Description

The utility model relates to devices for separating mixtures of liquids with different boiling points, carried out by distillation, in particular, to the design of a flow-through distiller.

LEVEL OF TECHNOLOGY

Currently, the separation of mixtures of liquids with different boiling points (different boiling points) is carried out by distillation - by gradually heating the distillation mixture to the boiling point of its components, further condensation of vapors on the walls of the refrigerator and separate collection of these liquids into receivers.

A device for the distillation of mash is known from the prior art, comprising an evaporation vessel for heating and vaporizing mash, made in the form of a container with a conical bottom, a refrigerator for running water, and a collection of the finished product. The conical bottom of the refrigerator is made in such a way that the top of the cone is directed upward, a conical hole is made in the upper part of the conical bottom, in which an elastic elastic conical plug is installed with a hermetically sealed thermometer, an annular collecting container is placed in the lower part of the cone along its periphery from the inside , the outer side wall of which is formed by the conical surface of the bottom of the refrigerator, the inner side wall is formed by a branch pipe connected to the evaporator tank, the bottom of the annular collecting tank is hermetically welded to the branch pipe and to the conical bottom and is equipped with a fitting connected to the removable collection of finished products, on the side surface of the conical bottom in its upper part has a hole in which the inlet end of the coil placed inside the refrigerator is hermetically welded, the outlet end of which is hermetically welded to the outer side surface of the refrigerator and is equipped with a fitting communicating with the collection of finished products and installed in a holder fixed at the outlet end of the coil with the possibility of its removal (patent RU 2 255 973, C12G3 / 12, publ. March 27, 2005).

As a rule, during the distillation process it is necessary to heat the entire volume of the existing mixture and then separate it into components. The disadvantage of this type of distiller is the impossibility of providing a continuous flow of the separated mixture of liquids through the distiller.

USEFUL MODEL DISCLOSURE

The technical problem solved by the present utility model is to propose a distiller that separates a mixture of liquids passing through said distiller in a continuous flow.

According to the utility model, the flow-through distiller contains an evaporator connected to a heater and a refrigerator with a collecting container for distillate located inside at its base in the form of an inclined chute. The evaporator is made in the form of a cone connected to a heater and is located inside a cylindrical refrigerator, which can be cooled in different ways. The cylindrical cooler is closed from above with a lid with a central hole through which a branch pipe passes, designed for continuous supply of the initial mixture of liquids with different boiling points to the surface of the evaporator. The collecting container for the distillate is made in the form of an inclined annular chute adjacent to the inner surface of the cylindrical refrigerator. A funnel is placed under the evaporator to collect the non-evaporated mixture of liquids.

The device may contain at least one additional distiller, sequentially located downstream of the mixture of liquids with different boiling points.

The set of essential features described above ensures the achievement of a technical result consisting in a continuous process of distillation of a stream of a mixture of low-boiling liquids.

The use of a flow-through distiller according to the utility model makes the distillation process continuous with a constant yield of all fractions during distillation with regulation of the amount and purity of the separated components. The distillation process ceases to be cyclical and turns into a continuous one.

BRIEF DESCRIPTION OF THE DISTILLATOR

The utility model is illustrated by a drawing, which shows an embodiment of a flow-through distiller.

IMPLEMENTATION OF THE USEFUL MODEL

As shown in the shown drawing, the flow-through distiller comprises an evaporator 1. The evaporator 1 is made in the form of a hollow cone connected by pipelines to the heat exchange circuit 2 with the heater 3. The evaporator 1 and the heat exchange circuit 2 are filled with an appropriate liquid, which provides heating to the required temperature. The evaporator 1 is located inside the cylindrical refrigerator 4. The walls of the refrigerator 4 are hollow. The refrigerator is cooled by running water through the pipes fixed on it. The cylindrical refrigerator 4 is closed from above by a lid 5 with a central hole through which a branch pipe passes, designed for continuous supply of the initial mixture of liquids with different boiling points to the surface of the evaporator. At the base of the refrigerator 4 there is a collecting container for the distillate. The collecting container is made in the form of an inclined annular trough 6, adjacent to the inner surface of the cylindrical refrigerator 4. In the lower part of the trough there is an outflow for collecting the distillate (condensate) into the receiver. A funnel 7 is placed under the evaporator to collect the non-evaporated mixture of liquids.

When using several distillers of a similar design, the funnel for collecting the unevaporated mixture of liquids at the previous stage of the technological process is connected to the inlet of an additional distiller located in series.

DISTILLATION PROCESS

The process of separating mixtures of liquids with different boiling points is carried out as follows.

Through the central hole in the lid 5 through the branch pipe, the initial mixture of liquids is continuously supplied to the conical surface of the evaporator 1. The evaporation of lightly boiling fractions from the mixture of low-boiling liquids on the surface of the evaporator 1 and subsequent condensation of the resulting vapors on the inner walls of the refrigerator 4 located around the evaporator 1. Condensate (distillate) flows down the walls of the refrigerator 4 and enters the inclined chute of the collecting vessel, through which it is discharged from the distiller through an outflow in the lower part of the chute and is collected in a corresponding receiver. Unvaporized liquid, washing the evaporator 1, flows into the receiving funnel and is removed.

When using multiple continuous flow distillers, unvaporated liquid is fed to the inlet of the next downstream additional distiller. All evaporators in continuous flow distillers in a multistage process must be thermostated to a certain temperature corresponding to the boiling point of the component to be separated. Thermostating of the evaporators can be carried out, for example, by the boiling point of the liquid inside the evaporator or by an electronic thermostat that controls the electrical heating of the evaporator. The boiling point of the liquid inside the evaporator can be controlled by varying the atmospheric pressure within the heating circuit or by mixing the liquids eutectic to lower or increase the surface temperature of the evaporator. The temperature in the refrigerator can also be controlled to control the condensation of the various components of the distillation mixture.
