Abstract

The invention relates to heat exchange and may be. used in apparatus for heating highly viscous liquids. The invention allows to intensify heat transfer and increase operational reliability. Heating steam under pressure through fitting (Ø) 13, mounted concentrically to discharge Ø 14, enters the cavity of compartment 9 of the rotor disk of the PSA) 5. The latter rotates with the help of shaft 4. At the same time, part of the steam goes through nozzles 12 in the fixed partition 7 redistribution in compartment 8 of the taxiway. The condensate formed at the same time on both inner walls of the RD 5 is thrown by the centrifugal forces to the periphery of the internal cavity of the RD. Rotating along with the RD 5, the condensate enters the curved channels of the partition 7 formed by the walls of the flat disks 10 and the profiled lobes. Condensate is discharged through W. 14. The heated coolant is supplied into the space between housing 1 and RD 5 simultaneously to both disk surfaces of the latter closer to the center of its rotation. 1 ap f-ly. 4 il.

Description

The invention relates to heat exchangers designed to heat highly viscous liquids, in particular lapralones in chemical production, and can be used in various industrial sectors.

The purpose of the invention is the intensification of heat exchange and the increase in operational reliability.

FIG. 1 shows a heat exchanger cross section} in FIG. 2 shows section A-A in FIG. one; in fig. 3 is a view B in FIG. 1, in FIG. 4 - partition, side view.

The heat exchanger comprises a housing 1 with a receiving pipe 2 for supplying

heat carrier and injection pipe 3, Inside the housing 1 there is a rotor in the form of a hollow detachable disk 5c fixed on a solid shaft 4 with guide vanes 6 on the outer side surface divided by a partition 7 into compartments 8 and 9, filled from two flat discs 10 with profiled blades 11 between them, connected by overflow nozzles 12 and fixed directly on inlet 13 and outlet 14 inlets for condensing medium, placed concentrically along the rotor axis from the opposite side oh shaft.

The heat exchanger operates as follows.

Heating steam under pressure at the inlet fitting 13 mounted concentrically with the discharge fitting 14 enters the cavity of the compartment 9 of the rotating disk 5, while part of the steam is redistributed to the compartment 8 of the second half of the rotor through the inlet pipes 12, thereby film vapor condensation is provided simultaneously on both inner walls of the rotor. Condensate generated by centrifugal forces is dropped to the periphery of the rotor's internal cavity.

and, rotating with the rotor, falls into the curvilinear channels of the fixed partition 7 formed by the walls of the flat disks 10 and the profiled blades 11, and is discharged along the outlet nozzle 14 from the inner cavity of the rotor.

The heated coolant is supplied through the inlet nozzle 2 into the space between the housing 1 and the rotor at the same time to both disk surfaces of the rotor closer to its center of rotation. Pipe 2, in the case of operation, with viscous liquids, such as laprolones with a viscosity of 300-500 cP, is advisable to be done with a large through-hole in the receiving part. Upon contact with the heated steam by the rotor walls, the coolant is heated and, carried away by the blades 6 along the pressure channel, is brought out through the discharge nozzle 3. The rotor is rotated by means of a shaft 4 rigidly connected with it.
