Description
本発明は、破砕処理施設において破砕物中の赤熱金属片などによる破砕物の火災が発生した場合の延焼を効率的に防止する方法に関する。 The present invention relates to a method for efficiently preventing the spread of fire when a fire of a crushed material occurs due to a red hot metal piece in the crushed material in a crushing treatment facility.
材質や大きさが様々な都市ごみや産業廃棄物を処理するに当っては、まず、破砕機で所定の大きさに破砕してから、金属/非金属、可燃物/不燃物などに選別し、性状にあわせて処理している。 When disposing of municipal waste and industrial wastes of various materials and sizes, first crush them to a specified size with a crusher and then sort them into metal / nonmetal, combustible / incombustible materials, etc. , Processing according to the properties.
小型ガスボンベ、スプレー缶など、可燃性物質が収納された容器類は、危険物として予め分離されるが、万一破砕機にこれら危険物が投入された場合に備えて、特許文献1では、破砕機内に窒素ガスを導入し、酸素ガス濃度を8〜11%の濃度地に保持して、可燃性ガスが発生しても爆発限界値とならないようにしている。 Containers containing flammable substances, such as small gas cylinders and spray cans, are separated in advance as dangerous materials. However, in the event that these dangerous materials are put into a crusher, in Patent Document 1, crushing is performed. Nitrogen gas is introduced into the machine, and the oxygen gas concentration is maintained at a concentration of 8 to 11% so that the explosion limit value is not reached even if combustible gas is generated.
さらに、金属を含む廃棄物を破砕機で破砕すると、廃棄物中の金属は破砕されるときの摩擦熱により赤熱金属片となる。この赤熱金属片は200℃もの高温となることがあり、このような高温の赤熱金属片に可燃性廃棄物やコンベアベルトが接触すると、これらは次第に加熱されて発火し、火災を発生させる。 Furthermore, when the waste containing metal is crushed with a crusher, the metal in the waste becomes red hot metal pieces due to frictional heat generated when the waste is crushed. This red hot metal piece may be as high as 200 ° C. When the high temperature red hot metal piece comes into contact with combustible waste or a conveyor belt, they are gradually heated to ignite and generate a fire.
このような火災は、破砕機で破砕された破砕物を次工程に移送するコンベア上で生じることが多く、また、前述の爆発が生じた場合、コンベア上の破砕物に引火することも多いので、破砕機からのコンベアには火災及び/又は爆発感知手段を設け、感知手段がコンベア上の破砕物の高温部や破砕物の火炎を検知した場合、破砕機とコンベアを停止させ、コンベア上に散水して冷却又は消火を行なっていた。 Such a fire often occurs on the conveyor that transfers the crushed material crushed by the crusher to the next process, and when the above-mentioned explosion occurs, the crushed material on the conveyor is often ignited. The conveyor from the crusher is provided with fire and / or explosion detection means, and when the detection means detects the high temperature part of the crushed material on the conveyor or the flame of the crushed material, the crusher and the conveyor are stopped and placed on the conveyor. Sprinkling water to cool or extinguish.
しかし、この方法では破砕物の表面の高温部の冷却や燃焼の消火は可能であるが、破砕物の内部の赤熱金属片まで冷却することはできず、一旦消火した後に、再び火災が発生することがあった。
しかも、破砕物の内部の赤熱金属片が原因で発生する火災は、高温部が広範囲に及んでいることが多いので大規模な火災となり易く、さらに、破砕機から破砕物を移送するコンベアは、次工程の選別機などの上部から破砕物を投入するため上向きに設置されているので、フードで覆われたコンベア内は煙突と同じ機能を果たし、一旦火災が発生すると消火が困難となり設備に重大な損傷を与えることが多かった。
However, with this method, it is possible to cool the high temperature part of the surface of the crushed material and extinguish the combustion, but it is not possible to cool down to the red hot metal pieces inside the crushed material. There was a thing.
Moreover, fires caused by red hot metal pieces inside the crushed material tend to be large-scale fires because the high-temperature part often covers a wide area, and further, the conveyor for transferring the crushed material from the crusher is Since it is installed upward to throw crushed material from the top of the next-stage sorter, etc., the conveyor covered with the hood performs the same function as a chimney, and once a fire breaks out, it is difficult to extinguish and is critical to the equipment Often caused serious damage.
