従来より、集塵装置や集塵ダクトへの結露防止の対策には種々の技術がある。たとえば、一連の集塵設備とは別に熱源としての加熱器と送風ファンにより温風を集塵ダクトから集塵装置に送り込むようにした技術がある(特許文献１参照)。また、一連の集塵設備に使用されている装置から排出される高温ガスを利用するものとして、集塵装置の下流に配置される、排気ガス中の有害揮発成分や悪臭成分を燃焼除去する燃焼酸化装置から出る高温ガスの一部を前記集塵装置の入口にフィードバックさせる技術がある(特許文献２、特許文献３参照)。 Conventionally, there are various techniques for preventing condensation on a dust collector or a dust collection duct. For example, there is a technique in which hot air is sent from a dust collection duct to a dust collector using a heater and a blower fan as a heat source separately from a series of dust collection equipment (see Patent Document 1). Combustion that removes harmful volatile and odorous components in exhaust gas, which is located downstream of the dust collector, using high-temperature gas discharged from the equipment used in a series of dust collectors There is a technique for feeding back a part of the hot gas emitted from the oxidizer to the inlet of the dust collector (see Patent Document 2 and Patent Document 3).
しかしながら、前記特許文献１記載の技術では、集塵設備とは別個に加熱器の熱源を用いるため、該設備費用とは別途燃料使用量や電気料が必要となり、全設備費用が高くなるという問題がある。一方、前記特許文献２、３記載の技術では、集塵系内にガス温度を昇温するための熱源を備える必要がり、コスト高になるという問題がある。 However, in the technique described in Patent Document 1, since the heat source of the heater is used separately from the dust collection equipment, a fuel usage amount and an electric charge are required separately from the equipment cost, and the total equipment cost becomes high. There is. On the other hand, in the techniques described in Patent Documents 2 and 3, there is a problem that it is necessary to provide a heat source for raising the gas temperature in the dust collection system, resulting in an increase in cost.
そこで、本発明は、叙上の事情に鑑み、集塵設備以外の設備から無駄に廃棄される高温ガスの熱量を有効に使用して、集塵装置系内に発生する結露や潮解性を有する粉塵の固結などを防止することができる集塵設備を提供することを目的とする。 Therefore, in view of the above circumstances, the present invention has the dew condensation and deliquescence generated in the dust collector system by effectively using the amount of heat of high-temperature gas that is wasted from facilities other than the dust collection equipment. An object of the present invention is to provide a dust collection facility capable of preventing dust consolidation.
本発明の集塵設備は、送風手段により吸引部から排気ガスを吸引した該排気ガス中の成分を除去する集塵装置を含む集塵設備であって、該集塵設備とは別途稼動している設備の装置から排出される高温ガスの廃熱を前記集塵装置内に導入するように構成されてなることを特徴としている。 The dust collection equipment of the present invention is a dust collection equipment including a dust collection device that removes components in the exhaust gas that has sucked the exhaust gas from the suction section by the blowing means, and operates separately from the dust collection equipment. The waste heat of the high-temperature gas discharged from the equipment of the existing equipment is introduced into the dust collector.
本発明によれば、集塵設備以外の設備から無駄に廃棄される高温ガスの熱量を有効に使用することにより、集塵設備費用を高騰させることがなく、集塵装置系内に発生する結露や潮解性を有する粉塵の固結などを効率良く防止することができる。 According to the present invention, by effectively using the amount of heat of high-temperature gas that is wasted from facilities other than the dust collection equipment, the condensation generated in the dust collector system without increasing the cost of the dust collection equipment. And caking of dust having deliquescence can be efficiently prevented.

As shown in FIG. 1, an embodiment of the present invention is a dust collector system facility (dust collection facility) that includes a dust collection hood 1 that is a suction portion, a dust collection device 2, and a blower 3 that is a blowing means. ) It is configured to introduce the waste heat of the high-temperature gas discharged from the apparatus B of the facility B operating separately to the dust collector 2 of A. In the present invention, the dust collection facility A is not limited to this, and a dust collection facility in which a combustion device for removing harmful components, a decomposition furnace, a denitration device, or the like is disposed downstream of the blower. It can be. The facility B operating separately from the dust collection facility A is not particularly limited as long as it is a facility that is a heat source not included in the dust collection facility. For example, in the case of a foundry, a cupola Examples of the equipment of the equipment B include heat sources such as heat exchangers, ladles, melting furnace heating burners, and the like. In addition, as an apparatus of the installation B in this Embodiment, the heat exchanger B1 of the said cupola installation is used. Moreover, heat sources, such as a boiler installation or a heating furnace installation, can also be mentioned as an example of the apparatus of the other installation B. For example, in the case of this heating furnace facility, the heat source of the heating furnace exhaust gas such as a reflection furnace or a sintering furnace is often released as it is to the atmosphere, which is an effective heat source.
