The described a kind of gas and liquid flowing inlet diffuser that has guide functions of the utility model; It is a member with streamlined structure, is arranged in the reactor inlet cylindrical shell, and the member top constitutes elliposoidal by arc shaped blade; The upper end of arc shaped blade is fixed on the same point; The lower end of arc shaped blade is separately fixed on the bracing ring, and the arc shaped blade number is 3-8, and the bracing ring circumference evenly distributes on the edge; The water conservancy diversion fin is arranged on the bottom of arc shaped blade, and the water conservancy diversion fin is parallel with reactor inlet tubular axis direction, and the upper end is fixed on the bracing ring, and the lower end is fixed on down on the bracing ring, and quantity is 3-8, evenly distributes at circumferencial direction; Following bracing ring is fixed by the support that is welded on the reactor inlet cylinder inboard wall; The outlet of reactor inlet cylindrical shell is 15 ° of-30 ° of angle of flare structures, and the below is provided with upper strata baffle plate and lower floor's baffle plate, and the upper strata retaining is fixed on the support for ring flat-plate, and lower floor's baffle plate is a porous plate, and it is inboard to be fixed in the upper strata baffle plate.
The concrete scheme of the utility model is: the member with streamlined structure is installed in the reactor inlet barrel in (1), and its top design is the ellipsoid shape, but is not occluding surface, but is made up of arc shaped blade; The blade bottom connects the water conservancy diversion fin, and fin is parallel with the Liquid Flow direction, can impel fluid to flow along flap surface is smooth.(2) cylindrical shell outlet being designed to angle of flare is 15 °-30 ° expansion structure, is beneficial to fluid and disperses.(3) below the cylindrical shell outlet, being provided with two-layer baffle plate convection cell is uniformly distributed with.
The lucite top of tower of one diameter 1000mm has the fluid intake pipeline of a diameter 100mm, height 500mm.At water flow velocity 20-30m
