Description

Technical Field

[0001] This utility model relates to the field of reactors, and more particularly to bundled tubular reactors. Background Technology

[0002] With the development of modern industry, the technology for synthesizing methyl silicone oil is also constantly advancing. Especially in the production of small-molecule, low-viscosity methyl silicone oil, bundled tubular reactors have shown great application potential in the field of multiphase chemical reactions in recent years as a novel type of reaction device. These reactors possess advantages such as high mass and heat transfer efficiency and fast reaction rates, making them particularly suitable for the synthesis of small-molecule compounds. By tightly arranging multiple tubes into a bundle, not only can the material transport path be effectively shortened, but the uniform distribution of temperature and pressure during the reaction can also be ensured, thereby improving the selectivity and conversion rate of the reaction.

[0003] A bundled tube axial flow biological oxidation reactor, with Chinese patent application number CN201510026194.7, is described. It comprises an upper head, a feeding device, an intermediate body, a bundled tube, a vertical long-shaft pump, a lower cone, and a microporous aeration device. The upper head, intermediate body, and lower cone are connected by flanges. The feeding device is fixed to the upper head and communicates with the upper end of the bundled tube. The power unit of the vertical long-shaft pump is fixed at the center of the upper head, and the pump body is fixed at the center of the intermediate body. The bundled tube serves as the biological oxidation reaction zone, evenly distributed within the circumference of the intermediate body. The microporous aeration device is installed on the lower cone and communicates with the lower part of the bundled tube. The vertical long-shaft pump's circulating agitation eliminates shaft breakage caused by excessive torque of the large impeller; the shell-type heat exchange structure provides a more stable heat exchange environment for microbial oxidation, resulting in a more significant heat exchange effect; the closed design avoids environmental pollution caused by open mixing tanks; microporous aeration and circulating agitation convective oxidation improve gas utilization; this invention is more efficient, energy-saving, safe, and environmentally friendly than vertical mixed tank bio-oxidation reactors.

[0004] However, the above-mentioned patent has certain defects in use. Due to the long-term operation of the bundle tube, adhesion will occur, which will reduce the reaction efficiency. It is difficult to maintain in terms of disassembly, installation and cleaning. When the manifold needs to be cleaned, the downtime is too long, which affects the production efficiency.

[0005] Therefore, a bundled tubular reactor is proposed here to solve the problems mentioned above. Utility Model Content
