Abstract

Heat exchange counter-flow tube apparatus with expansion element serves for counter-flow heat exchange of media flowing in the tube bundle and in the apparatus shell. The expansion element consists of a pipe bellows compensator fitted between the floating head cover of the tube bundle and the coupling ring of the outlet nozzle attached to the shell chamber. The advantage of the structural arrangement of the expansion element is that the expansion displacement of the tube bundle relative to the shells is not transmitted to the outlet nozzle, which is firmly connected to the shell through the coupling ring.

Description

(54) Counter-current counter-current pipe apparatus

The heat exchange countercurrent tube apparatus with expansion element serves for countercurrent heat exchange of the media flowing in the tube bundle and in the housing of the apparatus. The expansion element consists of a piping bellows compensator fitted between the lid of the floating head of the tube bundle and the coupling ring of the outlet throat attached to the housing chamber. An advantage of the construction of the dilatation element is that the dilatation displacement of the tube bundle relative to the sheaths is not transmitted to the outlet throat, which is rigidly connected to the sheath via the coupling ring.

The invention relates to a heat exchange countercurrent tube apparatus. having a tubular bundle with a floating head, in which an expansion element is provided for an outlet throat between the floating head and the chamber of the housing of the apparatus.

Until now, in countercurrent heat exchange apparatuses with floating head tube bundles, a sliding seal on the outlet throat has been used, or a bellows compensator mounted between the outlet throat and the chamber of the housing of the apparatus under stress on internal pressure has been used. A disadvantage of these solutions is that the dilatation displacement is transmitted to the outlet throat and as a result the free expansion of the outlet throat connection pipe must be ensured. In the case of a sliding seal, the seal is blackened during operation and thus leakage is lost.

The principle of the heat exchange countercurrent tubular apparatus with an expansion element according to the invention is as follows a technical solution. The tubular bellows compensator is fixed or disassembled to the floating head and directly connected to an outlet throat provided with a rigid coupling ring, which is fastened via a seal to the support flange of the adapter by screws through a split press ring, the adapter being rigidly or dismountably connected to the chamber.

In a heat exchange countercurrent tubular apparatus with an expansion element according to the invention, an expansion displacement is provided in the interior of the apparatus by designing a compensator between the floating head cap and the outlet throat coupling ring that is connected to the housing flange support flange. Another advantage is the lower constructional, technological and assembly demands of the construction compared to the previously used dilatation elements.

The heat exchange countercurrent tube apparatus with an expansion element according to the invention is schematically shown in the drawing, where in FIG. 1 is a section of a floating head apparatus with a dilatation element in a longitudinal section.

The heat exchange countercurrent tube apparatus with the expansion element in FIG. 1 consists of a housing 12, an inlet chamber (not shown) and a chamber 11 to which a tubular extension 8 with a supporting flange 7 is welded. The housing 12 houses a tubular bundle 13 with a floating head 3. The bellows compensator 1 is screwed over two connecting flanges 14 and a spacer ring 15 for the lid 2 of the floating head 3 and is directly connected to the outlet throat 4 provided with a fixed coupling ring 5, which is fastened through the seal 6 to the support flange 7 by screws 9 through a split pinch ring 10. differences in the replacement of the tube bundle 13 with a new spare part The medium in the jacket 12 circulates through the septum system of the tube bundle 13 upstream of the medium passing through the tube bundle 13 and the outlet neck 4 with the neck flange 17.
