As you can see in the attached drawings, the vertical vessel 2 and podogreva camera 3 have a common longitudinal axis 8, on which are located the upper end 5 and the lower end 7 poderevnoy camera 3.

The device 1 includes consistently placed one above the other heating pipeline system 9, 10 and 11, located inside poderevnoy camera 3. In the variant illustrated in pilage the current profile should be clear, their numbers may be different, such heating pipeline systems can be from one to five or more, depending on the needs of a particular application. Except for orientation in space, as will be described below, the heating pipeline system 9, 10 and 11 are identical. Therefore, for the sake of convenience hereinafter will be described only the heating pipeline system 9.

Heating pipeline system 9 includes made in the form of coils of the heating tubes 12 and 13. These heating tubes 12 and 13 are identical except for orientation, which will be discussed below in more detail. Therefore, we will describe only the heating tube 12. As can be seen in Fig.4, the heating tube 12 has a U-shaped curved sections 14 and straight connecting sections 15 through which implemented the connection of the U-shaped bent sections 14 between them, as shown in Fig.4.

This is true for all planes, which are made in the form of coils of the heating tubes 12 and 13, which is formed by heating pipeline system 9, 10 and 11 of the device 1. Thus, as can be seen in Fig.2, each of the heating tubes 12 of the heating pipeline systems 9, 10 and 11 is located in a plane in close proximity to the parallel plane in which is located the heating enterprises.

The heating tubes 12 and 13 are arranged so that the input channel 19 of the heating tube 12 is located next to the output channel 20 located next to her heating tube 13 and Vice versa, so the direction of flow of the liquid coolant supplied through the input channel 19 of the heating tubes 12, in the respective heating pipeline system is opposite to the direction of flow of the liquid coolant supplied through the inlet channels 19 of the heating tubes 13, and Vice versa. For the average specialist in the field will not be difficult to find such a topology heating pipeline systems, which will be provided for the liquid coolant alternately in one direction then in the opposite direction, thus minimizing non-uniformity of temperature distribution on the square poperen the main chamber 3 thus, what possible movement of the solution of polymer in solvent received in a vertical tank 2 through the inlet channel 4, down through podogrevom camera with 3 providing heat exchange contact of this solution with the outer surfaces 12A and 13A of the heating tubes 12 and 13 as the flow of solution in the direction shown by the arrows 23, that is, generally along the longitudinal axis 8 from the input channel 4 poderevnoy camera 3 to its outlet opening 6.
