Definitions

  • the present invention relates to a method and a device for removing deposits, preferably metal oxide (e.g. rust) or lime deposits in a pipeline system, in particular a water pipeline system.
  • deposits preferably metal oxide (e.g. rust) or lime deposits in a pipeline system, in particular a water pipeline system.
  • the object of the present invention is to provide a method and a device of the type described at the outset which have an improved effectiveness in comparison with the known solutions.
  • ultrasonic vibration energy is emitted into the pipeline system by means of an ultrasound source arranged within a pipeline system and surrounded by water. It has surprisingly been found that ultrasonic waves have a very strong cleaning function on the interior of the piping system, the liquid medium present in the piping system, e.g. Water, the cleaning medium. Water, in particular, is particularly suitable for transmitting ultrasonic vibrations, so that the cleaning ultrasonic waves spread widely in the pipeline system and their effect is felt even in the most remote areas.
  • the vibration energy of the ultrasound source is radiated in the longitudinal direction of the piping system, preferably in the water flow direction.
  • a piezoelectric sound generator can advantageously be used as the ultrasound source, which has the advantage has that it can be manufactured in any shape.
  • the oscillation frequency and / or oscillation energy of the emitted ultrasonic oscillation in view of the data given by the installer, namely details of the type of deposits (red-brown for rust or white for limescale deposits) the oscillation frequency and / or oscillation energy is set accordingly can be.
  • the method can consequently be operated by the user with different vibration frequencies and / or vibration energies. The selection of the respective company can be done with a simple switch.
  • the temperature at the respective ultrasound source is expediently monitored. For example, at a measured temperature of more than 35 ° C, the operation of the method can be automatically stopped by emitting an appropriate signal. If the water in the piping system flows around the respective ultrasound source, there is no risk of overheating. However, as soon as the water in the area of the ultrasound source is left for a long time, such heating and sometimes overheating is possible.
  • the respective emission of ultrasonic vibrations in the pipeline system in certain time periods, ie intermittently. For example, this can be done in minute or even hourly intervals.
  • the emission of ultrasonic vibrations with alternating vibration frequencies can expediently take place with the aim of exposing the deposits to one (of several possible) vibration frequencies that is particularly effective.
  • the device according to the invention is characterized in that at least one ultrasound source is provided in a housing and the housing can be integrated into the piping system, so that the ultrasound source is able to deliver its vibrational energy to the water in the piping system.
  • the ultrasound source is expediently located in a resonator, which emits the vibrations generated by the ultrasound source, the resonator being in water contact and from a two-part housing is surrounded, which can be connected to the piping system.
  • the resonator In order to ensure effective transmission of the ultrasonic vibrations, the resonator consists of solid material, the ultrasonic source being arranged in a recess of the resonator and the recess being closed by a cover.
  • the main direction of vibration of the ultrasound source can be influenced by the shape (e.g. plate or disk shape) and arrangement of the ultrasound source within the resonator. If a disk-shaped ultrasound source is arranged perpendicular to the longitudinal axis of the piping system, the ultrasound vibrations are also emitted in the longitudinal direction of the piping system.
  • the resonator is provided with support projections which engage on the inside of the housing and there is otherwise a circumferential gap between the housing and the resonator, which ensures that the resonator is completely surrounded by water except for the surface of the support projections.
  • the resonator is thus only connected to the housing via its support projections.
  • the support projections are preferably made of flexible material (for example made of flexible plastic or rubber) in order to avoid unpleasant vibration noises being generated in the piping system, in particular when using a low-frequency fundamental vibration.
  • the housing can have an annular recess, in which an ultrasound source designed in the form of a ring or semi-ring is arranged, which at least partially surrounds the resonator.
  • the ultrasound source emits its vibration energy directly to the housing of the cleaning device and thus to the pipeline system that is firmly connected to the latter.
  • the piping system itself is consequently set in vibration, which, as already mentioned, can further increase the cleaning effect.
