Technical Field
The invention belongs to the field of reactors, and particularly relates to a tubular gas-liquid homogeneous reactor.
Background
The existing reaction (such as hydrogenation reaction, oxidation reaction, oxo aldehyde hydrogenation reaction and the like) of liquid-phase materials and gas-phase materials is difficult to form uniform distribution with the liquid-phase materials in all tubes of a reactor because the gas-phase materials are easily subjected to external environmental factors such as resistance, temperature, flow forms and the like to form irregular dispersion characteristics, so that the reaction effect in different tubes of the same reactor is quite different, hot spots and heavy component generation are easy to form, the raw material conversion rate and the selectivity of target products are influenced, the overall reaction effect is not ideal, and only measures of reacting the gas-phase materials with the gas-phase materials can be adopted to solve the problems.
At this time, the liquid phase materials need to be gasified into gas phase materials, which not only greatly increases energy consumption, but also generally reduces the volume space velocity of the catalyst (calculated by reaction raw materials) in the gas phase reaction, which results in much higher loading of the catalyst and the volume of the reactor than in the liquid phase reaction, increases more investment cost, and limits processing capacity. Meanwhile, part of liquid materials cannot be gasified under the corresponding reaction temperature and pressure, so that a fixed bed large circulation ratio reaction system is forced to be adopted, and the operation investment is high and the energy consumption is high.
The conventional micron-sized distribution pipes are generally internally provided with gas-phase materials, liquid-phase materials are arranged outside the pipes, a single distribution pipe is generally arranged at a place where the micron-sized distribution pipes are used, the gas-phase materials are diffused into the liquid-phase materials outside the pipes from the inside of the pipes, the distribution mode is often used for a butyraldehyde oxidation reactor, the distribution mode is uniformly distributed in the surface area of the distribution pipe, and large bubbles are easily formed in other liquid-phase material areas far away from the distribution pipe again, so that the reaction effect is poor.
How to adopt effective means to realize the uniform distribution of liquid phase materials and gas phase materials in all the tubes of the reactor is a technical difficulty to be solved in the field.
