Definitions
- the invention relates to a method according to the preamble of Claim 1 and an electrostatic filter according to the preamble of claim 6.
- a generic electrostatic filter is from the same publication known to experience the above problems. Moreover the spray electrode designed as a wire has a comparatively great length on. Accordingly, it is sensitive against vibrations. This affects the choice of possible areas of application.
- the generic electrostatic filter is intended for dedusting gases.
- the invention has for its object a generic To improve electrostatic filters in such a way that they are robust is inexpensive to manufacture and has a high, constant Filter performance allows, as well as specify a method which reliable cleaning of the spray electrode without impairment that ensures filter performance.
- the spray electrode instead of the vibration-sensitive, wire-shaped component has a two-stage configuration the spray electrode.
- a first shows Level a comparatively small diameter and one free end on. At this first stage, especially at the free end, the corona is created. This first stage can be comparatively short. The longer one second stage with a larger diameter is only used for Maintaining the electric field so that the first ionized particles reliably at the precipitation electrode can be separated.
- the two-stage design of the spray electrode makes this not only robust and insensitive to vibrations, but also effective also due to the different field line density that the solids are almost exclusively at the first stage attach. Cleaning can therefore be compared to this area smaller overall length can be limited. Therefore enough a correspondingly short-stroke drive of the cleaning body from, which causes constructively simple and inexpensive means can be.
- the energy to the cleaning body on the To run spray electrode along advantageously exclusively from engine's own energies are provided so that additional drive elements - e.g. in the form of electric drives - can be eliminated, which are costly and due to the The effects of heat and vibration can be susceptible to faults.
- a fluid or gas filled expansion body can be provided be thermally connected to the engine and which heats up due to the operation of the engine, with the subsequent Cooling of the engine while it is at a standstill a backward movement of the expansion body and the associated cleaning body, wherein cleaning the spray electrode during this movement he follows.
- a Membrane move the cleaning body into a starting position moved so that when the engine stops, if the positive or negative pressure can no longer be maintained is the backward movement of the cleaning body takes place.
- This backward movement can be caused by the volume reduction of the expansion fluid can be effected or by the Spring force of the membrane or an additional spring, wherein during the engine operation of the cleaning body against the Effect of the spring is held in a position in which it is the Spray electrode is not present, so that an optimal separation performance of the electrostatic precipitator is ensured with the engine running.
- the cleaning body and the connected movable components as a spring - mass - System design, so that with certain vibrations of the Motors a resonance frequency of this spring - mass system is achieved, which causes the cleaning body to vibrate, so that its cleaning motion along the first Stage of the spray electrode.
- this first stage advantageously has a constant one Cross-sectional contour, so that always a good contact of the cleaning body be ensured at this first stage can. It depends on the manufacturing process chosen the spray electrode is not perfect identical cross-sectional constancy over the entire length of the first stage attainable. For example, when casting the electrodes may need a certain draft the removal of the cast electrode body from the Lighten mold.
- the invention proposes a regular one Cleaning without an expensive sensor system or an additional to achieve the required timing device by always at certain operating conditions of the engine of the cleaning body is moved along the spray electrode. Besipiellus Such a cleaning cycle when the engine is not running to be triggered. Even with relatively long operating times, such as those used in commercial vehicles how trucks, buses or taxis can occur this way regular, sufficiently frequent cleaning the spray electrode ensured to be consistently good To ensure filter properties of the electrostatic filter.
- the constant high filter performance is ensured by this regular Cleaning achieved and can also are supported that the cleaning body during engine operation generally not along the spray electrode is moved and accordingly the spray electrode in its Performance is not affected.
- the cleaning body with the engine's own energy in one Starting or rest position to move in the distance to the tip of the spray electrode forming the corona and from which he cleans the spray electrode when the engine is stopped starts.
- Fig. 1 is a crankcase ventilation of an internal combustion engine shown, the vent gases through an electrostatic filter 1 be directed.
- the electrostatic filter 1 has a spray electrode 2, while that surrounding the spray electrode 2 Housing serves as a precipitation electrode 3.
- the spray electrode 2 is configured in two stages and has one freely ending first stage 4 with an almost constant cylindrical Cross-section that is comparatively small Has diameter and a short axial length.
- first stage 4 is followed by a second level 5, which is about their Length slightly flared, with the entire spray electrode with the wide end of the second stage 5 on the housing is fixed and held.
- the electrical field line density greatest in the area of the first stage. Forms there a corona in particular at the free end, leading to the Ionization of the particles to be separated is used. In the further These ionized particles pass through the course of the gas flow the electric field between the spray electrode 2 and the Precipitation electrode 3 and led to the precipitation electrode 3 deposited. To maintain the electrical Feldes is the field line density, as determined by the second stage 5 is generated, sufficient.
- the two-stage design of the Spray electrode 2 causes very good vibration resistance compared to the vibrations generated by the internal combustion engine.
