産業上の利用分野
本考案は熱分解釜等の突沸事故を防ぐため釜本
体に取り付ける放爆弁に関するものである。[Detailed Description of the Invention] Industrial Application Field The present invention relates to an explosion valve that is attached to the body of a pyrolysis reactor to prevent bumping accidents.

た。Prior art and its problems Since this type of detonation valve is used in a high-temperature pot, the packing wears out rapidly and must be replaced frequently, and it is difficult to completely block gas leakage with asbestos packing. . Therefore, it is possible to use silicone packing, which has excellent sealing properties, but silicone packing has poor heat resistance and contact resistance, and is not suitable for items that are exposed to high temperatures and come into contact with pyrolysis gas, such as pyrolysis reactors. It was difficult to use.
問題を解決するための手段
本考案はこのような欠点を解消すべく案出した
もので以下図面にもとづいてその実施例を詳述す
る。Means for Solving the Problems The present invention has been devised to eliminate such drawbacks, and embodiments thereof will be described in detail below based on the drawings.
釜本体Ａの上部に取り付ける圧力逃し筒体１と
該筒体１をバネ３により常時押圧している天板２
とからなる放爆弁において、天板２又は圧力逃し
筒体１の周縁には石綿パツキング４を嵌装すると
ともにその外周にはシリコンパツキング５を嵌装
してなるものである。 A pressure relief cylindrical body 1 attached to the upper part of the pot body A and a top plate 2 that constantly presses the cylindrical body 1 with a spring 3.
In this detonation valve, an asbestos packing 4 is fitted to the periphery of the top plate 2 or the pressure relief cylinder 1, and a silicone packing 5 is fitted to the outer periphery thereof.
作用、効果
本考案は以上のような構造であるので熱分解釜

効果が期待できることになる。Functions and Effects Since the present invention has the structure described above, when used in a high-temperature furnace such as a pyrolysis furnace, it has the following functions and effects.
The effect can be expected.
常時天板はバネによつて圧力逃し筒体の上縁を

る。 The top plate is always pressed against the upper edge of the pressure relief cylinder by a spring, but in this case, the silicone packing has excellent adhesion, so gas leakage can be completely blocked. On the other hand, since asbestos packing is fitted around the inner periphery of the silicone packing, it can almost completely block out decomposed gas, making it possible to suppress corrosion of silicone packing, which has weaknesses in heat resistance and contact resistance. It can extend the life of packing.

とになる。 Note that if water jackets 6 and 7 are provided to allow cooling water to pass through the top plate 2 and the packing contact portion of the cylinder 1, damage to the packing due to high temperatures can be avoided. 6a is a water supply port of the water jacket 6 in the cylinder, 6b is a drain port, and 6
c is a partition plate. Further, 7a is a water supply port for the water jacket 7 of the top plate 2, 7b is a drain port, and 7c is a partition plate. In this case, the cooling water is first supplied to the water jacket 8 provided on the outer edge of the pot body A, and after going around the water jacket 8, it hits the partition plate in the jacket 8 and is supplied from the outlet to the water jacket 9 on the outer edge of the lid body B, where it is cooled. The water goes around the cylinder 1 in the same way.
If the water jackets 6 and 7 of the top plate 2 are connected by a pipe so that the water goes around and is discharged, the main body of the detonation valve can be cooled more effectively.