前記集塵フード１と集塵装置２は集塵ダクト４により連結されているとともに、該集塵装置２と前記送風機３は排気ダクト５により連結されている。この集塵装置２は、たとえば、湿潤なガス（たとえば、水分や酸が含まれるガス）や、潮解性のダストが含まれる設備からのダクト６から排出される排気ガスＧ１を前記送風機３により吸引して、前記集塵フード１に集められた排気ガス中の成分である塵埃と空気を分離できる機構であれば、とくに限定されるものではなく、排気ガス中の成分の除去目的に応じて適宜選定することができる。たとえば、パルスジェット式集塵機やサイクロン式集塵機などとすることができる。 The dust collecting hood 1 and the dust collecting device 2 are connected by a dust collecting duct 4, and the dust collecting device 2 and the blower 3 are connected by an exhaust duct 5. For example, the dust collector 2 sucks exhaust gas G1 discharged from a duct 6 from a facility containing wet gas (for example, gas containing moisture or acid) or deliquescent dust by the blower 3. The mechanism is not particularly limited as long as it is a mechanism capable of separating dust and air, which are components in the exhaust gas collected in the dust collection hood 1, and appropriately according to the purpose of removing the components in the exhaust gas. Can be selected. For example, a pulse jet dust collector or a cyclone dust collector can be used.
また、前記キュポラ設備の熱交換器Ｂ１には、前記集塵装置２より上流の所定の位置、たとえば管口７ａが集塵フード１内に向けて配置される熱循環用配管７が連結されている。なお、本発明においては、これに限定されるものではなく管口７ａが前記集塵フード１と集塵ダクト４との接続部に連結することができる。また、前記熱循環用配管７の途中に、高温ガスを送り出すための送風機または高温ガスと排気ガスとの混合割合を調整するためのガス調整バルブなどを設けることもできる。 The heat exchanger B1 of the cupola facility is connected to a heat circulation pipe 7 in which a predetermined position upstream from the dust collector 2, for example, a pipe port 7a is arranged in the dust collection hood 1. Yes. In addition, in this invention, it is not limited to this, The pipe port 7a can be connected with the connection part of the said dust collection hood 1 and the dust collection duct 4. FIG. Further, a blower for sending out the high temperature gas or a gas adjusting valve for adjusting the mixing ratio of the high temperature gas and the exhaust gas can be provided in the middle of the heat circulation pipe 7.
前記キュポラ設備の熱交換器Ｂ１から排出される高温ガスＧ２は、熱循環用配管７を通ったのち、集塵フード１に吸引された排気ガスＧ１と混合され、該排気ガスＧ１の温度を上昇させながら混合ガスＧ３として集塵ダクト４を流通する。ついで、混合ガスＧ３が前記集塵装置２内に導入したのち、粉塵などの塵埃が除去された混合ガスＧ３はさらに排気ダクト５および送風機３の排気口を通って外気に排出される。 The hot gas G2 discharged from the heat exchanger B1 of the cupola facility is mixed with the exhaust gas G1 sucked into the dust collection hood 1 after passing through the heat circulation pipe 7, and the temperature of the exhaust gas G1 is increased. The dust collection duct 4 is circulated as the mixed gas G3. Next, after the mixed gas G3 is introduced into the dust collector 2, the mixed gas G3 from which dust such as dust has been removed is further discharged to the outside air through the exhaust duct 5 and the exhaust port of the blower 3.
本実施の形態では、集塵設備以外のキュポラ設備の熱交換器から排出される高温ガスを集塵装置内に導入することにより、集塵フードから送風機の排気口までの集塵装置系内に発生する結露や、集塵フードから集塵装置内における潮解性粉塵の固結などを防止することができる。また、熱交換器から無駄に廃棄される高温ガスの熱量を有効に使用しているため、集塵設備費用を高騰させることがない。さらに、現在大気解放されている排ガスなどは集塵設備で除塵されるため、大気へのばい塵などの排出量が低減でき、環境負荷低減となる。 In the present embodiment, by introducing the high temperature gas discharged from the heat exchanger of the cupola facility other than the dust collection facility into the dust collection device, the dust collection system from the dust collection hood to the exhaust port of the blower is installed. It is possible to prevent dew condensation that occurs and consolidation of deliquescent dust in the dust collector from the dust collection hood. Moreover, since the amount of heat of the high temperature gas that is wasted from the heat exchanger is effectively used, the cost of the dust collection equipment is not increased. Furthermore, since the exhaust gas currently released to the atmosphere is removed by the dust collection equipment, the amount of dust emission to the atmosphere can be reduced, and the environmental load is reduced.
