Definitions

  • the invention relates to a method for cleaning the lamellae of lamellar heat exchangers, with the features of the preamble of claim 1
  • a cleaning system for lamellar heat exchangers is, for example, from WO 2010/133932 A1 known.
  • Chemical cleaning agents are also used for cleaning, which then have to be removed again with a water jet, whereby larger amounts of wastewater contaminated with chemicals arise.
  • This wastewater has to be collected on the earth's surface - if at all possible.
  • the area around the lamellar heat exchanger must be protected in order to prevent damage to the environment.
  • the aim and purpose of the invention is to provide a method for cleaning lamellar heat exchangers which has a gentle but effective cleaning effect with little use of water and the avoidance of chemicals.
  • a cleaning process is provided by means of a low-pressure cleaning process using compressed air and small amounts of water as the blasting agent, which is particularly suitable for cleaning lamellar heat exchangers. Since compressed air with a low water content has a much lower density than a water jet and can also be brought to a very high speed through a corresponding nozzle, complete penetration of the heat exchanger is achieved even at low pressure of the carrier gas.
  • the use of a low jet pressure which is only generated by means of compressed air and a small amount of pure water without additives, enables gentle but effective cleaning of the lamellas in the entire depth of the exchanger.
  • the lamellar surfaces to be cleaned are aligned parallel to the nozzle jet. Since, in contrast to the use of the method for other surfaces, such as B. graphite or foils, the jet angle on the surfaces to be cleaned is close to 0 °, the jet pressure exerted on the surfaces is very low here.
  • the surprising cleaning effect here cannot result from the impact of the nozzle jet on the surface, but rather results surprisingly from the frictional effect of the nozzle jet on the surfaces of the lamellas.
  • the problem is solved according to the invention in that compressed air is fed to a jet nozzle which has a section converging to a constriction and an adjoining diverging section, and the water is preferably fed into the carrier gas flow upstream of the constriction, possibly in or downstream of the constriction of the jet nozzle fed in and thus brought to high speed, at least approximately the speed of sound or to supersonic speed.
  • Tests have shown that at a relatively low pressure of the compressed air from 1 bar, preferably from 1.5 bar and thus a relatively low jet contact pressure, a complete penetration of the nozzle jet by the lamellar heat exchanger is achieved.
  • the jet pressure can be increased as much as the strength of the lamellas allows. This also removes solid or sticky layers of dirt without bending or otherwise damaging the thin lamellae.
  • a flat nozzle is preferably used to achieve uniform cleaning with as few overlapping areas as possible. The flat nozzle is used for cleaning "Normal" surfaces often have a lower cleaning effect than a round nozzle, but when cleaning lamellar heat exchangers, the nozzle jet gets into the narrow channels of the lamellar heat exchanger more effectively, as the rebound effects on the front of the exchanger are greatly reduced. This leads to an improved and even cleaning effect.
  • the throughput of the carrier gas is 4000 liters per minute, preferably 6000 liters per minute.
  • the amount of water supplied in liters in relation to the compressed air should preferably be less than 1: 1000 a distance of at least 30 mm in front of the constriction of the jet nozzle be at least 50% of the pressure of the compressed air, but preferably be similar to or higher than the pressure of the compressed air. If the supplied water is metered in at a distance of less than 30 mm from the nozzle constriction or in or downstream of the nozzle constriction, the water pressure can be reduced or added without pressure depending on the pressure of the compressed air, which decreases due to the increase in speed. The water is then sucked in by the high flow speed of the water.
  • the nozzle jet can be made to pulsate through the design of the water pump and / or through corresponding valves in the water and / or compressed air supply, which leads to an intensification of the cleaning effect. If there is sufficient pre-pressure of the water, an additional pump to increase the pressure of the water can be dispensed with. An improvement in the cleaning effect can also be achieved by heating the compressed air e.g. B. are caused by means of heat exchangers to z. B. to be able to clean heavily oil-contaminated surfaces faster and more successfully.
  • the required water preferably has drinking water quality, but also properties close to drinking water quality.
  • a device for carrying out the cleaning of fins of a lamellar heat exchanger is provided for the method. Only compressed air and water are preferably used for cleaning.
  • the device here comprises a jet nozzle with a feed for the compressed air, the jet nozzle having a section that converges to a constriction and a section that adjoins it.
  • a supply line for the water is also provided, which is used to add the water before, in or after the Jet nozzle is formed.
  • the ratio of the volume of the amount of water to the volume of the amount of compressed air is less than 1: 1000, preferably less than 1: 2000.
  • the jet nozzle is designed to be convergent-divergent, preferably as a Laval nozzle.
  • a suitable throttle valve for regulating the amount of water is fitted in the liquid supply upstream of the jet device.
  • the water / liquid is fed to the carrier gas directly or via a distribution chamber with at least one outlet opening.
  • a membrane pump or a piston pump is preferably provided for conveying the water / the liquid.
  • the displacement should be less than 1.00 liters.
  • a pressure booster can be arranged behind the diaphragm pump. Interrupter valves for water and / or compressed air can be provided in order to generate a pulsating nozzle jet; additional changing line diameters from the water inlet to the pump can also bring about desired voltage changes in the water.
  • the water can be conveyed by any type of pump, preferably a diaphragm pump or piston pump, which draws in the water, but can also accept it from a water hose under pressure.
  • a water pump operated by compressed air is that no additional power supply is required, with hour meters, etc. being able to be supplied by a miniature battery or other external power sources.
  • a pressure booster is installed behind the diaphragm pump or piston pump, the pressure of the control air can be kept low, although the water pressure can be increased well above the control pressure.
  • the generation of a pulsating jet can be caused by the design of the pump as a diaphragm pump and / or by the use of interrupter valves for water and / or compressed air.
  • the line from the water inlet to the pump can have different diameters.
  • a flat nozzle is used for the device particularly advantageous.
  • the use of a lance with an adjustable jet angle is particularly advantageous for cleaning hard-to-reach areas.
  • Figure 1 shows a sectional view of a jet nozzle 1 in which the line 2 serving to supply the water is led into a distribution space 3 and then through the outlet openings 4 into the jet line 5 which opens into the jet nozzle 1.
  • the pressurized compressed air 9 and water are fed to the jet nozzle 1.
  • the jet nozzle 1 here has a section 7 converging to a constriction 6 and an adjoining diverging section 8 Compressed air flow are metered.
  • Figure 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.
  • Figure 3 shows a further example of a jet nozzle 1, the line 2 serving to supply the water opening into the jet nozzle 1 directly in front of the constriction 6.
  • Figure 4 shows a modified example of the flat jet nozzle 1, in which the line 2 used to supply the water is led into a distribution space 3 and then through the outlet openings 4 into the jet line 5 which opens into the jet nozzle 1.
