BenævnelseDenominations

Mobilt rørtørringsanlæg Frembringelsens anvendelsesområdeMobile pipe drying plant The scope of production

Anlægget anvendes til den indvendige udtørring af hovedsagligt gas-, kemikalie- og olierørledninger, men også til tørring af tanke og beholdere.The plant is used for the internal drying of mainly gas, chemical and oil pipelines, but also for drying tanks and containers.

Det er mobilt på den måde, at det er installeret i en container, som kan flyttes rundt ved hjælp af en lastbil.It is mobile in that it is installed in a container that can be moved around by a truck.

Kendt teknikPrior art

Udtørring af en rørledning foregår i princippet ved at blæse tørret luft igennem rørledningen.Drying of a pipeline is in principle carried out by blowing dried air through the pipeline.

Den tørre luft er frembragt ved at føre atmosfærisk luft igennem først fordamperen (1) på et køleanlæg, hvor luften bliver kølet og den første vandudskilning finder sted. Herefter føres luften igennem en affugter (4), der bla. består af en rotor fremstillet af et stærkt fugtabsorberende materiale, hvor den endelige udtørring og dermed nedbringelsen af luftens dugpunkt til det nødvendige i pkt. D finder sted.The dry air is generated by passing atmospheric air through the first evaporator (1) on a cooling system where the air is cooled and the first water separation takes place. The air is then passed through a dehumidifier (4) which, among other things. consists of a rotor made of a strong moisture-absorbing material, where the final drying out and thus the reduction of the dew point of the air to the required in par. D takes place.

Luften trækkes igennem anlægget ved hjælp af en blæser (5), der også trykker luften op på det tryk, der er nødvendigt for den pågældende rørledning.The air is drawn through the system by means of a fan (5), which also pressures the air up to the pressure required for the relevant pipeline.

Anlægget er installeret i 2 eller flere containere sammen med en generator, der forsyner anlægget med den nødvendige elektriske energi.The system is installed in 2 or more containers together with a generator that supplies the system with the necessary electrical energy.

Amerikansk patent US 3,864,102 angår et mobilt system til tørring af rørledninger, og af den art der omfatter en kompressor til at tilføre komprimeret luft fra omgivelserne, en varmeveksler og affugtere.US Patent US 3,864,102 relates to a mobile pipeline drying system, and of the kind comprising a compressor for supplying compressed air from the surroundings, a heat exchanger and dehumidifiers.

Det tekniske problemThe technical problem

De kendte systemer har et begrænset anvendelsesområde pga. begrænsede muligheder for kapacitetsregulering af både blæser samt køleanlæg. Det er afgørende for affugterens effektivitet, at temperaturen på indblæsningsluften på affugteren er stabil og tilstrækkeligt lav.The known systems have a limited scope due to limited possibilities for capacity control of both the fan and the cooling system. It is crucial for the efficiency of the dehumidifier that the temperature of the supply air of the dehumidifier is stable and sufficiently low.

Hvis ikke den aktuelle køleydelse på køleanlægget er tilpasset luftmængden igennem anlægget er det meget vanskeligt at holde en konstant og tilstrækkelig lav lufttemperatur på indblæsningsluften til affugteren uden at fordamperen blokker op med is.Unless the actual cooling performance of the cooling system is adjusted to the air flow through the system, it is very difficult to maintain a constant and sufficiently low air temperature on the supply air to the dehumidifier without the evaporator blocking up with ice.

Det har med frembringelsen været et ønske at konstruere et rørtørringsanlæg med et meget stort anvendelsesområde med hensyn til luftmængden og dermed få muligheden for at kunne anvende anlægget til store såvel som små rørledninger og installationer, uden at gå på kompromis med affugterens 3 DK 2006 00246 Y6 effektivitet. Det er helt afgørende for affugterens funktion og dermed luftens dugpunkt i pkt. D, at temperaturen på luften i pkt. B er stabil og tilstrækkelig lav.With the creation, it has been a desire to design a pipe drying plant with a very large scope in terms of air volume and thus have the opportunity to use the system for large as well as small pipelines and installations, without compromising the dehumidifier's 3 DK 2006 00246 Y6 efficiency. It is absolutely crucial to the dehumidifier's function and thus the dew point of the air in section. D, that the temperature of the air in cl. B is stable and sufficiently low.

Det har desuden været et ønske at konstruere anlægget så kompakt, at én container var tilstrækkelig til hele anlægget inklusiv generator.In addition, it has been a desire to design the plant so compactly that one container was sufficient for the entire plant including generator.

Tidligere anlæg med samme kapacitet soro frembringelsens kapacitet ville kræve to containere, som ved rørtørringsarbejde skulle kobles sammen med luftslanger og elkabler.Previous plants with the same capacity soro production capacity would require two containers, which in connection with pipe drying work had to be connected to air hoses and power cables.

