Continuous liquid-liquid homogeneous reactor

Abstract

According to the continuous liquid-liquid homogeneous reactor, at least one reaction tube nest is arranged in a sleeve, flange plates are fixedly arranged at the two ends of the sleeve, the two ends of the reaction tube nest are fixedly connected with the flange plates, and a cold and hot medium inlet and a cold and hot medium outlet are further formed in the tube wall, close to the two ends, of the sleeve. At least one sleeve provided with a reaction tube nest is fixedly arranged in the box body, a middle thermal insulation filler is also arranged in the box body, and the outer wall plate is a detachable module sealing plate. The reactor is formed by arranging one or more reaction tube nests, a liquid inlet and a liquid outlet are connected through flanges, and the required connection mode can be changed according to needs. The cold and hot medium inlets and outlets are connected through pipe welding, and the cold and hot medium inlets and outlets on a plurality of sleeves can be welded in parallel. The reaction kettle is used for a gas-phase or liquid-phase continuous reaction process, is efficient, avoids potential safety hazards in the production process of a traditional reaction kettle, and improves the product quality and stability. In chemical production, the reactor can be suitable for intermittent operation processes, and can also be suitable for continuous operation processes through a single reactor or multiple reactors connected in series.

Description

technical field [0001] The patent of the present invention relates to a liquid-liquid homogeneous reactor used in the field of organic chemical synthesis, especially a continuous liquid-liquid homogeneous reactor. Background technique [0002] In the liquid-liquid homogeneous reactor in the prior art, the liquid raw material is added dropwise from a high-level tank, and the liquid raw material solution is configured by stirring, temperature control, etc. to configure the reaction environment to fully react the mixture. In addition to controlling the reaction intensity, the target product is finally extracted. The gap stirred tank reactor has been mostly used, and its basic structure mainly includes a reactor shell, a stirrer, a sealing device and a heat exchange device. This traditional reaction tank type reactor has the longest average residence time of materials and the largest reactor volume required to complete the same task. As chemical production becomes more and more...
