適用されるオリゴマー、オイルミスト等の揮発性飛散物
の除去装置に関するものである。[Detailed Description of the Invention] (Industrial field of application) The present invention is a device for producing plastic films such as polypropylene, polyester, nylon, etc., particularly a device for removing volatile scattered substances such as oligomers and oil mist, which is applied to the stretching device. It is about.
(従来の技術) 従来延伸フィルムの製造にあたって最も一般的な方法
としては、温度制御された熱風を循環してフィルムの予
熱、延伸、熱固定及び冷却をする方法が採用されてい
る。(Prior Art) Conventionally, the most general method for producing a stretched film is to circulate hot air whose temperature is controlled to preheat, stretch, heat set and cool the film.
しかしこの方法においては、稼動中において前記熱風
中に昇華物、オイルミスト等が飛散してこれらが製造中
のフィルムに付着すると云う欠点をもっていた。なお、

る。However, this method has a drawback in that sublimates, oil mist and the like scatter in the hot air during operation and adhere to the film being manufactured. In addition,
Examples of the scattered substances include oligomers during polyester stretching and additive evaporation components during polypropylene stretching.
ところでこれらの飛散物を除去するため、従来は、例

れている。この方法は、酸化触媒層に白金等の貴金属を
担持させて、200〜250℃の比較的低温で燃焼させること
を特徴としている。By the way, in order to remove these scattered matters, conventionally, for example, as shown in JP-A-58-65731, polyester oligomers are passed through the oxidation catalyst layer at a normal operating temperature without further heating the hot air. A method of burning off is disclosed. This method is characterized in that a noble metal such as platinum is supported on the oxidation catalyst layer and burned at a relatively low temperature of 200 to 250 ° C.

化し実用的ではなかった。(Problems to be Solved by the Invention) However, even if the above-mentioned conventional method is applied to stretching of a polypropylene film, the hot air temperature is usually as low as 160 ° C., so that a sufficient combustion effect cannot be obtained. In addition, the performance was rapidly deteriorated by the catalyst poison of oil mist generated from the additive, which was not practical.

く、早期に破過する傾向がある。On the other hand, for example, Japanese Unexamined Patent Publication (Kokai) No. 60-97829 discloses a method for removing oligomers and oil mist by using an adsorbent such as activated carbon, alumina and clay, and it is said that activated carbon pellets are particularly effective. However, general adsorbents such as activated carbon have so-called selectivity, which limits the substances that can be adsorbed, and has the characteristic that the adsorption capacity decreases as the adsorption temperature rises. For example, the stretching temperature of the polyester film is 230 to 250 ° C., which is the temperature at which the adsorbed substance is usually desorbed from the activated carbon, and it is extremely inefficient to carry out the adsorption operation of the oligomer at this temperature, and a large amount of activated carbon I need. In addition, oil mists are generally difficult to adsorb and tend to break through early.

る。Further, the adsorbent which has reached the breakthrough, it is necessary to desorb the adsorbed substance by the desorption operation, but for this purpose, it is necessary to desorb at a temperature 150 to 200 ° C. higher than the adsorption temperature,
Generally, it is a form of entrusting the regeneration treatment to the adsorbent manufacturer.

It is an object of the present invention to provide a volatile scattering material removing device for a plastic film stretching device that can solve the problems and stably remove volatile scattering materials in hot air in various film stretching processes.
