Device and method for spraying continuous reaction

Abstract

The invention provides a spraying continuous reactor. According to the invention, the reactor is provided with fluid spray guns; the principle of high-speed flowing of inert gas is utilized to micronize liquid; rapid dissipation of energy is realized through instantaneous violent impact of two high-speed flowing fluids; so the segregation degree between the two fluids is rapidly reduced, and the purpose of rapid mixing is achieved. The inert gas can carry away most of heat while a collision reaction occurs, so the reaction is facilitated. The impact fluids can be designed into a symmetrical structure or an asymmetric structure. Fluid inlets can be designed to be in a high-pressure nozzle form, and can also be designed to be in a form that two streams of fluids coming from a double-fluid nozzle and conveyed by gas are atomized by the nozzle. After atomization, the two fluids impact each other and are mixed with each other in the reactor. Results of experimental studies show that collision mixing of droplets with droplet diameters in a range of about 200-300 [mu] m is more beneficial for uniform mixing of liquid.

Description

technical field [0001] The invention belongs to the technical field of the pharmaceutical industry, and in particular relates to a spray continuous reaction device and method. Background technique [0002] In industrial production, the equipment that uses the turbulent mixing mechanism to achieve liquid-liquid mixing mainly includes stirred tank mixers, jet jet mixers, impinging flow mixers, static mixers, dynamic mixers, etc., which correspond to the process of mixing fluids in the form of mechanical stirring. The macroscopic mixing time is relatively long, and the process is mainly controlled by macroscopic mixing. In industrial production, about 85% of the liquid-liquid mixing process is completed in a stirred tank. Now most of the reaction equipment uses mechanical stirring and batch production. On the one hand, the reaction is incomplete and the conversion rate is reduced; on the other hand, the labor intensity of the operators is high, and the operating cost is high. ...
