Definitions
- the invention relates to a heat exchanger with numerous cooling fluids flowed through, approximately parallel to each other heat exchange tubes, which in a channel through which hot gas flows are arranged, each Heat exchange tube has several turns and in the area between the Turns is in contact with a tap tube, with jerky movements of the Knock tube generate vibrations in the heat exchange tubes.
- a heat exchanger of this type is known from DE 4121815, the tubes in the Area of adjacent turns to be hit against each other for cleaning. The detachment of deposits takes place in a very similar manner in the case of those from US-A-3997000 and DE 2809735 A known heat exchangers with vibrators.
- the invention is based on the object, deposits and caking on the Eliminate heat exchange tubes in a simple and effective manner. According to the invention, this is achieved with the heat exchanger of the type mentioned at the beginning in that each heat exchange tube is stationary in the area of all of its turns is attached. The knock tube generates vibrations of the heat exchange tubes and this will cause the toppings to come off and fall off.
- the knock pipe which vibrates in the Heat exchange tubes can be produced in various ways be trained.
- the knock pipe advantageously runs in the Area of contact with the heat exchange tubes, for example perpendicular to the heat exchange tubes. This can cause bumps intense vibrations in the knocking tube generate the heat exchange tubes.
- the knock pipe with the Heat exchange tubes is connected, but this connection is expedient to a stable arrangement even in continuous operation to have.
- the knock pipe is wound several times and designed to be elastically movable, with impacts on it Turns are transferred to the heat exchange tubes. there it is possible to only use the heat exchange tubes to initiate in sections.
- the hot gases shown in cross section in FIG gas channel (1) with an upward flow has several inside Heat exchange tubes (2).
- a single heat exchange tube (2) visible and it is in Fig. 2nd in its form with several turns (2a), (2b) and (2c) detect. They are in the area of the turns Heat exchange tubes (2) attached to supports (3), the self are connected again with vertical support tubes (4).
- Figure 1 is the connection between the supports (3) and Heat exchange tubes (2) for better clarity not shown.
- the heat exchange tubes (2) are in Connection with collecting chambers (6) and (7) for the inlet and Removal of cooling fluid, e.g. Water vapor, water, air or oil.
- a tapping tube (8) which is shown in view in Figure 3, runs perpendicular to the heat exchange tubes (2) and is included coupled this.
- the coupling exists from tabs (9) with the tapping tube (8) and a horizontal part of a heat exchange tube are welded.
- the tabs are the better ones Not shown for clarity.
- Tabs can e.g. B. sleeves can also be used.
- both the support tubes (4) and the tapping tube (8) flowed through by cooling fluid be trained.
- the tapping tube (8) has through its tortuous shape, see FIG. 3, a certain elasticity in Direction perpendicular to the heat exchange tubes (2).
- the Knock tube is connected to a plunger (10) that goes through the wall of the channel (1) is led to the outside.
- jerky Movements of the ram (10) e.g. by blows with a Hammer, be connected to the tapping tube (8)
- Heat exchange tubes (2) perpendicular to their longitudinal axis triggered and thus set in short vibrations. This Vibrations cause the deposits on the Outside of the heat exchange tubes (2).
- the knocking tube (8) from the outside can not only be mechanical but e.g. can also be done pneumatically or electromagnetically.
- the tapping tube (8a) shown schematically in Figure 4 is wound several times and has several, led to the outside Ram (10).
- the connection of this tap tube (8a) with the associated heat exchange tubes, which are analogous to FIG. 3 is left out in Figure 4.
- tapping tube (8b) shown in FIG. 5 shows the guide of the kinked in the area of the turns (18) Tapping tube (8b).
- This shape of the turns ensures that pushing a single plunger to vibrate in the Knock pipe leads that does not affect other areas of the Knock tube are transmitted. Otherwise they have Reference numerals in Figure 5 that previously explained Importance.
- the tapping of the heat exchange tubes according to the invention can for both horizontal and vertical flow Channels or boilers can be used.
