Abstract

Usage: the invention relates to the oil and fat industry, and more specifically to the technique of hydrogenation of vegetable oils and fats. SUMMARY OF THE INVENTION: The device consists of hydrocyclones connected by supply nozzles with a chamber 3 for the passage of the initial liquid substance, inside of which there is a parabolic flow guide 4. The mixture is fed through a flange 5 supply nozzle, the outlet nozzle 6 is installed with a rotation of 180 °. and is intended to transfer the clarified slurry into the HVRDE chamber 7. After exiting the hydrocyclones, the thickened suspension of the catalyst enters the annular inclined chute and is directed through reuse 9 through pipe 9. 1 il.

Description

The invention relates to the oil industry and can be used to separate the catalyst from salomas during the hydrogenation of oils and fats.

The purpose of the invention is to improve the distribution of salomas with a catalyst over hydrocyclones,

Improving the distribution of salomas with a catalyst over hydrocyclone elements is achieved by placing a flow guide, which is a paraboloid of rotation, in the passage chamber of the initial mixture. The circle formed by the rotation of the focus of the parabola coincides with the circle of the radius of the chamber for supplying salomas with the catalyst.

The use of a flow guide allows one to use the well-known property of the paraboloid and. the connection of flows directed to its surface on a circle formed by the rotation of the focus around the axis, with intensive, turbulent mixing of the suspension in this zone. This design reduces the formation of stagnant zones in the cylindrical passage chamber of the original liquid substance.

The drawing shows a device section.

The device consists of hydrocyclone elements 1 connected by nozzles of the inlet 2 with a vertical cylindrical chamber of the passage 3 of the initial liquid substance, inside of which there is a parabolic flow guide. The initial liquid substance is fed through a supply chamber 3 with a flange 5 to the hydrocyclones 1. The flow guide 4 has the shape of a paraboloid of revolution and is placed with its apex towards the flow of a liquid substance (salomas with a catalyst). The inlet pipe 2 of each hydrocyclone 1 is located in the focus of the parabola of the flow guide 4. The collection and removal chamber of the clarified component 7. is connected to the nozzles 6 of the clarified component of the hydrocyclones 1, which are rotated 180 °. The chamber 7 is located under the passage chamber 3 of the initial liquid substance 4, has a common end wall with it. The collection and withdrawal chamber of the thickened component 8 is made in the form of an inclined annular tray and mounted on the outer side surface of the cylindrical output chamber of the clarified product 7. The thickened catalyst suspension, after exiting the hydrocyclones 1, enters the annular inclined tray 8 and is sent for reuse through the pipe 9.

The device operates as follows.

Salomas from the salomassage is sent through a pipe with a flange 5 into the passage chamber of the initial catalyst suspension in salomass. In parallel, moving salomas with a catalyst are reflected on the surface of the parabolic flow guide and are distributed with vigorous stirring at the inlets of 2 hydrocyclone elements 1. After separation in hydrocyclones 1, the clarified suspension with a concentration of 0.9-1.2 kg / t in terms of nickel passes through pipes 6 into chamber 7 and is sent after polishing filtering for implementation.

The thickened suspension with a concentration of 30-40 kg / ton from the lower drains of the hydrocyclones 1 is sent to an inclined annular tray 8 and, under the action of gravity, slides to the nozzle 9, through which it is returned to the agitators with a passport catalyst for rehydrogenation.

The use of separation in the proposed device provides separation of the catalyst, from M1 grade salomas to a residual nickel content of 0.9-1.2 kg / ton in the clarified product and 30-40 kg / ton in the condensed product.
