Problems solved by technology

[0006] A disadvantage of the known tube bundle arrangement is that, in particular when there is a large temperature difference between the medium in the throughflow line and the medium in the circulation line, the longitudinal expansion of the tubes and the housing differs, so that the tubes can be deformed in the tube bundle arrangement
Also, it is often not easy to replace the tubing from the bundle when needed or when cleaning the bundle or casing
[0007] To avoid this deformation, compensators are usually used on the housing side of the device, but compensators can only be used in devices with limited wall thickness in the low pressure range
The compensator is a known weak point of this construction, failure of which can result in spillage of the medium in the enclosure space into the environment

Embodiment Construction

[0032] figure 1 The tube bundle equipment is shown in section.

[0033] The tube bundle arrangement 1 comprises a housing 3 which has a housing 5 which is closed at both ends by a cover 7 . The housing 5 is generally cylindrical here, but it can also have any other cross-section besides a circular cross-section.

[0034] The top cover 7 is usually fastened to the housing 5 respectively by means of a flange connection.

[0035] A tube bundle 9 is accommodated in the housing 3 . The tube bundle 9 comprises a first tube base 11 , a second tube base 13 and pipes 15 . The pipes 15 are here fastened with their ends in one of the two pipe bases 11 , 13 . In this case, the pipes 15 are preferably fixed in the tube bases 11 , 13 in such a way that they each end flush with the tube bases 11 , 13 . This prevents liquid from standing on the tube floor and not being able to flow into the pipe 15 during the vertical operation of the tube bundle arrangement 1 .

[0036] The tube bases ...

Abstract

The invention relates to a tube bundle arrangement comprising a housing (3) and a tube bundle (9) of pipes (15) accommodated in the housing, the pipes being connected at one end to a first tube base (11), The other end opposite to the first tube bottom (11) is connected to a second tube bottom (13), wherein the first and second tube bottoms (11, 13) are fixed in the housing in a detachable manner. The first tube base (11) is supported on its side opposite to the pipe (15) and fastened to a stop (31) on the housing (3), the second tube base (13) through the sealing element (41) is guided in the housing (3). The invention also relates to the use of tube bundle devices.

Description

technical field [0001] The invention relates to a tube bundle apparatus comprising a housing having a tube bundle accommodated therein with pipes connected at one end to a first tube base and at the other end opposite to the first tube base Connected to the second tube base, wherein the first and second tube bases are detachably fixed in the housing. [0002] The invention also relates to the use of tube bundle devices. Background technique [0003] Tube-bundle devices are often used where heat transfer from a first medium to a second medium is necessary. Such devices are, for example, heat exchangers or reactors. In the tube bundle equipment, the first medium flows through the pipe, and the space around the second medium flows through the pipe. Fluid transfer can be in direct current, convective, cross direct current or cross convection. For the flow guidance of the cross direct current or cross convection mode, each pipe of the tube bundle equipment is guided by a defl...
