Definitions
- the invention relates to a portable cleaning device for heat exchangers, in particular air consumption systems.
- Air condensing systems are used as a closed system for condensing the exhaust steam or excess steam from turbine systems.
- the total cooling surface is designed for the amount of steam produced. A certain heat transfer from the cooling surface to the ambient air is assumed. However, the heat transfer does not remain constant. Contamination occurs on the outside of the cooling surfaces. The pollution is caused, among other things, by pollen, leaves, industrial fumes, dusts and leads to deposits on the cooling surfaces. This worsens the heat transfer.
- Turbines designed for an absolute steam pressure of 0.2 bar absolute are switched off by monitoring devices when the steam pressure rises to 0.8 bar.
- the cleaning is preferably carried out manually.
- the cleaning work is usually transferred to the cleaning columns, which are also subject to other cleaning work. There is a tendency to award this work as a complete package.
- At all cleaning companies however, only hand-held steam jet devices or high-pressure water jet devices are available. The success of working with a handheld device is low. Only the loose dirt is rinsed off.
- the cooling surfaces are arranged in multiple layers or consist of fin coolers with very high fins. In the case of multi-layer cooling pipes, improper handling or the use of unsuitable equipment will only loosen dirt on the upper layer and cause deposits on the lower rows / layers. The same risk exists for cooling surfaces with high fins. On the way, the cooling air can even be blocked from entering the cooler.
- An older proposal provides for stationary cleaning devices with which a reliable cleaning of the cooling surfaces is achieved. With such cleaning devices, the cleaning nozzles, their position and the cleaning pressure can be adapted to the cooling surfaces. This enables actual cleaning without the risk of damage.
- Another older proposal provides that a cleaning device is used for several cooling surfaces (cooling register) of a system. This is achieved with the help of a driving system. The driving system resembles a crane runway with which the device is moved from one cooling surface to another.
- the above problems are countered by a) creating a portable cleaning device with a trolley, b) overlapping a plurality of cooling pipes or also a plurality of cooling registers and c) the cleaning device has a supporting structure with an edge profile running in the direction of travel of the trolley and the carriage is arranged to be movable on the edge profile and / or the supporting structure can be changed in length by means of plug connections
- Two or more edge profiles can also be arranged side by side.
- the use of a single edge profile involves a special step towards an optimally light and at the same time functionally reliable device.
- the weight advantage of a single edge profile is not readily recognizable, because several edge profiles arranged side by side have a greater bending resistance than a single edge profile with the same amount of material. Nevertheless, it is not only the greater moment of resistance that is important. It is also important that the guide rollers do not cause any deformation of the rolling surfaces. This leads to a minimum thickness of the rolling surfaces and edge profiles. Two at least thick edge profiles can result in a greater expenditure of material than a single load-bearing edge profile.
- the edge profile is preferably designed as a hollow profile and can be changed in length by plug connections.
- the changeability in length facilitates working with a single device on different hatches or the like. Regardless of the edge profile, the changeability in length and the plug connection are therefore of particular importance.
- the edge profile and the plug connection are favorable for a change in length. According to the older proposal, the edge profile can be composed of several parts.
- the device can also have a head and a foot and between the head and the foot an exchangeable edge profile for changing the length.
- the plug connection is made with the help of separate mandrels / pegs which engage in two pipe ends to be connected. But there can also be spikes / pins on the
- Pipe ends are attached so that one pipe with a mandrel / tenon in the other
- mandrels / pins can be hollow or in turn can be designed as tubes.
- the plug connection can be designed to be self-locking and / or a mechanical one
- arms for different purposes are located on the head and foot of the device, e.g. for supporting and / or guiding and / or holding the
- Holder for drives and / or pumps may be provided.
- the brackets for rollers / wheels / discs can be adjusted or fixed.
- the arms and / or head and / or foot can be detachably composed of parts so that they can be replaced to suit specific needs.
- a plug connection as with the edge profile can be favorable. This is beneficial if arms, head and foot are composed of the same profiles.
- the drive preferably 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
- a geared motor with a drive pinion.
- the power transmission means is preferably guided over the head and foot and the necessary tension is generated.
- the associated roller / wheel / disc can be adjusted transversely to the longitudinal direction of the force transmission means to generate tension.
- the power transmission means engages the trolley and is moved by means of the gear motor.
- the power transmission means can be guided around the drive pinion or pressed against the drive pinion by means of a further roller / wheel / disc.
- the use of aluminum for the profiles and a limited width of the nozzles or the nozzle assembly in the carriage help to reduce weight.
- the limitation is given by the number of nozzles arranged on a tube in the nozzle assembly.
- the nozzles or the nozzle assembly can clean all cooling tubes underneath by moving the entire width / length of the vehicle.
- the strong weight reduction also protects the cooling register. This is particularly important for cooling registers with sensitive cooling fins.
- the sensitive cooling tubes / fins include e.g. those with a rectangular cross-section, between which the cooling fins are guided back and forth as a meandering metal strip.
- the low weight poses no risk of excessive loading of the cooling register.
- the water supply to the cleaning device can take place via a hose line carried along.
- the water is brought to the desired pressure via an intermediate pump.
- the pump can be attached to the device or placed separately in front of the device.