  • this embodiment it is therefore possible with this embodiment to at least temporarily set the pipeline system in vibration and thereby intensify the cleaning effect.
  • the ring-shaped or semi-ring-shaped ultrasound source is arranged directly on the outside of the pipe wall of the pipe system in order to achieve the same purpose.
  • Reference number 1 stands for the entire device according to the invention, which is installed in a water pipe 2 of a pipe system.
  • the device 1 comprises a housing 3 consisting of two half-shells with a centrally arranged longitudinal recess 8 and an annular recess 15 arranged concentrically around it.
  • the two half-shells of the housing 3 are connected to one another using a screw connection 26 and circumferential seals 18 and 28.
  • the respective water pipe 2 opens into an inlet opening 4 or outlet opening 5, the connection of the water pipe 2 with the inlet or outlet opening being effected via a conventional screw closure 6 or 7, which is only indicated in the drawing.
  • a resonator 9 which contains the ultrasound source.
  • the resonator 9 comprises a resonator body 10 which is made of solid material e.g. Aluminum, brass, copper or stainless steel and has a recess 24 on the downstream end, in which an ultrasound source in the form of a piezoelectric disk 14 is arranged.
  • a resonator body 10 which is made of solid material e.g. Aluminum, brass, copper or stainless steel and has a recess 24 on the downstream end, in which an ultrasound source in the form of a piezoelectric disk 14 is arranged.
  • the recess 24 is closed by the resonator cover 11.
  • the resonator 9 has on its end faces made of flexible material support projections 22 which engage in corresponding recesses 25 on the respective end face of the longitudinal recess 8.
  • a circumferential gap 23 is provided between the inside of the longitudinal recess 8 and the resonator 9, which is enlarged in the area of the incision 12 (upstream) or the incision 13 located downstream.
  • the piezoelectric disk 14 is arranged within the device 1 such that its normal runs parallel to the flow direction of the water in the pipeline system, so that the main direction of the ultrasonic oscillation of the piezoelectric disk 14 takes place in the longitudinal direction of the pipeline system.
  • the ultrasonic waves are accordingly emitted from the piezoelectric disk 14 via the resonator 9 to the water present in the incisions 12 and 13, respectively, into the piping system.
  • a contact plate 30, 31 with connecting lines is provided on the main surfaces of the piezoelectric disk 14.
  • a further ultrasound source in the form of a piezoelectric half ring or half jacket is provided within the annular recess 15, which preferably emits its vibrational energy perpendicular to the longitudinal axis of the piping system.
  • a temperature sensor 19 for example in the form of a thermocouple, is provided directly on the piezoelectric disk 14 in the recess 24 on the resonator 9.
  • the temperature sensor 19 is connected to a controller (not shown) and, when a limit temperature (for example 35 ° C.) is exceeded, causes the operation of the device 1 according to the invention to be switched off automatically
  • a feedthrough 21 is provided in the resonator 9, which, with the interposition of a seal 27 in the region of the gap 23, in a housing bushing passes in the form of a bore 20.
  • a suitable connection 29 is provided on the outside in order to be able to connect the connecting lines to the relevant components.
  • a control not shown, is provided which ensures the setting of the oscillation frequency and / or oscillation energy of the respective ultrasound sources.
  • the ultrasonic vibration to be applied to the pipeline system comprises a fundamental vibration of, for example, 25 Hz with a harmonic of, for example, 45 kHz.
  • This ultrasonic vibration can be intermittent depending on the requirements, i.e. be applied to the piping system at certain intervals.
  • ultrasonic vibration energy with an alternating vibration frequency and / or vibration energy can act on the pipeline system. This can be easily ensured by electronic means.
  • an ultrasound source 16 ′ can be provided instead of the ultrasound source 16 provided in the annular recess 15, which emits its vibrational energy via the housing 3 to the piping system 2, which directly on the outer wall of the piping system or water pipe 2 is arranged and serves the same purpose.
