Definitions

  • the present invention relates to a multi-stage high pressure compression installation which consists of at least two compressors which are connected in series by means of a pipe.
  • This type of high pressure plant is for example used in the field of the production of PET bottles which requires the use of compressed gases with a pressure above 2000 kPa.
  • a second reservoir is preferably provided here which serves as a buffer for a network of users.
  • the drive of the first compressor is controlled on the basis of the pressure prevailing in the aforementioned first reservoir, while the drive of the overpressure compressor is controlled on the basis of the pressure prevailing in the second tank.
  • control involves the fact that a compressor concerned does not rotate under load, and therefore compresses gas, only when the pressure in the corresponding reservoir is lower than a preset pressure.
  • a disadvantage associated with a high-pressure compression installation of the known type lies in the fact that this installation has a relatively low reaction rate to large fluctuations in the consumption of the compressed gas.
  • the pressure in the second reservoir will drop until a value lower than the level previously set for the switching of the overpressure compressor to switch to a load regime.
  • the overpressure compressor rotates under load, it sucks up a quantity of the compressed gases from the first reservoir, which, in a second step, the gas pressure prevailing in this first reservoir drops to a value lower than the level set at beforehand, so that the first compressor is loaded accordingly too.
  • the gas pressure at the output of the compressor overpressure will not be constant at first and that until the first compressor rotates at full speed and therefore produces a quantity of compressed gas equal to the amount of gas sucked by the compressor overpressure for the subsequent compression of said gas.
  • Another drawback related to a known multi-stage compression installation lies in the fact that the first reservoir between the two compressors must be relatively large in order to prevent, during the charging of the superpressure compressor, the consumption of all the compressors. of gas prevailing in the first tank before charging the first compressor.
  • the object of the present invention is to provide a solution to one or more of the mentioned disadvantages as well as others.
  • the present invention relates to a multi-stage high pressure compression installation which consists mainly of a main gas pipeline which opens into a buffer and in which at least two compressors are connected in series with each their own drive, the installation being equipped with means for determining the pressure prevailing at the outlet of the main pipe, said installation being connected to a control box, characterized in that this control box is connected to at least two of the aforesaid compressor drives and in that it provides a control of the compressors such that the latter rotate together under load or together without load.
  • An advantage of the present invention lies in the fact that the different compressors are jointly loaded on the basis of the pressure prevailing in the aforementioned buffer tank, so that when loading the compressor which represents the stage In an automatic manner, compressors located in the lower compression stages are jointly loaded.
  • the joint loading of the various compressors makes it possible to maintain constant, or almost constant, the pressure prevailing between each of the different compressors, so that one is confronted with relatively small fluctuations of the gas pressure at the exit of a compressor.
  • An additional advantage related to a multi-stage compression installation according to the invention, in which the different compressors are controlled to be driven simultaneously, lies in the fact that the quantity of gas to be provided between the two compressors is relatively small, since the consumption of compressed gas by a compressor can always be compensated by the supply of compressed gas by the compressor of the previous stage.
  • Another advantage of a multi-stage compression installation according to the invention lies in the fact that a single pressure sensor can suffice for its control, where the known multi-stage compressors are equipped with a pressure sensor by compression stage.
  • FIG. 1 shows, schematically, a multi-stage compression installation according to the present invention
  • FIG. 2 represents a variant of FIG.
  • a multi-stage high pressure compression installation 1 consists mainly of a gas main pipe 2 which opens into a buffer 3 and in which, in the present case, two volumetric compressors 4 and 5 are connected in series.
  • the first compressor 4 is for example a screw compressor which serves as a low pressure compression stage
  • the second compressor 5, which is also called the superpressure compressor is for example a piston compressor which serves as a compressor. high pressure compression stage.
  • the aforementioned buffer 3 can be made in the form of a reservoir or the like which is connected to a user network 6 and in which, preferably, means 7 are provided which make it possible to determine the gas pressure prevailing in the reservoir. and which are connected to a control box 8 which is for example an electronic box.
  • the aforementioned means 7 for determining the pressure can also be mounted, if desired, at the exit of the main pipe 2 or in the user network 6.
  • the aforementioned means 7 can be made in different forms, for example by a direct measurement of the pressure using a pressure gauge or by means of an algorithm which makes it possible to determine the gas pressure prevailing in the buffer, for example from a measurement of the temperature.
  • the above-mentioned compressors 4 and 5 each respectively have a drive, respectively 9 and 10, which are each connected to the aforementioned control unit 8 and which are for example made by electric motors or other kinds of motors.
  • compressors 4 and 5 are, in the present case, of the fixed speed drive type and they are preferably dimensioned so that, when they are each driven at their fixed drive speed, they both compress one and the same. amount of gas per unit of time.
  • control box 8 thus fulfills, as it were, the role of an electronic transmission shaft connecting the two compressors 4 and 5.
  • the aforementioned control unit 8 is provided with a control such that, when the gas pressure prevailing in the above-mentioned buffer 3 drops below a previously set minimum value, the compressors 4 and 5 are charged, of such so that they compress gas and so that the gas pressure prevailing in the buffer 3 can be re-established.
  • FIG. 2 shows a variant of a multi-stage compression installation 1 according to the invention, by which the compressors 4 and 5 can be driven at a variable speed and by which the drives of the compressors 4 and 5 are connected. from each other using an electrical conduit 11 which in the case shown passes through the control box 8.
  • control provided in the control box is such that the compressor 5 which forms the last overpressure stage is driven with a speed which depends on the gas pressure prevailing in the buffer 3, while one or more other compressors 4 in the main pipe 2 are driven according to the drive speed of the aforementioned compressor 5.
  • control is preferably of the type by which the two compressors 4 and 5 compress the same amount of gas per unit time, so that the amount of gas present in the main pipe 2 remains constant, or substantially constant between the two compressors 4 and 5, during normal commissioning of the multi-stage compressor.
  • each of the compressors 4 and 5 can be embodied as one or more elements of i -pressure connected in parallel or in series and driven by the same drive.
  • the low pressure stage and the high pressure stage S can be realized as two separate compressor groups which are connected in an electronic manner by a common control unit 8 or by a simple electrical conduit which connects the housings each group.
