Definitions
- the invention relates to a method for cleaning the slats of
- Invention also relates to a device for cleaning these surfaces.
- the aim and purpose of the invention is to provide a method and a device for cleaning fin heat exchangers, which is a gentle but effective
- Amounts of water as a blasting abrasive cleaning method is provided, which is particularly suitable for the cleaning of finned heat exchangers. Since compressed air with a low water content has a much lower density than a water jet and can be brought by a corresponding nozzle to a very high speed, a complete penetration of the heat exchanger is achieved even at low pressure of the carrier gas.
- Beam angle to the surfaces to be cleaned is close to 0 °, the jet pressure exerted on the surfaces is very low here.
- the surprising cleaning effect can not arise here from the impact of the nozzle jet on the surface, but results surprisingly from the friction effect of the nozzle jet on the surfaces of the lamellae.
- Carrier gas is fed ström and thus brought to high speed, at least approximately the speed of sound or supersonic speed.
- Experiments have shown that at relatively low pressure of the compressed air from 1 bar, preferably from 1.5 bar and thus a relatively low jet contact pressure already a complete penetration of the nozzle jet is achieved by fin heat exchanger.
- Lamella heat exchangers with larger overall depths, the jet pressure can be increased in each case as far as it allows the strength of the slats. It also removes solid or sticky dirt layers without bending or otherwise damaging the thin lamellae. To achieve a uniform cleaning with as little as possible
- Overlapping surfaces preferably a flat nozzle is used.
- the flat nozzle often has a lower cleaning effect when used in the cleaning of "normal" surfaces compared to a round nozzle, when cleaning
- finned heat exchangers reach the jet more effectively in the narrow channels of the fin heat exchangers, since the rebound effects on the front of the exchanger are greatly reduced. This leads to an improved and uniform cleaning effect.
- the throughput of the carrier gas is 4000 liters per minute, preferably 6000 liters per minute.
- the amount of water in liters should preferably be less than 1: 1000 in relation to the compressed air.
- the pressure of the water supplied should be at a distance of min. 30 mm in front of the throat of the jet nozzle amount to at least 50% of the pressure of the compressed air, but preferably be similar to or higher than the pressure of the compressed air.
- the water pressure can be dependent on the
- High-pressure cleaners even superior high cleaning effect is achieved, which can also solve solid or sticky dirt layers, without attacking the underlying surfaces or damage the slats.
- High-pressure cleaners even superior high cleaning effect is achieved, which can also solve solid or sticky dirt layers, without attacking the underlying surfaces or damage the slats.
- a pulsating beam through the impulses for cleaning success contributes to the effect of ultrapure water droplets.
- the jet can be brought by the design of the water pump and / or by corresponding valves in the water and / or compressed air supply to the pulsation, which leads to an increase in the cleaning effect.
- an existing sufficient pre-pressure of the water can also be dispensed with an additional pump to increase the pressure of the water.
- An improvement of the cleaning effect can also be achieved by heating the compressed air z. B. caused by heat exchangers to z.
- the required water preferably has drinking water quality but also properties close to drinking water quality. However, for special requirements there is also the possibility of improving the effect by changing the pH of the water.
- Laminated heat exchanger For cleaning, preferably only compressed air and water are used here.
- the device in this case comprises a jet nozzle with a feed for the compressed air, wherein the jet nozzle has a converging to a constriction portion and an adjoining diverging section.
- Supply line for the water provided to add the water before, in or after the Blasting nozzle is formed.
- the volume of water to the volume of compressed air in the ratio of less than 1: 1000, preferably less than 1: 2000.
- the jet nozzle is advantageously designed convergent-divergent, preferably as a Laval nozzle.
- a suitable throttle valve for regulating the amount of water is attached in the liquid supply upstream of the jet device.
- the water / liquid is directly or via a distribution chamber with at least one
- a diaphragm pump or a piston pump is preferably provided.
- the cubic capacity should be less than 1.00 liters.
- a pressure booster can be arranged behind the diaphragm pump.
- the promotion of the water can be made by any type of pump, preferably by a diaphragm pump or piston pump, which sucks the water, but can also accept from a water hose under pressure.
- a diaphragm pump or piston pump which sucks the water, but can also accept from a water hose under pressure.
- Power sources can be supplied.
- the pressure of the control air can be kept small, but the water pressure can be increased far above the control pressure.
- the generation of a pulsating nozzle jet can be caused by the design of the pump as a diaphragm pump and / or by the use of breaker valves for water and / or compressed air.
- the line from the water inlet to the pump can have different diameters.
- demineralization of the water takes place before introduction into the device or into a device having the device (eg osmosis system or ion exchange system).
- Figure 1 is a sectional view of a jet nozzle according to the invention in a first
- Figure 2 is a sectional view of a jet nozzle according to the invention in a
- Figure 3 is a sectional view of a jet nozzle according to the invention in a third
- Figure 4 is a sectional view of a jet nozzle according to the invention in one
- Figure 1 shows in the sectional view of a jet nozzle 1, in which serving for supplying the water line 2 into a distribution space 3 and then through the
- Outlet 4 is guided in the beam line 5, which opens into the jet nozzle 1.
- the pressurized compressed air 9 and water, or other liquid substance, the jet nozzle 1 are supplied.
- the jet nozzle 1 in this case has a converging to a constriction 6 section 7 and an adjoining diverging
- Section 8 water or other liquid substance preferably in front of the jet nozzle 1, in another embodiment before, in or after the constriction 6 of the jet nozzle 1 are metered into the compressed air flow.
- FIG. 2 shows a further example of a jet nozzle 1, in which the line 2 serving to supply the water opens directly into the jet line 5.
- FIG. 3 shows a further example of a jet nozzle 1, wherein the line 2 serving to supply the water opens into the jet nozzle 1 directly in front of the constriction 6.
- FIG. 4 shows a modified example of the flat jet nozzle 1, in which the line 2 serving to supply the water flows into a distribution space 3 and then through the
- Outlet 4 is guided in the beam line 5, which opens into the jet nozzle 1.
- a carrier gas other than air and another additive liquid other than water may be used.
