Description

本発明は、植物工場や作物栽培ハウス等の作物生産用施設に燃焼炉からの燃焼排ガスを供給して、燃焼排ガスに含まれる二酸化炭素を作物に施用することにより、作物の収率及び品質の向上を可能とするとともに、燃焼排ガスの燃焼熱を回収し、作物生産用施設に熱供給する作物生産用施設への二酸化炭素含有ガスと熱の供給装置及び供給方法に関する。   The present invention supplies crop flue gas from a combustion furnace to a plant production facility such as a plant factory or a crop cultivation house, and applies carbon dioxide contained in the flue gas to the crop, thereby improving the yield and quality of the crop. The present invention relates to an apparatus and a method for supplying carbon dioxide-containing gas and heat to a crop production facility that enables improvement, collects combustion heat of combustion exhaust gas, and supplies the heat to the crop production facility.

植物工場や作物栽培ハウス等の作物生産用施設では、温度管理のため重油や灯油を燃焼させて得た熱を温水や温風として供給している。また、作物の光合成を促進し、作物の生育促進、収率及び品質の向上のため、作物生産用施設内の二酸化炭素濃度を高める二酸化炭素施用技術があり、重油や灯油を燃焼させた燃焼排ガス中の二酸化炭素を作物生産用施設内に供給し、光合成を促進するようにしている。   In plant production facilities such as plant factories and crop cultivation houses, heat obtained by burning heavy oil or kerosene is supplied as hot water or hot air for temperature control. In addition, there is a carbon dioxide application technology that promotes photosynthesis of crops, promotes crop growth, improves yield and quality, and increases the concentration of carbon dioxide in the plant production facility, and burns exhaust gas that burns heavy oil and kerosene. Carbon dioxide in the plant is supplied to the plant production facility to promote photosynthesis.

例えば特許文献１には、作物生産用施設を温度管理し、また作物生産用施設に肥料としての二酸化炭素を供給するために、重油や灯油の燃焼によって得られた熱を温風として作物生産用施設に供給するとともに、燃焼排ガス中の二酸化炭素をタンクに貯留し、タンクに貯留した二酸化炭素を作物生産用施設に供給する二酸化炭素供給システムが開示されている。ボイラの燃焼排ガスには、作物の成長に悪影響を及ぼす硫黄酸化物及び窒素酸化物が含まれる。このため、特許文献１に記載の二酸化炭素供給システムでは、燃焼排ガスを水溜中にバブリングさせ、硫黄酸化物を除去し、高活性炭素繊維による触媒機能により窒素酸化物を除去している（段落００１３〜段落００１５参照）。   For example, in Patent Document 1, the temperature of a crop production facility is controlled, and the heat obtained by burning heavy oil or kerosene is used as warm air for crop production in order to supply carbon dioxide as a fertilizer to the crop production facility. A carbon dioxide supply system that supplies carbon dioxide in combustion exhaust gas in a tank and supplies the carbon dioxide stored in the tank to a crop production facility is disclosed. Boiler flue gas contains sulfur oxides and nitrogen oxides that adversely affect crop growth. For this reason, in the carbon dioxide supply system described in Patent Document 1, combustion exhaust gas is bubbled into a water reservoir, sulfur oxides are removed, and nitrogen oxides are removed by a catalytic function of highly active carbon fibers (paragraph 0013). To paragraph 0015).

他方、二酸化炭素の排出抑制による温暖化防止、資源の有効利用、廃棄物の減量化を目的として、バイオマスの利活用が要望されている。バイオマスを燃料として使用することができれば、化石燃料の燃焼により排出される二酸化炭素をなくすことができるので、さらなる温暖化防止対策につながる。   On the other hand, there is a demand for the utilization of biomass for the purpose of preventing global warming by suppressing carbon dioxide emissions, effectively using resources, and reducing waste. If biomass can be used as fuel, carbon dioxide emitted by the combustion of fossil fuels can be eliminated, leading to further measures for preventing global warming.

