The invention relates to a heat exchange apparatus and can be used in the energy industry.

The aim of the invention is to intensify heat exchange by creating a forced circulation in the bulk liquid.

FIG. 1 shows schematically the described heat exchanger; in fig. 2 is a section A-A in FIG. one; in fig. 3 is a section BB in FIG. one; in fig. 4 section bb In fig.Z.

The heat exchanger contains 1 rows immersed in liquids of vertical body-exchange elements 2, united by upper 3 and lower 4 headers and equipped with axial circulation pipes 5, whose ends 6 are outside of headers 3 and 4. In fluid 1 below the lower header 4 gas distribution manifold 7 is placed, provided with vertical nozzles 8 and installed over them with the ability to move the overturned cups 9, introduced with an annular gap 10 into the corresponding circulation pipes 5. Glasses 9 sticks epleny to the rod 11 provided at the other end a plate 12 with holes 13 in a ring for the passage of gas. On the inner surface of the nozzle 8 between the cups 9, and the plates 12, stops 14 are mounted to restrict the movement of the cups 9. The plates 12 are mounted with a gap relative to the inner surface of the nozzles 8.

The heat exchanger can be made with an annular arrangement of elements 2 and annular collectors 3 and 4.

Vertical heat exchanger works as follows.

led by cooling coolant coming from the collector 3 to the annular gap between elements 2 and pipes 5. At the same time, from the collector 7 air is supplied to the pipes 8. Under the air pressure, the cup 9 rises and the air rises through the annular gap between the pipe 8 and the glass 9 a culture liquid filling the pipe 5. An air lift effect is created in each pipe 5 and the air entrained fluid rises up the pipe, respectively, a vacuum is created in the gap between the pipe and pipe 5, resulting in m suction effect and zasasyvaet- culture fluid with the pipe 5. Therefore, under the influence of the air flow coming from the reservoir 7, is created circumferential stimulated cultures tral circulation fluid. After the fermentation process is completed, the cup 9 is lowered under the force of gravity, which prevents liquid from entering the collector 7.