このような破砕物の内部の赤熱金属片などが原因で発生する火災を防ぐため、特許文献2では、コンベア部の火災検知信号により、コンベアを逆回転させてコンベア上の破砕物を系外に排出し、そこで散水消火するようにしている。
しかし、この方法では、系外に排出した破砕物を処理するためには、系内に戻すか、別途処理する必要があった。
In order to prevent a fire caused by such a red hot metal piece inside the crushed material, in Patent Document 2, the conveyor is reversely rotated by a fire detection signal of the conveyor portion so that the crushed material on the conveyor is removed from the system. The water is discharged and the water spray is extinguished.
However, in this method, in order to process the crushed material discharged out of the system, it has been necessary to return it to the system or to process it separately.
本発明の課題は、破砕機で生じた爆発、あるいは破砕物の内部の赤熱金属片などが原因で発生する火災およびその延焼を確実に防ぐとともに、消火後の処理が簡単な消火方法および装置を提供することである。 An object of the present invention is to provide a fire extinguishing method and apparatus that reliably prevent a fire caused by an explosion caused by a crusher or a red hot metal piece inside a crushed material and its spread of fire, and that can be easily processed after the fire is extinguished. Is to provide.
上記課題を解決するため、本発明は、廃棄物を破砕機に投入し、破砕された廃棄物をコンベアで移送し、該コンベアの下流からの廃棄物を、シュートを介して次工程に導く廃棄物処理において、コンベアに設けられた火災及び/又は爆発感知手段がコンベア内で火災あるいは爆発を感知した場合、シュートの通路を遮断し、前記コンベア上の廃棄物を該遮断したシュート内に蓄積させ、蓄積した廃棄物に散水して前記シュート内を水で充満させることを特徴とするものである。 In order to solve the above problems, the present invention throws waste into a crusher, transfers the crushed waste by a conveyor, and discards waste from the downstream of the conveyor to the next process through a chute. In material processing, when the fire and / or explosion detection means provided on the conveyor detects a fire or explosion in the conveyor, the passage of the chute is blocked and the waste on the conveyor is accumulated in the blocked chute. The accumulated waste is sprinkled to fill the chute with water.
廃棄物として混在する金属材は、破砕機で破砕されて多数の赤熱金属片となり、他の廃棄物の破砕物中に分散されるので、コンベア上の破砕物の表面に、赤熱金属片による高温部又は赤熱金属片が原因で生じた発火炎が検知された場合、その周辺の破砕物中にも赤熱金属片が混在している可能性が高いが、本発明によれば、このような検知部の周辺の破砕物中に混在する赤熱金属片を含めてシュート内に蓄積し、水を充満させて冷却、消火するので、赤熱金属片を原因とする火災およびその延焼を確実に防止できる。また、破砕機内で爆発が生じた場合にも、可燃物を収容していた容器が金属の場合には、赤熱金属片が端物に混在するが、本発明によれば、このような場合にも、破砕機からの引火による火災だけでなく、赤熱金属片を原因とする火災の発生およびその延焼を確実に防止できる。さらに、このような処理を系内で行うことから、消火後の処理も通常通りに行なえるので簡単である。 Metal materials mixed as waste are crushed by a crusher into a large number of red hot metal pieces and dispersed in other waste crushed pieces. In the case where an ignition flame caused by a part or a red hot metal piece is detected, there is a high possibility that the red hot metal piece is also mixed in the surrounding crushed material. Since the red hot metal pieces mixed in the crushed material around the part are accumulated in the chute and filled with water to cool and extinguish the fire, the fire caused by the red hot metal pieces and the spread of the fire can be reliably prevented. In addition, even when an explosion occurs in the crusher, if the container that contained the combustible material is a metal, red hot metal pieces are mixed in the end piece, but according to the present invention, In addition, it is possible to reliably prevent not only a fire caused by ignition from a crusher but also a fire caused by a red hot metal piece and its spread of fire. Furthermore, since such processing is performed in the system, processing after fire extinguishing can be performed as usual, so that it is easy.
