Definitions

  • the invention relates to a cleaning device for heat exchangers, in particular air conditioning systems.
  • Air condensation plants are used as a closed system for condensing the exhaust steam or the excess steam of turbine plants.
  • the total cooling surface is designed for the amount of steam produced. It is assumed that a certain heat transfer from the cooling surface into the ambient air. The heat transfer, however, does not remain constant. On the cooling surfaces it comes to the outside for pollution. Pollution is caused by, among other things, bee pollen, leaves, industrial emissions, flue dust and leads to deposits on the cooling surfaces. As a result, the heat transfer deteriorates.
  • Turbines are designed for a Abdampftik of 0.2 bar absolute, they are e.g. switched off at a rise in the vapor pressure to 0.8 bar by monitoring devices. Depending on the design of the control, other limit values result.
  • cooling surfaces are arranged in multiple layers or consist of fin coolers with very high ribs. In the case of multi-layer cooling tubes, an improper procedure or the use of unsuitable equipment only causes a loosening of dirt on the upper layer and an attachment to lower rows / layers. Cooling surfaces with high ribs are at the same risk. On the way, the cooling air can even be blocked from passing through the radiator.
  • cooling with aluminum cooling fins has been found to cause damage to the fins quite easily with high pressure equipment. Excessive pressure will bend the ribs if handled improperly. This is not immediately obvious to the operators, because the cooling surfaces are usually not regularly driven, i. to be watched. Thus, it is not possible to control when and who caused what damage and have encountered situations in which the radiator were unusable by cleaning.
  • An older proposal provides for a mobile cleaning device with a rotating spray arm which is moved along the cooling fins.
  • the spray arm is mounted centrally rotatably.
  • At each end of the spray arm is a flat jet nozzle, which is to spray the dirt from the cooling fins.
  • a reliable cleaning of the Cooling surfaces is thus not achieved, because only in a rotational position exactly transverse to the rib longitudinal direction an accurate penetration of the rays is achieved in the space between the cooling fins.
  • the jet direction becomes increasingly unfavorable to a minimum cleaning effect. Thereafter, the cleaning effect is better again, until an optimum is reached, in which the rays penetrate exactly between the cooling fins.
  • the efficiency of such devices is substantially improved by using nozzles whose position relative to the cooling fins remains essentially unchanged during the rotational movement of the spray arm. This will allow actual cleaning without the risk of damage.
  • Another prior proposal provides that a cleaning device for multiple cooling surfaces (cooling registers) of a system is used. This is achieved by means of a driving system.
  • the driving system resembles a crane track, with which the device is converted from one cooling surface to the other.
  • the stationary cleaning devices and the implementable cleaning device have in common that initially a considerable investment must be made. This naturally precludes the use of such devices.
  • two or more profiles may be arranged side by side.
  • the use of a single profile involves a special step towards an optimally lightweight and functionally reliable device.
  • the weight advantage of a single profile is not readily apparent because several juxtaposed profiles with the same cost of material computationally have a greater bending resistance than a single profile. Nevertheless, it does not come alone, on the larger moment of resistance. It comes too on the fact that the guide rollers do not cause deformation of the rolling surfaces. This leads to a minimum thickness / width of the rolling surfaces and profiles. Two minimum thickness profiles can result in more material than a single load-bearing profile.
  • the profile is designed as a hollow profile, as a square profile, and length-adjustable by connectors.
  • the extensibility facilitates working with a single device on different lugs or the like. Regardless of the profile of the extensibility and the connector are therefore also of particular importance.
  • the profile and the connector are favorable for a change in length. After the older proposal, the profile can be composed of several parts.
  • the device may also have a head and a foot and between the head and foot to a length changeable profile.
  • the plug-in connection is brought about by means of separate domes / pins, which engage in two pipe ends to be connected to each other. But it can also be dome / pin attached to the pipe ends, so that the one tube engages with a mandrel / pin in the other tube.
  • the dome / pin hollow or in turn be designed as pipes.
  • the connector may be designed to be self-clamping and / or have a different mechanical security.
  • the holders for wheels / wheels / discs can be arranged adjustable or fixed.
  • the arms and / or head and / or foot may be releasably assembled from parts so that replacement in adaptation to particular needs is possible.
  • the drive includes a power transmission means such as a belt, chain, rope or belt, in particular a toothed belt, and a geared motor with a drive pinion.
  • a power transmission means such as a belt, chain, rope or belt, in particular a toothed belt
  • the power transmission means is preferably passed over the head and foot and generates the necessary tension.
  • the associated roller / wheel / disc is adjustable transversely to the longitudinal direction of the power transmission means.
  • the power transmission means engages the carriage and is moved by means of the geared motor. In this case, the power transmission means can be guided around the drive pinion or pressed by means of another roller / wheel / disc against the drive pinion.
  • the nozzles or the spray arm despite limited width by moving or moving across the entire width / length of the trolley to clean all the underlying cooling tubes.
  • the heavy weight reduction also protects the cooling registers when the cleaning device is moved on the cooling tubes.
  • driving profiles are preferably provided on the cooling registers.
  • the weight reduction for the handling of the device is advantageous.
  • the weight reduction is especially gentle on cooling coils with sensitive cooling fins.
  • the sensitive cooling tubes / ribs include e.g. those with rectangular cross-section, between which the cooling fins are guided back and forth as a meandering metal band.
  • the low weight brings no risk of excessive load on the cooling coil with it.
  • the water supply to the cleaning device can take place via a hose line entrained.
  • the water through an intermediate pump on the desired pressure brought.
  • the pump can be attached to the device or placed separately in front of the device.
