Described back-up ring diameter is lower than the lower end of riser greater than draft tube diameter and lower end, and shield links to each other back-up ring with riser, and back-up ring and shield form annular space jointly in the lower end of riser.This structural design can enter part the drop of riser and collect, and helps improving separative efficiency.
45 degree grooves are all adopted in the upper end of described outlet lower end and riser, and the internal diameter of outlet is less than the internal diameter of riser, and the lower end of outlet forms the annulus a little less than the upper end of riser.This gap structure is simple, the small amount of drop that enters riser can be separated, and further improves separative efficiency.
Described deflection plate below is provided with the baffle plate of two staggered inclinations, and the updip direction of baffle plate is identical with the air-flow direction of rotation.The updip direction of baffle plate is identical with air-flow eddy flow direction can stop swirling eddy once more isolated liquid carry and cause separative efficiency to reduce, play stable liquid.
Described riser below is provided with the deflection plate of center drilling, adopts return duct to connect dividing plate top and deflection plate center drilling, will cause the deflection plate center by isolated liquid from the annulus; Deflection plate has the effect of current stabilization, avoids liquid to be carried the reduction separative efficiency once more by the gas of eddy flow.Isolated liquid process return line flow can rationally be utilized the center low-pressure area of cyclonic separation formation to deflection plate center drilling place from the annulus in addition, and guiding liquids flows.
In sum, the characteristics of the utility model gas-liquid knockouts are: the principle of utilization cyclonic separation, characteristics according to gas-liquid two-phase adopt novel structural designs such as above-mentioned two inlets inlet, riser, back-up ring, shield, deflection plate, return duct and baffle plate, separate for three times that have realized drop, can isolate drop efficiently, have the advantage that treating capacity is big, operating flexibility is high, pressure drop is low, separative efficiency is high.