Den nve teknikThe nve technique

Det nye ved frembringelsen er, at der er anvendt frekvensomformere til regulering af luftmængden og til regulering af kompressorydelsen.What is new about the generation is that frequency inverters have been used to control the airflow and to regulate the compressor performance.

Der er ved frembringelsen konstrueret et komplet anlæg i én container, der i dette tilfælde trinløst kan variere den leverede luftmængde fra 2000 mVtime til 6000 m3/time samtidig med at kravet til en stabil og tilstrækkelig lav temperatur i pkt. B tilgodeses under alle forhold, hvilket sikrer det krævede dugpunkt i pkt. dIn the production, a complete system is constructed in one container, which in this case can infinitely vary the delivered air flow from 2000 mVh to 6000 m3 / h while at the same time the requirement for a stable and sufficiently low temperature in par. B is met in all conditions, which ensures the required dew point in section. d

Den tekniske virkningThe technical impact

Den luft, der skal anvendes til udtørringen af rørledningen tages direkte fra omgivelserne og tilgår anlægget i pkt. A. Fra pkt. A til b nedkøles luften ved hjælp af fordamperen (1).The air to be used for desiccation of the pipeline is taken directly from the surroundings and is supplied to the plant in item. A. From paragraph. A to b the air is cooled by means of the evaporator (1).

Overfladetemperaturen på fordamperen skal ligge på cirka -2,0eC. Luften nedkøles fra den omgivende temperatur til cirka +2,0°C. Fra pkt. B tilgår luften affugteren (4), hvor den endelige affugtning finder sted ved hjælp af et fugtabsorberende stof. Fra pkt- C strømmer luften til DK 2006 00246 Y6 Λ indsugningen på blæseren (6) og trykkes her videre til pkt. □, hvorfra luften tilgår den rørledning, der skal tørres. Luftmængden afhænger af rørledningens dimension og kan justeres meget nøjagtigt med blæserens frekvensomformer.The surface temperature of the evaporator should be around -2.0 ° C. The air is cooled from the ambient temperature to about + 2.0 ° C. From point. B enters the air dehumidifier (4), where the final dehumidification takes place by means of a moisture-absorbing substance. From point-C the air flows to the DK 2006 00246 Y6 Λ suction on the fan (6) and is then pushed on to point. □ from which the air enters the pipeline to be dried. The amount of air depends on the dimension of the pipeline and can be adjusted very precisely with the fan frequency converter.

ved en reduktion af luftmængden reduceres belastningen på køleanlægget dog også- Ved uændret omdrejningshastighed ville overfladetemperaturen på fordamperen {l) falde hvilket kan føre til en opblokning af fordamperen med is.however, by reducing the amount of air, the load on the refrigeration system is also reduced.

Ved en forøgelse af luftmængden forøges belastningen på køleanlægget. ved uændret omdrejningshastighed ville overfladetemperaturen på fordamperen (1) stige hvilket ville reducere affugterens (4) effektivitet.By increasing the amount of air, the load on the cooling system increases. at unchanged speed the surface temperature of the evaporator (1) would increase which would reduce the efficiency of the dehumidifier (4).

Ved hjælp af kølekompressorens (3) frekvensomformer tilpasses køleydelsen og dermed overfladetemperaturen på fordamperen dog konstant til den aktuelle luftmængde, og dermed forhindres driftsstop pga. opblokning med is. Desuden sikres fuld effektivitet på affugteren.However, with the help of the refrigeration compressor (3) frequency converter, the cooling performance and thus the surface temperature of the evaporator are constantly adjusted to the current air volume, thus preventing shutdowns due to ice blockage. Furthermore, full efficiency on the dehumidifier is ensured.

Fordampningstemperaturen holdes på -1,0 til -2,0°C. Fordampningstemperaturen reguleres af frekvensomformeren (2), der konstant tilpasser kølekompressorens (3) omdrejningshastighed til den aktuelle belastning på fordamperen. Belastningen afhænger af den aktuelle luftmængde samt den aktuelle temperatur og relative fugtighed på den atmosfæriske luft i pkt. a.The evaporation temperature is maintained at -1.0 to -2.0 ° C. The evaporation temperature is controlled by the frequency converter (2), which constantly adjusts the speed of the cooling compressor (3) to the current load on the evaporator.

Opvarmet regenereringsluft sendes af en anden intern blæser igennem en del af den konstant roterende rotor, hvorved rotoren regenereres.The dehumidifier consists of a process air blower which sends the air from section. b through a rotor inside the dehumidifier made of a strong moisture absorbing material, internally within the dehumidifier there is also a system for regenerating the rotor. Heated regeneration air is sent by another internal blower through a portion of the constantly rotating rotor, thereby regenerating the rotor.

Luftmængden afhænger også af dimensionerne på den pågældende rørledning. Ved hjælp af frekvensomformeren (5) tilpasses blæserens omdrejningshastighed nøjagtigt til den aktuelle rørledning.The amount of air also depends on the dimensions of the particular pipeline.