- the first stage 4 is regularly a cleaning body 6 cleaned, which encompasses the first stage 4 and as a wiper is movably supported along this first stage 4.
- a cleaning body 6 cleaned, which encompasses the first stage 4 and as a wiper is movably supported along this first stage 4.
- the cleaning body 6 attached to an arm 7, the again from a boom 8 a movably mounted Sleeve 9 is worn.
- the sleeve 9 is held by a compression spring 10 acted upward in the drawing, ie in the held in the position shown in the drawing.
- an expansion body 11 a for example with the coolant circuit of the engine is connected or, as shown in Fig. 1, the is heated by the air present in the crankcase, and in which the resulting engine heat expands a liquid or gas inside it. Consequently moves a plunger 12 of the expansion body 11 the sleeve 9 and thus the boom 8 and the arm 7 against the effect of the compression spring 10 so that the cleaning body 6th is removed from the first stage 4 of the spray electrode 2.
- the cleaning body is in this operating position of the engine 6 at a distance from the spray electrode 2, so that whose function is unaffected and optimal separation results can be achieved.
- the fluid contracts in the expansion body 11. If the sleeve 9 is firmly connected to the plunger 12, can the return movement of the cleaning body 6 in this way alone be effected. Otherwise, the sleeve 9 by the compression spring 10 pushed back into their position shown in the drawing.
- the cleaning body 6 is at the first stage 4 the spray electrode 2 in the one shown in the drawing Position moves and brushes impurities from the first stage 4.
- the "threading" of the cleaning body 6 onto the spray electrode 2 is through a funnel-shaped guide surface on the cleaning body 6 relieved. Especially if different from the procedure described cleaning during Engine operation is carried out, vibration-related deviations on the optimal alignment of the two components to each other be balanced by the funnel-shaped guide surface.
- the expansion body 11 can in a modification of the Embodiment may be provided, the expansion body to be connected to a pressure line of the engine.
- a pressure line of the engine For example can be caused by the oil pressure built up by the engine or by a negative pressure, e.g. B. when accelerating, a first movement the sleeve 9 are effected in the manner described and the corresponding return movement when the Motor can by a spring comparable to the compression spring 10 be effected.
- Fig. 2 shows a second embodiment of the invention, which basically identical to that of Fig.1. However runs the arm 7 at a greater radial distance from the first Level 4 of the spray electrode 2. Even if the cleaning body 6 of the spray electrode 2 is applied in this way Design of a corona at the free end of the first stage 4 hardly disturbed, because the arm 7 the correspondingly large distance having.
- the boom 8 has a first section 8a, of the cleaning body 6 in relation to the first stage 4 extends radially outwards and thereby the distance of the Armes 7 determined by the first stage 4 of the spray electrode 2.
- a second section 8b of the Boom 8 provided the connection to the expansion body 11 to create.
- the cleaning body 6 along the first Stage 4 of the spray electrode 2 moved upwards, removed itself from the free end of the first stage 4, so that form the corona almost undisturbed at this free end can and thus the desired cleaning properties of the Electro filter 1 are ensured. If on one of the already then described the cleaning body 6 is moved back, it brushes the impurities from the first Level 4 off without getting completely from the first level 4 remove so that the subsequent threading between the first stage 4 and the cleaning body 6 is avoided and Malpositions cannot occur at all.
- FIG. 3 an embodiment is shown, which opposite the examples of FIGS. 1 and 2 are not temperature-dependent. but works pressure-dependent: a pressure control membrane, or membrane 14 is on their outer circumference 15 is set and in Fig. 3 with solid Lines shown in a cleaning position in which the cleaning body 6 the free-ended tip of the first stage 4 the Spray electrode 2 is present.
- the cleaning body 6 is as peg surrounded by an elastomer.
- the membrane 14, such as represented by dashed lines, in a release position are moved in which the cleaning body 6 from the free End of first level 4 is removed and free training allows a corona at this free end.
- the membrane 14 is part of a pressure cell 16, which has a bore 17 with the surrounding pressure, for example atmospheric pressure, communicates.
- the inside of the bore 17 Pressurized can 16 and within the crankcase ventilation prevailing pressure through the inside of the Electrofilter 1 acts on the membrane 14, the membrane 14 deformed against its own elasticity and between the release position and moved the cleaning position back and forth.
- the pressure can can vary of the embodiment shown in Fig. 3 can be connected to other pressure conditions, for example by the bore 17 with other pressure ranges within of the entire engine is connected or by the Pressure cell 16 is not within the pressure chamber of the crankcase ventilation is arranged, but in another Pressure chamber. Then, however, would be an additional pressure control membrane required for the crankcase.
- a combination of several of the exemplary embodiments mentioned is possible, e.g. by applying overpressure to a membrane and on the other hand, a vacuum is applied to particularly to overcome high spring forces or particularly long To enable ways of the cleaning body.