特許文献２には、木質系バイオマスを炭化ガス化処理し、分解ガスを燃焼することによって得られた熱を利用して発電するとともに、分解ガスを燃焼することによって得られた二酸化炭素含有ガスを作物生産用施設に供給し、作物の成長を促進する二酸化炭素供給システムが開示されている（段落００１９〜段落００２３参照）。   Patent Document 2 discloses carbon dioxide-containing gas obtained by carbonizing woody biomass and generating power using heat obtained by burning cracked gas, and by burning cracked gas. A carbon dioxide supply system that supplies a crop production facility and promotes the growth of the crop is disclosed (see paragraphs 0019 to 0023).

特許文献３には、バイオマスを立型炉で燃焼し、バイオマスを燃焼することによって得られた熱を作物生産用施設に供給するとともに、バイオマスを燃焼することによって得られた二酸化炭素含有ガスを作物生産用施設に供給する二酸化炭素供給システムが開示されている。バイオマスを燃料として燃焼させた燃焼排ガスには、作物の成長に悪影響を与える硫黄酸化物、窒素酸化物が含まれる。特許文献３に記載の二酸化炭素供給システムでは、燃焼排ガス中の硫黄酸化物、窒素酸化物などの有害成分をスクラバーで予備的に洗い落とし、さらに多孔質吸着剤により吸着除去する燃焼排ガス処理を行い、処理済み燃焼排ガスを作物生産用施設へ供給している（段落００４１〜段落００４４参照）。   In Patent Document 3, biomass is burned in a vertical furnace, heat obtained by burning the biomass is supplied to a plant production facility, and carbon dioxide-containing gas obtained by burning the biomass is added to the crop. A carbon dioxide supply system for supplying to a production facility is disclosed. Combustion exhaust gas obtained by burning biomass as fuel contains sulfur oxides and nitrogen oxides that adversely affect crop growth. In the carbon dioxide supply system described in Patent Document 3, scrubbers are used to preliminarily wash away harmful components such as sulfur oxides and nitrogen oxides in the combustion exhaust gas, and further, the exhaust gas treatment is performed by adsorption and removal using a porous adsorbent. Treated flue gas is supplied to the plant production facility (see paragraphs 0041-0044).

しかし、バイオマスの燃焼排ガスには、硫黄酸化物、窒素酸化物だけでなく、作物の成長に有害なエチレン、作物生産用施設内の作業者に有害な一酸化炭素が含まれる。エチレンは、蕾の脱落や葉や花の生育不良を招いたり、作物が熟すのを促進するため収穫時の作物が熟しすぎて出荷できないという事態を招く。また、一酸化炭素は、作物生産用施設内で働く作業者の中毒を招く。二次燃焼室を備える大規模な焼却炉では、一酸化炭素を十分に除去できるが、小規模の焼却炉では、二次燃焼室を備えないことが多く、一酸化炭素の除去が課題である。   However, biomass combustion exhaust gas contains not only sulfur oxides and nitrogen oxides, but also ethylene that is harmful to the growth of crops and carbon monoxide that is harmful to workers in facilities for producing crops. Ethylene leads to the loss of strawberries, poor growth of leaves and flowers, and the situation that crops at harvest are too ripe to be shipped because they promote the ripening of the crops. Carbon monoxide also causes addiction to workers working in crop production facilities. A large-scale incinerator with a secondary combustion chamber can sufficiently remove carbon monoxide, but small-scale incinerators often do not have a secondary combustion chamber, and removal of carbon monoxide is a problem. .

本発明は、以上のような事情に鑑みてなされたものであって、燃料を燃焼した燃焼排ガス中の作物に有害な硫黄酸化物、窒素酸化物、一酸化炭素及びエチレンを除去し、浄化した排ガスを作物生産用施設に植物成長を促進する二酸化炭素含有ガスとして供給することができる作物生産用施設への二酸化炭素含有ガスと熱を供給する供給装置及び供給方法を提供することを目的とするものである。   The present invention has been made in view of the circumstances as described above, and removes and purifies sulfur oxides, nitrogen oxides, carbon monoxide, and ethylene harmful to crops in combustion exhaust gas from burning fuel.

