Definitions

  • the following invention relates to a method for the intelligent control of a compressor unit with liquid injection, which is equipped with a heat recovery with the aim of maximizing efficiency.
  • CN 101 43 5420 (A ) shows a system for heat recovery and circulation on an air compressor.
  • a system which causes the cooling of the air compressor by means of cooling water comprising a fluid circuit of the fluid to be injected, said fluid passes through at least one heat exchanger for heat recovery, wherein upstream of the compressor of the compressor system, a control valve and behind the heat exchanger of the heat recovery WRG-side control valve is arranged and controls an electronic control unit by means of an algorithm at least one of the two control valves and the required temperatures for the material flows of the heat recovery of the control unit can be entered as a parameter. It is the goal of this disclosure to make a control of the temperature of the cooling water and to realize a good heat recovery.
  • control valve arranged in front of the compressor is in this case mounted directly on the radiator and thus can not be arranged as one in the compressor, by a electronic control unit regulated control valve are considered.
  • the disclosed herein liquid injection compressor system is therefore equipped with a heat recovery, but it is no intelligent control with the aim of maximizing efficiency possible.
  • the focus is on the effective cooling of the air compressor, with the invention only a better heat recovery is to be achieved, the means used for this purpose remain open.
  • the focus remains the cooling of the air compressor. It should only be realized that the dissipated energy is also used meaningfully. Despite all this, the system continues to focus only on the requirements for ideal operation of the air compressor.
  • an oil temperature control valve is provided for this purpose, which, although it can be regarded as a compressor-internal valve, is not electronically controlled in this case. In this way, however, can not realize a regulation for heat recovery in the context of the present invention, which is directed both to a cooling of the compressor, as well as the largest possible energy savings of the overall system.
  • the fluid [1] oil or water
  • a separator [8] separates the compressed air from the fluid, wherein the separated fluid is recycled in a circuit back to the suction side of the compressor.
  • the fluid is recooled to the desired temperature level for renewed injection in an internal heat exchanger [10] (water- or air-cooled).
  • a compressor-side control valve [6] controls the fluid injection temperature [1] to the desired fixed value.
  • oil temperature regulators are used in the prior art as 3/2-way valves, in which an actuated by a wax element slider controls the inflow.
  • the oil temperature controller regulates the temperature of the oil within a fixed temperature interval, and will only ever deliver to the radiator as much oil as is required to achieve the desired oil temperature prior to injection.
  • the temperature of the injected fluid also influences the temperature of the compressed air in the separating vessel [8] and at the same time the temperature of the fluid after compression [2].
  • this heated by the compression process fluid [2] for heating a stream [4, 5] an external heat exchanger [9] is supplied and thereby cooled itself again.
  • the compressor-side and heat-recovery-side control valves [6 and 7] must be coordinated with each other to prevent the fluid temperature after the heat recovery [3] drops below the desired fluid injection temperature [1]. If the heat recovery is not required, the internal heat exchanger [10] takes over the cooling function of the compressor.
  • the temperature level of the fluid after compression [2], which is required for the heat recovery will differ considerably from the required temperature depending on the load operation of the compressor during operation of the compressor system. If the fluid temperature is too low after compression and before the heat recovery, only approx. 35 - 90% of the possible energy is recovered in real operation of the compressor system.
  • An algorithm stored in the control unit controls via at least one control element [6, 7] the fluid outlet temperature after the compression [2] and the fluid outlet temperature after the heat recovery [3] in the form that exactly the temperature level is reached the customer needs to recover the desired amount of heat of the plant.
  • the increase in heat energy (10 - 65%) is significantly higher than the somewhat higher power requirement of the compressor stage (about 2 - 5%) due to an increased fluid injection temperature [1].
  • the temperature level can be lowered again if temporarily no heat is removed by the heat recovery in order to reduce the performance of the compressor again.
  • the energy saving achievable by this intelligent control is on the order of 2 - 60%.
  • the desired outlet temperature could be directly used as the controlled variable of the customer stream [5] are regulated.
