filter. The gas bubbles uniformly saturate GIGS and create a unique brush "ruff", where the fibers are the bubble is the following different pore size. In the modified cleaning. Large bubbles clean off large particles and provide macroturbulence thread, but can't penetrate into the slit, the angular cavity, shallow basin, sink with dirt. The small size of the gas bubbles can cause artificial cavitation and to penetrate into the slit hard-to-reach places. The effect of "ruff" is ensured by the fact that the gas bubbles, pushing each other, create a chaotic motion and transmit impulses amount of movement to each other, resulting in the boundary with the inner surface parts (pipes, for example), where the velocity of the flow is lower than in the Central part of the tube, the activation of the thread formed microwire, resulting in including hydrodynamic cavitation, producing a cleansing effect. Changing the amount of feed gas into a liquid, it is possible to regulate the process of turbulence and hydrodynamic cavitation flow GIGS, and alternately switching the filter element, through which feed gas, it is possible to change the size of gas bubbles, to influence the process of artificial cavitation. At the same time feeding through porous filters with different pore sizes different amount of gas, you may receive and fluid change from 20 to 30% (create a ripple of the stream), the concentration of various fractions of gas bubbles per unit volume of gas GGS also change (see table at the end of the description).

In the cleaning process may change according to certain laws in time of the total concentration of gas bubbles Kg=f(T), the concentration of gas bubbles per unit volume of gas GIGS in a separate fractions of Cfi=f(T), the vector of axial translational motion V0=f(T). The optimal mode is determined for each cleared product. The change of the velocity vector V0it is possible to create a pulsating flow IGS (oscillatory motion along the axis of the thread) and even to periodically change its direction, which creates microwire different directions, the zone of negative pressure at the surface, cavitation with high destructive capacity for contaminants, and the purification of the product is improved. The pulse frequency and the law of its variation can be adjusted, for example, regulating the pump and the valve associated with the control unit, which is connected with a gas dispenser and dosing of the individual fractions of gas. Possible other embodiments of this method. Particularly well cleaned complex surface directed along the axis of the product (stream IGS).

If the stream EGS to inform the vector Krasotka in the border to the walls of the pipe region is amplified, there is an active turbulization of the flow GIGS and given it a spiral movement with high total tangential velocity near the pipe wall, with well-treated cavities, cavities, slits, located at an angle (perpendicular) to the axis of the part. Changing the direction and magnitude of the vector Vp (create a ripple, the oscillatory motion in a spiral flow IGS), it is possible to achieve fast and high-quality purification of the product for which the application of the method described above is less effective. Technically implement the swirling flow is possible with the help of various elements with helical surface, adjustable blades, changing the direction of flow, special turbine installed on the flow axis, which are connected with the control unit.

Thus, comprehensively changing the velocity vectors axial and rotational flow GIGS in combination with a change in the characteristics of the gaseous portion of the mixture, it is possible to intensify the process of cleaning various complex areas of the product - hollows, crevices, cavities, curves, protrusions, having a complex topography and spatial orientation relative to the Central axis of the product, which in other ways impossible to clean or don is to provide fast and high-quality cleaning difficult surfaces from salts of fatty acids and residues of washing solution to these operations, this also regulate Vo, Vp, Kg, KFi. When this operation is completely eliminated leaching of toxic solvent, since the intensification of the process of rinsing ensures quality by removal of residual cleaning solution and salts of fatty acids. This method is environmentally friendly and not harmful to humans.

Of particular note is the feature of this method is that for all operations and especially the operation of drying the applied gas (air) quality cleaning from mechanical and chemical impurities in the form of organic compounds (oils, phenols and others), because otherwise, at the stage of drying and rinsing possible secondary contamination of the product by dust particles, oil and other contaminants.

The above-described method of processing internal geometrically-complex surfaces. For treatment of external geometrically-complex surfaces the product is placed within the stream IGS, for example in the pipe, the internal diameter of which is greater of the two dimensions of the product, and the third overall size of the feature along the pipe axis and served in the pipe GIGS by the above method with the regulation of the parameters of the flow rates and composition of the gas mixture components, that provides high quality and speed of treatment iodine, food routes, blocks, air separation, gas, oil systems, devices, components with very complex external and internal configuration of the surface.
