集するための集塵方法に関する。[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a method for collecting dust from urethane resin combustion gas, and more specifically to a method for collecting dust from urethane resin combustion gas. The present invention relates to a dust collection method for collecting dust in combustion gas generated when urethane resin such as urethane foam or urethane rubber is subjected to heat treatment such as thermal welding treatment.
（従来の技術）
従来、このような集塵方法の代表的なものとして、濾布
や濾紙等の濾材を用いた濾過集塵装置（いわゆるバグフ
ィルタ−）による方法がある。(Prior Art) Conventionally, as a typical example of such a dust collection method, there is a method using a filtration and dust collection device (so-called bag filter) using a filter medium such as a filter cloth or a filter paper.

り、目詰りによる濾材の取替えを頻繁に行なわなければ
ならないという不具合があった。(Problems to be Solved by the Invention) However, when urethane resin is heat-treated, phenolic compounds, amines, aldehyde compounds, chlorine compounds, etc. are generated by thermal decomposition, and these substances and soot-like char are the main components. Then, a highly sticky tar component in the form of a mist is formed. And because this tar component sticks to the filter media,
Even if a so-called vibration type or reverse jet type dusting mechanism is activated to prevent clogging after a certain amount of dust has been collected on the filter, it becomes difficult to shake off the collected dust, and the filter must be replaced due to clogging. There was a problem in that it had to be done frequently.
そこで本発明は、ウレタン樹脂の燃焼ガスに含まれるミ
スト状タール成分の粘着性を失わせることをその解決す
べき技術的課題とする。Therefore, the technical problem to be solved by the present invention is to eliminate the stickiness of the mist-like tar component contained in the combustion gas of urethane resin.
（問題点を解決するための手段）
上記課題を解決するための技術的手段は、ウレタン樹脂

塵装置によつ′Ｃ捕集する集塵方法であって、
前記燃焼ガスに予め粉状の消石灰を分散状態で混合させ
た後、前記濾過集塵装置を通過させることである。(Means for Solving the Problems) The technical means for solving the above problems is to use a filtration and dust collector to collect dust in the combustion gas generated by the heat treatment of urethane resin. In the method, the combustion gas is mixed with powdered slaked lime in a dispersed state in advance, and then passed through the filtration and dust collector.
（作 用）
ミスト状タール成分が消石灰の粉末と接触することによ
り粘着性のないドライパウダー状の物質となる。(Function) When the mist-like tar component comes into contact with the slaked lime powder, it becomes a dry powder-like substance with no stickiness.
このような作用は、消石灰がアルカリ性であって、フェ

て上記の塩類や重合物およびアミン類を凝固させ、結果
的にタール成分の粘着性を失わせることによるものと思
われる。This effect is due to the fact that slaked lime is alkaline and forms salts with phenolic compounds and chlorine compounds, and does not promote the polymerization of aldehyde compounds. This is thought to be due to the coagulation of amines and the resulting loss of stickiness of the tar component.
なお、燃焼ガスの刺激臭の主たる原因であるホルムアル
デヒドを重合あるいは中和させることにより、刺激臭を
なくするという作用もある。Additionally, by polymerizing or neutralizing formaldehyde, which is the main cause of the irritating odor of combustion gas, it also has the effect of eliminating the irritating odor.
（実施例） 次に本発明の一実施例を図に基づいて説明する。(Example) Next, one embodiment of the present invention will be described based on the drawings.

