Description

one

The invention is attributed to heat exchangers and can be used, in particular, in alumina production to increase the degree of heat recovery of pulp in a1 cell batteries.

Known to: pipe heat exchangers with heat exchange elements such as a pipe in a pipe, the inner ones of which are connected one end of M to the distributing collector are made longer than the outer ones and are placed in the holes of the pipe D01sok, which form overflow chambers for the ring with difficult rasches of the outer pipes; space.

Odiako in heat exchangers and it is possible to provide similar speeds in the annular annular and tubular npocTpaiHCTvah with the same flow rate of liquid. The cleaning of the intermittent and circular ring prostate of such a device with the flow of visually viscous unwotted wounds, which have a high crunching ability at very high temperatures, is very difficult.

The aim of the invention is to simplify the operation of the apparatus when it is used in gliozemic production.

This is achieved by the fact that the other ends of the B pipes are placed in the holes of the tube plate with a gap and are connected to the overflow manifold attached to this board using a detachable connector m.

On fng. Figure 1 shows a second shell-and-tube heat exchanger, section; in fig. 2 is the same; the section along A-A and B-B in FIG. one.

Teploob: mennik contains casing 1, heat-insulated tube type in t | rube elements 2, tube plates 3, 4, tube racks 5, 6, dispensing manifold 7 tube propellant environments, overflow chambers C and D of annular space environment, flow-through collector 8 collecting collector 9, fitting 10 and for supplying a heated medium, fitting 11 for withdrawing it, fitting 12 for supplying a heating medium and fitting 13 for withdrawing, partition 14 separating collectors 7 and 9 and allowing

to provide multi-way movement of media both through internal pipes and annular space.

Heated medium with a great incrustation power is supplied through shtutser 12

into the distributing collector 7 and enters the inner tubes of the heat exchange elements 2 nepiBoro strokes. The flow through the pipe bundle of the first turn and through the overflow collector 8, the heated medium enters the next beam

in the course of the movement. Passing a predetermined number of strokes, which varies depending on the number and location of the partitions in the dispensing manifold 7, the collecting manifold 9 and the overflow manifold 8, the heated medium is discharged through the switch 11.

G | reyup1, and the environment is fed into the overflow channel