  • Venetian blinds are for example in the DE-OS2443589 described. There are fixed and movable blinds. The blinds can have different functions. You can influence the airflow passing through the cooling coils. You can also cause shading next to it. This can also serve to even out the cooling effect of the registers.
  • the invention leads back to the fact that the nozzle sticks can not be moved close enough to the cooling register because of the blinds. Depending on the structure of the blinds, additional distances of up to 600 mm and more may result.
  • the nozzle sticks include a pipe construction of distribution pipes, which preferably lie in one plane.
  • the nozzles are attached directly or by means of a nozzle connection to the tubes of the nozzle.
  • the connection may consist of a welded pipe socket or of a part which is clamped around the associated pipe.
  • pipe sockets are common as connections of the nozzles, which are welded at one end to a pipe of the nozzle block and provided at the other end with an external thread. At the threaded end of the known nozzles are screwed with a union nut. It can also pipe socket with internal thread into consideration.
  • the invention is based on the fact that with the use of flat jet nozzles whose cleaning jets with increasing distance of the nozzles from the cooling tubes according to the beam angle are becoming wider, so that an ever greater overlap of cleaning jets takes place before hitting the cooling tubes.
  • the invention has recognized that the cleaning jets disturb each other and deprive their energy.
  • the invention is therefore based on the object to improve the cleaning effect of such cooling registers. According to the invention, this is achieved by using nozzles with built-in flow straightener. Such nozzles are known per se in the descaling of steel sheets. There, the scale is cut off with high-energy water jets. For the cleaning of cooling registers such a burden would be unthinkable, because that would lead to the immediate destruction of the cooling fins on the cooling tubes. Usually, the cooling fins are in fact very easily executed. As explained above, for example, the cooling fins are made of aluminum, and the fins are immediately deformed under excessive load. This hinders the passage of the cooling air. Nevertheless, the invention has turned to the nozzles known from descaling.
  • the rectifier is a flow channel which is arranged in the longitudinal direction of the nozzle.
  • various guide devices preferably in the longitudinal direction of the flow extending webs are provided which direct the water and prevent large-volume eddies. Because of the details is on the DE29706863U1 and the DE69524045 With reference to the rectifier, the beam is more focused. The beam angle is reduced. With equal distances of the nozzles, the nozzles can then be spaced further from the cleaning surface.
  • a radiation angle of at most 26 degrees at the angularly spreading flat jets is provided.
  • rectifiers having a length of at least 30 mm, preferably of at least 50 mm and even more preferably of at least 70 mm are used.
  • the rectifier can be part of the nozzle.
  • the rectifier can also be part of the nozzle assembly. That is, a part of the nozzle can be permanently attached to the nozzle. Preferably, however, the nozzle is releasably secured. This facilitates cleaning, maintenance and repair as well as replacement.
  • the rectifier is at least partially positioned in the above-described connection and / or in the associated tube of the nozzle. It is advantageous if the associated pipe of the nozzle has at least in the region of the nozzle connection an enlarged diameter and if the rectifier can thereby penetrate further into the pipe of the nozzle block.
  • the nozzle assembly is also constructed so that a pipe end opens at each nozzle.
  • a pipe end opens at each nozzle.
  • this is achieved in that run from at least one transverse to the longitudinal direction of the cooling tube pipe several branches; namely, a tube is provided for each nozzle, wherein the tubes have at least at the tube end in the nozzle direction or in the jet direction.
  • the construction reduces the flow losses of the water in the pipes.
  • the one advantage is formed by the possibility to let the rectifiers described above protrude into the pipe ends to the pipe ends.
  • the other advantage is formed by the ability to use the pipe ends as an immediate connection for screwing the nozzles.
  • For direct connection depending on the pipe diameter, bear the pipe end with an external thread or an internal thread.
  • the external thread is very advantageous to attach the nozzles with a union nut at the pipe end or screw the then provided with an external nozzle nozzle in the female threaded end of the pipe.
  • all of the tubes belonging to a nozzle have the same diameter or different diameters. Different diameters may result, for example, in the case of the above-described increase in diameter or even if the tubes have larger diameter up to the tube ends and are reduced in diameter at the tube ends.
  • At the pipe ends or to be welded to fittings are preferably outer diameter less than 45mm, even more preferably outer diameter smaller than 35mm and optionally also outer diameter smaller 25mm provided.
  • the rectifiers in the nozzles may also have a length of at least 90mm or a length of at least 110mm.
  • All pipes are designed as high-pressure pipes, so that at a designated cleaning water pressure on the cooling pipe, a corresponding flow of water in the pipe system is possible to achieve by overcoming the distance caused by blinds still sufficient cleaning.
  • manifolds are used on the pipelines to prevent pressure loss rather than angles.
  • the water pressure is in the nozzles in conventional finned tube coolers preferably 80 to 100 bar, in sensitive cooling tubes or in cleaning-friendly cooling tubes also significantly less, for example 40 to 50 bar.
  • adjustable pumps are advantageous, the adjustment of the occurring pressure ranges at least partially, preferably completely covers.
  • the rectifier technology is also advantageous for other coolers without blinds.
  • the bundled cleaning jets from nozzles according to the invention have a greater cleaning effect than conventionally used jets.
  • the bundling also results when the rectifier is arranged in front of the outlet-side nozzle opening.
  • the pump pressures can be reduced while the cleaning effect remains the same.
  • the amount of the cleaning liquid can be reduced. Reducing pump performance is important for many installations where there is little cleaning water available and where the installed electrical power is too low for higher pumping capacities.
  • the cleaning nozzles with rectifier according to the invention also allow proper cleaning even if there are obstacles in the track of the nozzle. Then the nozzle can be raised, optionally by increasing the water pressure to lift the nozzle with the same cleaning performance on the obstacles.
