Definitions
- the invention relates to an exhaust gas purification system for the disposal of environmentally harmful and / or toxic gases or vapors, with a reaction space which is connected to a plasma source in which a plasma is formed by the coupled excitation energy, the reaction space and / or the plasma source having at least one input for the feed of gases or vapors and the reaction space has an outlet for the gases or vapors treated in the plasma source and / or in the reaction space.
- Such a device for cleaning exhaust gases has become known from WO 96/23173.
- This device contains a combustion chamber in which a burner is arranged and the fuel gas, oxygen or air and the process exhaust gas to be decomposed are supplied. Above the combustion chamber there is a washroom with a spray nozzle for spraying the sorbent agent.
- the combustion chamber is located inside an outer tube and is delimited by an inner tube, the outer tube also enclosing the wash chamber located above the combustion chamber.
- reaction products created in the combustion chamber are passed between the inner and the outer pipe into the wash room and from there via an exhaust system into the ambient air.
- a disadvantage here is that the plasmas generated often constrict.
- the achievable plasma volume is limited by shielding effects. This also limits the amount of waste gas that can be disposed of, so that the waste gas amounts that can be achieved with the usual combination systems (combustion / thermal decomposition and subsequent washing) cannot be achieved.
- the generation of the plasma must therefore be given particular attention in order to avoid the disadvantageous effects listed above.
- it proves to be disadvantageous that the most favorable plasma parameters for the conversion of the gases or vapors cannot always be set when working under normal pressure.
- a scrubber is required that removes the pollutants that are still present in the plasma after the conversion of the exhaust gas.
- the invention is therefore based on the object of providing an exhaust gas purification system in which an effective and inexpensive disposal of environmentally harmful and / or toxic gases or vapors is made possible using a plasma source which also works at atmospheric pressure.
- the object on which the invention is based is achieved in an exhaust gas cleaning system of the type mentioned at the outset in that the outlet of the reaction chamber is connected to a liquid jet pump, in that the liquid jet pump in the reaction chamber and in the plasma source has a negative pressure generated and that the exhaust gases treated in the plasma or by excited particles together with the liquid passed through the liquid jet pump and mixed therewith are passed out of the reaction space.
- liquid jet pump By using the liquid jet pump according to the invention, a negative pressure in the range from atmospheric pressure to ⁇ 100 mbar can be generated in the reaction space. At the same time, the solid, gaseous and liquid pollutants that are still in the exhaust gas stream after washing out of the plasma are washed out by the liquid jet pump.
- the plasma can be ignited at low pressure and the plasma conditions can be adapted in such a way that the decomposition of the gases or vapors to harmless exhaust gases takes place as completely as possible.
- a decrease in pressure leads to an increase in the plasma volume, but on the other hand the exhaust gas volume is increased so that the residence time is reduced.
- the exhaust gas to be treated can be passed directly through the plasma of the plasma source or it is fed directly behind the plasma source into the reaction space and treated in the so-called remote plasma by the particles excited in the plasma.
- the suction opening of the liquid jet pump has a large cross section, on the one hand to generate the required suction capacity and on the other hand to prevent blockages by solid components of the exhaust gas. This also results in a particularly good mixing of the flow through the liquid jet pump. reached with the exhaust gas emerging from the reaction chamber.
- the negative pressure generated in the reaction chamber by the liquid jet pump is in the range from ⁇ 30 mbar to atmospheric pressure.
- a cooling device is used to prevent progressive heating of the liquid in the liquid circuit.
- the liquid jet pump can thus always generate the necessary negative pressure in the plasma source and in the reaction space, which is required, for example, to ignite the plasma.
- the liquid jet pump is operated with a sorbent, the liquid jet pump being part of a liquid circuit for the sorbent. In this way, media costs can be significantly reduced and disposal efficiency increased.
- the liquid circuit also has a controllable circuit pump for regulating the delivery rate of the sorbent, so that the vacuum generated by the liquid jet pump can be regulated by regulating the delivery rate of the sorbent.
- the circulation pump is preferably designed as a diaphragm pump operated by compressed air, since on the one hand this achieves a high delivery rate and on the other hand a long service life can be guaranteed.
- the reaction chamber and / or the plasma source is provided with at least one supply for additional gases.
- additional gases can be oxygen and / or hydrogen, water vapor, but also other gases. With these additional gases, the effectiveness of disposal can be increased.
- Plasma sources which operate in the microwave range are preferred, since a non-equilibrium plasma (non-thermal plasma) can be generated at relatively high pressures close to normal pressure due to the very high excitation frequency of 2.45 GHz, for example, and the associated high field densities the microwave power, for example at max. 6 kW.
