摘要：The invention discloses a dual-flow-baffle compound gasoline fractionator ofethylene unit, a quench oil circulation section is provided with micro baffles which are
arranged in parallel in the vertical direction at intervals, a vertex angle of the micro baffleranges from 90 to 139 degrees, symmetrical bevel edges at two sides of the vertex angleof the micro baffle are provided with symmetrical vertical hems, a medium oil circulationsection is provided with dual-flow trays which are arranged in the vertical direction andhave meshes with the diameter ranging from Φ 18 to 24mm, a diesel oil separationsection is provided with dual-flow trays which are arranged in the vertical direction andhave meshes with the diameter ranging from Φ13 to 24mm, and a gasoline separationsection is provided with dual-flow trays which are arranged in the vertical direction andhave meshes with the diameter ranging from Φ13 to 18mm. The gasoline fractionatorovercomes the frequent problem of polymer plugging in current plate-type fractionator,and has the prominent advantages of strong impact vibration resistance, reducedpressure of entire tower, high ethylene yield, outstanding energy-saving effect and beingcapable of ensuring long-term stable operation of this tower.
