Definitions
- the invention relates to a method for operating an electrostatic precipitator.
- Electrostatic precipitators find in the most diverse technical processes for dedusting of gases use. This is a Package of deposition electrodes arranged in the gas stream. Between These deposition electrodes are preferably wire-shaped Inserted between the electrodes in each case parallel connected spray electrodes on the one hand and the precipitating electrodes on the other hand, a high DC voltage in the order of about 50 kV applied becomes. As a result, the gas molecules are ionized and give then their charge to the dust particles contained in the gas stream which are negatively charged and thereby to the positively charged part of the electrodes are pulled. There They can be made by vibration or by stripping devices be dissolved and then fall down in a dust collector.
- DE 42 22 069 A1 discloses a method for operating a Electrostatic precipitator and an electrostatic filter to carry out the Procedure described.
- a desired spark gap which is another electrical High voltage field builds up.
- the desired spark gap is operated in an area that is dust-free, but otherwise all major operating parameters of the media stream subject. This should on the one hand smoldering fires within of the electrostatic precipitator are avoided, on the other hand should thereby always the operating voltage of the electrostatic precipitator be kept as close to the rollover limit.
- US-A-4 432 061 discloses a method of operating electrostatic precipitators. wherein each electrostatic precipitator is associated with a microcomputer system which coupled with a main computer. This optimizes strategies for the whole arrangement to achieve optimal efficiency.
- the object of the present invention is therefore a method to create an electrostatic precipitator on easy way to safely adhere to the limits for the Ensures particle emission.
- the real electrostatic precipitator becomes a filter model transformed, the at least one input zone, at least a central zone and at least one exit zone, wherein each of the at least three model zones a predefinable Characteristic is assigned.
- this characteristic is the energy supply for a predetermined number of these Model zones depending on the set point of the particle emission regulated.
- Modeling results in a simplification of the algorithms and a shortening of the optimization period for the relevant electrostatic precipitator.
- the filter model 2 comprises in the illustrated Embodiment an entrance zone 2a, a Center zone 2b and an exit zone 2c.
- the entrance zone 2a which contains the steps 1a and 1b of the real filter correspond, has a high, inhomogeneous dust concentration in the exhaust. Charging as many particles as possible Affects the effectiveness of the middle zone 2b and the exit zone 2c.
- the middle zone 2b consisting of the stages 1c and 1d of the real Filter 1 is formed, has a significantly lower dust concentration (about 1/20). In the middle zone 2b can In rare cases, a re-spraying occur. Under re-spray one understands the end of the linear voltage rise despite increasing the current.
- the choice of operating mode for the inverse transformation of the filter model 2 in the real filter 1 depends on the calculated Strength of re-spraying in the corresponding model zones from.
- the gradients of the emission (or opacity) over the partial electrical power educated This requires the electric power in all Zones one after the other at the current operating point slightly be varied.
- the gradients of the three model zones are one Measure of the influence of a model zone when changing the electrical Power on the particle emission.
- the Power setpoints of model zones 2a, 2b and 2c optimized so that all three gradients are the same size and the desired Emission value is reached exactly. At this operating point becomes the electrostatic filter with the minimum possible Power operated at the prescribed or desired Emission value is just reached.
- fuzzy logic For a specific search of the optimal operating point has become proven the use of fuzzy logic.
- Another advantage of using fuzzy logic is the simple realizability of unbalanced controllers Change the membership functions of a signal. An increase Emissions require a fast, strong reaction the system because of the risk of exceeding the limit value, whereas significantly reducing electrical power more time is available. By the use of Fuzzy logic thus increases the reliability.
- the actual values are the mean value of the particle emission also uses the peak values and the instantaneous values.
- the Viewing the current values allows a quick response on rising values due to unpredictable Process changes (eg sootblowing). Monitoring the maxima prevents unwanted or unauthorized emission peaks even with periodic or recurring events (eg plate knocking).
- the High voltage power supplies of the electrostatic filter crosslinked wherein an optical Profibus 5 was selected as the transmission system.
- an optical Profibus 5 was selected as the transmission system.
- the energy management runs on a personal computer 6, which is shown in the Exemplary embodiment under the operating system Windows NT® is operated.
- an automation system eg. Eg Simatic® S7.
- the individual high voltage supplies contain a set of parameters that activates upon loss of data communication becomes.
- B. Operation with nominal current deposited become. If the emission values are exceeded by a predefinable Value becomes one for all high voltage supplies Current increase causes, regardless of the ongoing optimization. In a second stage can be at a further increasing Particle emission in all high voltage power supplies of the Rated current can be activated.
- the user-friendly user interface of FIG Recognize the software used in the personal computer 6.