- a non-equilibrium plasma non-thermal plasma
- the microwave power for example at max. 6 kW.
- the non-equilibrium plasma is understood to mean that a number of highly reactive or high-energy particles exist without the average temperature of the exhaust gas being excessively high. In this way, undesirable reactions, e.g. the formation of nitrogen oxides, reduced.
- a pH electrode is provided in the liquid circuit after the liquid jet pump, which is connected to a controller which controls a metering pump for metering in alkali or acid into the liquid circuit. It is therefore advantageous to add a basic sorbent if, for example, acid gases (HF, HCl) are to be washed out.
- a further embodiment of the invention is characterized in that the liquid jet pump and the liquid circuit are connected to a storage vessel for the sorption liquid and that a suction line is connected to the storage vessel and is equipped with a suction for the cleaned exhaust gas is connected.
- At least one aerosol filter is arranged in the suction line, which retains solid and / or liquid aerosols from the exhaust gas.
- the exhaust gas purification system consists of a vertically arranged reaction chamber 1, which is connected at its upper end to a plasma source 2.
- This plasma source 2 is arranged such that excited particles from the plasma source can be coupled into the reaction space.
- a plasma source 2 can be considered as a plasma source, which operates at a frequency of 2.45 GHz and is designed for a power of up to 6 kW.
- the reaction chamber 1 also has at its upper end one or more entrances 4 for the gases or vapors to be disposed of, e.g. Process exhaust gases from processes in semiconductor manufacturing, and one or more side inputs 5 for additional gas. Oxygen and / or hydrogen or water vapor can be considered as additional gases. If the gases or vapors and the additional gas are to be fed directly into the plasma source, this must also be provided with one or more inputs 4 'for the gases or vapors and one or more inputs 5' for additional gas.
- the lower end of the reaction chamber 1 is provided with an outlet 17 which is connected to the suction opening 21 of a liquid jet pump 3.
- the liquid jet pump 3 is part of a liquid circuit in which a circuit pump 6 is arranged.
- the circulation pump 6 is preferably designed as a membrane pump operated by compressed air, which acts as a sorbent for the liquid, solid or soluble Chen components of the exhaust gas used liquid sucks from a storage vessel 7 and promotes the liquid jet pump 3.
- the liquid jet pump 3 has the function of generating a negative pressure of a few 10 mbar in the reaction space 1 and in the plasma source 2 for igniting the plasma and maintaining a negative pressure during the treatment of the exhaust gas, and also the task of treating the exhaust gas treated in the plasma to promote from the reaction chamber 1.
- the size of the negative pressure generated by the liquid jet pump 3 depends on the one hand on the size of the pump and on the other hand on the amount of gases fed in, the amount of liquid delivered and the temperature of the liquid (vapor pressure). For this reason, it is expedient to provide cooling of the liquid or the sorbent in the liquid circuit.
- the storage vessel 7 can be provided with a cooling device 20.
- the pressure in the reaction chamber 1 is measured by a pressure sensor 8, the electrical signal of which controls the circuit pump 6 via a controller 9 so that the pressure in the reaction chamber is regulated to an optimal value.
- a second way of regulating the pressure is to couple the regulator 9 to a throttle valve 19 and to regulate the pressure to optimum values by means of the amount of secondary air drawn in.
- the sorbent has intensive contact with the exhaust gas which has already passed through the plasma, removes solid and soluble constituents from the exhaust gas and flows back from the liquid jet pump 3 into the storage vessel 7.
- a pH electrode 10 which measures the pH of the sorption liquid flowing past and controls a metering pump 12 via a regulator 11, with the aid of which alkali or acid can be metered into the liquid circuit in order to keep the pH at a predetermined value keep stant.
- the exhaust gas converted in the plasma in the reaction chamber 1 and treated with the sorbent in the liquid jet pump 3 leaves the storage vessel 7 via a suction line 13 which is connected to a suction device (not shown).
- Aerosol filters 14 which retain solid and / or liquid aerosols, are accommodated in the suction line 13. These aerosol filters 14 can be cleaned continuously or discontinuously by feeding water and / or sorbents through one or more spray nozzles 15. This water or sorbent flows back into the preliminary reservoir 7, so that the amount of sorbent in the liquid circuit is continuously increased.
- the used sorbent is sucked off together with solid components by means of a pump 16 at the bottom of the storage vessel 7.
- Liquid jet pump 4 'inlet for gases or vapors, 5' inlet for additional gas
