Definitions

  • the present invention relates to a device and method for drying a compressed gas, and more particularly to a device and method for drying a compressed gas from a compressor.
  • Compressed gas for example air
  • originating from the compressor usually has a high moisture content. This moisture can be detrimental to the line network and is undesirable in certain applications. Therefore, as is known, there is a need for a device for drying a compressed gas.
  • BE1010132A3 a method and device for drying a gas, compressed by a compressor, is disclosed.
  • compressed gas is dried by passing it through a drying agent, while at the same time already used drying agent is regenerated by passing through it a portion of the compressed gas supplied by the compressor.
  • BE1027364A1 a similar method and device is disclosed, in which a heating means and venturi ejector are provided to exchange heat between the regeneration gas and the incoming compressed gas from the compressor to shorten the time of regeneration.
  • a device according to claim 1 , the device consisting of a supply, suitable for supplying the wet compressed gas, and a first and a second adsorption dryer, suitable to be filled with a drying agent, and a cooler and a water separator, a drain, suitable for discharging dried compressed gas, a set of lines and valves, wherein the set of lines and valves is configured to successively pass the wet compressed gas, in a first and second regeneration phase, respectively, from the supply to the first and second adsorption dryer, respectively, the cooler and the water separator, the second and first adsorption dryer, respectively, and the drain; and further configured to successively pass the wet compressed gas, in a first and second drying phase, respectively, from the supply to the cooler and the water separator, the second and first adsorption dryer, respectively, and the drain, CHARACTERISED IN THAT the device further comprises a ejector
  • the device comprises means as known in the state of the art, such as two adsorption dryers, a supply and a drain, and a cooling installation comprising a cooler and a water separator. Furthermore, the device comprises a set of lines and valves which connect the various means or components with each other, and which can have different functions performed by the position of the valves, also referred to hereinafter as ventils. As a result, the device can be used for conducting both regeneration phases and drying phases.
  • a regeneration phase as known in the state of the art, hot and wet compressed gas, directly originating from a compressor, is passed through an adsorption dryer to heat up the drying agent present and thus extract moisture, while the other adsorption dryer is used for drying the wet compressed gas from the compressor, after it has been cooled and condensate has been withdrawn from it.
  • the regeneration and drying phases can be alternated between the adsorption dryers to guarantee the continuity of the dryer.
  • the device further comprises an ejector-manifold.
  • An ejector-manifold comprises a main channel through which a fluid can flow and two suction channels that are in fluid-mechanical communication with the main channel.
  • the ejector-manifold is configured and connected such that wet compressed gas, originating from a compressor, is allowed to flow through the main channel.
  • the two suction channels are each connected to a connection of a respective adsorption dryer. Due to the negative pressure principle just explained, in combination with the arrangement and position of the valves, a portion of the compressed gas that has already been cooled and has passed through an adsorption dryer will be mixed with wet and hot compressed gas directly originating from the compressor. This is achieved by positioning the set of valves such that this portion can be mixed with the wet and hot compressed gas, while the other portion, hence the portion that is not mixed, is passed to the drain.
  • the ejector-manifold can be connected to the adsorption dryers such that, in the two drying phases, the portion that will be mixed via the suction channels, is successively passed through the cooler and water separator and through the second adsorption dryer for the first drying phase and through the first adsorption dryer for the second drying stage, respectively.
  • This arrangement will hereinafter be referred to as the first configuration.
  • the ejector-manifold can be connected to the adsorption dryers such that, in the second drying phases, the portion that will be mixed via the suction channels is successively passed through the cooler and water separator and through the first adsorption dryer for the first drying phase and through the second adsorption dryer for the second drying stage, respectively.
  • This arrangement will hereinafter be referred to as the second configuration.
  • the wet compressed gas will be successively passed, concerning the first regeneration stage, to the first adsorption dryer, the first suction channel, and the cooler and the water separator, and concerning the second regeneration stage, to the second adsorption dryer, the second suction channel, and the cooler and the water separator.
  • the positions of the valves or ventils are set, for the regeneration phases, such that the main channel of the ejector-manifold is closed off.
  • the wet compressed gas will be passed, concerning the first regeneration stage, to the first suction channel, the first adsorption dryer, the cooler and the water separator, the second adsorption dryer, and finally the drain, while concerning the second regeneration stage, the wet compressed gas is passed to the second suction channel, the second adsorption dryer, the cooler and the water separator, the first adsorption dryer, and finally the drain.
  • the main channel of the ejectormanifold is also closed off.
  • the portion of the dried compressed gas that will be mixed with the wet and hot compressed gas amounts fifteen to twenty five percent of the dried compressed gas, and preferably twenty percent thereof.
  • the volume or mass of wet and hot compressed gas at the input corresponds to one hundred percent volume or mass, and thereof, fifteen to twenty-five percent, and preferably twenty percent, will circulate internally and one hundred percent will flow out through the drain.
  • other ratios are not excluded, depending on the load of the dryer.
  • a first advantage of the device described above for drying a wet compressed gas originating from a compressor is that only a single cooler and water separator is required, due to the use of an ejector-manifold. This not only makes the device more energy-efficient compared to known devices, but also less expensive and less complex to assemble.
  • An additional component such as a cooler and water separator, as known in the state of the art, makes the configuration of the set of lines and valves more complex, which means that the innovative device described above is indeed less complicated to assemble. This further reduces the risk of making mistakes during the production process of the drying device.
  • the adsorption dryers and more specifically the drying agent present, can be generated with hot compressed gas.
  • the adsorption dryer through which the portion of the derived dried and cooled compressed gas flows can be further generated, which is an additional advantage over the state of the art device.
  • this corresponds to the first adsorption dryer
  • this corresponds to the second adsorption dryer.
  • the portion that is diverted is dry and cooled gas, which indeed ensures further drying of drying agent, present in the respective adsorption dryer.
  • Another advantage for both configurations is that the regeneration and drying phases do not depend on the heat present in the hot compressed gas at partial load or low load of the compressor.
  • the device further comprises a measurement module configured to determine a regeneration status of the adsorption dryers.
  • the measuring module is, for example, a dew point meter, and/or a set of a pressure, temperature and differential pressure meter. Via such a set, the dew point can be determined indirectly.
  • the device may further comprise a control module which will control the set of valves or ventils based on the determined or derived regeneration states.
  • the control module may also be external to the device.

By allowing a fluid, hence a gas or a liquid, to flow through the inlet 800 to the outlet 803, which corresponds to the main channel of the ejector-manifold 107, a negative pressure is created at the suction channels 801 and 802. As a result, a fluid present in a line connected to the suction channels 801 and 802, will be sucked in.
