種の問題があつた。 As mentioned above, if combustible powder or granules are included, the combustible granules in the gas or the separated combustible granules may spontaneously ignite due to the high gas temperature, resulting in a fire or explosion. Accidents are likely to occur, and wet solid-gas separation means, such as showering the gas, have conventionally been employed. However, in the case of the wet method, there are problems in handling and post-processing of the recovered powder and granules, and it is not suitable for recovering and utilizing waste heat of gas. When applying the treatment, there were various problems such as the tendency to cause clogging and making it unsuitable.
本発明は、上記実情に鑑みて、上述の諸問題の
無い乾式固気分離手段を採用しながら、火災や爆
発事故を防止できるようにする事を目的とする。 In view of the above-mentioned circumstances, the present invention aims to prevent fires and explosions while employing a dry solid-gas separation means that does not have the above-mentioned problems.

提供できるようになつた。 In summary, the solid-gas separator according to the present invention has the following features:
It is characterized by being equipped with a device 8 for supplying non-combustible powder to the gas containing the self-combustible powder to be subjected to solid-gas separation. Spontaneous combustion of the self-combustible powder can be effectively suppressed by isolating the self-combustible powder and granules, and by coating and cooling the self-combustible powder. the result,
It is possible to collect powder and granules in a dry state, which is relatively easy to handle and post-process, and even if a back filter is used, it is easy to avoid clogging due to moisture, and even if gas Although it can be applied even when waste heat is recovered and used, fires and explosions due to spontaneous combustion can be reliably prevented, and overall, it has become possible to provide a solid-gas separation device that is both excellent in versatility and safe.