動を与え得るようになっている。The filtration and dust collection device 1 used in this embodiment has a duct 3 extending from a hood 2 installed at an appropriate position close to a workplace where urethane resin is heat-treated. The slaked lime supply hopper 5 of the metering device @ 4 is connected, and the tip of the duct 3 is guided to the intake side of a dust collector 7 equipped with a filter cloth 6 supported by a frame (not shown), and from the exhaust side of the dust collector 7. A duct 9 with a blower 8 is installed in the middle thereof, and its tip is connected to an exhaust chimney 10. A dust outlet 11 that can be opened and closed is provided at the bottom of the exhaust side of the dust collector 7, and the frame supporting the filter cloth 6 can be vibrated by a vibration device (not shown).
本実施例は、上記の濾過集塵装置１を用いて、次のよう
に行なわれる。This example is carried out as follows using the above-mentioned filtration and dust collection device 1.
まず、ホッパ５に粉状の消石灰１２を充填する。First, the hopper 5 is filled with powdered slaked lime 12.
この消石灰１２は風の作用により気体中にダスト状に分
散し得る微細な粉状であれば良く、その粒度は特に限定
されない。The slaked lime 12 may be in the form of fine powder that can be dispersed in the form of dust in the gas by the action of wind, and its particle size is not particularly limited.
そして、ウレタン樹脂の加熱処理を開始すると同時にブ
ロワ８を作動させて、ウレタン樹脂の燃焼ガスを含む空
気をフード２よりダグ１〜３中へ吸引する。Then, at the same time as the heat treatment of the urethane resin is started, the blower 8 is operated to suck air containing the combustion gas of the urethane resin from the hood 2 into the dugs 1 to 3.
これと同時に調量装置４を所定量間口することにより、
ホッパ５中の粉状消石灰１２をダ渋ト３中へ導入する。At the same time, by opening the metering device 4 by a predetermined amount,
Powdered slaked lime 12 in the hopper 5 is introduced into the dust 3.
このとき、ダクト３中を図の矢印方向へ移動・する吸引
空気の風圧により消石灰は分散状態で燃焼ガスと混合さ
れ、前述した作用により燃焼ガス中のミスト状のタール
成分が粘着性のないドライパウダー状の物質となる。At this time, the slaked lime is mixed with the combustion gas in a dispersed state due to the wind pressure of the suction air moving in the direction of the arrow in the duct 3, and the above-mentioned action converts the mist-like tar component in the combustion gas into a non-sticky dry. It becomes a powder-like substance.
なお、消石灰の混合量は燃焼ガスの組成や吸引空気中の

例として、吸引空気１ＴｒＬ３中にミスト状タール成分

消石灰を混合させても良い。The amount of slaked lime mixed is arbitrarily determined depending on the composition of the combustion gas and the amount of mist-like tar component in the suction air, and cannot be determined by law.
For example, if 1 g of mist tar component is contained in 1TrL3 of suction air, 2 g of slaked lime may be mixed with 1 m3 of suction air.
このようにして消石灰が混合された吸引空気は集塵′ｅ

ら煙突１０を通過して大気中に還元されるのである。The suction air mixed with slaked lime in this way collects dust.
At step a7, tar components and other dust that became dry powder when passing through the filter cloth 6 are collected, and the air is clean and free from the irritating odor caused by formaldehyde, as shown by the arrow in the figure. Then, it passes through the chimney 10 from the ducts 1 to 9 and is returned to the atmosphere.
そして、濾布６に一定量のダストが捕集されて通気性が

外へ搬出される。When a certain amount of dust is collected on the filter cloth 6 and the air permeability becomes poor, the filter cloth 6 is vibrated by the vibration device to shake off the dust. At this time, since the tar component is also collected in the form of dry powder, it is easily brushed off. This dust is carried out of the apparatus through the dust outlet 11.
次に、本実施例の効果を確認するために行なった試験に

に捕集されたダスト分を取出して比較観察した。The hopper 5 is separately filled with dry powdered flour, bentonite, silica sand, sulfur, flux, cement, and slaked lime, and each of the powders is sucked into the air by generating urethane resin combustion gas under the respective conditions. 2'j against
Filter cloth 6 is filtered while mixing at a ratio of /m3.

Operation can be performed easily and reliably, and work efficiency can be improved by extending the life of the filter medium and reducing the frequency of its replacement.
