SU889692A1 - Apparatus for washing fusel oil - Google Patents

Description

The invention relates to food perfection, in particular to apparatuses for the production of fusel oil. A known apparatus for pouring fusel oil contains a vertical column with nozzles for supplying fusel oil and draining water, horizontal plates mounted inside it with central overflow pipes and hydraulic locks and located in the upper part of the column a detonator-sump with pipes for water supply and suction of fusel oil 13 However, this device does not provide an opportunity to increase the degree of fusel oil purification. The purpose of the invention is to increase the degree of purification of fusel oil. This goal is achieved by the fact that, in an apparatus containing a vertical nougho column with branch pipes for the supply of fusel oil and water drainage, horizontal plates installed inside it with central overflow pipes and water seal and located in the upper part of the column a decant-settler with branch pipes for supplying water and branch pipe fusel oil, each odd plate on top of the column is equipped with an additional overflow tube with a contact cap, the latter being installed in the central overflow tube and its lower section It is placed under the water seal, and the upper cut with the contact cap is above the odd plate, with each even plate being equipped with additional overflow pipes installed along its periphery so that their upper sections are located under the well-lying odd plate. In addition, the water outlet pipe is equipped with a water seal, which is flattened at the level of the settling decontactor, and each contact cap and water seal of the overflow pipes are made in the form of a glass with a truncated perforated cone, with the free section of the perforated truncated cone increasing from its central part to the periphery. FIG. 1 shows schematically an apparatus for washing the fusel oil, a general view; in fig. 2 - columns and contact plates, vertical section. The device consists of the following main components and parts. In the vertical rock column 1 horizontal horizontal plates 2 are installed. Each odd plate 2, starting from the top, is fitted with a Contact cap 3 and an additional perelivnaya. tube 4, which is passed through the central tube 5 and the hydraulic lock 6. Each even 2 is provided on the periphery with additional transfer pipes 7 and in the central part with an overflow pipe 8 and a hydraulic lock 9. Such arrangement of transfer pipes, hydraulic pipes 4 and 8 9 creates a diagonal movement of the interacting flows, thereby increasing the contact time, and also maximizes the volume of the contact stage for the interaction of the phases and provides for alternate crushing in terms of the general counterflow.

In the upper part, the column 1 is equipped with a decanting settler 10, as well as a hydraulic shutter 11 installed at the level of the decoupler 10.

The device also has connections, respectively, for the supply of raw fusel oil. 12, for the supply of water 13, for the removal of wash water 14,. For the removal of purified fusel oil 15.

To crush the streams into separate jets and evenly distribute them throughout the contact stage, the contact caps 3 and the caps, hydraulic gates 6 and 9 are made in the form of glasses with truncated perforated cones 16. The free cross section of the perforation in the cone 16 increases from the central part to the periphery . For the removal of air from the system apparatus, equipped with air vent 17 and 18.

AnnatJaT works as follows.

Water is supplied through nozzle 13, and moves down column 1 under the force of gravity. Crude fusel oil enters column 1 through nozzle 12 and rises up due to Archimedes forces. Having reached the bottom (even) plate, the oil flows over the flow pipes 7 under the overlying odd plate. Here it accumulates and stays until those feathers until a layer is formed under this odd plate, the lower level of which reaches the lower section of the additional overflow pipe 4. The washing water is fed into the oil layer through the central overflow pipe 5 with a hydraulic block 6 and is distributed throughout the cross section of the column with the help of a cone 16 in the form of separate jets. The latter move in the oil layer accelerated by the force of the tin. This leads to their fragmentation into individual drops, which increases the contact surface and the turbulization of the interacting flows.

The water that has been contacted with the oil is collected below the lower section of the additional overflow pipe 4 and drained to the underlying plate through the central overflow pipe 8 with a hydraulic seal 9.

Oil from under the lower odd plate (from the lower volume of the layer) is squeezed out by Archimedes forces through an additional overflow tube 4 into cap 3 and distributed over the cross section of the column 1 above the lower odd plate using a perforated cone 16. These jets of oil move upwards accelerated under the action of forces Archimedes and due to this fraction is divided into separate drops, increasing the contact surface. The droplets move in a layer of water, entering through the central overflow tube 8 and the water seal 9. from the overlying plate and are subjected to intensive washing. Under the second bottom of the odd plate, drops of fusel oil are collected in the film and discharged through additional overflow tubes 7 upward under the next odd plate, where the process of moving water and oil is repeated, etc.

The purified oil is discharged from the glass washer through the decontamination tank and the pipe 15. The resulting wash water is discharged from the apparatus through the hydraulic lock 11, which is installed at the level of the settling decontactor 10, which allows to create a solid layer of water between each underlying odd and overlying even plates.

The fuselwash rinsing unit provides alternate crushing of fusel oil and water in the presence of their common countercurrent in column 1. With an atom under each even-numbered plate, a constant layer of water accumulates, and under an odd one, a fusel is attached. The thickness of the layers of water and oil does not depend on the flow of the phases. The latter reduces the dependence of the intensity of the interaction of phases on their consumption and. provides in all modes of operation of the apparatus constant contact time of water and oil.

The organization of alternate crushing of phases in combination with the accumulation of layers of water and oil under certain plates eliminates bypass zones, maximizes the use of the contact volume of the device, and increases the time and surface of the contact, which makes it possible to increase the level of fusel oil purification.
