Development and research of a novel industrial scale microreactor
A new type of industrial microreactor for special field was developed to address the shortcomings of low processing capacity,limited equipment pressure and temperature resistance,low compactness,and low flow velocity in the current industrial field,the"etching and diffusion welding"process makes it have excellent pressure and temperature resistance performance.The manufacturing process makes the equipment highly compact and the internal channels flexible,which has great advantages in specific chemical processes.Three hybrid structures,i.e.AFMS,RFMS and CFMS were designed for the novel industrial scale microreactor.Numerical investigation was conducted to evaluate its mixing performance.Results show that mixing effect increases with the Reynolds number,and satisfactory mixing effect is achieved under turbulent condition.RFMS and CFMS can promote mixing process to some extent compared to AFMS,however,large pressure loss will occur.The ratio of mixing index to pressure drop further indicates that AFMS is the optimal structure for microreactor.When the Reynolds number is between 100 and 1 000,mixing index of AFMS is only 0.2~0.6 at the exit.mixing index of AFMS can reach 0.94 by replacing straight channel with zigzag channel without apparent pressure penalty.The research results provide important reference for the structural design of the novel microreactor prototype.
