DESCRIPTION:
BRIEF SUMMARY
Technical Field
The present invention relates to a method for acceleration of liquid and bulk materials and an apparatus for carrying out the method.
Prior Art
Widely known nowadays is the use of acceleration for treating various materials by centrifuging. In this method the acceleration produced are limited by the structural elements of the centrifuge (drive, shaft supports, etc.). Besides, acceleration of the material in the centrifuge basket takes a certain time. Thus, on the one hand, the treatment intensity is restricted by the limited value of acceleration and, on the other hand, productivity is rather low due to the necessity for accelerating and retarding the centrifuge.
There is also a method for treating liquid and bulk materials wherein the treated material is accelerated by electromagnetic pulses. For this purpose the treated material is placed into a container and the pulses are applied to the container bottom. This produces elastic deformation in the bottom so that the particles of the treated material are accelerated and start moving relative to one another (SU, A, 775559).
A disadvantage of such a method is the considerable energy losses of the electromagnetic pulses required for elastic deformation of the container bottom. The obtained accelerations are extremely low (2-5 g) which denies the possibility of intensifying the process of treatment.
Brief Description of the Invention
The object of the present invention is to provide a method for acceleration of materials being treated wherein the electromagnetic energy is converted into mechanical energy with a minimum of unproductive losses and also to provide an apparatus for carrying out the method.
The objects are achieved by providing a method for acceleration of liquid and solid materials by converting the energy of the electromagnetic pulse of a radiator into mechanical energy applied to the treated material wherein, according to the invention, the energy of the electromagnetic pulse is converted into mechanical energy by a plate-like element an electrical conducting material possessing at least one degree of freedom in the preset direction of acceleration and wherein the opposite surfaces of the plate element at the moment of pulse emission by the radiator is in physical contact with the radiator and the material to be treated, respectively.
Though it is no wish of the author to give theoretical substantiation to the physical phenomenon observed in operation of the disclosed method for acceleration of liquid and bulk materials, it may be presumed that ultra-high accelerations (a few thousand "g") are obtained by inducing a secondary field in a plate element, said field interacting with the primary electromagnetic field of the pulse radiator which produced a high-energy mechanical pulse. The arrangement of the plate element with at least one degree of freedom in the preset direction of acceleration, eliminates the expenditure of electromagnetic energy of the pulse for elastic deformation of the material interposed between the radiator and the material to be treated.
The effect of the disclosed invention is quite unexpected. Thus, in the course of experiments the material weighing eight kg was thrown up 3-4 m high by an electromagnetic pulse energy of a few joules.
The material to be treated can be water flowing onto one surface of the plate element while the electromagnetic pulses are emitted in a continuous mode.
The method also can intensify the cooling process in, say, cooling towers and other heat-exchange apparatuses.
The material to be treated can be biological material to be sterilized.
In this method the biological material is placed on one surface of the plate element.
Materials can be mixed by the flows of directing the various materials to be mixed onto the surface of the plate element. The method increases the productivity and completeness of mixing.
It is preferred that the leading edge of the pulse should be defined by the pulse rise time amounting to 10-20% of pulse duration. This ensures the maximum energy capacity
