The invention discloses an up-down opposite-flushing type micro-interface strengthening reaction device and a method. Hydrogen and residual oil raw materials with catalysts enter a bubble crusher after being preheated to form a micron-sized bubble system, then enter a bubbling reactor from a first discharge port of the bubble crusher at the top and a first discharge port of the bubble crusher at the bottom respectively, and the two micron-sized bubble systems oppositely jet in the bubbling reactor to carry out hydrogenation reaction under the action of the catalysts. The reaction device and the method have the advantages of ultralow hydrogenation reaction pressure, small gas-liquid ratio, large gas-liquid mass transfer area, high reaction rate, low energy consumption, flexible process, high production safety and the like. |
