Description
Technical Field
The invention belongs to the technical field of gas-liquid reaction equipment, and particularly relates to a spray type gas-liquid two-phase reaction device.
Background
The reaction device is the core of chemical enterprises and is a place for synthesizing and decomposing substances. Since the gas-liquid reaction belongs to a two-phase reaction, the two-phase reaction is characterized in that the reaction can only be carried out at an interface. Because the gas density is low, the gas can be floated and gathered immediately after being introduced into the liquid phase, so that the gas-liquid contact area is rapidly reduced, and the gas-liquid phase reaction rate is rapidly reduced. Currently, researchers in the industry adopt various methods to increase the gas-liquid contact area in a reaction container. For example, CN210906149U, CN209465008U and CN209173918U are added into a reaction kettle by a stirrer, gas introduced into the kettle is dispersed into bubbles, and the residence time in a liquid phase is increased as much as possible by the movement of the bubbles. Also, the scholars blow gas into the liquid phase through the micropore device, reduce the volume of bubbles through micropores, increase the surface area, and utilize the process of gas ascending in the liquid phase to realize gas-liquid contact and increase the reaction rate, such as CN110404485A, CN208003959U, and the like. Also, researchers have devised baffle plates and the like to increase the gas-liquid reaction rate, such as CN 106268588A. However, none of the currently mentioned technologies can substantially change the gas-liquid reaction state, and in the gas-liquid reaction process performed in these reactors, the liquid phase part is a continuous phase, while the gas phase is a discontinuous phase, which is easy to gather and difficult to disperse into micro-bubbles, resulting in a short gas-liquid phase contact time.
