SU760518A1 - Apparatus for degassing liquid - Google Patents

Description

The invention relates to a device for removing free and partially dissolved gases from liquid media and can be used for. degassing of photo emulsions, epoxy resins, oils, in the manufacture of plastic products, glass, etc.

A device for degassing liquids in a stream using ultrasonic vibrations is known, which includes a tank with a number of vertical partitions that do not reach the bottom, a tank bottom equipped with ultrasound transducers, and the bottom, the edge of all partitions and the distances between them are determined by a quarter-multiplicity of the ultrasonic wave.

The closest in technical essence and the achieved result “Is * the device“ For deG'Azation ”of a liquid, including a housing with a bottom, vertical partitions that do not reach the bottom, an ultrasonic transducer installed under the bottom, 25 ″ plate of sound-absorbing material, input, outlet and drainage pipes.

The disadvantage of the known device is that it is necessary to reduce the gap between the bulkheads and the bottom with a dv ^ Ί in the junction ^Λ ty *, which is conducive to a decrease in the amount of liquid escaping. If you extend the path of the fluid over the surface emitting ultrasonic waves, adding: high quality degassing, then the dimensions of the device increase, which when used in some cases is not desirable due to lack of production space.

The purpose of the invention is to increase the degree of degassing while reducing the size of the device.

To this end, the body is made in. a spiral channel with a constant cross section, and the inlet pipe is half centered in the center of the helix ^ ’It is advisable to make the bottom removable and the ultrasonic transform. The receiver must be equipped with a clamping mechanism. „

Figure F shows the device in section; FIG. 2 is a section A-A in FIG. one. ..

The device contains a spiral. housing 1, bottom 2, ultrasonic transducer 3, Podzhim mechanism 4, inlet 5, vertical

partitions 6, plate 7 of sound-absorbing material, output 8 and drainage 9 nozzles, gasket 10. ¹ -

The device works as follows.

Subject to degassing is supplied to the center of the bottom is in contact with the ultrasonic transducer 3. Through the inlet 5, the liquid enters the spiral casing 1, spreads in a spiral, filling the device.

At the same time, under the action of ultrasonic oscillations, the degassing process takes place, the transition of the dissolved gas to free gas begins and new gas bubbles are formed, which under the action of the acoustic forces of Bjerkness and the hydrodynamic Bernoulli force intensively unite, their sizes grow, respectively, and the ascent force increases. Moving from the lower liquid layers to the upper, gas bubbles are trapped by vertical partitions 6 and rise to the liquid-gas interface, and the released gas is removed through the drainage pipes 9. The gas cleaned from the gases is fed to the consumer through the outlet 8. Plate 7, which is a non-emitting bottom surface, is installed under the last partition. In this area, single gas bubbles are removed that form on the edge of the exhausting surface. Ultrasonic vibrations are transmitted to the bottom by ultrasonic transducers, which are pressed to the bottom by a pressing mechanism, and the bottom, respectively, through the pads 10 of sound-absorbing material is pressed to the lateral surface of the housing.

The device allows to improve the quality of the degassed liquid due to the fact that the time spent for the Liquid in the ultrasound coverage area increases, which makes it possible to degas liquids of high viscosities without decreasing the productivity. Due to the spiral course, the dimensions of the device do not increase, and with low energy costs, it is possible to achieve high-quality operation of the device, which in the end result will improve the quality of the product.
