NOVELTY - Device comprises an impinging stream structure and a rotary filler bed including a shell, a hollow circular rotor, filler and a rotating shaft. The impinging stream structure is non-limiting impinging stream structure including main feed pipe and sleeve having different pipe diameters. The main feed pipe is inverted T-shaped pipe structure, comprising a feed section and a discharge section mutually vertical to each other. The sleeve is set at the outer feed section of the main feed pipe. The sleeve is set with a discharge section corresponding to the bottom of the main feed pipe.    USE - The device is useful for continuous preparation of methanol emulsified diesel oil (claimed).    ADVANTAGE - The device: changes two-phase flow impact; increases two phase flow impact; and has high yield.    DETAILED DESCRIPTION - Device comprises an impinging stream structure and a rotary filler bed including a shell, a hollow circular rotor, filler and a rotating shaft. The impinging stream structure is non-limiting impinging stream structure including main feed pipe and sleeve having different pipe diameters. The diameter of the sleeve is larger than the main feed pipe diameter. The main feed pipe is inverted T-shaped pipe structure, comprising a feed section and a discharge section mutually vertical to each other. The sleeve is set at the outer feed section of the main feed pipe. The feed section of the main feed pipe far away from a terminal end part of the discharge section is set with a main feed pipe feeding port. The feed section of the main feed pipe close to one side of the sleeve comprises multiple main feed pipe discharge holes. The sleeve away from the main feed pipe discharge section at one end is provided with sleeve feed port. The sleeve is set with a discharge section corresponding to the bottom of the main feed pipe, and is provided with multiple main feed pipes and discharge holes. The discharging hole is coaxially set with a sleeve. The rotor of the non-limiting impinging stream structure is set with an inner cavity along the rotor axis direction. The rotor cavity is set between the main feed pipe discharge hole and sleeve discharge hole center position along a symmetrical axis. The main feed pipe feeding port is connected to a methanol storage tank (5). The feed inlet is connected to a diesel oil storage tank (3). The liquid outlet of the rotary filler bed is connected to a product storage tank (6). An INDEPENDENT CLAIM is also included for continuous preparation of methanol emulsified diesel oil using the device, comprising introducing a hydrophilic emulsifier and co-emulsifier into a methanol storage tank, stirring uniformly to form an aqueous phase, introducing lipophilic emulsifier into a diesel oil storage tank under stirring to form an oil phase, mixing the aqueous phase and oil phase in a non-impinging stream reactor for collision, macroscopic mixing and primary micro-mixing processes, allowing to enter into high speed rotating filler after the collision, maintaining the materials under high shearing force to ensure high turbulent energy dissipation rate, rapid completion of micro-mixing process to form water-in-oil type methanol emulsified diesel oil.