燃焼炉１は、バイオマスの供給を受け、バイオマスを燃焼して排ガスを排出する。バイオマスには、木質系バイオマス（例えば木質チップ、木屑、間伐材、製材廃材、建築廃材等）が用いられる。典型的な燃焼炉１は、火格子式燃焼炉であり、火格子を有する燃焼室と、火格子上にバイオマスを供給するための供給口と、燃焼室に燃焼空気を供給する送風機と、を備える。火格子上のバイオマスに燃焼空気を供給して燃焼する火格子式燃焼炉は、燃焼効率が高く好ましいが、炉形式はこれに限定されるものではない。 (Combustion furnace)
The combustion furnace 1 receives supply of biomass, burns the biomass, and discharges exhaust gas. For biomass, woody biomass (for example, wood chips, wood chips, thinned wood, sawmill waste, building waste, etc.) is used. A typical combustion furnace 1 is a grate-type combustion furnace, and includes a combustion chamber having a grate, a supply port for supplying biomass on the grate, and a blower for supplying combustion air to the combustion chamber. Prepare. A grate-type combustion furnace that burns by supplying combustion air to biomass on the grate has high combustion efficiency, but the furnace type is not limited to this.

（熱交換器）
熱交換器２は、燃焼炉１の燃焼排ガス（以下、単に排ガスという）と水との熱交換により水を加熱して温水を得て、暖房、温度管理のための熱を作物生産用施設１１に供給する。熱交換器２と作物生産用施設１１とは、温水配管１２で接続され温水が供給される。熱交換器２で得られた温水を別に設ける蓄熱槽に貯留することにより、作物生産用施設１１の熱需要により効果的に対応して熱を供給することができる。例えば、昼間に得られ貯留された温水（蓄熱された温熱）を、熱需要の大きい夜間に使用するようにするなど、柔軟な対応が可能となる。 (Heat exchanger)
The heat exchanger 2 heats water by heat exchange between combustion exhaust gas (hereinafter simply referred to as exhaust gas) of the combustion furnace 1 and water to obtain hot water, and uses heat for heating and temperature management for the plant production facility 11. To supply. The heat exchanger 2 and the crop production facility 11 are connected by a hot water pipe 12 and supplied with hot water. By storing the hot water obtained by the heat exchanger 2 in a separate heat storage tank, heat can be supplied more effectively in response to the heat demand of the crop production facility 11. For example, it is possible to respond flexibly, for example, by using hot water obtained and stored in the daytime (heated stored heat) at night when heat demand is high.

熱交換器２は、排ガスと水との熱交換により水蒸気を得て、水蒸気を作物生産用施設１１へ供給してもよいし、水蒸気を蒸気タービンに送り、蒸気タービンにより発電し、電気エネルギーを作物生産用施設１１へ供給してもよい。また、燃焼炉１と熱交換器２とを一体化した燃焼ボイラを用いてもよいし、燃焼炉１と熱交換器２が別体のものを用いてもよい。   The heat exchanger 2 may obtain water vapor by heat exchange between the exhaust gas and water, and supply the water vapor to the crop production facility 11.

The dust collector 4 collects dust contained in the exhaust gas, and collects reaction product particles of sodium bicarbonate powder and sulfur oxide (SO x ). It is preferable to use a filtration type dust collector such as a bag filter because the efficiency of collecting the reaction product particles of dust and sulfur oxide is high. Unreacted baking soda powder adhering to the filter surface of the bag filter may also react with sulfur oxides.

（窒素酸化物除去装置）
窒素酸化物除去装置５は、集塵装置４で粉塵が除去された排ガスにアンモニアガスを吹き込むアンモニア供給装置６と、脱硝触媒を収容した脱硝触媒装置７と、を備える。脱硝触媒装置７は、窒素酸化物（ＮＯｘ）をアンモニアとの反応によりＮ２とＨ２Ｏとに分解し窒素酸化物を除去する。アンモニア（ＮＨ3）と窒素酸化物（ＮＯｘ）との反応式は、式２のとおりである。

