The place of detail sees true order, little technology solves big problem – shallow talk ” channel effect ” reach its to improve

In the introduction of adsorptive type drier, often can mention ” of “ channel effect this noun, that after all what is ” of “ channel effect?
We distributing the air current inside dry tower not all, flow quickly among, the phenomenon that the brim sheds slow calls ” of “ channel effect.
Form a reason 1: Before compressing air to enter dry tower, can distributing through an air current implement, distributing in air current implement all round reach top, arranging a lot of alveolus dispersedly, compress air to enter adsorptive tower through these alveolus inside. And the structure of dry tower exit and entrance are identical, the flow that manages in dry tower center so is short, the technological process that or so brim manages is long; Tower way is older, the brim is in flow to grow more, form ” of “ channel effect more easily.
Form a reason 2: Distributing when air current inhomogenous when, a “ is formed easily to connect channel ” quickly in dry tower center, and sorbent fill is not quite even, close together, and the frequent switch of double tower, compress airy to be pounded repeatedly below, also can quicken the formation of “ channel ” .

Harm: Once “ channel ” is formed, compress air to be accelerated through speed, moisture still has not enough time by complete adsorption, compress air to had been passed, this comparatives from time to tome one part filling cannot get be usinged adequately, also formed adsorptive blind angle, cause sorbent utilization rate to be reduced greatly thereby, adsorptive effect is reduced apparently, dew point is elevatory.
Niumantaike is passed the following two main methods comeImprovementThis problem:
1. uses custom-built air current to distributing implement, combine ” of appropriate ratio of height to diameter of tower body “ , through reasonable design consideration, satisfying turnover while, still make sure air current can disperse reasonably equably, and pass emulate the effectiveness that imitate test and verify designs and dependability.
2. The active alumina of the high strenth with the bottom custom-built backfill in dry tower, big grain, not only can distributing air current, still can have bibulous effect at the same time.
