Description

one

The invention relates to devices for mixing and homogenizing immiscible and hardly mixing liquids, mixing liquids and gases. It can be used in those sectors of the national economy in which the processes of heat and mass transfer and mixing of components are carried out, for example, in the petroleum industry to obtain micellar solutions, emulsions and microemulsions by mixing two or more components.

The purpose of the invention is to increase the displacement efficiency of components and the quality of the mixture.

The drawing shows the proposed device, the cut.

A device for mixing comprises a housing 1 rotatable and made in the form of rotation bodies; the annular nozzle 2 placed therein is connected to supply lines 3 and 4, an offset chamber 5 made in the form of two annular disks 6

which are connected to the peripheral part of the housing 1. The leading

The conduit 4 of the annular nozzle 2 is connected to a rotational drive (not shown). The annular nozzle 2 has overflow pipes 8 and vanes 9. Case 1 also has vanes 10 and is connected from two halves with screws 11.

The device works as follows.

To obtain a homogeneous mixture of the two components, the device is rotated and the mixed components are fed through the supply pipes 3 and 4. One of the components is fed through conduit 4 into the cavity of the annular nozzle 2, in which, due to centrifugal forces, the component is accelerated and through the outlet of the annular nozzle 2 enters the mixing chamber 5. The other component is fed into the cavity of the housing 1 through conduit 3 and the by-pass nozzles 8. The component is also accelerated by the centrifugal forces in the cavity of the housing 1, which is favored by the blades 10 (like the blades 9 in the annular nozzle 2), after which the component is thrown into the mixing chamber 5. In this chamber the two components are mixed suhl

A homogeneous mixture is formed which is then supplied to the consumer.

As a result of using the annular mixing chamber with a variable distance 5 between the walls of the flow part, i.e. between the annular disks radius 5 in the centrifugal ejection mixer of the proposed design due to the optimization of the condition

VII mixing of components improves the quality of mixing (due to the narrowing of the distribution of emulsin droplets in size due to constant conditions of constraint and mixing of components along the entire length of the mixing chamber), the resistance to delamination increases (due to a more uniform distribution of the concentrations of components in a volume of 20 mixtures), These advantages result in obtaining a positive technical and economic effect in the preparation of mixtures by eliminating the need for repeated 25 or repeated yeshivan

the mixture and its further use in technological processes due to the high quality of the mixture and its sustainability,

The application of the proposed technical solution will make it possible to increase the efficiency of the mixing of the components and to obtain a mixture of high quality due to the use of a more advanced design of the mixing chamber, which ensures the implementation of highly efficient mass transfer processes.

Due to the fact that the mixing chamber in the proposed device has a constant annular cross-sectional area along the entire length of the chamber, expressed by the H NoCoR dependence, where the initial distance between the annular disks of the chamber, H is the distance between ring discs along the radius, RO is the initial radius of the circumference of the annular discs of the displacement chamber, R is the radius of the circumference of the external annular discs, it mixes and mixes the components in the mode of their hard contact, increasing the efficiency of processes
