な集塵装置における消火方法に関する。[Detailed Description of the Invention] 3. Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a method for extinguishing a fire in a dust collector, and more specifically, the present invention relates to a method for extinguishing a fire in a dust collector, and more specifically, a method for extinguishing a fire in a dust collector, and more specifically, a method for extinguishing a fire in a dust collector, and more specifically, a method for extinguishing a fire in a dust collector, and more specifically, a method for extinguishing a fire in a dust collector, and more specifically, a method for extinguishing a fire in a dust collector, and more specifically, a method for extinguishing a fire in a dust collector. Regarding a fire extinguishing method in a dust collector.
［発明の背景］
最近、木材加工工場等においては粉塵が外部に流出しな
いように集塵装置か設けられている。この装置の代表的
なものとしては、粉塵含有ガスをファン等によって吸引
し、バグフィルタ−により粉塵を分離収集する集塵装置
か知られている。[Background of the Invention] Recently, wood processing factories and the like have been provided with dust collectors to prevent dust from flowing outside. A typical example of this device is a dust collector that sucks in dust-containing gas with a fan or the like and separates and collects the dust with a bag filter.
かかる集塵装置においては自然発火や失火ないし人為的

り、例えば本来火種の残ったタバコの吸殻等を吸引する
ようなことはあってはならないことであるが、時として
そのようなことか起こり、しかもタバコの吸殻等を吸い
込んで数時間ないし十数時間後に発火することさえあり
、思わぬ災害を引き起している。Such dust collectors have the problem of fires caused by spontaneous combustion, misfires, or artificial ignition (from cigarettes, etc.); for example, it is important to avoid inhaling cigarette butts with residual sparks. Although this should never happen, sometimes such things happen, and cigarette butts can catch fire several hours or even hours after inhaling them, causing unexpected disasters.
かかる火災を知らせる装置として、近時、各種温度ない
し煙センサーか用いられるようになってきた。該センサ
ーはその感度か高くなった反面誤動作も多く、そのため
この誤動作にもかかわらず、消火装置が作動される場合
か多い。Recently, various temperature or smoke sensors have come to be used as devices to notify such fires. Although the sensitivity of these sensors has increased, they often malfunction, and therefore fire extinguishing systems are often activated despite these malfunctions.

のｂｔ動自体も行えなくなり、センサー誤動作の弊害が
あまりにも大きいという欠点があった。Looking at the fire extinguishing methods used in conventional dust collectors, most of the fire extinguishers are water extinguishers because of its simplicity, or in the case of water extinguishers, if water is applied even though the sensor is malfunctioning, bag filters and ducts can be damaged. The system became soaked with water, and the device itself became unusable unless the filter was replaced.As a result, the factory's BT operation itself became impossible, and the problem of sensor malfunction was too great.
そこで１人が近付くと危険である場所、或いは物理的に
侵入することか困難である場所に対する従来の消火技術
をみると次の通りである。Conventional fire extinguishing techniques for places that are dangerous for one person to approach or places that are difficult to physically enter are as follows.

した集塵機の火災防止装置が開示されている。■ Utility Model Application No. 58-115249 includes a tank containing water or extinguishing agent, a high-pressure pump connected to this tank, a hose connected to this high-pressure pump, and a reverse jet installed at the end of this hose. A fire extinguishing system for duct fires, etc., which is composed of a nozzle and a In addition, dampers with a normally closed structure are installed in the dust suction path connected to the dust side of the collector B and in the middle of each of the above-mentioned intake paths, and both dampers and the motor of the suction fan When power is supplied, a power circuit is connected to open both dampers and drive the motor, and a sensor circuit is connected to the two sensors above, and this sensor circuit detects the detection amount of both sensors to the set value. When this happens, an activation signal is sent to the alarm circuit and power cutoff circuit, respectively.
A fire prevention device for a dust collector is disclosed which is configured to output a required alarm and shut off the power circuit.

−が口塞りを起してしまうことがあった。Therefore, the present inventor attempted to apply the technique (2) above to a dust collector. In other words, using a fire extinguishing agent instead of water can prevent the bag filter from becoming waterlogged, but by using an injection nozzle connected to a high-pressure pump with a hose, it is possible to inject the fire extinguishing agent into every corner of the dust suction line. It is difficult to spread the extinguishing agent over the entire area, and if the extinguishing agent is inserted deep into the dust bag, the bag filter may become clogged.

かった。Next, the present inventor attempted to apply the technique (2) above to a dust collector. However, if the dust collector is for sawhorses,
When the fire source, such as a cigarette butt, or sawdust goes deep into the dust collector, the fire extinguishing method described in (2), which simply cuts off the air, cannot actually extinguish the fire, and in the end, water has to be used.

的とする。Therefore, the present invention is capable of reliably extinguishing a fire without causing any trouble, and even if fire extinguishing agent is sprayed due to sensor malfunction, etc., the fire can be restored without stopping factory operations. The purpose is to provide a fire extinguishing method in dust equipment.
［問題点を解決するための手段］
本発明者は上記目的を達成すべく鋭意検討を重ねた結果
本発明に至った。[Means for Solving the Problems] The present inventor has made extensive studies to achieve the above object, and as a result has arrived at the present invention.
即ち、本発明に係る集塵装置における消火方法は、吸塵

方法において、前記吸塵機の吸引吐出力を利用して前記
吸塵ラインに粉末消火剤を供給することを特徴とする。That is, a fire extinguishing method in a dust collector according to the present invention is a fire extinguishing method in a dust collector in which a dust suction machine supplies a dust-containing gas to a bag filter through a dust suction line and separates dust. The powder fire extinguishing agent is supplied to the dust suction line using the following method.
以下、本発明の方法を実施するための装置の一例を添付
図面に基き説明する。An example of an apparatus for implementing the method of the present invention will be described below with reference to the accompanying drawings.

又は不定期的に系外に排出される。To explain the specific fire extinguishing method, first of all, normally air containing dust is sucked! The dust-containing air η is sucked in by the J machine 1 and supplied to the collecting section 6 through the suction line 1 and the discharge line 3, the dust is separated by the bag filter 5, and the clean air is discharged from the collecting section 7 to the outside of the system. is discharged out of the system from the dust outlet 8 regularly or irregularly.

を発生する重ソウ粉末が好ましい。The powder fire extinguishing agent that can be used in the present invention may be one that is commonly used. For example, heavy sodium sulfur powder, which generates carbonated air when exposed to fire heat, is preferable.
なお手動で粉末消火剤を供給するには、市販の粉末消火
器を用いてもよい。Note that a commercially available powder fire extinguisher may be used to manually supply the powder fire extinguisher.
以上１本発明の詳細な説明したが、本発明の実施態様は
上記に限定されず、例えば吸塵機を集塵装置における粉
塵含有エアーの供給側でなく。Although the present invention has been described in detail above, the embodiments of the present invention are not limited to the above, and for example, the dust suction device is not provided on the dust-containing air supply side of the dust collection device.
吐出側に設けるようにしてもよい。It may also be provided on the discharge side.

ない。[Effects of the Invention] According to the present invention, since powder extinguishing agent is used, even if the powder is supplied to the bag filter in the event of malfunction of the sensor, the powder extinguishing agent will not be supplied to the bag filter because it has the same properties as the dust to be treated. There is no chance that the product will get soaked with water and become unusable.
