Definitions

  • the invention relates to a method for optimizing an electrostatic filter system.
  • electrostatic filters For the separation of dust, electrostatic filters have been known for a long time, in which the dust particles are electrically charged and deposited on electrodes. The separation performance is roughly proportional to the square of the filter voltage. Control methods and circuits for such filters are known for example from Siemens magazine 1971, pages 567-572.
  • electrostatic precipitators that consist of a series of individual chambers that are connected in parallel and / or in series. If you provide a separate power supply system with control for each of these chambers, you can see the entire system from one Think set of individual electrostatic filters composed. For reasons of keeping the air clean and / or recovering valuable useful dust, it is often of the greatest interest in an electrostatic precipitator to keep the separation efficiency and thus the degree of dedusting at a predetermined value. For this purpose, the dust load of the smoke or gas leaving the system can be measured and then intervened accordingly in the system.
  • the object of the present invention is to optimize an electrostatic filter system with regard to energy expenditure and separation.
  • the electrical energies supplied to the individual electrostatic filters are automatically changed iteratively in such a way that the total sum of the energies tends to a minimum for a given dust load at the system outlet.
  • the dust load to be specified is automatically determined by comparing the total energy to be used with the amount of usable dust that can be separated.
  • the separating power is distributed to the respective filter in such a way that the most favorable efficiency - i.e. electrical effort for the separated amount of dust - results.
  • a master controller controlling dust loading and energy minimum is advantageously superimposed on the energy controllers of the individual filters, which regulates the reference variables for the controllers.
  • the individual controllers are preferably designed as microcomputer systems which are connected via a collective bus to a master computer serving as a master controller.
  • the schematically shown electrostatic filter system consists of the individual filters 1, 2 and 3; the gas stream 6 to be cleaned flows through the individual filters 1 to 3 one after the other in the direction of arrow 7.
  • each electrostatic filter 1 consists of the actual filter part 11 with the electrodes for separating the dust and a voltage supply 12, which is constructed in a manner known per se from a thyristor actuator connected to an AC network, a high-voltage transformer and a secondary-side high-voltage rectifier .
  • a thyristor actuator connected to an AC network, a high-voltage transformer and a secondary-side high-voltage rectifier .
  • the dust load prevailing at the outlet of the system is recorded with a measuring device 5 and the degree of dedusting D i is compared in a master controller 4 designed as a computer with a predetermined target value D s . This then specifies the individual energy setpoints US via the data bus 41 to the controllers 13, 23 and 33 of the filters 1, 2 and 3.
  • the power E1 supplied to the electrostatic filter 1 can be detected, for example, by the product of the primary voltage and primary current or by the filter sizes on the secondary side.
  • a signal proportional to this power E1 is fed to an energy minimum controller 42 in the master controller 4.
  • the energies E2 and E3 become the Filters 2 and 3 proportional signals fed to this controller 42.
  • the energy of filter 1 is reduced by the amount ⁇ E. This does result in a reduction in the total energy ⁇ E, but at the same time in a reduction in the actual degree of dedusting D.
  • the power E2 supplied to the filter 2 is therefore increased. Although this brings the dedusting level back to the old value D, it results in an increase in the total energy consumption ⁇ E compared to the original state.
  • a different strategy is therefore used at time t3, namely the energy E1 is increased. At the same time, this increases the degree of separation above the required dimension D, so at time t4 the performance of the filter 2 is reduced to such an extent that the predefined degree of dedusting D results again.
  • the required total energy ⁇ E of the electrostatic precipitator system is also reduced for a given degree of dedusting.
  • the method described above is then continued iteratively by changing the individual values during the operation of the electrostatic filter system, so that the system is always at the optimum energy ar works.
  • a further optimization strategy for an electrostatic precipitator with regard to energy consumption and separation is given by placing the cost of electrical energy in relation to the value of the useful dust in the master computer and by using this to specify the degree of dedusting - which must of course be above the legally prescribed standard - is determined.
