Abstract

The invention relates to the technical field of the design of chemical reactors and discloses a novel high-throughput micro-channel reactor provided with multiple layers of spirally winding tubes. The reactor mainly comprises reactant inlet and outlet sections, inlet and outlet glands, flanges, inlet and outlet tube plates, stainless steel capillary tubes, a fixed pad strip, a drum, a winding drum, constant-temperature medium inlet and outlet sections, baffles, left and right supports, a central support tube and a support piece, wherein two ends of the central support tube are connected with the inlet and outlet tube plates, and the winding drum and the central support tube are located on a same axis and welded and connected through the support piece; the stainless steel capillary tubes spirally wind around the winding drum in a multi-layer manner, spiral directions of adjacent winding layers are opposite, multiple reaction tube bundles which take the winding drum as the circle center and have different circle diameters are formed, and two ends of each stainless steel capillary tube are connected onto the inlet and outlet tube plates respectively; the inlet and outlet glands are connected with the inlet and outlet tube plates respectively through the flanges. The reactor has the advantages of high throughput, high heat transfer capacity, high synthetic rate, safety, high efficiency, low machining cost, capability of realizing continuous production, easiness in parallel enlargement and the like.

Description

technical field [0001] The invention relates to the technical field of chemical reactor design, in particular to a microchannel reactor for the synthesis of chemical intermediates and the preparation of biomedical materials, and in particular to a novel high-throughput multi-layer spiral wound tube microchannel reactor for use in in some fast exothermic reactions. Background technique [0002] Reactor is the equipment to realize the reaction process, which is widely used in chemical industry, oil refining, metallurgy, light industry and other industries. Commonly used reaction equipment includes mixing tanks, extraction towers, static mixers, etc., which have a large processing capacity and can meet the needs of large-scale production. However, generally speaking, these mixing devices provide fluids with macro-scale mixing, which has disadvantages such as uneven mixing, large power consumption, large equipment volume, and difficulty in continuous production.
