Description

12..9291

FIELD: heat exchanger.

This equipment can also be used in the chemical and related industries.

The purpose of the invention is to intensify heat transfer.

Figure 1 shows the vertical film heat exchanger, longitudinal section; figure 2 is the same, top view; on fig.Z - section aa in figure 2.

The vertical film heat exchanger comprises a housing 1 with a tube bundle 2 and a collector chamber 3 mounted above it with a perforated distribution grid 4, provided on the bottom surface with vertical guides made in the form of concentric shells 5-7. Perforations in the lattice 4 are made in the form of stepped sectors with the formation of petals of 8–10 segmental shapes, bounded on the upper surface of the lattice by radial collars 11.

The pipe medium containing solids enters tangentially into

the collector chamber 3 enters the distribution grid 4. Due to the 4 perforations in the form of stepped sectors in the lattice, the pipe medium flows from the partition 4 along the lobes 8-10 at different distances from the center of the tube bundle 2, and the number of sector perforations having the same radius , proportional to the number of tubes and eubic bundle 2, which are under each perforation. From the partition 4, the liquid enters the directional concentric shells 5-7, spreads along them. and fed to the pipes.

When a distribution grid is used, the distribution of the liquid is improved, the deposition of solid inclusions in the heat exchanger is eliminated.
