Definitions
- the invention relates to a method for influencing particles in a gas flow . Furthermore, the invention relates to a device for performing the method.
- lamella and centrifugal separators are preferably used for droplet separation.
- a change of direction is forced on the gas flow, which the liquid drops do not follow and are thus deposited on a wall and can be removed from the gas flow.
- electrostatic filters are preferably used, which, however, cannot be used in the specified temperature ranges.
- An essentially temperature-independent device for separating drops from a gas phase is described in DE 87 01 718 U1, a magnetic field being generated in a flow region by applying electrical voltages. Corresponding magnetic or static charges are also described in DE 11 37 980 A1 and DE 31 51 125 A1. Further devices and methods for influencing particles in a fluid by generating an electric field can be found, inter alia, in US 4,342,574, US 4,398,931, US 4,255,323 or EP 0 501 138.
- the above-described methods and apparatus are not suitable for the high temperature range as well as any kind of particles or droplets.
- some of the previously known methods are not suitable for influencing particles or drops with diameters smaller than 10 ⁇ m.
- the present invention has for its object to provide a method for influencing located in a flow of gas particles, the manufacturing is simple and economical and feasible, can be used in extremely high temperature ranges and also to influence of particles, in particular liquid drops , less than 10 ⁇ m can be used. Furthermore, the invention is intended to provide a device for carrying out the method.
- the invention takes advantage of the effect that some materials have as a result of use increased electron mobility occurs in the high temperature range, so that an electric charge sets in. Will at least one surface out such a material introduced into a flow section, so that the Gas sweeps over this surface, provided the surface charge is too is contrary to the pollutant loads, the pollutant is extracted.
- Particles in particular liquid drops , for the purposes of the present invention are the preferred field of application.
- the invention relates to and is suitable for any type of particle, even if it is in other aggregate or intermediate states depending on the temperature.
- a particularly advantageous manner in a flow portion for establishing an electric field are introduced at least two mutually facing surfaces due to high temperature in each case different electric charge generating materials.
- the electric field can be used to influence the particles , for example to give drops a certain direction, to guide them to a certain surface and to separate them, or the like.
- the at least one surface is advantageously a ceramic.
- the at Materials used at high temperatures are mostly ceramic Materials. These are used either in highly pure form or as mixtures.
- the main components are mostly silicon oxide and aluminum oxide.
- Special refractory properties are achieved by adding additional oxides reached. Special properties with regard to resistance to temperature changes and chemical resistance through special machining processes, for example, sintering or isostatic pressing.
- ceramic materials can be classified as electrical insulators, the conductivity of both the composition and the Temperature is dependent.
- isolator properties encounter all ceramics in every temperature range.
- zirconium oxide-containing ceramics from a temperature above 600 ° C as opposite good insulators a very different change in conductivity showing materials that rapidly increase in one with increasing temperature Range of conductors with a resistance in the kiloohm range. This Effect is particularly pronounced with melt-cast ceramics and is based obviously on a given by the special structure of the material facilitated electron mobility.
- oxides from the Row of sub-group elements for example zirconium oxide and the like are therefore preferable.
- thermal emission To build up a field between at least two surfaces of the above The effect known as thermal emission is used.
- particles contained in a gas stream can be deflected, collected, neutralized or otherwise influenced.
- the surfaces can be formed on a wall of a flow section, on an additional element or on a component to be arranged in the flow area anyway.
- the method according to the invention uses special material properties under appropriate temperature and flow conditions in order to deflect, collect or otherwise influence particles of the smallest diameter in a gas stream, the measures according to the invention being economical and simple to implement.
- a device-side electrostatic precipitator is proposed with the invention that can be used or formable in a flow section and consists of at least one the electric field-generating surface of an electric charge generating material at high temperatures.
- this electrical separator has at least one ceramic surface which contains constituents of zirconium oxide.
- the electrical separator can be an additional component, represent a surface formed on a component present in the flow area or a solid functional element, be formed in the area of a wall of a flow section and the like.
- a special embodiment of the invention provides that plates arranged parallel to one another form a corresponding electrical separator. It is proposed that a plurality of plates flow through alleys.
- the alley width is chosen so that the probability of gas / surface contact is maximized taking into account the gas velocity.
- other shaped elements can also form corresponding flow-through streets.
- the alley width is related to the speed of the gas and the electric fields. The higher the speed and the narrower the alleys, the lower the electric field can be. Conversely, a low speed with electrically charged particles can also provide good separation when gases flow through between molded elements.
- the invention provides a simply constructed electrical separator for the separation of liquid droplets in a gas flow, even of the smallest diameter, which can be economically realized by simply forming surfaces with materials with corresponding properties. In combination with fluidic effects, very high efficiencies can be achieved.
- non-oxide Ceramics such as carbides, silicides, nitrides or the like. It is beyond that in the context of the invention, the said effect of charge-generating Reinforcing surface due to high temperature by the additional Applying electricity.
- a plate pack is shown schematically, which consists of a variety there are parallel plates that clear alleys between them. the distances are adjustable, for which adjustment bolts and washers can be used. This Fastening areas can lie outside the area through which the flow flows or be disguised with respect to the flow.
- the plates 2, 3 can be made of materials that produce different charges when flowing with very hot gases, so that an electric field can be built up. In the manner described, this can considerably promote the separation of particles, in particular liquid drops .
- the separator 1 has the plates 2, 3, which are adjustable in a housing 4 by means of adjusting bolts 5, 6 to form correspondingly narrow streets. In the exemplary embodiment shown, the flow takes place in the direction of arrow 7.
- the plates can also be hung in flow cross-sections, in grooves used or otherwise attached.
- the plates can be emitted as conductive / insulating plates or with reversed polarity.