The carbon monoxide and ethylene removing device 8 introduces the exhaust gas from which nitrogen oxide has been removed by the nitrogen oxide removing device 5 into an oxidation catalyst device containing an oxidation catalyst, and oxidizes carbon monoxide and ethylene by the action of the catalyst. However, it is made a substance such as CO 2 and H 2 O which is harmless to crops or workers. The oxygen used for oxidation is oxygen contained in the exhaust gas. Since combustion air is blown into the combustion furnace 1, there is sufficient oxygen in the exhaust gas. The oxidation catalyst is not limited, but it is preferable to use a catalyst in which platinum or rhodium is supported on a carrier. The temperature at which carbon monoxide and ethylene are oxidized and removed by an oxidation catalyst is not particularly limited, but it is necessary to reheat to operate at a temperature range of 170 to 200 ° C., which is a temperature at which sulfur oxide is removed.

図２は、排ガスに含まれる有害物の濃度を抑制するための制御系統を付加した供給装置の構成図を示す。燃焼炉１、熱交換器２、硫黄酸化物除去装置３、集塵装置４、窒素酸化物除去装置５、一酸化炭素及びエチレン除去装置８、及び浄化ガス供給装置９の構成は、図１に示すものと同一であるので、同一の符号を附してその説明を省略する。   FIG. 2 shows a configuration diagram of a supply apparatus to which a control system for suppressing the concentration of harmful substances contained in the exhaust gas is added. The configuration of the combustion furnace 1, the heat exchanger 2, the sulfur oxide removing device 3, the dust collecting device 4, the nitrogen oxide removing device 5, the carbon monoxide and ethylene removing device 8, and the purified gas supply device 9 is shown in FIG. Since they are the same as those shown, the same reference numerals are given and the description thereof is omitted.

一酸化炭素及びエチレン除去装置８の下流側には、浄化ガスの成分濃度を測定するガス成分濃度計２１が配置される。制御装置２２は、ガス成分濃度計２１の硫黄酸化物の測定値に基づいて、硫黄酸化物除去装置３の重曹供給量を制御する。例えば、制御装置２２は、ガス成分濃度計２１の硫黄酸化物の測定値が所定の許容範囲値よりも高い場合には、重曹供給量を増大させ、低い場合には、重曹供給量を減少させる。   A gas component concentration meter 21 for measuring the component concentration of the purified gas is disposed downstream of the carbon monoxide and ethylene removal device 8. The control device 22 controls the baking soda supply amount of the sulfur oxide removing device 3 based on the measured value of the sulfur oxide of the gas component concentration meter 21. For example, the control device 22 increases the sodium bicarbonate supply amount when the measured value of the sulfur oxide of the gas component concentration meter 21 is higher than a predetermined allowable range value, and decreases the sodium bicarbonate supply amount when the measurement value is low. .

制御装置２２は、ガス成分濃度計２１の窒素酸化物の測定値に基づいて、窒素酸化物除去装置５のアンモニアガス供給量を制御する。例えば、制御装置２２は、ガス成分濃度計２１の窒素酸化物の測定値が所定の許容範囲値よりも高い場合には、アンモニアガス供給量を増大させ、低い場合には、アンモニアガス供給量を減少させる。   The control device 22 controls the ammonia gas supply amount of the nitrogen oxide removing device 5 based on the measured value of the nitrogen oxide of the gas component concentration meter 21. For example, the control device 22 increases the ammonia gas supply amount when the measured value of the nitrogen oxide of the gas component concentration meter 21 is higher than a predetermined allowable range value, and increases the ammonia gas supply amount when the measured value is low. Decrease.

