Definitions
- the invention relates to a method and a system for purifying exhaust gases with a regenerative afterburner.
- the afterburner system has at least two regenerators filled with heat storage bodies, which heat alternately at least one of the regenerators, in the combustion chamber the carbon compounds are oxidized at a temperature of more than 850 ° and the hot clean gas formed by the other Regenerator is removed.
- the sequence of flow through the two regenerators is reversed to allow continuous operation with the absorption and release of the heat energy of the exhaust gas. Through this process, heat recovery efficiencies of more than 90% are achieved.
- the invention is therefore based on the object to improve the method and the system for purifying exhaust gases with a regenerative afterburner so that operating problems of the post-combustion system are reduced and the service life of the system is increased.
- the exhaust gases to be cleaned before being fed to the regenerative afterburner in at least one preheating to temperatures between 100 ° C and 250 ° C, preferably between 100 ° C and 200 ° C and most preferably between 120 ° C and 150 ° C, preheated.
- the plant according to the invention for carrying out the above method provides, in addition to a regenerative afterburner, at least one upstream preheating stage in which the exhaust gases to be cleaned are preheated to the above temperatures.
- the exhaust gases to be cleaned are, in particular, exhaust gas from the cement and mineral industries.
- the regenerative afterburning system preferably comprises at least a first and a second heat storage and an oxidation zone arranged therebetween, wherein the exhaust gas preheated in the at least one preheating stage is alternately further heated in at least one of the heat accumulators, harmful components contained in the exhaust gas, such as hydrocarbon compounds, in the oxidation zone. oxidize and the resulting, purified exhaust gas is withdrawn through the at least one other heat storage.
- the heating of the exhaust gas to be cleaned or a mixture of different gas streams can take place in the preheating, for example, by at least one indirect heat exchanger, wherein the heat is transferred in the heat exchanger, for example by means of a hot gas stream with or without a heat transfer medium, such as thermal oil, or by means of heat pipes.
- the hot gas stream may in particular be the purified exhaust gas from the regenerative post-combustion plant.
- preheater exhaust gas and / or cooling gas of a cement production process as hot gas in whole or in part.
- the preheating stage as a combustion chamber and / or to provide a burner for heating the exhaust gas to be cleaned.
- the amount of fuel supplied via the burner or the combustion chamber can be so be measured that in the regenerative incinerator no further or a correspondingly reduced amount of fuel must be supplied.
- the at least one first and / or second heat storage for the reduction of nitrogen oxides and / or oxidation of the hydrocarbons may be at least partially equipped with catalytically active material.
- Fig. 1 shows a plant for the purification of exhaust gases with a regenerative
- Fig. 2 shows a plant for the purification of exhaust gases with a regenerative
- a plant for cement clinker production is shown schematically by the reference numerals 1 to 8.
- cement raw meal 1 is preheated in a preheater 2 operated with the exhaust gases of a rotary kiln 3 and optionally partially calcined before the preheated raw meal is finished in the rotary kiln 3 directly or via a calciner (not shown).
- the fired cement clinker is then cooled in the clinker cooler 4.
- the preheater exhaust gas 5 leaving the preheater 2 is cooled in a heat exchanger 6 from, for example, 400 ° C. to 320 ° C. before it is used in a raw mill 7 for drying raw material.
- the Preheater 5 has after the raw mill 7, a temperature of less than 100 ° C and is dedusted in a subsequent exhaust filter 8.
- the dedusted preheater exhaust gas 5 is optionally mixed with a pre-cleaned bypass exhaust 9 and forms the exhaust gas to be cleaned 10.
- the optional bypass exhaust gas is withdrawn via a branching off in the region of the inlet of the rotary kiln 3 bypass line 1 1, cooled in a bypass quench 12 and in a filter 13th dusted.
- the exhaust gas 10 to be purified is first supplied to a preheating stage 14 before it reaches the regenerative post-combustion plant 15 and leaves the post-combustion plant as purified exhaust gas 16.
- the preheating stage 14 is formed in the illustrated embodiment by a heat exchanger 17 and an adjoining second heat exchanger 18.
- the first heat exchanger 17 is designed as a gas-gas heat exchanger and transfers the heat of the purified exhaust gas 16 to the exhaust gas 10 to be cleaned.
- the second heat exchanger 18 cooperates with the heat exchanger 6, wherein the heat of the preheater exhaust gas 5, for example via a heat transfer medium 19 between the two heat exchangers 6 and 18 is transmitted.
- the exhaust gas 10 to be purified is heated in the preheating stage 14 from a temperature of partially below 100 ° C to temperatures between 100 ° C and 250 ° C, preferably between 100 ° C and 200 ° C and most preferably between 120 ° C and 150 ° C, preheated before it enters the regenerative incinerator 15.
- the regenerative post-combustion plant 15 provides in the illustrated embodiment, a first heat storage 20, a second heat storage 21 and an oxidation zone 22 arranged therebetween, wherein the preheated in the preheating stage 14 exhaust gas 10 is further heated in one of the two heat storage, contained in the oxidation zone 22 in the exhaust gas harmful components, such as hydrocarbon compounds, oxidize and the resulting, purified exhaust gas 16 is withdrawn through the other heat exchanger.
- a burner 23 in particular a natural gas burner, be provided in the oxidation zone.
- At least one of the two heat accumulators can be equipped, inter alia, for the reduction of nitrogen oxides and / or for the oxidation of hydrocarbons, at least partially with catalytically active material.
- means 24 are provided for the injection of an ammonia-containing reducing agent.
- the preheating stage 14 has, instead of the heat exchangers 17 and 18, a combustion chamber 25 which, for example, has a burner 26, in particular a natural gas burner.
- the exhaust gas 10 to be purified which in turn is composed of the dedusted exhaust gas 5 of the preheater 2 and possibly a pre-cleaned bypass gas 9 and optionally another hot gas, is heated up accordingly in the combustion chamber 25.
- the desired temperature is to be such that the dew point of any pollutant components in the first and second heat storage 20, 21 of the regenerative afterburner 15 is not exceeded. If the supplied fuel is not completely oxidized in the upstream combustion chamber 25, it is guided with the exhaust gas into the regenerative after-combustion system 15.
- the heating of the exhaust gas 10 to be cleaned in the preheating stage by means of one or more hot gases is not limited to the embodiment shown in FIG.
- other, available hot gases such as the cooler exhaust air can be used.
- a combination of at least one heat exchanger and a burner or a combustion chamber and the already mentioned mixture and / or separate heating of partial gas flows would be conceivable.
