[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 operator is high and the operating cost is high

The invention provides a nitrosation continuous reaction device. A fluid spray gun is arranged on a reactor, liquid is micronized by utilizing the principle of high-speed flow of inert gas, and two fluids in high speed flowing are instantaneously and violently collided to realize rapid energy dissipation, thereby quickly reducing segregation degree between the two fluids, and reaching an aim of rapid mixing. A fluid inlet is designed as a two-fluid nozzle with gas delivery, with the two fluids passing through the nozzle mist. After atomization, the fluids are mutually impacted and mixed in thereactor. Experimental research finds that the collision mixing of the small liquid drops after the atomization of the two-fluid spray gun is more beneficial to the uniform mixing of the liquid.