一酸化炭素及びエチレン除去装置８から排出された浄化ガスを熱交換器１０に送るダクトには、分岐して浄化ガスの一部を一酸化炭素及びエチレン除去装置８の上流側に戻す循環流路２３が設けられ、戻す循環ガス量を調整する調整弁２４が配置される。浄化ガスの一部を一酸化炭素及びエチレン除去装置８の上流側に戻すことにより、浄化ガスに残存する一酸化炭素及びエチレンを再度酸化触媒と接触させ、一酸化炭素とエチレンをより低濃度にまで除去する。制御装置２２は、ガス成分濃度計２１の一酸化炭素及びエチレンの測定値に基づいて、調整弁２４の開度を調整し循環ガス量を制御する。例えば、制御装置２２は、ガス成分濃度計２１の一酸化炭素及びエチレン除去装置８の測定値が一定時間以上にわたって所定の閾値以上の場合には、循環ガス量を増大させる。また、制御装置２２は、ガス成分濃度計２１の一酸化炭素及びエチレンの測定値に基づいて、一酸化炭素及びエチレン除去装置８の酸化触媒の交換時期を判定する。例えば、制御装置２２は、ガス成分濃度計２１の一酸化炭素及びエチレン除去装置８の測定値が一定時間以上にわたって所定の閾値以上の場合には、酸化触媒の交換を促す警報を表示する。   In the duct for sending the purified gas discharged from the carbon monoxide and ethylene removing device 8 to the heat exchanger 10, a circulation flow path is branched to return a part of the purified gas to the upstream side of the carbon monoxide and ethylene removing device 8. 23 and an adjustment valve 24 for adjusting the amount of circulating gas to be returned is arranged. By returning a part of the purified gas to the upstream side of the carbon monoxide and ethylene removing device 8, the carbon monoxide and ethylene remaining in the purified gas are brought into contact with the oxidation catalyst again, so that the concentration of carbon monoxide and ethylene is lowered. Remove until. The controller 22 controls the amount of circulating gas by adjusting the opening of the regulating valve 24 based on the measured values of carbon monoxide and ethylene of the gas component concentration meter 21. For example, the control device 22 increases the amount of circulating gas when the measured values of the carbon monoxide and ethylene removal device 8 of the gas component concentration meter 21 are equal to or greater than a predetermined threshold for a certain time or longer. Further, the control device 22 determines the replacement timing of the oxidation catalyst of the carbon monoxide and ethylene removal device 8 based on the measured values of carbon monoxide and ethylene of the gas component concentration meter 21. For example, when the measured values of the carbon monoxide and ethylene removal device 8 of the gas component concentration meter 21 are equal to or greater than a predetermined threshold for a certain time or longer, the control device 22 displays an alarm for prompting replacement of the oxidation catalyst.

図２に示す制御系統を付加した供給装置では、一酸化炭素及びエチレン除去装置８の下流側に、浄化ガスの成分濃度を測定するガス成分濃度計２１が配置され、制御装置２２により制御することとしているが、作物生産用施設１１内の各種ガス成分濃度を測定するガス成分濃度計２１を配置して計測し制御するようにしてもよい。すなわち、作物生産用施設１１内の各種ガス成分濃度の測定値に基づき、硫黄酸化物除去装置３の重曹供給量、窒素酸化物除去装置５のアンモニアガス供給量、浄化ガスの一部を一酸化炭素及びエチレン除去装置８の上流側に戻す循環ガス量を制御して、作物生産用施設１１の操業状況に応じて、供給装置のガス浄化機器を制御することも可能である。   In the supply device to which the control system shown in FIG. 2 is added, a gas component concentration meter 21 for measuring the component concentration of the purified gas is disposed downstream of the carbon monoxide and ethylene removal device 8 and is controlled by the control device 22. However, a gas component concentration meter 21 for measuring various gas component concentrations in the crop production facility 11 may be arranged and measured and controlled. That is, based on the measured values of various gas component concentrations in the plant production facility 11, the amount of sodium bicarbonate supplied from the sulfur oxide removing device 3, the amount of ammonia gas supplied from the nitrogen oxide removing device 5, and a part of the purified gas are oxidized. It is also possible to control the amount of circulating gas returned to the upstream side of the carbon and ethylene removing device 8 and to control the gas purification device of the supply device according to the operation status of the crop production facility 11.

図３は、本発明の第二の実施形態の二酸化炭素含有ガスと熱の供給装置（以下、単に供給装置という）の模式図である。燃焼炉１、熱交換器２、硫黄酸化物除去装置３、集塵装置４、窒素酸化物除去装置５、一酸化炭素及びエチレン除去装置８、浄化ガス供給装置９の構成は、図１に示すものと同一であるので、同一の符号を附してその説明を省略する。   FIG. 3 is a schematic view of a carbon dioxide-containing gas and heat supply device (hereinafter simply referred to as a supply device) according to the second embodiment of the present invention. The configuration of the combustion furnace 1, the heat exchanger 2, the sulfur oxide removing device 3, the dust collecting device 4, the nitrogen oxide removing device 5, the carbon monoxide and ethylene removing device 8, and the purified gas supply device 9 is shown in FIG. Since they are the same as those in FIG.

