Definitions

  • the present invention relates to a method for producing compressed fluid.
  • compressed air production plant As a known compressed air production plant, there is for example that described in the article entitled: " Compressed air, feedback on a sale by cubic meter, published in ENERGIE PLUS, n ° 224 of April 15, 1999 , periodical of the Technical Association Energy Environment. It comprises at least two compressors whose discharge side is connected to a compressed air network; at least one of these compressors is fixed speed and is dimensioned so that it operates permanently at 100% of its capacity; another is variable speed and is adjusted so that it adds to the flow of fluid required. This last compressor is started or stopped according to the pressure found in the air network. When the installation includes more than two compressors, only one is variable flow.
  • the European patent application EP 1 249 675 describes a method of controlling a compressor battery by means of a frequency converter.
  • this method often requires a financial investment that is not compatible with the expected energy gain, and it is only possible for higher-end installations such as air conditioning stations or cold production systems.
  • US 2002/182082 discloses the use of a physical system of 4 valves (SV1, SV2, SV3, SV4) which modifies the production capacity of compressors. Specific rules for controlling the 4-valve system are described.
  • the PID control method described in US 2002/182082 used for the control of the 4 valves is based on the number of maximum restarts of the different compressors by imposing a running time per hour of 25 minutes.
  • the present invention aims to overcome the drawbacks mentioned, and to provide a method implementing a compressed fluid supply installation that is economical, especially with regard to energy consumption. Another object is the implementation of a compressed fluid supply installation that has a low maintenance cost.
  • the compressors used in the installation that is the subject of the present invention are preferably of the "all-or-nothing" type.
  • the compressors are identical.
  • compressor-type all-or-nothing it refers mainly commercial compressors classified in this category and more particularly the screw compressors.
  • Compressed fluid means a fluid whose total pressure is greater than one atmosphere and more particularly: air, oxygen (O 2 ), nitrogen (N 2 ), argon (Ar), dioxide Carbon monoxide (CO 2 ), carbon monoxide (CO), helium (He), nitrous oxide (N 2 O), nitric oxide (NO), nitrous oxide oxygen, carbon dioxide and oxygen, nitrogen and carbon monoxide, helium and oxygen, such as for example, mixtures (50% by volume (v / v) N 2 O + 50% v / v O 2 ), (5% v / v CO 2 , 95% v / v O 2 ), (200 to 800 ppm NO in N 2 ), (78% He + 22% v / v O 2 ), (65% He + 35% O 2 ), (80% v / v He + 20% v / v O 2 ) or the mixtures of nitrogen and carbon dioxide.
  • air oxygen
  • O 2 oxygen
  • N 2 nitrogen
  • the installation as defined above is a compressed air production facility.
  • predetermined choice protocol means all the measurements and / or counts and / or calculations to be carried out which give rise to the choice of changing or not to change, the state of the one or more compressors of said installation, when the pressure observed in the compressed fluid network, crosses one of the two limit values which are the low threshold pressure (PSL) and the high threshold pressure (PSH).
  • PSL low threshold pressure
  • PSH high threshold pressure
  • the installation as defined above comprises from two to six compressors.
  • the installation as defined above comprises at least one data acquisition means capable of dating and determining each change of state of each compressor permanently or discontinuously over time. .
  • the choice protocol is defined by the following set of parameters:
  • TMCG overall load running time
  • control means comprise a programmable controller characterized in that it comprises a central unit comprising a memory and a computer program capable of selecting, when the pressure P found exceeds the pressure thresholds PSH or PSL, the compressor or compressors which, at a given instant t, must be either started, or switched to idle, either switched on load, or stopped, thanks to the choice protocol as defined above.
  • This programmable automaton optionally comprises means allowing its remote control.
  • the compressors are connected in parallel by their discharge side, to a buffer tank of compressed fluid via a first connecting line, said buffer tank being connected to the compressed fluid network by a second connecting line provided with a shut-off valve.
  • the first connecting line is preferably provided with a filter.
  • the number N C is generally between 2 and 8.
  • N C is determined on the basis of a homogeneous distribution of compressor start-ups in a given time, it is possible to determine a time during which the compressor is stopped and can not be started again. This duration, called time remaining before the next available start or TRDEM, expressed in hours, is therefore less than (1 / N c ) h. TRDEM is 0 when there has been no start during the previous hour.
  • TMAV is generally greater than or equal to 30 seconds.
  • the TMG or overall running time expresses the number of hours during which a given compressor has walked since the start of the installation.
  • the process as described above is particularly suitable for the production of compressed air.
  • the subject of the invention is a computer program for carrying out the method as defined above.
  • This installation 2 comprises three compressors 4, 6, 8, each provided with switching means, 32, 34 and 36 able to switch them in one of three states that are the stop, the idle and the run in charge, which are connected in parallel to the inlet 10 of a buffer reservoir 12 of compressed fluid via a first connecting pipe 14 provided with a filter 16.
  • An outlet 18 of the buffer tank 12 is connected to a user network of compressed air (not shown) via a second connecting line 20 provided with a shut-off valve 22.
  • the compressors 4, 6, 8 are lubricated screw compressors. Such compressors are, for example, compressors of the DSD 201 / 7.5 bar type sold by the company KAESER.
  • the installation 2 further comprises a source of electrical energy, in this case a three-phase power source 24.
  • the installation 2 comprises three first lines 26, 28, 30 of three-wire connection. Each of the first connection lines 26, 28, 30 connects one of the compressors 4, 6, 8 to the current source 24.
  • a pressure sensor 54 of the fluid is placed downstream of the compressors 4, 6, 8 in the fluid network, for example in the buffer tank 12.
  • the installation 12 further comprises a control device, in this case a CMD programmable controller.
  • This CMD control device comprises an inlet 56 which is connected to the pressure sensor 54 by a sensor line 58, in order to record the fluid pressure P established in the fluid network.
  • the CMD control further comprises three outputs 60, 62, 64 which are connected to first 66, second 68 and third 70 control lines of the switching means 32, 34 and 36.
  • the outputs 60, 62, 64 and the associated control lines 66, 68, 70 are adapted to control the tilting of the compressors 4, 6 and 8.
  • the outputs 60, 62, 64 are controlled by a CPU CPU of the CMD control as a function of the fluid pressure P.
  • the programmable logic controller CMD comprises a memory MEM in which the high pressure thresholds PSH and low pressure PSL are stored, and the set of acquired data relating to the parameters and variables indicated above and a program PRG of control of the installation capable of selecting, when the pressure P found exceeds the pressure thresholds PSH or PSL, the compressor or compressors which, at a given instant t, must be either started or spent idling or passed on by load or arrested.
  • the memory MEM stores, for each of the compressors 4, 6, 8, the total operating time of the compressor 4, 6, 8 associated.
  • the PRG program implemented in the CMD control controls the switching means 32, 34 and 36 in an exclusive branch mode.
  • the CMD control is further provided with means for detecting a failure of one of the components of the installation 2.
  • These means are connected to a telephone line 80 to warn the maintenance personnel in the event of a failure.
  • the Figure 2 represents an example of the pace over a time period of one hour, the pressure P prevailing in the air network and two diagramfdes change of state of three compressors in parallel (CO1, CO2, CO3), according to invention (new law of order) and according to the state of the art (old law).
  • the ordinates of the two diagrams represent the different states of the three compressors: (MC is on load, MV is idle, SB is off).
