Title:
噴霧熱分解法による微小粒子の製造装置
Document Type and Number:
Japanese Patent JP6851230
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide an apparatus capable of stably manufacturing microparticles by a spray pyrolysis process, the apparatus preventing a furnace core tube from cracking and splitting caused by thermal shock or thermal distortion to improve durability of the furnace core tube.SOLUTION: In a manufacturing apparatus of microparticles, a raw material solution is sprayed into a spray pyrolysis apparatus having a drying zone and a heating zone and subjected to drying and pyrolysis. A furnace core tube of a furnace is made of ceramics and linearly divided into two or more parts in the longitudinal direction. The parting planes are tightly adhered to each other and have an angle of 45 degrees or more and 70 degrees or less to an arc tangent of the upper edge face of the furnace core tube.SELECTED DRAWING: Figure 1