第二の実施形態の供給装置では、脱硝触媒装置７の脱硝触媒、並びに一酸化炭素及びエチレン除去装置８の酸化触媒に付着したタールミストを除去して、触媒活性を回復させる触媒活性回復手段を付加している点が、第一の実施形態の供給装置と異なる。この触媒活性回復手段は、循環流路３１と、ガス加熱装置３２と、を備える。   In the supply device of the second embodiment, there is provided catalyst activity recovery means for recovering catalyst activity by removing tar mist adhering to the denitration catalyst of the denitration catalyst device 7 and the oxidation catalyst of the carbon monoxide and ethylene removal device 8. The added point is different from the supply device of the first embodiment. This catalytic activity recovery means includes a circulation flow path 31 and a gas heating device 32.

触媒活性回復手段を付加する理由は以下のとおりである。燃焼炉１でのバイオマス燃焼によって発生するタールのほとんどは集塵装置４により除去されるものの、排ガスが集塵装置４から脱硝触媒装置７、一酸化炭素及びエチレン除去装置８に流通するにつれて、排ガス温度がガス状タールの露点以下に低下し、ガス状タールが液化して微量のタールミストが発生する。このタールミストが脱硝触媒装置７の脱硝触媒、並びに一酸化炭素及びエチレン除去装置８の酸化触媒に付着すると、これらの触媒活性が低下する。   The reason for adding the catalyst activity recovery means is as follows. Although most of the tar generated by biomass combustion in the combustion furnace 1 is removed by the dust collector 4, as the exhaust gas flows from the dust collector 4 to the denitration catalyst device 7, the carbon monoxide and ethylene removal device 8, the exhaust gas The temperature falls below the dew point of the gaseous tar, and the gaseous tar is liquefied to generate a small amount of tar mist. When this tar mist adheres to the denitration catalyst of the denitration catalyst device 7 and the oxidation catalyst of the carbon monoxide and ethylene removal device 8, their catalytic activity decreases.

触媒に付着したタールミストを除去する方法として、触媒を触媒装置から取り外し、触媒を加熱炉で空焼きすることによってタールを除去することが知られている。しかし、触媒装置から触媒を出し入れするのは煩雑であり、さらに触媒装置を一定期間停止する必要があることから望ましい除去方法とはいえない。   As a method for removing tar mist adhering to the catalyst, it is known to remove the catalyst by removing the catalyst from the catalyst device and emptying the catalyst in a heating furnace. However, it is cumbersome to put the catalyst in and out of the catalyst device, and further, it is necessary to stop the catalyst device for a certain period, so that it is not a desirable removal method.

一方、発明者は、上記のように発生する微量のタールミストの形態を詳しく調べた結果、触媒に付着しても比較的除去しやすい形態であることを見出した。そこで、発明者は、触媒を触媒装置から取り外す必要がない触媒活性回復手段を創案した。すなわち、本実施形態においては、一酸化炭素及びエチレン除去装置８から排出された浄化ガスの一部をガス加熱装置３２によって加熱し、脱硝触媒装置７の上流側、並びに一酸化炭素及びエチレン除去装置８の上流側に戻し、脱硝触媒装置７の脱硝触媒、並びに一酸化炭素及びエチレン除去装置８の酸化触媒を加熱する。これにより、脱硝触媒及び酸化触媒に付着したタールミストを揮発・除去し、これらの触媒活性を回復させる。   On the other hand, as a result of detailed examination of the form of the trace amount of tar mist generated as described above, the inventor has found that the form is relatively easy to remove even if it adheres to the catalyst. Therefore, the inventor has devised a catalyst activity recovery means that does not require removal of the catalyst from the catalyst device. That is, in the present embodiment, a part of the purified gas discharged from the carbon monoxide and ethylene removal device 8 is heated by the gas heating device 32, and the upstream side of the denitration catalyst device 7, as well as the carbon monoxide and ethylene removal device. 8, the denitration catalyst of the denitration catalyst device 7 and the oxidation catalyst of the carbon monoxide and ethylene removal device 8 are heated. Thereby, the tar mist adhering to the denitration catalyst and the oxidation catalyst is volatilized and removed, and the catalytic activity is recovered.

