The evaporating column of the present invention can make material flash distillation in tower, isolate vehicle repair major, and eliminate the liquid foam in vapour phase
Entrainment.Therefore, evaporating column of the invention have the advantages that separative efficiency it is high, without liquid foam entrainment.Below with reference to the accompanying drawings 1 this is described
The bright course of work for being suitable for the detached evaporating column of COMPLEX MIXED material.
Fresh feed liquid enters heater 13 from the Jing circulating pumps of fresh feed liquid feed pipe 12, is heated to entering heat after design temperature
Material feed pipe 14, then Jing material liquids feed pipe 2 is into flash distillation in tower body 1, and substantial amounts of steam is flashed off rapidly, forms flow at high speed
Liquid-vapor mixture.Liquid-vapor mixture is separated due to density contrast in tower, and vapour phase rises along tower, and liquid discharge material is flowed through under liquid phase
Pipe 7 discharges tower body 1, and because vapour speed is very fast, the vapour phase of rising can carry substantial amounts of liquid foam secretly, and the liquid foam is by many vaporific droplets
Composition, its composition is identical with the liquid phase for flashing off.
The steam flow of rising first passes around the first separation bed 3, and the liquid foam in steam flow separates bed 3 and collides simultaneously with first
Aggregation forms big drop and flows down, and vapour phase then continues to ascend into the second separation bed 4 through the first separation bed 3, completes first
Level foam removal effect.
Second separates bed 4 separates the liquid foam that bed 3 is more fine and closely woven, in further trapping steam flow compared with first.Second separates
The top of bed 4 is rinsed using flushing water, and flushing water separates bed flush pipe 6 and is sprayed at second from the Jing second of flushing water feed pipe 11
The upper surface of bed 4 is separated, the second separation bed is rinsed, prevent it from blocking.
Because the conical head of the bottom of whirlwind liquid knockout 5 separates whirlwind liquid knockout 5 with tower body 1, thus rise steam flow from
The Jing vapour phase communicating pipes 8 of tower body vapour phase connected entrance 801 at the top of tower body 1 tangentially enter whirlwind liquid knockout 5 along whirlwind liquid knockout 5,
High speed steam flow rotates around the axis of whirlwind liquid knockout, and because vapour phase is very big with the density contrast of liquid foam, both are very big because rotating bad student
Centrifugal force it is poor, the micro liquid foam of remaining is thrown toward the internal face of whirlwind liquid knockout 5 in vapour phase, Jing liquid phase communicating pipes 9 flow to tower
The middle and lower part of body 1, the central tube 501 for being eliminated whirlwind liquid knockout 5 described in vapour phase Jing of liquid foam is discharged along vapour phase discharge nozzle 10
Tower body 1, completes third level foam removal effect.
The vapour phase that the evaporating column of the present invention is flashed off separates bed, the second separation bed and whirlwind liquid knockout three by first
Level foam removal effect, thoroughly eliminates the liquid foam entrainment in vapour phase.