  • a flow control of the customer flow through a control element [12], for example, a throttle valve is conceivable that ensures a constant temperature level.
  • the desired temperature (5) of the medium heated by the heat recovery in the control unit (11) is used as an output parameter for the regulation of the temperature of the fluid after compression [2].
  • the table of FIG. 1 shows an example of a comparison of the energy recovery of a conventionally regulated heat recovery and the intelligent controlled heat recovery according to the invention.
  • FIG. 2 In the schematic representation of FIG. 2 is shown on the one hand on the left side of the compressor 13, in which a fluid is injected in the operating state 1. After compression, this fluid is separated in a separator 8 from the compression medium and transferred as fluid in the operating state 2 after compression in the second right-hand area of the system, namely in the heat recovery (WRG).
  • WRG heat recovery
  • the fluid heated by the compression process enters operating mode 2 at an elevated temperature compared to operating state 1, because, depending on the load condition the compressor takes place a defined heating of the injected fluid during the compression process.
  • This heated fluid is now supplied to a heat recovery in a heat exchanger 9, whereby it after passing through this heat recovery process in the operating state 3 cooled after heat recovery by a certain value to be defined again exits.
  • This valve is electrically controllable according to the invention, for example, by an electric stepper motor, which takes the place of the conventional expansion element, and has two inputs A and B.
  • Input A is in this case an input, through which the fluid can be supplied in the operating state 2, bypassing the heat recovery for regulating the temperature of the fluid in the operating state 3 after the heat recovery.
  • Input B is an input to the control valve 7, through which the fluid enters after the heat recovery in the cooled state. That is, via the control valve 7 is a mixture of fluids in the operating state 2, that is at elevated temperature and in the operating state 3 after the heat recovery possible so as to control the temperature to which the fluid has in the operating state 3 after heat recovery.
  • the heat exchanger 9 thus has a cooling medium, for example water, which is present in the operating state 4 before entering the heat exchanger 9 in the operating state 5 with increased temperature after passing through the heat exchanger 9.
  • a cooling medium for example water
  • an additional control element 12 for example a throttle valve, is also provided in the inlet of the heat exchanger 9, by means of which the flow rate of the heat exchanger 9 with the medium to be heated can be controlled.
  • This also serves to control the outlet temperature of the fluid in operating state 3 after heat recovery. There is a higher exit temperature in the fluid after heat recovery when reducing the flow rate of the cooling medium in the heat exchanger 9.
  • the fluid in the operating state 3 after the heat recovery is now fed back to the compressor side of the system, since it is guided for renewed injection into the compressor 13 in a circuit.
  • another control valve 6 Prior to injection into the compressor 13, another control valve 6 is part of the system, which is also electrically controlled. Depending on the desired inlet temperature 1 of the fluid during injection into the compressor 13, this control valve 6 can now either pass on the fluid in the temperature in the operating state 3 after heat recovery or carry out a regulation to reduce the temperature.
  • control valve 7 the control valve 6 for this purpose has two inputs, namely the input A, through which the fluid is supplied in the operating state 3 in a certain temperature level after heat recovery and is thus supplied to the injection.
  • the second input B is preceded by a cooler 10, through which the fluid can be reduced in its temperature in a defined level.
  • the inputs A and B can thus be set a mixing ratio of the fluid between the higher temperature in the operating state 3 and the cooled temperature after passing through the radiator 10 and so adjust the fluid in the operating state of the injection 1 exactly to a desired temperature.
  • both operating states of the valve 6 also apply when using the heat recovery, namely an exclusive flow through the inlet A or a connection of the inlet B and thus a defined cooling of the fluid prior to injection into the compressor 13.
  • the fluid 2 can be performed completely by input B or in a mixing forum through input A and B or completely, bypassing the heat recovery exclusively through input A after compression, since the heat recovery does not remove temperature and thus the temperature after the heat recovery regardless of the valve position of the control valve 7 is constant.
  • the control valve 6 can be operated in the use position of both open valves A and B or in the exclusive opening of the entrance B, as a rule, a cooling of the fluid in the event of a non-occurring heat recovery will be required in principle.