具体的には、一酸化炭素及びエチレン除去装置８から排出された浄化ガスを熱交換器１０に送るダクトを分岐して、浄化ガスの一部を脱硝触媒装置７の上流側、並びに一酸化炭素及びエチレン除去装置８の上流側に戻す循環流路３１を設ける。そして、循環流路３１に浄化ガスの一部（以下、循環ガスという）を加熱するガス加熱装置３２を配設する。ガス加熱装置３２により加熱された循環ガスにより、脱硝触媒装置７の脱硝触媒、並びに一酸化炭素及びエチレン除去装置８の酸化触媒を加熱し、これにより、脱硝触媒及び酸化触媒に付着したタールミストを揮発・除去する。   Specifically, a duct for sending the purified gas discharged from the carbon monoxide and ethylene removing device 8 to the heat exchanger 10 is branched, and a part of the purified gas is separated from the upstream side of the denitration catalyst device 7 and the carbon monoxide. And the circulation flow path 31 which returns to the upstream of the ethylene removal apparatus 8 is provided. A gas heating device 32 for heating a part of the purified gas (hereinafter referred to as “circulation gas”) is disposed in the circulation flow path 31. The denitration catalyst of the denitration catalyst device 7 and the oxidation catalyst of the carbon monoxide and ethylene removal device 8 are heated by the circulating gas heated by the gas heating device 32, whereby the tar mist adhering to the denitration catalyst and the oxidation catalyst is removed. Volatilize and remove.

ガス加熱装置３２としては、電気ヒーター式ガス加熱装置が好ましい。ガス加熱装置として電気ヒーター式ガス加熱装置を用いる場合には、触媒から揮発して循環ガスに含まれるタールを燃焼するために反応用空気を必要に応じて供給し、タールを燃焼する。   As the gas heating device 32, an electric heater type gas heating device is preferable. When an electric heater type gas heating device is used as the gas heating device, reaction air is supplied as necessary to burn the tar contained in the circulating gas by volatilizing from the catalyst, and the tar is burned.

脱硝触媒及び酸化触媒を昇温する温度は、１６０〜５００℃の温度範囲とすることが好ましく、１８０〜３００℃の温度範囲とすることがさらに好ましい。付着したタールミストを揮発・除去するために、脱硝触媒及び酸化触媒の温度を、集塵装置４の運転温度以上であって、タールミストの露点より高い温度にする必要があるからである。   The temperature for raising the temperature of the denitration catalyst and the oxidation catalyst is preferably in the temperature range of 160 to 500 ° C, more preferably in the temperature range of 180 to 300 ° C. This is because in order to volatilize and remove the attached tar mist, the temperature of the denitration catalyst and the oxidation catalyst must be higher than the operating temperature of the dust collector 4 and higher than the dew point of the tar mist.

脱硝触媒及び／又は酸化触媒の触媒活性の低下が認められた場合に、加熱した循環ガスを戻す運転を行い、触媒活性を回復させる操作を行う。本実施形態によれば、脱硝触媒装置７並びに一酸化炭素及びエチレン除去装置８の運転中でも、各装置を停止させることなく触媒活性回復操作を行うことができる。もちろん各装置の停止中でも触媒活性回復操作を行うことができる。   When the catalytic activity of the denitration catalyst and / or the oxidation catalyst is reduced, an operation of returning the heated circulating gas is performed to recover the catalytic activity. According to this embodiment, even during the operation of the denitration catalyst device 7 and the carbon monoxide and ethylene removal device 8, the catalyst activity recovery operation can be performed without stopping each device. Of course, the catalyst activity recovery operation can be performed even when each apparatus is stopped.