さらに、本発明の方法は、廃棄物を破砕する破砕機、破砕機で破砕された廃棄物を移送するコンベア、及び該コンベア下流からの廃棄物を次工程に導くシュートを備えた廃棄物処理設備において、前記シュートには前記コンベアに設けられた火災及び/又は爆発感知手段からの信号によりシュートの通路を遮断する遮断手段、及び該遮断手段により遮断されたシュート内を水で充満させる散水手段を備えた装置により実施することができる。 Furthermore, the method of the present invention comprises a crusher for crushing waste, a conveyor for transferring waste crushed by the crusher, and a waste treatment facility equipped with a chute for guiding waste from downstream of the conveyor to the next process. The chute is provided with blocking means for blocking the passage of the chute by a signal from a fire and / or explosion detection means provided on the conveyor, and watering means for filling the chute blocked by the blocking means with water. It can be carried out by a device provided.
本発明における火災感知手段としては、破砕機で破砕された廃棄物を移送するコンベアにおいて、火災の原因となるコンベア上の破砕物の高温部や発火炎を検知する感温、感炎検知器が例示でき、爆発感知手段としては、破砕機での爆発を感知する圧力検知器が例示できる。 As a fire detection means in the present invention, in a conveyor for transferring waste crushed by a crusher, there is a temperature detection and a flame detection detector for detecting a high temperature part of a crushed material on the conveyor causing a fire and a flame. As an example of the explosion sensing means, a pressure detector for sensing an explosion in a crusher can be exemplified.
係る火災及び/又は爆発感知手段からの検知信号により破砕機を停止するが、破砕された廃棄物を移送するコンベアは駆動したままとし、該コンベアと次工程を接続するシュートの通路を遮断し、該シュート内にコンベア上の破砕物の全てを蓄積し、破砕物内の赤熱金属片を冷却するため、散水によりシュート内を水で充満させる。 The crusher is stopped by a detection signal from the fire and / or explosion detection means, but the conveyor for transferring the crushed waste is kept driven, and the passage of the chute connecting the conveyor and the next process is shut off, In order to accumulate all of the crushed material on the conveyor in the chute and cool the red hot metal pieces in the crushed material, the chute is filled with water by watering.
したがって、コンベアで移送された破砕物を次工程へ導くシュートおよび該シュートを遮断する遮断手段は、必要な強度と耐水性を備えた部材で構成し、遮断手段で遮断されたシュートの内部には、コンベア上の破砕物の全量が収容可能で、散水される水を充満し得る容器状空間を形成させる必要がある。 Therefore, the chute for guiding the crushed material transferred by the conveyor to the next process and the shut-off means for shutting off the chute are composed of members having the necessary strength and water resistance, and the chute blocked by the shut-off means is inside the chute. It is necessary to form a container-like space that can accommodate the entire amount of crushed material on the conveyor and can be filled with water to be sprinkled.
シュートの遮断手段としては、シュートの底面開口を塞ぐスライド式の防火ダンパが例示されるが、シュート内に上記空間を形成し得るものであれば、手段を問わない。 Examples of the chute blocking means include a slide-type fire damper that closes the bottom opening of the chute, but any means may be used as long as the space can be formed in the chute.
遮断されたシュート内で充満された水により赤熱金属片が冷却された破砕物は、シュート内又は外で固液分離され、次工程で通常通り処理される。 The crushed material, in which the red hot metal pieces are cooled by the water filled in the blocked chute, is solid-liquid separated inside or outside the chute and processed as usual in the next step.
本発明によれば、廃棄物等の破砕施設において、大規模火災の原因となる赤熱金属片を確実に冷却し火災の発生および延焼を防止するとともに、かかる処理を系内で行うので、消火処理後の破砕物の処理も通常通り行うことができる。 According to the present invention, in a crushing facility for waste or the like, a red hot metal piece that causes a large-scale fire is reliably cooled to prevent the occurrence of a fire and the spread of fire, and such a process is performed in the system. The subsequent processing of the crushed material can also be performed as usual.