  • valve positions result from the operating states of a heat recovery, which in the use temperature raised or lowered as needed.
  • a heat recovery which in the use temperature raised or lowered as needed.
  • a further control component can be achieved alternatively or additionally by simultaneously throttling the cooling medium in the throttle valve 12 with a displacement towards the inlet A into the valve 6 or to an exclusive conduction of the fluid in the operating state 3 via the inlet A of the valve 6 the heat recovery 9 takes place.
  • the heat recovery 9 takes place.
  • a reduction in the temperature of use of the heat recovery would be achieved by a shift towards the input B of the valve in the control valve 6 before injection, that is, more of the fluid is passed in the operating state 3 after the recovery of heat through the radiator 10 and thus the temperature is lowered before the injection of the fluid 1. Due to the lowered injection temperature 1, there is also a reduction in the temperature 2 after separation in the separator 8 after compression before the heat recovery 9. That is, the fluid enters the heat exchanger 9 at a lower temperature, whereby here the temperature level to be cooled Medium in the output 5 can be reduced.
  • the system according to the invention can respond to changes in the load operation of the compressor 13 in order to maintain the desired use of heat recovery at a defined level. It is here central concern of the invention to make the heat recovery energetically optimal and thus to achieve a much better energy yield of the system of compressor and heat recovery.
  • the throttle valve 12 can also be operated in an advantageous design to reduce the flow rate of the medium to be heated by the heat exchanger 9 such that the temperature in the state 5 after heat recovery reaches the desired value.
  • a startup of the load operation of the compressor 13 causes a temperature increase of the compressor fluid after compression 2 and after deposition in the separator 8.
  • the fluid in the operating state 2 thus has a higher temperature, possibly higher than required for the heat recovery in the heat exchanger 9. It is therefore not useful, as in the previous example, to use the inlet via input A of the control valve 7, since so the heat dissipation of the fluid does not occur through the heat recovery.
  • An increased flow of the medium to be heated via the throttle valve 12 through the heat exchanger 9 is expedient so as to adjust the temperature in the state 5 in the exit 5 from the heat exchanger 9.
  • a decisive control point in this operating state is the position of the control valve 6, since here by an increased diversion of the fluid in the operating state 3 via the radiator 10 and thus in the input B of the control valve 6, the input temperature of the fluid to a desired value in the operating state 1 before Compaction is adjustable. That is, by the cooling of the fluid prior to injection 1 in the compressor, a certain temperature of the fluid is adjusted after the compression in the operating state 2, which corresponds exactly to the specifications to the desired temperature of the working fluid after passing through the heat exchanger 9 in the operating state 5 to reach.
  • Temperature measuring elements are at least provided for the fluid temperature 2 after compression and the fluid temperature 3 after the heat recovery. Furthermore, it is expedient to measure the water temperature 5 according to the WRG, since this should comply with a desired value. If the inlet temperature 4 before the WRG is also variable, a measuring element should also be present here.
  • FIG. 3 an alternative design of the system is shown, in which now the previously arranged as internally on the compressor side heat exchanger 10 is no longer connected in series with the heat exchanger 9, but has a parallel arrangement to the heat exchanger 9.
  • control valves 6 and 7 would change from the previous description in that now the control valve 6 takes over the task to prevent cooling of the compressor by a too low temperature of the fluid 1 at the time of injection. This would be realized by the previously described supply of fluid 2 at the temperature level after compression by the inlet A.
  • Control valve 7 controls the fluid temperature 3 after heat recovery, whereby in turn the temperature of the fluid before the injection 1 and after the compression 2 is dependent.
  • a control valve 12 may alternatively or additionally be provided, which regulates the flow of the medium through the heat exchanger 9. By this regulation can also the heat removal from the fluid and thus the temperature difference between the fluid after compression 2 and the fluid after heat recovery 3 are regulated.
  • a control valve in the system in an alternative design.
  • a waiver of control valve 6 would be possible here, if control of the fluid injection temperature would also be effected via the control valve 12.