本発明の実施例を図で説明する。1は、破砕機2に廃棄物などの被破砕物を投入するための投入コンベア、3は、破砕機2で破砕された破砕物を次工程の設備に投入するため高所に移送するための第1のコンベア、6は、第1のコンベアで高所に移送された破砕物を次工程の設備に移送する第2のコンベア、4は、第1のコンベアから落下する破砕物を第2のコンベアの上流側に導くシュート、5は該シュートを閉塞する防火ダンパ、10は、第1コンベアの内部を監視する監視カメラである。
破砕機2で破砕され、第1のコンベア3、第2のコンベア6で移送された破砕物は、磁気選別機7で鉄が分離され、選別設備8で、(破砕)粒度差や比重差により、非鉄金属、プラスチック、木材、紙などに選別される。
Embodiments of the present invention will be described with reference to the drawings. Reference numeral 1 denotes an input conveyor for supplying an object to be crushed, such as waste, into the crusher 2, and 3 denotes a transfer for moving the crushed material crushed by the crusher 2 to a high place in order to input the equipment to the next process. The first conveyor 6 is a second conveyor for transferring the crushed material transferred to a high place by the first conveyor to the next process equipment, and 4 is a second conveyor for crushed material falling from the first conveyor. A chute that leads to the upstream side of the conveyor, 5 is a fire damper that closes the chute, and 10 is a monitoring camera that monitors the inside of the first conveyor.
The crushed material that has been crushed by the crusher 2 and transferred by the first conveyor 3 and the second conveyor 6 is separated from iron by the magnetic sorter 7, and is sorted by the crushing equipment 8 due to particle size differences and specific gravity differences. Sorted into non-ferrous metals, plastics, wood, paper, etc.
第1のコンベア3の適宜の箇所には、散水器11、感熱検出器12、感炎検出器13が設けられ、コンベア3上の破砕物の表面の高温部の存在や発火部の炎を検知すると、破砕機2を停止させ、貯水槽9のポンプを起動し散水器11から散水して破砕物の表面の高温部の冷却や発火部の消火を行うとともに、シュート4を防火ダンパ5で閉塞する。 A sprinkler 11, a heat sensitive detector 12, and a flame sensitive detector 13 are provided at appropriate locations on the first conveyor 3 to detect the presence of a high-temperature portion on the surface of the crushed material on the conveyor 3 and the flame of the ignition portion. Then, the crusher 2 is stopped, the pump of the water storage tank 9 is started and water is sprinkled from the sprinkler 11 to cool the high temperature part of the surface of the crushed material and extinguish the ignition part, and the chute 4 is closed with the fire prevention damper 5. To do.
破砕機は停止するので、破砕機から第1コンベアへの破砕物の排出も途絶えるが、第1のコンベア3の駆動は継続しているので、検出器12,13により高温又は炎が検知されたときに第1のコンベア上に存在した破砕物はすべて、防火ダンパ5により閉塞されたシュート4内に蓄積される。 Since the crusher stops, the discharge of the crushed material from the crusher to the first conveyor is interrupted, but since the driving of the first conveyor 3 continues, high temperature or flame is detected by the detectors 12 and 13. Sometimes, all the crushed material present on the first conveyor is accumulated in the chute 4 closed by the fire damper 5.
シュート4内に蓄積された破砕物が完全に水没するまで散水すれば、破砕物内に混在する赤熱金属片の冷却・消火は確実に行われる。その後、防火ダンパ5を開き、水没した破砕物を水とともに第2コンベアの上流部に落下させる。第2コンベアは、図2に示すように若干上向きに設置し、上流側のベルトの三方を最後尾のスカート16、及び側面のスカート17で覆うようにしておけば、固形の破砕物はコンベアベルト15により上方に移送され、水はスカート16,17とコンベアベルト15の隙間から流出し、排水枡14内に流入するので、破砕物から水分を分離することができる。
If water is sprinkled until the crushed material accumulated in the chute 4 is completely submerged, the red hot metal pieces mixed in the crushed material are reliably cooled and extinguished. Then, the fireproof damper 5 is opened, and the submerged crushed material is dropped together with water onto the upstream portion of the second conveyor. If the second conveyor is installed slightly upward as shown in FIG. 2 and the three sides of the upstream belt are covered with the
水分が分離された破砕物は、通常どおり、次工程の選別施設で選別される。 The crushed material from which water has been separated is sorted in the next-stage sorting facility as usual.
さらに、防火ダンパの開放と同時に粉砕機を起動させることにより、冷却消火によるシステムの休止期間を最小限とすることができる。 Furthermore, by starting the pulverizer simultaneously with the opening of the fireproof damper, it is possible to minimize the system downtime due to cooling and extinguishing.
